Project Overview

The first phase of the upgrade began in late December 2018 and consisted of a plumbing scope and an HVAC scope. On the plumbing side, Notch removed the existing plumbing systems and miscellaneous gas lines. Once the old systems were removed, the team installed and modified all natural gas lines including high pressure gas. Next, a new 150 ton process chiller was installed. The HVAC side was a little more extensive in this first phase. The slab storage where the special rubber for the balls is stored needs to be stored in a humidity controlled environment. To ensure that the rubber is stored at the correct precise temperature and humidity, the Notch team installed make-up air units, unit heaters, roof top units and associated ductwork, grills and diffusers as well as a Munter’s Environment Control rooftop unit for the rubber storage room

Highlights & Challenges
  • In December 2018, Notch was hired by Columbia Construction to perform Plumbing and HVAC upgrades during Phase 1 of the Rubber Mixing Project at the Callaway Golf manufacturing facility in Chicopee, MA.
  • The location of the new system was shifted shortly after the project began due to space constraints as well as several re-designs involved including the addition of branched valves.
