Energy Savings Performance Contract (ESPC)

Location: Joint Systems Manufacturing Center (JSMC), Lima, OH
Client: Siemens Government Technologies (SGT)
Completion: 2018
Value: $8.7M

Highlights:

  • CMS self-performed installation of new steam piping connections at roof-top units
  • Air cranes used to remove existing 19,000-lb. units from the roof and then lift and place new replacement units on the roof
  • Zero OSHA-recordable incidents, despite unique site conditions/safety hazards (e.g., fall protection, cranes/air lifts/rigging, lock out/tag out, etc.)
  • Work in operating manufacturing facility with minimal impact to facility mission

Scope

CMS was awarded a design-build turnkey contract to install 37 roof top steam-fired heat recovery units (HRUs) and a single large air handling unit (AHU) at the JSMC (aka Lima Army Tank Plant) in Lima, OH. The scope of work included the removal and demolition of the existing HRUs and associated piping, electrical services, controls, and appurtenances. CMS also supplied and installed controls with native BACnet connectivity to permit integration to a new facility-wide building management system on the new HRUs, as well as variable frequency drives (VFDs) on the HRUs and exhaust fans.

Following disconnection/demolition of the existing HRUs and AHU and placement of new roof curbs, new 19,000-lb. units were air lifted and placed on the roof of the facility using air cranes (specially equipped helicopters), where the waiting CMS crew reestablished new piping and electrical connections.

USACE Huntsville District has oversight of JSMC Lima – America’s last major tank factory. Built in 1941, the facility currently turns out 11 upgraded Abrams tanks a month. This project not only dramatically reduces the facility’s carbon footprint, but also is entirely funded by the energy savings resulting from the system upgrade..
