uran areas %here strict restrictions %ith re!ards to noise and virations are imposed y relevant

authorities %hich restricted the use of other conventional pilin! system, e.!. driven piles. ecause of the

3< E)CAVATI!N #ET(!D

Due to space constraint, open e-cavation %ith earth slope is not feasile. Therefore, temporary structure or

permanent that allo%s for vertical cut need to e employed. :ethod considered include temporary sheet

pile, diaphra!m %all system, conti!uous ored pile %all, top do%n construction method and etc. Due to

economic factors and ease of construction, it is proposed that temporary steel sheet piles %ith !round

anchors shall e adopted as the temporary structure for the vertical cut.

The proposed steel sheet piles need to e installed vertically at a minimum distance of 6 meter a%ay from

the asement %all to provide for the necessary %orin! space, form %ors and any other temporary

structures re8uired durin! asement construction. The temporary sheet piles shall e removed and voidsshall e filled %ith suitale earth upon asement %all completion.

Durin! the sustructure construction %ors, the contractor shall ensure that sheet piles are providin!

proper support to the sides of e-cavation under the %orst comination of lateral earth pressure and

!round%ater pressure, includin! the possiility of the %ater level risin! temporarily to the !round surface

Temporary steel sheet pil in! is proposed to e adopted as the most effective means of

minimisin! retainin! %all displacements and thus dama!in! movements in the soil mass outside

of the site area. /round conditions also allo%ed the use of temporary sheet piles to form the
