  • Duration: Aug 2017 - Feb 2019

  • Location: Woodlawn, MD

  • Owner: Social Security Administration

  • Contract Value: $1,067,872

Prime contractor on this Social Security Administration project to upgrade the fire alarm, sprinkler system, and mechanical equipment at the Robert M Ball building.

The project involved the replacement of (30) fire alarm beam detectors, (30) fire alarm beam reflectors, (6) fire alarm smoke detectors, (44) fire alarm duct detectors, and (40) fire alarm test switches in the large box atrium and linear atrium areas of work spread across four floors of the building.

The project also entailed installing mechanical ductwork extensions and fire alarm duct detectors in the air returns of twenty-two (22) server rooms throughout the building. Upon completion of the mechanical ductwork extensions and fire alarm duct detectors in the sever rooms, the remaining defective duct detectors installed inside the roof top AHUs were demolished. 

Administrative, engineering, negative air, personal protective equipment, adhesive mats, temporary protective covers, temporary plastic barriers, air filters, tools, and additional dust control measures were implemented prior to the start of work onsite to control dust pollution levels and maintain occupant health and comfort during and after construction.

During construction, we identified sixty-six (66) potential scope conflicts between the new drywall bulkheads requested and various existing conditions in the areas of work, including the Server Room. The impacts of these existing conditions required 50% of the new drywall bulkhead finishes to be revised.

We identified over 100 remaining dampers were not operational and worked with the Government and Design Team to replace these actuators and retest both systems together.
