Body
BACKGROUND
On June 26, 2019, the City Council authorized a professional services contract with Halff Associates, Inc. for the engineering design of a local street reconstruction project on 10th Street from Interstate Highway 35 to Clarendon Drive by Resolution No. 19-0983.
To minimize the construction impact of the 10th Street Project on the cemetery at 100 North Moore Street, the Landmark Commission requested an archeological survey of the slopes along the cemetery within the limits of the 10th Street Project. The archeological survey was submitted to the Texas Historical Commissions (THC) for review. The THC review comments requested for additional archeological survey and On-the-Ground survey of identified objects and Texas Antiquities Permit for construction and archeological monitoring during construction. Consequently, it is necessary to add the required archeological survey and construction monitoring services to the contract.
This action will authorize Supplemental Agreement No. 3 to the professional services contract with Halff Associates, Inc. to provide additional engineering and archeological survey services needed for 10th Street from Interstate Highway 35 to Clarendon Drive to mitigate potential risk to the cemetery at 100 North Moore Street.
Halff Associates, Inc. is a Richardson-based corporation and is a registered vendor with the City of Dallas.
If this action is delayed or deferred, the construction schedule could be delayed. Field conditions may also change, which will require modifications to the engineering design plans, requiring additional funding and time to address.
ESTIMATED SCHEDULE OF PROJECT
Began Design August 2019
