Existing-building evaluation
Review available drawings, building conditions, and proposed changes to establish structural design requirements and identify information needed for the work.
California structural engineering
Structural engineering for commercial, residential, and existing buildings
Vexo helps owners, architects, and project teams evaluate structural conditions, design building alterations, and support new equipment. We prepare structural drawings and calculations for commercial, multifamily, select single-family, industrial, and other suitable projects across California.
What the service covers
What we can help with
Structural design and calculations
Develop framing, alteration, and strengthening designs supported by project-specific calculations and details. Coordinate structural documents with the architectural plans and other disciplines.
Equipment support and anchorage
Design supports and anchorage for rooftop, suspended, and floor-mounted equipment. Review equipment loads and how they transfer into the building structure.
Permit and construction questions
Prepare structural documents for permit review and respond to plan-check comments within the original scope. Responses to standard construction requests for information (RFIs) are provided when included in the agreed scope.

Common questions
Before you get started
Can you evaluate a roof or floor for new equipment?
Yes. The scope can include reviewing proposed equipment loads, available structural information, and requirements for supports or anchorage. The review helps establish whether additional information or structural design is needed.
What if the existing drawings are incomplete?
Share the records you have. We review the available information and identify additional inputs or investigation needed to define the engineering scope.
Can structural work be coordinated with our architect and MEP team?
Yes. Equipment locations, openings, routing, and supports often require input from several disciplines. We define the coordination responsibilities as part of the engagement.
How are the scope and engineering schedule established?
They depend on the proposed work, available information, required deliverables, and coordination needs. Share your target dates with the initial inquiry so those requirements can be considered.
