We are extremely pleased that Sean Morris joined us in 2010, where on January 1, 2013 he became a Principal who now leads or co-leads system design for many of our largest projects and tall buildings. He also continues to lead our work for vertical transportation planning drawings, engineering computations and related software applications, and special construction administration services. He has been involved with most of our building projects which began in 2010 and exceed 100 stories, such as PNB118 in Kuala Lumpur and World One in Mumbai, a very large airport, science center, various office towers including a new corporate HQ in the US, and was a major contributor to our advanced elevator engineering and system studies for the Burj Khalifa elevators.

Earlier, Sean was Design Department Manager at Lerch Bates Elevator Consulting HQ, where he was responsible for leading design services for vertical transportation projects in the USA, and several international projects. He has designed elevator, escalator, and moving walk applications under many regional USA and international codes, and worked on a wide range of projects from tall/high-rise projects such as the Trump Tower Chicago (1362ft, 415m), to airports such as the Las Vegas Terminal T3, convention centers & stadiums like the Doha Qatar Convention Center, Georgia USA Gift Mart, and Charlotte Arena, to custom elevators for the LA County Museum of Art – BCAM.


Like other key consultants in our technical team, Sean was also involved in the engineering of elevator products, in his case with Kone Montgomery where he supplied mechanical engineering designs, drawings, and materials lists for custom traction and hydraulic elevators for manufacturing and installation. In this role he also worked with architectural, structural, manufacturing, and field teams throughout the product design and installation process; and provided product and process improvements, and helped train, mentor, and check work for new engineers. This experience has been taken to a new level with us in provding solutions now followed by many manufacturers.


His advanced studies with us cover rope resonance for tall travel shuttle lifts to determine parking and opening locations, a regenerative power study for an evacuation mode to confirm advantages for emergency power, studies of drive power vs. enery consumption, and he co-authored our study of elevator safety devices going beyond current codes. Sean also holds a BS in Mechanical Engineering and is a Licensed Professional Engineer (P.E.).
