Micropile underpinning was installed at a Indiana school that was experiencing foundation settlement.

 

Project: Washington Middle School Evansville, IN

General Contractor: Danco Construction Co.
 Micropile Installer: United Dynamics, Inc. 2555 Cannon St New Albany, IN http://www.udipdi.com           800 359 4471 

 

Project Information: 

 Washington Middle School was being renovated and it was discovered that it was experiencing some differential settlement. Soil borings indicated the presence of fill material below the foundation. Traditional steel resistance underpinning and helical underpinning were selected originally by the design engineers as the choice of remediation. Upon review of the soil information, UDI was concerned with the capabilities of these underpinning methods due to the soils information provided. It would be possible for the helical piers to encounter cobbles/floaters in the fill thus negating the installation. The use steel resistance piers likewise could become compromised by the nature of the fill. To solve this UDI proposed the installation of small diameter hollow bar micropiles. The main advantage of the method would be the penetration of the fill material into the 'good' material below the cobbled fill.       

The passive installation of the micropiles would also allow for a greater factor of safety in strength and parameters. UDI mated Titan's 40/20mm hollow bar micropiles with Earth Contact Products MP 350 Underpinning Bracket (75,000-99,000 lbs capacity) to provide a competent underpinning system. UDI excavated the site and prepared the footings during the first day of operation. Once the brackets were mounted, UDI installed the micropiles, coring and simultaneously grouting the bars as they drilled 35' through the cobbled fill and into the good strata. Upon completion UDI’s crew was able to stabilize and lift the structure with the MP350 micropile bracketing system. By utilizing this application, UDI was able to complete the project with a three man crew in just over three days. UDI's vast experience in dealing with different underpinning techniques provided an economical solution to an otherwise difficult situation. 

 



Helical Pier Installation at Ocean House Hotel

Helical pier installation at Ocean House Hotel

By: New England Foundation & Stabilization Co.

Today marks the 6th day we have been at the new Ocean House Luxury Hotel. New England Foundation and Stabilization Co. was brought on site to install ECP (Earth Contact Products) Helical Torque Anchors to support the proposed event tent on the south lawn of the property that overlooks Watch Hill.  

 The Helical anchors will be recessed into lawn boxes that can be accessed when the tent is erected and will provide support to the tent guy wires, allowing proper tensile support in a strong wind load area, and ease of erecting and removing the tent during event set-up and tear down. The Helical Anchor installation is expected to be complete this week.

Please review the site photos below. We will post further photos and information once the project is complete.
