General

The architectural scope of this project is to provide for the removal of minimally used plumbing fixtures and identified dead legs of piping within plumbing system. After these fixtures are removed, the existing walls will need to be repaired and refinished.

After further investigation and design, it was found that removal of the unused plumbing fixtures would fascilitate the need for major renovation of the associated office spaces to improved the quality of patient care on the 3rd and 4th floors of building 228. Originally building 228 was designed as an inpatient mental health fascility where individual paitient rooms and bathrooms were a necessity. As the use of the bulding has changed to primarily outpatient care, many of the rooms were changed it to offices for doctor consultations and therapy. The required square footage for offices based on the VA

Design manual is 120 sqft. It as found that by decreasing the square footage of existing offices, it would allow for the addition of several right sized office to provide better patient care. This addition not only fascilitates improved patient care, but also mitigates the risk of legionella developing within unused fixtures within the building. The remote monitoring stations on the fourth floor will be placed in utility rooms that replace the existing unused toilet rooms, however, it is necessary to construct new utility closets to house the monitoring stations where it was not feasible to locate in renovated utility rooms.

These closets will be constructed of cold-formed steel studs and gypsum wall board. The closets will also have a three foot wide single door directly infront of monitoring equipment to minimize footprint and allow for required maintenance clearances. The closets will be located so as to have minimal impact on the daily operations of the hospital and staff, while minimizing the distance to plumbing risers that are being monitored.

General

The scope of this project is to develop a domestic water management plan to minimize the bacteria levels in the domestic water system at Building 228.

1. Locate and remove unused lengths of domestic hot and cold water pipe (dead legs) and infrequently used plumbing fixtures.

2. Install UV light water purification on the incoming cold water service. The UV light will disable the

DNA of pathogens present in the incoming domestic water, leaving them unable to reproduce.

3. Install a hot water monitoring system for Building 228 to monitor acidity, temperature, conductivity, pressure, and oxidant residual. Either an automated hot water flushing system will be utilized in conjunction with the monitoring system.

4. After three months of monitoring without secondary disinfection, Hines VA decides whether to incorporate secondary disinfection into its water treatment plan and if additional monitoring points are needed. Provide a permanent chlorine injection system in the basement mechanical room.

5. A portable chlorine based injection cart will be used for shock treatment of the system if legionella is detected.

5.0 MECHANICAL SYSTEMS

A. Existing HVAC Systems:

1. A centralized chilled water system provides space cooling for the entire Building 228, which includes cooling coils of air handler units and radiant ceiling panels. Two 250-Ton chillers are located in the basement of Building 228. Three primary chilled water pumps, two secondary chilled water pumps, and three condensate water pumps are located in the basement of Building 228 as well. Cooling towers are located on the ground. Two pumps for chilled water radiant panels are located in the penthouse mechanical room.

Existing chillers are running almost full load in hot summer days.

2. High pressure steam from the campus heating plant is the heating source for this building. 180 O

F space heating hot water is generated from steam to hot water converters. Two converters and two hot water heating pumps are located in basement mechanical room. Another two converters and two hot water heating pumps for radiant heating panels are located in penthouse mechanical room. Each heating coil of AHU has a local circulating pump.

3. There are four Air Handler Units for this Building. Each one has hot water heating coil(s), chilled water cooling coil(s), and low pressure steam humidifier.

F supply air is distributed to each floor.

In each floor constant volume boxes with reheat coils provide tempered air to each area. 4-pipe radiant ceiling panels provide supplement cooling and cooling for each patient room. Heating only ceiling panels are for some common areas such as corridors.

6. Currently HVAC systems in Building 228 are controlled pneumatically except the new chillers.

7. The existing patient rooms are currently being exhausted via their associated bathroom rooms by transferring the air under the door.

8. The existing building automation system is by American Auto-Matrix.

B. New HVAC Systems:

1. Existing AHU-4 will be reused for 3 rd and 4 th floors. Existing supply and return ducts in the renovated areas will be modified and enlarged to accommodate new or existing air flow rates. Existing constant volume boxes with hot water re-heat coils will be replaced with new units based on the new floor layout and zones. New 4-pipe Fan Coil Units will be used for the area that require high volume air flow or have extra internal loads, such as large conference rooms, waiting areas, and break rooms, etc. Existing 4-pipe radiant ceiling panels will be reused and rearranged, along with associated piping, for new floor layout.

2. HVAC system will be zoned to meet the client requirement. Typically two to four offices with the similar schedule and exterior envelope load will be zoned together and controlled via a local wall mounted T-stat.

3. In renovated areas all existing pneumatic devices such as control valves, thermostats and terminal units will be upgraded to electronic control.

4. Existing rest room exhaust systems will be modified if necessary per new floor layout.

5. Because some existing restrooms have been converted to storage rooms the doors have been relocated to open into the corridors instead of the patient room. Therefore new air transfer grilles will be provided on the storage room wall to transfer the exhaust air from the office/exam room space to the existing exhaust located in the storage room. In order to maintain patient privacy the grilles on the office side of the wall will be offset from the grille on the storage room side of the wall by locating one grille near the floor and one grille near the ceiling. Doing this makes it so there is no direct line of sight or sound through the grilles so if someone is in the storage room they will not be able to hear any conversations in the exam room.

6. All new equipment will operate off of a new control system which will be installed and run in conjunction with the existing Building Automation System.

II. Plumbing Systems Descriptions

1. Identified unused lengths of hot and cold water distribution piping (dead legs) and infrequently used plumbing fixtures will be removed to reduce the water age and the potential for bacterial growth in low flow sections of pipe.

2. A new UV light water purification system will be installed on the incoming domestic cold water service.. The UV light system will be installed with a UV lamp tube and a monitoring system that shows lamp status, lamp run time, unit power on time, high water temperature shut off, cabinet high temperature, alarm history, lamp remote on/off, lamp out alert and UV intensity and temperature.

3. Six hot water monitors will be installed throughout the hot water distribution system to monitor temperature, pressure, and oxidant residual. The first monitor will be located in the lower level mechanical room downstream of the chemical injection point, downstream of the heat exchanger. The second monitor will be located in the lower level mechanical room on the hot water return, upstream of the heat exchanger, upstream of the hot water circulation pumps. The last four monitors will be located in service closets on the fifth floor. The four remaining monitors will be installed at distal points on risers throughout the building. The Potable Water Analytics

(PWA) will be used to send the monitored data to a cloud based software platform. The hot water monitors will control either a hot water system flushing solenoid valve or the chemical injection system. Each monitor will require a floor drain and piping to tie into existing building hot water loop.

4. The chlorine injection point will be installed in the lower level mechanical room on the hot water supply, downstream of the heat exchanger.

5. Per the VA Standard 1061 the cold water incoming water service will be monitored for temperature, pressure, acidity, conductivity and oxidant residual. The cold water incoming service will be monitored only; the collected data will not control any elements of the system.
