GENERAL NOTES AND TECHNICAL SPECIFICATIONS

General Information

Williamson County is seeking to purchase Type I/II and Type IL Portland Cement, from qualified companies and conforming to Texas Department of Transportation Departmental Materials Specifications DMS-4600 “Hydraulic Cement”, Effective date: October 2024 (Formerly DMS-4600 the Hydraulic Cement Quality Monitoring Program, or HCQMP).

The cement must be bid as Item Picked Up and Item Delivered separately for both bulk supply and bags. Location is an important factor in evaluation of Bids, due to transportation costs which must be taken into consideration. It is expected that the bagged cement will be picked up at plant site by Williamson County and bulk cement shall be delivered to the project site. However, there will be times when the County may require bagged material to be delivered. For this reason, the County is requesting separate bids for each item.

The County is not obligated to purchase any minimum amount, and the County may purchase any reasonable amount for the same unit price. Items will be ordered on an “As Needed” basis.

Williamson County reserves the right to award the bid in whole to one vendor or to award a contract on each separate item or combination of items as may be most advantageous to the County.

It is expressly understood and agreed that in case Williamson County should need any item(s) not available within the time frame needed from the successful vendor(s) during the term of this contract, the County reserves the right to purchase the item(s) from vendors other than the successful vendor(s) and shall not be in violation of any terms or conditions of said contract.

Provide three (3) references where like services have been performed by your firm. Include name of firm, address, telephone number and name of representative.
