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.
