New York University, StudentLink Center

Commissioning

Commissioning - New York, NY

Overview

G/BA commissioned MEP systems for facility conversion to create a 65,000-square-foot student service center. The university’s registrar, financial aid, bursar,and international student services offices are located in the facility, now known as StudentLink Center.

Features

The project encompassed a gut renovation and extension of a four-story New York City landmarked masonry building. G/BA’s involvement spanned the design phase through the turnover phase.

Mechanical, electrical, and plumbing systems were commissioned, including: 

  • Chilled water systems: chillers, pumps, and air-handling units.
  • Boiler systems: boilers, pumps, and chemical treatment systems.
  • Condenser water systems: cooling towers, pumps and chemical treatment systems.
  • Building automation and daylighting control systems.
  • Variable air volume boxes with reheat coils and perimeter radiation units.
  • IT room air-cooled condensing units. 

G/BA conducted design reviews of the building envelope and MEP system at the 50% and 100% design documents stages and at the 100% construction documents stage. Design and construction issues were tracked via G/BA’s online commissioning tool, CxAlloy. The tool allows the project team to review and address the issues and requests identified by G/BA, and provides ownership for tracking the commissioning process.

G/BA witnessed required project tests such as ductwork pressure, hydrostatic pressure, and electrical Megger (insultation resistance).

Items identified and corrected as a result of construction-phase commissioning included:

  • Improper calibration of outside airflow stations, causing air-handling units to underperform.
  • Missing minimum flow bypass control valve in the heating system. The valve is required for proper operation.
  • Improper space temperature maintenance due to reverse-wired reheat coils on variable air volume boxes.
  • Partially closed fire smoke damper, decreasing air-handling unit capacity and increasing intrusive space noise.
