The estimated quantity is provided for quotation and planning purposes. The actual quantity awarded may be more or less, depending upon funding availability.

The Government will establish the funded quantity at the time of award. Payment will be made only for material delivered and accepted by the Government.

1.2 Site Visits: Quoters are encouraged to visit the delivery area and inspect existing site and access conditions before submitting a quotation. Quoters should pay particular attention to the unpaved access roads and limited availability of turnaround areas for large trucks.

To arrange a site visit, contact Sarge Vasquez at (956) 552-1556. Site visits may be scheduled Monday through Friday between 8:00 a.m. and 3:00 p.m.

PART 2: MATERIAL REQUIREMENTS:

2.1 Base Material

A. The Contractor shall furnish and deliver an estimated 1,500 tons of naturally occurring caliche suitable for use as flexible roadway base material. “Caliche” means a naturally occurring calcareous material composed primarily of calcium-carbonate-cemented soil or aggregate.

B. The material shall be graded to 1.5 inches minus and suitable for use as roadway base material.

C. The material shall be free from trash, vegetation, organic matter, and other foreign or deleterious material.

D. The quoter shall identify in its quotation the specific pit or quarry from which the proposed material will be obtained, including the source name and location.

2.2 Inspection and Rejection

The Government reserves the right to inspect the proposed material at its source and upon delivery. Government review or inspection of the source does not relieve the Contractor of responsibility for furnishing material that complies with the contract requirements.

Material that does not comply with the contract requirements may be rejected. The Contractor shall remove and replace rejected material at no additional cost to the Government, including all associated loading, hauling, removal, and disposal costs.

PART 3 – DELIVERY AND PLACEMENT
