Building the Park Boulevard extension between FM 2514 and State Highway 78 is turning up surprises, and Collin County commissioners are being asked to pay for them over two straight Monday meetings.
On Monday, Oct. 19, the Commissioners Court's consent agenda includes a seventh amendment to the county's design and inspection contract with Halff Associates. It would add $346,756.89, raising the contract to $3,920,707.89. A week later, on Oct. 26, a fourth change order to the construction contract with RPMx Construction would add $202,367.86, bringing that contract to about $43.1 million.
Both would be paid from the county's 2023 road bond.
Why the inspection contract is growing
The county engineering department's memo says work on the road has run into unforeseen issues, including underground infrastructure and coordination with the North Texas Municipal Water District, the CPKC railroad, Oncor and residents. That took more of Halff's staff time to monitor and inspect the job.
The hours left under the current contract would carry the project to about 75% complete, the memo says.

The memo notes the hours are estimates and that the firm will not bill for time when its staff is not needed.
