SERVICES
We provide vertical transportation (VT) system design and planning services for large and complex building projects globally. We routinely work remotely from architectural concepts through construction 'shop drawings'.
We bring the leading design experience in our field to wide-rise projects, special systems, and tall buildings. Our designs are also guided by our work assisting others with existing elevators in two 'world's tallest' buildings.
ROOTS
20+ years ago we rejuvenated technical elevator consulting, upgraded for its potential. A sales background had become the norm in our field, while engineering at elevator manufacturers had become more specialized.
We provide the depth and breadth of elevator technical experience, engineering skills, and software tools needed for complex major projects, and to efficiently meet recommended elevator traffic-system design standards.
We use advanced software tools we developed to quickly find solutions for high-rise systems, provide drawings and loads to help establish elevator cores and related designs, and allow the elevator work to be 'early bid'.
Some tools are rooted in Rick Barker's paths at JB&B Consulting Engineers in the footsteps of an expert in elevator traffic, and later leading technical services at Otis and strategies for dispatching, elevatoring tools, and energy.
His work leading VT at JB&B, while serving on code committees for elevators and fire, fostered a multi-discipline appreciation, and then an aspiration to return elevator consulting to Otis to better realize its potential.
Rick became Director, Technical Services at Otis World HQ leading pre-construction services and product strategies for tall buildings globally. Still, the tools and people for an advanced technical consulting group remained a goal.
START, GROWTH
In 2000, Rick Barker and Paliath Mohandas combined their exceptional elevator experience with major manufacturers, contractors, and consulting engineers to form our company, and provide those advanced consulting services.
Several Otis R&D Engineers soon joined us: Clem Skalski, George Wisner, Paul Bennett, Mike Spaner. We expanded our tools for system design, adding others to provide building loads and some advanced analyses.
In 2010, Sean Morris joined us to strengthen our project engineering services. Sean led design services for an elevator consultancy based in Colorado, and earlier was a mechanical design engineer with Montgomery Kone in Texas.
Since, he has co-led or led system design for our tallest and most complex projects, and helped expand our tools to study elevator rope sway, power and energy, and complex traffic. Sean is now a key Principal of Barker Mohandas.
Also in 2010 we opened an office in Dubai led by Anand Sivan, an engineer who led VT consulting for WS Atkins after lift experience with Mitsubishi, Kone, Otis. He is joined by an engineer from Schindler, Sivakumar Rangaraj.
The R&D engineers who assisted us in our early days deserve recognition in helping us realize our goal, particularly our Technology Director and friend who passed away suddenly in August 2020: 'Remembering George Wisner';.
IN SHORT
We deeply understand VT traffic-system design, the cross-discipline building interfaces and codes, the history of the standards and their relavance today, elevator product engineering, and our industry's advanced technologies.
We enjoy our work. Our track record with many of the tallest and most complex projects and issues speaks for itself. Our CV's and work can be reviewed under 'Experience', and some of our software tools under 'Processes'.
