ADEM Coastal Office

and Lab

Alabama Department of Environmental Management (ADEM) has two locations in Mobile. The Mobile Coastal Field Office and the Mobile Central Field Office (Lab). One of these locations is a rented facility and the other is no longer suitable for the needs of the users.

• • Location:  Mobile, AL
  • Project Size:  15,000 SF
  • Cost:  $11,000,000
  • Facility Type: Government
  • Owner: Alabama Dept. of Environmental Management
  • Services:  Electrical and Mechanical/Plumbing and Fire Protection  Engineer

This project combined the function of two locations into one building that was owned by ADEM and tailored to meet their current and future needs. This project also provided significant enhancements in energy efficiency compared to the agency’s current two locations.  Dell Consulting provided mechanical, plumbing, electrical, and fire protection design and construction administration services for the project.

Mechanical systems include a chiller plant with two 110-ton air-cooled chillers (one fully redundant) located on grade in an outdoor equipment yard. Each chiller includes multiple compressors configured with independent refrigeration circuits to optimize system redundancy.  Chilled water (CHW) is distributed to the outdoor chiller plant and indoor cooling coils at air handling units (AHUs) and fan coil units (FCUs) by redundant pumps (lead / standby) in a variable-primary flow configuration.

Heating hot water (HW) is generated by two 725 MBH gas-fired boilers (one fully redundant).  Boilers are high-efficiency, condensing type to maximize energy efficiency and minimize equipment footprint.  HW is distributed to the boilers and heating coils at FCUs and variable air volume (VAV) terminal units by redundant pumps (lead / standby) in a variable-primary flow configuration.
