Minnechaug Boiler Addenda No. 1.pdf

This is an addendum to contract documents for a boiler replacement project at Minnechaug Regional High School in Wilbraham, Massachusetts, issued by Robt. W. Hall Consulting Engineers, Inc. on July 28, 2026. The addendum specifies critical operational constraints for the project execution: the school will remain in session and fully occupied during the contract period, with rigging operations over occupied spaces strictly prohibited. To accommodate these restrictions, three specific dates are designated as available for rigging activities during normal business hours: November 3, November 11, and November 25, 2026. This constraint significantly impacts project scheduling and logistics planning for bidders responding to the August 3, 2026 bid deadline.

The addendum addresses a key operational concern for a $125,000 estimated HVAC general contracting project involving the replacement of one boiler among five existing units at the school. Bidders must account for these limited rigging windows and occupancy restrictions when developing their project schedules and cost estimates. The constraint necessitates careful coordination with school administration and may require phased work sequences or alternative installation methodologies to maintain safety and minimize disruption to the educational environment during the school year.
