Civil engineering designs the site improvements that connect commercial buildings to the surrounding infrastructure — grading, drainage, utilities, parking, driveways, stormwater management, and ADA accessibility. Apex Grid provides civil engineering for commercial, multifamily, industrial, and government site development projects, producing PE-stamped civil permit drawings. Apex Grid Engineering is licensed in 49 states — every U.S. state except Alaska. Engineering stamping and licensure are confirmed for each project jurisdiction.
Request Engineering SupportCivil engineering for building sites encompasses the technical disciplines that design what happens on and under the ground around a building: site grading to direct water away from the structure, drainage systems to manage storm runoff, utility connections to water, sewer, and storm infrastructure, parking and access improvements, and stormwater management to comply with environmental regulations. Apex Grid civil engineers work alongside structural and MEP engineers on commercial development projects, providing civil engineering as a standalone service or as part of a coordinated multi-discipline package.
