A cut that became deeper
At 6th & Bixel, the soldier piles stayed in place when petroleum-affected soil required more excavation. Additional tiebacks and walers supported the revised depth.
A neighboring foundation can limit where tiebacks fit, even when there is room to install the soldier piles. Cefali & Associates designs soldier pile and lagging walls for large commercial excavations in Los Angeles, with anchors and bracing laid out around nearby structures and the space needed to build.
At G-8 in Downtown Los Angeles, soldier piles supported a deep excavation beside two historic buildings. An existing basement restricted conventional tiebacks, so the design used rakers where the anchors could not fit.
Site conditions
At 6th & Bixel, the soldier piles stayed in place when petroleum-affected soil required more excavation. Additional tiebacks and walers supported the revised depth.
At 12th and Grand, tie rods connected soldier piles across a narrow alley where a conventional tieback layout could not fit.
At G-8 at Eighth and Grand, soldier piles supported a 40-foot excavation beside two historic buildings. Three rows of tiebacks and rakers braced the piles; an existing deep basement restricted where conventional tiebacks could fit.
Published project work

Soldier piles were supplemented with tiebacks and walers when a deeper cut was needed.

Tie rods connected soldier piles across a constrained South Park alley.

Tiebacks and rakers braced soldier piles beside historic buildings and an existing deep basement.
Engineering scope
These projects show how excavation depth, neighboring structures, access, and the permanent work can change the support design. Your site needs its own geotechnical criteria and structural design. The contractor determines installation and construction means and methods.
