Major Activities

Shoring & Excavation:

Shoring and tiebacks are approximately 65 percent complete. Tiebacks will continue to be drilled in a clockwise fashion (looking north) as the excavation progresses. Night haul trucking began on March 23rd to reduce the impacts to the public and the environment. Tiebacks are scheduled for completion along with excavation in late April/early May 2015.

Public Impacts

5th Avenue

For safety, the west sidewalk between Columbia Street and Marion Street will remain closed to pedestrians throughout the duration of the project. The west side traffic lane will be closed for construction Monday – Friday, between 6 p.m. and 3 p.m. and on Saturdays (9 a.m. to 6 p.m.) as required.

Columbia St

The north sidewalk between 5th Avenue and 4th Avenue will remain closed throughout the duration of the project as this is an active truck haul route and will serve as the location for a construction elevator and other primary building functions.

Mobilizations/Street Closures

A conveyor system was mobilized on March 8th. A second conveyor will be mobilized on April 11th as the excavation will be too deep for a single conveyor. Tower crane erection is scheduled for May 30th and the mat foundation pour is scheduled for June 20th. All of these activities will require major street closures. Individual traffic control and logistics plans will be sent out as the dates of these activities near.
