Virginia State Capitol

Draper Aden Associates was part of the design team for the planning and design of the complete renovation to the Virginia State Capitol and surrounding Capitol Square. The design completely replaced the existing building systems, added a 27,000 square foot building extension, related infrastructure and landscape improvements in Capitol Square. The project was designed to meet current programming needs, addressed the 2007 statewide celebration plans, and extended the useful life of the historic Virginia State Capitol.

Draper Aden Associates assembled complete base mapping for the Capitol Square, including some subsurface utility verification and supplemental ground surveys. We conducted a hydrogeologic study to determine anticipated impacts of groundwater and conducted a geotechnical study that included subsurface investigation, materials testing, and engineering consultation for the structural designs. We also provided an Environmental Impact Report in accordance with state standards for the project.

Our site engineering team provided civil engineering design for the grounds surrounding the Capitol to address the building extension, the new utility connectors, and waterproofing and structural repairs to existing tunnels. Plans included site design, erosion control, grading, drainage, stormwater management, and utilities engineering. Utility engineering services included utilizing a previously prepared master plan to develop water modeling and to design improvements for separating storm and sanitary sewer, upgrading waterlines to improve pressure conditions, and related private utility relocations. All work by Draper Aden Associates was closely coordinated with numerous state agencies and a design team of selected experts.
