Apply according to manufacturer's written instructions after placing, screeding, and bull floating or darbying concrete, but before float finishing.

C. Formed Surfaces: Cure formed concrete surfaces, including underside of beams, supported slabs, and other similar surfaces. If forms remain during curing period, moist cure after loosening forms. If removing forms before end of curing period, continue curing for the remainder of the curing period.

D. Unformed Surfaces: Begin curing immediately after finishing concrete. Cure unformed surfaces, including floors and slabs, concrete floor toppings, and other surfaces.

E. Cure concrete according to ACI 308.1, by one or a combination of the following methods:

1. Moisture Curing: Keep surfaces continuously moist for not less than seven days with the following materials:

a. Water.

b. Continuous water-fog spray.

c. Absorptive cover, water saturated, and kept continuously wet. Cover concrete surfaces and edges with 12-inch lap over adjacent absorptive covers. See

2. Curing Compound: Apply uniformly in continuous operation by power spray or roller according to manufacturer's written instructions immediately after finishing.

3.10 CONCRETE SURFACE REPAIRS

A. Defective Concrete: Repair and patch defective areas when approved by COR. Remove and replace concrete that cannot be repaired and patched to COR's approval.

B. Patching Mortar: Mix dry-pack patching mortar, consisting of one part portland cement to two and one-half parts fine aggregate passing a No. 16 sieve, using only enough water for handling and placing.

C. Repairing Formed Surfaces: Surface defects include color and texture irregularities, cracks, spalls, air bubbles, honeycombs, rock pockets, fins and other projections on the surface, and stains and other discolorations that cannot be removed by cleaning.

1. Immediately after form removal, cut out honeycombs, rock pockets, and voids more than 1/2 inch in any dimension in solid concrete, but not less than 1 inch in depth. Make edges of cuts perpendicular to concrete surface. Clean, dampen with water, and brush-coat holes and voids with bonding agent. Fill and compact with patching mortar before

CAST-IN-PLACE CONCRETE 03 30 00 - 11

bonding agent has dried. Fill form-tie voids with patching mortar or cone plugs secured in place with bonding agent.

2. Repair defects on surfaces exposed to view by blending white portland cement and standard portland cement so that, when dry, patching mortar will match surrounding color. Patch a test area at inconspicuous locations to verify mixture and color match before proceeding with patching. Compact mortar in place and strike off slightly higher than surrounding surface.

3. Repair defects on concealed formed surfaces that affect concrete's durability and structural performance as determined by COR.

D. Perform structural repairs of concrete, subject to COR's approval, using epoxy adhesive and patching mortar.

E. Repair materials and installation not specified above may be used, subject to COR's approval.

PART 3 - EXECUTION

3.2 EXCAVATION FOR ELECTRICAL WORK

A. All excavations shall comply with OSHA requirements. Shore and brace as required for stability of excavation.

B. De-Watering:

1. Prevent surface water and subsurface or groundwater from flowing into excavations and from flooding project site and surrounding area. Do not allow water to accumulate in excavations. Remove water to prevent softening of bearing materials. Provide and maintain de-watering system components necessary to convey water away from excavations. Establish and maintain temporary drainage ditches and other diversions outside excavation limits to convey surface water to collecting or run-off areas. Do not use trench excavations as temporary drainage ditches.

C. Material Storage:

1. Stockpile satisfactory excavated materials where directed, until required for backfill or fill. Place, grade and shape stockpiles for proper drainage. Locate and retain soil materials away from edge of excavations. Do not store within drip-line of trees indicated to remain. Remove and legally dispose of excess excavated materials and materials not acceptable for use as backfill or fill.

D. Excavation for Underground Electrical Structures:

1. Conform to elevations and dimensions shown within a tolerance of plus or minus 0.10-foot;

plus a sufficient distance to permit placing and removal of concrete formwork, installation of services, other construction and for inspection. This includes trenching, installation and splicing or other joining of cables and testing of cables. Excavate, by hand, areas within drip-line of large trees. Protect the root system from damage and dry-out. Maintain moist conditions for root system and cover exposed roots with burlap. Paint root cuts of 1-inch in diameter and larger with emulsified asphalt tree paint. Take care not to disturb bottom of excavation.

Excavate by hand to final grade just before concrete reinforcement is placed.

E. Trenching:

1. Excavate trenches for electrical installations as follows:

a. Excavate trenches to the uniform width, sufficiently wide to provide ample working room and clearance on both sides of raceways and equipment.

b. Excavate trenches to depth indicated or required.

JANUARY 2024

ELECTRICAL 26 05 00- 6

c. Limit the length of open trench to that in which installations can be made and the trench backfilled within the same day.

F. Cold Weather Protection:

1. Protection excavation bottoms against freezing when atmospheric temperature is less than 35 degrees F:

G. Backfilling and Filling:

1. Place soil materials in layers to subgrade elevations for each area classification listed below, using materials specified in PART 2 of this Section. Backfill excavations as promptly as work permits, but not until completion of inspection, testing, approval, and locations of underground utilities have been recorded; concrete formwork has been removed; voids have been backfilled;

and trash and debris has been removed.

a. Under building slabs, use drainage fill materials.

b. Under piping and equipment, use sub-base materials where required over rock bearing surface and for correction of unauthorized excavation.

c. Other areas, use excavated or borrowed materials.

H. Placement and Compaction:

1. Place backfill and fill materials in layers of not more than 8 inches in loose depth for material compacted by heavy equipment and not more than 4 inches in loose depth for material compacted by hand-operated tampers.

I. Before Compaction:

1. Moisten or aerate each layer as necessary to provide optimum moisture content. Compact each layer to required percentage of maximum dry density or relative dry density for each area classification specified. Do not place backfill or material on surfaces that are muddy, frozen, or contain frost or ice.

J. Backfill Placement:

1. Place backfill and fill materials evenly adjacent to structures, piping and equipment to required elevations.
