Block 14 - Develop Construction Documents
As the design is finalized, construction plans and specifications are prepared. In many cases, progress plans will be developed at earlier stages of the design process and periodically updated as the design progresses. The plans and specifications must clearly communicate the design to the bidders, including requirements for minimum tip elevations or penetration depths for the foundation elements, installation procedures, testing requirements, and quality control procedures. Requirements for testing should also be clearly communicated in the bid documents. If lateral load testing is required, then requirements should include a load test location, minimum design requirements for lateral load test setup, procedures for testing, definition of acceptance criteria, and reporting requirements. Lateral load tests are discussed in more detail in Chapter 12.
Block 15 – Develop Construction Cost Estimate
A construction cost estimate should be developed for the design that includes all relevant considerations such as likely construction issues or difficulties, specialty construction requirements, risks, testing requirements, etc. Cost estimates maybe developed at multiple stages of a project, such as preliminary design, design development, and final design, similar to the development of in-progress and final plans. The cost estimate may include estimates of more than one alternative design.
Block 16 – Design Considerations and Changes in Construction
Construction includes award of the contract, submittal of required documents, installation or construction of the foundations, construction inspection and testing, and construction reporting. Potential impacts, changes or considerations regarding the design for lateral loads are discussed in Chapter 13. Design changes during construction could have a major impact to project cost and schedule, and should be avoided by giving greater attention to site variability, design risks and constructability issues during the design process.
