Barker Mohandas


We provide a wide range of vertical transportation (VT) consulting services covering the design of new systems, special equipment evaluations, large-scale modernization planning, and special design and engineering services. See our Projects for better insights into our services for a wide range of engagements.


A. New Systems

Our predominant work is the design of new vertical transportation (VT) systems, where for high-rise buidlings services should begin at Concept Design.


Our tools described under Processes enable us to expedite detailed designs to an "early" bidding or tendering stage, most often working remotely.


We typically follow with services to review bids or tenders, later project submittals, and observations of completed elevator/lift work at milestone times.


B. Existing Systems

We have been involved in a wide range of services for existing elevators/lifts, including for those in the current world's tallest building, and a past world's tallest.


Our master engineering tool is used to analyze equipment issues, improvements, and data recorded and observed. Other tools are used to analyze traffic performance.


We do not, however, offer routine services to manage elevator/lift maintenance, or to provide independent safety inspections under various local and national codes.

C. Special Designs & Engineering

Special design and engineering services have increased recently to examine issues in existing tall buildings, and provide a "second opinion" on design.


We have also assisted the engineering departments of major manufacturers with "as-built" issues.


The work is rewarding to help resolve issues, and reaffirm or ehance our designs for new systems, including with the realities of building operations and processes and skills being employed today in various locales.
