E. Submittals. The supplier shall submit a signed letter of certification stating that materials supplied will meet the requirements of part 2 products. This letter of certification must be included with the quote. After award the Contractor shall submit their job mix gradation as required in table two of the referenced UDOT spec 02721.

1.2 REQUIREMENTS

A. Site Tour. A formal Site Tour will not be conducted. The Contractor should visit the site on their own, after contacting the Contracting Officer’s Representative (COR) Todd McDougall at 435.719.2160 to schedule their visit.

F. Offloading. The Contractor shall comply with the Park POC on offloading procedures and locations to facilitate the Park in pushing the material up into a pile or hauling the material to the jobsite.

PART 2 PRODUCTS

2.1 PRODUCT REQUIRMENTS

A. UBC. The UBC shall meet the requirements of UDOT spec 02721 part 2 Products (dated

January 1, 2008). The aggregate class designation for Table 1 may be A, B, or C, however the Park prefers class C. UDOT spec section 02721 is included in the statement of work as addendum 1.

PART 3 EXECUTION – N/A

PART 4 MEASUREMENT AND PAYMENT

4.1 UBC will be measured by the ton. The Contractor shall provide the Park POC with certified weigh tickets with each delivery. Payment will be made according to the price schedule (Part B on page 4 of the RFQ Solicitation).

4.2 Payment requests must be submitted electronically through the U.S. Department of the Treasury's Invoice Processing Platform System (IPP). "Payment request" means any request for contract financing payment or invoice payment by the Contractor.
