Monorail Removal Project - Review of Environmental Factors (REF)

Task Description Plant/equipment Labour5 Measure locations to be cut and drill holes at locationof temporary supports.6 Install temporary supports to rail beams – two sets ofsupports required per span.7 Check temporary supports are secured, then flamecutremainder of beam through the full depth.Night 38 Secure beam segment to crane in preparation forlifting.9 Transfer beam segment load to crane, removetemporary supports, then lift and lower beamsegment to ground.10 Cut beam (on ground) if required, into transportablelengths and load onto truck for load out.11 Secure remaining T-unit to crane.12 Cut column at base, approximately 150 mm abovetop of pedestal.13 Lift and lower column onto truck for load out.The following activities are associated with phase 214 Install signage, temporary fencing, demarcation etc.required in preparation for concrete removal and civilworks. Make safe work area around pedestal for thefollowing shift.15 Locate and treat any below-ground services betweensurface ground level and top of pile cap, and removepavers or asphalt necessary for pedestal removal.daymakersutility truckmechanical toolsoxy-acetylene kit (incl.bottles)mobile craneutility truckgeneratorboom lift/elevated workplatformmobile cranedaymakersoxy-acetylene kit (incl.bottles)truck for load oututility truckhand and mechanicaltoolshand-held locatorsvacuum truck (ifnecessary)platformcrane operatorand dogmanboilermaker2 x work crewsoperator ofboom lift/workplatformcrane operatorand dogmanvacuum truckoperator andoffsider (ifnecessary)Areas requiring special attentionThe following areas would require special attention in phase 1 (see examples in Figure 5.3):• Expansion joints – These are located at or adjacent to stations, and consist ofdiscontinued beam sections with a joint in between. In these areas, full-height proppingfrom street level may be necessary to support one beam while the other is removed.• Tangential beams over intersections – At intersections such as Clarence Street andMarket Street, curved rail beams need to be removed. In these areas, traffic flow needs tobe maintained, thus restricted and varying traffic arrangements would need to beimplemented. Detailed traffic management plans would be developed to reflect thearrangements at these locations.• Rail beams at stations – The options to remove the rail beam at stations include removalof the rail beam with use of the station platform for access. It may also be possible toconduct a dual crane lift operation on either end of the station to slide the rail beam out ofthe stations for removal.• Major intersections – Where the Monorail crosses major CBD intersections, detailedtraffic management plans would be developed to customise the traffic managementarrangements.GHD | Transport for NSW - Monorail Removal Project REF | 29
