Which stakeholder should be informed about the form liner profile?

• A. Project manager
• B. Site inspector
• C. Finishing contractor
• D. Structural engineer is informed of the form liner profile

Answer: (D)

Changes to the form liner profile alter the mold geometry and the resulting concrete panel dimensions and surface conditions. That can affect critical structural aspects such as concrete thickness in certain areas, concrete cover to reinforcement, and the alignment and placement of embedded connections. Because these factors influence strength, stiffness, and load transfer in the tilt-up panel, the structural engineer must be informed to review and confirm that reinforcement detailing, tolerances, and connection details remain valid with the new profile. While the project manager, site inspector, and finishing contractor play important roles in coordination, inspection, and finish quality, the responsibility for ensuring the design assumptions stay intact lies with the structural engineer.
