| (Commentary: It is generally required that the lateral load test program and test report be signed by a registered professional engineer in the state where the project is located. General provisions of the contract should cover aspects such as the time for the Engineer to review and return comments or approval on submittals. If not, add to this section that the Engineer will review the submittals within a specified period 10 working days or two calendar weeks is suggested) 1.2.2 Lateral Load Testing Plan At least 30 days prior to the start of testing, submit a Lateral Load Testing Plan that includes detailed step-by-step description of the planned test pile construction, instrumentation, load testing and monitoring procedure including personnel, testing and equipment to assure quality control. Provide sufficient detail to fully describe all elements of the test program, to the satisfaction of the Engineer. Include detailed plans for lateral load tests including shop drawings, details, structural computations and apparatus to measure test loads as well as pile top movement and displacements and strains with depth. Include the required instrumentation and monitoring described in this Specification and shown in the Contract Plans. The Lateral Load Testing Plan shall also comply with the requirements of ASTM D 3966. Include calibration reports for each test jack, pressure gauge, master gauge and related calibrated monitoring equipment dated within 60 calendar days of submission. Include proposed start date, order of materials, and schedule for installation. (Commentary: The Lateral Load Testing Plan provides an opportunity to review the proposed test setup, procedures, and instrumentation for data collection. The details of the plan will vary based on the reasons for the testing i.e., a test during design for developing site-specific geologic models for p-y curve development will have more instrumentation and maybe tested under more loads or deflections than a proof or verification test performed in construction to verify the lateral resistance of the foundation element. Some tests maybe monitored by the Engineer, others maybe monitored by a consultant working for the Contractor, such as a testing firm or an instrumentation and monitoring specialist) 1.2.3 Test Pile Construction Inspection Records Submit construction inspection records for the test piles. Test pile construction inspection records shall contain all required construction data as required in Section XXXX Driven Piles (or Drilled Shafts, Micropiles, or Continuous Flight Auger Piles. In addition, test pile construction logs shall include details regarding the installation of instrumentation, including locations within the test pile. Any deviations in the construction of the test pile from the Lateral Load Testing Plan shall be noted and the reasons for the deviations provided. The test pile inspection records shall be submitted within 24 hours of completion of the test pile and prior to the start of the lateral load test. (Commentary: The as-built condition of the test pile should be documented and submitted. It is assumed that the installation specification for the foundation elements will cover minimum reporting criteria for as- built conditions. All required testing, including integrity testing, should be performed and documented as part of the inspection it is assumed that this is covered under the foundation construction specification. 258 This section is based on the assumption that the quality control inspection is performed by the Contractor. Some projects will have the quality control inspection performed by the Engineer, Owner, or by a third- party inspection firm working directly for the owner. If the inspection is not performed by the contractor, Download 6.03 Mb. Share with your friends:
