Lampson International recently assisted on a project in downtown Seattle, WA, where we helped construct a new hotel.   R.C. Hedreen Company, LMN Architects and Sellen Construction all worked together to deliver 8th and Howell, a new 45-story Hyatt Regency hotel. The new hotel, featuring more than 1,200 guest rooms and 105,000 square feet of meeting and ballroom space, takes up three-quarters of the block.

For this project, Lampson International employed a Manitowoc 16000 with 157′ of main boom and 177′ of Luffing Jib that worked 23 months from August 2015 to July 2017. Operator Danny Youso said, “it was very productive and surpassed all expectations.”

Seattle shut down two and a half blocks of Howell Street for one day to erect the luffer, then two and a half blocks of 9th Avenue for two days for rig-down and load-out, which was all accomplished on schedule.

The Manitowoc 16000 set around 300 80′ H-piles on 6′ centers for the foundation and placed 9,200 tons of structural steel, averaging over 100 pieces per day.  In addition, the crane hoisted 138 pieces of structural steel in a single shift with a luffer, which was beyond all expectations.  It also picked and placed a number of 48,000 lb truss segments and set an 84,000 lb emergency generator in the basement of the hotel.  Working on a 60′ x 40′ pad of Lampson steel mats, the crane placed over 700 precast concrete panels weighing 14,000 lbs each.
