For all of you on land, you most likely didn’t notice that construction on our future home on the Seattle waterfront hit a major milestone this month.

Installation of the first concrete slabs for the future Passenger Only Ferry (POF) facility began last week – marking some of the most significant work on our future home that’s taken place above sea level!

The 42 deck slabs began arriving last week by barge and, in construction lingo, were “flown in” to position via crane. They are then fastened to the pile caps that crews installed during the first half of this year.

Most of the slabs are rectangular in shape and measure between 3 feet and 6 feet in width, and 20 feet to 40 feet in length.

After the slabs are connected to the pile caps, crews will create the floor of the shelter and walkway of our facility by pouring a thin layer of concrete, known commonly as “topping slab.”

In addition to supporting our future terminal, the deck slabs will also support utilities such as water and power. These utilities will be run beneath or through corridors that are cast into the slabs.

You can expect to see more deck slabs barged to the waterfront in the coming months, as crews continue construction on Washington State Ferries’ Seattle Multimodal Terminal at Colman Dock Project.

Exciting stuff! Be sure to check back for more updates.
