Upstairs Hallway - Eastridge "Our Kind of Cliffhanger"
This project has three components, which is all built differently.
The main house is a waterfront property at the bottom of a steep cliff. All machine and materials are delivered by barge. Concrete is pumped from the top of the cliff down to the bottom with a 400ft line into a boom pump which was delivered by barge. Due to the challenging access to the site, most of the structural backfill is actually Styrofoam (EPS) backfill.
The garage is built from the top of the cliff, with a 27ft tall foundation wall. We needed to excavate to solid bedrock in order to adequately anchor the foundation into the hillside. This tall foundation wall are 10″ thick with a double grid of rebar to retain approximately 350 cu yards of fill. Styrofoam backfill was also used. A funicular (tramway) is also being built on this project, which required it’s own building permit.
