• Design Criteria

The roof of the covered walkway shall be designed to support a uniformly distributed load of 5 kPa. The catch platform shall be designed to sustain a uniformly distributed load of 5 kPa or a point load of 20 kN acting on an effective area of 300 mm × 300 mm, whichever shall produce the most adverse effect. Design criteria for covered walkway and catch platform are summarised in Table 3.2. The hoarding, covered walkway and catch platform shall be designed to sustain the wind load according to the current Code of Practice on Wind Effects in Hong Kong or its latest equivalent publication. The location of the proposed covered walkway shall be compatible to the existing traffic environment.

Typical details for the catch platform and covered walkway are illustrated in Figure 3.2
