b'Structural Compressive Pile and/or Tensile Helical Anchor Installation ProcedureGeneral Considerations: Prepare site for safe working conditions. Thoroughly investigate the site for any and all underground utilities before excavating. Excavate as required for installation of the product. Install ECP Helical Torque Anchor to depth and torque specifications Cut shaft to length and install a pile cap or wall support assembly as specified Load test to verify design and capacity of the product and installation Remove equipment from work area and clean work areaInstallation Plan:The torque anchors shall be installed as shown on the written new construction or repair plan that wasprepared by the engineer or the installer, and submitted to the owner or their representative.The planshall include, but not be limited to: Size and number of placements Helical plate configuration Spacing between helical torque anchorsMinimum depth of embedment Minimum target torque requirement Load testing requirementsSTEP 1Installation Requirements: The minimum average installation torque and the minimum length shown on the plans shall besatisfied prior to termination the installation.The installation torque shall be an average of theinstallation torque recorded during a minimum of the last three feet of installation. The torsional strength rating of the torque anchor shall not be exceeded during installation.If thetorsional strength limit for the torque anchor has been reached, but the anchor has not reached thetarget depth, the following modifications are acceptable:A. If the torsional strength limit is achieved prior to reaching the target depth, the installationmay be acceptable if reviewed and approved by the engineer and/or owner.B. The installer may remove the torque anchor and install a new one with fewer and/orsmaller diameter helical plates with review and approval by the engineer and/or owner If the target depth/length is achieved, but the torsional requirement has not been met; the installermay do one of the following subject to the review and approval of the engineer and/or owner:A.Install the torque anchorfarther into the soil to obtain the required installation torsion.B. The installer may remove the torque anchor and install a new one with an additionalhelical plate and/or larger diameter helical plates.C. Reduce the load capacity of the placement and provide additional helical torque anchors at closer spacing to achieve the required total support for the project. If the torque anchor hits an obstruction or is deflected from its intended path, the installation shallbe terminated and the anchor removed.Either the obstruction must be removed or the torqueanchor relocated as directed by the engineer and/or owner and the installation resumed. In no case shall a torque anchorbe backed out and reinstalled to the same depth.If an anchormust be removed for any reason, it must be installed to a deeper embedment of at least three feet. Aftermeetingtheinstallationrequirements,theinstallermayremovethefinalplainextensionsection and replace it with a shorter one to obtain the design elevation, or he may cut the extensionto length.The cut shall be smooth and at 90 degrees to the axis of the shaft. It is not permissible toreverse the installation to obtain the desired coupling elevation.ECP Technical Design Manual - Installation & Testing2021 Earth Contact Products, L.L.C.2021-09 Chapter 4 - Page 70 All rights reserved'
