Where the depth to suitable founding material is significant, excavated or drilled piers can be adopted. Where the length of drilled footing piers exceeds ENO
1500mm, they are to be reinforced with 4/N12 bars tied to an R6 spiral @ 150mm pitch or equivalent & tied into the Edge Beam Footing cage. FILL - Sandy Gravelly Slity Clay Mix
Alternatively an equivalent pre-fabricated steel cage may be adopted. Footing depth may be reduced where refusal on shallow rock is encountered, Y y
providing bracing and tie-down requirements are not adversely affected. When the required bracing and tie-down requirements are not attained rock (Brown) .
anchors must be utilised. Note; Pad footing depth and/or diameter is also subject to bracing and tie-down requirements. 3.0m Moist & Partially Compacted
The depth of the edge beam may be reduced where refusal on shallow rock, on a rock boulder or partially over a small rock outcrop is encountered. Laboratory Test Results Site Sketch (Not to Scale )

Where this depth is less than 400mm, top steel, comer bars and starter bars may be deleted. Note; Before the beam depth becomes less than 400mm,
top steel is to be lapped 500mm with the bottom steel. {tis also required that a minimum edge beam depth of 200mm must be maintained at all times. It Sample Location: BH#2
