Which document records the initial scope and deliverables used for cost estimation?

• A. SOW
• B. Site Survey
• C. CRO
• D. O&M

Answer: (A)

Defining the work to be done and the deliverables that must be created is captured in the Statement of Work. This document sets the scope, lists the specific tasks, outlines the expected deliverables, along with acceptance criteria, constraints, and responsibilities. Because it lays out exactly what must be produced and when, it becomes the basis for cost estimation—allowing you to translate each deliverable into quantities, labor hours, materials, and equipment needs, and to attach appropriate rates and timelines.

A site survey, while useful for gathering site-specific data that informs estimates, does not establish the formal scope and deliverables for the project. A change request/order records alterations to scope after work has begun and affects cost, schedule, and deliverables, rather than defining the initial baseline. O&M focuses on ongoing operations and maintenance rather than the initial project scope used for budgeting.
