SHA Headquarters Complex Systems Renovation

Location: Hunt Valley, Maryland Client: Maryland State Highway Administration

JMT developed construction documents for mechanical and electrical modifications to the SHA Headquarters Building.

The Maryland State Highway Administration's (SHA) Headquarters building, located on 707 N. Calvert Street in Baltimore, MD, had recently undergone significant architectural and engineering reconstruction. In order to complete the electrical and mechanical portions of the renovation, SHA desired a consultant service to develop construction documents for these modifications. JMT was contracted to prepare documents outlining the following modifications:

  • Boiler System Renovation & Boiler replacements
  • AHU upgrades & Replacement
  • Perimeter Induction Unit Revitalization & Replacement
  • Interior Floor Zoning Improvements & System Upgrades
  • Building Automation System Replacements & System Upgrades
  • 6th Floor IT Room Renovations & Expansion
  • Original Electrical Component Repair Replacement

This project required careful control of extent of scope as well as budget, as the entire building renovation effort required minimal interruption to the staff, general building functions, and operations. JMT worked hand-in-hand with the client developing alternative system analysis for various design solutions to establish the most efficient system performance solutions while also creating a design solution with minimum impact to the personnel and functional operations of this critical operational center for the state government affairs of MDSHA. JMT conducted existing conditions field surveys, cross referenced field data against existing documentation, and updated the documents electronically. These electronic files where then utilized as the basis for establishing the baseline energy efficiency performance for comparisons to the multiple alternative systems analyzed for system replacement. The old boiler systems were removed and replaced with high efficiency gas fired boilers at much smaller frame size due to the improved building envelope design from that of the original structure. HVAC controls were upgraded from pneumatic to direct digital control and HVAC pumping was revised to variable frequency drive with high efficiency motors improving water distribution and well as energy consumption. The air handling systems were also upgraded and provided with high efficiency fan motors. 

Care had to be taken with the redesign analysis for the perimeter HVAC systems to assure that staff comfort was maintained and staff operational interruptions were minimized. Multiple HVAC computer modeling scenarios were conducted on the perimeter load impacts to assure that the resultant design implementation could be conducted within the existing perimeter equipment housings, so as to not disturb the staff stations. The resulting design minimized cost impact as well as assured that the building renovation budget was held intact.
