Less-than-perfect weather couldn’t keep two construction workers from scaling the base of a crane under construction yesterday morning at Pacific Plaza, located near So. 12th St. and Pacific Ave., in downtown Tacoma. After several decades as one of downtown Tacoma’s venerable eye sores, the former Park Plaza South is under renovation. Pacific Plaza LLC, a development group, is in the middle of a $32.5 million revamp of the building. When completed later this year, the building will boast two new floors of office space, one new level of parking, and expanded and improved street-level retail totaling 30,000 square feet.
