Long Beach Medical Arts Pavilion - Effective Tuesday, September 21, 2021

The accumulation of water on the Long Beach Medical Arts Pavilion site is ground water which is slated to be safely removed so construction can resume. We have secured approval to commence the dewatering effort from all governmental oversight agencies, including the New York State Department of Environmental Conservation, and we will begin mobilization later this week. You should be prepared to see dewatering equipment like Weir tanks, pumps and hoses.
EW Howell, our general contractor, will work directly with the Keller, a leading ground water control company, who will be mobilizing at the site later this week. The mobilization effort will take approximately 10 days. The full dewatering operation is anticipated to run 8 hours a day, 5 days a week. Pumped water will be filtered and treated and then safely redirected into Reynolds Channel. The water being pumped into the channel has met all environmental standards for this type of operation. We will be pumping the ground water around the clock to a level down to a point where concrete can be formed and poured. We will not be using a diesel generator for this operation. Instead, we secured a quieter and more environmentally friendly publicly metered electric service from PSE&G. The remaining pile caps, footings and foundation activities will recommence during this dewatering process.

Emergency Department Walk Up Entrance - Effective Tuesday, May 10, 2021

Please be aware that effective Tuesday, May 11 at 5AM our Emergency Department walk up entrance will be located at the hospital’s Washington Ave entrance. Emergency walk up patients will have the option of valet parking by proceeding to the valet booth or self-park their vehicle upon entering the parking lot. Outpatients entering at this location will be required to self-park their vehicle and enter through the designated entrance.

J Wing Addition - Effective Friday, April 23, 2021

Ambulance access to Mount Sinai South Nassau’s Emergency Department bays will no longer be possible from Oceanside Road; all ambulances must enter the ED bays via the Nassau Parkway entrance.

This change is necessary to accommodate construction on the hospital’s new J Wing, which will nearly double the capacity of the hospital’s current Emergency Department.

This traffic change affects ambulance traffic only! Walk-in patients to the Emergency Department will continue to enter Emergency Department lot from Oceanside Road.

Central Utility Plant - April 5, 2021 Through Friday April 23, 2021

As part of the ongoing Central Utility Plant (CUP) Project, the parking lot on the west side of the hospital (north of the loading docks) will be closed. Traffic flow and access to the loading docks remains unaffected. All persons previously parking in this parking lot can access the hospital from the main entrance where valet parking is available.

Oswald Court Closure - January 18, 2021 through May 17, 2021

As part of the ongoing Central Utility Plant (CUP) Project, Oswald Court will need to be closed between Washington Avenue and One Healthy Way to run underground utilities across Oswald Court. This work will start on Monday, January 18, 2021 and is estimated to be completed by the week of May 17, 2021.

This work is being done over multiple phases in order to ensure that:

  • Entrance and exit from Hospital's main drive remains unaffected.
  • At least one side of the Oswald Court sidewalk will be accessible for pedestrians.

Signage will be installed in the area to aid directing vehicular and pedestrian traffic.

Central Utility Plant

In January, 2020, Mount Sinai South Nassau began construction of a new, energy-efficient $90 million Central Utility Plant. The new plant will upgrade the hospital’s electrical, heating, ventilation and cooling systems and fortify the hospital’s infrastructure against potential future storms. The plant also will help provide power for a planned four-story addition with new operating suites, an expanded emergency department and 40 new critical care beds, all of which is part of a more than $400 million long-term strategic growth initiative designed to improve service for patients across the South Shore of Long Island. Hundreds of building trade jobs will be created as these projects are constructed.
