APPENDIX D GUIDE SPECIFICATION FOR LATERAL LOAD TESTS
This appendix provides a guide specification for the performance of lateral load testing of deep foundations. This guide specification covers the lateral load testing only. Other specifications will be needed for installation of the foundation elements and other testing, such as dynamic pile testing, integrity testing, axial load testing, proof testing or other types of tests. Refer to Hannigan et al. (2016), Brown et al. (2010), Brown et al. (2007), and Sabatini et al. (2005) for guide specifications for driven piles, drilled shafts, CFA piles, and micropiles, respectively. This specification does not address measurement and payment terms as those will vary by owner, project, and/or contracting approach. Lateral load tests maybe paid individually, included as part of an overall testing program (may include multiple lateral load tests or axial load tests as well, or maybe included in the Lump Sum price of a Design-Build contract. Except in a Design-Build contract, lateral load tests would typically be paid on a unit price basis pertest. The construction of the foundation test elements is typically paid fora separate pay item, per each, since the effort and time required to install these individual elements is usually much greater than the installation of the same elements in a production operation. Alternatively, the cost for the foundation test element, including reaction system, can be included in the price for the lateral load test. Lateral load testing of deep foundations should be performed in accordance with ASTM D, Standard Test Method for Deep Foundations under Lateral Load. The specification below is intended to be a guide and is not intended to be used directly for project applications. Commentary in the specification below is provided in italics.
