Phase I Fire Service Yes Yes GENERAL Elevator components were surveyed to determine overall condition and suitability for continued use in conjunction with a modernization or replacement. In addition, machine room, hoistway, and pit spaces were reviewed for compliance with current codes. This section reviews the results of our equipment survey. EQUIPMENT DISPOSITION Elevators 1 through 6 are Overhead Traction Cars manufactured by Haughton Elevator in 1969. Cars 1-5 are gearless and car 6 is geared. These elevators were modernized approximately 15-20 years ago by Montgomery Elevator and the Ultron controllers, door operators and fixtures were installed. The hoist machines are the original equipment. Elevators 1, 2, and 3 have a rated capacity of 4000lbs. and a rated speed of 400fpm and serve levels 1 thru 7. Platform size is approximately 7'-6"" wide x 5'-6"" deep. Entrances are 4'-0"" wide x 7'-0"" high, single speed center-opening doors. Elevators 4 and 5 have a rated capacity of 5000lbs. and a rated speed of 400fpm, serving levels 1 thru 7. Platform size is approximately 5'-8"" wide x 8'-0"" deep. Entrances are 4'-0"" wide x 7'-0"" high, Two-Speed side-opening doors. Elevator 6 is a simplex 5000lb car and rated speed of 200fpm and center-opening single-speed doors. Car 6 has a walk-in pit. Elevator 9 is a simplex 4000lb in-ground hydraulic car manufactured by General Elevator in 1979. It has a rated speed of 125fpm, and adjacent machine room, and side-opening two-speed painted doors. The aluminum head should be changed as soon as possible, these heads are not considered safe. Cars 10 and 11 are geared overhead traction duplex elevators with a rated capacity of 5000lbs. and a rated speed of 400fpm. They serve levels 1 thru 7. Platform size is approximately 5'-8"" wide x 8'-0"" deep. Entrances are 4'-0"" wide x 7'-0"" high, single- speed center-opening doors. The cab interior was recently refurbished. Elevator 18 is a simplex in-ground hydraulic 4000lb car manufactured by General Elevator in 1981. It has an MCE controller and a rated speed of 125fpm, and side-opening two-speed painted doors. The machine room is adjacent. The overhead space appears to be less than code compliant and may require a variance. The existing elevator equipment is in average condition for this vintage of equipment. The Montgomery and MCE controllers are outdated, and the support and technician's knowledge of this product is limited. Changes in equipment design and technology have made many improvements with dispatching, motor control, and door operation that will greatly benefit the facility. Door equipment and operators are past their life expectancy, replacement parts are likely difficult to obtain. Advances in door technology have resulted in improved passenger safety via closed loop operation. Existing signal fixtures such as Car Stations, Hall Stations, and Hall Position Indicators show dents and abrasions, are dated and past life expectancy. The elevator cab interiors are dated and show damage such as chipped laminate and dented metal wall panels. These are significantly past life expectancy. Hydraulic elevators No. 9 and No. 18 pumping units and machines are recommended for replacement. The original machines have had a previous modernization. The existing pit depth of 4 -0 will limit cars No. 9 and No. 18 to utilizing hydraulic equipment only. Either a holeless twin-post system or in-ground jack with sealed PVC casing system is acceptable. Overhead space on car No. 18 will need an additional survey to determine overhead height under hoistbeam from finished floor of last landing. For the traction units, these should be replaced with AC machines with VVVF controls, which consume less power and produce less heat. A second option would be to utilize machine-roomless elevators. According to the building plans provided, there is sufficient overhead space available for Cars 1-6, 10 and 11 for either application. While conventional overhead gearless machines are more expensive than machine-roomless equipment, they will have a longer lifespan and be more reliable in the long run. Machine-roomless applications are acceptable, but there is a trade-off for having the machines located within the hoistway, the motors are smaller, and smaller motors work harder than larger motors. This results in reduced overall lifespan. CONCLUSIONS Lerch Bates recommends that all ten (10) elevators be replaced with new equipment, including machines, controllers, cabs, fixtures, wiring, and hoistway equipment. The existing entrance frames may either be completely replaced or retained and wrapped with new cladding material such as stainless steel. If the frames are to be completely replaced, then a rough-opening of 5 -6 wide by 8 -4 high would be required to be saw-cut for 4 -0 wide by 7 -0 high entrances. In addition, the hoistway sills would need to be chipped out of the existing floor slab. Therefore, we believe this would be best handled from a modernization standpoint in lieu of a New Construction stand-point simply because this an existing building. Existing conduit to be reused and may when deemed appropriate by contractor. SECTION III MODERNIZATION PLANS GENERAL In our opinion, development of a comprehensive modernization plan for the James A. Haley Medical Center should be based on the changes required to the existing elevator systems necessary to achieve reliable elevator service, passenger safety, and life safety, in conjunction with related building work necessary for code compliance. Modernization should take into consideration cost constraints as well as potential interim inconvenience to tenants during the modernization process. In our judgment, it must also represent a comprehensive, long-term (minimum 25 years) solution in order to justify capital expenditures. ANTICIPATED LEAD-TIMES Planning for modernization should include consideration of long lead times for fabrication of equipment and installation. Approximate time frame not including building work is as follows: Preparation of Bid Specification/Owner Reviews 4 weeks Bid Review and Award of Contract 6 weeks Shop Drawing Approval 8 weeks Equipment Fabrication 22 weeks Equipment Delivery 2 weeks Installation Cars 1, 2, 3 10-12 weeks each Installation Cars 4, 5 10-12 weeks each Installation Car 6, 9, 18 6-8 weeks each Installation Car 10, 11 10-12 weeks each Final Adjusting and Testing 2 weeks Total Elapsed Time for Project Vary According to Install Crew Availability EQUIPMENT DISPOSITION The Equipment Disposition Summaries attached in Appendix A provide details of specific findings and recommend APPENDIX A EQUIPMENT DISPOSITION SUMMARY ELEVATORS Remove Existing Retain Existing Recond.

MECHANICAL EXISTING CONDITIONS This report is commissioned based upon the field work and understanding of the scope of work. A site visit and assessment were performed by Above Group Inc., in conjunction with RDC / John Poe Architects and Lerch Bates on March 11, 2022. The following is based upon that site visit. The scope of this project is to modernize or replace (10) ten elevators at the James A. Haley Veterans Medical Center. The elevators to be evaluated as part this report are: 1-6, 9-11, and 18. Elevators 1-6 are Overhead Traction Cars manufactured in 1969. Elevators 1-3 share a single combined pit, while elevators 4 and 5 share a combined pit. Elevator 6 has a walk-in pit. Elevator 9 is an in-ground hydraulic car manufactured in 1979. It has an in-ground pit not connected to any other elevators. Elevators 10 and 11 are geared overhead traction duplex elevators and share a combined pit. Elevator 18 is a simplex in-ground hydraulic car manufactured in 1981 and has an in-ground pit separate from all other elevators. Pits serving Elevators 1-6, and 9 are sprinklered but a sump pump was not observed during the site visit. The pit serving Elevator 18 is also sprinklered but contains a sump pump while the pit serving elevator 10 & 11 is not sprinklered and did not contain a sump pump. Elevators Served Sump Pump Sprinklered 1, 2, 3 No Yes 4,5 No Yes 6 No Yes 9 No Yes 10,11 No No 18 Yes Yes Elevator equipment is contained within existing elevator machine rooms located above the 7th floor for elevators 1-5, 10 and 11. The equipment rooms for elevator 6 is located above the top floor it serves while equipment rooms for 9 and 18 are located in the basement. Equipment serving elevators 1-5 are housed in one machine room. Equipment serving elevators 10 and 11 are contained in a separate machine room. Equipment serving elevators 6, 9, and 18 are located in separate, individual machine rooms. None of the machine rooms were observed to have dedicated HVAC systems serving the machine room only. The machine room serving elevators 1-5 had HVAC routed from an adjacent server room into the machine room. The remaining machine rooms (6, 9, 10&11, 18) do not have HVAC cooling; they are only served by exhaust fans and outdoor air louvers. RECOMMENDATIONS All elevator pits for elevators that have Firefighters Emergency Operation shall have a drain or sump pump in accordance with ASME A17.1 Section 2.2.2.5. The drain or sump pump shall discharge into the sanitary or storm drainage system through an indirect waste connection. The sump pump or drain shall have the capacity to remove a minimum of 3,000 gallons per hour per elevator car (50 GPM per car). In hydraulic elevator pits, separators shall be installed into which an all oil-bearing, grease-bearing or flammable wastes shall be discharged before emptying into the building drainage system or other point of disposal. However, an oil separator is not required in hydraulic elevator pits where an approved alarm system is installed and an indirect waste connection is provided. Elevators Served Sump Pump Sprinklered 1, 2, 3 New 150 GPM To be modified 4,5 New 100 GPM To be modified 6 New 50 GPM To be modified 9 New 50 GPM (oil-minder) To be modified 10,11 New 100 GPM To be installed 18 New 50 GPM (oil-minder) To be modified All elevator machine rooms are required by International Building Code 2021 Section 3005.2 Venting to have independent ventilation or air-conditioning to protect against overheating. Elevator machine rooms, machinery spaces that contain the driving machine, and control rooms or spaces that contain the operation or motion controller for elevator operation shall be provided with an independent ventilation or air-conditioning system to protect against the overheating of the electrical equipment. The system shall be capable of maintain temperatures within the range established for the elevator equipment. Given that all of the machine rooms do not have independent air conditioning systems, only exhaust systems, it is recommended that as part of this project new, split-system air conditioning systems be provided for each elevator machine room to control the equipment room space temperatures. It is estimated that each machine room will have a unit that is sized at approximately 1-1/2 tons per elevator machine within room. Existing exhaust fans will be removed and louvers will be blanked off. Elevators In Machine Room Recommended HVAC Sizing 1, 2, 3, 4, 5 7-1/2 tons 6 1-1/2 tons 9 1-1/2 tons 10, 11 3 tons 18 1-1/2 tons ELECTRICAL EXISTING CONDITIONS This report is commissioned based upon the field work and understanding of the scope of work. A site visit and assessment were performed by Above Group Inc., in conjunction with RDC / John Poe Architects and Lerch Bates on March 11, 2022. The following is based upon that site visit. The scope of this project is to modernize or replace (10) ten elevators at the James A. Haley Veterans Medical Center. The elevators to be evaluated as part this report are: 1-6, 9-11, and 18. Elevators 1, 2, 3, 4 and 5: Each elevator is fed from a 100A disconnect switch in the 7th floor elevator machine room, which is in turn fed from a 125AF/100AT shunt-trip circuit breaker in existing panelboard MB9 (Equipment Branch; 400A MCB; 480V, 3 phase, 3 wire; Eaton PRL3a series). Each elevator s cab lighting is fed from a 30A disconnect switch mounted adjacent to each respective elevator controller, which is in turn fed from a 20/1 branch circuit breaker in existing panelboard X.3.A (Normal Branch; 125A MLO; 208Y/120V, 3 phase, 4 wire; GE A series). Lighting footcandle (fc) overview: Elevator machine room: Lighting exceeds code minimum of 20fc, except at 1 corner where a measurement of 10.1fc was observed. See image below: Secondary overhead machinery spaces: Lighting does not meet code minimum 20fc. Elevator sills in lobby space: footcandle measurements were taken at the sill of all (8) floors serviced by each elevator. All measurements met or exceeded the code minimum 10fc when the elevator doors were open. Elevator pit: Lighting does not meet the code minimum 10fc. Fire alarm observations: Smoke detectors were appropriately in place in the elevator machine room / hoistway and at every elevator lobby. Heat detectors were appropriately in place within 24 of every sprinkler head in the elevator machine room and all hoistway sprinkler heads located more than 24 above the elevator pit floor. Only 2 fire alarm relays observed. A 3rd fire alarm relay is required for appropriate primary, secondary and fireman s hat functions. Miscellaneous observations: Elevators 1, 2, 3, 4 and 5 share a common machine room, enclosed by a wire fence. The elevator disconnects were wall mounted within sight of the elevator controllers, but were not located at the entry to the machine room.
