During the 12-month preconstruction period, the team streamlined vehicle processing pathways, which created a more efficient campus and consolidated the entire existing operation into a 21% smaller footprint. Design and programming also increased site safety and updated the facility’s seismic security.

Construction spanned 22 months, which involved ground improvements, construction and tenant improvements. A four-month phased move-in consolidated Toyota’s operations into the new building, while the project’s final phase included demolition of existing facilities and site improvements such as paving, striping and modifying site drainage. The project was completed in July 2022.

Existing utilities at the port drove the team to innovate. Crews installed approximately 2.5 miles of underground utilities, making new connections directly into a 100-year-old sewer main located 15 ft below the surface. To avoid conflicts, ground penetrating radar was used prior to any excavations, while a spotter stayed ahead of the excavations to probe the trench for any undocumented utilities.

A 12-in. slab with two layers of rebar also served as a casting slab for the wall panels. Oltmans Construction Co.’s self-performing concrete team worked with the finishers and carpenters to form and finish the slab using a custom screed. Use of construction joints significantly reduced surface cracking. The work was further complicated by large trench drains spread across the shop floor.

Varying levels of contaminants across the site made for a tricky earthmoving process. Two environmental hygienists were on site during all earthmoving activities, tasked with testing excavated dirt to classify by level of contamination. Dirt was then segregated into different piles, resulting in about 3,000 cu yd of contaminated materials that were hauled off for proper disposal.
