SR 520 Pontoon Construction Project

11

Why is the Pontoon Project needed now?

• Constructing and storing pontoons are key elements in catastrophic failure planning. 

• If the floating bridge failed, available detour routes would be overwhelmed with rerouted traffic.

• Recovering the bridge after a catastrophic failure will require new pontoons. We estimate it would take approximately three years to construct enough pontoons to restore the SR 520 bridge.

• Support accelerated schedule, reduce risk, and minimize costs

• Field test for pontoons, i.e., form systems, concrete mixes, full‐scale mockups of pontoon sections

• Advertise in Summer 2009‐‐Posted on WSDOT Contract Ad and Award Web site

• Located in Grays Harbor

Advanced Construction Methods and Engineering

Use existing facility at Concrete Technology Corporation

• Expedite pontoon construction to stay on schedule

• Does not have capacity to build all the pontoons

• Construction of pontoons to begin in 2010 

Two Sites in Grays Harbor

15

• Prepare site– Excavate a basin, drive piles,

pour concrete slab.– Stabilize sides of basin with

concrete walls; seal off from open water with a gate.

– Construct support facilities.• Construct pontoons

– Assemble forms around steel frame.

– Pour concrete into forms to create pontoon.

• Launch pontoons– Fill basin with water.– Open gate and use tugboat to

tow pontoon to moorage location.

– Drain basin and repeat process for other pontoons.

How are pontoons built?
