Andy Pilskalns,P.E. founded Castle Rock Geotechnical Engineering Inc. in 2004 after working with a number of regional engineering firms and construction companies combining for 25 years of experience.  Andy received his B.S. (1993) in civil and geotechnical engineering from Montana State University in Bozeman Montana.  Andy has extensive geotechnical and civil engineering experience working in the Rocky Mountain States and is licensed engineer in Montana, Utah, Colorado, Idaho, Wyoming, Nevada, North Dakota and Hawaii. His comprehensive and in-depth construction and engineering background is used to prepare practical and efficient geotechnical designs.

 

Andy oversees all drilling and excavation activities, ensuring timely field work including sampling and testing.  He also performs reconnaissance, field investigations, site evaluations, construction observations, photographic logs, and reports.  Andy spends his spare with his wife and children.

WHAT DO WE DO?

Geotechnical Engineering Report

  • 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 to share site information with the Client so they may make educated decisions with the design team.

Forensic Geotechnical Engineering

Castle Rock Geotechnical  Enginerring specializes in forensic geotechnical evaluations. Typically, this includes studying and diagnosing the cause of movement that has led to cracks, separations, and other types of distress in relatively newer buildings. Our evaluations typically culminate with written reports of our findings, opinions, and repair recommendations for the project. Common issues that may arise that a forensic geotechnical analysis can help with include:

  • Damages Resulting From Water Loss

  • Structure Analysis Related to Foundation or Soil Movement

  • Moisture Intrusion

  • Drainage & Flooding

  • Expansive Soils

  • Collapsible & Compressible Soils

  • Retaining Wall Failures

  • Determine Angular Distortion of Buildings

  • Asphalt Pavement Distress and Settlement

  • Tripping Hazards From Concrete Flatwork Cracking & Vertical Offsets

  • Corrosion to Concrete & Masonry
