Tender ID: 441976
Tender Details
Tender Description
The scope of works relates to the construction of the new Murchison East Crossing Loop due to the current loop having non-compliant track centres located in Zone 6 as shown in Figure 1. Upgrades include new track construction to extend the crossing loop, reconstruct existing mainline track, installation of new turnouts and crossovers and duplication of Murchison-Violet Town Road level crossing.
Construction of the new crossing loop will be broken up into three Zones as outlined in Figure 2. Majority of scope in Zones A and C will be completed normal time whereas Zone B scope will occur during occupation times. As part of the new crossing loop construction, the applicable earthworks and formation works are as follows:
- Bulk topsoil strip
- Bulk cut to subgrade
- Spoil haulage and disposal
- Stockpiling material
- Placement and compaction of structural fill
- Placement and compaction of capping
- Proof Rolls
- Placement and compaction of bottom ballast
- Cess Drains
Further geotechnical borehole investigations are currently being undertaken to provide a more detailed and accurate geotechnical profile which will be provided in the RFT. Where required lime stabilisation of subgrade will be managed through a separate subcontract.
The work time applicable to the above elements has been broken down into the following based on rail corridor constraints:
- Normal Time
- Occupation Time
- ALBF
