Location: Laguna Niguel, CA

Project Partner: Mill Creek Residential Trust LLC

Challenge: Building soil nail and soldier pile walls into a steep slope.

Overview: Condon-Johnson was contracted to construct a 34 foot tall soil nail wall with soldier pile return walls on each end to allow for a new residential structure to be built into the existing slope.

Results: The work required close coordination with the general contractor and their excavation contractor to allow for sequenced installation of soldier piles as the soil nail wall and excavation progressed. A Lodril was used to reach the soldier piles that were difficult to access. The wall was finished off with a reinforced shotcrete facing with a rubber float finish.
