A. Performance Specifications
1) The successful respondent will provide delivery using the most cost-effective trucking

repaving, and (c) construction. The average value can be obtained based on historical
use and types of projects providing the performance specifications in #9 are met.
2) Previous contracts have shown little price difference in all types of asphalt. Therefore,
the unit price quoted shall provide delivery for Type B (292), Type C, and Type D hot mix
asphaltic concrete as per City of Denton Standard Specification.
3) Successful respondents will be required to meet performance specifications as
follows:
a. Twenty-four (24) hour* telephone to receive messages. The City will give 12 hours’
notice of intent to receive and attempt to give six (6) hours’ notice of cancellation.
b. Seven (7) calendar day* response time after vendor is contacted by the City to
provide experienced asphalt paving crew and laydown machine, rollers and trucks.
* The contractor is expected to respond to the initial contact* from The City within 2
hours during normal business hours. Normal business hours are Monday – Friday 7am-
4pm. If there is no response from a contractor within 2 hours, the City has the right to
call a secondary contractor. Secondary contractors must also respond to initial
contact within 4 hours, etc. If contractors cannot meet delivery deadlines, the City
reserves the right to call secondary vendors.
NOTE: The following are minimums:
c. Delivery of patching hot mix shall be at the rate of 48 tons over any 8-hour day or 8
tons per hour.
d. Delivery of hot mix for repaving shall be at the rate of 90 tons per hour.

every day.
Failure to meet performance requirements listed above could be considered in breach of
the contract.
