Buffalo Wild Wings

Buffalo Wild Wings
N. Screed floors level, maintaining surface flatness of maximum 1/4 inch in 10 ft.
3.05 CONCRETE FINISHING
A. (CONC1) Unexposed Form Finish: Repair surface defects, including tie holes, immediately
after removing formwork. Rub down or chip off fins or other raised areas 1/4 inch or more in
height.
C. (CONC2) Interior Concrete Slabs: Finish to requirements of ACI 302.1R, and as follows:
1. Steel trowel surfaces that will receive carpeting, resilient flooring, and thin set ceramic tile.
2. In areas with floor drains, maintain floor elevation at walls; pitch surfaces uniformly to
drains at 1:100 nominal. Provide an 8 inch diameter slope area around all floor drains.
E. (CONC3) Exterior Horizontal Concrete Surfaces: Apply a broom finish to exterior concrete
sidewalks, and ramps, and elsewhere as indicated.
1. Immediately after float finishing, slightly roughen surface by brooming with fiber-bristle
broom perpendicular to main traffic route.
2. Refer to Section 03351 for hardener / sealer applied to exterior concrete surfaces.
F. Interior Curbs: Provide monolithic finish to interior curbs by stripping forms while concrete is
still green and by steel-troweling surfaces to a hard, dense finish with corners, intersections,
and terminations slightly rounded.
G. Equipment Bases and Foundations: Provide machine and equipment bases and foundations
as shown on Drawings. Steel-trowel surfaces to a hard, dense finish with corners, intersections,
and terminations slightly rounded.
1. Set anchor bolts for machines and equipment at correct elevations, complying with
diagrams or templates from manufacturer furnishing machines and equipment.
3.06 CURING AND PROTECTION
A. Utilize curing methods that are compatible with floor finish installation recommendations and
that are approved by floor finish manufacturer and installer.
B. Comply with requirements of ACI 308. Immediately after placement, protect concrete from
premature drying, excessively hot or cold temperatures, and mechanical injury.
C. Maintain concrete with minimal moisture loss at relatively constant temperature for period
necessary for hydration of cement and hardening of concrete.
1. Normal concrete: Not less than 7 days.
D. Surfaces Not in Contact with Forms:
1. Start initial curing as soon as free water has disappeared and before surface is dry. Keep
continuously moist for not less than three days by water-saturated sand, water-fog spray,
or saturated burlap.
2. Begin final curing after initial curing but before surface is dry.
a. Moisture-retaining cover: Seal in place with waterproof tape or adhesive.
b. Curing compound: Apply in two coats at right angles, using application rate
recommended by manufacturer. Contractor verify compatibility with specified floor
finishes.
3.07 FIELD QUALITY CONTROL
A. An independent testing agency will perform field quality control tests, as specified in Section
01400.
B. Provide free access to concrete operations at project site and cooperate with appointed firm.
C. Tests of concrete and concrete materials may be performed at any time to ensure conformance
with specified requirements.
