Remove and replace soft or unsuitable material with approved material. Bring low sections, holes, or depressions to the required grades with approved material, shape the entire sub-grade to line, grade and cross , and thoroughly compact as specified.

Footings shall rest on undisturbed soil or compacted fill. In the event of over excavation for footings, over excavated portion shall be filled with concrete to correct elevation. Such concrete will be the same quality as that specified for footings.

3.2 – Preparation For Concrete Placement

A. Place embedded items, and expansion strips as indicated; maintain items securely in place. The Contractor shall give reasonable and adequate advance notice of concrete placement to all subcontractors and concerned parties who must place items to be embedded in or pass through the concrete to be poured, e.g. pipes, anchor bolts, sleeves, reglets, casings, etc., as shown on the drawings or otherwise required. Notify Government immediately of any conflict with structural elements.

B. Water shall be removed from place of deposit before concrete is placed unless otherwise permitted by the Government. All laitance and other unsound material shall be removed from hardened concrete before additional concrete is placed.

C. Screeds shall be rigidly secured in place. When the formwork is cambered, screeds shall be set to a like camber to maintain the proper concrete thickness.

D. Upon completion of preparatory operations, but prior to placement of concrete, Government shall be notified for observation minimum 24 hours prior to commencement of concreting operations. No concrete shall be placed without notification. The Government may regard preparatory work unacceptable if he has not had reasonable opportunity for such observation.

3.3 – Formwork

A. Formwork shall be structurally sound and rigid and shall conform in section and dimension to the drawings or plan. Forms are subject to the approval of the Government. Oil forms each time they are used.

B. Shoring and forms shall be cleaned of all loose dirt and other foreign matter. Dampen dry soil and forms just prior to pouring. Avoid excessive watering.

3.4 – Reinforcement

A. Reinforcing Steel: ASTM A615, 60 ksi yield grade, as noted on drawings; deformed billet steel bars, unfinished.

B. Welded Steel Wire Fabric: ASTM A185 plain type; in flat sheets; unfinished.

C. For spacing refer to drawings.

3.5 – Accessory Materials

A. Tie Wire: Minimum 16 gauge annealed type.

B. Special Chairs, Bolsters, Bar Supports, Spacers Adjacent to Weather Exposed Concrete Surfaces: Plastic coated steel type; size and shape as required.

3.6 – Joints

Joints not indicated on the drawings or plans shall be so made and located as to least impair the strength of the structure, while reducing the effects of shrinkage. The location of joints not indicated on the drawings or plans are subject to the approval of the Government.

Install pre-molded expansion joints if indicated on the drawings or plans. Expansion joint strips shall be installed to the full depth of the joint. Where caulked expansion joints are indicated on the drawings, set the top of expansion joint strips down from the finished top surface of slabs to the depth required to receive the caulking.

3.7 – Placing Concrete

A. Concrete shall be deposited as nearly as practicable in its final position to avoid segregation due to re-handling or flowing. The placing of concrete shall be carried on at such a rate that concrete is at all times plastic and flows readily into the spaces between the bars. No concrete that has been contaminated by foreign material shall be used, nor shall re-tempered concrete be used unless approved by the Government.

B. When placing is once started, it shall be carried on as a continuous operation until placement of the panel or section is completed. When construction joints are necessary, they shall be made as specified herein.

C. No concrete shall be dropped freely into place from a greater height than four feet.

Tremies shall be used for placing concrete where the drop is in excess of such height.

D. All concrete shall be thoroughly consolidated by suitable means during placement. It shall be thoroughly worked around reinforcement and embedded fixtures and into the corners of the forms. Vibration shall be transmitted directly to the concrete; in no case shall it be transmitted through the forms. The vibration shall be sufficiently intense to cause the concrete to settle readily into place and to visibly affect the concrete over a radius of at least 18". Vibrators shall not, however, be used to transport concrete or force concrete to flow horizontally. Vibration shall be supplemented by manual forking or spading adjacent to the forms on exposed faces in order to secure smooth, dense surfaces. If, for any reason, the surfaces or interiors have voids or are in any way defective, such concrete shall be repaired as directed by the Government, and no defective work shall be patched or repaired without the prior inspection and approval of the Government.

E. Slump:

1. Concrete samples shall be measured for slump in accordance with ASTM C143. The slump of the concrete shall be the minimum that is practicable.

2. In any case, the slump shall not exceed 4-1/2" without the expressed approval of the Government.

3.8 – Hot Weather Requirements

Concrete pours during hot weather should be scheduled for early morning hours to the maximum extent possible in order to permit finishing operations to be completed by noon.

3.9 – Cold Weather Requirements

A. Adequate equipment shall be provided for heating concrete materials and protecting concrete during freezing or near-freezing weather. No frozen materials or materials containing snow or ice shall be used.

B. All reinforcement, forms, fillers, and ground with which the concrete is to come in contact shall be free from snow or ice. Whenever the temperature of the surrounding air is below 40°F or higher after placement. Adequate means shall be provided for maintaining this temperature for 4 days. When high-early-strength concrete is used, a temperature of at least 45°F shall be maintained for 3 days. In either case, any additional time necessary to ensure proper curing of the concrete shall be provided as directed by the Government. The housing, covering, or other protection used in connection with curing shall remain in place and intact at least 24 hours after the artificial heating is discontinued. No dependence shall be placed on salt or other chemicals for the prevention of freezing.

C. Do not permit traffic over concrete until 75 percent design strength of concrete has been achieved.

3.10 – Removal of Forms

Forms shall be removed in such a manner as to ensure the complete safety of the structure.

3.11 – Finishing

Concrete slab shall have a Heavy Broom Finish.

3.12 – Cement Mortar

Cement mortar for the repair of imperfect concrete work, the filling of holes left by form bolts and ties, and the filling of voids around piping through concrete shall consist of cement and sand mixed in the same proportion as used for the concrete being repaired, with only sufficient water to give the required consistency, but in no case shall the water-cement ration be more than that specified for Class "A" concrete. Mortar that has not been placed within 30 minutes of mixing shall be discarded.

3.13 – Curing

Concrete shall be protected against loss of moisture, rapid drying, or temperature changes, mechanical injury or injury from rain or flowing water for a period of at least seven days in accordance with requirements of ACI 308 and ACI 305, as specified herein. Curing shall commence as soon as free water has disappeared from the surfaces after finishing.

3.14 – Defective Materials And Concrete

Concrete work shall be considered defective if not formed in accordance with the requirements of the drawings and specifications. Concrete may be judged to be unacceptable if it is not true to intended line, grade or plane, or contains sand streaks, objectionable joints, excessive pitting or dusting, voids or rock pockets detrimental to structure or finish, or which shows other irregularities, marking or deficiency including improper strength.

Defective concrete work shall be removed and replaced with new concrete acceptable to the Government, unless suitable correction of defects may be otherwise accomplished as authorized by the Government, and without additional cost to the Government.

3.15 – Protection Of Completed Work

During the curing period, protect the concrete from damaging mechanical disturbances, water flow, loading, shock, impact and vibration.

3.16 – Cleaning

After the concrete work is complete, carefully remove all excess concrete and all protective materials, expose the aggregate, and remove all mortar and other foreign materials. All concrete inserts, anchor bolts, etc., shall be cleaned of all concrete after forms are removed.
