What is the primary purpose of a manhole (MH) in construction?

The primary purpose of a manhole in construction is to provide access to underground services. Manholes are essential components of municipal infrastructure, including sewer systems, storm drains, and utility systems. They allow maintenance personnel and technicians easy access for inspection, maintenance, and repairs of the utilities and services that run underground.

While other options may seem plausible, they do not capture the essential function of a manhole. Structural support is typically achieved through other engineering measures, measuring soil conditions is conducted with specialized equipment and techniques separate from the manhole’s function, and excess water storage is managed through specific drainage systems rather than through manholes. Therefore, the correct choice emphasizes the significance of accessibility to vital underground infrastructure, which is crucial for the maintenance and operation of urban services.
