A lawsuit by AECOM over its former construction unit's sale price remains unresolved.

Contractor Shimmick/Danny's Joint Venture still has claims pending against the owner over alleged breach of contract.

Contract covers the third phase of an upgrade and expansion project at the Regional Water Reclamation Facility in Lake Elsinore in Riverside County.

Work on the nearly $100-million perimeter pile upgrade on the 645-ft-tall residential tower to prevent significant future settlement follows the resolution of litigation.
