Ft. Detrick Maryland Project SheetJun 21, 2013
|Location:||Ft. Detrick, Maryland|
|Project Duration:||October 2011 – June 2012|
Building 1425 located at Ft. Detrick, MD is the only U.S. Department of Defense Laboratory equipped to study highly hazardous viruses at Biosafety Level 4. The “Dan Corvier” Building is home to the U.S. Army Medical Research Institute of Infectious Diseases (USAMRID) and has played a leading role in research for biological agent medical defense. The building is currently undergoing upgrades of the existing HVAC systems including Air Handling Units (AHUs) and Exhaust Fans (EFs), under the construction management of J&J Worldwide Services.
sys-tek was contacted by J&J for support and commissioning services when complications with freeze-stat nuisance trips and standby exhaust fan difficulties were encountered. An initial site survey was conducted October 12-14, 2011 and commissioning was performed during the week of November 13, 2011. This included a thorough inspection and functional performance review of the AHUs AC-5 and AC-10 as well as their associated dedicated and standby exhaust fans. AC-5 and AC-10 are 100% fresh air units for the service of BSL-4 Laboratories.
Field Installation Verification:
Physical review of the installation of each piece of related equipment. This review was targeted to ensure maintainability and proper installaion.
Functional performance testing of each piece of equipment included
Proper reaction to changes of building automation set points, including air flow, static pressure, cooling/heating valve modulation and exhaust fan activation.
Various tests on the variable volume air handling including, unit startup and supply/exhaust fan checkout, pre-hear performance, high static tips, low-limit safeties, chilled water coil performance, heat recovery coil performance, humidification and dehumidification control checks and all associates alarms.
Review of the Building Automation System (BAS) and manipulation to verify proper control and graphical representation.
