STRATA has been providing clients with innovative designs in civil and geotechnical engineering for over 10 years with careful focus and attention to each individual project. Our package will offer clients more than the typical site design, through our use of three dimensional terrain imagery, earthwork volume takeoffs, and low impact development design approaches.  STRATA has also provided full or on-call assistance in the planning and permitting process under several types of jurisdictions.

Our staff and team of accomplished professional engineers and technical staff has experience in civil and geotechnical design including an array of earth structures, MSE walls, soil nail walls, and various ground improvement and drainage improvements related to proficient site development.  We continually gain client trust through our project management and unique site development methodologies built on effective communication and our in-depth professional understanding and experience. We will work with all involved parties to obtain a solid understanding of the project goals, issues, and requirements so a proper scope can be developed. With our site design services, we will analyze multiple approaches, along with stating their cost to benefit ratios and potential advantages and disadvantages to each alternative in the way of impacts to surrounding property, construction access, construction speed and safety, overall aesthetics, availability of local and experienced contractors, life cycle costs, and potential risks.

STRATA offers an experienced team of professionals and certified soils and materials technicians to support the full array of construction quality control, documentation and as-builting needs. These include technical reviews of submittals, site inspections, testing of soils and pavements along with a full service laboratory, special inspections and reports, erosion and stormwater control monitoring, change order request reviews, review of special permits, and final acceptance reports.  

With geotechnical design, STRATA approaches projects with the goal of involving the specialty contractor(s), allowing for a more streamlined delivery, oftentimes minimize change orders and contract issues.  Our staff is accustomed to performing under and catering design product to various types of bid, design-build, or CM/GC type contracts. STRATA has conducted several subsurface soil explorations, assessed geologic hazard indicators, and developed design solutions site foundation solutions such as soil nailing, deep foundations, and earth shoring and retaining walls (gabions, MSE, sheet piling, soldier pile wall).  STRATA has applied its expertise in often challenging environments of steep terrain and landslide mass conditions. These include experiences with the City municipalities to achieve goals and requirements set forth by the jurisdiction for geotechnical site investigations, project design, construction QA/QC, and report submittals.

Who We Are

Geotechnical Design Reports

Strata recognizes the importance of providing these values to the design team at the early stage of work. Reports include discussions on reuse of recycled crushed concrete and/or asphalt generated from site demolition as a resource for structural pavement base and/or backfill.

Low Impact Development Approaches (LIDA)

We provide design and analysis of low impact approaches to site development and stormwater management. Analysis includes utilizing hydrocad design software for iterative analysis and optimization of site options for stormwater detention, treatment, and infiltration to meet regulatory requirements. Using geotechnical analysis, we always include consideration given to reduce excavation quantity through the placement of geosynthetic fabric and/or cement amendment as a means to improve suspect subgrades.
