B. Schedule concrete placements so newly placed concrete will not be damaged by blasting or other operations.

C. Provide walkways and platforms for personnel and equipment at levels convenient for Work and to permit performance of operations necessary for concrete placement, consolidation, finishing, and curing.

D. Prepare earth foundations to receive concrete as follows:

1. Ensure earth foundations are clean, damp, and free from standing or running water, and loose particles or foreign matter.

2. Compact earth foundations in accordance with Section 31 23 00.

3. Maintain groundwater levels below subgrade until concrete has set.

4. Wet dry earth surfaces by sprinkling before placing concrete to minimize moisture absorbed from fresh concrete.

5. During concrete placement, ground surface shall be moist, but free from standing water, mud and debris.

E. Prepare sand, gravel, or crushed rock foundations to receive concrete as follows:

1. Place geotextile filter above sand, gravel or crushed rock.

2. Keep aggregate base or sand filler or drain material dewatered to prevent concrete materials from being deposited in water.

3. Place steel reinforcement and concrete as quickly as possible after placing geotextiles.

F. Before placing concrete, provide dewatering, runoff diversion, upstream debris containment systems and protection as needed to ensure proper and water-free environment suitable for concrete hardening and curing.

1. Do not place concrete if 15-day weather forecast indicates chance of rain.

2. Do not place concrete underwater or in spaces where standing water is present.

G. Concrete placement will not be permitted when, in City’s Representative’s opinion, jobsite conditions preclude proper placement, control, consolidation, and finishing.

H. Protect uncured concrete from exposure to rain, runoff or groundwater.

I. Prosecute Work so construction joints occur at locations shown on Plans and Working Drawings.

1. Construct concrete between joints in 1 continuous placing operation.

2. Refer to Section 03 15 00 for requirements for construction joints and expansion joints.

J. Cold joints shall be deemed to occur when concrete placement is interrupted so new concrete is neither incorporated integrally with previously placed concrete in opinion of City’s Representative nor keyed into place with preformed construction joints shown on Contract Documents or accepted Working Drawings.

1. Minimize cold joints.

2. Form and place vertical joints as construction joints wherever possible.

K. Prepare vertical surfaces of cold joints as follows:

1. Clean tooled joint surface of laitance, loose or defective concrete, and foreign matter by hydroblasting or sandblasting to expose aggregate.

2. Wash hydro-blast or sandblast surface with clean water.

3. Method of disposing of wastewater used to wash concrete surfaces shall cause no staining, discoloration, or deterioration of exposed surfaces of structures and improvements.

4. Coat joint surface with epoxy-bonding agent unless otherwise shown.

5. Wet joints not coated with bonding agent before placing concrete adjacent to joint.

L. Prepare horizontal surfaces of cold joints as follows:

1. Roughen horizontal surface with minimum ¼” amplitude profile for good bond.

2. Clean tooled joint surface of laitance, loose or defective concrete, and foreign matter by hydroblasting or sandblasting to expose aggregate.

3. Wash hydro-blast or sandblast surface with clean water.

4. Remove ponded water from surface of joints.

5. Method of disposing of wastewater used to wash concrete surfaces shall cause no staining, discoloration, or deterioration of exposed surfaces of structures and improvements.

6. Coat joint surface with epoxy-bonding agent unless otherwise shown.

7. Wet joints not coated with bonding agent before placing concrete adjacent to joint.

8. Cover horizontal joints, except expansion or contraction joints, with 1” layer of Class D mortar (1 part Portland cement – 2½ parts fine aggregate).

9. Limit water in mortar to that required to produce consistency similar to fresh concrete.

M. Notify City’s Representative in writing ≥ 24 hours before placing concrete.

1. Do not place concrete except when City’s Representative or their duly authorized representative is present.

N. Secure inspection of steel reinforcement and obtain acceptance by City’s Representative ≥4 hours before placing concrete,.

O. Before placing concrete, verify location of embedded items with affected trades.

1. Each trade having embedded items, including water stops within forms and affected by pour shall certify items are properly located, placed and braced.

2. Verify embedded items are firmly and securely fastened in place.

3. Embedded items shall be free of oil and other foreign matter such as loose coatings or rust, paint and scale.

4. Accuracy of placement of embedded items is Contractor’s responsibility.

5. Do not embed wood into concrete unless accepted in writing by City’s Representative.

6. Temporarily fill voids in sleeves, inserts, and anchor slots using removable materials to prevent concrete entry into voids.

7. Before placing concrete, provide written notice to City’s Representative and submit Preplacement checkout form similar to that in ACI SP2 described under “Submittals.”

8. Equipment needed to place and consolidate concrete shall be at placement site and in good operating condition.
a. Spare vibrators shall be available throughout concrete placement.

9. Do not use aluminum pipes, chutes, troughs, spouts or tremies for pumping, conveying or placing concrete.

10. Order of placement of concrete shall be acceptable to City’s Representative.

11. To minimize shrinkage effects, place concrete in units bounded by construction joints shown in Working Drawings.

12. Placement shall occur such that each unit shall cure ≥3 days before contiguous units are placed, except corner sections of vertical walls shall not be placed until the 2 adjacent wall panels have ≥7 days.

13. Moisten surfaces against which concrete will be placed with water immediately before placing concrete.
a. Remove ponded or excess water to leave surfaces moist but not flooded.

P. Concrete not placed within 10 minutes from time of leaving mixer shall be remixed before placing.

1. Concrete not placed within 15 minutes after mixing shall be removed from Work site and legally disposed of.

Q. Provide sufficient illumination in interior of forms so concrete at places of deposit is visible from deck or runway.

R. Do not place concrete when weather conditions prevent proper placement and consolidation.

S. Maintain temperature of concrete within the following ranges immediately before placement.

1. Concrete <12” thick: 55°F to 90°F

2. All other concrete: 50°F to 90°F

3. When concrete temperature exceeds 80°F, only set-retarding hydration stabilizing admixtures shall be used.

4. When concrete temperature exceeds 85°F, time between introducing cement to aggregates and discharge shall not exceed 45 minutes.

5. No additional compensation will be made to contractor for measures used to maintain concrete temperature within specified limits.

T. Schedule concrete placement during evening or morning hours, and provide ice, refrigerated mixing water, pre-cooled aggregate, shading, sprinkling and other means needed to conform to maximum temperature limits.

1. If ice is used, store ice at temperatures low enough to prevent forming lumps by refreezing particles.

2. Size of ice particles shall ensure ice completely melts before end of mixing time for each batch.
a. Do not use liquid nitrogen cooling.

U. Hot weather placement shall proceed as follows:

1. Comply with ACI 305R.

2. Do not mix or place concrete when atmospheric temperatures are ≥ 115°F, unless means are employed to cool aggregate and water and protect Work
