Find the Magic Number – Elevators Per Building

Talk about a tricky subject! Few try to tackle it in a blog because no matter what I write, there will be people that take exception. Why is this not just some simple formula with occupancy numbers, building type and square feet? Because it is more complex than that. So don’t worry I will get to rough numbers to help guide you on your project, but with a few caveats. The most important being, a qualified elevator consultant can be a huge help in this area. Consider finding the right one. Now on to the things that you should consider.

The number of elevators needed has a lot to do with many factors that may not be known when a building is in the planning stages and the first thing that gets dropped into the architect’s plans are the ways to go up and down in a building. So do your best with the list below so you can take the rough numbers I am providing and tweak them closer to your needs. Here are the things to consider:

  1. Elevator use. Just people going to work is one thing. Furniture is another. Don’t make the mistake of getting too small a unit. The weight an elevator can hold (larger loads) can change the number you may need. One for passengers one for heavy items.
  2. Who is going to be using the elevator? An elevator that just meets ADA requirements is too small for a gurney.  The DJ and caterers going to an upstairs dance hall will need more capacity and apartment complexes may need a larger/taller elevator cab.
  3. Total number of floors. That goes without saying.
  4. Total travel distance overall and between floors. You can have two floors a hundred feet apart. That would require more speed or multiple stops close together where the elevator will never reach full speed.
  5. What is a reasonable wait time? Some buildings like hotels and offices want a time as close to 25 seconds. Apartments can have a time of up to a minute. Are you willing to pay to keep that number short?
  6. Peak times of use will always slow people down. Will you be willing to foot the bill for another elevator to handle heavy traffic in mornings and evenings? Do you have peak times at all?
  7. Will there be a known traffic pattern? For instance the world’s fastest elevator only travels from the ground floor to a hotel lobby 95 stories up. It was built to accommodate a known traffic pattern.
  8. Square feet of the floors. If a building is very small, the footprint of the elevator may eat up more space than practical and the distance to walk from the elevator to an apartment will be short. In a hotel with multiple wings, many elevators may be needed.
  9. Building codes! These are more influential than most of the above. You must know what is allowed and what is required in your city, state, county or other jurisdiction.

All of the above will ultimately influence your decision making process.  Just keep in mind the point is to serve the maximum number of people with the most minimal waiting time at the highest peak times to disperse the population as fast as possible.

So with all that stuff to consider, here are rough numbers I promised. Remember to be nice when you respond to this blog. Keep in mind that these are very rough number to consider.

Office buildings:

  1. One elevator for approximately 50,000 square feet in use. For every two floors or two and a half floors consider adding one more elevator.
  2. Try not to exceed eight total elevators in a single grouping. No group should serve more than 16 or more floors.
  3. Consider a special service elevator if you are going over four floors. When you get closer to ten it is probably must logistically.
  4. Remember some floors may increase the number of elevators. A common lunchroom contained on a single floor room may force the need for another elevator due to traffic.

Hotels:

  1. Provide one elevator for every 75 rooms or so with a minimum of one elevator
    up to three floors and add one more for four floors. Don’t go past 150 feet from farthest room to elevator.
  2. As you build up and add rooms, remember to add elevators per every 75 rooms.
  3. To help room service and maid service add a service elevator for every two passenger elevators.
  4. Ballrooms, meeting rooms, or expanded lobby areas above the entry level can increase the number of elevators.

Apartments / Condos / Dormitories:

  1. There should be one elevator for every 90 units. A maximum of 150 feet from
    the elevators to the farthest elevator is a must.
  2. City apartments and really high priced units can require an elevator for every 50 – 60 units.
  3. Always have an elevator with higher ceilings (9 feet) and higher weight capacity (3500 lbs) for moving furniture and heavy items. If you are over 10 floors, a service elevator or small freight elevator should be considered.
  4. Four stories or more above grade a gurney sized elevator is required.

Medical Facilities:

  1. In buildings with consistent staff and visitor traffic, consider separate passenger elevators for staff and patients.
  2. Two elevator minimum and one for every 100 beds after that, that patients can access.
  3. Additional elevators may be required if visitors are higher depending on the location of the medical facility.
  4. Dirty elevators maybe needed. Moving medical waste sometimes requires a special elevator.
  5. Additional elevators may be required if operating areas, cafeterias, laundry, central supplies, etc. are on upper levels.

This is my personal cheat sheet based upon our research and experience. But, keep in mind that these number can and will change based upon the factors above and other variables not listed or not even thought of yet. The elevator world is still grappling with large mixed use projects that incorporate several of the above categories into one facility. So be thoughtful, ask plenty of questions and if you need the help contact us or a qualified consultant.

Awards Continue for Phoenix Modular Elevator

S-Figueroa-6Phoenix Modular Elevator was honored as an affiliate to the Award of Distinction with partner Silver Creek Industries at the annual World of Modular Conference held in Hollywood, Florida in March of this year. The World of Modular event is sponsored by the Modular Building Institute.

Awards of Distinction are the modular building industry’s premier awards program, recognizing design excellence in structures built using prefabricated systems. This is the second year in a row that Phoenix Modular Elevator has walked away with hardware as a recognition of the product and use.

The award winning project, KIPP Academy, is a three-story, 27,429 square-foot structure which houses an entire charter school campus and related functional spaces. The building contains 18 classrooms, a kitchen, multipurpose space, administrative spaces, interior corridors, and an interior elevator provided by Phoenix Modular Elevator. The building exterior features plaster with a bright color palette and aluminum glazing systems. The finished building reflects the coordinated efforts of all team members to provide a design-focused experience. Due to the complexity and scope of the project, the ability to perform the work in a factory environment provided the opportunity for significant cost reductions and increased quality control measures.

Phoenix Modular Elevator continues to win awards and accolades for elevators.

Don’t Suffer Buyer’s Remorse

Empty WalletRecently, we got an all-too-familiar email when following up on an apartment complex bid we had put together on an elevator project. We had been asked to provide a bid for a new project, and about a year had passed since the project had been awarded.  We were not the vertical transportation solution chosen. However, this type of email exchange is something that has become very common for us as the prospective customer checks their wallet at the end of the project and finds out it is empty.

In answering our question about how the project was going, the customer responded, “As you know, the contractor went with a conventional unit, which on the surface is cheaper.  However, if all the costs were included, I’m sure we picked the wrong one. Anyway, I like what you are doing and will look forward to working with you in the near future.”

He went on to say that the person in charge of accepting the bid had failed on a number of levels leaving many scratching their heads and wondering how the cost got so far out of whack. First and foremost, the cost analysis completed had not included the expense of building a stick-built hoistway. Our units, of course, include the hoistway, complete with finished doorways and hall calls ready to go, with the elevator car inserted in our factory and all of the wiring already complete. It is ready for installation, whether traction or hydraulic. The four-by-four-inch tube steel hoistway is wrapped in drywall to provide a one- or two-hour fire rating and will accept any finish, whether it is going on the interior or exterior of a building.

Pleasant Prairie

The customer was also frustrated with the constant delays of the project by the stick-built elevator company.  Starts and stops are not unusual on a big apartment complex project, but the delays coming from an elevator contractor can be maddening.  Keep in mind, the old-fashioned stick-built elevator companies will say they have a 16-week lead time, but they are not including construction of the hoistway. This means that the elevator hoistway is the first thing built and there it sits until the project has the electric turned on.  Then they start placing the rails and building an elevator car inside the hoistway (the dumbest way to build an elevator).  Weeks to months later, it is finally finished. We have an eight-week lead time and less than a week installation. One of our current clients estimates our solution can shave six months off the total construction time. Faster completion means quicker occupancy.

Third on the list of complaints was a steady stream of change orders.  When we price a project, we don’t just throw rough numbers or standard designs out there that do not match your expectations and then change-order you to death when it is not what you wanted.  We take the time to read the specifications closely and deliver a proposal as close to the final price as possible. We know this keeps us from being competitive on some jobs, but we are willing to take that chance. Knowing what you as the customer want and delivering an accurate bid are important to us, and we hope it will be for you as well.

Lastly, ongoing costs of long-term maintenance agreements drive the cost of the elevator way up when dealing with the Goliath elevator companies.  Over a 25-year span of time, maintenance for a single three-stop traction unit from a major elevator company is nearly $180,000.  Many unknowingly are inking a lopsided deal that spans the best ten years of the life of an elevator and auto-increases every year. Our elevators have non-proprietary parts that allow for flexibility and shopping of maintenance contracts. This can be a significant savings over time. Our elevators also come with a one-year initial maintenance contract that can be shopped if the customer is not satisfied with the service.

For all the above reasons, the prospective customer felt buyer’s remorse. We may have lost the first bid, but we gained a life-long customer in the process. Hopefully, you will skip the pain of overpaying and start with a modular elevator from Phoenix Modular Elevator.

Elevator Ignorance Cost Big Time

benjamin-franklin-portrait“We are all born ignorant, but one must work hard to remain stupid.” ~ Benjamin Franklin

Recently we received an inquiry from a prospective client regarding our suggested use of a hydraulic unit in a four story project with approximately forty-five feet of travel.

The client was very impressed with our eight week lead time and one week install that could simply not be matched by any stick built alternative. However, they were being sold hardcore on the notion that hydraulic elevators were too out-dated and more costly regarding electricity used over time and the initial wiring. To answer their questions and suspicions, they went to an electrical contractor for basic answers and got some really bad info.  Fortunately, they reached out to us before making a decision. Without casting aspersions, the electrician was obviously out of his depth and showed the ignorance that good ol’ Ben Franklin was warning about.

The electrician was just flat out wrong about required lighting and receptacles in the elevator pit (yes, you still need one for MRL Traction) and shaft as well as shut off requirements, but, more than that, he was quite myopic when it came to overall electric costs. His contention is found in the old canard that hydraulics are significantly more expensive to run as there are no counter-weights. Usually missing in the equation is that hydraulic units cost virtually nothing when they go down (gravity, not an electric motor, does all the work in the case of hydros when they descend). Also, electric is not the only cost in play and ultimately not that important in the overall picture.  But, don’t take my word for it.

One of the companies that pushes a traction mode-of-conveyance the most made this stunning admission in a blog post just three-years ago concerning hydraulic elevators:

Thiesen Blog“In fact, a 2,500 lb. elevator,  traveling a single floor (12 feet) at 100 fpm (feet per minute) and operates 100 runs a day,  does not even use $600 worth of energy in an entire year. So assuming the hydraulic uses more energy than traction, you could have a differential of perhaps just $150 a year in energy cost.” 

But even more shocking is what follows:

“We conducted Life Cycle Costing (LCC) research on low-rise elevators to help customers understand their economic and environmental impacts. LCC looks at the costs involved with a product or service over its entire lifetime. The study showed that over 25 years, the cost to maintain three-stop traction MRL is $173k compared to the same hydraulic MRL which cost $91k.” 

I don’t have to tell you, but that is a huge. They are admitting in basic terms that an MRL traction is, give or take, seven grand out of your pocket every year when a hydraulic is only three thousand-seven hundred. That is for the same travel distance and same number of stops. In addition, there is no increased safety in traction MRLs. So the question is: why are so many people being duped into buying something that is by-and-large identical, but costs more in the initial installation and over the life span of the unit?  Believe me, when a visitor to your building pushes the up button they will not know the difference between the two but, if they do, they will find the ride in a hydraulic to be quieter and smoother (not that we’re counting, but if you’re keeping score at home that is another two wins for hydro).

Again, this is my opinion but it is backed up by facts provided by the Journal of Applied Mechanical Engineering that put the argument between traction and hydraulic to rest in low rise applications. In the article “A Critical Review and Investigation of Machine Room Less (MRL) Elevators” the authors made the following observation: “Hydraulic elevators are more suited to small rise buildings and freight applications.” It doesn’t get more straightforward than that.

But the article goes on to explain: “This report after experimentally mapping the performance of different elevator drives under varying parameters of passenger capacity, severity of service, travel and speed finds that Hydraulic elevators have advantages over traction drives in low rise applications:

  • Substantially lower initial cost of equipment and its maintenance for a given capacity hydraulic elevator equipment cost up to 40% less than traction equipment
  • More building space utilization as the hydraulic elevator utilizes up to 12% less space than an equivalent traction elevator, as the hydraulic system imposes no load on the column the column size can be reduced
  • Effective for high load requirements such as freight elevators
  • Lowest cost down speed among all elevators as gravity is utilized as the motive force

Although the report notes advantages of MRL traction units, it concludes that they have “less seismic safety” and “increased cost of inspection and maintenance.”

CiceroTo the electrician doling out sage advice (contrary to facts) and to anyone else beguiled by the big elevator’s push for more profits in maintenance and installation, I have another quote.

“I am not ashamed to confess that I am ignorant of what I do not know” ~ Cicero

It is important that, when looking at the elevator alternatives, you do not just listen to sales pitches that will cost you significantly more in the short and long term. Take a look at the facts, determine your needs, and choose wisely.  If you need help assessing what elevator will suit you best, don’t rely on a company that profits from selling you an elevator which will also make them more money in maintenance.  As we are independent, we have no profit motive in the maintenance contract, so we can help (Yes, seriously! We typically subcontract with an independent elevator maintenance company local to you, so we don’t make any profit on the cost of maintenance, no matter what kind of unit you choose). A qualified elevator consultant can assist, as well.

We are not saying that MRL traction units are not an alternative because they are an applicable mode-of-conveyance in the right application. What we are saying is that they have a place and it is just not usually in low rise buildings.  If you have a project in mind, feel free to contact us for a quick quote and our knowledgeable team will happily advise on the most effective and beneficial mode-of-conveyance for you.

Weather Halts Construction – But Not Modular

20160105_143405We rarely re-post stuff from our other blog  Elevator Schmelevator however it seems like great info for this blog as well. Enjoy!

We have all seen the headlines: The winter weather this year, and nearly every year, puts a damper on the construction industry and new elevator installation. Work vehicles get stuck in the snow, batteries are drained dead in equipment, and materials often have a negative reaction to sub-zero temperatures. If you are having a new stick built elevator installed, it is important to know about these delays.

Concrete is one of the materials that suffers most during construction in winter weather and it’s also one of the most common ways people build hoistways or shafts. Pouring concrete is delayed anytime it gets too cold, according to Darrell Bailey from Morton Building, a firm that specializes in metal buildings of all sorts. He has seen people try to pour concrete in bad weather with horrible results. He said, “It will freeze and bust. You just can’t pour on frozen ground,” and “that means you are stuck until things thaw out.” There are some actions that can be taken to speed up the process, such as trying to warm the ground with concrete blankets or black plastic for a few days before the pour, but the results are hard to predict.

Another option is changing the mixture by adding extra concrete mix to reduce the amount of water or by adding a chemical accelerator such as calcium chloride or other heating agent. If those procedures allow for the job to continue, you still have additional work to do and several issues to work around. The area must be protected and cured for a minimum of 3 – 7 days and you can’t move anything heavy on it or put loads on it at all. You must use blankets, black plastic, or another insulating material as it cures and sometimes you’ll have to heat it from the inside and out. But there are no guarantees that these procedures will work and, if you push it too far, the surface of the concrete can freeze and pop off and it has the potential to NEVER be as durable as if it were poured in the proper temperature.

With this most recent spate of freezing temps, most of the nation’s construction came to a screeching halt. After all, you can’t even lay CMU (concrete blocks) that has either a temperature below 20°F or contains frozen moisture, visible ice, or snow on their surface. That stops a lot of building, especially elevator hoistways.

But little of this applies in the modular building industry because the bulk of the work is completed inside of a factory away from inclement weather. With modular elevators for instance we manufacture the hoistway out of tough, durable steel and then wrap it in glass-mat sheeting on the exterior and drywall on the interior for a one or two hour fire-rating.  We do not need a CMU or concrete elevator shaft to be completed. All the while it is snowing and freezing outside, the hoistway is being built inside where it is unaffected by freezing cold temperatures. As the hoistway is being constructed, the elevator components are also being manufactured in our factory or being assembled. At the end of the assembly-line you have an elevator and hoistway all in one piece, fully assembled and ready to be delivered, swung into place, and installed. The install takes less than a week and our manufacturing lead time on standard models is eight weeks plus time to ship. Keep in mind these are quality commercial elevators that are just like any other; once they are installed, they run exactly the same as any stick-built unit, but they just take a lot less time to install and they aren’t stopped by a little cold weather, snow, or ice.

The developer, building owner or designer of the project containing an old stick built elevator will just simply have to wait for the thaw to finish the job, where the modular elevator has been completed and will be in place and ready to go in a matter of weeks. Keep this in mind when you are considering a new elevator for a retrofit project or new construction.

New Year, New Growth for PME

Move to Finish 4In this past year, Phoenix Modular Elevator has made tremendous strides forward in its effort to provide an alternative to stick built elevators that is also faster and easier to install. We have moved to a brand new facility that has improved our quality and speed, with elevators flying through our production process.

We have also added more team members that do everything from welding and drywall to improving the manufacturing process. As a result, we remain the fastest installing commercial, quality elevator available, with the shortest lead time (eight weeks if it’s standard). Due to our unique design of the hoistway and elevator components all in one, there is no better way to have a quality elevator installed in any construction project.

But we are not satisfied with standing still. Our goal for 2017 was an ambitious 40% growth over 2016 and we have surpassed that goal. But reaching that goal did not come easy. We knew we had to be able to have the space to manufacture elevators that to go well above fifteen stories and to be able to produce elevators in larger and larger numbers simultaneously for jobs that need dozens of elevators, not just one at a time.  That is why the new facility was a must. It allowed us continued growth by providing the space we needed and a production line that was more efficient than the old factory location.  Now all of the production is on one floor with a much smoother work flow.

For 2018, we are again projecting 40% growth and to help push us further down the road, we again are building new space and adding an additional concrete apron around the facility to make dropping off materials and components easier, more efficient, and faster.

The new building will be constructed and operational by March of 2018 and will house our maintenance team. They are the folks that keep all of the machinery of the factory up and running. The site will be complete with a repair bay for the fork trucks and other large equipment. This will greatly diminish down time, thus improving productivity. It will also give us the space we need to develop and maintain more production equipment.  We have great ideas to improve our methods and now we will have the space to make them a reality.

Lastly, we have plans to expand the line even further. We have not broken ground yet, but plans are on the drawing board! This is a very exciting time for Phoenix Modular Elevator and we are looking forward to a happy New Year indeed. We hope your’s is just as prosperous.

Factory Built Elevator- Early Planning Makes for Easier Planning

MBI WOM 2There is no doubt that modular elevators are the future for almost any building application, from modular buildings to traditional projects and from low to medium rise and beyond. Everyone knows that modular elevators are simply safer, faster, and smarter.

But they are also easier for everyone involved in the process. Designers, architects, builders, and elevator installers are all helped by the overall concept and tremendous flexibility provided with modular.  However, there is one thing you can do in the earliest phases of construction that can make converting to the modular solution even easier:  consider a modular elevator solution as early in the process as possible.

This is not to say that you can’t consider modular at anytime during the project from design to completion. You can certainly decide on modular late in the game and we are more than willing to help.  We have even been asked to provide a modular elevator solution after a building has been completed. The customer simply got tired of waiting for the stick-built elevator company to show up and get the job done. Turns out, in most cases we can design, engineer, manufacture, ship, and install a quality commercial elevator in less time than a traditional elevator company orders and receives all its components.

However, we would be fibbing if we didn’t tell you that it is just easier overall if you begin the project with modular in mind. The reason lies in the biggest benefit of a modular elevator: that it comes with the completed, manufactured hoistway as part of the package. There is no need to design and engineer CMU walls. Our modular elevator will come with its own specially-engineered, structurally sound 4X4 inch tube steel frame and is clad in one- or two-hour fire rated enclosure.  The structure can also accommodate any hurricane or earthquake zone.  And it can support some gravity loads such as floor joists or stair landings.  So it makes a lot of sense and saves a bit of money to just draw in a hole and leave the engineering to us.

In addition, our standard wall assembly is not as thick as a CMU shaft, so using our footprint in planning will free up a few inches of space to incorporate into the rest of your building.  Our equipment may have a slightly different layout than another manufacturer’s, so it makes sense to decide up front and avoid more design modifications down the road.

Wondering what a modular elevator is?  It’s a prefabricated shaft with the elevator car and other components assembled inside the shaft in our factory.  You can read more about them here.

We can also deliver a “naked” elevator with no drywall wrapping at all. These are used for glass elevators or ones that come with decorative metal hoistways usually for an atrium or mezzanine. This flexibility means that modular elevators can be an early part of the design process.

Many buildings have a clear and intentional look and feel.  A modular elevator is manufactured in a such a way that any cab interior or hoistway finish that would be specified in a stick-built elevator can be utilized in a modular elevator.  So whether you’re looking for durable or high-end, modern or traditional, a modular elevator can deliver it cost-effectively.

To keep the process simple and to give you the ability to put a modular solution in quickly, we provide CAD drawings that can be placed directly in your schematics.

So, when it comes to choosing the next elevator for an upcoming project, call us anytime.  But think about placing the elevator early, for best time-saving results. Click below to get a quick quote if you have a project in mind or call us for a formal quote.

Pour the Perfect Modular Pit Easily

Anchor Bolts Level NutsOne of the biggest concerns that customers have is regarding the pit. Every elevator needs one, including your new modular elevator. You want to make sure you do everything right for when the elevator arrives, and this article will give you some tips to make it easy. By taking some time now, you can avoid issues and problems down the road.

On the surface, it seems easy enough.  Dig and pour a concrete pit for the hoistway, with cast-in-place anchor bolts in the corners. But, when you mix in the need to engineer the pit foundation and add reinforcements based on the elevator’s pit reactions, all the while accounting for the job site’s soil conditions and your local code requirements, it can seem more daunting. Keep in mind though, we supply the necessary information, plans, and even a template (if requested) to help out.

So, to put everyone’s mind at ease, let’s cover the basics on not only the pit but also the foundation for the modular machine room, if your project is going that route. You can also find this info on our website for easier access later.

  1. Typical pits have 8” thick walls and 12” thick floors. However, always consult your pit layout drawings for precise measurements for your specific job.
  2. If you have a sump hole, cover it with a non-combustible material, typically a sheet of metal.
  3. Pour a concrete slab for the modular machine room, if ordered. Purchase epoxy anchors to bolt it to the foundation after it is set. If the machine room is not adjacent to the hoistway, piping and electrical must be run underground or overhead. Coordinate with PME and the installer to determine any building preparations needed to accommodate this.
  4. Once the pit has been poured and the anchor bolts are in place download this Pit Drawing Form. Fill out all the blanks with exact measurements and make sure to include the project name at the top. Email the form to us. With this completed form the holes on our hoistway for the anchors will be as accurate as possible.

More detail and tips include the following:

Picture8Pit Depth – You only want to pour the pit once so, pay close attention to these instructions. The pit should be exactly 4’ deep, measured from top of finished floor to pit floor. Our tower’s legs are 3’11” long, made to sit an inch off the pit floor, with grout underneath. This allows for some adjustment if the pit floor isn’t perfect. The adjustments are done by putting a ¾” thick leveling nut and washer on the anchor bolts before lowering the tower down. Adjust the nuts as needed to plumb and level the tower. Install washers and nuts on top of the tower base plates and tighten. Grout below the base plates.

What do you do if the pit is too deep? The base plates can sit more than 1” off the floor, but if the anchor bolts are too short as a result of the extra depth, extra in-field welding will be required to produce a stable connection.

Err on the long side on the anchor bolts. They should protrude a minimum of 3.5” from the pit floor, but making them a few inches longer poses no problem with installation and gives you breathing room if the pit is too deep.

(On the other end of the spectrum) Pit too shallow: If minor, this could require grinding away a bit of concrete around the anchor bolt. If major, the pit might have to be re-poured. Avoid this at all costs! Too deep is better than too shallow!

Pit.jpgLength and Width – The pit should be the out-to-out steel dimensions plus 1” on all sides for clearance when sliding the tower into the pit. Note that the enclosure of the elevator shaft stops at the top of the pit. If needed or wanted, for above-ground pits, we can extend that enclosure down further. If the pit is too big, it’s not a big deal. However, you’ll need to make sure it’s properly flashed to keep out water and fire caulked to maintain the fire resistance of the hoistway.

Pit too small: Oops, you’re going to have to tear out some concrete. No easy fix for that.

Wall protuberances – The tower slides in right along the walls on its way to the pit floor, so it will catch on any protrusions. Once it’s set, there are openings in the structural framing that piping can be run through. Before lowering the elevator, terminate any penetrations such as PVC liner or piping at the pit wall. Run any piping/electrical after the tower is set. Note that the diagonal rods are for stabilization while uprighting the tower and may be removed after bolting the tower down, if they’re in the way.

Sump hole in corner – The base plates sit in the 4 corners and need a solid surface to rest on. If your pit has a sump hole, make sure it’s at least 12” from any corner.

Pit 2Anchor Bolts – When you pour the pit, anchor bolt placement is very important for elevator installation as this directly effects where the modular elevator will be placed. Please make sure the distance of the bolts from building is right and make sure to include the building finishes when calculating where to place the “front” anchor bolts. Too far away can be bridged with flooring, drywall, and flashing. Too close means reworking of the anchorage.

Check Please – Check, check and check again! Measure three times. Check your prints twice. Cross square them. This is critical. Incorrect placement may require torching out the base plate holes, moving anchors, or other work to provide alternative anchorage. If you know in advance that the placement is slightly off, we can widen the base plate holes in the factory, which is easier than doing it in the field. We can also supply an anchor bolt template to make bolt placement a little easier and more accurate.

Other Pit Info – If the lowest stop is above grade, alternative construction can be used for the pit. The pit floor can be poured as a slab and then walled in afterwards with CMU. Also, the elevator shaft can be finished down to the pit level to provide the pit “walls.” Note that you should at least have a short stem wall to keep water out of the pit area.

Lastly, we want this to be a success for you. If you have any questions at all, contact our team. Our engineer, Tim House, is always ready and willing to help.

A Blank Canvas – The Architect’s Dream

nypl.digitalcollections.b3afd5e1-27a1-4acf-e040-e00a180661f0.001.wArchitects often see setbacks worthy of quitting when trying to integrate the restrictions and requirements of GC’s into their artistic design.

One of history’s most important artists could have also let setbacks and failures crush him as a young painter. Giving up would have been more than understandable, as Paul Cézanne’s father saw no future in the world of art for his son and, ultimately, was instrumental in pushing his young son to study law and work in the bank he had founded instead of following his heart.

Further disappointment followed when Cézanne finally applied to enroll in the École des Beaux-Arts in Paris (one of the most prestigious schools) and he was rejected almost immediately. Likewise, in the various salons in Paris, time and again his work was refused. A lesser man’s dreams would have been extinguished and one could only imagine the pressure and anxiety that accompanied every stroke of the brush.  It’s no wonder he was quoted as saying, “It’s so fine and yet so terrible to stand in front of a blank canvas.”

The blank canvas to Cézanne was equally torture and pleasure, but none can dispute the energy he drew from it. It led to him being one of the most influential artists of his time. He was drawn to the blank canvas, simultaneously pushed and pursued by it.

In the “mother art” (architecture – according to Frank Lloyd Wright), architects too are drawn to the blank canvas. Read the rest of the article here!

Hotels + Modular = The Perfect Solution

Red Roof InnHotels built prior to the Americans with Disabilities Act (ADA) have a decided disadvantage when meeting the needs of potential customers. With only stairs to transport guests to upper floors, people with some disabilities have limited choice of the rooms they can occupy. It also means that people who do not want to carry luggage up a flight of stairs may seek other accommodations.

This issue  will likely grow. With the graying of America, the number of disabled persons will continue to increase from the 57 million current reported by the US Census Bureau. That is a whole lot of people that a hotel without an elevator may not be serving well, or at all.

Since the passage of the ADA in 1990, it has become an expectation that access will be provided. However, many older hotels are not accessible beyond the first floor, and although it is perfectly legal for older hotels to be grandfathered in and avoid ADA requirements, it may not make for the best customer experience. This can also lead to a lower rate per room for higher floors. To combat this problem, one hotelier was able to meet his patrons needs by placing a modular elevator on the exterior of the existing structure.

An ancillary benefit of the modular elevator addition is that employees were no longer lugging heavy laundry carts and other items up and down stairs. The elevator increased staff productivity and morale while also reducing the potential for work-related accidents and injuries. It was a win for the hotel, not only because it opened new possibilities for customer and employees, but because the installation was easy and fast.

For a commercial-quality modular solution, another benefit is time. A hotel does not have to close its doors for an extended period of time during installation, as a modular elevator is lowered into place by a crane in under half a day, and installation can be completed in a week.

The end result is a more profitable, safer hotel that provided access to more potential customers and a way for workers to be more efficient and productive.
