Earth retention engineering in Inglewood

Discuss your project

At Intuit Dome in Inglewood, below-grade construction occupied much of the site, with the court more than 30 feet below existing grade. Cefali & Associates and Malcolm Drilling worked together on earth support that limited excavation layback while preserving construction access.

The arena required different support around its court, internal pools, parking structure, stormwater tanks, and construction ramp. Selecting an earth retention system meant accounting for those spaces, the equipment working above them, and the support needed as construction advanced.

Site conditions

Earth support across a large below-grade site

Excavation and equipment loads

The shoring design accounted for cranes erecting the roof trusses, concrete pumps, and smaller lifting equipment. Those construction loads were part of the support design alongside the retained ground.

Support that preserved access

Most shoring used cantilever and tieback-braced soldier piles. At the entrance tunnel, unavailable tieback agreements led to cross-lot bracing placed above truck traffic. The support arrangement changed where anchors could not be used.

Temporary and permanent retained areas

The project also included permanent shoring at the sunken garden. Temporary excavation support and permanent retention have different design conditions, so their roles and the stages connecting them need to be established for each part of a site.

Engineering scope

From local project to your site

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.
