Children’s Healthcare of Atlanta at Egleston
Owner: Children’s Healthcare of Atlanta
General Contractor: Brasfield & Gorrie
In order to meet the increasing pediatric demands of the Atlanta area, Children’s Healthcare of Atlanta has expanded its Egleston campus to include a multi-level below grade parking deck attached to new interior hospital space.
The close proximity of adjacent roads and existing structures required that the perimeter of the site receive some type of earth retention to separate the grades. Therefore, we constructed a top-down permanent waterproof concrete shoring wall that combined a conventional temporary earth retention wall and a concrete foundation wall. The concrete contains a waterproofing admixture and serves as permanent lagging between steel soldier piles. This type of earth retention provides schedule and cost savings by eliminating the need to build two separate wall systems (one temporary and one permanent).
The shoring wall area totaled approximately 90,000 square feet with a maximum wall height of approximately 75 feet.
