SCOPE OF WORK

REON team surveyed 32 elevators on November 27, 28, and December 3, 2018. The purpose of the audit and systems analysis is to develop scopes, cost estimates, time schedules, phasing for the interim repair projects, and a plan for the modernization projects. The team also identifies the primary equipment, determines the maintained condition of major components, records operating performance levels, and evaluates the vertical transportation based on applicable industry and code standards.

EXECUTIVE SUMMARY

The original equipment in the Robert F. Kennedy Building was manufactured and installed by Otis

Elevator Company in 1935, with some component systems original as installed. Several modernizations and repairs have occurred over the life of the building. The last major modernization was performed from

1992 to 1994 on all but the two private elevators, with the passenger elevators group receiving new controls and historical signal fixtures. Cabs were also incorporated into the scope. Replacement parts on the drives consist of rebuilt components.

The Robert F. Kennedy Building is located at 950 Pennsylvania Avenue, NW, Washington, DC. It is a government owned building currently occupied entirely by the Department of Justice (DOJ). General

Services Administration (GSA) has given delegation authority to DOJ for the operations and maintenance of the building. The building has nine levels and an area of 1,257,300 gross square. The passenger elevators service eight levels with stops at B, 1-7; two of the service elevators service nine levels with an additional stop at PH; and one service car serves the sub-basement level.

The REON team performed a comprehensive survey of the elevator equipment at the referenced property from the week of November 27 through December 3, 2018.

1. The office building’s vertical transportation is provided by 26 passenger elevators (9 groups) of overhead gearless traction passenger elevators and 1 hydraulic elevator. The passenger elevators serve 8 front openings (B, 1-7), have a capacity of 2,500 pounds or 3,000 pounds, and operate at 600 feet per minute with 2:1 roping. The hydraulic elevator has a capacity of 3,000 pounds and 2 stops and travels at 113 to 129 feet per minute.

2. The office building’s service/staff transportation is provided by four single dedicated service/freight elevators. Two service/freight elevators serve 8 front openings (B, 1-7) one has 9 stops (B, 1-8) and one has 10 stops (BR, B, 1-8). All have a capacity of 5,000 pounds and operate at 300 feet per minute with 2:1 roping.

3. The office building has two single dedicated private elevators. The elevators serve 6 front openings

(B, 1- 5), have a capacity of 1,200 pounds, and operate at 450 feet per minute with 2:1 roping.

Realizing that preventive maintenance is an ongoing process, the survey represents a snapshot on a specific day and time. Overall, the equipment is in good condition with evidence of preventive maintenance being performed on a regular basis. The machine room spaces are clean, and the areas are organized. The deficiencies found can be addressed during regular preventive maintenance component replacement procedures such as replacement of worn hoistway door pick-up rollers and replacement of the tail sheave assembly related to the steel tape leveling system.

Maintenance and test paperwork in the elevator machine room were found to be out of date. Record keeping of maintenance procedures was one or two months behind, and code-required test tags and firemen’s service monthly testing logs were missing from the machine rooms.

Washington, DC

The elevator control equipment for all elevators in the Robert F. Kennedy Building is obsolete by design.

Parts availability of the Armor KONE TMS 900 control systems on typical elevators is an inherent problem, being no longer supported by the manufacturer. The two private elevators have a CENTEK, Inc., control system installed by KONE during the period in which the two companies had partnered. The relationship ended, making these units likely to become obsolete soon. In addition, the CENTEK control system lacks remote monitoring capability. Boards no longer are readily available for the KONE

TMS900. In addition, the elevator control system for the 26 passenger and 4 freight elevators has exceeded its expected life. The HVAC systems in each elevator machine room appear to be from the

1992-1994 modernization period, and several units did not appear to be operational.

The elevator controls should be budgeted for replacement within the next one to two years due to lack of both spare parts and availability of technical support. Current codes require the addition of elevator rope grippers to prevent unintended movement in the up direction and may require overhead mounting due to clearance issues in the machine room during any modernization.

The typical passenger and private elevators have Otis gearless traction machines and are operating as designed. They are original to the building, making some components 83 years old. The service cars have geared traction machines that are 25 years old. Gearless permanent magnet A/C machines and regenerative drives shall be provided for all passenger gearless applications and new geared traction machines with A/C drives on geared applications.

The passenger elevator hall fixtures (hall call buttons, position indicators, and hall lanterns) are of historic style and currently are in poor condition. They are using incandescent bulb technology, which requires more frequent bulb replacement compared to LED lamps. Original hall fixtures are recommended to be refinished and upgraded with LED bulbs and all others to be replaced with new matching fixtures on levels 1-5. This work should be coordinated with the elevator control upgrades that have been replaced to match historical style and shall to be completed with elevator modernization. Due to the unique cast aluminum fixtures associated with the 26 passenger elevators, cars and hall fixtures for all 25 elevators should be purchased at one time/single package under the first phase of the project. Doing so will ensure best pricing and matching fixtures. And if modernization is split into different projects, etc., then everything will match, and there will be no chance of a different vendor manufacturing custom fixtures.

Pit lighting appears to be adequate, but some new fixtures will be required. All pits were dry with little to no evidence of water/moisture intrusion. However, sump installation will be required during the controller change to meet current codes. GFCI electrical outlets also need to be provided in each pit. Cat walks will be required to enable inspection of the pit buffers of each passenger elevator.

Some passenger elevators have what appears to be a new cab replicating the original cabs. These cabs are to be repaired/refinished. A complete cab replacement is required for non-historical cabs. The existing cabs have aluminum and stainless-steel cove ceiling, wall panels and car doors, flat bar stock stainless steel handrails on side and rear walls, tile flooring, and original car operating panels (main only). All cabs are ventilated by a cab fan mounted on top of each elevator cab shell. There are vents in the base of each cab.

The four service/freight elevator cabs are to be repaired/refinished. The existing cabs have fluorescent fixtures mounted flush with the ceiling, steel shell cab, with three rows of oak bumper rails on side and rear walls, checker plate flooring and stainless-steel car operating panels (main and auxiliary). Ventilation of all cabs is achieved by a cab fan mounted on top of each elevator cab shell. There are vents in the cab base/ lower bumper rail.

Private elevators have what appears to be a standard cab with laminate panels. A complete cab replacement is recommended for non-historical cabs. The existing cabs have eggcrate ceilings, plastic laminate faced paneling, flat bar stock stainless steel handrails on side and rear walls, carpet flooring, and bronze car-operating panels. All cabs are ventilated by a cab fan mounted on top of each elevator cab shell.

The elevator machine rooms for typical passenger cars and service cars 10, 24, and 31 are located on the penthouse level. Service elevator 24’s machine room is offset adjacent to the hoistway with a sheave room above the hoistway separated by metal grating. The service elevator machine room for elevator 40 has a dedicated spiral staircase to the machine room. Private elevators number 11 and 23 have a machine room located on the sixth level.

There are 15 elevator machinery rooms (EMRs) in the RFK Building; 9 serving passenger elevators; 1 serving the 2 private elevators; 4 serving the 4 freight elevators and 1 serving the 2-level hydraulic elevator. There are two A/C system types cooling the rooms. The passenger, private, and hydraulic EMRs are cooled by self-contained A/C units, water cooled by an ethylene glycol distribution system with the heat rejection at rooftop mounted dry coolers. The freight elevator EMRs are cooled by through-the-wall packaged terminal air conditioning (PTAC).

The systems were installed in the 1980s and have reached the end of their useful life, typically 25 years.

The systems, when installed, were adequately sized. However, time and controller changes have rendered the systems ineffective. It is recommended that the existing cooling systems be removed and new systems installed.

The report requires that sump pumps be added to the elevator pits that will be tied into the emergency power systems to ensure reliability and reduce risk of flooding.

Emergency power systems will be incorporated into servicing the elevators, the elevator machine room cooling, the sump pumps, and the lighting (as required) to meet the current codes when modernization or other significant work in these areas is undertaken. The electrical scope of work will require new power to major elevator and mechanical equipment. To meet code, the incorporation of new energy-efficient low-maintenance LED lighting into both the elevator machine rooms and the pits and the upgrading of power outlets to GFCI is recommended during modernization.

Several elements of fire protection will be required as part of the elevator modernization, summarized as follows: elevator recall, fire and smoke alarm/detection, and fire suppression. These systems do not exist, so to meet code requirements, they will need to be added at the time of modernization or other significant renovations that touch these areas. These will be required to meet the Elevator & Escalator Safety Code

ASME/ANSI A17.1, IBC, GSA P-100, and NFPA (13, 70, 72, and 101). This building is taller than two stories, which means that the recall will have to be integrated into the fire alarm system. The current system is lacking an integrated recall system and will need to be incorporated. The new sprinkler work will meet the most recent codes at the time of contract award. This work will include demolition of the existing machine room and shaft sprinkler protection system and replacement with new as required by code.

The elevator shafts are masonry and considered to provide fire rating. Reconstruction of the shafts would not be feasible given the historical context of this building. The designer of record for the modernization will need to perform a comprehensive survey to make required corrections at the time of the modernization.

CODES AND STANDARDS REVIEW – ELEVATORS ONLY

All passenger and service elevators in the Robert F. Kennedy Building were upgraded between 1992-94.

The private elevators were last upgraded in 2007. The present components are a mixture of old (machine, car, counterweight, pit equipment, fixtures), and new (SCR drives and door operator). The systems do not meet the latest code regulations in the following areas:

1. Firefighters’ elevator provisions should be addressed where possible.

2. Emergency power selection panels contain elevators that do not exist and should be replaced.

For purposes of this evaluation, IBC 2018, which references Elevator A17.1-2016, was used as the basis of comparison.

IBC 2018 – Chapter 30

1. Section 3001.2 – Emergency elevator communication system for deaf, hard of hearing, and speech impaired.

2. Section 3003.1.4 – Venting – machine room HVAC must be connected to standby power.

Annual Safety Inspection (Cat 1): All tests are performed at inspection speed with no load inside the elevator. Manually activate the safeties, governor, emergency final limits, over speed switch, door locks, gate switches, car door restrictors, stop switches and buffer switches. Activate Fireman’s Service Phase I

& II. Test emergency lighting / alarm / communications. Test the door protection devices and closing force. Unintended movement device is also verified.

3-Year Test (Cat 3 for hydraulic elevators): This type of testing is required only if the unit has a pressure vessel (hydraulic valve) as a means of propulsion. The pressure vessel must be charged at maximum pressure for 15 minutes without changes to pressure. A visual inspection inside of the vessel is also performed.

5-Year Full-Load (Cat 5): Same scope of work as the Cat 1 no-load test, and also while elevator is operating at contract speed. Conduct a full-load (elevator capacity) safety drop test, 125% capacity elevator brake test, and a full load buffer test. Manually test the governor activation speeds and governor pull through.

What the 5-year test involves and what is expected at the end of the test: The elevator is loaded to maximum designed capacity and with the elevator traveling in the down direction; the speed governor is activated to put the elevator on emergency stop. The distance of slide on the main elevator rails is then measured for tolerance as well as the level of the elevator itself after the emergency brakes (safety) are applied and the car has come to a complete stop. After this is completed, the elevator is further tested in the down direction (under full load, contract speed) and strikes the elevator pit buffer. The elevator then is lifted, and the buffers (oil type) must return to original position within 90 seconds. Additional weight is added (25% of capacity) to the cab. The elevator is tested again in the down direction and must stop within normal leveling tolerances between the car and hoistway entrance sills. All tests have specific tolerances set by ANSI A17.1 in relation to the elevator design: type, speed and capacity.

Accessibility: The RFK Building was built in 1935. At that time, the federal buildings were not required to meet accessibility standards. Renovations after 1984 were required to meet the Uniform Federal

Accessibility Standards or (UFAS) which was superseded by the Architectural Barriers Act (ABA)

Accessibility Standards (ABAAS) in 2006. Features that are compliant with the UFAS may remain as is unless those features are being altered, then they must be upgraded to current ABAAS requirements unless it is “technically infeasible” to do so (ABAAS F106.1). If a feature did not meet the original UFAS requirements, then it must be upgraded to current ABAAS requirements. For clarity, the Americans with

Disabilities Act and ADAAG do not apply to federally owned facilities. This building is a federally owned facility, not a leased facility. While the standards are similar, the survey is based on compliance with

ABAAS.

Mechanical Equipment Survey

The team performed a survey of the existing elevator machine rooms with some limited documents provided. In summary, there are 15 elevator machine rooms (EMRs) in the RFK Building; 9 serving passenger elevators; 1 serving the 2 private elevators; 4 serving the 4 freight elevators and 1 serving the 2-level hydraulic elevator. Throughout the building, there are two A/C system types cooling the rooms. The passenger, private, and hydraulic EMRs are cooled by self-contained A/C units, water-cooled by an ethylene glycol distribution system with the heat rejection at rooftop mounted dry coolers. The freight elevator EMRs are cooled through the wall packaged terminal air conditioning (PTAC). The PTACs are not part of the BAS. BAS systems were not surveyed in this report, but all new systems would be required to be integrated into the BAS at the time of modernization. The conditions of these systems vary from EMR to

EMR, but generally they are out of date and should be modernized with the elevators. The systems were installed during the 1980s and have reached the end of their useful life, typically 25 years. The systems, when installed, were adequately sized. However, time and controller changes have rendered the systems ineffective. The pages that follow are the survey notes and load calculations for each of the systems.
