Current Work (Updated 6/22/18)
PBOT’s contractor, McDonald Excavating, Inc., has remobilized and removed the surcharge material from the roadway corridor. The surcharge material, a granular all-weather fill product including sand and gravel, sat for 8 months over the fall, winter and spring to force the roadway to settle and compact and avoid future settlement. The contractor is now constructing the gap area between Meade Street and Porter Street (Tilikum Crossing). This area must be primarily constructed of lightweight fill in order to eliminate impacts on the Tilikum bridge approach. Low density cellular concrete (LDCC) is the chosen material for this segment, and workers have been pouring it into the area via hose connected to an on-site batch plant (see photo above). The next work item is to install the tops of the retaining walls, which will be constructed of precast “bench blocks” and poured concrete coping. The surcharge / retaining wall work is anticipated to be complete by the end of this summer.
A second contract is in process of being awarded to Goodfellow Bros, Inc. This contract will perform environmental remediation under the Marquam Bridge, install water and storm sewer mains and communication lines underneath Bond Avenue, and construct the roadway itself. This work is anticipated to begin in August and last through the following winter. Completion of Bond Avenue is anticipated in spring 2019.
