What is the FDOT Concrete Field Inspector's primary responsibility on a project site?

• A. Approve all subcontractor activities on site.
• B. Verify compliance with contract specifications, perform and witness tests, document results, and ensure proper placement, curing, and protection of concrete.
• C. Manage material procurement and inventory exclusively.
• D. Schedule maintenance for construction equipment only.

Answer: (B)

The primary responsibility of an FDOT Concrete Field Inspector on a project site is to ensure concrete work meets contract specifications through active quality control, testing, and thorough documentation, while overseeing proper placement, curing, and protection of the concrete. This means checking that the concrete mix design is followed, performing or witnessing required tests (such as slump, air content, and strength tests for cylinders), and recording the results accurately. It also involves supervising how the concrete is placed, consolidated, finished, and cured, and ensuring it is protected from damage or adverse conditions until it reaches the required strength and durability.

This role is not about approving all subcontractor activities, which would go beyond the inspector’s authority, nor is it about exclusively managing material procurement and inventory or scheduling maintenance for construction equipment. Those tasks belong to other project roles, while the inspector’s focus remains on compliance, testing, and concrete workmanship on site.
