Castle Rock Geotechnical Engineering provides Geotechnical and Civil Engineering resources for Clients and their assorted projects throughout the North Western United States. We have collaborated for 20 plus years with the Construction Industry in Montana and the Rocky Mountains with no claims, a testimony to success. We believe that engaging with people in the process of optimizing their construction goals and project value is worthwhile.


Geotechnical Engineering –  Our soil or geotechnical reports for commercial and residential building construction projects are prepared by a registered professional geotechnical engineer. We obtain information on surface conditions and subsurface materials and conditions, along with relevant physical, mechanical and chemical properties so the site may be evaluated for potential hazards and determining foundation design.


Industry Standards, intrinsic to Castle Rock Geo.

Our geotechnical process is the same used by any successful

geotechnical engineering firms.


•  Project begins with listening to a Client’s goals, schedule
    and budget.


•  Typical goals are to obtain subsurface ground assessment,  
    soil data for a particular site or location. The information
    may be used for road, building septic, subdivision, property,
    construction, pre-development, permitting, mitigation and
    remediation purposes.


•  If no existing information exists for a project site, ‘initial
    research’ is conducted in the office to discover relevant

    public and geotechnical information.


•  Client goals, budget and scheduling along with initial

    research determines proposed subsurface investigation

    method is proposed to the Client for authorization.


•  Upon Client authorization the field investigation is organized

    and proceeds in a timely manner.


•  Our protocol is share site information with the Client so they

    may make educated decisions with the design team.


The Geotechnical Report is typically organized with text portion.


    •  Executive Summary

    •  Project Location

    •  Research

    •  Geo-Environment

    •  Subsurface Investigation Information

    •  Subsurface Condition and Materials

    •  Bore Data

    •  Groundwater Condition

    •  Testing

    •  Geo-Hazards

    •  Details of Ground Improvement

    •  Earthwork Considerations

    •  Construction Recommendations.


Report contains site, topographic, vicinity and bore maps,

boring logs, figures, test plates, analysis and definitions.


Construction success requires detailed quality recommendations and Engineering oversight for ground improvements during construction. Engineering so finished products last a lifetime and more.


Forensic Reports and Geo-related Hazard Reports may be

structured differently, but are prepared with the same level of

expertise.


Though soils and “geo” are synonymous, they refer to somewhat different services. A geologic report is prepared by a geologist or engineering geologist. Soil/geologic reports are completed in geographical areas where the expertise in both engineering and geology are necessary. Castle Rock Geotechnical Engineering collaborates with a professional geologist when necessary to prepare soil/geology reports and studies.


Foundation Engineering


Castle Rock geotechnical has provided thousands geotechnical and civil recommendations for shallow and deep foundations, landslides, septic, subdivision approval work, COSA’s, structural and forensic analysis and review in the northwest region of the USA with exceptional success, evidenced by zero claims.


Foundation and land stability engineering in the mountains has long been the fire in which we’ve proven our metal. Contact us to receive accurate and reliable recommendations made by our skillful and experienced geotechnical engineer. We want you to benefit from using the right equipment, technology, and engineering, as our Clients have.


Castle Rock provides a range of geotechnical, foundation, and civil engineering consulting services.

OUR WORK


Value Engineering


Our business is based on client success, engineering ethics, and accountability. We are dedicated to providing cost effective designs that last as they should, a life time and longer. Our goal is to deliver geotechnical assessments that state the geotechnical hazards that may exist for a site, and the risks associated with them, as defined by governing agencies.


Project costs are greatly influenced by discovery and field findings. Research summarizing public information, field work, and construction observations leads to design success.


In some instances, overly conservative designs cannot be built due to prohibitive expenses; conversely, under-designed projects are dangerous.
