Elevator Engineering

RCB Elevator Consulting, LLC (RCB) is a full service elevator design & engineering firm.  Unlike most elevator consultants who provide services to building owners and architects, RCB provides services exclusively to elevator companies.  Though we are frequently involved with new construction projects, the greater portion of our work is in conjunction with the modernization of existing, older elevator systems. 

RCB provides elevator submittal shop drawing preparation and structural engineering services.  This service is especially suited to laying out more complicated major alterations, especially those involving structural changes and where there are seismic considerations.  The drawings and engineering produced are suited for owner, consultant and jurisdiction submission & approval; are instrumental in ordering and fabricating equipment; and are essential for proper field installation.  Drawings are typically detailed down to the component fabrication level for non-standard vendor products.

Although located in Sonoma, California, we perform services nationally.  Design engineering for the modernization/alteration of existing elevator systems typically require a proper and thorough field survey.  We have found that to prepare the engineering for most projects, it is best that we perform our own comprehensive field surveys. 

Feel free to have a look at a few samples of elevator engineering projects on our Elevator Modernization Projects page.

If you are an elevator company in need of elevator engineering or shop drawing preparation, give us a call.  Think of us as your elevator engineering department.

Elevator Modernization & Alteration Engineering
Submittal & Installation Layout Shop Drawings
Field Surveys
Elevator Structural Engineering - California License
