DESIGN AND CONSTRUCTION OF TUNNELS FROM SPENCER STREET YARDS TO FLAGSTAFF STATION FOR THE MELBOURNE UNDERGROUND RAIL LOOP

Four 7M diameter tunnels have been completed in mixed ground conditions west of the new Flagstaff station for the Melbourne underground rail loop. The variable geological ground conditions presented problems for the designers which resulted in fairly strict specification requirements on the order and method of working. After the award of the contract a continuing assessment of the exposed ground conditions by the engineer assisted the contractor in proposing alternatives to the order and method of working which resulted in cost and time savings to the client - Melbourne Underground Rail Loop Authority (MURLA). The number of the covering abstract of the conference is IRRD no 235185.
