PROJECT NAME: 5TH AND YESLER

CONTRACTOR: LEASE CRUTCHER LEWIS

5th and Yesler was awarded to MDCI through the competitive bid process in the spring of 2006. The project, located in the area of Seattle known as Goat Hill, was constructed through a series of benches due to the steep slopes which surrounded the site. Through close coordination with the General Contractor and Earthwork Subcontractors, the shoring and excavation was constructed without incident and 3 weeks ahead of schedule dispite encountering hazardous soils and various other site logistical challenges. In all, MDCI installed a total of 125 soldier piles with an average depth of 57' at an average rate of 10 piles per day. The deeper 80' piles were drilled using MDCI's Soil Mec 825 which is capable of drilling up to 140' in its standard set (maximum of 250' with longer bars). The shorter piles were installed using the Watson 2500. The flexible design of the 2500 allows for drilling in rough terrain conditions as well as steeper slopes. All of the 500 tiebacks were installed using the Davey 725 drill machine which had no difficulty installing the tiebacks which were up to 100' in depth.
