WATSONVILLE, Calif.–(BUSINESS WIRE)–Granite (NYSE:GVA) and Healy Tibbitts Builders, Inc. announced today
that their joint venture team has been awarded a $27 million joint
venture contract by the Naval Facilities Engineering Command Southwest
for the construction of maintenance dredging at Piers 1, 3, and Paleta
Creek at Naval Base San Diego. The contract includes one unexercised
option, which if exercised would increase the cumulative award value to
$38 million. Granite will book $21 million, or its 78% share, of the $27
million contract in its second quarter 2019 backlog.

The project will re-establish the operational and berthing depth
required for United States Navy vessels and other visiting vessels, and
restore the pier slips and creek area for safe and unrestricted
navigation. The dredged material will be screened for unexploded
ordnance and radiological debris, dried or dewatered prior to transport
for disposal at a commercial landfill.

Construction is scheduled to begin in summer 2019 and be complete in
fall 2021.
