Project Overview and Background

The Ioannis A. Lougaris Veteran’s Administration Medical Center, also known as the VA Sierra Nevada Health Care System (VASNHCS) and component of the VA Sierra Pacific Network (VISN 21), provides primary and secondary care to a large geographical area that includes 20 counties in northern Nevada and northeastern California.

In addition to the main campus, at 975 Kirman Avenue in Reno, the VA Sierra Nevada Health Care System also includes four patient care sites within the Reno and Sparks area. These patient care sites are detached from the main campus. These sites include two primary care sites at the North and East campuses and Dental and Eye Clinics.

Further, the VASNHCS also offers services in three community-based outpatient clinics (CBOC) and one rural outreach clinic. These clinics include the VA Carson Valley Outpatient Clinic in Minden, Nevada, the Lahontan Valley VA Clinic in Fallon, Nevada, the VA Diamond View Outpatient Clinic in Susanville, California, and the Winnemucca Rural Outreach Clinic in Winnemucca, Nevada.

Building 8 is the existing Central Utility Plant that serves the campus.

This is a single-story building that is located between the main hospital and the parking garage.

This project to create bridging documents for a new Central Utility Plant that to be in the existing parking, just north of Building 8. In addition to housing the MEP systems, additional functions will be provided (programming). Placing the new building here, would displace existing handicap parking. The existing gravel parking lot on the corner of

Kirman Avenue and E Taylor Street will need to be paved and stripped to accommodate new handicap spaces.

Security

Based on risk assessment conducted on November 26th, 2019 in support of “Seismic Retrofit Project Book, Buildings 1D, 8, 10, 12 – Project #s 654-212, 654-101, 654-112, and 654-877” a “Physical Security SITE Design Guide Refresher – Reno Bldg 8 CUP” and “Blast Protection Design Guidance – Reno Bldg 8 CUP” reports were produced for the AE and VA. These reports, each considered “Controlled Unclassified Information” per PSDRM 1.9. However, the

LEED

Per the SOW, the New Central Utility Plant will be designed to achieve a LEED Silver Rating.

The design build team that is awarded the full construction drawings and construction, will be responsible for the certification process and associated fees.

Existing Access to Parking Garage

Currently access to the parking garage, ground floor, is through two entrances. There is one on the east side and one on the west side. The west side entry of the parking garage would pose a challenge for setback requirements for the new Central Utility Plant. Comments regarding the challenges and possible solutions are further discussed in the Design Options.

Existing Site Conditions

The existing Boiler Plant (BP) site is located southeast of the intersection of Kirman Avenue and Belli Drive. North of the existing BP is an asphalt parking lot that contains many accessible parking spaces and general spaces for users of the VA hospital. The new Century Utility Plant

(CUP) will be constructed within the existing parking lot. The parking lot is bounded to the east by a two-story parking garage and the existing BP is adjacent to a maintenance building.

Existing vehicle access to the parking lot is provided from two curb-cut entries along the one-directional Kirman Avenue. Pedestrian access to and through the site is primarily through a large concrete walkway that separates the parking lot and the existing BP. The existing parking lot houses 26 accessible spaces and 29 standard spaces. The access drives within the parking lot serve as an entry and exit point to the lower levels of the existing parking structure.

The existing BP site and parking lot are almost entirely impervious, except for the small tree wells located along the east side of Kirman Avenue right-of-way. Surface runoff drains east toward grate inlets adjacent to the existing parking garage and maintenance buildings. These flows are collected and conveyed via storm sewer to the east.

Just north of the hospital, at the northeast corner of Kirman Avenue and Taylor street, is an existing gravel parking lot. This lot will be paved and reconfigured as part of this project. The existing parking lot serves government vehicles and entirely comprised of a compacted gravel parking surface. Existing runoff flows to the southeast corner where a small depressed area provides a small amount of attenuation. Excess flows exit the attenuation area through a curb cut in the Kirman Avenue sidewalk and convey to an existing inlet in Taylor Street. The existing parking lot has two entries, one on Kirman Avenue and one on Taylor Street.

Existing Utilities

The existing Boiler Plant has serval incoming and outgoing services including steam, natural gas, chilled water, oxygen, and electric. The BP supplies oxygen, steam, and natural gas to the main hospital across the street. Returning from the hospital is a condensate return line and a chilled water line. An existing utility tunnel provides a conduit for the majority of these utilities between the hospital and the existing BP. The tunnel runs under Kirman Avenue, through the existing parking lot, and enters the existing BP on the east side.

654-212 (1791.06)

CENTRAL UTILITY PLANT

Electrical services for the BP are pulled from overhead power lines that run along the east side of Kirman Avenue. Several transformers are located behind an enclosed courtyard north of the existing BP. Lighting for the existing asphalt parking lot is provided by street lights within the parking area.

During construction of the new CUP, services to the existing BP will remain operational throughout. Temporary rerouting of the utilities within the existing utility tunnel will be necessary.

While several existing utilities are located within the Taylor Street and Kirman Avenue rights-of-way, there are no known existing utilities within the existing gravel parking lot.

Plumbing for existing boiler plant is minimal and is partially sprinkled. The existing 6” water lines are located in Kirman Avenue and Belli Drive. Existing fire hydrant is located on east side of Kirman and Belli intersection. The chilled water and oxygen lines are located inside the existing tunnel.

An existing 15” SDR 35 sanitary sewer is in Kirman Avenue and 12” SDR35 sanitary sewer line is directly south of the existing boiler plant. An existing 18” RCP storm sewer and fiber optic line are also directly south of the existing boiler plant. An existing 2” XTC gas line in

Kirman Avenue feeds to the boiler plant from west side.

Site Considerations

The project will construct the new Central Utility Plant (CUP) within the area of the existing asphalt parking lot. The geotechnical engineering report has been completed by Terracon

Consultant on October 12th, 2022. One-way traffic Kirman Avenue is to the west and two-way traffic Belli Drive is to the north of the site. The existing parking structure just to the east of the site has two access points for the lower level. One is located on the east side of the structure, while the other is on the west side and is currently accessed via the access drives of the existing parking lot. The new CUP requires a minimum 50-foot standoff from all unscreened vehicles. Because of this requirement, the west garage entry will be closed as part of this project. Closure will be achieved through the addition of anti-ram bollards installed along the entry. Access to the existing maintenance building and maintenance areas east of the site, which is currently provided through the existing asphalt road, will be provided through a new

24-feet wide, two-way access drive. This access drive will also provide fire truck access to those areas.

The new CUP building and surrounding flatwork areas will be enclosed within a fence and gate system. The gate and fencing system will be PSRDM compliant, 8-feet minimum in height, constructed of ornamental steel, and feature anti-climb features. Fence sections adjacent to

Kirman Avenue and Belli Drive shall be anti-ram enhanced. Options to achieve this are to purchase sections of fence that are anti-ram rated or lining the interior sides with rated guard rail. A sliding vehicle gate will be located on the west side of the compound at the location of the existing curb-cut in Kirman Avenue. This gate will feature security elements recommended within the security section of the design narrative but at a minimum shall be equipped with dual-authentication access control using person identification and license plate recognition.

Two pedestrian access gates will be located south of the CUP. Both gates shall include security elements recommended in the security section of the design narrative but at a minimum shall be equipped with personal identity verification, PIN code entry, an auto-closer, and an anti-prop alarm.

Storm runoff from the CUP and yard areas will be collected in storm inlets along the east side of the building. A pervious area will provide some attenuation of flows from the site, as well as

654-212 (1791.06)

CENTRAL UTILITY PLANT

Choose an item. 4 providing water quality treatment of storm water. Flows from this water quality basin will be collected in a new outlet structure and conveyed to the existing storm sewer system.

The repaved gravel parking lot to the north will act as temporary parking for displaced accessible parking spaces following the demolition of the asphalt parking lot north of the existing BP. The new parking lot will eliminate the existing curb-cut entry on Kirman Avenue and all access will be via the existing Taylor Street access. Removal of the Kirman access will allow additional parking and better circulation through the parking lot. Coordination with the

City of Reno will be required during the removal of the curb cut as it is expected that some traffic control measures will be necessary during construction.

A new detention and water quality basin will be added to the southeast corner of the parking lot. Flows from the detention pond will be conveyed to the back of an existing inlet in Taylor

Street. Again, coordination will be required with the City of Reno for construction within the

ROW. Emergency overflows from the pond will be conveyed via existing sidewalk chase, as in existing conditions.

New Utilities

New utility services will be provided to the new CUP from the mains within Kirman Avenue.

Services include domestic water, wastewater, and natural gas. The existing utility tunnel carrying several utilities between the hospital and the existing BP will be connected to the new

CUP. The existing utilities within the tunnel must remain in service until the new CUP is fully completed and accepted by the VA. Temporary rerouting of the tunnel utilities will be required during construction. New utility service connections that extend into public ROW will need to be coordinated with the City of Reno for any lane or roadway closures required.

Parking Considerations

South of the new Central Utility Plant will be a new asphalt parking lot. The parking lot is divided into two sections. One section will be dedicated to accessible parking for the hospital patrons, and the other section will be for workers of the new CUP. The portion of parking that is dedicated to CUP workers will be within the 50-feet setback and therefore will be feature

654-212 (1791.06)

CENTRAL UTILITY PLANT

Choose an item. 5 gates to prohibit access by non-screened vehicles. The gates will be drop arm and feature security elements outlined in the security section of this design narrative.

To construct the new CUP building, the entire asphalt surface parking lot will be demolished, displacing 26 accessible spaces and 29 standard spaces that serve the existing hospital. The accessible spaces will be temporarily relocated to the newly repaved parking lot at Taylor and

Kirman. The lot will be temporarily striped to allow these additional accessible stalls. Once the parking lot to the south of the CUP is completed, a large portion of the accessible stalls will be moved to the new lot. The entire parking lot will then be restriped for the final configuration which will feature some accessible spaces and some standard spaces.

Site Construction Phasing

To allow the existing Boiler Plant to remain operational and to minimize impact to the hospital, the project will be phased. The phasing will be as follows:

1. Phase 1 – Construction of “Off-Site” parking lot at Kirman and Taylor.

a. The new asphalt parking lot will be temporarily striped to maximize the number of accessible parking spaces that will be displaced through the demolition of the lot north of the BP.

2. Phase 2 & 3 – Secure the site, demo/reroute utilities, and construction of new Central

Utility Plant (Building 16)

a. Demolish existing asphalt parking lot and temporary relocation of tunnel and site utilities that are serving the existing BP.

b. Reroute pedestrian pathway north of the existing BP to a temporary walkway and close off west entrance to the parking garage.

c. At completion of this phase, and after acceptance of the new plant by the VA, the existing utilities to the BP can be shut down.

3. Phase 4 – Demolition of Existing Boiler Plant (Building 8)

4. Phase 5 – Construction of new parking lot south of new CUP

5. Phase 6 – Restriping of “Off-Site” parking lot at Kirman and Taylor

a. The parking lot will be restriped to remove many of the accessible spaces and replace them with standard spaces.

The VA Sierra Nevada Healthcare System (VASNHCS) in Reno, Nevada requires the development of design and construction documents for a Central Utility Plant (CUP) to replace existing Boiler Plant (Bldg. 8). Existing Boiler Plant has aged and need to be replaced with a new and/ or modern facilities to serve the VASNHCS campus. The intent of this narrative is to provide an Electrical Schematic Design document for the Department of Veteran Affairs (DVA) Office of Construction and Facilities Management (CFM) for both design and construction execution.

B. Scope of Work

The Electrical (Division 26) Scope of work shall include the following:

i. Assessment of existing electrical service for the VASNHCS campus,

ii. Assessment and evaluation of existing and anticipated future loads for the new

CUP,

iii. Provide a schematic design for a new electrical service and emergency power system to support new CUP,

iv. Provide schematic design for general power distribution and lighting in new

CUP,

v. Provide a schematic design to size an Uninterrupted Power System (UPS) to support critical equipment during power outages/interruptions,

vi. Provide parking lot lighting for new gravel parking area north of VASNHCS campus.

C. Background

The VASNHCS campus is served by a 3-phase, 60Hz, 115A, 24.9kV Medium Voltage (MV) from NV Energy Company of Nevada (see Appendix A). There are two independent substations (Sutro 241 and Holcomb 241) serving the VASNHCS campus. Both feeds are delivered to the VASNHCS Campus via overhead distribution lines and transition underground through an electrical vault to utility metering enclosure / MV switches in the courtyard of existing Boiler Plant (Bldg. 8). The peak load recorded for the VASNHCS campus is 1.84MW. The VASNHCS power distribution loop originates from the MV switches to various buildings on campus via an underground electrical vault outside of the Plant courtyard. The Plant is served from a 2500kVA, 24.9kV – 480Y/277V, 3-phase pad mounted transformer. The service transformer feeds the main electrical service disconnect switch for parking garage /Building 15 and SE08 (service entrance switchboard) for existing Boiler Plant. The Switchboard (SE08) is rated 3000A, 480Y/277V, 3-phase and located in the courtyard of the Plant.

The plant (Bldg. 8) includes three (3) boilers, three (3) chillers, four (4) cooling towers, a cooling tower sump pit, the facility’s main HVAC system control computer/monitors, and a Command Center. The Plant also serves as the main or back-up location for all

654-212 (1791.06) Central Utility Plant
