May marks many large milestones at the 5th and Columbia project. Most notably, curtainwall for the building envelope commences on May 16. Concrete continues to be a successful operation on both the decks and the elevator core. By the end of May, Levels 5 -11 decks will be poured and the core will be poured to Level 35. Tower steel erection will continue at an extremely fast pace. In a period of 10 weeks the erectors will have completed floors 1 - 21. A planned steel erection break will occur on May 16th. This stop will allow the core to push out ahead of steel enough such that the remainder of the building steel will be erected in one continuous phase. In the garage, fireproofing work is ongoing throughout the month, and fireproofing will be complete through Level 8 by the end of May.
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.
The north sidewalk between 5th Avenue and 4th Avenue will remain closed throughout the duration of the project as this is a concrete pumping station and will serve as the location for a construction elevator and other primary building functions.
Street improvements are beginning along 4th Ave. This will include closing the northeast sidewalk at the intersection of 5th and Columbia from Columbia street to the Rainier Club. The final zones of structural steel will be delivered at the beginning of the month before the break in steel erection. On the 16th, deliveries of curtain wall glazing unit bunks will begin.
