Illinois Department of Military Affairs Freeport Armory Upgrades

Project Summary

Hanson provided project management, mechanical and electrical engineering for upgrades to the Illinois Army National Guard’s 33,689-square-foot, one-story Freeport Armory, constructed in 1958. The project included mechanical systems updates, such as replacing the heating system, installing controls, upgrading the plumbing system in the restrooms and electrical system upgrades.

A geothermal variable refrigerant flow (VRF) system and dedicated outdoor air unit with energy recovery serves a majority of the rooms, while a packaged, single-zone rooftop unit was installed to condition the drill hall. The vehicle maintenance bays received a new vehicle exhaust and makeup air system, and the kitchen upgrades included a new exhaust hood and makeup air unit. A new building automation system was installed with capability for remote access.

The scope also involved abatement of asbestos-containing materials, performed by a subconsultant; replacing ceilings; and painting.
