Projects Awarded from PEER TSRP RFP 20-02 and PEER-Bridge Program

January 29, 2021

PEER has continuing funding from the State of California related to the seismic performance of transportation systems. This funding supports the Transportation Systems Research Program (TSRP), the purpose of which is to lessen the impacts of earthquakes on the transportation systems of California, including highways and bridges, port facilities, high-speed rail,  airports, and other related structures. In September 2020, PEER issued a request for proposals, Solicitation PEER TSRP 20-02 , for one-year projects aligned with the current TSRP research priorities and vision.

In response to Solicitation PEER TSRP 20-02, 34 proposals were received. Each proposal received three independent reviews from the pool of more than two dozen reviewers. Based on the priorities of the pre-set TSRP vision, pre-defined evaluation criteria specified in the RFP, and factors such as the level of engagement with the PEER core institutes, 12 new projects were approved, comprising a total funding of $600,000. The following is a list of the 12 funded projects.

The PEER-Bridge Research program is a streamlined framework of the Caltrans bridge research program. A single master contract is established between Caltrans and PEER, and different projects in seven topic areas are executed as Task Orders under the master contract. In 2020, PEER issued two requests for proposals, Solicitation PEER-Bridge 20-02, and Solicitation PEER-Bridge 20-01. Three new projects were funded from PEER-Bridge Program in the last 3 months.

PEER thanks all the PIs who submitted proposals, and also thanks the efforts and detailed feedback from the reviewers.
