Treasurer Matt Scerbak, division manager of Associated Pile & Fitting: “Loyalty and Longevity” 69 Optimizing Construction of Sellwood Bridge Nathan E. Glinski, E.I.T., Paul J. Axtell, P.E., D.GE, and Mike Lopez, P.E., S.E. The Sellwood Bridge replacement project involves construction of a 1,976.5 ft (602 m) long structure spanning the Willamette River in Portland, Ore. The new steel deck arch structure is located on the same alignment as the previous bridge which was moved laterally. The specialty contractor proposed a Value Engineering (VE) study to reduce the length of the drilled shaft rock sockets in an effort to mitigate risks associated with construction of very deep sockets in hard rock. DEEP FOUNDATIONS • SEPT/OCT 2016 • 3 COVER STORY 14 The Keys to Success in Waikiki Alison Savage, P.E., and Michael Terry, P.E. ® DEEP FOUNDATIONS The Magazine of the Deep Foundations Institute (DFI) is published bimonthly by DFI. 326 Lafayette Avenue Hawthorne, NJ 07506 USA T: (973) 423-4030 | F: (973) 423-4031 Email: [email protected] Executive Director Theresa Engler, [email protected] For decades, the International Market Place (IMP) has been an icon in the heart of Waikiki in Honolulu, Hawaii. It was discovered that the historical site had hidden and challenging foundation conditions, including a very deep but now in-filled ancient river valley containing more than 180 ft (54.9 m) of lagoonal deposits consisting of normally consolidated plastic clayey silts and silty clays. The silt was underlain by several soft coralline layers, some overconsolidated clays and various basalt layers. The static ground- water level on the site was at a depth of about 5 ft (1.5 m), closely matching sea level. Due to cost, schedule advantage and technical merit, a micropile option was selected.
