Facility 252492-G22

1401 Fort Street

Detroit, Michigan 48233-9706

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, 18th,

2016. 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 1992.

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

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 1,2 ------------------------- $ 18,000.00 ea x 2 = $ 36,000.00

Freights 3, 4 ------------------------ $ 18,000.00 ea x 2 = $ 36,000.00

Freights 15A, 16B ----------------- $ 18,000.00 ea x 2 = $ 36,000.00

Total $ 108,000.00

DETROIT P AND DC

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.

OPTION THREE

The best option is for replacement of all of the equipment under one contract. 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.

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

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

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

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.

The motor will be upgraded to a VVVF unit to enhance energy savings.

CAR DOOR EQUIPMENT

The existing Courion door equipment should be replaced with similar or better door equipment.

Many of the hoistway door panels are damaged and warrant replacement. 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.

DETROIT P AND DC

MACHINE ROOM

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 but not accessible from the entrance. The

car top run station must be relocated or a stop switch mounted on the front side of the car top to

secure the car prior to getting on it. The new station should include a work light, operating

buttons, a 110-volt outlet, and fire fighter's requirements. It is to be located at a convenient

location on top of the crosshead. Additional stop switches shall be added to secure the car from

the entrance.

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

manufacturers style of the new fixtures.

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 truckable sills can be reused and those with damage or are loose shall be

repaired and secured.

CAB

DETROIT P AND DC

The existing cab has a steel shell and canopy. Minor repairs and painting should be adequate for

retaining the cabs. Several cabs need the side walls pulled in and a new bumper rail installed

to limit future damage. All wooden flooring is damaged and warrants replacement or covered

with aluminum deckplates.

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.

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 replaced due to the damage and wear. The door tracks, locks and related

hardware shall be replaced due to their wear and damage.

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.
