Working on the WestConnex O&M contract in asset management has increased my awareness of how sustainability is frequently subtly incorporated into everyday choices. I recently discovered recurring work orders for component replacements that were happening earlier than their anticipated lifecycle while looking over monthly data integrity audits. When compared to condition data, these replacements seemed excessive even though they were technically compliant.
Since network reliability is our top priority and early replacement has always been viewed as the safe option, I initially felt uninterested. But as time went on, I began to feel uneasy about the waste produced and unnecessary financial expenditure, particularly in a network with over 250,000 assets.
I became aware of my unconscious belief that "more maintenance equals better outcomes." Even though it wasn't entirely consistent with sustainability principles, this belief had influenced how I understood job plans and standards.
Distinguishing real risk-reduction from habit was the main obstacle. Contractual restrictions, client expectations, and safety concerns make modifying maintenance intervals difficult. As an undergraduate engineer, challenging established practices can also be intimidating.
After giving this some thought, I started relating my findings to lifecycle thinking, which is essential to asset management frameworks. Sustainability involves more than just materials; it also involves making sure that maintenance activities add value rather than inadvertently adding to the environmental burden.
I am now more critical when examining maintenance patterns as a result of this experience. In the future, I want to confidently bring up instances where interval optimisation could cut waste without sacrificing safety using data trends. In order to facilitate sustainable decision-making in the O&M setting, I also plan to frame these recommendations using lifecycle logic.
During one of our weekly planning meetings, I noticed that several contractors consistently remained quiet during technical discussions about work orders and asset issues. Later, during a night tunnel closure, one contractor misinterpreted a job plan because he hadn't fully understood the earlier briefing but didn't feel comfortable asking questions.
I was initially irritated because I thought the communication had been clear. I felt guilty for not realising that silence did not always equate to understanding after having a private conversation with him.
This prompted me to consider my conviction that shared comprehension should inevitably result from the provision of structured information. I came to see that this presumption ignores how a person's cultural background influences their willingness to ask questions.
When people are reluctant to speak up, especially in groups, it can be challenging to identify miscommunication. This can become a hidden risk in operation and maintenance settings where safety and clarity are critical.
When I looked more broadly, I saw that the members of our teams have very different communication norms. For reasons of respect, some people might refrain from asking supervisors questions, while others might learn better from visual aids than from spoken briefings. This made me think about communication as a cultural exchange rather than merely a transfer of technical instructions.
I discovered that making room for quieter voices is essential to effective communication. In the future, I want to make a conscious effort to assess comprehension, make use of our pivot tables and charts when feasible, and ask to email myself or meet with me so that people can clarify without feeling pressured. This will facilitate more inclusive and safe cooperation throughout the WestConnex network through contractors, client and fellow company workers.
