Underground conduits should be an initial requirement.

• A. True
• B. Plus one
• C. False
• D. Not specified

Answer: (B)

In underground pathway design, planning for future needs is a key practice. The idea is to install not just what you need today, but also provide capacity for growth. This is captured by the “plus one” approach—adding an extra conduit beyond the minimum required now so you have a spare for future cables without having to dig again later. That’s why the best choice is the plus-one option: it reflects the standard practice of provisioning an additional conduit to accommodate future expansion, reducing disruption and cost down the line. If you only said it should be installed now without a spare, you’d miss the growth planning; saying it’s not specified or false wouldn’t align with the common design principle of provisioning for future needs.
