The two-day concrete pour created the base slab of cell one for the north island receiving shaft at around 180 cubic yards of concrete poured per hour. In total, 33 concrete trucks completed multiple roundtrips from the concrete batch plant to the project and three concrete boom pump trucks were involved in the pour.

“The team is excited to continue working on this project that will enhance VDOTs resilience and improve transportation infrastructure along the Hampton Roads corridor,” says the Project’s Quality Assurance Manager (QAM) and Dewberry Senior Associate and Senior Project Manager Christian Brumm, PE, PMP. “Each member of the team has been critical in aiding the HRBT program, and it’s exciting to see this monumental moment come to fruition.”

With more than 30 continuous hours spent pouring, Dewberry provided QA testing of the delivered concrete. Field testing included measuring the concrete’s temperature, slump, and the amount of air present in the mixture. Concrete test cylinders were also prepared for laboratory testing to verify the concrete reaches the required strength.

The HRBT expansion is a multi-phase project connecting the Hampton Roads peninsula to the Norfolk and Virginia Beach areas across Interstate 64.
