Final answer:
Field Adjustment Requests (FAR) and Design Change Directives (DCD) are used in naval construction to adjust project designs or scopes. FARs are typically initiated by project managers when changes are needed, and DCDs are formal instructions issued by design authorities. Both require review and approval to ensure project quality and adherence to objectives.
Step-by-step explanation:
In the context of a naval construction battalion, Field Adjustment Requests (FAR) and Design Change Directives (DCD) are formal methods for altering the original design or contract scope for construction projects. A FAR is a request that is commonly initiated by a project manager or field engineer when an unforeseen issue arises or when they believe an adjustment is necessary for the efficiency or effectiveness of the project. The approval of a FAR typically involves a review by the project's commanding officer or the relevant authority within the chain of command to ensure the change aligns with mission goals and resources.
A Design Change Directive is a formal instruction issued by the authority responsible for the project design, such as a design manager or other higher-level official. It can involve major changes to the design or scope and often requires a careful review process to assess the impact on the overall project, budget, and timeline. The primary purpose of both FAR and DCD processes is to ensure formal documentation, review, and approval of any changes to the construction project, thereby maintaining control and ensuring quality and adherence to the original objectives.
