Which document is used to ask questions regarding installation ambiguities?

The correct choice is the RFI, which stands for Request for Information. This document is specifically designed to clarify uncertainties or ambiguities that arise during the installation process of a project. When contractors or subcontractors encounter issues or questions that may affect the work, they use an RFI to formally request clarification from the project owner, architect, or engineer.

By submitting an RFI, the contractor ensures that all parties are on the same page and that work proceeds according to the intended plans and specifications. This is crucial for maintaining quality, efficiency, and safety on the job site, as any misunderstanding can lead to costly delays or errors.

In contrast, the other options serve different purposes:

• A field change order is used to document changes to the original contract that occur during the project but does not specifically address ambiguities.

• A bulletin is typically a communication tool that outlines updates or specifications but may not be used specifically to request clarification.

• A daily report records daily activities and progress on a project but does not serve as a formal means of resolving ambiguities.

Therefore, the RFI is the appropriate document for addressing installation ambiguities, ensuring clarity and proper communication within a construction project.
