Scope of Work: Investigate and review existing eight (8) traction elevators: P1, P2, P3, P4, P5, S6, S7 and S8.

B.1 - Work in Progress / General Observations:

a. Continuous maintenance of elevators, specifically P2 and S7 were inoperable.

b. Elevator attendant present in elevator S6.

c. On-going demolition of floor 15.

d. Main electrical room upgrades located within basement level.

2. B.2 - Items Observed / Discussed Requiring Action:

a. Elevator Disconnect: Each elevator must be provided with a separate disconnect and surge suppressor in the machine room Per PG-18-10 – Elevator Design Manual Section 12.A. Although each elevator is provided with a separate disconnect, presence of surge suppressors were not evident within the Elevator Machine room (Penthouse Floor 17).

Recommended Solution: Provide surge suppressor on each (8) safety disconnect switch servicing the elevators.

b. Elevator Em. Power: Emergency power supply must have the capacity to operate a minimum of one elevator per group in healthcare facilities and meet the requirements found within VA Electrical Design Manual and Elevator Design Manual Section.

Currently, each elevator is protected by a shunt trip breaker fed from Panel PMRA >

1600A ATS-ELEV > Switchgear B1 > Switchgear GD-A (Building 226) > Five (5)

Parallel 750 kVA Generators (Building 226). During an event of emergency only two

(2) elevators are fully operable, all other elevators report to the nearest floor. It was discussed that the local VA would like to have all eight (8) elevators fully operable in an emergency. HVAC supporting elevator machine/control room appears to be fed from Emergency Power and is fed from Panel HVAC-PH > CMCC-PHA > ATS-

RENOVATE ELEVATORS IN BUILDING 200

Edward Hines Jr. VAMC VA Project #: 578-25-003

November 4, 2024

Recommended Solution: Due to the equipment being at or nearing the end of its useful life, engineer recommends replacement of panel boards and other equipment associated with the elevator power circuits. Refer to “VA Hines Building 200 – Facility Condition Assessment” table below on pages 14-17.

a. Fire Alarm and Protection: Per PG-18-10 – Elevator Design Manual Section 12.C, FA initiating devices, heat detectors and sprinklers must be installed as required by ASME A17.1, IBC, NFPA 13, NFPA 70, NFPA 72, and NFPA 101. The Elevator machine/control room is provided with smoke/heat detectors and sprinklers throughout with smoke detectors present within elevator lobbies on each floor. In addition, the top of each elevator shaft appears to be provided with heat detectors.

The bottom of the elevator hoistway for elevators ‘S1-S3’ is provided with a sidewall sprinkler, while no sidewall sprinkler is provided at the bottom of the elevator shaft for elevators P1-P3. Per NFPA 13 Section 9.3.6.2, “the sprinkler required at the bottom of the elevator hoistway shall not be required for enclosed, noncombustible elevator shafts that do not contain combustible hydraulic fluids.”

The top of each elevator hoistway does not contain sprinklers. Per NFPA 13 Section 9.3.6.6 and VA PG18-10 – Fire Design Manual – Table 7.4, “the sprinkler at the top of the elevator hoistway shall not be required where the hoistway for elevators is noncombustible or limited-combustible and the car enclosure materials meet the requirements of ASME A17.1.”

Fire Alarm and protection appears to be in adequate condition with useful life remaining. However, the assistance of the building’s fire alarm maintenance personnel will be needed to make final judgment on reusing or replacing the fire alarm devices.

b. Elevator car lights, alarm, GFCI receptacles, hoist way lights, and elevator pits:

During site investigation Emergency Panel 200-EL appears to be providing power to elevator misc. devices, equipment, and accessories as some of the breakers are labeled and others were not, however, it is difficult to determine/confirm.

Further investigation with the assistance of the VA will be required.

Emergency Panel 200-EL > T-EL 15KVA > 200-E3 > ATS-E3 > GDP (Building

226) > Switchgear GD-A (Building 226) > Five (5) Parallel 750 kVA Generators (Building 226).

Elevator pits do not contain GFCI receptacles and sump pumps, however, drains were present in existing elevator pits. Per 2022 ASME A17.1 Section 2.2.2.5, “…a drain OR sump pump shall be provided in elevator pit.” Elevator hoist way lights were found at each landing/opening; none found at top of the shaft. It can also be noted that the top exterior of each existing elevator car does have a maintenance light and receptacle. Although adequate lighting is provided within the elevator pit, hoist way and top it is recommended to replace the existing CFL fixtures to LED’s to help promote/meet the “Executive Order on Catalyzing Clean Energy Industries and Jobs Through Federal Sustainability” Section 208. By switching over to LED’s these have the lowest cost of ownership through the extra-long life of the LED diodes (50,000 hours+), near more than 75% energy use reduction compared to fluorescent with equivalent light output (4-32W bulbs - 128W total to deliver the same light as a 5000 lumen 40 watt LED fixture). Current industry standards have

Edward Hines Jr. VAMC trended to 100% use of LED fixtures in government owned facilities, and most private industries are using 100% LED fixtures for their lighting needs as well.

c. Penthouse Clearance Issues: Elevator P1’s and AHU-A2F’s safety disconnect switch does not have the proper 3’ clearance.

Recommended Solution: Relocate safety disconnect switches services Elevator P1 and AHU-A2F.

d. Penthouse lighting Issues: All lighting fixtures are CFL and with one lighting fixture appears to be inoperable.

Recommended Solution: Engineer’s recommendation is to replace all CFL lighting fixtures within Penthouse to LED and upgrade controls system to help promote/meet the “Executive Order on Catalyzing Clean Energy Industries and Jobs Through Federal Sustainability” Section 208. By switching over to LED’s these have the lowest cost of ownership through the extra-long life of the LED diodes (50,000 hours+), near more than 75% energy use reduction compared to fluorescent with equivalent light output (4-32W bulbs - 128W total to deliver the same light as a 5000 lumen 40 watt LED fixture). Current industry standards have trended to 100% use of LED fixtures in government owned facilities, and most private industries are using 100% LED fixtures for their lighting needs as well.

e. Penthouse unprotected conductors: Conductors are exposed/unprotected and are subject to physical damage.

Recommended Solution: Run exposed conductors within conduit to limit physical damage.

f. 1600A ATS-ELEV and 200A ATS-ELEV: Both Automatic Transfer Switch servicing either the Elevator power and the misc. elevator equipment/devices are not conforming to VA TIL Standards to be Bypass Isolation.
