2.2 PROPOSED CONSTRUCTION
F&R understands that the proposed development will consist of constructing 7 buildings with
associated parking and drive areas. Support structures such as a tank farm/utility yard and pipe
racks are planned as well. The buildings will be steel framed with slab-on-grade construction
(specific information regarding the proposed buildings is tabulated below) with a planned Finished
Floor Elevation (FFE) of 340 feet. Typical wall loads will range from 3 to 6 kips per linear foot
and first floor loads are on the order of 400 psf. We anticipate that there will be retaining walls
associated with loading dock areas and pits, however, no other walls were identified. Two
steepened slopes are planned to the north and south side of the project site and we assume other
slopes will be constructed. Once final grading plans are available, we would like an opportunity
to review them with respect to our recommendations. We anticipate that maximum cut and fills
across the site are not anticipated to exceed ± 20 to 30 feet from existing grades.

The recommendations in this report apply to the structures that will be built initially in Phase 1.
We recommend that additional borings be performed in the vicinity of the future buildings
planned in this phase as well as for Phases 2 and 3 prior to design of structures in those areas.
3.0 EXPLORATION PROCEDURES
3.1 FIELD
Thirty-seven (37) soil test borings (B-1 through B-36 and boring B-21A) were advanced as part of
this exploration (see boring locations on Figure No. 2 in Appendix A). The test borings were
advanced to depths ranging from approximately 10 to 53.5 feet below the existing ground surface.
Representatives of Bass Nixon and Kennedy established the boring locations in the field by
surveying and provided the ground surface elevations at each of the boring locations.

The test borings were advanced by an ATV mounted drill rig using 2-1/4" inside diameter (I.D.)
hollow stem augers for borehole stabilization. Representative soil samples were obtained using a
standard two-inch outside diameter (O.D.) split barrel sampler in general accordance with ASTM
D 1586, Penetration Test and Split-Barrel Sampling of Soils (Standard Penetration Test). The
number of blows required to drive the split barrel sampler three consecutive 6-inch increments is
recorded and the blows of the last two 6-inch increments are added to obtain the Standard
Penetration Test (SPT) N-values representing the penetration resistance of the soil. Standard
Penetration Tests were performed almost continuously to a depth of 10 feet and at a nominal
interval of approximately 5 feet thereafter. Water level measurements were attempted at the
termination of drilling and at select locations after a 24-hour stabilization period. The borings
were backfilled with auger cuttings.
A representative portion of the soil was obtained from each SPT sample, sealed in an eight-ounce
glass jar, labeled and transported to our laboratory for final classification and analysis by a
geotechnical engineer. The soil samples were classified in general accordance with the Unified Soil
Classification System (USCS), using visual-manual identification procedures (ASTM D 2488). A
Boring Log for each test boring is presented in Appendix B. Subsurface profiles, Figures 3 through
9, are located in Appendix A.
3.2 LABORATORY
Several soil samples were subjected to routine geotechnical index testing consisting of moisture
content, grain size distribution and Atterberg Limits determinations. Standard Proctor
compaction and California Bearing Ratio (CBR) testing was performed on four bulk samples
obtained to aid in pavement design. Triaxial testing was performed on two undisturbed samples
and one remolded sample to aid in evaluation of proposed slopes. Additional laboratory tests
were performed to evaluate the resistivity and corrosion potential of the on-site soils. The
purpose of the laboratory testing was to aid in our classification of the soil samples and
development of engineering recommendations. The laboratory testing was performed in general
accordance with applicable ASTM standards, and the results are included in Appendix C.

4.0 SITE & SUBSURFACE CONDITIONS
4.1 SITE CONDITIONS
The project site is approximately 160 acres in size (approximately 1/4 to 1/3 will be used for
Phase I) and is light to heavily wooded with pine and hardwood trees. Immediately prior to
drilling, the Phase I portion of the site was timbered. The higher elevations generally occur in
the central portion of the site (approximate elevation 359) and descends in all directions. Wet
weather drainage features are located on the east and west sides of the Phase I area and drain
towards the south and there is a creek located to the north of Phase I. There is approximately 50
feet of relief across the Phase I portion of the site.
4.2 REGIONAL GEOLOGY
The project area is located in the Deep River Triassic Basin (Chatham Group) consisting of
Triassic Age deposits. The deposits consist of maroon to gray arkosic sandstones, siltstones,
shales, and fanglomerates. The Triassic Deposits typically dip to the southeast at approximately
15° and are bounded on the southeast by the Jonesboro fault. Triassic deposits are frequently
intruded by diabase dikes (hard rock formations), although none were encountered in our borings.
Rock outcrops were not present at or in the immediate vicinity of the project site.
It should be noted that it is always a possibility that excavations may encounter diabase dikes
(which may require blasting or jack hammering for removal), even though we did not encounter
diabase in our borings.
4.3 SUBSURFACE CONDITIONS
Subsurface conditions, as indicated by the borings, generally consist of organic laden soils and
rootmat underlain by Triassic soils. The Triassic soils are sedimentary deposits formed from the
weathering, water transport and consolidation of the bordering residual soils. Triassic soils
generally transition with depth into Partially Weathered Rock (PWR).
Strata breaks designated on the Boring Logs and Subsurface Profiles represent approximate
boundaries between soil types. The actual transition from one soil type to another may be gradual
or occur between soil samples. General subsurface conditions encountered during our subsurface
exploration are described below. For more detailed soil descriptions and stratifications at the

boring locations, the attached "Boring Logs" and "Subsurface Profiles" should be reviewed.
Surface: An organic laden soil layer of approximately 2 to 6 inches in thickness was observed at
many of the boring locations. The organic laden soils generally consist of silty sand and sandy silt
with rootmat. Organic laden soils were observed in the vicinity of most of the borings but is not
noted on the boring logs due to surficial disturbance (timbering) at most of boring locations or the
borings were located within dirt/gravel roads. Based on our past experience, the organic laden soil
layer thickness can vary dramatically in wooded areas. We estimate stripping depths to be
between 6 to 12 inches thick and in isolated areas may reach as much as 24 inches.
Triassic Soils: Underlying the organic laden soils and at the surface at the boring locations that
were disturbed or in dirt roads, Triassic soils were encountered. The Triassic soils generally
consist of firm to very hard sandy silt, clayey silt, sandy clay (USCS - ML & CL) and loose to
very dense clayey sand and silty sand (USCS - SC & SM). At isolated areas, high plastic clays
and silts were observed (USCS CH& MH) in the upper 10 feet of the soil profile. Borings B-3,
13-16 through B-24, B-26, B-28, B-30 and B-36 were terminated in the Triassic deposit at depths
ranging between 10 and 30 feet below the existing ground surface. Standard Penetration
Resistances (N-values) obtained in the Triassic deposit ranged from 4 to 80 blows per foot (bpf).
The moisture condition of the soils was observed to be dry to moist.
Partially Weathered Rock: Partially Weathered Rock (PWR) was encountered at depths
ranging from approximately 3 to 35 feet below the existing ground surface. PWR is defined as
soils exhibiting N-values in excess of 100 blows per foot (bpo or harder than 50 blows per 6
inches. Standard Penetration resistances (N-values) obtained in the PWR ranged from 50 blows
per 4 inches of penetration to 50 blows per 2 inches of penetration. These borings were
terminated in PWR at depths ranging from 12 to 53.5 feet below the existing ground surface.
Borings B-8 through B-15, B-21A, B-25, B-27, B-29 and B-33 were terminated in PWR upon
auger refusal at depths ranging from 12 to 53.5 feet below the existing ground surface. Auger
refusal is defined as material that could not be penetrated with the drill rig equipment used on the
project. Auger refusal material may consist of large boulders, rock ledges, lenses, seams or the
top of bedrock. Core drilling techniques would be required to evaluate the character and
continuity of the refusal material.

4.4 GROUNDWATER CONDITIONS
In general, a majority of soils recovered from the test borings were dry to moist. Groundwater
was not encountered in the test borings immediately after drilling (IAD) or after a 24-hour period
except in boring B-9 where water was observed at a depth of 38 feet. We do not anticipate that
groundwater will be encountered within the proposed cut depths. The borings were backfilled
with auger cuttings.
It should be noted that groundwater elevations vary depending upon seasonal factors such as
precipitation and temperature. Due to the shallow depth that PWR was encountered and the
presence of relatively impermeable silts and clays, perched water conditions should be anticipated
following rain events and during seasonally wet periods. As such, groundwater conditions at other
times may vary or be different from those described in this report.
5.0 ENGINEERING EVALUATION & RECOMMENDATIONS
5.1 GENERAL DEVELOPMENT CONSIDERATIONS
The conclusions and recommendations contained in this report are based upon the data obtained
from the 37 test borings performed, laboratory testing, our past experience with similar type soils
and information provided regarding the proposed development. It is our opinion that the
subsurface conditions encountered on the project site project site are suitable for the proposed
development provided the recommendations presented in subsequent sections of this report are
followed throughout the design and construction phases of this project. If structural loading,
geometry, alignment or elevation of the structures differ from those outlined herein, or if the
conditions encountered during construction differ from those encountered at the soil test borings
performed by F&R, then F&R requests the opportunity to review the recommendations presented
herein based on the new information and make any necessary changes.
5.2 SITE PREPARATION
After clearing and grubbing, the entire building and pavement areas should be stripped of all
organic laden soils, high plasticity near-surface soils (if encountered), trash, debris and other
organic materials to a minimum of 10 feet beyond the structural and pavement limits including
beneath proposed slopes. Upon the completion of the stripping operations, the exposed subgrade
Town of Holly Springs 6 F&R Project No. H66-0986
Proposed Novartis Facility, Holly Springs, NC September 19, 2006
RING(
111
in areas to receive fill should be proofrolled with a loaded dump truck or similar pneumatic tired
vehicle with a minimum loaded weight of 20 tons. The geotechnical engineer or his/her
qualified representative should observe the proofrolling operation. Any areas that deflect, rut or
pump excessively during the proofrolling or fail to improve sufficiently after successive passes
they should be repaired as directed by the geotechnical engineer. Methods of repair may include
scarifying, drying and re-compacting, undercutting and replacement with approved structural fill,
and the use of geo-grid or other geotextile stabilization methods. After excavation of the site has
been completed, the exposed subgrade in cut areas should also be proofrolled. F&R
recommends that site grades be maintained to promote surface drainage away from structural and
paved areas and to reduce the potential for ponding water. Should the exposed subgrade soils
become excessively wet, our geotechnical engineer should be consulted for guidance.
Proofrolling should not be performed on saturated or frozen subgrades, or during inclement
weather conditions.
Based on the results of the soil test borings, we anticipate loose to very dense and stiff to very
hard Triassic soils will be encountered during general site grading as well as installation of
foundations and utilities for the proposed structures and parking and drive areas. We anticipate
that these soils can be excavated using pans, scrapers, backhoes and front-end loaders. It is also
anticipated that PWR or very hard materials will be encountered during site grading, foundation
construction or utility installation. The extent of PWR will depend on final site grades. Thirty of
the borings encountered PWR at depths varying from 3 to 35 feet below the surface.
Heavy excavating equipment with ripping tools (e.g., D-8 dozer with single shank ripper) is
typically effective in removing the softer PWR (i.e., PWR with SPT blow counts of 50/3" to 50/6")
during mass grading activities. Removal of harder PWR (i. e., PWR with SPT blow counts of 50/1"
to 50/3") during mass grading in open areas will not likely be possible with ripping equipment and
may require hammering, chipping or blasting. Removal of PWR from confined excavations (e.g.,
utility or foundation excavations) is typically more difficult than from large open mass excavations.
Removal of softer PWR, (i.e., PWR with N-values of (50/3" to 50/6") from confined excavations
(e.g., utility excavations) may be possible using a large track hoe (e.g., CAT 330 with rock teeth);
however, excavation will likely be slow and light blasting is typically performed to pre-loosen the
Town of Holly Springs 7 F&R Project No. H66-098G

1??1
PWR. Removal of harder PWR, (i.e., PWR with N-values of 5010" to 50/3") in confined
excavations will likely require blasting. The speed and ease of PWR excavation will depend upon
the equipment utilized, experience of the equipment operators and geologic structure of the PWR. It
should be noted that areas of difficult excavation materials might exist intermediate of the test
boring locations.
5.3 STRUCTURAL FILL PLACEMENT AND COMPACTION
Based on the results of our soil test borings, the on-site Triassic soils (ML, CL, SC and SM) may be
used as structural fill, providing these soils are at a moisture content that allow for "proper"
placement and compaction as recommended in this report. Material to be used as structural fill
should be tested prior to its use, to evaluate its suitability and compaction characteristics. If blasting
is required and the larger pieces of Triassic rock cannot be crushed with on-site compaction
equipment, then a rock crusher will need to be brought to the site. The crushed material should not
exceed 3 inches in size and should not contain more than 20 percent by volume particles greater
than 2 inches. The remaining soil portion of the crushed material shall have a gradation similar to
the over burden soils that are excavatable. Structural fill should be free of organic material and
other deleterious material.
In general, soils comprising the following ASTM classifications and having a Plasticity Index (PI)
of less than 25 can be used for structural fill: GW (well-graded gravels), GP (poorly-graded
gravels), GM (silty gravels), GC (clayey gravels), SW (well-graded sands or gravelly sands),
SP (poorly-graded sands or gravelly sands), SC (clayey sands), SM (silty sands), CL (sandy or lean
clays), or ML (sandy silts). Soils of high plasticity (CH clays & MH silts) should be used in non-
structural areas or in deep fills (greater than 5 feet) in parking and drive areas.
Representative samples of each engineered fill material should be returned to our laboratory and
tested to establish the material's moisture-density characteristics including, maximum dry density,
optimum moisture content, and plasticity index. Results from these tests will be utilized during
quality control of the structural fill and to determine if the fill material meets project specification
requirements. Backfill in structural areas should contain no more than 5 percent (by weight) of
organic material and should have a standard Proctor maximum dry density not less than 90 pounds
per cubic foot as determined by ASTM D 698. Soils not meeting these criteria may be used in
Town of Holly Springs s F&R Project No. H66-098G

F&
m
landscaped or non-structural areas.
The overburden soils on this site consist predominantly low to moderately plasticity silts and clays.
Based on our past experience, these soil types are generally considered to be fair to well suited for
use as structural fill material. However, these soils have sufficient silt and clay content to render
them moisture sensitive. These soil types can become unstable during normal construction traffic
and activities when wet. Ideally, earthwork operations should be performed during the seasonally
drier months (typically May to October) when the weather will generally be more conducive to
controlling and modifying the moisture content of the on-site soils. However, we understand that
earthwork construction may begin in October 2006 and extend through the seasonally wet times of
the year (typically November to April) which may result in difficulties in properly placing and
compacting the on-site soils, soft subgrade conditions, and possible undercutting in excess than
would otherwise be expected.
Once fill placement begins, F&R's personnel should perform field density tests to document the
degree of compaction obtained in the field by the contractor. Fill material should be placed in loose
lifts not exceeding 8 inches in thickness. The moisture content of the fill soils should be within
f3 percent of the fill's optimum moisture content. The in-place dry density of the compacted fill
should be at least 95 percent of soil's maximum dry density as determined by ASTM D 698, unless
otherwise specified. However, the upper 12 inches of finished subgrades within structural and
paved areas should be compacted to 100 percent of the same index. Monitoring of site preparation,
including fill placement and density testing by our engineering technician, is essential in verifying
that adequate compaction is being achieved by the contractor.
5.4 CUT AND FILL SLOPES
In general, permanent project slopes should be designed at 3 horizontal to 1 vertical (3H: IV) or
flatter. Steeper slopes may require reinforcement for stability purposes. The tops and bases of all
slopes should be located a minimum of 10 feet from structural limits. The fill slopes should be
adequately compacted, as outlined in this report, and all slopes should be seeded and maintained
after construction. If sloughing or erosion occurs, the use of a vegetation mat or geotextile and large
stone may be required to stabilize the slopes. A swale or ditch should be constructed near the top of
slopes to redirect surficial runoff away from the slope face.

Proposed Novartis Facility, holly Springs, NC September l9, 2006

M
tttl
It is F&R's understanding that 2H:1 V slopes are being considered on the north and south side of the
project site and may have a maximum height of 27 feet. F&R has evaluated a 30-foot high 2H:1 V
fill slope (north side of site) using on-site soils and soil strength parameters derived from triaxial
testing. Based on slope stability analyses (see Appendix C for analysis), a minimum factor of safety
of 1.6 was derived and geotextile reinforcement is not required to maintain stability. F&R has
provided a wrapped face design to reduce the potential for erosion of the slope face and possible
sloughing. The design and construction recommendations are included in Appendix C.
5.5 TEMPORARY EXCAVATIONS
Mass excavations and other excavations required for construction of this project must be performed
in accordance with the United States Department of Labor, Occupational Safety and Health
Administration (OSHA) guidelines (29 CFR 1926, Subpart P, Excavations) or other applicable
jurisdictional codes for permissible temporary side-slope ratios and/or shoring requirements. The
OSHA guidelines require daily inspections of excavations, adjacent areas and protective systems by
a "competent person" for evidence of situations that could result in cave-ins, indications of failure of
a protective system, or other hazardous conditions. All excavated soils, equipment, building
supplies, etc., should be placed away from the edges of the excavation at a distance equaling or
exceeding the depth of the excavation.
5.6 FOUNDATIONS
Based on the results of our soil test borings, the proposed structures can be supported on the low-
plasticity undisturbed Triassic soils or on newly placed structural fill, provided the
recommendations outlined in this report are implemented. A net allowable bearing pressure of up to
3,000 pounds per square foot (pso can be used for design of the foundations bearing on the
low-plasticity undisturbed Triassic soils, or on structural fill compacted to at least 95 percent of its
Standard Proctor Maximum Dry Density (ASTM D 698). If the foundation bearing elevation for
the Bulk Manufacturing Building 41 and the Finish/Fill Building #1 can be lowered to at least
elevation 335 feet, then a net allowable bearing pressure of 4,000 psf may be used for design of
those two structures. Some undercutting may be required in some of the foundation excavations if
incompetent bearing soils are encountered. Should a mat foundation system be chosen for support,
a modulus of subgrade reaction of 20 pci should be used for the bearing soils in conjunction with
Town of Holly Springs 10 F&R Project No. H66-093G
Proposed Novnrtis Facility, HollY Springs, NC September l9, ?006
iINCr
J
I??I
the above net allowable bearing pressures.
Exterior foundations should extend to a minimum depth of 18 inches below external grade for frost
protection. Deeper embedment depths may be required if unsuitable subgrade bearing material is
encountered once foundation construction begins. In addition, regardless of loading, continuous
wall and column footings should have minimum widths of 24 and 36 inches, respectively.
Adequately spaced control joints should be incorporated in the design of footings and masonry
walls at locations where any transition occurs between cut and fill areas. Other design
considerations should be dictated by building loads and local building code requirements.
Triassic soils are characteristically very susceptible to deterioration when exposed to the elements.
The foundation-bearing surface should be level or suitable benched and free of loose soil, ponded
water, and debris. If the bearing soils are softened by surface water intrusion or exposure, the
softened soils must be removed from the foundation excavation bottom immediately prior to
placement of concrete. Foundation excavations should be maintained in a dry condition throughout
the foundation construction process.
We recommend that the bearing surfaces be evaluated by F&R's geotechnical staff professional
prior to foundation installation. This evaluation may consist of performing hand auger borings with
Dynamic Cone Penetrometer (DCP) testing equipment or other suitable methods. Unsuitable soils
detected during this evaluation should be undercut as directed by our geotechnical engineer.
If the foundation excavations remain open for long periods of time, or during inclement weather, re-
evaluation of the subgrade materials by our geotechnical staff professional should be performed
prior to steel, concrete, or stone placement. We recommend that individual foundations be
concreted as soon after the evaluation as possible to minimize potential disturbance of the bearing
soils. If it becomes apparent that the foundation bearing soils will be exposed to inclement weather,
we recommend that the footings are over excavated 2 to 4 inches and a "mud seal" of lean concrete
is poured over the surface of the bearing material to prevent entry of rainfall and runoff water.
Based on the general stratigraphy in the proposed structural areas, our past experience with similar
projects, and the anticipated magnitude of the structural loads, F&R has estimated that maximum
total settlement of the proposed buildings will be less than approximately 1 to 1 '/4 inches and
differential settlements to be on the order of 1/2 to 1/4 inches if the recommendations presented herein
Town of Holly Springs 1 l MR Project No. H66-098G
Proposed Novnrtis Fncilily, Holly Springs, NC September 19, '006

are implemented and followed. Variations in the consistency of the soil will contribute to some
differential settlement of the foundations.

The building ground floors may be designed as a slab-on-grade. We recommend that a modulus
of subgrade reaction (k) of 175 pounds per cubic inch (pci) be used for slab design (structural
slabs should use k=20 pci). The subgrade soils for support of floor slabs should be prepared as
outlined in previous sections of this report. Utility and other construction excavations performed
in the prepared floor slab subgrade should be backfilled in accordance with previously
referenced structural fill criteria to aid in providing uniform floor support. The floor slab should
be supported on at least 4 inches of NCDOT No. 57 washed stone to provide a uniformly well-
compacted material immediately beneath the slab. All floor slabs should be underlain by a vapor
barrier to reduce the potential for floor slab dampness; all vapor barrier construction should be
performed in accordance with applicable ACI guidelines. Floor slab design and construction
should incorporate isolation joints around columns, utility penetrations, and along bearing walls
to allow for differential movement to occur without damage to the floor.
5.8 LATERALLY LOADED WALLS
It is our understanding that, laterally loaded dock retaining walls and pits are planned for this
project; however, all wall locations were not available at the time of this report. It is F&R's
understanding that these walls will be conventional cantilever walls constructed of cast-in-place
concrete.
Foundation construction for the retaining walls should be in accordance with the previous
foundation recommendations. The proposed cantilever retaining walls should be designed such
that the maximum foundation edge pressure does not exceed the previously recommended
allowable bearing capacity of 3,000 psf.
The composition of the cut soils on this site varies considerably. F&R recommends that the
retaining walls be backfilled with silty/clayey sand (SM and SC soils) or low plasticity sandy silts
and clays (CL and ML soils). F&R does not recommend that the retaining walls be backfilled

It11
with highly plastic clays or silts (CH and MH soils).
Laterally loaded walls that are permitted to rotate at the top, such as free-standing walls, may be
designed to resist active earth pressures using an active earth pressure coefficient (Ka) of 0.35.
F&R recommends that an active earth pressure EFW of 42 pcf be used in design if above
recommended soils are used for wall backfill. For sliding resistance along the base of the
foundation, a friction factor (tan 5) of 0.30 should be utilized. For cases where passive earth
pressure resisting forces are present, a passive earth pressure coefficient (Kp) of 1.35 can be used
in design where foundation faces bear directly against undisturbed stiff native soils or well
compacted structural fill; this coefficient incorporates a factor of safety of 2.0 to limit the amount
of movement needed to mobilize the passive resistance. Assuming an in-situ density of
approximately 110 pcf for native undisturbed soils, the passive earth pressure EFW would be 162
pcf. If the walls are not permitted to rotate at the top (like basement walls), Then the at rest earth
pressure coefficient (Ka) of 0.5 should be used resulting in an EFW of 60 pcf.
Lateral earth pressures arising from surcharge loading, foundations in the backfill zone,
earthquake loading and groundwater should be added to the above soil earth pressures to
determine the total lateral earth pressure, which the walls must resist. In addition, transient loads
imposed on the walls by construction equipment during backfilling should be taken into account
during design.
Compaction of backfill behind the walls should be on the order of 95 percent of the standard
Proctor maximum dry density in structural areas. In non-structural areas, backfill compaction
can be reduced to 92 percent. Excessive compaction may cause damage to the walls. Walls
should be adequately braced during compaction of the wall backfill. Heavy compaction
equipment should not be allowed within 5 feet of the walls.
We recommend that laterally loaded walls be provided with a drainage system to maintain the wall
backfill in a drained condition at all times such that the walls are not subject to hydrostatic
pressures. We recommend that a one-foot wide zone of free draining washed stone be constructed
adjacent to the back of the walls and extend down to a foundation drain (perforated drain pipe). A
geotextile filter fabric (Mirafi 140N or equivalent) should be placed between the washed stone

drainage layer and the remaining backfill material. The foundation drain should be positively
graded to allow drainage of any water that may collect in the wall backfill. An alternative to using
a stone drainage layer would be to use a geo-composite drainage material such as Miradrain 6000.
The drainage material should extend along the full height of the wall and down to the foundation
drain.
5.9 SEISMIC DESIGN CRITERIA
F&R has evaluated the data obtained from the soil test borings performed with regard to the
International Building Code (IBC) for assignment of Seismic Site Classification of this site. A
weighted average of the conditions in the upper 100 feet of the site was performed with the
assumption that hard to very hard and dense to very dense soils (50 < N < 100 blows per foot or
better) are present below the depth of our exploration. Based upon the subsurface conditions
encountered and proposed grades, The Bulk Manufacturing Building #1, Fill/Finish Building #1 and
the Lab immediately north of those two structures has an IBC Site Classification of C and all
remaining structures have a Site Classification of D.
5.10 PAVEMENTS
Subgrade preparation in paved areas should also be performed as outlined in previous sections of
this report, including proofrolling of subgrade and base course materials. Exposed pavement
subgrades should be re-compacted to at least 100 percent of the standard Proctor maximum dry
density just prior to base stone placement.
To provide a better estimate of soil subgrade support, four representative bulk samples of near-
surface soil were obtained from the project site and subjected to standard Proctor and CBR
testing (see laboratory testing results in Appendix Q. The samples consisted of low plasticity
silts and clays with varying amounts of sand (USCS - CL and ML soils). Typical published CBR
values for these materials range from 5 to 15. It has been F&R's experience that CBR values of
less than 5 to 8 are typical in this area for these soils types. The laboratory testing indicated CBR
values of 0.2 to 4.9, which is in the lower range of values for these soil types. Based on the
results of the laboratory testing and our experience with similar soils on many projects, F&R
recommends that a CBR value of 3 be used for pavement design.

For the purpose of evaluating the proposed pavement sections on the project, a traffic volume
equal to approximately 87.5 daily 18-kip equivalent single axle loads (ESALs) was used for the
site roads, which is based on a traffic volume of 50 trucks per day per lane (AASHTO H20-S16
tandem axle loads). A traffic volume of 1 ESAL was used for the parking lots, which is based on
1000 cars per day and no truck traffic. As requested, F&R's pavement design evaluation was
based on a 10-year design life. Based on the traffic volume and design life information provided
by Jacobs and subgrade support conditions, we recommend the following flexible pavement
sections over a prepared subgrade:

* Use NCDOT Asphalt surface type SF9.5A for Light Duty and S9.513 for Heavy Duty
The geotechnical investigation requirements provided by Jacobs requested that the geotechnical
engineer identify areas that would require soil stabilization to improve the CBR, if the CBR is 4
or less. Since the borings were relatively widely spaced and the specific subgrade conditions are
not known at this time, it is F&R's opinion that a majority of the on-site soils will on average
have CBR values of less than 4. In this area, pavement subgrade stabilization could be
performed by lime or cement stabilization of the upper 8 inches of the subgrade. The method of
stabilization (cement or lime) should be determined once the specific subgrade materials are
known. If pavement subgrade stabilization is pursued, F&R can provide revised pavement
section designs.
We recommend that rigid concrete pavement be utilized in loading dock areas, dumpster areas or
other area subjected to concentrated loading. The concrete pavement should consist of at least 7

inches of 4,000 psi air-entrained concrete overlying a 6 inch thick base course of compacted
ABC stone.
We emphasize that good base course drainage is essential for successful pavement performance.
The ABC stone should be maintained in a drained condition at all times. Water build-up in the
base course could result in premature failures. Proper drainage may be aided by grading the site
such that surface water is directed away from pavements and construction of swales adjacent to
pavements. All pavements should be graded such that surface water is directed towards the outer
limits of the paved area or to catch basins located such that surface water does not remain on the
pavement.
Flexible asphalt pavements, concrete pavements, and bases should be constructed in accordance
with the guidelines of the latest applicable North Carolina Department of Transportation
Standard Specifications for Roads and Structures. Materials, weather limitations, placement and
compaction are specified under appropriate sections of this publication. Concrete pavement
design and construction should be in accordance with applicable American Concrete Institute
(ACI) guidelines.
5.11 CORROSION POTENTIAL
F&R performed a preliminary evaluation of soil corrosivity at this project site with respect to
potential effect on underground utilities and concrete. F&R subjected four representative soils
samples to pH, Chloride, Resistivity and Sulfate analysis. The results are presented in the following
table and are included in Appendix C.

Based on the results of the laboratory testing and comparison with the 10-point scale to
determine the corrosion potential to steel pipe (as presented in the Handbook of Ductile Iron
Pipe), it does not appear that corrosion protection is necessary for underground steel piping at the
project site. This is based primarily on the relatively neutral pH, high resistivity and good
overall site drainage that will be present at the site. Based on the relatively low sulfate
concentrations and comparison with PCA guidelines, the soils on this site appear to pose a low
risk for sulfate attack of buried concrete. Overall, it is F&R's opinion that this site has a low
potential for corrosion of buried utilities and concrete. It should be noted that F&R evaluation
does not consider stray electrical currents or certain industrial processes that could affect soils
corrosivity potential.
6.0 CONSTRUCTION QUALITY CONTROL
As previously discussed, the Geotechnical Engineer of record should be retained to monitor and test
earthwork activities, and subgrade preparations for foundations, floor slabs and pavements. It
should be noted that the actual soil conditions at the various subgrade levels and footing bearing
grades will vary across this site and thus the presence of the Geotechnical Engineer and/or his
representative during construction will serve to validate the subsurface conditions and
recommendations presented in this report. We also stress the importance of conducting hand auger
and DCP testing in the footing excavations in order to confirm the anticipated subsurface conditions
and define footings that should be undercut and repaired as outlined in this report.

Geolechnical Engineering Report
Geotechnical Services Are PeMormed for
SpecMc Purposes, Persons, and Projects
Geotechnical engineers structure their services to meet the spe-
ctftc needs of their clients. A geotechnlcal engineering study con-
ducted for a civil engfineer may not fulfill the needs of a oonstruc-
tion contractor or even another civil engineer. Because each geot-
echnical engineering study is unique, each geotechnical engl-
neering report Is unique, prepared solely for the client. No one
except you should rely on your geotechnkal engineering report
without first conferring with the geotechnkal engineer who pre-
pared It. And no one--not even you--should apply the report for
any purpose or project except the one originally contemplated.
Read the M Report
Serious problems have occurred because those relying on a
geotechnical engineering report did not read it all. Do not rely
on an executive summary. Do not read selected elements only.
A Geotechnical Engineering Report Is Band on
A Unique Set of Project-Specific Factors
Geotechnical engineers consider a number of unique, project-spe-
cifk factors when establishing the scope of a study. Typical factors
include: the client's goals, objectives, and risk management pref-
erences; the general nature of the structure Involved, its size, and
configuration; the location of the structure on the site; and other
planned or existing site Improvements, such as access roads,
parking lots, and underground utilities. Unless the geotechnical
engineer who conducted the study specificalry, indicates other-
wise, do not rely on a geotechnical engineering report that was,
• not prepared for you,
• not prepared for your project,
• not prepared for the specific site explored, or
• completed before Important project changes were made.
Typical changes that can erode the reliability of an existing
geotechnical engineering report Include those that affect:
• the function of the proposed structure, as when
it's changed from a parking garage to an office
building, or from a light industrial plant to a
refrigerated warehouse,
• elevation, configuration, location, orientation, or
weight of the proposed structure,
• composition of the design team, or
• project ownership.
As a general rule, always inform your geotechnical engineer
of project changes--even minor ones-and request an
assessment of their impact. Geotechnical engineers cannot
accept responsibility or liability for problems that occur
because their reports do not consider developments of which
they were not informed.
Subsurface Conditions Can Change
A geotechnical engineering report is based on conditions that
existed at the time the study was performed. Do not rely on a
geotechnical engineering report whose adequacy may have
been affected by: the passage of time., by manmade events,
such as construction on or aclacent to the site; or by natural
events, such as floods, earthquakes, or groundwater fluctua-
tions. Always contact the geotechnical engineer before apply-
ing the report to determine if it Is still reliable. A minor amount
of additional testing or analysis could prevent major problems.
Most GeotechnIcal Findings Ape
Professional Oplnlons
Site exploration identifies subsurface conditions only at those
points where subsurface tests are conducted or samples are
taken. Geotechnical engineers review field and laboratory data
and then apply their professional judgment to render an opinion
about subsurface conditions throughout the site. Actual sub-
surface conditions may differ-sometimes signfficant"om
those Indicated in your report. Retaining the geotechnical engi-
neer who developed your report to provide construction obser-
vation Is the most effective method of managing the risks asso-
clated with unanticipated conditions.
A Report's RecoinimbIlMs Apo Not Mal
Do not overrely on the Construction recommendations included
in your report. Those recommendations are not final, because
geotechnical engineers develop them principally from judgment
and opinion. Geotechnical engineers can finalize their recom•
mendatlons only by observing actual subsurface conditions
revealed during construction. The geotechnical engineer who
developed your report cannot assume responsibility or liability for
the report's recommendations if that engineer does not perform
construction observation.
A Gootochnical Engineering Report Is 8ubled
To WdOrpretatlon
Other design team members' misinterpretation of geotechnical
engineering reports has resulted in costly problems. Lower
that risk by having your geotechnical engineer confer with
appropriate members of the design team after submitting the
report. Also retain your geotechnical engineer to review perti-
nent elements of the design team's plans and specifications.
Contractors can also misinterpret a geotechnlcal engineering
report. Reduce that risk by having your geotechnical engineer
participate in prebid and preconstruction conferences, and by
providing construction observation.
Do Not Redraw the Engineer's Logs
Geotechncal engineers prepare final boring and testing logs
based upon their Interpretation of field logs and laboratory
data. To prevent errors or omissions, the logs Included In a
geotechnical engineering report should never be redrawn for
Inicluslon In architectural or other design drawings. Only photo-
graphic or electronic reproduction is acceptable, but recognize
that separ&ing logs from the report can elevate risk.
Give Contractors a Conpiete
Report mind Gddance
Some owners and design professionals mistakenly believe they
can make contractors liable for unanticipated subsurface condi-
tions by limiting what they provide for bid preparation. To help
prevent costly problems, give contractors the complete geotech-
nical erlglneedrlg report, but preface it with a dearly written let-
ter of transmittal. In that letter, advise contractors that the report
was not prepared for purposes of bid development and that the
report's accuracy is limited; encourage them to confer with the
geotechnical engineer who prepared the report (a modest fee
may be required) and/or to conduct additional study to obtain
the specific types of Information they need or prefer. A prebld
conference can also be valuable. Be sure contractors have wM
clent time to perform additional study. Ony then might you be In
a position to give contractors the best information available to
you, while requiring them to at least share some of the financial
responsibilities stemming from unanticipated conditions.
Read ResponslbMty Provisions Closely
Some clients, design professionals, and contractors do not
recognize that geotechnical engineering is far less exact than
other engineering disciplines. This lack of understanding has
created unrealistic expectations that have led to disappoint-
ments, claims, and disputes. To help reduce such risks, geot-
echnlcal engineers commonly Include a variety of explanatory
provisions In their reports. Sometimes labeled `limitations",
many of these provisions indicate where geotechnlcal engi-
neers responsibilities begin and end, to help others recognize
their own responsibilities and risks. Read these provisions
closely. Ask questions. Your geotechnical engineer should
respond fully and frankly.
Geonviromnental Concerns Are Not Covered
The equipment, techniques, and personnel used to perform a
geoenvtronmental study differ significanty, from those used to
perform a geotechnical study. For that reason, a geotechnieal
engineering report does not usually relate any geoenvironmerv
tal findings, conclusions, or recommendations; e g., about the
likelihood of encountering underground storage tanks or regu`
Iated contaminants. Unanticipated environmental problems have
led to numerous protect failures. If you have not yet obtained
your own gecenvironmentai information, ask your geotechnloal
consultant for risk management guidance. Do not rely on an
environmental report prepared for someone else.
Rely an Your Geotechnkal Engineer for
Additional Asslstanire
Membership In ASFE exposes geotechnical engineers to a wide
array of risk management techniques that can be of genuine ben-
efit for everyone Involved with a construction project. Confer with
your ASFEanember geotechnical engineer for more Information.

SPLIT SPOON SAMPLING
The borings were made in accordance with ASTM Specifications D-1586. The borings were advanced
using either hollow stem augers or the rotary drill method using a bentonite slurry. The drill method
employed depends upon the subsurface conditions and our experience in the general area. After cleaning
all loose cuttings from the boring, the soil is sampled with a split barrel sampler. The sampler is driven to a
depth of 18 inches or to a blow count of 100 blows with a 140-pound hammer falling 30 inches. The
number of blows required for driving each 6-inch increment is recorded. The first 6-inch increment is
required to seat the sampler below the disturbed zone, the second and third increments are added to yield
blows per foot. This value is the standard penetration resistance, N. This is recorded on the attached logs
of borings per each 6-inch increment of penetration. The "N" value, when properly evaluated, is an index to
the in-place density strength and foundation support capacity.
Representative portions of each soil sample, obtained from the split tube sampler, were placed in glass jars,
sealed and transported to our Raleigh, North Carolina laboratory. The soils are classified in accordance
with ASTM Specification D-2488, "Visual--Manual Classification of Soils for Engineering Purposes",
based on the Unified Classification System. The Unified Group Symbol is shown on the logs for each
distinct stratum, and is described briefly on the attached chart.

PARTICLE SIZE ANALYSIS OF SOILS
Purpose: The grain size data are often used to aid in the classification of soils and in the estimation
of properties such as permeability, compressibility and strength.
Procedure: The test samples can be prepared using either the dry method or wct method as
described in the various references. After preparation, the lest can be divided into two parts, the
detemlination of the size and distribution of the coarse fraction and the determination of the size
distribution of the fines. The division between the two tests is the No. 200 sieve. The coarse
fraction is tested using the sieve method whereas the fines are tested using the hydrometer method.
If both tests are performed, the test is referred to as the combined malysis.
In the sieve analysis of the coarse fraction, the soil is passed through a series of sieves, and the
weight retained on each sieve is detcrnimed. The distribution of weights is then computed and the
percent passing is plotted for display.
In the hydrometer method, the particle sire is determined by Stoke's equation. The soil is mixed in
a heavy slurry and the rate of sedimentation is measured with hydrometer. This data can then be
reduced to a distribution of particle sire and percent Imer as in the sieve analysis.

Particle Size Analysis and Determination of Soil Constants."

ATTERI3ERG LIMITS
Purpose: Atterberg limits tests (liquid and plastic limits) are perlonned to detemilne the soil
classification and plasticity properties of the soil specimen. These properties can he
correlated with approximate values for compressibility, strength, shrinkage (swell) and
permeability.
Procedure: The liquid limit of a soil is Qle water content. expressed as a percentage of the
,weight of the oven dry soil, at the boundary between the liquid and plastic stales. The plastic
limit is the water content expressed as a percentage of the weight of the oven dry soil, at the
boundary between the plastic and semi-solid states. The difference between these two values
is the Plasticity Index (PI).
The liquid limit is determined by obtaining the water content at which the soil will flow under
a specified dy-namic force. The soil is wetted, placed in a special liquid limit device and
?,rooved into two halves, The device is then dropped a specified distance ?5 times. The
liquid limit is defined as the water content at wbich the two halves will flow together over a
specified distance.
The plastic limit is determined by obtaininu the water content at which the soil can he rolled
into thin threads by hand, on a ground-glass or non-absorbent paper. The plastic limit is
defined as the moisture content at which the soil cannot be rolled into threads smaller than
1 /8 Inch in dlanlcter.

Limit. Plastic limit and Plasticity lade\ or Soils."

MOISTURE CONTENT
Purpose: The purpose of the moisture content test is to detemiine what percentage of the
weight of a given soil is water as opposed to the weight of solid particles of the soil sample.
This pcreentage in the case of in-situ soils indicates the extent to which the soil in question is
saturated. For controlled till placement the moisture content is critical in achieving
maximum compaction.
Procedure: A sample ol'soil is weighed in the wet condition, then placed in a drying oven
and is dried to constant weight. The dry weight is then determined. The noisturc content in
percent is the ratio of the weight of moisture to the weight of dry soil multiplied by 100,

Determination of Moisture Content of Soil.

MOISTURE.-DENSITY (STANDARD)
Purpose; The moisture-density relationship of a givcn soil is deterntirIed using a specified
compaclive effort, to provide a standard unit weight against which achieved field compaction
can be compared. The maximum dry unit weight obtained in this test is considered 100
percent of the standard Proctor density that can be obtained in a given soil.
Procedure: The standard Proctor test is performed on representative selected soil sampics.
The prepared soil is compacted in a cylindrical mold (with collar attached) in three equal
layers to give a total compacted depth of about 5 inches. Each layer is compacted by
uniformly distributed blows from a sliding weight rammer (5.5 pounds with 12-inch free
fall). The moisture content is increased about 2% and the above procedure is repeated until
there is a decrease or no change in the wet unit'A'cight. The maximum unit weight obtained
is determined and the corresponding moisture content (optimum moisture) is noted.

Density Relations of Soils Using 5.5 Ib. (2.5 Kg) Rammer and 12-inch

UNDISTURBED SAMPLING
Under certain circumstances sonic soils require rather precise laboratory testing. Samples
taken by split spoon are adequate for visual classification, but are not sufficiently intact For
quantitative laboratory testing. Relatively undisturhed samples are ohtained by forcing
Sections of O.D., lb gauge steel tubing (thin-wall or Shelby tubing) into the soil at desired
sampling levels. This sampling procedure is described by ASTM D-15$7, "Standard Method
Ibr Thin-Walled Tube Sampling of Soils."
%Vhcn Undisturbed samples are indicated in the drilling operation, the sampler is introduced in
the bore hole and hydraulically forced into the soil a distance of approximately 2 feet. The
tube is rotated to shear the sample and then is withdrawn. The sample is scaled in the tube
with wax, labeled, and shipped intact to our Raleigh, North Carolina laboratory.
Samples are removed (Irom the tube by a hydraulically operated extrusion press, measured,
sampled for moisture, and subjected to the appropriate test sequence.

TRIAXIAI. TEST
Purpose: The triaxial test is performed to determine the angle of internal friction (? ), cohesion and
shear strength ofcoliesive soils.
Procedure: 'triaxial tests on undisturbed soils samples may be:
i ) unconsolidated undrained, "W'2) consolidated undrained, "CU", or 3) consolidated drained,
"CD". The type of test performed is selected to best represent the field conditions. Back pressure
to cnsurc complete saturation and pore water pressure readings may also be taken in order to
determine the effective stresses and angle of shear resistance,.
For example, a "CU" test with pore pressure would consist of preparing at least three Undisturbed
samples from a 3" O.D. Shelby tube. Each sample is placed in the triaxial chamber and saturated
by confining with an all-around pressure m. After saturation is complete, the specimen is
consolidated at a selected confining pressure. Once the specimen has consolidated under the
confining pressure, the axial load is applied until the sample is sheared. [Pore pressure readings are
recorded as the axial load is applied.] The a; pressure is increased for each specimen and the test
results arc represented by a plot of shear stress versus axial stress (Mohr Circle Diagram).
The testing procedure is similar for the other two test methods; however, the actual procedures
differ as the name ofthe test method implies.

CALIFORNIA BEARING RATIO
Purpose: The California Bearing Ratio test is performed on subgrade, subbase and base course
materials to provide supporting values of various roadway materials which can be used as a basis
for pavement design.
Procedure: A sample of the subgrade soil is compacted in a cylindrical mold to the density and
moisture anticipated in actual constnrction. Cohesive soils arc allowed to soak, immersed in Nvater
for 96 hours. By means of a hydraulic jack, it penetration "needle" is forced into sample at a
controlled rate. Load valucs and corresponding, strain or dcl'ot7mation are noted. The ratios of the
load valucs in pounds per square inch at 0.1 inch and 0.2 inch penetration respectively arc
compared to the standard loads of 1000 and 1500 pounds per square inch respectively. (Tile latter
are those loads required to produce the same penetration in a compacted limestone sarnpic.) The
CBR in percent is the ratio of the loads at 0.1 penetration multiplied by 100.

Mirafi® MMESH
Introduction
Mirafi® MMESH is composed of green high-tenacity monofilament polypropylene yarns that
are woven together to produce an open mesh biaxial geotextile. Mirafi® MMESH is
specifically designed for secondary reinforcement and surface erosion protection for
steepened slope and retaining wall applications. Mirafi® MMESH allows for vegetation
growth, while holding back soil at the face.
In wrapping the face of a retaining wall with Mirafi® MMESH, removable facing supports
(e.g. wooden forms) or left-in-place welded wire mesh forms are typically used. The
recommended maximum vertical spacing between lagers of Mirafi® MMESH is 18 inches
(450 mm). The following figure shows a typical Mirafi MMESH vegetated wall/slope.

Vegetated Vertical Steps with Welded Wire Mesh or Wooden Formwork
In assessing these two facia options, there are several considerations. For instance, using
a wire mesh face support will typically result in higher material costs, yet lower labor costs
than using temporary wooden formwork. However, the wire mesh may provide additional
long-term face protection from ultraviolet light degradation and potential vandalism.
Further, the use of temporary wooden formwork will require access from the exterior of the
slope/wall face in order to insert and remove forms.
Inspection
The owner or the owner's engineer is responsible for certifying that the contractor meets all
the requirements of the specification, including material submittals and proper installation
of the geosynthetic reinforcements. The Contractor shall check the geosynthetic upon
delivery to ensure that the proper material has been received during all periods of
shipment and storage.
All geosynthetic materials shall be protected from temperatures greater than 1400F, and all
deleterious material that might otherwise become affixed to the geosynthetic and adversely
affect its performance.
Site Preparation
The foundation soil shall be excavated to the line and grades as shown on the construction
drawings or as directed by the Project Engineer. Over-excavated areas shall be filled with
compacted backfill material as per project specifications or as directed by the Engineer.
As a minimum, foundation soil shall be proof rolled and level prior to backfill and
geosynthetic placement. This exercise should be performed prior to each subsequent
geosynthetic layer installed.
Placement of Drainage Materials
Perforated schedule 40 or equivalent pipe, surrounded in drain rock, and wrapped in
geotextile, may be placed at the base of the wall/slope as shown on the Construction
Drawings. The pipe shall be laid at a minimum longitudinal gradient of 1 %. The pipe shall
be connected to the specified outlets with T-connectors. Outlet pipes, which pass through
the base of the wall facia, shall be wrapped with a geotextile to prevent loss of infill
materials. Outlet pipes shall be connected to the site drainage system or discharged in front
of the wall in a manner that will not cause surface erosion. Compact all fill placed against
the drainage system.
Placement of Welded Wire Mesh Facia
Place the wire baskets adjacent to one another at the elevation shown on the plans. Ties
may be used to keep wire baskets aligned. Note: the first two vertical rows of welded wire
baskets may be pushed forward during compaction of the backfill (It may be necessary to
adjust their setback or install vertical braces along the proposed alignment of the wall facia
at a minimum spacing of 60 inches center to center).
Geosvnthetic Reinforcement Placement
The geosynthetic reinforcement (Miragrid of Mirafi® PET fabric) shall be laid at the proper
elevation and orientation as shown on the construction drawings or as directed by the
Engineer. Correct orientation of the geosynthetic shall be verified by Contractor. The
geosynthetic shall be cut to length as shown on the construction drawings using a razor
knife, scissors, sharp knife, or equivalent.
The geosynthetic reinforcement leading edge shall be placed up to the front of the welded
wire mesh form and tensioned by hand until taut, free of wrinkles and lying flat. Adjacent
geosynthetic panels, in the case of 100 percent coverage in plan view, should be butted up
to one another, as necessary to ensure 100 percent coverage, unless otherwise specified
on the construction drawings. The geosynthetic reinforcement and Mirafi® MMESH may
need to be slit (perpendicular to the wall face) to stagger the wire basket support struts.
Geosynthetic panels may be secured in-place with staples, pins, sand bags, or backfill as
required by fill properties, fill placement procedures, or weather conditions, or as directed
by the Engineer.
The geosynthetic may not be overlapped or connected mechanically to form splices in the
primary strength direction. Single panel lengths are required in the primary strength
direction. Therefore the geosynthetic should be installed in one continuous piece with the
primary strength direction extending the full length of the reinforced area. No overlapping is
required between adjacent rolls unless specified by the Engineer.
Mirafi® MMESH Placement
Install Mirafi® MMESH parallel to the wall/slope face, or as directed by the project
engineer. Place the Mirafi® MMESH GR against the inside front face of welded wire mesh
form with 4' of embedment. When placing the Mirafi® MMESH, drape the geotextile over
the wire face, allowing for the required wrap embedment (typically 2.5'). Install the
reinforcing struts at 24 inch center to center (typical).

Place only the amount of geosynthetic required for immediately pending work to prevent

shall be placed, compacted and prepared as appropriate. After the specified soil layer has
been placed, the next geosynthetic layer and/or facing unit shall be installed. Mirafi®
MMESH should be seeded/vegetated as recommended by the project engineer.
Fill Placement
Fill should be placed in 6-8 inch thick lifts near the face of the wire baskets and then
proceed toward the tails of the Mirafi® MMESH and Geosynthetic reinforcement to help
tension the grid/fabric.
Backfill material shall be compacted to a minimum 90% modified proctor or as directed by
the project engineer. Backfill shall be placed, spread and compacted in such a manner as
to minimize the development of wrinkles in and/or movement of the geosynthetic. Backfill
shall also be placed in such a manner as to minimize the disturbance and/or the
misalignment of the wall facing. A minimum fill thickness of 6 inches is required prior to
the operation of tracked vehicles over the geosynthetic.
Turning of tracked vehicles should be kept to a minimum to prevent tracks from displacing
the fill and damaging the geosynthetic. Rubber tired equipment may pass over the
geosynthetic reinforcement at low speeds, less than 5 mph. Sudden braking and sharp
turns shall be avoided. Any geosynthetic damaged during installation shall be replaced by
the Contractor.
Backfill within 3 ft. of the wall/slope face will typically be compacted with hand equipment.
Density tests shall be made every lift or as directed by the Project Engineer. Backfill shall
be graded away from the wall crest and rolled at the end of each work day to prevent the
freezing and/or the ponding of water on the surface of the reinforced soil mass. The site
shall be maintained to prevent the flow of water from adjacent areas from entering the wall
area from overtopping the retaining wall during construction and after the completion of the
wall.
Seed Placement While Backfilling
Mirafi® MMESH is manufactured with an open weave that holds soil in, but allows
vegetation to grow through it. A mix of seed (optional if hydroseeding) and topsoil be
placed directly against the Mirafi° MMESH fabric face for each lift, as shown below.

Hydroseeding/ Hydromulching Wall Face
To vegetate the wall by hydroseeding, the welded wire baskets should be set back with a
4" (typical) offset at each lift, as shown below. This results in an overall batter of 781.
Each 4" shelf will create a flat surface for vegetative growth. The face should be
hydroseeded during the local growing season. The face should be watered prior to
hydroseeding. An irrigation system and maintenance program may be needed -
depending on local climate and environmental conditions.

Seed Selection

Seed performs best when planted during spring or early autumn.
Three general climate zones are shown below. Areas in the cool climate zone use cool
season grasses. Areas in the warm climate zone use warm climate grasses. The
transition zones typically use a mixture of both cool and warm season grasses, but
generally favor cool climate grasses more. Local suppliers generally have excellent
knowledge of seed selection for their local climate and environment.

Live Staking
Live staking may be performed with the Mirafi® MMESH /wire mesh facia. Live stakes are
woody stem cuttings of plants that root easily. Live stakes should be taken while a plant is
dormant (before spring) and planted directly into the face of the wall/slope. Live stakes
should be spaced 2 - T apart in all directions. Installation of live stakings should be
performed between the fall and early spring, while the plants are still dormant. Live staking
should be performed only in very moist environments or with plants known to survive in the
local environment.

RE: Germination Enhancement Testing of Slope Facing Geosynthetics
(Log # E2213-33-08 & E2193-34-07)
Dear John:
TRI appreciates the opportunity to provide testing services, including preparing and testing
vegetated facing systems composed of various products and welded wire facing. Following is a
summary of the testing strategy employed and a review of the test results.
STRATEGY
A bench-scale performance-related index test has been developed by the Erosion Cotnrol
Technology Council (ECTC) to examine the ability of a rolled erosion control product (RECP) to
enhance seed germination and initial vegetation growth. TRI has modified the test method for
near-vertical slope facing systems while generally following soil and seed preparation and
exposure condition conditions in the original test method.
TESTING APPROACH
The lab constructed 18" tall x 24" wide facing sections following the schematic below. Three
replicate boxes were constructed for each facing system. The boxes were maintained in an
environment of 72°F & 45%RH and watered weekly. Vegetative density measurements were
made at 30 and 60 days. Facing materials were installed with the cross-machine direction yarns
or ribs in the vertical direction directly up against the basket. When used with an erosion control
blanket, facing material was installed against the wire basket face with the erosion control
blanket between the soil and the grid.
