California building-systems engineering

Mechanical, electrical, and plumbing engineering for building projects

Vexo develops building-system designs for commercial, multifamily, select single-family, industrial, and existing-building projects across California. The scope can address an individual discipline or coordinate mechanical, electrical, and plumbing work with your architectural plans, equipment, and structural requirements.

What the service covers

What we can help with

Mechanical and HVAC

Develop heating, cooling, and ventilation designs around the building’s use and operating needs. Coordinate equipment selection, distribution, and related calculations within the agreed scope.

Electrical systems

Develop power, lighting, and equipment-connection designs based on project loads and available system information. Coordinate layouts, schedules, and related electrical documentation.

Plumbing and utilities

Develop water, waste, vent, and gas system designs for the proposed work. Coordinate fixture requirements and utility connections with the building layout and existing systems.

Coordination across disciplines

Coordinate equipment locations, routing, service access, and structural supports. Review these relationships with the project team to help identify conflicts before installation.

Project fit

Projects we support

Commercial tenant improvements
Multifamily and mixed-use buildings
Select single-family projects

Building-system upgrades

Engineering scope

Typical deliverables

Depending on the selected disciplines and agreed scope: plans, equipment schedules, calculations, details, and coordinated permit documents.

Initial review

What to share first

  • Building use and operationsOccupancy, operating needs, and known system limitations.
  • Layouts and equipmentProposed plans, equipment requirements, utility information, and available drawings.
  • Scope and coordinationRequired disciplines, project-team responsibilities, deliverables, and target schedule.

Common questions

Before you get started

Can the scope cover one discipline rather than all three?

Yes. The proposal identifies the mechanical, electrical, or plumbing services needed for the project. Where several disciplines are involved, it also defines their coordination responsibilities.

What information helps you review existing system capacity?

Available drawings, equipment schedules, load information, and utility records help establish the starting point. We identify additional inputs needed for the requested engineering work.

Can you coordinate new equipment with structural engineering?

Yes. Equipment loads, openings, supports, and anchorage can be coordinated with the structural scope, alongside power, plumbing, ventilation, and access requirements.

Does the scope include permit-review responses?

The proposal identifies the permit documents and review support included. Responses address comments within the agreed engineering scope; changes to the project or additional systems may require a revised scope.
