The above listed new project awards further enhance our backlog giving Great Lakes clear revenue visibility well into 2026. In addition to the above awarded projects, Great Lakes has approximately $350 million in low bids and options pending award, which includes three jobs that we were low bidder on in the past two months bringing our potential total pipeline of work to over $1.5 billion.
