Analysis
On April 3, 2018 the City Council awarded the Construction Manager at Risk (CMAR) contract to Hill & Wilkinson General Contractors (18-7758) for pre-construction services in the amount of $5,000. This award provided for CMAR services including development of project estimates, preliminary construction schedules, value engineering proposals and constructability review during the Design Phase.
On December 18, 2018 the City Council awarded the Guaranteed Maximum Price (GMP) contract to Hill & Wilkinson General Contractors (18-8351) for the scope of work currently 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 this Change Order/Amendment include previously approved Construction Manager pre-construction fees ($5,000); previously approved survey studies ($4,750); previously approved parking provisions ($200); previously approved communication equip/maint ($14,101); previously approved communication & video ($185,144); previously approved construction funding ($10,245); previously approved design/engineering/construction/geotechnical fees ($1,943,107); 5% contingency ($600,000); budget allowance for owner-provided furniture/fixtures/equipment ($923,000); allowance for construction testing ($75,000); allowance for audio/visual provisions ($185,000); allowance for IT/data design and installation ($100,000); plus an allowance for door access and security systems ($110,000), all of which total the overall phase one project budget of $16,999,958.
However, the $75,000 allowance for construction testing approved in the December 18, 2018 agenda item was an estimate based on construction cost and anticipated extent of the scope of work. When the fully detailed estimate was received from CMJ, the amount was $106,347.13. This increased amount was due to the added level of testing requested by the City of Grand Prairie based on the soil characteristics associated with the specific construction site on which the new City Hall facility is being built.
With the initial geotechnical report having been generated by CMJ, it was important to maintain consistency throughout the project by engaging CMJ Engineering for construction testing from start to finish. CMJ’s knowledge of the soil conditions associated with the new City Hall construction site will serve as an irreplaceable resource as detailed construction issues and challenging conditions are encountered.
