PART 4 METHOD OF MEASUREMENT AND BASIS OF PAYMENT

4.01 METHOD OF MEASUREMENT

A. The ENGINEER may direct the CONTRACTOR to perform work that was unexpected under force account. The payment to the CONTRACTOR for such work is compensation in-full and will be determined as follows:

1. Labor: For the time that workers and their immediate working foremen are engaged specifically and solely in force account work, BOPU will pay the cost of those employees’ wages at the rates shown on payroll plus 66 percent to cover any overhead. Hours shall be measured to the nearest recorded one-half hour each day.

2. Materials: BOPU will pay for the actual cost of materials approved for use by the

ENGINEER and incorporated into the work, including transportation charges

(exclusive of equipment rentals), plus 15 percent. BOPU will not issue payment without receipt of invoices substantiating the material and transportation costs.

If materials are taken from the CONTRACTOR’S stock, provide a statement certifying that the materials were taken from stock, that the quantity claimed was used, and that the price and transportation claimed represent actual costs.

3. Equipment: BOPU will pay for the rental of equipment approved by the

ENGINEER. The ENGINEER requires fully operational equipment of a size and capacity to perform the work. The ENGINEER may approve the use of equipment not meeting this requirement if furnished by the CONTRACTOR at reduced prices that are mutually agreed upon. The CONTRACTOR and the

ENGINEER will agree on whether to use equipment already available on the project or to lease equipment. BOPU will pay for equipment based on actual hours of use, recorded to the nearest one-half hour each day. If the total period of operation within a day is less than one hour, the department will consider the time as one full hour. In determining payment rates, BOPU will pay for rental of the CONTRACTOR’S own equipment at rates given in the Rental Rate Blue Book for Construction Equipment, volumes 1-4, published by Equipment Watch, adjusted both regionally for Wyoming and for equipment age.

4. Invoicing: If the ENGINEER and the CONTRACTOR agree that an item of work requires a specialist, the administrative work may be paid for based on a

CONTRACTOR or subcontractor invoice. Specialist work includes an item of work or service requiring skills, tools, or equipment unavailable within the

CONTRACTOR’S or authorized subcontractors’ organizations. If a CONTRACTOR is required to perform specialized fabrication or machining in a shop facility away from the project, BOPU may accept the charges for that portion of the

CONTRACTOR’S work as an invoice billing to which 5 percent has been added.

BOPU will base its payment for specialty work or service on current market price. In all other instances, BOPU will not pay for invoicing or related administrative tasks.

5. BOPU will not pay additionally for items or services already covered by or inherent to the contracted scope of work (such as general superintendence, use of small hand tools, or the provision of storage facilities).

4.02 BASIS OF PAYMENT

A. Payment for any force account work will be made in whole following completion and acceptance of the work.
