BACKGROUND:
On January 9, 2024, City Council approved a resolution authorizing the City Manager to execute a professional services agreement with Halff Associates, Inc. for engineering services related to the site development feasibility study for the City-owned property located near the intersection of PGBT and I-35E, now called the District 35E Property, in a total amount not to exceed $560,000.00.
On March 6, 2024, the contract was negotiated and executed in an amount of $537,000.00. The original scope provided for one site development analysis.
Contract Amendment No. 1 provided arborist services to meet the City’s Tree Preservation Ordinance while performing geotechnical analysis of the property and was executed on September 9, 2024, and increased the contract total to $547,000.00, leaving $13,000.00 available for future change orders.
Contract Amendment No. 2 will provide additional services, including an updated Traffic Impact Study, Additional Development Option, and Water System Impact Modeling. The total cost of the amendment is $85,000.00, requiring an additional $72,000.00 added to the contract.
FINANCIAL IMPLICATIONS:
Funding for these services will come from the TOD and Utility funds and is currently available.
Staff is proposing this contract amendment with a total amount not to exceed $72,000.00.
