The Panama Canal Authority (ACP) has issued a request to carry out an excavation contract which it describes as its second biggest expansion project.

Rounding out the last of four dry excavations, the project represents a key portion of the port’s new access channel linking the new Pacific locks with the waterway’s existing Gaillard Cut (the narrowest stretch of the Panama Canal), the ACP said.

Project work involves the erection of an earth-rock filled dam that forms a portion of the access channel’s eastern bank, in addition to the fitting of a backfilled cellular cofferdam water barrier, the ACP said.
