California structural engineering
Structural evaluation and design for building alterations, equipment installations, and existing-building upgrades. Vexo prepares drawings and calculations for commercial, multifamily, select single-family, industrial, and other suitable projects across California.
What the service covers
Evaluation of existing structures for proposed alterations and equipment installations. We review available drawings and building information to establish design requirements and identify gaps that need further investigation.
Framing, alteration, and strengthening designs supported by project-specific calculations and details. Our structural documents are coordinated with architectural plans and other engineering disciplines.
Support and anchorage design for rooftop, suspended, and floor-mounted equipment, including the transfer of equipment loads into the building structure.
Structural drawings and calculations for permit review, with responses to plan-check comments within the original scope. Standard construction requests for information (RFIs) are addressed when included in the agreed scope.
Project experience
Selected projects, with engineering scope and excerpts from the design drawings.
Piping isometric and supports
San Leandro, CA
Structural, mechanical & piping
Structural, mechanical, and piping engineering for an oil-immersion tank system in an existing industrial facility. The work covered structural and seismic verification of the supplied tank, equipment and crane foundations, and an exterior aboveground storage tank (AST) pad with containment walls. Mechanical and piping design included ventilation, oil and water piping analysis, and pipe supports.
Fremont, CA
Structural & MEP
Structural and MEP engineering for five three-story townhomes above an underground parking garage. The design covered residential framing, garage ventilation, electrical power and lighting, and water and drainage systems for the homes and shared parking level.
Oakland, CA
Structural engineering & seismic retrofit
Structural engineering for a basement conversion and seismic retrofit in an existing 10-unit multifamily building. The proposed conversion added two basement residences, with new footings, posts, and steel shear-wall panels supporting the alterations and strengthening the garage openings.
Oakland, CA
Structural engineering
Structural design for a first-floor remodel in an existing multifamily building. New concrete footings, wood posts, and engineered-lumber beams supported the revised layout while retaining the existing floor framing. The drawings also detailed shear walls, hold-downs, and connections to the foundations.
Oakland, CA
Structural engineering
Structural strengthening at the garage level of an existing multifamily building. The design added concrete footings, wood shear walls, and prefabricated steel shear-wall elements, with connections to the retained floor joists, beams, and posts.
Menlo Park, CA
Structural engineering
Structural engineering for a custom home with a second floor and roof areas at different elevations. The design included foundations, floor and roof framing, shear walls, and the connections supporting the architectural layout.
Sunnyvale, CA
Structural engineering
Structural engineering for a new two-story custom home and detached accessory dwelling unit. The drawings covered foundations, engineered wood framing, and seismic connections for both buildings, including framing and connections around the main home’s stair opening.
Selected drawing excerpts are shown for project context, not for construction use.
Project fit
Specialty service
Seismic evaluation, retrofit design, and permit support for multifamily and other suitable existing buildings with identified earthquake vulnerabilities, including select single-family projects.

Initial review
Common questions
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.
Share the records you have. We review the available information and identify additional inputs or investigation needed to define the engineering scope.
Yes. Equipment locations, openings, routing, and supports often require input from several disciplines. We define the coordination responsibilities as part of the engagement.
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.
Project inquiry
Share the project location, services you need, and a short description of the work.
