1 ELEVATOR CONSULTING SERVICES, INC Italy Court Lakeville, MN Office: Fax: September 7 th, 2016 Tony Marino Parsons Field Project Manager USPS National Program Maintenance Audits Code Evaluations Specifications RE: Parsons Project B USPS Detroit P and DC Facility G Fort Street Detroit, Michigan Dear Tony; We reviewed 1 passenger and 6 freights at this site. The USPS at the Detroit P and DC in Detroit Michigan was reviewed by Thomas Branham of Elevator Consulting Services, Inc. on August 17, 18 th, My QEI number is 1339 and I am certified by NAESA. NAESA is the National Association of Elevator Safety Authorities. They are evaluated on and for the ASME 17.1 Safety Code for Elevators and Escalators, Section 8.6 of the ASME 17.1 and ASME 17.3 Safety Code for Existing Elevators and Escalators and ASME 17.2 Code for Inspectors Manual and industry standards for acceptable installation and maintenance procedures. Passenger Elevators 14 This is an employee elevator that has a high failure rate. The controller is a Montgomery MiProm, has a Montgomery 208E machine that are both obsolete. The machine drive sheave is bad due to poorly adjusted hoist ropes. KONE does not support either the controller or machine anymore and the after-market has boards but not software. The car had been down for a couple of days due to a clutch problem. This control was installed in Freights 1, 2 The elevators have a MCE IMC- SCR logic controller and a Courion PLC door controller. They also have a City number which is rare for a Post Office. The five year load tests are past due and the level of maintenance is extremely poor. There is at best call back maintenance being DETROIT P AND DC Page 1

2 performed and even that level is below par. The machine is an old Otis # 1 for elevator 1, an old Otis # 2 for elevator 2. While still viable units, the bearing housings are original and would need to be bored out to be replaced as they are considered obsolete by Otis. It is as cheaper to replace the machine as it is to refurbish the existing machines. In addition, elevator one sheave is bad and the ropes are starting to bottom on the groove due to poor tension adjustments. Freight 3 & 4 The elevators have a MCE IMC- SCR logic controller and a Courion PLC door controller. They also have a City number which is rare for a Post Office. The five-year load tests are past due and the level of maintenance is extremely poor. There is at best call back maintenance being performed and even that level is below par. The machines are Otis # 2. While still viable units, the bearing housings are original and would need to be bored out to be replaced as they are considered obsolete by Otis. It is as cheaper to replace the machine as it is to refurbish the existing machines. Freights 15A, 16B The elevators have a MiProm Ultron DDC logic controller and a Courion model D door controller. The five-year load tests are past due and the level of maintenance is extremely poor. There is at best call back maintenance being performed and even that level is below par. The machine is a Montgomery 210E machine which is also obsolete. The door equipment is obsolete and is better to be replaced now than get a surprise in the next half life cycle. We have the following recommendations. All the controllers warrant replacement. It is likely some of the machines can be retained if a new VVVF motor is used as the replacement. The door equipment is best to be replaced at this time due to the skill set of the technicians. Although parts are available now, they will not be by the end of the next life cycle and the current crop of technicians have a limited skillset on working on freight elevators. OPTION 1 Do little or nothing. This will eventually come to haunt the facility and handicap its function. Any future upgrade would be more expensive and failures will only increase in scope and quantity if left as is. It is more prudent to replace the obsolescence now than to delay it any longer. At a minimum, Freight Tech or Peelle techs should be brought in to adjust and refurbish the hoist way doors. A lot of rusted chains, chains out of stretch compliance and poor motor control is crucial to getting the doors working again in a reliable manner. Having a qualified third-party come in to do what your service company cannot or will not do is worthwhile. Budget for Option 1 Freights 1, $ 18, ea x 2 = $ 36, Freights 3, $ 18, ea x 2 = $ 36, Freights 15A, 16B $ 18, ea x 2 = $ 36, Total $ 108, DETROIT P AND DC Page 2

3 OPTION TWO The second option is for replacement of some of the equipment in a staggered list of priorities. The options from our observation of usage levels, liability and condition are: 1. Partially upgrade the freights 1, 2. Replace main and refurbish the door controllers, door equipment, upgrade to VVVF technology, retain ascending protection, replace machine, refurbish fixtures. Note, refurbishing the door equipment is making sure Freight Techs or Peelle techs go over all the doors twice over the initial six months to get them in first class condition 2. Upgrade the passenger elevators 14. Replace the controllers, keep the machines, new motor, add ascending protection, new governors, refurbish door equipment, new fixtures. 3. Partially upgrade the freights 3, 4. Includes new controllers, machines, refurbish fixtures, add ascending protection, refurbish door equipment. Refurbishing door equipment is making sure Freight Tech or Peelle techs go over all the doors twice over the initial six months to get them in first class condition. 4. Upgrade freight 15. Includes new controller, new fixtures, new machine, replacement of the motor, refurbish the door equipment The controllers for both the elevators and door equipment all warrant replacement but the priority status above stretches out the upgrade. Some door controllers can last another year if needs be but the main control equipment is more than obsolete, it is unreliable. The car would get new bumper rails, light fixtures, painted and car operating panel fixtures. The machine room would have some minor modifications for code compliance. This option includes the modifications to the machine room, electrical requirements, door equipment and an updated cab. Budget Option 2: Grand Total option 2 $ 1,434, Passenger $ 189, Door equipment 18, , Controllers , = 27, Machines , = 14, Ascending Protection -9, , Fixtures , , Labor = 75, Misc, permits, bldg work, etc = 20, Freights 1, $ 515, Door equipment 12,000 ea x 2 = 24, Controllers 27,000 ea x = 54, Door Controllers 3,000 ea x 2--- = 6, Machines 24,000 ea x = 48, Fixtures 9,000 ea x , Labor --150,000 x = 300, Misc, permits, building work---- = 65, DETROIT P AND DC Page 3

Any delay may significantly increase the cost due to the five-year agreement ending in the middle of the upgrades. The pricing is more inclusive for scope to replace all outdated or original items that cannot last at least 2 more life cycles. The options from our observation of usage levels, liability and condition are: 1. Upgrade the freights 1 and 2 both main and door controllers, door equipment, governors, upgrade to VVVF technology, add ascending protection, replace machine, fixtures, cab floor 2. Upgrade the freights 3, 4. Includes new main and door controllers, machines, door equipment, new fixtures, add ascending protection, cab floor 3. Upgrade the passenger elevator 14. Replace the controller, machine, new motor, add ascending protection, new governors, new door equipment, new fixtures 4. Upgrade service freight 15. Includes replacement of the machine and new car floors. The controllers all warrant replacement. Some can last another year if needs be but the door equipment is more than obsolete, it is unreliable. The car would get new floors as they are damaged, bumper rails, light fixtures, painted and car operating panel or fixtures. The machine rooms would have modifications for code compliance. This option includes the modifications to the machine room, electrical requirements, door equipment and an updated cab. Budget for Option 3: DETROIT P AND DC Page 4

11 EQUIPMENT OBSERVATIONS Although the facility has a wide selection of equipment, none of it is in good shape. In addition to being old, well used and suffering from a lack of adequate maintenance, the callback rate is abnormally high. Like so many of the USPS facilities, it has potential to be a lot better than it is without a modernization. However, it still needs upgrades due to obsolescence. The lack of adequate technical ability on the equipment is a factor on repetitive calls. The machine rooms are fairly clean but there is too much mischief. The lack of test tags on the governor or controller that is required by code. Late 5-year load tests. The freights have old but can be better controls. All the freights had significant flooring problems. The floor has ruts in the wood flooring. This can be somewhat dangerous to certain loads that shift during loading and unloading. The USPS team is resilient and knows how to get around problems. They do shift around as needed to use whatever elevator is running. One thing that will improve the overall operation when these units get modernized is some field training to the USPS personnel. The service vendor is supposed to be a partner on site, not a phantom. DETROIT P AND DC Page 11

12 Passenger Elevator, Evaluation of specific components is detailed below: GUIDE RAIILS AND SUPPORTS The guide rails and supports are suitable for reuse and should be retained. BUFFERS The existing oil buffers may be retained. CAR SLING The car sling (structural members which support the platform) shall be retained. PLATFORM The existing platform is suitable for reuse in modernization, and the isolation in this facility is not crucial to performance. SLIDE / ROLLER GUIDES The existing roller guides are the original units and have reached the end of their useful life. It is recommended they be replaced and upgraded. LOAD WEIGHING Load weighing is warranted in order to pre-torque the motor drives. PIT LADDER The existing pit ladders are adequate by current code and should be retained for each pit. MOTOR The motor will be upgraded to a VVVF unit to enhance energy savings. CAR DOOR EQUIPMENT The existing MAC door equipment should be replaced with similar or GAL door equipment. New operators would allow the doors to perform efficiently for an additional 20 to 30 years. New door operators would provide safer door operation, including ease of reversal, controlled closing pressure, and smoother, quieter operation. CONTROLLERS The controller is at the end of its useful life. It is not fiscally responsible to try to save this controller. New non-proprietary microprocessor-based controls are recommended in modernization. The definition of non-proprietary is where the manufacturer can support and train any technician on the equipment regardless of employer. This prevents OEM manufacturers as they will not train competitors. MACHINE ROOM DETROIT P AND DC Page 12

13 Conforming code compliant access already exists. Some main line disconnect and some 110 volt disconnect improvements are warranted, fire rating the rooms is crucial for compliance. Lighting will be added and relocation is necessary for compliance. HOISTWAY WIRING The hoistway wiring will be replaced. TRAVELING CABLES The existing traveling cables have reached the end of their useful life. It is recommended that new traveling cables be provided. CAR TOP INSPECTION STATION The car top inspection station does meet current code and but warrants relocation or a new one as it has to be accessible from the entrance. The new station should include a work light, operating buttons, a I I 0-volt outlet, and fire fighter's requirements. LIMIT SWITCHES The present limit switches are original. They can be replaced or at a minimum be rewired and retained. It is recommended that new limit switches be provided during modernization. ACCESS SWITCHES The elevators currently do have bottom access switches. Access switches are required by current code and therefore should be upgraded during modernization of the elevators to match the manufacturer of the new car operating panel. PIT SWITCHES The pit currently does not have a conforming pit switch. Elevator code requires a new style pit switch. It is recommended that a new pit switch be provided during modernization. PIT EQUIPMENT The pit does not currently have adequate lights for code compliance. Additional lights will be added to obtain the 10 foot candles needed for safety. LED florescent are the best option to add for this parameter. The lights need to be above the 24 inches from the pit floor to avoid NEMA upgrade requirements. HOISTWAY DOOR SILLS Existing hoistway door sills can be reused. CAB The existing cab has a steel shell and canopy. Minor repairs and minor cosmetic improvements should be adequate for retaining the cabs. CAR FIXTURES The present car fixtures do meet Code requirements but not the reliability factor. The code requires replacement in order to incorporate new firefighters' requirements and ADA requirements. DETROIT P AND DC Page 13

14 We recommend the following fixtures: + New vandal resistant car station, including emergency lighting + New communications system meeting Two Way Communication requirements + Locked service cabinet + New position indicator in the car operating panel HALL STATIONS The existing hall stations do meet code but not a reliability standard. We recommend that new stations be installed. New hall station fixture plates will be engraved or embossed with "Do not use in case of fire" and pictograph, as required. Illuminated door open, door close and door stop buttons would be added at each station. Phone monitoring will be added due to code. This includes an indicator light, buzzer and text on the main egress landing hall button plate. Because the other car does not have this feature, if the cars share a line, the other car would be monitored as well.. HOISTWAY ENTRANCES The existing entrances, in which the frames support the door equipment, can be reused. HOISTWAY DOOR EOUIPMENT The hoistway doors do have the code required I 1/2hr fire label. It is recommended that the hoistway doors be retained. The door tracks and related hardware shall be replaced due to their style. MAINLINE ELECTRICAL POWER The mainline disconnect switches will be relocated. A new car light 110 volt fused disconnect and a disconnect for the oil cooler shall also be added to the machine room. FIREFIGHTERS'SERVICE The elevators require firefighters' service to meet current code requirements. Smoke sensors and related equipment for elevators were provided for the other car and need to be interfaced. FIREFIGHTERS' SERVICE SIGNS The fire recall floor pushbutton station and the new car stations are to be engraved with the proper wording for phase I firefighters' service instructions.
