Lee Mechanical was selected by the Waukesha Public Library to deliver a comprehensive $394,621 temperature controls retrofit within a busy, fully operational municipal facility. The project modernized an aging mix of pneumatic and DDC systems by upgrading the building to a unified Carrier i-Vu platform. 

Mechanical fitters installed new hot water control valves and performed full field verification to locate terminal units and valve points, as current mechanical drawings were unavailable after multiple remodels. 

The Controls Division completed installation, wiring, programming, and commissioning of the new system, carefully sequencing work to maintain comfort and minimize disruption during daily public operating hours.

Unique Challenges and Solutions

Lee Mechanical completed full field verification of terminal units, valves, and system configurations due to the absence of current mechanical prints. This detailed groundwork ensured accurate installation and helped the team avoid system conflicts throughout the project.

Working within a constantly occupied public library required strict noise control, phased scheduling, and close coordination with facility staff. Daily programs, peak traffic periods, and community activities influenced the sequencing of work to maintain comfort and minimize disruptions.

Migrating from a hybrid pneumatic/DDC system to a unified Carrier i-Vu platform also required careful integration and commissioning. The Controls Division followed a structured retrofit process that improved system reliability, accuracy, and long-term serviceability.

The project ultimately delivered a fully modernized controls infrastructure that improves energy management, enhances indoor comfort, and provides the library with a durable, future-ready system. Despite limited documentation and continuous public use, Lee Mechanical completed the work on schedule with minimal impact on daily operations.
