Maintenance (or access) holes and cable trunking runs are enclosed with access covers arranged in a multipart or trench run configuration. These enclosures are
large reinforced concrete structures, sized according to the cable arrangement
and may also be used to cater for the co-existence of other services/utilities or
house equipment.

The design of these underground spaces are bound by the wiring rules set out in AS/ACIF S009. AS/NZS 3084 also offers some basic guidelines.

The construction of these underground spaces are usually fabricated on site or supplied as precast reinforced structures.

ACO’s access covers are designed to be installed above them in a multipart or trench run configuration (trench run multiparts).
