Summary

This is a set of project drawings and bid documents for the J. E. Smith Library Chiller Replacement project at Eastern Connecticut State University in Willimantic, Connecticut. The project involves the removal and replacement of roofing, roof drainage systems, structural steel support framing, and rooftop-mounted air-cooled chillers serving the library's chiller mezzanine area. The scope includes demolition of two existing 200-ton air-cooled chillers and installation of new MULTISTACK Model ACF240MNHCE 225-ton air-cooled chillers, end-suction chilled water pumps, variable frequency controllers, hydronic specialties including an expansion tank and air separator, new roof curb and rail systems, and new roof drainage with associated piping, wiring, and controls. Bids are due August 4, 2026, with construction scheduled to begin on or before September 23, 2026, and substantial completion required by May 1, 2027—a 227-calendar-day duration. Liquidated damages are assessed at $300 per calendar day for schedule delays. Bidders must pre-qualify under Connecticut General Statutes Section 4a-100 in General Building Construction (Group C), Mechanical (HVAC) Contractor, and Structural (Iron, Structural & Misc Metal) Contractor classifications.

The estimated contract value does not exceed $3 million, structured as a lump-sum base bid. The project includes a 25% Connecticut Registered Small Business Set-Aside subcontractor participation requirement, of which 25% must be woman or minority-owned. Bidders must submit a 10% bid bond or certified check with bids firm for 60 days. Contractors must perform not less than 30% of the work with their own forces and comply with prevailing wage requirements under Connecticut General Statutes Section 31-53. Performance and labor/materials payment bonds, each equal to 100% of the total bid price, are required within ten days of award. All work must comply with the 2022 Connecticut State Building Code, AISC 360-16 structural standards, ASME pressure vessel codes, and FM Global roofing system requirements. Bids are submitted electronically through the Eastern Bid Portal, with written questions due prior to the portal-specified deadline and responses distributed via addendum.

VERIFICATION OF EXISTING CONDITIONS PRIOR TO THE START OF WORK.

2. THE CONTRACTOR SHALL VERIFY THE EXTENT OF DEMOLITION AND CONFIRM CONNECTION POINTS OF EXISTING COMPONENTS TO REMAIN IN THE FIELD. BEGINNING OF DEMOLITION WORK MEANS CONTRACTOR ACCEPTS EXISTING CONDITIONS AND FULLY UNDERSTANDS SCOPE FOR CONNECTION TO EXISTING. PREMATURE OR EXCESSIVE DEMOLITION OR FAILURE TO RETAIN COMPONENTS OF THE SYSTEM SHALL RESULT IN THE CONTRACTOR PROVIDING REPLACEMENT AT NO ADDITIONAL COST TO THE OWNER.

3. THE CONTRACTOR SHALL NOTIFY ECSU FACILITIES MANAGEMENT & PLANNING A MINIMUM OF 2 WEEKS PRIOR TO ANY UTILITY SHUTDOWN AND A MINIMUM OF 48 HRS PRIOR TO START OF ANY WORK.
