Elevator Job Site Hall of Fame – Class of 2019[1st ½ of year]


Please find the class of 2019 elevator job site hall of fame photos from the first ½ of the year.  As we go through the bidding process we pluck photos to go in our "hall of fame" of elevators we will never forget.

I call this one 14 buckets.  I went into a machine room to give a building a price on an elevator cylinder and saw this.  14 buckets and a 55 gallon drum.  While alarming that a building would have 14 empty 5 gallon buckets and a 55 gallon drum, it was almost more alarming to me when I looked at the label on some of the buckets that they were sent by FedEx. Who FedExs hydraulic fluid?

When I was in Scotland I visited something called the “Disgrace of Scotland” in Edinborough.  The Scots started building a monument designed after the Parthenon, but, they ran out of money.  This controller should be called “Disgrace of the Elevator Industry”.  A building owner paid good money for an elevator controller and this is what they got. 

I got a text from a mechanic I work with and I thought he was kidding. 

This could be done better.

I’m not sure what happened here.  We know where the oil leak monitor will be and we know how much conduit we will need.   We also should know the extent that we can use Greenfield.

We do a lot of hydraulic piping and I know all situations are not perfect and have challenges, but…

180 degrees of additional resistance in the line that is unnecessary.

Once upon a time we engineered projects from our desk.  We don’t engineer projects from our desk anymore.  This equipment replacement was engineered from someone’s desk.


Could this be Dexter or Patrick Bateman’s elevator or this elevator is going to the Blueman Group or Gwar and sitting in the front row?

A17.1 2016 Elevator Code – Hoistway Access


Prior to the 2016 A17.1 code we would see hoistway access in many different places; hall stations, door frames top, door frames bottom, next to elevator, etc.  The code committee change this with the 2016 of the elevator code for new construction or modernization.  There are strict requirements for location per 2.12.7.2.1.  Important that everyone that has moved or will be moving towards the adoption understands.  The City of Chicago is on 2016 code.  The State of Illinois is on 2013 currently but will be on 2016 after adoption takes place... oi



1.    48” to 72” above floor measured to the centerline of the switch
2.    On the wall outside of the hoistway within 12” of the entrance frame
3.    On the hoistway entrance frame or jamb
4.    On the sight guard
           
Here are a few examples of what will work and what will not work

[This access station is not 48" above AFF - No Good]

[This Hall station is within 12" of frame but when we ordered it we had to extend the height to accommodate the 48" to 72"]

[This access station is more than 12" from both door frames - No good for A17.1 2016]

Take away – While this isn’t a huge deal for any modernization or new construction, it does force us to pay a little more attention to the design of our fixtures.  If you do not pay attention to the code change it will cost a little bit to comply and you will have frustrated elevator field personnel.

State of Illinois Elevators – Elevator Braille mandate


We have another mandate in the State of Illinois for elevators, this time it is Braille.  Please read below.  Our two largest inspection agencies are writing up buildings.  To date most inspectors are writing "by next visit".  Here are what the expectations are.

a.    New elevators for which building permits are issue after the effective date of this Act or October 1, 1977, whichever date is later – immediately
b.    Existing elevators undergoing renovations of the control panel for which building permits are issued after the effective date of this Act or October 1, 1977.  Whichever date is later – Immediately;
c.    Existing elevators no undergoing renovation, the ealier of:
1.    90 days after the effective date of the Federal standards governing elevator control markings applicable to privately owned buildings, or
2.    June 30, 1980
 Braille requirements

Hoistway entrances – 4.10.5 – All elevator hoistway entrances shall have raised and Braille floor designations provided on both jambs.  The centerline of the characters shall be 60 in above finish floor.  Such characters shall be 2” high and shall comply with 4.30.4.  Permanently applied plates are acceptable if they are permanently fixed to the jambs.

Car controls – Tactile, Braille, and visual control indicators.  All control buttons shall be designate by Braille and by raised standard alphabet characters for letters, Arabic characters for numerals, or standard symbols as shown by Fig 23a, and as required by ASME A17.1.  Raised and Braille characters and symbols shall comply with 4.30.  The call button for the main entry floor shall be designated by a raised star at the left of the floor designation.  All raised designations for control buttons shall be placed immediately to the left of the button to which they apply.  Applied plates, permanently attached, are an acceptable means to provided raised control designations.  Car control Braille shall be 16mm on the symbol with with a 4.8mm space then Braille below.

Take away – Put your Braille up.  The Braille isn’t expensive and it is a good idea in general to make a building more accessible per ADA rules.  There are certain requirements for size and composition of elevator Braille.  For more information on this contact your elevator contractor.

Chicago elevators in the news


About once a year we would see a network do a feature on elevators in the Chicago area.  Over the last 2 months we have had 3 features by 3 different network news.    It is always interesting how the news portrays our industry and sides of the stories.  Take a look at each feature, they are interesting.


The first feature is a good one about ages of elevators and the requirements to maintain them and replace equipment.  John Valone of IUEC Local #2 did a great job working with WGN on this one.  I have this conversation with building owners frequently, If your elevator is over 30 years old your reliability expectations should be adjusted and building’s should be planning on equipment replacement.



The second feature is about an incident at the Hancock building that occurred a few months ago.  Everyone involved in the interviews appeared to be knowledgeable and well informed.  Good to see.



The third feature is about a building next door to a building we are modernizing that had their elevator shut down for 4-5 months.  The interesting part of the whole feature is that this is a condominium, the people interviewed own the building but do not know what is going on, which is concerning.  We actually bid this project and the building paid 20%-30% to work with another firm and the project is just now being completed.  This is a 6 story building that was with out an elevator for 4-5 months.  That is also concerning.


All three segments where well done and interesting to see our industry in the news.

Elevator shunt trip disconnecting means


The requirements for elevator electrical “work by others” is a fairly simple scope but many times it is confusing for the electrician because they do not do this type of work on a regular basis. Recently we have been getting a lot of questions of how or when a shunt trip should be installed.

1.    A shunt trip shall be installed if there are heat detectors
2.    A heat detector shall be installed if there are sprinklers
3.    A smoke detector shall be installed if there is a heat detector
4.    A heat detector shall trip the breaker disconnecting the power from the elevator machine room.
5.    A shunt trip device does not necessarily need to be in the elevator machine room
6.    The shunt trip needs to be monitored by the fire panel
7.    The fire recall detector provider and electrician need to work together for heat detector/shunt installation
8.  There is an elevator control feature where the heat is wired to the elevator controller and it will let the car down on FEO prior to shunting the disconnect.  We do not want to trap people when the car is shunted.  This is not a popular feature yet but may gain traction.


[Sprinkler & heat = shunt]

[Shunt/disconnect in one]

[Shunt and disconnect separate]

Importance of elevator data tags


When we are doing elevator modernization there is a very large reliance on the existing elevator data tags.  It is important that we pay attention to these tags as they are most likely the only piece of information that is left to help us understand the original engineering as most of the final engineering documents from construction are long gone.  When we do not pay attention to the data tags or the data tags are gone, or someone else in the past hasn’t paid attention to the tags it can provide challenges when engineering or installing the elevator system with assumed information.

Issue #1 – We were awarded a modernization project at a municipal building and when it got to engineering, we found this on top the elevator. 



Significance – Low

Outcome – All the information was cross referenced but whomever the knucklehead who painted over the data tag should get a dunce cap.

Issue #2 - The biggest issue we ran into recently was when one vendor replaced a motor when they changed the controller.  Another vendor replaced a machine less motor but did not check the motor that was installed to see if it was correct.  Another vendor replaced the controller again years later with a machine that matched the crosshead data tag but the motor that was installed with the first modernization was not engineered correctly.  In this situation we have these nice new flexible drives that could be challenging to work with in this scenario.  By the time we realized what had occurred it was too late.  What should have taken place was to take car speed measurements prior to engineering.  The car said it went 100fpm, it seemed like it went 100fpm.  It really went 75-80fpm with the existing motor.  The engineering data went to the control manufacturer and popped out a motor to match the old motor.




Significance – High

Outcome – We worked this out and made the corrections and the building go their 100fpm car but this was after mystery, headaches and a lot of wasted time.

Issue #3 – We went out to engineer a modernization project and found this.  Painted then someone had attempted to scratch off the paint to find that nothing was ever etched or stamped into the data tag.



Significance – Low - Medium

Outcome – This was a US Elevator and we have modernized many of them so we have a lot of data on similar elevators.  There was no issue here but could been if the car weight was abnormal or we didn’t check the car speed.

Take away – We as elevator professionals should be leaving the correct data on projects for the next person.  If we do not have the correct data we should be getting identification that is permanently marked so it will forever be with that piece of equipment.

Traction elevator control modernization – Chicago, IL – Historic building


We had the opportunity to work at the historic South Shore Cultural Center at 7059 S. Shore – Chicago, IL for the Chicago Park District.  The building was built in 1905 and a theatre was added in 1909.  In 1916 the building was redesigned in the Mediterranean Revival style. This is the building that still stands there today.  Originally it was built as a Protestant only club, later, Irish Catholics were admitted.  Besides the main clubhouse the South Shore Country Club also had stables, 9 hole golf course, tennis courts, a bowling green and a private beach on Lake Michigan.  The once private club was sold to the Chicago Park District in 1975 as the club was forced to liquidate its assets.  Today the Cultural Center is fully integrated into the neighborhood and houses a School for the Arts, Theater, Fine Arts Gallery, two dance studios, music practice rooms, visual arts studio with a kiln.  There are facilities for weddings, receptions and meetings.  The golf course is still in operation, as is the beach, picnic areas, gardens and nature center.  The horse stables are used by the Chicago Police Department’s mounted unit.  It is a really cool beautiful old facility with a wonderful state of the art kitchen for events.

This project has been on our radar for a number of years and finally it got legs about a year ago.  It was an interesting project in that the control area was being moved from being by the machine at the top level to the 2nd landing.  The building had been plagued with water issues on the lower landing so it was challenging to work with the older building structure, shallow pit and water.


Material providers

Control system – MCE
Motor drive - KEB
Fixtures – Innovation
Cab – H & B
Door equipment – GAL
Buffers – OLEO
Roller guides - ELSCO
Door protection - Adams Gatekeeper 3000

Elevator interior - The elevator interior was interesting.  This most likely was a manual elevator at one time and looked like it had been modernized a few times.  We had a two speed door on the car with single speed doors on the hatch.  The dimensions of the elevator front was atypical which made it a more challenging to engineer correctly with the position of the hatch frames compared with a typical elevator cab.  The cab was provided H & B from Minneapolis, MN.

 Before 

  After 

Elevator control system - The elevator control system at one time was next to the elevator machine which had limited space and electrical clearance issues.  Not sure how many times the controller had been changed prior to this modernization but the new controller was outside the machine area in a general mechanical area with height restrictions from duct work and outside the sight line of the machine.  The control system was moved from the 7th floor to the 2nd floor in its own control room.  The control system provider was Motion Control Engineering.

 Before

 After  

Elevator machine - The elevator machine room was in a penthouse that was very small.  The machine and motor appears to have been changed in the late 1980's and perhaps the motor changed to AC when the last control system was replaced.  Machine was retained, motor retained.  The machine is a Hollister Whitney OH53 in good condition.  We put some covers on and gave it a new coat of paint.

 Before

 After 

Elevator fixtures/push buttons - The previous COP was on the strike side of the jamb.  Since this was such a odd interior layout with the hatch doors we moved it to the return side and used Innovation Industries.  Lots of unique building requirements to work with and Innovation was great with all of our back and forth changes. 


  Before

After 

Elevator car top/door operator - The entire car top had to be reworked as we got a new cab.  Over time the car top was exposed to the elements and everything that goes along with a 100+ year old building.  GAL door equipment and Ktech load weighing was installed here.
 Before

 Before

After 

Elevator lobby set up - The building had some interesting architecture which included angled door frames.  Part of the challenge here was to minimize adding too many extra holes in the frames as they where going to be retained and didn't want plates on them.  With the new requirement of emergency communication failure we came up with a creative way to comply with the new code requirements and reduce the utilize the existing holes in the door frames. In Chicago we are required to put the FEO phase I in the top left side of the door frame.

  Before

 After 

Elevator pit - This was the most concerning issue for the building water in a shallow pit.  The building is located steps away from Lake Michigan and had a shallow pit that constantly was getting water it it.  We worked with the design team on a very shall sump hole, a deeper one could not be dug due to footings.  We had an issue with the specified buffers so we went with a lower profile buffer made by OLEO.  At first the OLEO buffer seemed like a toy compared to the more robust Hollister Buffer we are used to but during testing they held up and allowed us to get the under travel we needed.

 Before

 After 


It was a great project to work on, a lot of work on the front end and a lot of hard work on the execution by the installers. Working in older buildings always is a challenge because the existing conditions challenge you to think outside the box for material provider solutions.  New elevator equipment is designed for today's conditions, not conditions of elevators installed 100 years ago. All together 14 people from Colley Elevator played a roll on the project from the bid to the consultant walk through.  Not only is it the sales person and the installation team but everyone in between that does engineering, delivery, certified payroll, billing, etc.  A true team effort here!  Thank you to everyone on team Colley and our material providers for so much help to make this project a success!
