Measurement and payment for contract work will be made only for and under those pay items included in the SCHEDULE OF ITEMS. All other work and materials will be considered incidental to and included in the payment of the pay items in the

SCHEDULE OF ITEMS.

1.2 – Payment

One of the following methods of measurement for determining final payment is DESIGNATED on the SCHEDULE OF ITEMS for each pay item.

(a) Designed Quantities (DQ): These quantities denote the final number of units to be paid for under the terms of the contract. They are based upon the original design data available prior to advertising the project. Original design data include the preliminary survey information, design assumptions, calculations, drawings, and the presentation in the contract. Changes in the number of units of the originally contemplated work will not be made unless authorized under one or more of the following conditions:

(1) As a result of changes authorized by the Contracting Officer in the originally contemplated work. Minor changes to adjust balance points, etc., will not be considered changes in quantities.

(2) As a result of the Contracting Officer determining that errors exist in the original design data used to determine designed quantities, that cause a pay item to change by 15 percent.

(3) As a result of the Contractor submitting to the Contracting Officer a written request showing evidence of errors in the original design data used to determine design quantities that cause a pay item total to change by 15 percent or more. The evidence must be verifiable and consist of calculations, drawings, or other data that show how the designed quantity is believed to be in error.

Final payment will be made for the designed quantities at the unit price shown in the SCHEDULE OF ITEMS, subject to the Variation in Quantities Provision.

(b) Actual Quantities (AQ): These quantities are determined from measurements of completed work.

01103 - 2

(c) Lump Sum Quantities (LSQ): These quantities denote one complete unit of work as required by or described in the contract, including necessary materials, equipment, and labor to complete the job. They will not be measured.

For all project mixed concrete, water shall not be added later than 15 minutes from start of mixing. For transit-mixed or agitated concrete, such water may be added upon arrival at the job site. Adding water beyond these conditions constitutes retempering which will not be allowed. When water is added, an additional 20 revolutions at mixing speed is required.

(b) Admixtures: Air-entraining admixtures shall not be added after the start of mixing.

3.1 - Construction

(a) Excavation: Excavation shall be made to the required dimensions to permit the installation and bracing of the forms. The foundation shall be compacted to a firm even surface. All soft, yielding material shall be removed and replaced with acceptable material.

(g) Placement: Concrete shall be discharged into the forms within 1-1/2 hours after the introduction of the cement to the aggregate. Retempering concrete shall not be permitted. The cement shall be added to the mixer at the jobsite whenever this condition cannot be met.

(h) Temperature: Concrete shall not be mixed or placed when the daily minimum atmospheric temperature is, or is expected to be, less than 40 degrees F unless adequate provisions are made to protect the concrete. No concrete shall be placed when the concrete temperature reaches 90 degrees F.

(i) Consolidation: Concrete shall be placed to avoid segregation. High-frequency internal vibrators shall be used for consolidating concrete in the forms. Vibrators

03301 - 5 shall be operated to produce concrete free of voids, but shall not be held so long in one place as to result in segregation or formation of laitance on the surface.

(k) Finishing: For the purpose of matching adjacent concrete finishes or for other reasons, the CO may permit other methods of finishing than those specified. No plastering will be permitted.

(l) Concrete Placement: Notify the CO a minimum of 24 hours prior to placement.

Place concrete in the forms as near final position as practical in a manner which will prevent segregation or loss of materials.

Place concrete in maximum 18" horizontal layers.

Immediately after placing, thoroughly compact concrete with mechanical vibrators.

Provide minimum of two vibrators. Provide minimum of two power sources unless commercial power is available at site. Hand tamping, when permitted, will be approved in writing by the CO.

Place each concrete section in a continuous operation, such as slab, footing, columns.

Do not drop concrete freely more than 4 feet.

Do not place concrete in water or allow water to rise over freshly placed concrete until a set is sufficient to prevent damage.

Backfill shall be readily compactable material free of frozen lumps, chunks of highly plastic clay, or other objectionable material. Rocks larger than 3 inches in diameter shall not be used within 1 foot of the structure.

(n) Protection from Rainfall: Protect flat work during rainy periods with adequate waterproof covering. Support covering so that finishing may be performed and initial set obtained without damage. Dragging of tarpaulins or other covering across unset concrete will not be permitted.

(o) Curing: Commence curing and protection of concrete immediately after completion of the finishing. Cure Type I and Type II cement for 7 days

03301 - 6 continuously. The work shall be moistened and kept moist during this time, or curing shall be accomplished by the use of membrane-forming curing compound.

(p) Cold Weather Concreting and Curing: When the descending air temperature at the project falls below 40 degrees F the Contractor shall cease placing concrete unless the procedures described below are followed. Normal concreting operations may resume when the ascending temperature at the site exceeds 40 degrees F.

Provide cover and heating equipment sufficient to maintain the temperature of the concrete at not less than 50 degrees F for a period of period of 3 days for Type I and Type II cement. Maintain the temperature at not less than 50 degrees F for a period of 2 days for Type III cement or when one additional sack of Type I or Type II cement is added.

Provide additional protection to prevent the concrete temperature from dropping more than 40 degrees F in the 24 hour period following the required protection period.

Keep concrete and forms wet. Remove and replace any concrete damaged by frost or freezing when directed by the CO.

(q) Hot Weather Concreting and Curing: If curing temperatures as placed are expected to exceed 75 degrees F, placing and curing shall be in accordance with

ACI 305.

The accepted quantities will be included in other contract items.
