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The Montgomery and MCE controllers are outdated, and the support and technician's knowledge of this product is limited.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

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.

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.

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.
