Crews spent most of Tuesday dismantling the tallest of two tower cranes on the Wizer Block construction site in downtown Lake Oswego.
A mobile "assist crane" was set up on First Street on Monday, clearing the way for the removal of the 212-foot-tall crane that has towered over the mixed use project at First Street and A Avenue for months.
The process began with the removal of the counterweights behind the cab, followed by the main "jib" arm of the crane. At around 10:30 a.m., crews lowered the counter-jib arm, leaving only the tower portion and its empty cab jutting toward the sky.
"They can do these things in a day, typically," Project Manager Matt Baker said Tuesday morning, and he was right: the vertical tower came down piece by piece throughout the afternoon.
The dismantled crane was the second of two that were installed on the site, but Baker said it came down first because it was used primarily to service the building along A Avenue, which has now topped out. The remaining 171-foot crane at the Wizer Block's southwest corner serves more of a general-purpose roll, and it will remain in place until this fall.
"The (other) one serves most of the rest of the site due to its reach," Baker said. "It covers two of the buildings and the courtyard, and it takes all our deliveries on Second Street."
Both lanes of First Street were closed during the dismantling process, although the south end of the street remained open for access from Evergreen Road into Lake View Village. Drivers were forced to follow detour signs posted along A Avenue to alternate routes in the downtown area.
That was expected to change on Wednesday, though; First Street was scheduled to reopen once workers finished disassembling the "assist crane" and trucked it away.
Meanwhile, work continues inside and outside the Wizer Block's three buildings. Roofers, framers, masons, elevator installers and other craftsmen all are onsite, and developer Patrick Kessi says he now expects the Wizer Block's first residents to begin moving into their new abodes in the first quarter of 2018.
When it is completed, the mixed-use development will include 200 residential units, almost 43,000 square feet of commercial space and parking for 430 cars, of which 135 spaces will be for public parking.
