The use <strong>of</strong> a crane is further detailed in the <strong>Site</strong> Safety Management Plan and its location<br />
indicated on a crane map - both are part <strong>of</strong> the project documentation.<br />
The skip bin and the site compound area will be located within the rail corridor near the site. The<br />
construction process will require an average <strong>of</strong> six vehicle movements and a team <strong>of</strong> three to<br />
six people on site per day.<br />
3.3 Timing and Costing<br />
Construction works for the proposal is planned to start in the first quarter <strong>of</strong> 2012 and scheduled<br />
to run for a period <strong>of</strong> six weeks<br />
Proposed construction timing:<br />
Standard working hours<br />
Evening/Weekends/Out <strong>of</strong> hours:<br />
Monday to Friday 7.00am to 6pm<br />

The DTRS project has an overarching value <strong>of</strong> $225 million. This includes the design, supply,<br />
and installation <strong>of</strong> the DTRS on the RailCorp electrified network plus a five-year life support<br />
component.<br />
3.4 Alternatives to DTRS<br />
As discussed earlier, the Waterfall Special Commission <strong>of</strong> Inquiry precipitated the<br />
recommendations regarding communications in NSW rail operations and within RailCorp. The<br />
NSW Government then committed to a state-wide strategy for all rail communications.<br />
RailCorp investigated a number <strong>of</strong> alternatives already used by the state government or<br />
available commercially, looking for a system that met its own safety and reliability requirements<br />
as well as the recommendations <strong>of</strong> the Waterfall inquiry.<br />
The government alternatives were the existing MetroNet system or the Government <strong>Radio</strong><br />
Network (GRN).<br />
The existing MetroNet communication system was not deemed a feasible solution for the<br />
reasons listed below.<br />
• It uses out dated technology and cannot be expanded due to its limited capacity.<br />
• It does not have the ability to support the requirements <strong>of</strong> Automatic <strong>Train</strong> Protection.<br />
• It only has one main supplier and this, combined with obsolete technology, means the<br />
cost <strong>of</strong> using and maintaining the MetroNet system is increasing at a substantial rate.
