GeoEngineers' Oakland Bay Bridge project required 60 eight-foot-diameter, steel-pipe piles to temporarily support the permanent pile foundation boxes.

GeoEngineers provided support for design and construction of 20 temporary sheet-pile cofferdams for the Oakland Bay Bridge.

Construction Design
An integrated suite of construction design services for contractors and owners building heavy civil infrastructure.
GeoEngineers’ national construction design team specializes in a suite of interdisciplinary engineering design services for heavy civil contractors. The centerpiece of the team’s practice is structural and geotechnical design for the temporary structures needed during construction—trestles, piers, and earth- or water-retaining systems like soldier-pile walls or cofferdams. Their technical services include temporary structural design, geotechnical investigation and design, temporary excavation support, soil-structure interaction, seismic modeling and dewatering—all under one roof. This approach gives contractors a single point of contact and more predictable pricing for complex and fast-paced infrastructure projects across the United States and abroad.
The team is led by professional engineer Steve Spencer, who has decades of design and management experience working for heavy civil-infrastructure contractors, and he’s backed by a talented team of structural and geotechnical engineers who are used to working as subconsultants under alternative project-delivery methods.
In addition to designs, GeoEngineers helps our clients understand how proposed structures and soil will behave under a variety of conditions and stresses—especially for projects in soft soils that are more vulnerable to seismic risks. Our engineers tailor their designs and risk analyses to each site and project-delivery method, including using performance-based engineering over traditional factor-of-safety methodology when appropriate.
A deep bench of GeoEngineers’ technical experts in more than 20 locations across the country expand the core services offered by the construction design team. For example, GeoEngineers’ environmental scientists can assist with permitting, environmental assessments and help deal with unforeseen environmental conditions like underground storage tanks. Whatever your project challenges are, the team is ready to help.
