Valley Health System, The New Valley Hospital

The New Valley Hospital, exterior

Overview

GBA provided design review and commissioned all MEP/FP systems, including typical hospital HVAC and controls systems, electrical and emergency power, life safety, security/PA, fire alarm and suppression, nurse call, and medical gases at a major new replacement hospital on a 40-acre campus comprising about 910,000 square feet and 300 beds, plus a five-story parking garage and a new central plant. The firm also supervised the work of a building enclosures commissioning subconsultant.

Design Review and Commissioning

The New Valley Hospital is a full-service acute care facility comprising three interconnected bed tower wings of five stories each, constructed over a three-level podium that connects all wings at the base. The hospital includes 242 medical/surgical beds, 56 ICU/CCU beds, an emergency department with 50 treatment areas, a 20-bed clinical decision unit, NICU, LDR/C-section rooms, clinical labs, a USP 797/800 pharmacy, 24 operating rooms, two EP procedure rooms, four catheterization labs, and two endoscopic procedure rooms. Diagnostic imaging facilities feature two MRIs, three general radiology rooms, five CTs, and two ultrasound rooms.

Sustainable features include green roofs, energy recovery wheels, water-side economizer cooling, OR air change setbacks, and advanced lighting controls.

One key aspect of construction-phase commissioning was developing pre-functional checklists. GBA prepared 7,253 checklists. These checklist items were filled in by the installing contractors to confirm that installed systems and equipment were ready for functional performance testing.

GBA identified 466 design-phase items and 2,720 construction-phase items through review and testing. Major issues found and corrected via commissioning included:
A defective reheat pump that was repaired.

  • OR occupancy sensor mis-wiring, resulting in the room reading as “occupied” even when it was vacant and defeating the programmed air change setback strategy.
    Incorrectly programmed fuel oil system transfer pumps.
  • A clogged steam pressure transducer, causing erratic and improper steam boiler cycling.
  • A faulty computer room air conditioning unit that was causing overheating of the IT space.
  • The electrical short circuit coordination study did not match installed devices; uncorrected, this could have resulted in nuisance tripping.
  • Issues with a heat recovery chiller module, patient isolation room supply diffusers, incorrectly installed chilled water system valves, wrongly installed autopsy exhaust ductwork, and a variety of other mechanical system problems.
