General
Construction
- It is the contractor's responsibility to
develop and maintain an erection procedure to insure the stability of the
building and safety for personnel during construction.
- Contractor shall follow all applicable safety
standards and building codes, during construction.
- Refer to the pre-engineered building design
drawings for the structural design of the building and the anchor bolt
layout.
- Locate fire extinguishers in the office area
and in the manufacturing area, as required by codes.
- The new building shall be grounded in
accordance with NFPA, as shown on the electrical drawings.

Foundations
- The foundation design is based upon an
allowable soil bearing f 2000 p.s.f. which shall be verified by an
independent testing laboratory.
- If soft or wet soil is found at the
bearing elevation, it shall be removed for a depth of 24 in. and replaced
with compacted granular fill.
- The contractor shall take necessary
precautions to insure that the foundation excavations remain dry during
construction.
- Compact all bearing surfaces with a
tamper prior to placing rebar.
- Compact interior fill in 6" lifts
around piers and behind walls. Assure that all walls and piers have
attained sufficient strength prior to placing backfill (allow min. 7 days
curing).
- The bottom of all footing shall be a
minimum of 3' - 0" below top of final grade.
back to top
Masonry
- All masonry work shall be in conformance
with the latest edition of "Building Code Requirements for Masonry
Structures" and "The Specifications for Masonry Structures"
of The American Concrete Institute (ACI 530).
- Concrete masonry units (block) shall
conform to ASTM C90, and have a minimum compressive strength F'm = 1500
psi.
- Mortar shall conform to ASTM C270, type
M or S.
- Grout fill shall attain a minimum
strength F'c = 3000 psi
- Maximum aggregate size shall be
3/8"

Insulation
- The exterior walls shall be insulated
with R-13 rated insulation.
- The roof shall be insulated with R-19
rated insulation.
- All insulation shall be compliance with
NAIMA Standard 202, ASTM E84-80 (flame spread of 25 and smoke developed of
50).
- Place 2" board insulation around
the interior perimeter of all frost walls, extended from the top of the
footing to the underside of the floor slab. Assure that all joints
are tight.

Accessibility
Notes
- All exit doors shall be in accordance
with the requirements of The Americans with Disabilities Act.
Hardware shall allow the doors to be easily openable from the side which
egress is to be made, without the use of a key or other special knowledge
or effort.
- All door closers shall operate with a
maximum force of 5lb.
- All restroom fixtures shall be
manufactured and installed in conformance with The Americans with
Disabilities Act.
- Set rim of water closet at 18"
above finished floor.
- Set top of lavatory at 34" AFF.
- Provide grab bars behind and along one side of the water
closet.

conformance with the latest edition of "Structural Concrete for
Buildings" (ACI-301), and "Building Code Requirements for
Reinforced Concrete" (ACI-318).
- Comply with acceptable hot and cold
weather concrete standards.
- Cure all concrete in accordance with recommended practices of
ACI-301.
- Provide concrete with the following 28
day strengths:
- Footings & Piers.........3000
p.s.i. with 5% ± 1% entrained air
- Slab (interior).............3000
p.s.i.
- Slab (exterior)............4000
p.s.i. with 5% ± 1% entrained
air
- All reinforcing steel is to be

welded wire fabric, use 6 x 6 W 1.4 x W 1.4
- Place wire mesh in the center of the
slab, and take measures to maintain its location.
- Lap wire mesh 12"
- Welded wire fabric shall conform with ASTM A185.
- Provide 0.006 polyethylene vapor
retarder under new interior slabs, overlap edges 6" min.
- Provide 6" of compacted stone fill
below all slabs.
- Lap all reinforcing bars a minimum of 24
in., unless otherwise noted on the design drawings.
- Maintain a minimum concrete cover of
2" for all concrete exposed to weather or earth fill and maintain
3" for all concrete cast against earth.
- Place ½ in. expansion joint material
between all piers and the interior slab, and at any location where new
concrete is poured against existing concrete.
- Anchor bolts are to be A307 material.
The threads of all bolts shall be greased before placing concrete.
- Refer to the pre-engineered building
drawings for anchor bolt locations.
