2. Field work findings

❌ close

Last week, you constructed a critical path on ClickUp for the Narromine to Narrabri project. Well done!! You also dipped your toes into the possible constraints that might impact that critical path.

In an ideal world, your critical path would look the same in the delivery phase as it did when you first put it together. In reality, though, as field work findings come in, you’ll often have curve balls thrown at you that push your timeline back. It can even result in having to change the track alignment altogether.

In such cases, extra investigations, reports, reviews, and board and government approvals all have to be completed. Finalising these approvals can easily add as many as 6-18 months to your critical path timeline, not to mention extra costs – for example, compensation for landowners impacted by resumptions along the new alignment route.

Have a look at the video below, to gain a better understanding of how Inland Rail conducts its field assessments, and particularly its cultural heritage surveys.

After the field surveyors have conducted their investigations, it’s time to ask the big questions: what constraints are we dealing with exactly, and how are they going to impact our project plan? 

The results are in!

The field reports have been submitted, and we’ve identified a number of ecological and cultural heritage concerns along the proposed alignment that are likely to impact your critical path and timeline.

Are you keen to find out how these assessments might affect the project plan and your critical path? 

Well, we’re almost there!

Before we dive into how we might mitigate these impacts, let’s take a moment to consider the protocol and legislation surrounding them. This will give us a comprehensive understanding of how biodiversity and cultural heritage is protected and regulated, as well as what mitigation strategies we’ll need to employ.
