C1 - Contractor Cost Workbook - Burton Perf Arts.xlsx

This is a Contractor Cost Workbook for Burton Performing Arts submitted to Grand Rapids Public Schools in response to a Construction Management Services Request for Proposal. The project utilizes a Construction Manager as Constructor (CMc) delivery method, with a preconstruction phase scheduled from January 1, 2027, to November 15, 2027 (11 months), and a construction phase from June 15, 2028, to October 15, 2028 (4 months). The workbook details staffing allocations and cost projections for the project delivery across both phases, with minimal personnel deployment beyond a Senior Project Manager assigned at a rate of $10.00 per hour allocated for 40 hours during preconstruction and 40 hours during construction.

The total estimated cost of work is $320,500, with total general conditions costs of $810, representing 0.25% of the construction cost. Staffing costs total $800, comprised of $400 for preconstruction services and $400 for construction personnel, while permits, insurance, and taxes are estimated at $10 for building permits. The workbook indicates this is a prevailing wage project with personnel rate increases limited to three percent annually after December 31, 2025. All costs are structured on a forty-hour work week basis, with the Construction Manager's personnel potentially working overtime but with overtime rates never charged to the owner. The submission shows minimal subcontractor and equipment/material costs, with reimbursable expenses totaling zero across all categories.
