Beckley Hospital Endoscopy Suite; West Virginia

The project consisted of the renovation of approximately 1280 sq. ft. of space on the 5th floor to create a new Endoscopy Suite.  The design incorporated applicable requirements of VA Directive 7176 and VA Supply, Processing, and Distribution (SPD) including maintaining proper temperature and humidity conditions, proper air flow rates, and proper relative pressurization. 

A new HVAC system was provided for the renovated space using existing steam and chilled water piping. The new unit included energy recovery conforming with energy reduction mandates.  The new air handling unit is located either on the roof or in a new Mechanical Room adjacent to the project.  Air is provided to spaces at the rate of 10 air changes per hour in clean areas and 6 air changes per hour in decontamination area. A new steam-to-hot-water heat exchanger was required.  Steam and chilled water utilities were extended to the new air handler location as part of the design.

Plumbing systems were modified as required to suit locations of new sinks and floor drains.  Included were interior plumbing sanitary drainage system and water piping from existing main piping systems.

Electrical systems were modified to suit new room layouts and functions which included lighting, power, exit lights, egress lights, fire alarm, data/communications wiring, and relocation of speakers as required to suit new ceiling layout. Emergency power circuits were added as required.

ISSUES DISCOVERED: 

  • Inadequate emergency distribution system for hospital
  • Aging automatic transfer switches 
  • Aging emergency distribution equipment

CREATIVE SOLUTIONS:

  • Tec completed and documented surveys and visual inspections of all HVAC equipment

CLIENT SATISFACTION:

  • Tec completed the Central Plant emergency electrical distribution upgrades and emergency generator upgrades resulting from the HVAC evaluation
  • XX projects completed for Lakewood Hospital


Beckley Hospital MRI Addition; West Virginia

This project consisted of a new two-story addition to the north side of the existing Veterans Administration hospital. The first floor of the addition was approximately 2,280 sq. ft. The first floor space was used to expand the existing emergency room, and the project included renovation of approximately 4,300 sq. ft. of existing emergency room space and 1,600 sq. ft. of waiting room space to achieve a comprehensive emergency room layout.

The second floor of the addition (2,280 sq. ft.) connects to the radiology suite and contains a new MRI unit, all related controls, and preparation and reception areas

The electrical work included new lighting, receptacles (normal and emergency), exit lights, egress lights, fire alarm (extension of existing system), data/communications wiring back to the Intermediate Distribution Frame, and public address speakers (extension of existing system) for the new addition. Existing electrical systems were modified to suit new room layouts and functions in renovated areas.

A new HVAC system was provided for the addition using existing steam and chilled water piping. A new unit included energy recovery to conform to energy reduction mandates. Two new air handling units were included in the project; one for the MRI area and one for the ER area.  HVAC design also included a new chiller dedicated to the MRI, emergency exhaust of the Scanning Room and extension of the cryogenic vent from the magnet to outside the building. 

Plumbing work included new sanitary drains, sanitary vents, domestic hot and cold water piping, medical gas piping, and plumbing fixtures required for the new addition.  New piping systems were connected to existing systems. Existing sanitary drain, sanitary vent, domestic water, and medical gas systems were modified to suit the layout of the renovated Emergency Room spaces. Fire Protection design included extending existing wet-pipe sprinkler systems to serve the new addition.

Specific design requirements for systems were coordinated with the installation requirements of the MRI equipment being furnished.  Construction of the project was phased to minimize downtime of the Emergency Room. 

PROJECT CHALLENGES: 

  • Discovered during construction that the VA had a separate project that was using the same electrical source as the MRI addition project. 

CREATIVE SOLUTION(S):

  • Monks’ engineers developed a solution to shift electrical loads around to be able to use available breakers which resulted in minimal changes to the project.

CLIENT SATISFACTION:

  • Monks Engineers, LLC has completed more than 5 projects at Beckley Hospital for the Veterans Administration

Beckley Hospital Negative Air Pressure Building 1; West Virginia

Several decades of renovations—-including additions—that ignored the overall building pressure balance in a seven-story, 290,000 sq. ft. hospital (Building One), resulted in a negative air pressure issue for this Veterans Administration facility. Monks engineers designed a HVAC solution to provide overall positive pressure with respect to the outside.

It was necessary to verify current performance of all supply and exhaust units, and to determine where additional make-up air should be delivered to the building. Monks’ scope of work included gathering information about the existing air handling units and duct systems from a flow, pressure, RPM, and horsepower perspective. The design included appropriate controls to maintain positive building pressurization under all operating conditions. All new controls were incorporated into the existing DDC system. Five new make-up air handlers were provided to supplement the existing units and to ensure proper performance.

PROJECT CHALLENGES: 

  • A site investigation determined that the kitchen needed an additional 6,000 CFM of make-up air.  Since the kitchen’s existing ceiling space was full, there was no possibility of delivering the make-up air in a conventional manner.

CREATIVE SOLUTION(S):

  • A wall of make-up air was designed in a new chase to deliver the air slow enough to diffuse draft concerns.

CLIENT SATISFACTION:

  • After construction was complete, the client reported that the symptoms of the building’s negative pressure problems—leaves constantly being sucked in the building entrance, drafty conditions, etc.—had been eliminated.

Beckley Hospital Standpipe Replacement; West Virginia

Prior to this replacement, the hospital had five fire protection standpipes.  Three of these standpipes were part of a combined system (feeding sprinkler risers), and went the full height of the building.  New exterior mains from the remote fire pump to two of the standpipes were installed in the 1990’s.  The other three standpipes were fed underground via original building piping installed in 1948.

The project included relocation of the three combined system standpipes into existing stairwells and relocating the sprinkler flow and tamper switches into those same stairwells.  The other two standpipes were replaced in their existing locations.

The project included the replacement of the existing 75 HP fire pump in the remote pump house.  The new pump was designed to maintain 100 psi residual pressure at the topmost fire department valve per NFPA 20, Article 7.8.  

Also as part of the project, we recommended and designed the installation of a domestic water booster pump system to regulate domestic water system pressure.  The existing system utilized the jockey pump to regulate domestic water pressure.


Nashville Hospital Ward Upgrade 2G; Nashville, Tennessee

This project renovated approximately 11,500 NSF on an existing inpatient ward located on the 2nd floor of the hospital. 

Ward 2G renovation reconfigured the patient rooms to provide private and semi-private patient rooms with private handicap accessible toilet and shower facilities on the east side of the ward. The general layout of the renovated Ward 2G followed the proven design scheme of the completed surgical nursing unit on Ward 3 North, project 626-079, Ward Upgrade Phase 2 for Patient Privacy (activated in 2000) and Ward Upgrade Phase 3, 2 North (activated in 2006).  

The project was phased to maintain utility service to the medical center and to maintain adjacent operations during construction.  The design complied with the International Building Code, NFPA, and Department of Veterans Affairs standards.
