EXECUTION
FORMWORK
Installation: Conform to ACI 347. Construct forms to obtain concrete of the shapes, dimensions and profiles indicated, with tight joints.
Design and construct forms to prevent bowingout of forms between supports and to be removable without prying against or otherwise damaging fresh concrete.
When patching formed concrete, seal form edges against existing surface to prevent leakage; set forms so that patch is flush with adjacent surfaces.
Treating and Wetting: Treat or wet concrete contact surfaces:
Coat plywood and lumber forms with nonstaining form sealer.
Wet wood forms thoroughly when they are not treated with form release agent.
Prevent water from accumulating and remaining within forms.
Clean and coat removable metal forms with light form oil before reinforcement is placed.
In hot weather, cool metal forms by thoroughly wetting with water just before placing concrete.
Prevent water from accumulating and remaining within forms.
Inserts, Sleeves, and Similar Items: Install flashing reglets, masonry ties, anchors, inserts, wires, hangers, sleeves, boxes for floor hinges, and other castin items specified in other Sections. Place where indicated, square, flush and secured to formwork.
Construction Tolerances - General: Install and maintain concrete formwork to assure completion of work within specified tolerances.
Adjust or replace completed work exceeding specified tolerances before placing concrete.
REINFORCEMENT
Install concrete reinforcement according to ACI 318 and ACI SP66.
Support and securely tie reinforcing steel to prevent displacement during placing of concrete.
Drilling for Dowels in Existing Concrete: Use sharp bits, drill hole slightly oversize, fill with epoxy grout, inset the dowel, and remove excess epoxy.
VAPOR BARRIER
Except where membrane waterproofing is required, place interior concrete slabs on a continuous vapor barrier.
Lap joints 150 mm (6 inches) and seal with a compatible pressuresensitive tape.
Patch punctures and tears.
PLACING CONCRETE
Remove water from excavations before concrete is placed. Remove hardened concrete, debris and other foreign materials from interior of forms, and from inside of mixing and conveying equipment. Obtain approval from COR before placing concrete.
Install screeds at required elevations for concrete slabs.
Roughen and clean free from laitance, foreign matter, and loose particles before placing new concrete on existing concrete.
Blowout areas with compressed air and immediately coat contact areas with adhesive in compliance with manufacturer's instructions.
Place structural concrete according to ACI 301 and ACI 318.
Convey concrete from mixer to final place of deposit by method that will prevent segregation or loss of ingredients. Do not deposit, in Work, concrete that has attained its initial set or has contained its water or cement more than 1 1/2 hours. Do not allow concrete to drop freely more than 1500 mm (5 feet) in unexposed work nor more than 900 mm (3 feet) in exposed work.
Place and consolidate concrete in horizontal layers not exceeding 12 inches in thickness. Consolidate concrete by spading, rodding, and mechanical vibrator. Do not secure vibrator to forms or reinforcement. Continuously vibrate during placement of concrete.
Hot Weather Concrete Placement: As recommended by ACI 305.1 to prevent adversely affecting properties and serviceability of hardened concrete.
Cold Weather Concrete Placement: As recommended by ACI 306.1, to prevent freezing of thin sections less than 12 inches and to permit concrete to gain strength properly.

Protect exposed surfaces of concrete from premature drying, wash by rain or running water, wind, mechanical damage, and excessive hot or cold temperatures.
Curing Methods: Cure concrete with curing compound using wet method with sheets.
Formed Concrete Curing: Wet the tops and exposed portions of formed concrete and keep moist until forms are removed.
If forms are removed before 14 days after concrete is cast, install sheet curing materials as specified above.
Concrete Flatwork Curing:
Install sheet materials according to the manufacturer's instructions.
When manufacturer's instructions deviate from specifications, submit proposed resolution for COR consideration.
FORM REMOVAL
Maintain forms in place until concrete is selfsupporting, with construction operation loads.
Remove fins, laitance and loose material from concrete surfaces when forms are removed. Repair honeycombs, rock pockets, sand runs, spalls, or otherwise damaged surfaces by patching with the same mix as concrete minus the coarse aggregates.
Finish to match adjacent surfaces.
