Measurement and Payment for contract work will be made only for and under those pay items included in the SCHEDULE OF ITEMS of this contract. All work, equipment, material, and incidentals shall be included in the bid price and payment for the appropriate related pay item.

FOR BID PURPOSES CONTRACTORS SHALL submit one lump sum as described in Section 01010, Part 1. The Contactor to whom the contact is AWARDED shall submit a project cost breakdown per schedule of items.

1.02 Method of Measurement: Following are the methods of measurement for determining final payment as designated on the Schedule of Items:

A. Designed Quantities (DQ)

1. 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 includes 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:

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

b. 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 10 percent or more.

c. 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 10 percent or more.

2. Final Payment for Designed Quantities: Final payment will be made for the designed quantities at the unit price shown in the Schedule of Items, subject to the provisions above.

B. Staked Quantities (SQ)

These quantities are determined from stake measurements prior to construction.

Angeles Crest Scenic Byway Projects DIVISION 1 Section 01025-2

C. Actual Quantities (AQ)

These quantities are determined from the measurements of the completed work.

D. Vehicle Quantities (VQ)

These quantities are measured in the hauling vehicles.

E. 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.

1.03 Determination of Quantities: Only actually completed and accepted work of the contract will be measured and determined as follows:

A. Area computations will be horizontal or corrected to horizontal plane.

B. Volumes of excavation or embankment will be by average end area or approved three-dimensional calculations. General grading will be by horizontal area and mean depth(s). With prior written approval, or when specified, measured haul vehicle volumes or certified scale weigh bills may be substituted.

C. Structural volumes will be to the neat lines SHOWN ON THE DRAWINGS, or to the dimensions of limits indicated in the specifications.

1.04 Units of Measurement: Units of measurement will be those shown in the

SCHEDULE OF ITEMS, and as defined in the specification sections. Accurate and approved measuring devices, appropriate to the unit, will be used for measuring.

A. Quantities other than job, each set, and the like will be measured to the whole amount.

B. Quantities such as job, each, set and the like, and subject to need for incrementing for partial payment, will be measured as a mutually acceptable percentage.

1.05 Payment: Payment will be made only for actual quantities completed and accepted, and measured as indicated above, or the items AS SHOWN ON THE SCHEDULE

OF ITEMS. Such payment will be at the Contract Unit Price for each Item as

SHOWN ON THE SCHEDULE OF ITEMS, and shall constitute complete and final payment for such work. Payment will be made for whole amounts or increments as indicated in Method of Measurement above.

1.06 Variations to Above: Variations may be permissible as agreed by Contracting
