FAQs

What cable duct size and crossing arrangement does the document standard cover?

The document standard covers a 3rd party crossing arrangement using 125mm duct configurations, with additional layout variants shown for above-ground formations.

What installation depth and surface level requirements are specified?

It specifies a minimum burial depth (450mm) and identifies finished surface level references used to control the final installation geometry.

Which materials and markings are required for the crossing?

The notes require concrete placement with rapid-hardening wet mix grade, steel plates over the ducts, and the use of marker strips plus yellow warning tape as part of the warning/identification system.
