Our in-house and partner architects produce code-compliant drawings in AutoCAD , integrating ADA, Title 24, and CBC requirements from day one. You get layouts engineered for your headcount, traffic flow, and future expansion — not boilerplate floor plans.
Licensed superintendents and vetted subcontractors execute to CBC and OSHPD-adjacent standards where applicable. We run documented QA/QC checks at framing, MEP rough-in, and finishes, so structural integrity and finish quality hold up well past project closeout.
We specify low-VOC materials, high-efficiency HVAC, and LED lighting tuned to California Title 24. Where it fits the project, we pursue LEED and Energy Star strategies that lower operating costs and support tenant ESG reporting.
Design-build compresses pre-construction and construction into overlapping phases. Combined with a guaranteed-maximum-price model and weekly cost tracking, our clients typically avoid the change-order surprises that plague design-bid-build delivery.
