Question 16 ప్రశ్న 16

Two hypothetical SOR work items have different initial-lead provisions. Item A includes an initial lead of 50 m, while Item B includes an initial lead of 1 km. Both items otherwise permit separate additional conveyance charges where the applicable lead exceeds the included distance. For a total authorized conveyance lead of 800 m, which interpretation is correct?

A Additional lead may arise under Item A, while Item B already covers the entire 800 m lead. B Both items automatically require a charge for 800 m in addition to their basic rates.

Question 17 ప్రశ్న 17

A water-supply project obtains selected earth from an approved location outside the project boundary and transports it for embankment construction. Excavated surplus soil from the project is taken to another authorized location for disposal. Which statement correctly distinguishes these locations?
