Description:
 Dowco is close to completing the detailing of the above project, which is located in downtown Seattle, Washington, just a block south of the famous Pike Street Market.
The fabricator is Canron Western Constructors Ltd., a local firm located on Annacis Island, Delta, B.C. They will be splitting the fabricating of the steel between their Annacis and Portland plants.
The General Contractor is Sellen Construction, the Architect is NBBJ and Magnusson Klemencic Associates carried out the engineering.
This project is a 45 storey High Rise, with a further 7 floors below ground for parking. One half of the building will be occupied by Washington Mutual, and the Seattle Art Museum will progressively occupy the other half. Both parties have their own Architects and the Museum side has been designed so that entire floors can be removed as the Museum expands.
The project has approximately 12,000 tons of steel and Dowco so far has produced 74 Erection Diagrams, 121 Anchor/Embed Diagrams and 9,611 detail drawings. We estimate there are still about another 1,500 shop drawings left to detail.
The project has been split into 9 models by Dowco and the erector TEC further broke it down into a total of 100 divisions.
Modeling and checking of the main steel commenced in April 2004, with the initial main concern being to provide Canron with the Reserve Bills. The rising cost of steel and Canron’s need for work in the shop resulted in a very aggressive detailing schedule.
From April to August we were confronted by 7 separate construction drawing releases, the last one being the 100% set. We were initially released to detail 4 levels in the parkade, and then later were given the go-ahead to proceed on levels 18 to 31. The remaining floors were released for detailing when the 100 % set was issued in late August. However the erection schedule was not going to be adjusted to suit the late drawing release.
Even with the entire Whonnock office now assigned to the project, we still could not keep up with the aggressive schedule and customer revisions. In December our Toronto office was brought in to work on levels 6 to 9 and 14 to 17. Without their help, erection would have been delayed for at least 3 months.
 The project has been quite the challenge for both offices, especially Toronto because they had to absorb 9 months of correspondence in a short period of time. To date Sellen has issued 960 RFI’s and Dowco has issued 600 RFI’s, along with 117 Extra work orders.
At time of writing this report, TEC has erected up to level 6, and the elevator core wall has been poured up to level 17. The feedback we have received from the field on how well this part of the project has gone together has been very positive.
I would like to congratulate everyone in Toronto and Whonnock involved in this challenging project - you all did a great job keeping up with all the revisions, changes and information thrown at you.
