The Panama Canal Authority (ACP) released its Request for Proposal (RFP) Friday on the "design-build" contract for the new locks under the Canal's Expansion Program. Four global consortia will now move forward with their bids on what will be the largest and most important project under the $5.25b expansion. The Expansion Program will build a new lane of traffic along the Panama Canal through the construction of a new set of locks, doubling capacity and allowing more traffic and longer, wider ships. The ACP will meet with consortia representatives in February 2008 regarding the content of the RFP for the construction of the new set of locks. Proposals are due August 2008.
