Work on the South Whidbey Harbor expansion project is expected to resume this week.

The tentative start date to remobilize is Wednesday, Sept. 11 with crews beginning to install the piles again Thursday, Sept. 12.

The date to begin work again was pushed back due to poor weather conditions last week, said Ed Field, port operations manager.

Field said he is working with the City of Langley on final approval for the waterline for work on the shore. Once that is approved, Field said the waterline should be done within three weeks.

“We’re working hard to get on-shore work done before the weather turns,” he said. “It will still happen after the weather turns, but it’s a whole lot easier to do the work before.”

An accident in mid-August put crews from Neptune Marine behind schedule. A mechanical error caused the barge crews used to drive piles to tip.

The crane then slipped off the barge and remained underwater for a week.

Field said the project is still expected to be finished on the scheduled completion date of Jan. 27 next year.

Crews may work through some weekends to assure the project is completed on time, he said.

The project will add 400 linear feet of dock space to the Langley Marina. It is the first of several phases planned for the facility.
