Morton Bay Rail project involve a 12.6km dual track from Lawnton station to Kippa-Ring station, the project scope includes six new railway stations and the upgrade of existing infrastructure (bridges, stations and creek crossings). Construction activities includes earth embankment that will form part of the rail foundation. Following the rail foundation construction works, concrete sleepers will be positioned for steel rails to be “clipped” into place (by track mounted machine or by hand), for stability ballast are placed between rails and under the sleepers and vibrated by a “tamper” that travel along the track lifting the tracks to settle ballast.
The overhead high voltage line masts are installed along the rail line to provide support for overhead conductors supplying …show more content…
The project includes 22 major bridge structures that will require some form of piling to provide appropriate foundation to support structures.
As part of the project, a noise assessment has been undertaken and areas that are effected noise walls will be installed to reduce the level of noise.
The aggregates requirements for the Morton Bay project were sourced form Holcim Quarry, Beenleigh. Up to 100mm rock was used for road settlement, Holcim is also supplying rail ballast as well as the aggregates for concrete mixes. The culvert rocks are larger rock and cemented into the slope of the culverts to prevent erosion.
WSUD filtering process involved multiple layers of different size stone and sand.
Station construction involved steelwork, concrete works, plumbing, and electrical installations. The 12.6km dual track are constructed with concrete sleepers and ballast, the high voltage overhead line was constructed with steel lattice structures for the route of the 12.6km of overhead
