USA: Project promoter Santa Clara Valley Transportation Authority has awarded an engineering services contract covering Phase II of the BART Silicon Valley extension project. The contract with a joint venture of Mott McDonald and PGH Wong Engineering is worth up to $125m.

The planned 10 km southern extension from Berryessa to Santa Clara University includes an 8 km tunnel under San Jose, and would serve four stations.

The contract aims to advance the engineering design level of the project to 30% to inform costs and schedule estimates. These are needed for a request that VTA expects to make in early 2020 for funding from the Federal Transit Administration’s Expedited Project Delivery Pilot Programme.
