Our Capabilities
Engineering & Design-Build
Design-build civil engineering and CAD support, from site schematics and surveying to as-builts.
From Planning to Field Execution
For more than 50 years, Lewis & Tibbitts has helped public agencies, utilities, contractors, and private clients navigate complex infrastructure projects throughout Northern California.
By combining construction experience with engineering and preconstruction capabilities, L&T can identify challenges early, coordinate with project stakeholders, and develop practical solutions with constructability in mind. From design review and CAD development to permitting, scheduling, and construction, the goal is a more coordinated path from concept to completion.
Engineered with experience. Built for the field. Since 1973.
Scope of Work
Preconstruction & Design-Build
Early coordination can make the difference between reacting to challenges in the field and addressing them before construction begins. L&T works with owners, engineers, agencies, and project teams during preconstruction to review constructability, evaluate costs and schedules, identify potential conflicts, and develop practical solutions before work reaches the field.
- Constructability reviews and design coordination
- Cost estimating and budgeting
- Value engineering
- Construction scheduling and phasing
- Design-build coordination
- BIM and project coordination support
Civil & Structural Engineering
L&T provides civil and structural engineering support for infrastructure and site-development projects, bringing technical design together with hands-on construction knowledge. The team develops solutions around real site conditions, utility conflicts, agency requirements, constructability, and long-term performance.
CAD & Technical Design
Detailed design documentation helps translate project requirements into coordinated field execution. L&T develops and supports CAD drawings throughout the project lifecycle, from design development and utility coordination through construction documentation and as-built records.
- Detailed construction plans
- CAD drawings and design development
- Utility coordination and layout
- As-built documentation
- Design revisions throughout construction
