Project Spotlight: 350 Park Avenue, New York, NY by Dan Chavez

January, 16, 2019 at 02:00

HEA was hired by Citadel LLC to provide commissioning services for 350 Park Avenue, a commercial high-rise building in New York, NY. HEA’s scope of work included all mechanical, electrical and fire protection systems including chilled water pumps, VRFs, CRAC units, VAVs, exhaust fans and electrical panels and all emergency power systems including automatic transfer switches, uninterrupted power systems, static transfer switches and the emergency generator. HEA also worked with installing contractors to develop start-up plans and provide guidelines for several pre-functional requirements including point to point testing, flushing & cleaning piping systems, testing adjust & balancing (TAB), pre-testing of sequence of operations and verification of base building provided systems.

Q/A with Dan Chavez, Senior Engineer

What was the biggest challenge faced during this project and how was HEA able to navigate through any problems faced due to this challenge?
There was a stringent construction schedule that took place over a 7-month span (December 2016 – June 2017) in order to bring in Citadel employees into the new space and start their daily business operations. HEA held regular commissioning meetings with the design team, owner, MEP trades and vendors in order to promote timely responses to major items that were of concern.

If HEA did not properly address the deficiencies found, how would this of negatively affected the building’s performance?
During the Pull the Plug Test, it was discovered that the BMS was not indicating correct demographic values for the generator and the STS’s (ex: the generator displayed a value of 1802 RPM but the BMS displayed a value of 901 RPM. Similarly, the STS load percentages displayed incorrectly at the BMS; STS-A & STS-B displayed 14% and 10% load respectively, but at the BMS indicated only 3% for both units. Obviously this indicated that the BMS vendor had to go back into their software to recalibrate their programming; otherwise the Citadel team would not be collecting accurate data at the BMS for those specific pieces of equipment.

Based off of client feedback, where do you feel we provided the most value to the project?
I feel that the client was most pleased with us really ensuring we captured all the proper documentation for the project’s final report. Throughout the project, Citadel always put emphasis on ensuring that all start-up and static reports (ATS test reports, static test reports, UPS/STS start-up documents, etc.) were captured as part of or final report. The final report now serves as an instrumental tool for the client whenever they want to go back and reference a field report or operator’s manual.

What do you think the success of this project shows about the qualities of HEA?
Given the aggressive construction schedule; HEA was able to adapt to making itself available under short notice for site visits. This attribute goes a long way in serving as an advocate for the client, in order to ensure they’re obtaining a fully functional and operable space.
