Project Overview
Heffron has delivered mechanical scope across MilliporeSigma’s Maryland life sciences operations, tying new equipment into live research and manufacturing environments without interrupting production.
The work spans the full utility backbone of the site — from rooftop heat rejection down through the central plant and out to validated process rooms — keeping cooling, high-purity water, and clean utilities reliable for sensitive research and biomanufacturing workloads.
Heffron continues to service the building today. What started as a build relationship is now an ongoing service partnership — the same crews who installed the cooling towers, chillers, high-purity water systems, and central plant equipment are back on site keeping it running years later. That’s the Heffron model: build it right the first time, then stay with the client to maintain it for the life of the facility.
