WATER SYSTEM DEFINITION OF BID ITEMS

SECTION 012200

DEFINITION OF BID ITEMS

PART 1 - GENERAL

1.1 SUMMARY

A. The intent of this section is to explain, in general; what is and what is not included in a bid item; the limits or cut-off points where one bid item ends and another begins; and method of measurements and basis of payment for work items listed in the Bid Item

Schedule.

B. Work:

1. Furnishing all labor, materials, equipment, and other incidentals necessary to successfully complete the project or any portion of it, and carrying out all duties and obligations imposed by the contract on the Contractor.

2. For each individual item listed here and in the Schedule of Items, payment shall be full compensation for all work related to the particular item in accordance with these specifications, as shown on the drawings, and as staked in the field.

3. Measurement and payment for contract work shall be made only for and under those pay items included in the Schedule of Items. All other work and materials shall be considered incidental or as included in the payment for items shown.

1.2 DETERMINATION OF QUANTITIES

A. The contractor shall perform, or cause to be performed, all measurement of quantities of materials incorporated into the work processes that are to be measured under the provisions of the contract.

B. Quantity Measurements:

1. The Contractor shall make all measurements for computation of quantities for all work items except those specified for payment by Designed Quantity (DQ) or

Lump Sum Quantity (LSQ).

2. The contractor shall compute the quantities for periodic progress payments; the

Contracting Officer shall compute the quantities for the final payment based on measurements taken by the Contractor.

3. All Contractor measurements are subject to verification.

4. The Contractor shall submit all field notes, calculation sheets, and other data used to determine quantities.

5. The Contractor shall certify in writing as to the accuracy of the measurements and computations submitted.

C. The following measurements and calculations are used to determine contract quantities.

LOST LAKE CAMPGROUND 012200-2

1. For individual construction items, longitudinal and lateral measurements for area computations shall be made horizontally or corrected to horizontal measurement unless otherwise specified. Measurements for geotextiles, netting and erosion control blankets shall be along slope lines.

2. The average end area method shall be used to compute volumes of excavation or embankment. However, if in the judgment of the Contracting Officer (CO), the average end area method is impractical, measurement shall be made by volume in hauling vehicles or by other three dimensional methods.

3. Structures shall be measured according to neat lines shown on the drawings or as altered by the Contracting Officer, in writing, to fit field conditions.

4. For items that are measured by the linear foot, such as pipe culverts, fencing, guardrail, and under drains, measurements shall be made parallel to the base or foundation upon which the structures are placed. Pipes shall be measured along center of invert.

5. For aggregates weighed for payment, the tonnage shall not be adjusted for moisture content, unless otherwise provided for.

6. For standard manufactured items—such as fence, wire, plates, rolled shapes, pipe conduits—identified by gauge, weight, section dimensions, and so forth, such identifications shall be considered the nominal weights or dimensions.

Unless controlled by tolerances in cited specifications, manufacturer’s tolerances shall be accepted.

1.3 UNITS OF MEASUREMENT

A. Payment shall be by units defined and determined according to U.S. Standard measure and by the following:

B. Lump Sum: Do not measure directly. The bid amount is complete payment for all work described in the contract and necessary to complete the work for that item.

C. Where tolerances are shown in the contract, they are intended to define reasonably close conformity. Adjustments of horizontal or vertical alignment, within the tolerances specified in this contract, or shifts of balance points up to 100 feet shall be made by the contractor as necessary to produce the designed roadway sections and to balance earthwork. Such adjustments shall not be considered as “Changes.”

PART 2 - METHOD OF MEASUREMENT

2.1 GENERAL

A. One of the following methods of measurement for determining final payment is designated on the Schedule of Items for each pay item:

B. LUMP SUM QUANTITIES (LSQ)

LOST LAKE CAMPGROUND 012200-3

1. 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 shall be measured complete and in-place.

PART 3 – DEFINITION OF BID ITEMS

3.1 SCHEDULE OF ITEMS

A. Contractor shall provide item pricing for all items listed in the Schedule of Items.

3.2 DESCRIPTION OF BID ITEMS
