Project Description

PROJECT DESCRIPTION

1333 H Street is a two tower 12-story office buildings – constructed in 1912 and 1982, respectively – located on the corner of 14th and H Street. During the time of the renovations, the building was 95% leased with some of the major tenants including The Institute of International Finance and Center for American Progress.

Mallick Mechanical Contractors was responsible for upgrading the central plant equipment, adding DOAS terminal units and route piping on each occupied floor, installing a “blending station” for higher temperature chilled water on every floor and upgrading the lobby and core bathrooms.

STRATEGIES

In order to minimize tenant impact, Mallick Mechanical Contractors had to install a new supplementary system and keep the existing constant volume air handling units running – all in the span of a weekend.

The Central Plant renovation consisted of replacing both chillers – with one Multistack Modular Chiller and one Trane Centrifugal Chiller – and had to be decommissioned and installed in two phases due to the building maintaining a cooling load.

However – due to a tight deadline – Mallick Mechanical Contractors did not have the luxury of phasing the equipment with the Cooling Tower. In the tight windowed weekend – Friday at the close of business to Monday morning before occupancy — the Cooling Tower and associated pumps were demolished, installed and operational.

With this in mind, Mallick Mechanical’s project manager and foreman developed an hour-by-hour spreadsheet to better understand how much labor and time is required for each task. This detailed operating system was shared with the appropriate parties, ensuring that everyone was on the same page from the start of the tight deadline.

CHALLENGES

After the system’s assembly and demo were completed, Mallick Mechanical Contractors worked closely with Davis Construction and other trades to coordinate the installation of the new 4-pipe system and outside air duct runouts for each floor with existing office space.

The Central Plant renovation consisted of decommissioned both chillers – with one Multistack Modular Chiller and one Trane Centrifugal Chiller – and had to be installed in two phases due to the building maintaining a cooling load.

However – due to a tight deadline – Mallick Mechanical Contractors did not have the luxury of phasing the equipment with the Cooling Tower. In the tight windowed weekend, the Cooling Tower – along with associated pumps – were demolished, installed and operational for Monday morning office occupants.

The building’s location made it difficult for Mallick Mechanical Contractors and their coworkers with no lay down area. However — with no area for assembly or storage on site — Mallick Mechanical Contractors’ prefabrication shop was fundamental for the project’s success.

Due to our team’s ability to plan ahead, communicate with one another and others on the project, Mallick Mechanical Contractors was able to effectively preassemble chilled water pump headers, condenser water pump headers, cooling tower yard’s piping, DOAS box valve packs, boiler headers, hot water pump headers and deliver it in a timely manner that sustained the project’s delicate schedule.

TESTIMONIAL

“The Mallick team was an absolute pleasure to work with throughout the duration of the 1333 H Street project. The team went above and beyond expectations and were very easy to work with as well as performed well with our other subcontractors on the project.

 The field staff did a phenomenal job working with DAVIS and our subcontractors to complete their work on schedule. Mallick’s field and office staff consistently met DAVIS’ expectations and worked to provide the best quality product for the Owner. I would strongly recommend this team for other DAVIS projects.”
