| Block 17 – Post-Construction Reporting Final reporting for construction of deep foundations often includes compiling the installation records, testing results, and documentation of any construction changes for the project files. Input for as-built records often includes locations of final pile/shaft location, cutoff and tip elevations, and changes in foundation element type or size recorded on the record plans. This documentation is typical for all deep foundation projects, and are not requirements just for laterally loaded deep foundation projects. Full documentation and publication of data at load test sites are recommended. Such data are needed for use in future similar projects and in the reliability calibration to develop quality resistance factors. See Chapter 12 for further discussion. 59 Additional Considerations regarding Design-Build Projects The process above includes discussion in various steps with regard to how the process may differ for design-build projects. Ina design-build project, the overall process is generally the same however, the roles may differ. For example, the agency or a consultant working for the owner agency may perform site exploration, site characterization, conceptual selection of foundation type and preliminary design, establish minimum performance criteria and minimum foundation testing requirements, and develop requirements for completing the design and construction. The design-build contractor’s design consultant, as the final designer or engineer of record, will develop the final design, including performing additional investigations, design analyses, and testing. The actual tasks performed by each party will vary by project. Some design-build projects will be procured after performing the tasks in Blocks 1 through 4 (possibly with only a limited subsurface investigation, with the design-build contractor responsible for determining the foundation type and developing the full foundation design. Less frequently, other projects will include a relatively detailed preliminary design that requires progressing through to Block 14, with overlapping procedures by the design-build contractor who would perform the tasks in Blocks 4 through 14 again as part of finalizing the design. The roles for the procurement team and the contractor are shown conceptually in Figure 5-1, with the potential overlap for design-build project roles conceptually indicated. Download 6.03 Mb.
