CIVIL ENGINEERING | Our company performs a wide variety of engineering tasks ranging from residential septic system designs to wastewater treatment facilities, single lot subdivisions to large scale commercial development, private well plans to public water supplies and distribution systems. We regularly design water and sewer systems (both private and municipal), stormwater collection and detention systems, site layout and grading for access, parking and buildings. With our background also in structural engineering, G&A routinely designs concrete retaining walls and performs residential and commercial structural evaluations and design. These designs and projects frequently lead to numerous levels of permitting on both the local and state levels. We are involved in local permitting with the Planning, Zoning and Conservation Boards, as well as state level permitting for potable wells, water lines, sewer lines and wastewater treatment facilities and MEPA when the project warrants.
