Site order book is used for recording A. Instructions by the executive engineers B. Construction measurements C. Issue of store equipments D. Names of the casual labour

The correct answer is: A. Instructions by the executive engineers.

A site order book is a document used to record instructions given by the executive engineers on a construction site. It is a vital tool for ensuring that all instructions are communicated effectively and that there is a clear record of what has been agreed. The site order book should be kept up-to-date and should be signed by both the executive engineer and the site manager to confirm that the instructions have been received and understood.

The other options are incorrect because:

• B. Construction measurements are typically recorded in a construction drawing or a field book.
• C. Issue of store equipments is typically recorded in a store ledger or a stocktake report.
• D. Names of the casual labour are typically recorded in a payroll or a timesheet.
