Version: January 2012
the following percentages of relative density, determined in accordance with ASTM D 2049,
for soils which will not exhibit a well-defined moisture-density relationship (cohesionless
soils).
1. Areas Under Structures, Building Slabs and Steps, Pavements: Compact top 12
inches of subgrade and each layer of backfill or fill material to 90 percent maximum
density for cohesive material, or 95 percent relative density for cohesionless
material.
2. Areas Under Walkways: Compact top 6 inches of subgrade and each layer of backfill
or fill material to 90 percent maximum density for cohesive material, or 95 percent
relative density for cohesionless material.
3. Other Areas: Compact top 6 inches of subgrade and each layer of backfill or fill
material to 85 percent maximum density for cohesive soils, and 90 percent relative
density for cohesionless soils.
P. Moisture Control: Where subgrade or layer of soil material must be moisture conditioned
before compaction, uniformly apply water. Apply water in minimum quantity necessary to
achieve required moisture content and to prevent water appearing on surface during, or
subsequent to, compaction operations.
Q. Repair all paving, etc., damaged in the execution of electrical work to the satisfaction of all
parties concerned.
R. Subsidence: Where subsidence occurs at electrical installation excavations during the period
12 months after Substantial Completion, remove surface treatment (i.e., pavement, lawn, or
other finish), add backfill material, compact to specified conditions, and replace surface
treatment. Restore appearance, quality, and condition of surface or finish to match adjacent
areas.
S. Additional Excavation: Where excavation has reached required subgrade elevations, if
unsuitable bearing materials are encountered, continue excavation until suitable bearing
materials are reached.
T. Unauthorized excavation consists of removal of materials beyond indicated subgrade
elevations or dimensions without specific direction from the Architect.
3.04 ERECTION OF METAL SUPPORTS AND ANCHORAGE
A. Cut, fit, and place miscellaneous metal fabrications accurately in location, alignment, and
elevation to support and anchor electrical materials and equipment.
B. Field Welding: Comply with AWS "Structural Welding Code."
3.05 ERECTION OF WOOD SUPPORTS AND ANCHORAGE
A. Cut, fit, and place wood grounds, nailers, blocking, and anchorage accurately in location,
alignment, and elevation to support and anchor electrical materials and equipment.
B. Select fastener sizes that will not penetrate members where opposite side will be exposed to
view or will receive finish materials. Make tight connections between members. Install
fasteners without splitting wood members.
C. Attach to substrates as required to support applied loads.
3.06 APPLICATION OF JOINT SEALERS
A. General: Comply with joint sealer manufacturers' printed application instructions applicable to
products and applications indicated, except where more stringent requirements apply.
1. Comply with recommendations of ASTM C 962 for use of elastomeric joint sealants.
2. Comply with recommendations of ASTM C 790 for use of acrylic- emulsion joint
sealants.
