Preconstruction and construction of a new Toyota Vehicle Processing and Distribution Center (VDC), to replace the existing VDC facility, within the same paved (144 acres less 16-acre reduction) lot. The new facility will consist of a LEED Gold Certified 155,000 s.f. post production building, 5200 s.f. car wash and a 3,500 s.f. fuel island to replace multiple existing structures and consolidate the functions of the current Vehicle Distribution Center into a 21% smaller footprint. The project will create more efficient workflow, reduce vehicle movement and emissions, and increase site safety and update the seismic security of the facility.

Located near State Route 237 in Milpitas, California, Bridge Point Silicon Valley is an industrial complex comprised of two (2) ground-up, concrete tilt-up structures, together totaling 722,000 s.f. on a 35-acre site. The project is near big employment hubs such as San Jose, Oakland, and San Francisco, and close to major Fortune 100 operations within the Bay Area.
Greg Woolway, vice president and Bay Area officer for Bridge Development, shared about the project, â€śWe didnâ€™t want this to be a traditional warehouse. We have really cool wood features on these buildings. They have a lot of glass and glazing. You normally donâ€™t see that with industrial.â€ť
Existing Soil Conditions
Due to the projectâ€™s close proximity to the San Francisco Bay, just north of San Jose, the existing project site contained high levels of alluvial soil, making it too insufficiently dense to support the loads of new construction. To remedy this, Oltmans worked with Hayward Baker to propose an effective ground-improvement method in lieu of traditional drilled piles. The team opted for dynamic compaction.
Dynamic compaction uses the energy from a falling weight in a predetermined grid pattern to improve granular soils and fills. In this two-part process, in order to compact granular soil, the first step requires a 27-ton weight to be dropped repeatedly from a height of 60 to 70 feet at regular intervals of 7 feet on center throughout the site. This method eliminates two to three feet of sediment. Then, a surcharge of 10 feet is completed to further compact the clay soil and eliminate an additional three to four inches of sediment.
January 2020 Construction Video
In the video linked below, two rigs are completing a wick-drain installation across the proposed site for Building 2, prior to moving west towards Building 1. They are followed by DDC rigs which drop 27 tons of weight repeatedly onto a 15-foot-by-15-foot grid during two passes. Next is an ironing pass, using a 10-ton weight, spaced out among a seven-foot by seven-foot grid. Upon completion, the site elevation is anticipated to settle approximately two feet by densifying the loose granular soils up to 15 to 20 feet deep. Following this process, the site will be surcharged, anticipating another three to four inches of settlement. Piezometers and settlement plates will be installed to track the progress.
Rehabilitation of the old Nissan warehouse & distribution center into a contemporary fulfillment facility. The revitalization and repositioning of the project includes decommissioning of Nissanâ€™s existing operations, demolition of the existing mezzanine, racking and two separate office buildings. The facility will receive completely new ESFR, plumbing, electrical, and mechanical systems with all new connections and equipment to handle the anticipated increased loads.
A brand new main entry facade with oversized glazing, and wrought-iron perimeter fencing will be added to the south side of the facility. Twenty-two new dock doors will also support the increase in fulfillment capacity, along with widening of the two existing truck approaches on Walnut St. Energy conserving skylights and LEDs will replace the existing system throughout and over 35 trees will be replaced with more drought tolerant landscaping. A retaining wall will also run the length of the property on the north side.

Phase 1-A construction includes mass infrastructure and grading as well as the creation of three (3) speculative concrete tilt-up warehouse and distribution centers (Buildings 1-3), which measure 62,340 s.f., 164,609 s.f., and 204,538 s.f., respectively. Phase 1 broke ground in August 2017 and is expected to begin deliveries during Q3 2018. Oltmansâ€™ scope also includes the safe relocation of the 92-year-old Live Oak Manor rock archway, to make way for new improvements.
The Center at Needham Ranch is a 135-acre, master-planned business park offering state-of-the-art facilities on a speculative and build-to-suit basis. Once completed, the business center will provide up to approximately 4.3 million square feet of industrial, office, and research and development facilities.

Black Creekâ€™s IPT Harbour Way in Richmond, California lies on 10.59 acres along the San Francisco Bayâ€™s Harbor Channel. The facility has been designed as a 172,408-s.f. Class-A industrial, dock-high, speculative warehouse building with 10,000 s.f. of office space as well as an associated concrete surface parking lot. In addition to grading and the construction of the warehouse and office spaces, Oltmans Construction is also providing services for landscaping, utilities, open-space, and offsite and onsite improvements.
Due to the projectâ€™s location on the harbor, the project team was tasked with mitigating heavy bay mud and high ground water as they prepped for the building foundation. To do so, Oltmans Construction utilized Auger Cast ColumnTM and Drill Displacement ColumnTM (ACC/DDC) technology to increase soil stiffness, bearing capacity, and resistance to liquefaction. 18 inches in diameter and drilled to a depth of 50 feet, the ACC/DDCs were located and installed two beneath each interior pier for structural column support.
