Grantham Engineering is a professional engineering consulting firm located in San Diego, CA. We excel in solving unique and challenging problems on smaller projects that are not cost competitive for the larger national firms. We focus on developing trusting relationships with the clients we serve; we want to be your on-call engineers. Our 3D Modelling capabilities enable clients to easily visualize and make early adjustments to the design saving them time and money. Our two principal engineers/owners have almost 40 years of combined design, engineering and project management experience in municipal public works, naval facilities, private industrial plants, and design-build projects. Additionally, we have developed a client list that includes boatyards, entertainment parks, churches, commercial and residential contractors, and architects. Currently we have a staff of 5 employees which includes a Registered Civil Engineer who specializes in grading, storm water and site design; a registered land surveyor who specializes in topographic and design surveys, a Qualified SWPPP Developer (QSD)/Qualified SWPPP Practitioner (QSP); and CAD designer/drafters. Our staff brings over 30 years of experience to the team in addition to the experience of our principals.
