Project Spotlight: Manhattan Supreme Court, Energy Conservation Measures (ECM) Implementation 

March, 12, 2019 at 32:00

The New York City Department of Design and Construction (NYCDDC) contracted HEA to provide existing building commissioning services for the Manhattan Supreme Court ECM Implementation project in New York, NY. Services being provided include the commissioning of the following systems: electrical, demand control ventilation, chillers, condenser water pumps, cooling tower, and HVAC sensors and controls.

Client: New York City Department of Design and Construction (NYCDDC)  

SF: 322,000 sf

Location: New York, NY

Q/A with JT Himelrick, Field Engineer

When first contracted for this project, what did the client express as the main goal/most pressing need for our services to accomplish?

Since my involvement in this project, the most pressing need for HEA has been in the air handling unit controls upgrade. Since each unit has numerous sensors and equipment that are being upgraded, keeping track of the issues that arose and their solutions has proven to be a challenge and the service most needed from HEA.

Project Spotlight: Hudson Valley Hospital MRI Replacement 

February, 26, 2019 at 04:00

Horizon Engineering Associates, LLP (HEA) was contracted by Group PMX, LLC to provide design phase commissioning services for the Hudson Valley Hospital MRI Replacement project in Cortlandt Manor, New York. HEA’s scope of work includes commissioning of the mechanical, electrical and plumbing systems to ensure all that all systems and equipment are installed and operating according to design intent.

Client: Group PMX, LLC  

Location: Cortlandt Manor, NY

Q/A with Anthony Grgas, Senior Project Engineer

Have you ever commissioned a project involving an MRI replacement before? If so, what are the challenges with these types of projects that you have faced before and if not, what challenges are you expecting to possibly come across?

I have commissioned an MRI project before and there are many interesting aspects and challenges about them:

  • All building materials within the MRI room must be ferromagnetic (for example-only aluminum lighting fixtures and stainless steel duct)
  • The entire MRI is encased in a shell constructed out of copper sheets/plates to act as a faraday cage and block out radio noise that could interfere with the imaging process
  • The supermagnet within an MRI magnet is usually filled with helium at cryogenic temperatures, that must be provided with a cryogenic venting system as an instantaneous means of venting (in case anything goes wrong with the magnet or magnet cooling system)
  • The cooling is usually provided by a dedicated process chiller, with an emergency domestic water switchover for emergency cooling in case of chiller (or chilled water pump) failure
  • All mechanical equipment must be on critical emergency power circuits

Skidmore, Owings & Merrill, LLP hired HEA to provide building envelope consulting services for the Miami Central Station (a part of the 235-mile network of rail lines that will connect South Florida to Central Florida). This massive elevated station will sit on various blocks of parking lots between the Metrorail tracks and NW 1st Avenue, connecting to the Government Center station. This facility will serve as a place where trains, buses and shuttles will all meet under one gigantic roof. HEA is providing ongoing building enclosure consulting and peer review services for the exterior enclosure systems, which includes duties such as: Review of curtain wall, metal panels and extruded aluminum infill screen; review of soffit system design and shop drawings; review of any glazing impact testing; review of visual mock-up drawings and specimens including standalone glass sample reviews, factory inspections; site visits and attendance at project meetings as required in New York City and Florida.

Project Spotlight: George Washington Bridge Bus Station, New York, NY by Frank DiSalvo 

January, 30, 2019 at 18:00

The George Washington Bridge Bus Station (GWBBS) is located in Upper Manhattan and averages more than 20,000 customers per day. This project was an adaptive re-use of the existing GWBBS facility and has a life expectancy of 50 years. The project included consolidated bus operations, direct vertical transportation from the street and subway levels and 120,000 sf of retail space. HEA’s scope of work included all mechanical, electrical and plumbing systems; all of which met the necessary requirements to satisfy the Port Authority of New York and New Jersey Sustainable Design Guidelines for Energy Environmental Qualities Credits (EEQ)-2 Building Systems Commissioning.

Q/A with Frank DiSalvo, Senior Project Engineer

When first contracted for this project, what did the client express as the main goal / most pressing need for our services to accomplish?
HEA’s initial commissioning discussions with STV, Inc. began with a minimal outline of coverage, beginning only with the interests of covering the basic major systems of this bus station overhaul back in the early period of March 2010. The progress and relationship began slowly with a need for improvement on the work progress and coordination of system testing.

What was the biggest challenge faced during this project and how was HEA able to navigate through any problems faced due to this challenge?
The project was experiencing unforeseen delays and sluggish progress partway into construction, so one of the many challenges faced was managing onsite commissioning with uncoordinated contractors and project managers. With high scheduling and budget concerns, HEA teamed up with a new project director (DV) and began conducting regular progress and commissioning meetings to get all contractors and subs onboard towards a team goal.

Spot the Deficiency! January 2019 

January, 03, 2019 at 18:00

Q: What needs to be fixed?

A: This is a deficiency because the duct is going to run into the pipe. Either the pipe or the duct has to be moved. If this was not caught by the commissioning process, the project would not be able to continue; the ductwork could not be finished until the pipe moved.

Did you get it right? Let us know!

Thank you to Phil McCrory, QCxP, Field Engineer, for capturing this.

Q: What needs to be fixed?

A: Questionable temporary shoring used to support an unstable shelf angle at a brick veneer parapet.

Did you get it right? Let us know!

Thank you to Eric Turcotte, Field Engineer, for catching this.

Featured Deficiency September 2018

Featured deficiency: Control Panel

A wall was built around the control panel (on the left) where the conduits go in. Will be unable to access the controls or do any service on this unit.

Featured Deficiency! July 2018 

July, 31, 2018 at 55:00

Featured deficiency: Dirty Pipes

Having dirty drain pipes would lead to clogging which is the sole purpose of having drain pipes in the first place! Timely flushing and cleaning water treatment would prevent this. In this case, the facility was having issues because of the age of the building and that it was not properly maintained. We were able to snap a picture of the samples they took after pipes were cut out.

Behind the Scenes: Support Columns 

June, 18, 2018 at 39:00

Photo is in the basement of a prominent museum in Philadelphia, PA. As part of the Core Phase project, the museum is performing a lot of excavating to make way for increased usable space for galleries, classrooms and support areas. In some areas, they have found that the footings below some of the 90 year old support columns need to be deeper and/or repaired. The shoring is in place on either side of the support column so that they can install new footings. The scale of this is pretty impressive when you consider the bottle of water on the right hand side of the photo.
