De�r iVLt. Greene:
l.� � � � �1
Falcon Engineering, Inc. (Falcon) is pleascd to present our proposal for Geotcchnical Engineering Services for the
above referenced project.
PROJECT DESCRIPTION
Tl�e following information will serve as the basis for d�e development of d�e Geotcchnical scope and fee for this
project:
➢ Stantec will be the Client in Charge. NCDOT Highway Division 3 will be the project owner. NCDOT
Geotechnical �ngineering Unit (G�� will provide input/review on the project.
➢ The project is being contiacted through the �astern Region Planning and Design On-call Contract. Falcon
�ngineering is Stantec's sole Geotechnical Services provider on that contract.
➢ Due the project volume and schedule, I�alcon has agreed to woxk alongside a second Geotechnical
Scrvices tirm for this assignment.
➢ Based on pro3imity�, capability, and ezisting worl�ing relauonships, Stantec and Falcon have agreed that
Catlin Engine�rs and Scientists �vi11 also provide Geotechnical Services on this projcct.
➢ Falcon and Catlin �vill both hold separate subcontracts with Stantcc, undcr the Primc Agreement with
NCDOT Highway Division 3.
➢ Falcon and Catlin have been provided preliminar�r plans in PDF rollplot and Microstation .dgn formats,
including preliminar�� profiles.
➢ R-3300A and R-3300B are being combined to be designed and bid on a common schedule. The combined
projcct currcntly includcs thc following:
■ 12.3 miles of new alignment median divided bypass highway, conunuing from the end of
proposed TIP project U-4751 (Military Cutoff Road) along US 17 B��pass (John Jay Burney Jr
Frcewa}'), to US 17 north of Hampstead, NC, near thc intcrscction witl� Long Leaf llrivc.
■ Three tull interchanges and one half interchange. Various Y-line adjustments, ramps, loops, and
services roads totaling over 25 nvles of alignment (including the mainline).
■ Siateen (16) bridge st�-uctures, including duals (each listed as a single bridge), water crossings,
grade separations, and fly�overs. Some currently unidentitted bridges ma5� include mechanically
stabilized earth (MSE) abum�ent retaining walls. Abtiitment retaining walls are not included in the

%
scope and fee at this time, however our experience is that abutment walls are typically employed
to reduce the number of spans on a given structure, and in that case could likely be
accommodated within the proposed fee estimate.
Six (6) reinforced concrete box culverts (RCBC).
No retaining walls, sound barrier walls, or other project elements not referenced herein are
included in the project at this time.
DIVISION OF GEOTECHNICAL SERVICES
Based on proximity, individual strengths and skillsets of the respective Geotechnical firms, availabiliry of
equipment and personnel, and other considerations, it has been agreed to that Catlin will perform Geotechnical
Services for all roadway components, and Falcon will perform Geotechnical Services for all structural components.
For contractual purposes, we understand the "A" and "B" sections are to be scoped and esrimated separately.
Therefore each firm will generate two (2) separate fee estimates and delineate scope items for the two TIP projects.
Although Falcon and Catlin will maintain separate scope and fee estimates, we intend to maintain a collaborative
working relationship, share data, take advantage of efficiencies wherever possible, and leverage each other's skills
to execute the work diligendy. For the purposes of generating scope and fee estimates to serve as a contractual
basis with Stantec, the following delineations of scope are provided:
➢ Falcon will be responsible for performing all borings for bridges.
➢ Catlin will be responsible for performing all borings for roadways and culverts.
➢ Each firm will be responsible for stakeout, utiliry location, and obtaining coordinates and elevations for
their respective borings.
➢ Each firm will perform the necessary laboratory testing on samples from their respective borings.
➢ The firms will provide completed gINT logs with Northing, Easting, and Elevation to each other in areas
where work overlaps. Specifically, Catlin will provide Falcon with borings in the pro�mity of each culvert,
and Falcon will provide Catlin with all bridge borings to inform the delineation of stratigraphy for the
nearby roadway alignments.
➢ Due to the fact that Catlin will be traversing all alignments with clearing and drilling equipment, it is most
efficient for Catlin to provide clearing to most or all of Falcon's borings. Falcon and Catlin will coordinate
for boring stakeouts to occur roughly concurrently so as to facilitate clearing access. In the event that
Catlin will not be preparing access trails within relatively close distance of Falcon's borings, or Falcon's
bridge borings are not staked in time for Catlin's clearing crew to accommodate, Falcon will provide
supplemental clearing. Some supplemental clearing is included in Falcon's estimate for borings in wooded
areas.
➢ If additional opportunities arise for the firms to gain efficiencies in project budget or schedule, we intend
to leverage those opportunities to the full extent, provided accommodate the partner firm does not
become a hindrance.
➢ Additional work sharing may occur depending on a variety of factors at the time the work is executed,
including but not limited to: providing field staff and/or equipment for each other's respective scopes,
performing lab testing on each other's respective samples, or assisting with data processing, drafting, or
Engineering tasks for each other's respective project elements. Any such work sharing will be coordinated
between Falcon and Catlin via a separate agreement, in order to maintain clear contractual agreements
with Stantec.

PROPOSAL FOR GEOTECHNICAL SERVICES �
FALCON'S SCOPE OF SERVICES
Our scope of geotechnical services will include the tollowing elements.
Structure (Bridge) Investigation
Falcon will perforin Structure Subsurface In�restigations in general accordance �vith NCDOT GEU guidelines. At
least one (1) boring �vill be drilled within the closest proYimity reasonably possible to each bent location. ror
bridges exceeding 60 feet in width, two (2) borings will be drilled per bent, one near each end of the bent. Bridge
borings are generally anticipated to Ue drilled to an average depth of 60 to 80 feet. Prior experience from the
iVlilitaiy Cutoff Road (LT-4751) project indicates the likely presence of relativelv shallow limestone at the southern
end of the project. Published �eologic information reviewed Uy� Falcon indicates the same geologic formation e�ists
beneath the entirety of the project, along with the possibility of solution cavities (vo.ids). We anticipate driven pile
foundations at all end bents, driven piles on footings at grade separation interior Uents, and driven pile bents or
drilled piers at water crossing interior bents. Depending on the depth of limestone, overlying materials, foundation
type, and hardness of the limestone at each bridge location, some rock coring is likely to be required to provide
adequate foundation design input. Coring is generally anticipated for end bent Uorings only, unless very shallow
limestone is encountered. Based on the structure summary provided by Stantec, we anticipate the following
borings will be performed for each stnicttire.

Falcon will contact the North Carolina One Call Center (NCOCC) to request the location of subscriber utilities in
the viciniry of the proposed boring locations. We will also coordinate with local municipal water and sewer districts
to identify and locate utilities in the area if needed, as well as private property owners as necessary (i.e. large
industrial and commercial properties).
Falcon will mail properry owner notification letters for all properties which we will access. In addition, Falcon will
make reasonable attempts to make contact with present occupants of the properties prior to accessing the
properties with drilling equipment. However, if contact cannot be made, the mailed letters will serve as legal
notification and work will proceed.
A number of borings will require access to gated drives on private properties. We request the project team and/or
Division personnel assist Falcon with identifying property owners or representatives thereof that can afford access
through these gates for the completion of our work.
Falcon will locate the test borings in the field using a handheld GPS and coordinates obtained from georeferenced
project drawings provided by others. Following completion of the borings, appro�mate test boring elevations may
be determined by performing a simple level loop utilizing benchmarks or baseline hubs as a reference point if they
can are clearly marked and able to be located by our field professional within a reasonable distance of each
structure. If survey reference points cannot be located, a simple level loop will be performed based on an assumed
elevation and a temporary benchmark will be established by Falcon with an unknown elevation. If the actual
elevation can be determined by others and shared with Falcon, the actual boring elevations will be included in
project deliverables. Otherwise, Falcon will utilize project topographic data to appro�mate test boring elevations.
We anticipate truck, ATV, or rubber track mounted drill rigs equipped with hollow stem augers and an automatic
hammer will be able to access the majoriry of boring locations. However, many portions of the site are wooded
and will require extensive clearing for access. Selecrive clearing will be performed with a rotating drum hydraulic
mulcher ("hydroaxe") and/or by hand with chain saws. Clearing will generally be performed along the path of
easiest access, attempting to roughly follow proposed alignments, and will be limited to the minimum extent
necessary to afford safe passage and working areas for our drill crews. However, where existing trails come within
close proximiry to the proposed boring locations, clearing may be performed from the pathway to the boring
approximately perpendicular to the alignment.
Borings in wetland areas are anticipated to be accessed using a non-amphibious (i.e. not floating) track mounted rig
that can operate in appro�mately 2-3 feet of water. If an amphibious "marsh buggy" rype rig is required for any
borings, additional fees will be required. Upon obtaining actual bridge envelopes and performing field stake-outs,
we will notify you if any borings are likely to require a marsh buggy rig.
A number of borings for the structures noted above as "e�sting alignment" will be performed within or in close
proximiry to existing roadways, requiring the use of lane closures, shoulder closures, or other traffic control
devices. Traffic control services will be performed by certified in-house staff or one of our approved sub-
consultants in general accordance with the Manual on Uniform Traffic Control Devices (NIUTCD) and NCDOT
requirements, utilizing flagmen where appropriate. We assume that any working time restrictions on lane closures
or shoulder closures will not significandy prohibit our progression of work (i.e. allowable working window from
9AM-4PM or similar). No overnight or weekend work is anticipated.
Soil borings will be performed in accordance with the test methods referenced in the NCDOT GEU Geotechnical
Investigation and Recommendations Manual. Soil samples will be collected using a split-barrel sampler during
drilling, visually classified in the field in general accordance with the AASHTO Soil Classification System, sealed in
moisture-proof containers, and transported to our laboratory. Relatively undisturbed, thin-walled "Shelby" tube
samples will be collected in areas of compressible fine-grained soils at bridge approaches to determine soil

parameters for embankment stabiliry and settlement analyses. Rock core samples will be collected where bridge
foundations are anticipated to penetrate into rock and/or to investigate for the present of voids immediately
beneath abrupt and/or shallow refusal in limestone.
Laboratory Testing
Select split spoon and thin-walled "Shelby" tube soil samples, and possibly rock core samples will be transferred to
our laboratory and tested for Atterberg limits, grain size analysis, moisture content, organic content, CU tria�al,
consolidation, and rock core unconfined compressive strength testing . Laboratory testing will be performed in
general accordance with the applicable test method noted in the attached manday estimate.
Geotechnical Re�orting and Recommendations
After completion of Field and Laboratory Investigation by Falcon (Bridges) and Catlin (Culverts), Falcon will
prepare the following documents in general accordance with NCDOT GEU formats:
➢ Structure Subsurface Investigation (11x17, separate for each structure, duals will be combined)
➢ Structure Foundarion Recommendarions (8.5x11 written recommendations, separate for each structure)
It should be noted that the culvert reports and recommendations will be prepared utilizing field data prepared by
Catlin and provided to Falcon as noted in the project description above. We understand a total of six (6) reinforced
concrete box culverts (RCBC) will be included in the project, five (5) on R-3300A and one (1) on R-3300B.
Specific details for each culvert are not provided herein since the reporting effort associated with each culvert is
not anticipated to be significantly influenced by specific size/location.
EXCLUSIONS
Items excluded from this proposal include, but are not limited to the following:
➢ Services associated with roadway design and construction.
➢ Services associated with retaining walls, sound barrier walls, signs, or any other structural elements not
explicitly referenced herein.
➢ Field or laboratory testing for culvert borings.
➢ Field or laboratory test methods not explicitly referenced herein.
➢ Additional borings, deeper borings, or borings at locations significandy different than those referenced
herein as indicated in preliminary plans provided to Falcon by Stantec.
➢ Exceedingly difficult site access considerations such as temporary fills, special access rigs such as crane
mobilized skid rigs or amphibious "swamp bugg�' rigs.
➢ Pavement Investigation or Pavement Design Services.
➢ GeoEnvironmental Services associated with any known or unknown contamination sites. If we believe we
have encountered contamination, we will contact you to discuss appropriate action. Furthermore we
request any known contaminated areas be communicated to us in advance of our mobilization so that we
can be prepared to encounter or avoid contaminated areas.
