C1 - Contractor Cost Workbook - Burton Perf Arts.xlsx

This is a Contractor Cost Workbook submitted for construction management services for the Burton Performing Arts project by Grand Rapids Public Schools in Michigan. The document outlines the estimated costs and staffing plan for a construction manager as constructor (CMc) delivery method, with preconstruction services scheduled from January 1, 2027, to November 15, 2027, and construction activities running from June 15, 2028, to October 15, 2028. The preconstruction phase spans 11 months (318 days) and the construction phase is estimated at 4 months (122 days). The contractor's cost workbook includes detailed staffing allocations, with a Senior Project Manager (Joe 'Example' Dirt) assigned 40 hours during both preconstruction and construction phases at a rate of $10.00 per hour.

The total estimated cost of work is $320,500. The cost breakdown shows general conditions totaling $810, comprised of $400 in labor costs for preconstruction services and construction personnel, and $10 in permits and insurance expenses. General conditions represent 0.25% of the total construction cost, and construction manager services are similarly estimated at 0.25% of the construction cost. The workbook stipulates that personnel rates include salaries and mandatory contributions such as employment taxes, insurance, and statutory benefits, with annual increases limited to 3% after December 31, 2025. The contractor is subject to prevailing wage rules, and general liability insurance may only be applied to the construction manager's fee rather than to the cost of work. No overtime rates are to be charged to the owner, regardless of actual hours worked by personnel.
