Civil Engineering

Site development and building construction requires special attention to many environmental and regulatory conditions. Comprehensive site engineering is founded on awareness of distinctive site features, soil properties, traffic patterns, storm water management and vital utility infrastructure.  HGA's extensive site engineering knowledge and experience informs their civil engineering practice and collaboration that responds to the client's project goals.

HGA's civil engineers prepare plans collaboratively with project teams and in close coordination with reviewing authorities and permitting agencies. Viable design options are evaluated to determine preferred solutions that achieve project goals. Obtaining informed decisions and approvals from stakeholders and permitting agencies is an essential part of our design process. HGA civil engineers offer reliable solutions to today's site engineering challenges.
