Analysis
On June 4, 2019 the City Council awarded the Construction Manager at Risk (CMAR) contract to Hill & Wilkinson General Contractors (19-9024) for pre-construction services in the amount of zero dollars ($0). This award provided for CMAR services including development of project estimates, preliminary construction schedules, value engineering proposals and constructability review during the Design Phase.
Current Change Order/Amendment No. 2 in the amount of $109,179.10 is divided as follows:
$7,980.98 for electrical panel LA-4 coordination with existing conditions
$94,410.97 for electrical upgrades of existing equipment in order to meet all code requirements
$528.84 for minor adjustments to landscape and civil engineering designs to coordinate both scopes
$2,706.35 for change in length of HVAC slot diffusers required to allow proper air flow
$3,551.96 for replacement of existing fire alarm strobes in City Hall West in order to allow new overall fire alarm system for all three (3) connected City Hall buildings to communicate seamlessly and report appropriately to the Grand Prairie Fire Department
Change Order/Amendment No. 1 in the amount of $6,215,173 was approved by City Council on December 17, 2019 (19-9613) and represented the Guaranteed Maximum Price (GMP) for the scope of work defined in the Rouch Architects Construction Documents package as competitively bid by Subcontractors to Hill & Wilkinson General Contractors. Costs above and beyond the Hill & Wilkinson portion of the project addressed in Change Order/Amendment No. 1 included previously approved Construction Manager pre-construction fees ($0) and an asbestos remediation allowance ($30,000); 5% contingency ($310,759); allowance for FF&E ($1,200,000); allowance for IT/data design and installation ($95,000); allowance for A/V equipment ($200,000); allowance for door access and security systems ($95,000); allowance for Oncor Electric power line relocation ($125,000); plus an allowance for construction testing ($25,000), all of which total the overall project budget of $8,295,932.
Items applicable to performance by the Construction Manager at Risk (CMAR) will be incorporated into the current Hill & Wilkinson General Contractors contract for a revised total contract in the amount of $6,324,352.10. Percentage of change orders including the current Change Order/Amendment No. 1 is 1.76%.
