6-Attachment No. 6 - REQ-0009198 - Task Cost Matrix.xlsx

This is a Task Cost Matrix for REQ-0009198, Site Improvements at St. Aubin, Belle Isle, and Baby Creek CSO Facilities, a Michigan state and local contract opportunity for study, design, and construction assistance services at multiple combined sewer overflow facilities. The request encompasses twelve distinct tasks spanning the complete project lifecycle: Task A (Project Management), Task B (Study Phase), Task C (30% Design), Task D (60% Design), Task E (90% Design), Task F (Permitting), Task G (Final Bid Documents), Task H (Bidding and Negotiation Services), Task I.1 (Construction Management), Task I.2 (Resident Project Representation), Task J (Asset Management Services), Task K (Document Turnover), and Task L (Systems Operations and Maintenance Training). Each task includes provisions for direct labor with estimated hours across ten position categories, indirect costs with overhead percentages, other direct costs including equipment and travel, and subconsultant/subcontractor labor.

The cost matrix structure allows bidders to propose labor rates and hours for each task, calculate overhead and indirect costs as percentages, identify additional direct costs, and apply contract mark-ups separately for direct labor, indirect labor, and subconsultant/subcontractor services to arrive at total task costs. The matrix format enables transparent cost breakdown and comparative evaluation across qualified proposers, with the flexibility to accommodate varying fee structures and project delivery approaches while maintaining cost visibility and control throughout the multiple phases of facility study, permitting, design advancement, and construction support services.
