I heard that Hayward Baker was working on the Corvette Museum sinkhole at GeoCongress, but I finally got official confirmation via this Civil Engineering Magazine article. It’s a great article if you are interested in the engineering that’s been going on since the sinkhole collapsed and swallowed 8 Corvettes. So far, Hayward Baker has installed 23 micropiles around the structure to depths of 75 to 220 feet depth according to the article. They are still trying to recover the remaining cars before a plan is formulated for shoring up the museum. They might use more micropiles, or they could go another way and fill up the sinkhole with low mobility grout. Whatever they decide to do, you can bet I will report on it!

DFI Announces the 2016 Outstanding Project Award Winner
Hawthorne, NJ (July 7, 2016): The Deep Foundations Institute (DFI) is proud to announce that Hayward Baker is the 2016 Outstanding Project Award (OPA) winner for the design and construction of foundations at the International Market Place in Waikiki Beach, Honolulu, Hawaii.
The award will be presented at the DFI International Conference on Deep Foundations, Seepage Control and Remediation (41st Annual Conference) in New York City, October 12-15, 2016.
Opening in August 2016, the International Market Place, a well-known retail, dining and entertainment destination, has undergone a complete revitalization. Hayward Baker was the foundation contractor for the construction of a new 80,000 sq ft Saks Fifth Avenue anchor store, a 7-story parking garage and two 3-story retail structures located on a 6-acre site in a heavily congested area of Waikiki Beach. The company installed 544 micropiles to depths of up to 315 ft to support the structural loads. Difficult site geological conditions and cultural restrictions presented significant challenges for the design and construction of the foundations. The project site was located within the boundaries of an ancestral Hawaiian burial ground that required pre-excavation prior to any installation of below grade improvements. Additionally, two existing historic banyan trees on the site had to remain in place and not be trimmed for equipment access.

Video: Secant or Tangent Piles
I like Hayward Baker’s series of videos using animations to demonstrate different geotechnical construction methods. This video demonstrates how tangent pile shafts or secant pile shafts are constructed. Check out the video. Note: Hayward Baker […]
