01043.01   DESCRIPTION

This work involves On-Call Contracting for Patching for the furnishing of labor, equipment, and materials in order to perform various items of patching work identified in the proposal form.  This work is intended for repairs where time does not permit the work to be included in a regularly scheduled letting and an emergency letting is not justified.

These contracts will be based on geographical areas or Districts.  The Contracting Authority will determine the need for the work and quantities to be performed.  The bidder submits a bid based upon single units of work and the low bid will be determined based on a calculation of the unit bid multiplied times the units of work determined by the Contracting Authority.  The initial bids may be used for numerous contracts over a 12 month period beginning with the date of letting.
