RENOVATION OF A & B – WINGS, BUILDING 6

STATEMENT OF WORK

COLMERY-O’NEIL VA MEDICAL CENTER, TOPEKA, KANSAS

Project 589A5-19-116 December 2019

1. SCOPE:

The Project consists of a major renovation project of Building 6 A & B Wings on the Colmery-O’Neil VA campus in Topeka, KS. The scope includes the remodel of the A & B Wings of Building 6 CLC, approximately 21,500 square feet. The work is to include a complete interior demolition of Wing B of approximately 11,404 square feet as required for new geriatric psychiatric resident rooms and resident/clinical support spaces. A complete demolition of Wing A of approximately 10,120 square feet will be required for a new Geri-PACT clinic and Building 6 offices and support spaces. A summary overview of the project objectives through new renovation includes:

Kitchen, Resident Laundry, Recreational Therapy and associated CLC unit support spaces specific to Wing B Geriatric-Psychiatric services;

F. Improved insulation and HVAC systems that meet the VA’s energy requirements for new construction;

G. A design and layout that supports patient privacy and meets the Safe Patient Handling requirements;

H. A domestic water system that minimizes the risk of Legionella to the greatest extent possible;

of CLC Residents;

K. Design the facility to include discrete security and safety features for the patients and staff, paying particular attention to Geriatric-Psychiatric resident requirements;

L. Implement walls and doors with high sound transmission coefficient ratings, and other architectural and engineering controls that contribute to resident & staff comfort.

All areas will be designed under the latest VA design guidelines listed:

The contractor will be responsible for meeting all contract specifications for the VAMC. The project shall include concrete, electrical, plumbing, steel framing, lighting, telecommunications and finishes work. The renovated wing will consist of 13 resident rooms including 12 standard resident rooms, and 1 bariatric resident room and shall be installed in accordance with all applicable standards available at time of installation to include published commercial specifications as well as standards and preferences expressed in this document. All installation details shall be fully coordinated with VA CO and on-site Contracting Officer’s Representative (COR). Period of Performance for all work 270 days

2. STATEMENT OF WORK:

2.1 SHOP/ DRAWINGS SHALL PROVIDE:

2.1.1 2D as-builts shall be provided to show all work that is installed in this specification.

2.1.2 The contractor shall provide complete drawings as stated in the specification.

2.2 DEMOLITION:

2.2.1 The contractor shall provide all materials and labor to perform interior demolition of the walls and associated finishes. Demolition in the basement will include, but is not limited to the following: chipping of concrete toping of the concrete pan joist floor, removal of perimeter brick and block wall, removal of flooring materials, removal of walls, including furring, removal of doors and frames, removal of ceilings, removal of lighting, removal of ductwork, removal of a window, removal of wiring and controls and miscellaneous associated items.

2.3 ELECTRICAL:

2.3.1 Recommended System Modifications/Upgrades:

GENERAL

The electrical portion of this project will consist of complete phased replacement of all Division 26 electrical systems, downstream of the existing main electrical service and main emergency distribution panel, for both A Wing and B Wing of Building 6. Because of existing asbestos and lead contaminants, A and B Wings will be fully demolished internally and remodeled to meet the new space programming requirements.

2.3.5 SITE POWER DISTRIBUTION SYSTEMS

Building 6 is currently provided electrical service by existing transformer 6-T1-A; this transformer is pad mounted, 500KVA, and transitions primary 12,470V campus power down to secondary 208Y/120V building power. The building side of the transformer is equipped with a 1600A circuit breaker which provides protection for the main service feeders supplying the Main Switch Board located in the basement main electrical room of Building 6. The existing transformer, secondary circuit breaker, main building feeders, and main switch board are all to remain.

2.3.6 SITE & BUILDING MOUNTED LIGHTING SYSTEMS

A. Site lighting and controls are not included in this scope of work.

B. Building mounted lighting and controls will be modified as related to the area of work outlined by the scope of work. Emergency egress lighting and controls for A and B Wing exterior exit doors will be provided as new. Any other building mounted lighting and controls will remain; new branch circuits will be provided if the remaining lights/controls are currently fed from a panelboard designated for replacement.

2.3.7 ELECTRICAL SERVICE AND GENERATOR UPGRADE

The existing building loads have been reviewed for the proposed modifications in A and B Wings, along with the current renovation project in C Wing and the existing loading in D Wing. At this time, we are recommending an electrical service upgrade in order to accommodate all of the building load. As this is a 24/7 patient occupied building, we would recommend adding a second electrical service to segregate the new A and B Wing loads and allow for construction without losing power to the existing building. Preliminary service has been shown in order to plan for a future new service transformer but is not included in the project.

feeders/breakers originating from/in the existing Main Switchboard MSB.

accordance with the space program requirements, the VA design guides and the International Energy Code.

2. Wall-mounted bed light fixtures in single bed patient rooms will consist of an upward and downward lamp with a 2-position on-off pull cord control of the downward portion of the light.

3. Exit light fixtures will be LED type with red lettering and a brushed aluminum finish. Fixtures will be single or double-faced with directional arrows as required. Fixtures will be circuited to generator backed essential power.

2. Indoor ceiling-mounted occupancy sensors will be dual technology, automatic off/manual on, low voltage type. Ceiling-mounted sensors will be utilized in open offices and larger spaces where coverage by ceiling is required. Sensors will include all required digital room controller, power packs, etc. for a complete control system. Wall-mounted override switches will be included.

3. Daylighting sensors will be automatic dimming, digital style photo-sensors compatible with the digital room controllers to interconnect with occupancy sensors and lights. Sensor will allow for foot-candle set points from 20-60 fc. Sensors will be set at 5 fc greater than the required average maintained illumination in the space.

4. Standard manual light switches will be quiet toggle type or paddle/slide 0-10V wall dimming type, specification grade and ivory in color as required by the VA design guide. Manual light switches will be utilized in spaces where automatic control of lights is detrimental to the occupant, such as in electrical and mechanical rooms.

2.4 HVAC system:

The system will be designed to meet the air-change and pressure relationship requirements for the different space types, with ducted supply, return and exhaust air systems. All ducted perimeter rooms with windows will be provided with linear diffusers. Interior ducted spaces will be served by square supply air diffusers. associated materials as specified on the drawings and in specifications.

The HVAC system will consist of two central VAV Air Handling Units with chilled water and heating hot water each serving a wing with single duct VAV air terminal units with hot water reheat coils serving their respective zones. Restroom exhaust, general exhaust, and relief air will be directed to Energy Recovery Ventilators (ERV), one per wing, serving their respective VAV Air Handling Units. Chilled water will be extended from the central campus chilled water loop. Steam will be extended to the building, pressure reduced to low pressure steam and converted to heating hot water with a steam to water heat exchanger.

The central utility connections are existing system connections. It is also the requirement of the EKVAHCS maintenance staff to have this system operate off the central steam and chilled water system.
