Subject: Combat Engineers BN Armory
Tom,
Here are my comments on the SW application package for the C E BN
Armory. If you can clarify anything before I write an official letter
and return the applications to you for revisions, please respond as soon
as possible. I will be reviewing the loth Armory Monday.
1. If site constraints prevent you from providing a 3:1 (L:W) pond
ratio, please provide a weir that will allow tfie runoff to have a longer
settling time before it leaves the pond. Provide a detail with
dimensions.
2. Please specify the permenant vegetation to be planted on the 3:1
sideslopes of the pond on the plans.
3. In your calculations, you state that the pond depth is 4 feet. It
is actually 4.99 feet. If your calcs are based on a 4' depth, you need
to change them or change the pond design.
4. The forebay is sized at 31% of the total volume. We require 20%.
Is there a reason you cannot meet this?
5. You provide a detail of the drive(A C-8). Please reference this
detail on the grading plan, sheet C-6. Please provide proposed
elevations on the drive extension. I cannot tell where the runoff from
this portion of the road will drain to.
6. Cl #4 on sheet C-6 does not show an invert elevation. Please
provide one.
7. On the outlet (effluent) structure detail, please show a screen on
the orifice. Is there a grate at the top of the structure? for
overflow? Please show on detail. Spaces must be a maximum of 4".
8. On the wet pond supplement, you list the impervious area at 31.8
acres. You meant to put .83 acres, right?
9. On page three of the wet pond supplement, #4, you list the
elevations when the sediment shall be removed, please provide the actual
depths, not elevations.
10. Please initial page 4 of 4 on the Stormwater Mangement
Application.

Response to CE BN Comments
✓1. Site restraints prevent lengthening of pond. Pond is currently approximately 33
percent over designed in both surface area and temporary pool volume. Current
length/width aspect ratio of temporary pool is 2.42: 1 (40.54m: 16.7m). If pond
were re-designed to meet specific surface area and volume requirements, the pond
width could be reduced in width to 14.7 meters, providing an acceptable aspect
ratio of 2.76:1. As the revised pond would fit within the footprint of the exiting
design, we request the existing design be accepted as is.
✓2. Permanent vegetation is specified in Section 02823, para. 2.3 of the
specifications. Copies of these specifications were provided with our original
submittal.
f/3. Pond depth is 4 feet (1.2 meters). Permanent Pool Elevation(PPE) on page 3 of 4
of Wet Detention Basin Supplement indicates PPE as 20.34 when it should have
indicated 19.29. See revised page.
V 4. Forebay size modified to 21 percent of total volume, see revised calculations and
drawings C6 and C10.
V5. See revised drawing C6 and C8. Centerline elevations of drive shown on A/C8,
"Profile of CE BN Drive"; additional elevations shown on revised C6. Profile
elevations referenced by Keyed Note 15; 3/C8 and 4/C8 referenced by section
cuts on C6.

operations and diligently pursue the control of erosion and siltation, the
Contracting Officer may suspend the Contractor's operations until such time
as the work is coordinated in a manner acceptable to the Contracting
' Officer.
3.2 SEEDBED PREPARATION
' The Contractor shall cut and satisfactorily dispose of weeds or other
unacceptable growth on the areas to be seeded. The soil shall then be
scarified or otherwise loosened to a depth of not less than 75 mm (3
inches) except as otherwise provided below or otherwise directed by the
' Contracting Officer. Clods shall be broken and the top 50 to 75 mm (2 to 3
inches) of soil shall be worked into an acceptable seedbed by the use of
soil pulverizers, drags, or harrows; or by other methods approved by the
Contracting Officer. All rock and debris 75 mm (3 inches) or larger shall
' be removed prior to the application of seed and fertilizer. On cut slopes
that are 2 :1 and steeper, both the depth of preparation and the degree of
smoothness of the seedbed may be reduced as permitted by the Contracting
Officer, but in all cases the slope surface shall be scarified, grooved,
' trenched, or punctured so as to provide pockets, ridges, or trenches in
which the seeding materials can lodge. On cut slopes that are either 2 :1
or steeper, the Contracting Officer may permit the preparation of a partial
or complete seedbed during the initial grading of the slope. If at the
' time of final seeding and mulching operations such initial preparation is
still in a condition acceptable to the Contracting Officer, additional
seedbed preparation may be reduced or eliminated. Seedbed preparation
within 2 feet of the edge of any pavement shall be limited to a depth of 50
' to 75 mm 12 to 3 inches) . The preparation of seedbeds shall not be done
when the soil is frozen, extremely wet, or when the Contracting Officer
determines that it is an otherwise unfavorable working condition.

directed by the Contracting Officer. Such pruning shall be in accordance
with the plans, generally accepted horticultural practices, and according
to shape, size, and condition of the individual plant.
- After the plant hole is dug, the walls and floor of the plant hole shall be
scarified. The plant shall then be placed in the prepared plant hole at
the proper position as regards to depth, alignment, final grade of the
surrounding ground level, and vertical placement of the trunk. This
position shall be maintained during all subsequent backfilling and watering
operations. The depth. to which plants are to be set shall be the same as
in the nursery or collection site unless otherwise directed.
After one-half to two-thirds of the backfilling and tamping has been
completed, and if the soil in the plant holes is not sufficiently moist it
shall be moistened with water. The quantity of water applied shall be such
' as to moisten all soil particles but shall not be an amount that will
saturate the .soil to the extent of excluding all air from around the roots.
After absorption of the water is sufficiently complete, the remainder of
the backfill shall be placed.

' ASTM C 94 and ACI 301. Machine mix concrete. Begin mixing within 30
minutes after the cement has been added to the aggregates. Place concrete
within 90 minutes of either addition of mixing water to cement and
aggregates or addition of cement to aggregates if the air temperature is
' less than 29 degrees C. Reduce mixing time and place concrete within 60
minutes if the air temperature is greater than 29 degrees C except as
follows: if set retarding admixture is used and slump requirements can be
met, limit for placing concrete may remain at 90 minutes. Additional water
' may be added, provided that both the specified maximum slump and
water-cement ratio are not exceeded. when additional water is added, an
additional 30 revolutions of the mixer at mixing speed is required. If the
entrained air content falls below the specified limit, add a sufficient
' quantity of admixture to bring the entrained air content within the
SECTION 03300 Page 9
' ARMORIES, MCB, CAMP LEJEUNE, NC 05999158
specified limits. Dissolve admixtures in the mixing water and mix in the
drum to uniformly distribute the admixture throughout the batch.
' 3 .5.3 Transporting
Transport concrete from the mixer to the forms as rapidly as practicable.
Prevent segregation or loss of ingredients. Clean transporting equipment
thoroughly before each batch. Do not use aluminum pipe or chutes . Remove
concrete which has segregated in transporting and dispose of as directed.
3 .6 PLACING CONCRETE
' Place concrete as soon as practicable after the forms and the reinforcement
have been inspected and approved. Do not place concrete when weather
conditions prevent proper placement and consolidation; in uncovered areas
' during periods of precipitation; or in standing water. Prior to placing
concrete, remove dirt, construction debris, water, snow, and ice from
within the forms. Deposit concrete as close as practicable to the final
position in the forms. Do not exceed a free vertical drop of 1 m from the
' point of discharge. Place concrete in one continuous operation from one
end of the structure towards the other. Position grade stakes on 3 m
centers maximum in each direction when pouring interior slabs and on 6 m
centers maximum for exterior slabs.
3.6. 1 Footing Placement
Concrete for footings may be placed in excavations without forms upon
' inspection and approval by the Contracting officer. Excavation width shall
be a minimum of 100 mm greater than indicated.
3.6.2 Vibration
ACI 301. Furnish a spare vibrator on the job site whenever concrete is
placed. Consolidate concrete slabs greater than 100 mm in depth with high
frequency, internal, mechanical vibrating equipment supplemented by hand
spading and tamping. Consolidate concrete slabs 100 mm or less in depth by
' wood tampers, spading, and settling with a heavy leveling straightedge.
Operate vibrators with vibratory element submerged in the concrete, with a
minimum frequency of not less than 6000 impulses per minute when submerged.
Do not use vibrators to transport the concrete in the forms. Insert and
' withdraw vibrators approximately 500 mm apart. Penetrate the previously
placed lift with the vibrator when more than one lift is required. Place
concrete in 500 mm maximum vertical lifts. External vibrators shall be
used on the exterior surface of the forms when internal vibrators do not
' provide adequate consolidation of the concrete.
3.6.3 Pumping
' ACI 304R and ACI 304.2R. Pumping shall not result in separation or loss of
materials nor cause interruptions sufficient to permit loss of plasticity
between successive increments. Loss of slump in pumping equipment shall
not exceed 50 mm. Concrete shall not be conveyed through pipe made of
aluminum or aluminum alloy. Rapid changes in pipe sizes shall be avoided.
Maximum size of course aggregate shall be limited to 33 percent of the
diameter of the pipe. Maximum size of well rounded aggregate shall be
limited to 40 percent of the pipe diameter. Samples for testing shall be
' taken at both the point of delivery to the pump and at the discharge end.
3.6.4 Cold Weather
ACI 306.1. Do not allow concrete temperature to decrease below 10 degrees C
Obtain approval prior to placing concrete when the ambient temperature is
below 4 degrees C or when concrete is likely to be subjected to freezing
temperatures within 24 hours. Cover concrete and provide sufficient heat
' to maintain 10 degrees C minimum adjacent to both the formwork and the
SECTION 03300 Page 10
' ARMORIES, MCB, CAMP LEJEUNE, NC 05999158
' structure while curing. Limit the rate of cooling to 3 degrees C in any 1
hour and 10 degrees C per 24 hours after heat application.
' 3 .6 .5 Hot Weather
ACI 305R. Maintain required concrete temperature using Figure 2 .1. 5 in ACI
305R to prevent the evaporation rate from exceeding 1 kg per square meter
of exposed concrete per hour. Cool ingredients before mixing or use other
suitable means to control concrete temperature and prevent rapid drying of
newly placed concrete. Shade the fresh concrete as soon as possible after
placing. Start curing when the surface of the fresh concrete is
' sufficiently hard to permit curing without damage. Provide water hoses,
pipes, spraying equipment, and water hauling equipment, where job site is
remote to water source, to maintain a moist concrete surface throughout the
curing period. Provide burlap cover or other suitable, permeable material
' with fog spray or continuous wetting of the concrete when weather
conditions prevent the use of either liquid membrane curing compound or
impervious sheets. For vertical surfaces, protect forms from direct
sunlight and add water to top of structure once concrete is set.

Provide for surfaces not exposed to public view. Patch this holes and
defects and level abrupt irregularities. Remove or rub off fins and other-
projections exceeding 6 mm in height.
3.7.3.3 Smooth Form Finish
Provide smooth form finish in accordance with ACI 301 for areas indicated.
' 3.7.4 Smooth Rubbed Finish
Provide concrete with a smooth rubbed finish as follows:
' a. Interior Exposed to View Walls: Smooth rubbed finish shall be
produced on newly hardened concrete no later than the day
following form removal. Surfaces shall be wetted and rubbed with
carborundum brick or other abrasive until uniform color and

' texture are produced. No cement grout shall be used other than
the cement paste drawn from the concrete itself by the rubbing
process.
3 .8 FLOOR, SLAB, AND PAVEMENT FINISHES AND MISCELLANEOUS CONSTRUCTION
ACI 302 . 1R, unless otherwise specified. Slope floors uniformly to drains
' where drains are provided. Depress the concrete base slab where quarry
tile or ceramic tile are indicated. Steel trowel and fine-broom finish
concrete slabs that are to receive quarry tile, ceramic tile, or paver
tile. Where straightedge measurements are specified, Contractor shall
' provide straightedge.
3 .8.1 Finish
' Place, consolidate, and immediately strike off concrete to obtain proper
contour, grade, and elevation before bleedwater appears. Permit concrete
to attain a set sufficient for floating and supporting the weight of the
finisher and equipment. If bleedwater is present prior to floating the
' surface, drag the excess water off or remove by absorption with porous
materials. Do not use dry cement to absorb bleedwater.
3 . 8.1.1 Floated
' Use for surfaces to receive roofing, waterproofing membranes, and exterior
slabs where not otherwise specified. After the concrete has been placed,
consolidated, struck off, and leveled, do not work the concrete further,
until ready for floating. Whether floating with a wood, magnesium, or
composite hand float, with a bladed power trowel equipped with float shoes,
or with a powered disc, float shall begin when the surface has stiffened
sufficiently to permit the operation. During or after the first floating,
surface shall be checked with a 3 meter straightedge applied at no less
than two different angles, one of which is perpendicular to the direction
of strike off. High spots shall be cut down and low spots filled during
this procedure to produce a surface level within 6 mm in 3 m.
' 3 .8.1.2 Steel Troweled
Use for floors intended as walking surfaces and for reception of floor
coverings. First, provide a floated finish. The finish shall next be
' power troweled two times, and finally hand troweled. The first troweling
after floating shall produce a smooth surface which is relatively free of
defects but which may still show some trowel marks. Additional trowelings
shall be done by hand after the surface has hardened sufficiently. The
' final troweling shall be done when a ringing sound is produced as the
trowel is moved over the surface. The surface shall be thoroughly
consolidated by the hand troweling operations. The finished surface shall
be essentially free of trowel marks and uniform in texture and appearance.
' The finished surface shall produce a surface level to within 6 mm in 3 m.
On surfaces intended to support floor coverings, any defects of sufficient
magnitude to show through the floor covering shall be removed by grinding.
3 .8.1.3 Nonslip Finish
' Use on surfaces of exterior platforms, steps, and landings; and on exterior
and interior pedestrian ramps. Apply dry shake aggregate of ceramically
' bonded aluminum oxide to the surface at a minimum rate of 1.2 kg per square
M. Blend approximately two-thirds of the aggregate with Portland cement as
recommended by the manufacturer and apply to the surface evenly and without
segregation. After blended material has been embedded by floating, apply
' the remainder of the blended material to the surface at right angles to the
previous application. Apply blended material heavier in any areas not
sufficiently covered by the first application. Perform a second floating
immediately following the first. After the selected material has been
embedded by the two floatings, complete the operation with a troweled
SECTION 03300 Page 12

finish.
3.8 .1.4 Broomed
' Use on surfaces of exterior walks, platforms, patios, and ramps, unless
otherwise indicated. Perform a floated finish, then draw a broom or burlap
belt across the surface to produce a coarse scored texture. Permit surface
' to harden sufficiently to retain the scoring or ridges. Broom transverse
to traffic or at right angles to the slope of the slab.
3.8.1.5 Pavement
Screed the concrete with a template advanced with a combined longitudinal
and crosswise motion. Maintain a slight surplus of concrete ahead of the
template. After screeding, float the concrete longitudinally. Use a
' straightedge to check slope and flatness; correct and refloat as necessary.
Obtain final finish by a burlap drag. Drag a strip of clean, wet burlap
from 900 to 3000 mm wide and 600 mm longer than the pavement width across
the slab. Produce a fine, granular, sandy textured surface without
' disfiguring marks. Round edges and joints with an edger having a radius of
3 mm.
3.8.2 Concrete walks
' Provide 100 mm thick minimum. Provide contraction joints spaced every 1500
lineal mm unless otherwise indicated. Cut contraction joints 25 mm deep
with a jointing tool after the surface has been finished. Provide 13 mm
thick transverse expansion joints at changes in direction where sidewalk
' abuts curb, steps, rigid pavement, or other similar structures; space
expansion joints every 15 m maximum. Give walks a broomed finish. Unless
indicated otherwise, provide a transverse slope of 1/48. Limit variation
in cross section to 6 mm in 1500 mm.
' 3.8.3 Pits and Trenches
Place bottoms and walls monolithically or provide waterstops and keys.
' 3.8.4 Curbs and Gutters
Provide contraction joints spaced every 3 m maximum unless otherwise
indicated. Cut contraction joints 20 mm deep with a jointing tool after
the surface has been finished. Provide expansion joints 13 mm thick and
spaced every 30 mm maximum unless otherwise indicated. Perform pavement
finish.
' 3.9 CURING AND PROTECTION
ACI 301 unless otherwise specified. Begin curing immediately following
form removal. Avoid damage to concrete from vibration created by blasting,
pile driving, movement of equipment in the vicinity, disturbance of
formwork or protruding reinforcement, and any other activity resulting in
ground vibrations. Protect concrete from injurious action by sun, rain,
flowing water, frost, mechanical injury, tire marks, and oil stains. Do
not allow concrete to dry out from time of placement until the expiration
of the specified curing period. Do not use membrane-forming compound on
surfaces where appearance would be objectionable, on any surface to be
' painted, where coverings are to be bonded to the concrete, or on concrete
to which other concrete is to be bonded. If forms are removed prior to the
expiration of the curing period, provide another curing procedure specified
herein for the remaining portion of the curing period. Provide moist
' curing for those areas receiving liquid chemical sealer-hardener or epoxy
coating.
3.9.1 Moist Curing
SECTION 03300 Page 13

' ARMORIES, MCB, CAMP LEJEUNE, NC 05999158
' Remove water without erosion or damage to the structure.
3 . 9.1. 1 Ponding or Immersion
' Continually immerse the concrete throughout the curing period. Water shall
not be more than 10 degrees C less than the temperature of the concrete.
For temperatures between 4 and 10 degrees C, increase the curing period by
50 percent.
3 .9.1.2 Fog Spraying or Sprinkling
Apply water uniformly and continuously throughout the curing period. For
temperatures between 4 and 10 degrees C, increase the curing period by 50
percent.
' 3 .9.1.3 Pervious Sheeting
Completely cover surface and edges of the concrete with two thicknesses of
wet sheeting. Overlap sheeting 150 mm over adjacent sheeting. Sheeting
shall be at least as long as the width of the surface to be cured. During
application, do not drag the sheeting over the finished concrete nor over
sheeting already placed. Wet sheeting thoroughly and keep continuously wet
throughout the curing period.
' 3 .9.1.4 Impervious Sheeting
Wet the entire exposed surface of the concrete thoroughly with a fine spray
of water and cover with impervious sheeting throughout the curing period.
' Lay sheeting directly on the concrete surface and overlap edges 300 mm
minimum. Provide sheeting not less than 450 mm wider than the concrete
surface to be cured. Secure edges and transverse laps to form closed
joints. Repair torn or damaged sheeting or provide new sheeting. Cover or
' wrap columns, walls, and other vertical structural elements from the top
down with impervious sheeting; overlap and continuously tape sheeting
joints; and introduce sufficient water to soak the entire surface prior to
completely enclosing.
' 3.9.2 Liquid Membrane-Forming Curing Compound
Seal or cover joint openings prior to application of curing compound.
' Prevent curing compound from entering the joint. Apply in accordance with
the recommendations of the manufacturer immediately after any water sheen
which may develop after finishing has disappeared from the concrete
surface. Provide and maintain compound on the concrete surface throughout
the curing period. Do not use this method of curing where the use of
Figure 2.1.5 in ACI 305R indicates that hot weather conditions will cause
an evaporation rate exceeding one kg pf water per square meter per hour.
3.9.2.1 Application
Unless the manufacturer recommends otherwise, apply compound immediately
after the surface loses its water sheen and has a dull appearance, and
' before joints are sawed. Mechanically agitate curing compound thoroughly
during use. Use approved power-spraying equipment to uniformly apply two
coats of compound in a continuous operation. The total coverage for the
two coats shall be 5 square meters maximum per L of undiluted compound
unless otherwise recommended by the manufacturer's written instructions.
The compound shall form a uniform, continuous, coherent film that will not
check, crack, or peel. Immediately apply an additional coat of compound to
areas where the film is defective. Re-spray concrete surfaces subjected to
' rainfall within 3 hours after the curing compound application.
3 .9.2.2 Protection of Treated Surfaces
' Prohibit pedestrian and vehicular traffic and other sources of abrasion at
SECTION 03300 Page 14

' least 72 hours after compound application. Maintain continuity of the
coating for the entire curing period and immediately repair any damage.
' 3 . 9.3 Liquid Chemical Sealer-Hardener
Apply sealer-hardener to interior floors not receiving floor covering and
floors located under access flooring. Apply the sealer-hardener in
' accordance with manufacturer's recommendations. Seal or cover joints and
openings in which joint sealant is to be applied as required by the joint
sealant manufacturer. The sealer-hardener shall not be applied until the
concrete has been moist cured and has aged for a minimum of 30 days. Apply
a minimum of two coats of sealer-hardener.
' 3. 9.4 Curing Periods
ACI 301 except 10 days for retaining walls, pavement or chimneys, 21 days
' for concrete that will be in full-time or intermittent contact with
seawater, salt spray, alkali soil or waters. Begin curing immediately
after placement. Protect concrete from premature drying, excessively hot
temperatures, and mechanical injury; and maintain minimal moisture loss at
' a relatively constant temperature for the period necessary for hydration of
the cement and hardening of the concrete. The materials and methods of
curing shall be subject to approval by the Contracting Officer.
3 . 9.5 Requirements for Type III, High-Early-Strength Portland Cement
The curing periods shall be not less than one-fourth of those specified for
Portland cement, but in no case less than 72 hours.
' 3 . 10 FIELD QUALITY CONTROL
3 . 10.1 Sampling
' ASTM C 172. Collect samples of fresh concrete to perform tests specified.
ASTM C 31/C 31M for making test specimens.
' 3 . 10.2 Testing
3 . 10.2.1 Slump Tests
' ASTM C 143 . Take concrete samples during concrete placement. The maximum
slump may be increased as specified with the addition of an approved
admixture provided that the water-cement ratio is not exceeded. Perform
tests at commencement of concrete placement, when test cylinders are made,
t and for each batch (minimum) or every 16 cubic meters (maximum) of concrete.
3.10.2.2 Temperature Tests
' Test the concrete delivered and the concrete in the forms. Perform tests
in hot or cold weather conditions (below 10 degrees C and above 27 degrees C
) for each batch (minimum) or every 16 cubic meters (maximum) of concrete,
until the specified temperature is obtained, and whenever test cylinders
and slump tests are made.
3 .10.2.3 Compressive Strength Tests
ASTM C 39. Make five test cylinders for each set of tests in accordance
with ASTM C 31/C 31M. Precautions shall be taken to prevent evaporation
and loss of water from the specimen. Test two cylinders at 7 days, two
cylinders at 28 days, and hold one cylinder in reserve. Samples for
' strength tests of each mix design of concrete placed each day shall be
taken not less than once a day, nor less than once for each 120 cubic meters
of concrete, nor less than once for each 500 square meters of surface area
for slabs or walls. For the entire project, take no less than five sets of
' samples and perform strength tests for each mix design of concrete placed.

ARMORIES, MCB, CAMP LEJEUNE, NC 05999158
Each strength test result shall be the average of two cylinders from the
same concrete sample tested at 28 days. If the average of any three
consecutive strength test results is less than f'c or if any strength test
result falls below f'c by more than 3 MPa, take a minimum of three _-_STM C 42
core samples from the in-place work represented by the low test cv inder
results and test. Concrete represented by core test shall be considered
structurally adequate if the average of three cores is equal to at least 85
percent of f'c and if no single core is less than 75 percent of f ' c.
' Locations represented by erratic core strengths shall be retested. Remove
concrete not meeting strength criteria and provide new acceptable concrete.
Repair core holes with nonshrink grout. Match color and finish of
adjacent concrete.
1 3.10.2.4 Air Content
