Project Description

Challenges were not in short order when it came to the renovation of an occupied Office Building in the heart of DC.

  • Routing of piping through existing ceiling space in occupied offices? Check.
  • Installation of a new supplementary system while keeping the old one up and running? Check.
  • Replacing the Central Plant equipment without having any down time? Check.
  • Having to plan and stage accordingly because there is no lay down area? Check.

The Mallick team met all of these challenges head on and succeeded in being an integral part of the success of this project.
1333 H street is an existing office building where the existing spaces are fed by a constant volume air handling unit. The scope of the renovation included upgrading the Central Plant equipment, add DOAS Terminal Units on each floor, installing a “blending station” for higher temperature Chilled Water per floor, upgrading the Lobby, and upgrading the Core Bathrooms. The Mallick team worked closely with Davis Construction and the other trades to coordinate the installation of the new 4 pipe system and Outside Air Duct runouts on each floor within existing office space. The Central Plant replacement consisted of replacing both Chillers with one Multistack Modular Chiller and one Trane Centrifugal Chiller. Due to an Office Building always have some kind of cooling load the Chillers were decommissioned and installed in two phases. The luxury of phasing the equipment did not exist with the Cooling Tower – in one weekend the Cooling Tower (and associated pumps) were demolished, installed, and operational for Monday morning occupants. The Boilers were also replaced and a new DOAS unit was installed (in very tight quarters).

The Mallick team continued to press forward – helping to solve issues related to the logistical complexities of an occupied renovation. Through intense planning and determined execution the Project was completed to the satisfaction of the Davis Construction team and the Owner.
