Edison Middle School Roofing Replacement - Opinion of Probable Project Costs
This document is a pre-design phase opinion of probable project costs prepared by Andrade Architects LLC for the City of Meriden, Connecticut, regarding the roofing replacement project at Edison Middle School located at 1355 North Broad Street. The scope encompasses complete removal and replacement of existing roofing systems covering approximately 111,920 square feet with either EPDM low-slope membrane, PVC barrel-vault membrane, or thermoplastic polyolefin roofing, including removal of deteriorated roof decking, installation of new roof insulation, flashings, roof accessories, and sheet metal components. The project is anticipated to bid in late spring 2025, with a mandatory pre-bid meeting scheduled for April 15, 2026, and electronic bid submission deadline of 11:00 am on May 6, 2026. The contract establishes a substantial completion date of 15 days following the Notice to Proceed with final completion 15 days thereafter, and includes liquidated damages of $2,200 per calendar day for failure to meet the stipulated contract period. The contractor must provide a twenty-year, non-prorated, no-dollar-limit edge-to-edge warranty from the membrane manufacturer with a minimum 130 mph wind rider and maintain full-time on-site supervision throughout the project duration.
The probable total project cost is estimated at $5,946,600, comprising probable construction costs of $5,502,700 (at $49.17 per square foot) and probable owner costs of $443,900 (at $3.97 per square foot), yielding a combined cost per square foot of $53.13. Eligible costs total $5,346,900 while ineligible costs are estimated at $599,700. The estimate includes general conditions at 10 percent, contractor overhead and profit at 10 percent, bonds at 2 percent, a pre-design bidding contingency of 15 percent, and a construction contingency of 5 percent. Owner costs include professional services fees, on-site project representation, and miscellaneous expenses. The project requires a 25 percent Small Business Enterprise set-aside and a 6.25 percent Minority/Women/Disabled Business Enterprise set-aside of the state-funded portion. Prevailing wage requirements apply under Connecticut General Statutes Section 31-53, with certified payroll submissions required monthly for state determinations. Each bid requires a bid bond of 10 percent of the total bid amount, and the awarded contractor must provide Labor and Material Payment Bonds and a Performance Bond for 100 percent of the contract price.
