About this file
This is an Opinion of Probable Project Costs prepared by Andrade Architects LLC for the Meriden Public Schools in Meriden, Connecticut, dated December 10, 2024, for the Edison Middle School roofing replacement project. The project involves the removal and replacement of membrane roofing assemblies, hung gutters, and related sheet metal flashing on the existing school building located at 1355 North Broad Street in Meriden, Connecticut. The roof replacement work encompasses approximately 111,920 square feet and includes PVC membrane roofing options to return the building to a leak-free, low-maintenance condition. The work must comply with applicable Connecticut building codes and regulations, as well as State of Connecticut Department of Administrative Services Office of School Construction Grants & Review requirements for reimbursement. Bidding is anticipated for late spring 2025, with hazardous materials not suspected in the existing roof assemblies constructed in 2000.
The probable project cost is estimated at $5,946,600, comprising probable construction costs of $5,502,700 and probable owner costs of $443,900. Construction costs include roofing systems options with EPDM low-slope membrane ($1,755,300), PVC barrel-vault membrane ($542,300), roofing accessories ($48,800), sheet metal flashing and trim ($324,600), and selective demolition ($435,800). The estimate incorporates a 15 percent bidding contingency ($683,600), a 5 percent construction contingency ($262,100), general conditions at 10 percent ($369,300), contractor overhead and profit at 10 percent ($406,200), and bonds at 2 percent ($89,400). Owner costs include A/E professional services fees ($325,000), expanded A/E and other professional fees ($16,000), on-site project representation for five months ($50,000), and construction bid set printing ($1,000), with a 10 percent owner contingency applied. The cost per square foot for the probable project is estimated at $53.13, with eligible costs totaling $5,346,900 and ineligible costs totaling $599,700.
