Presidents Report - Welcome and Introduction


Welcome to the first newsletter of 2025! I’d like to start by wishing all our members a Happy New Year and thanking you for your continued support. I also want to acknowledge that this newsletter issue has been delayed – thank you for your patience. We’ve hit the ground running this year, and despite the late edition of the Condit, I’m excited to share our updates and plans.


The land development industry is facing some headwinds as we enter 2025. Economic pressures – from rising costs to interest rate impacts – are being felt across projects, and challenges in project delivery timelines continue to test us. However, despite these hurdles, our outlook remains overwhelmingly positive. Demand for development is still strong, and as an association we see opportunities for innovation and collaboration to overcome delivery challenges.


Engagement with Government and Stakeholders

Open communication and advocacy with government agencies and key stakeholders remain a priority. Recently, we had a very productive meeting with the Department of Transport and Planning (DTP) to discuss developer-funded assets. This discussion centered on how infrastructure funded and delivered by developers can be better integrated and accepted into the broader transport network. It was encouraging to see DTP’s receptiveness to industry input. We plan to continue this engagement throughout 2025, ensuring that the voice of land development engineers is heard in policy and process improvements. Our goal is to work with DTP on clear guidelines and smoother pathways for developer-delivered infrastructure, benefiting both our members and the community.


In addition, Melbourne Water has committed to providing an industry update via webinar in the coming months. This webinar will cover important updates on water and drainage issues affecting land development. We recognize not all members have direct access to these insights, so our association will partner with Melbourne Water to bring this webinar to our wider membership in the first half of the year. Keep an eye out for the date – we’ll ensure you have the opportunity to participate, ask questions, and stay informed on the latest from Melbourne Water. These kinds of collaborations with authorities are a key focus for us, as they help keep our members at the forefront of industry changes and best practices.


Revitalising Our Committees

One of the strengths of our association is our committee structure, which allows members to focus on specific aspects of our industry. I’m pleased to report that we have reactivated all our committees, and they are now meeting regularly. Each committee chair is providing monthly reports to the Executive, ensuring a steady flow of information and progress updates. This reactivation has really injected new energy and focus into our activities – and it means more opportunities for you to get involved in areas you’re passionate about. We encourage members to join or contribute to committees of interest; it’s one of the best ways to drive change and have your say in the association.


Key Committee Updates

  • Main Drainage Committee: This committee, led by Jamie Tainton, has been working closely with Melbourne Water on drainage infrastructure. Collaboration with Melbourne Water is ongoing to improve standards and processes for main drainage in new developments. The committee’s efforts are helping ensure that our projects effectively manage stormwater and flooding risks, and we thank Jamie and the team for strengthening this vital partnership.
  • Local Government Committee: Chaired by Jake Talbot, this committee is actively engaging with councils and is involved in the Engineering Design & Construction Manual (EDCM) Technical Committee. By participating in the EDCM Technical Committee, Jake and his team are helping to refine the standards that many councils use for land development works. This not only elevates the consistency of design across municipalities but also gives our association a voice in how these standards evolve.
  • Hydraulic Committee: Our hydraulic committee is developing a handbook on the Construction Auditor role in collaboration with the retail water authorities. This handbook aims to clarify and standardize the expectations for construction audits of water and sewer infrastructure in developments. Under the guidance of Adam King, the committee welcomes contributors who have experience with water authority audits. If you’re passionate about water infrastructure and quality assurance, reach out to Adam to help shape this important industry resource.
  • Electrical & Communications Committee: This committee has been focusing on the utilities side of development. A key update is that they have formally requested the reinstatement of the Harmonisation Committee. Many of you will recall that the Harmonisation Committee’s purpose is to align standards and practices across different power and telecom utilities. Reinstating it would be a big step toward consistent, streamlined electrical and communications designs in our projects. We’re hopeful for a positive response and will keep members updated on progress.

 

These committees are the engine rooms of our association – a big thank you to all the committee chairs and members who volunteer their time. Their monthly reports to the Executive have been invaluable in keeping our entire leadership informed and coordinated.


We’re excited to see these groups continue to drive improvements and provide technical leadership throughout 2025.


2024 Conference Success and 2026 Plans

Looking back, one of the highlights of last year was our 2024 ALDE Conference. The conference, themed “Connecting the Pieces: Crafting the Future of Land Development,” was a resounding success. We had robust attendance, insightful presentations, and great interaction among industry professionals. It truly served as a platform for sharing ideas and fostering connections. I want to thank everyone—organizers, volunteers, speakers, and attendees—who made the 2024 conference such a memorable event.


Building on that success, we are pleased to announce plans for our next conference in 2026. We have begun the early stages of planning to ensure it will be just as impactful. We’ll be seeking member input on topics and themes later this year. If you have ideas on what you’d like to see at the 2026 conference, we’d love to hear from you. Stay tuned for more details as we progress with planning – we’re committed to making the 2026 conference an even greater platform for learning and networking.


Growing Membership and Refined Benefits

Our association’s membership continues to grow, which is fantastic news. We’ve seen a healthy increase in membership over the past year, reflecting the value people see in being part of our community of practice. I extend a warm welcome to all new members – you’ve joined at an exciting time, and we encourage you to get involved and make the most of your membership.


With this growth, we’ve also been taking a close look at membership entitlements and benefits. The Executive Committee has been working on refining our membership packages to ensure that all members – get clear and fair value from their membership. This means clarifying what benefits you receive (such as event access, training discounts, resources, and voting rights) and exploring new benefits we could offer. For example, we are evaluating additional professional development resources and exclusive industry updates for members. Our goal is to have an updated membership benefits framework rolled out later in the year. As always, if you have suggestions on what would make your membership more valuable, please share them with us. Growing our ranks and improving member services go hand-in-hand to strengthen our industry voice.


Regional Growth and Networking Opportunities

It’s not just in Melbourne where we’re seeing momentum – our presence in regional areas is expanding as well. In particular, our Geelong and Gippsland regions have experienced notable growth in membership and activity. This year, expect to see more networking and event opportunities tailored to our regional members. We plan to host informal meet-ups, technical seminars, and networking nights in Geelong and Gippsland, providing forums for local issues and connections. Gippsland members can also look forward to a meet-up in the coming months to discuss development challenges unique to the region (such as rural drainage and coastal development considerations). By fostering strong regional networks, we ensure that no matter where you are – city or country – your association is working for you. If you’re based in these regions and interested in helping organize or lead local events, please get in touch.


Strengthening Governance and Data Security

Good governance is critical to maintaining trust and integrity in our association. To that end, we recently undertook an audit on member data security. With growing membership and increasing digital engagement, we want to make sure that all sensitive information – from your contact details to any payment info – is kept secure and handled in compliance with privacy regulations. The audit reviewed our data storage systems, website, and communication platforms for vulnerabilities and adherence to best practices.


I’m happy to report that the audit found our systems to be generally sound, with no major security issues. We did receive a few recommendations, such as implementing more frequent password updates and enhancing encryption in certain areas. The Executive is now actioning these recommendations to further strengthen our safeguards. Protecting member data is an ongoing commitment, and we will continue to review our practices regularly. Transparency is also important, so if anyone has questions about how we manage and protect your data, please feel free to reach out for more information. Overall, this governance initiative is about ensuring we uphold the highest standards of professionalism not just in engineering, but in how we run our association.


Diversity & Inclusion Initiatives

Our commitment to Diversity and Inclusion (D&I) remains strong. A diverse and inclusive industry makes us all more innovative and resilient. Over the past year, our D&I subcommittee has been very active. One notable activity was our participation in the RMIT Civil Engineering Industry Day. In collaboration with our YIELD (Young Engineers) group and the Education subcommittee, D&I helped host an interactive booth at RMIT’s event, engaging with the next generation of engineers. This was a great opportunity to showcase the land development field to students and to emphasize the inclusive culture we are fostering in our workplaces. We plan to continue such outreach at universities and career expos, highlighting that our industry is welcoming to all and offers exciting career paths.


Keep an eye on our events calendar for D&I events – all members are encouraged to attend and be part of the conversation. Whether you’re a seasoned manager or a young engineer, everyone has a role in shaping an equitable industry culture.


YIELD – Young Engineers Group

Our YIELD (Young Engineers in Land Development) group continues to thrive, and it’s playing a crucial role in nurturing the upcoming generation of professionals. Led by Kieran Ayres, the YIELD committee has been hard at work creating opportunities for younger members to learn, network, and contribute. By providing training in tools like ALDE 12d, we’re helping young engineers build practical skills that will benefit their daily work and career growth. The success of our self-paced 12d online course has shown the appetite for such initiatives, and YIELD plans to organize more technical workshops and maybe even site tours to complement it.


To our experienced members, I encourage you to support Kieran and the YIELD team – whether it’s by volunteering as a speaker at a YIELD event, or simply encouraging the young engineers in your teams to get involved. Our young engineers are the future of this industry and the association, and investing in their development is something we all benefit from. If you or someone in your office is a young professional not yet involved with YIELD, now is a great time to join and take advantage of the networking and learning on offer.


Looking Ahead

In closing, I want to touch on an important topic for the year ahead: clarifying the role of Registered Engineers in our industry. With the implementation of professional engineer registration laws in recent times, there’s been some uncertainty about how these regulations apply specifically to land development engineering. We understand that members have questions about whether certain design certifications or sign-offs require a Registered Professional Engineer, and how this impacts the way we practice.


We’re liaising with industry bodies and regulators to get clear interpretations, and we plan to publish a guidance note to help our members understand their obligations. Our aim is to ensure that every member is well-informed about the expectations and can confidently fulfill their professional duties under the new registration framework.


Overall, 2025 is shaping up to be a year of growth, engagement, and consolidation for our association. We will continue to advocate on your behalf, provide forums for knowledge-sharing, and deliver value for your membership. Despite any challenges that arise, I am confident that by working together and supporting each other, we will achieve great outcomes for the land development engineering community.


Thank you for reading, and thank you for being a part of our association. Here’s to a successful year ahead!

Coroner’s findings released for double trench collapse fatality near Ballarat


Members may recall the tragic news in 2018 of a trench collapse at a land development site near Ballarat, which resulted in the death of two men. The coroner has now released their findings into the death. Full findings can be found on the coroner’s court website; note that some may find the reading distressing.


The two men were standing on the side of the trench when the trench wall collapsed, burying the two men. One man died at the scene; the other was freed after several hours, but died I hospital the next day as a result of his injuries.


The coroner found that both deaths were preventable, and were the result of their employer’s “unsafe work practices”.


“This case serves as a reminder of the hazardous nature of trenching works and the critical need for employers to ensure continued compliance with their statutory duties under the law to eliminate or minimise risk to worker health and safety”


There were no specific recommendations made to avoid similar workplace deaths in future. However, we urge members to remain personally vigilant when they are on site in the vicinity of trenches, and to raise any concerns regarding trenching work practices with the contractor.

Melbourne Water updated their Guidelines and mandated their application in July 2024. The new document incorporated a number of minor tweaks and changes including an update to the rainfall across the region. The more significant decision was around the level of water quality improvement a sediment basin might bring to a treatment train. To read our whole analysis and recommendations click here


The latest MUSC guidelines builds on previous iterations of the guidelines previously issued

by Melbourne Water. The current guidelines came into effect on the 1st July 2024. ALDE have outlined the significant changes from the previous version of the guidelines (2018) and what implications the guidelines may have on water quality treatment assets and their sizing. The implications have been listed the items under “major implications”, “moderate implications” and “items to note” depending on the changes to the Land Development industry.


Major Implications

The removal of Nitrogen reduction in standalone sediment basins will impact current MW DSS’s which rely on several standalone SB prior to entry to waterway assets as part of the larger scheme treatment train. This will result in a shortfall in scheme treatment performance. It is assumed that this legacy item will be accepted by Melbourne Water and that further upsizing of wetlands to accommodate this shortfall will not occur in already gazetted PSP’s, however this needs to be confirmed by Melbourne Water. This was discussed during the webinar of presentation of the new guidelines; consultants have requested MW/E2 Design Lab to provide evidence (i.e. research paper etc.) of the rationale behind this decision.


The guideline appears to recommend the diversion of base flows within the model around treatment systems that are fed by pit and pipe networks. Clarification from Melbourne Water is required to confirm if this is a requirement or not as the wording given in the guidelines is unclear. This is a change from the previous guidelines where it was not recommended.


Given that majority of treatment assets constructed in greenfield areas are fed by the subdivision pipe network, the diversion of the base flows around the treatment assets impacts the performance of the assets, and will increase the treatment footprint required to meet best practice targets. Initial testing suggests that treatment sizing’s will increase by approximately 5% for constructed wetlands and may have similar impact on other treatment types. The increase in treatment area is exacerbated if a sediment basin is combined within the wetland node (see moderated implications), with treatment targets for TSS becoming the critical load reduction target. Based on some preliminary modelling, using one node to represent a constructed wetland (sediment pond + wetland) seems to lead to a more significant decrease in TSS and TP (rather than TN).


Rainfall templates have been reevaluated and modified:


  • An additional rainfall template has been added (“86224 Dandenong”);
  • the “Melbourne Airport” rainfall template has been renamed “86282 Melbourne Airport infilled” and the 10-year period considered has changed from 1971-1980 to 1987-1996;
  • the “Melbourne City” rainfall template has been renamed “86071 Melbourne Regional”, maintaining the 10-year period considered (from 1952 to 1961);
  • the “Koo Wee Rup” rainfall template has been renamed “87075 Bullengarook East”, the 10-year period considered has changed from 1971-1980 to 1990-1999 and part of the rainfall map has been amended (with the creation of the new Dandenong rainfall template);
  • the “Mount St Leonard” rainfall template has been renamed “86142 Toolangi”, maintaining the 10-year period considered (from 1995-2004);


Moderate implications

The guidelines provide clarity on when to model a sediment basin within the wetland node and when to model it separately within its own node, with the former having limitations with regards to representing bypass arrangements. Preliminary investigations suggest a reduction in 5% in treatment performance results when modelling the sediment basin within the wetland node. This will likely result in a larger grade separation between the sediment basin and macrophyte zone being selected in most designs to allow the sediment basin to be modelled as a separate node in MUSIC. This grade separation between the sediment basin and macrophyte zone will increase in most cases from the minimum 100 mm to 175 mm.


There is little clarity on how to model a wetland with two (or more) sediment basins under the assumptions that those are to be part of the same wetland node, but their outfall into the macrophyte area is at different locations. This is left with the consultant to decide the best approach and justify the rationale of the decision with MW.


Flows lost via infiltration in treatment nodes must be accounted as contributing to outflow pollutant loads. Majority of systems are generally lined so this is not applicable in most circumstances, however with infiltration systems becoming increasingly more common, this will be of more importance going forward.


Items to note

Based on the discussion at the Webinar presentation of the guidelines, it is understood that Climate Change has no or negligible impact on the water quality treatment for the different WSUD solutions. It is believed that further investigations should be conducted on this matter especially considering the latest AR&R 4.2 guideline advice regarding the impacts of climate change which are already affecting Australian catchments and its impact to exacerbate droughts and floods.


The guidelines explicitly states the requirements for wetland spells analysis. This advice is additional from the previous guidelines and provides clarity on the approach and requirements.


Noting that the pollutant concentration data, which is to be used if the user selects split surface model, has been updated from the previous guidelines. It is still recommended that mixed used nodes are used in most cases with the default MUSIC concentration data still recommended.


The guidelines provide no endorsement of proprietary devices or how to model such devices, it also states that such devices are not considered a replacement of nature-based solutions in DSS’s.


The section “version compatibility” acknowledges that the amended guidelines were prepared for MUSIC 6.3; however the underlying science of MUSICX is unchanged and the guidelines are applicable to MUSICX as well.


Flow routing is recommended for analyses that are sensitive to peak flows. These include flow rate diversions (for example, wetland high flow bypasses and pumping to stormwater harvesting assets), however avoiding the use of flow routing is considered a conservative (and probably the suggested) approach.


Bioretention systems are recommended to be modelled with and filter media hydraulic conductivity of 100mm/hr in MUSIC, which is the MUSIC default.


The Concept of TIA (Total Impervious Area)/DCI (Directly Connected Imperviousness) has been included in the guidelines, in accordance with the AR&R19. Use of TIA is recommended in order to avoid the potential of under-sizing drainage assets.


The new guidelines highlight how the treatment areas should be considered and represented in MUSIC as 100% impervious surface area to ensure that the direct rainfall becomes inflow.


Normal range and typical values of some zones outlined in table 2 of the guidelines still not consistent with fraction imperviousness values outlined in the EDCM.
