Agenda Item

Consider approving Change Order No. 4 in the amount of $41,558.79 for Chandler Road Phase 3B, a Road Bond Project in Precinct Four.

Background

Contract Item 341 “Dense-Graded Hot-Mix Asphalt (QC/QA)” allows for the adjustment of compensation paid to the contractor based on the quality of the hot mix asphalt pavement produced and placed on the project. Specific job control tests were run on the asphalt (see attached back-up documentation) to monitor the quality of the mix. Using the results of these tests in conjunction with TxDOT formulas as outlined in the specification, the Contractor was either awarded a bonus or assessed a penalty. This change order adds the pay items below to the contract in order to make these pay adjustments.

As required by Item 585 “Ride Quality for Pavement Surfaces”, this change order adds a pay item to adjust the amount of compensation to be paid to the contractor in proportion to the ride quality of the final asphalt surface on the project. An inertial profiler was used to measure and evaluate the profiles of the eastbound and westbound lanes on Chandler and the northbound and southbound lanes on CR 366. The Contractor was awarded a bonus for ride quality using the results of the profiles in conjunction with TxDOT formulas as outlined in the specification.
