The correct answer is E. 12 m (40 ft). When routing conduit under a pipeline crossing, the conduit must extend a minimum of 3 m (10 ft) beyond the outer edge of the pipeline on each side. This ensures the conduit ends are clear of the pipeline footprint for safe access and future maintenance. With the two pipe runs…

Explanation

When routing conduit under a pipeline crossing, the conduit must extend a minimum of 3 m (10 ft) beyond the outer edge of the pipeline on each side. This ensures the conduit ends are clear of the pipeline footprint for safe access and future maintenance. With the two pipe runs spanning 6 m (20 ft) between outside edges, you add 3 m (10 ft) on the left side and 3 m (10 ft) on the right side: 6 m + 3 m + 3 m = 12 m (40 ft). Choices A through D all fail to account for one or both of the required 3 m (10 ft) extensions beyond the outer pipes.
