About LDG

Lorenzi, Dodds & Gunnill was founded in Pittsburgh in 1953 by Silvio J. Lorenzi, a registered professional engineer and surveyor, with the goal of providing complete professional services in the field of civil engineering.  Since its founding, the firm has served commercial and institutional clients, federal and state governments, county administrations, towns and municipalities, as well as private land owners. 

Over the years, we have maintained strong professional engineering capabilities and broadened our services to include landscape architecture and environmental sciences.  Our engineers, planners, and surveyors are equipped with the latest fully integrated systems for computer aided design.

Clients look to Lorenzi, Dodds & Gunnill for creative economic design, meticulous attention to detail, and prompt efficient service.  Each project is managed as a unique challenge requiring a unique solution.  All projects are handled “under one roof” by a well trained and coordinated key staff of civil engineers, landscape architects, planners, and surveyors under the direct personal supervision of the firm’s President, James C. Lorenzi, P.E.
