💡Standard Operating Procedure

Standard Operating Procedure (SOP) refers to a set of step-by-step instructions compiled by an organization to help perform specific tasks. In the context of the video, SOPs are crucial for ensuring that road widening and strengthening projects are carried out according to established guidelines, maintaining consistency and quality in the work.

💡Road Widening

Road widening is the process of increasing the width of an existing road to accommodate more traffic lanes or to improve safety. The video script mentions road widening as a key operation, which includes adding width to old roads as per the required traffic lanes, as shown in the design plans or directed by the management.
