Which document signals the start of survey activities and is transmitted to the contractor?

• A. Letter to Contractor
• B. Notice to Survey
• C. Notice to Proceed
• D. Permission to Operate

Answer: (B)

The main idea here is understanding how specific formal documents trigger distinct phases in a project workflow. A Notice to Survey is the document that officially signals the start of survey activities and is sent to the contractor to initiate field surveying work. It marks the formal kickoff of data collection, measurements, staking, and alignment tasks that precede design and construction, ensuring everyone is on the same schedule and scope.

A Letter to Contractor is a general communication and can cover various topics, but it doesn’t specifically authorize or initiate surveying work. A Notice to Proceed is typically the authorization to begin the overall contract work on site, not limited to surveying tasks, and is issued once prerequisites are met. Permission to Operate relates to enabling operation of equipment or facilities and isn’t about starting survey activities.
