ADMINISTRATIVE COMMENTS:
This project consists of constructing Corporate Drive from Railroad Street to just west of Holford’s Prairie Road, a four - lane divided roadway over the Elm Fork of the Trinity River including storm sewer improvements, a new water line, relocating a sanitary sewer line, a new sidewalk, a multipurpose trail, streetlights, and landscaping. Construction for Segments 2 & 3, including a half mile long bridge over the Elm Fork Trinity River, was bid and a contract was awarded to Sundt Construction, Inc. on December 4, 2023, with an anticipated start of February 5, 2024. During design, the length and scope of the bridge component became much larger than anticipated and it became apparent that the City would need to hire a third-party inspector to inspect the bridge and associated retaining walls as those services are outside the expertise of the City’s inspection staff. Staff reached out to the design consultant Halff Associates, Inc. to negotiate amendment #5 in the amount of $684,896 to add construction inspection and some administrative services for the bridge and associated retaining walls.
RECOMMENDATION:
That the City Council approve the Agreement as set forth in the caption above and authorize the City Manager, or her designee, to execute the agreement.
