After working in earth retention construction in the Southern California market for almost a decade, founding principal, Dr. David Salter, recognized the need for highly competent, efficient and responsive earth retention design services that minimized design time without sacrificing quality.  Born from the desire to improve deliverable  consistency and quality, Dr. Salter established DRS Engineering in 2009 to meet the needs of owners, developers, general and specialty contractors with challenging geo-structural issues related to excavation support, slope stabilization and specialty foundations. 

Our design service fall in four broad categories:


  • Temporary Shoring

  • Permanent Earth Retention

  • Slope Stabilization

  • Specialty Foundations


Founded on over 40 years of experience we provide our clients with the most economical solutions based upon innovative solutions created to meet the project  challenges and provided  on time and within budget.


DRS Engineering provides full project support from concept through detailed design, plan and specification preparation, bid processing and construction supervision.

Theoretical reasoning alone does not suffice to solve the problems which we are called upon to tackle.
