Often times, value engineering or design-build approaches to construction allow owners to realize greater value from a given product by streamlining the engineering and construction process. This premise often applies with intermediate/deep foundations and with excavation support structures.
H.B. Fleming has provided design-build services to cutomers for a variety of projects. Our history of innovative construction techniques, our ability to design in-house, and the ability of our field staff to execute complex work allows us to design and install cost-effective and efficient solutions for our customers.
Hardscrabble Rd; Auburn, ME – Proximity to property lines led to the design and installation of this anchored sheet pile wall. Because of the exposed wall height, installation of a conventional retaining wall would have encroached on the abutting property.
Helical anchors were augered into the underlying soils and then pre-loaded to prevent any wall deflection.
This displays the method of anchor to wall load transfer.
- Helical anchors derive capacity based on the principle of cumulative passive soil resistance applied to successive helices. The torque required to advance the anchor into the soil can be correlated to bearing capacity or pullout resistance. The capacity of the anchor is then verified by load testing individual anchors.
