Mini borer makes de­but

Hills Gazette (Kalamunda) - - NEWS - Kristie Lim

A MINI tun­nel-bor­ing ma­chine on Rail­way Pa­rade in Bayswa­ter made its de­but yes­ter­day as part of the $1.86 bil­lion For­rest­field­Air­port Link project.

The rail link will de­liver a new rail ser­vice to the east­ern sub­urbs of Perth – with three new sta­tions at Redcliffe, Air­port Cen­tral and For­rest­field. The link will come off the ex­ist­ing Mid­land line near Bayswa­ter sta­tion and run to For­rest­field through twin tun­nels.

The ma­chine will tun­nel un­der the Mid­land line and fin­ish on What­ley Cres­cent, a dis­tance of 108m, in­stalling two pipes side by side.

It is 3m long and weighs about 7 tonnes. The cut­ter head di­am­e­ter is 1.5m.

Af­ter City of Bayswa­ter ap­proval, a 50m-wide sec­tion of What­ley Cres­cent was closed be­tween Anzac and New­ton streets from June 14 for up to eight weeks, as part of works for the re­lo­ca­tion of a main drain.

May­lands MLA Lisa Baker said the tun­nel was a “mini-me” ver­sion of two large ma­chines, Grace and Sandy, which ar­rived at Air­port Cen­tral sta­tion in May.

“It is like the tiny off­spring of the huge tun­nel bor­ing ma­chine,” she said.

“This is all be­ing done with the mini bor­ing ma­chine be­cause we have got wa­ter lines that have to be moved to make way for the line that comes in. “It is just the gate­way that is a start­ing point for open­ing up the Bayswa­ter re­de­vel­op­ment.”

Ms Baker said the What­ley Cres­cent clo­sure was a small in­con­ve­nience for a ma­jor de­vel­op­ment.
