Which clause of the New Zealand Building Code pertains to the design and construction of soak pits?

The design and construction of soak pits is specifically addressed under the clause related to surface water management in the New Zealand Building Code. This clause encompasses the requirements established to ensure that surface water is effectively managed, which includes systems like soak pits that are designed to absorb and disperse water into the ground. By managing surface water appropriately, the risk of flooding and erosion is minimized, contributing to overall site safety and stability.

The other options pertain to different areas: the earthquake performance clause focuses on structural integrity and stability during seismic events, the hazardous substances clause is concerned with the safe handling and storage of potentially dangerous materials, and the access clause deals with ensuring that buildings are accessible to all individuals, including those with disabilities. Therefore, the relevance of surface water management to soak pits makes it clear why this option is the correct choice.
