From the onset Alder maintained great communication from the Estimating Manager handover to the Project Manager with so many items and details to be resolved and the staging of the works in a live environment. Alder's site team maintained open lines of communication through daily, weekly and monthly meetings to create "business as usual" experience for Xanadu Apartment residents and visitors.
After the initial site pre-starts and safety audits our team were not required on site daily as the Alder management systems were in place steering and ensuring the successful completion of the works. Alder delivered the project on time with staged handovers, and exceeded expectations in solving design issues resulting in cost savings. If you are seeking a construction company that can partner with the Client and deliver high quality work, transparency with integrity, professionalism, I can recommend Alder.”

During our tender process, which included 17 competitive bids, Alder Group stood out due to their outstanding reputation and the impressive quality of their tender proposal. Their pricing was competitive and their responsive service made a significant difference in our decision-making process.
I have absolutely no regrets about our choice to partner with them for this project. They adhered to the project timeline and remained within the approved budget, which is a testament to their efficiency and commitment to delivering results. Throughout the project, Alder Group maintained open lines of communication, keeping us informed despite the numerous challenges we faced along the way. The quality of their work is nothing short of impeccable and we are extremely pleased with the final outcome.”


I can recommend Alder as having the people, systems and experience for similar work in the future. I was impressed with the level of dedication and attention to detail from your Senior Management Staff demonstrated with the management of their consultants, sub-contractors and suppliers during delivery.
A number of challenges associated with the precast concrete components and stainless balustrade were overcome by your Construction Team and I thank them for their proactive approach to offering up practical solutions to deal with the range of issues that were present during delivery. The City of Gold Coast has received a very well-built facility that was delivered with a high quality finish that reflects well on the whole team.”

As a flagship learning facility, the intricate and innovative design required a high level of quality and attention to detail, which Alder was able to deliver to an exceptional standard.
This project presented challenges being in a live primary school environment adjacent to the main pick-up and drop-off zone and Alder performed their works maintaining a high level of safety while ensuring minimal disruption to College activities. The team were dedicated to keeping the project on track and worked extremely hard to complete the project within the required timeframes.
This building has won multiple awards with Alder attaining the 2018 Master Builders Award for Education Facilities up to $10 million, which attests to the level of workmanship, professionalism and quality to be expected from Alder.”


Their unwavering commitment to providing high school students with a tangible understanding of potential career paths within the construction industry, through the Building Blocks Program is truly commendable.
What truly set this initiative apart was the personalised mentorship that the students received. The professional tradespeople not only demonstrated technical skills but also shared personal anecdotes of growth within the industry. This humanised the construction sector, making it relatable and inspiring for the students.
The impact of this experience extended beyond the construction site. Conversations within my classroom transformed, as students engaged passionately about the trades they had encountered. Many discovered latent talents and aspirations they had never considered before. Witnessing this growth was a testament to Alder's visionary approach, which not only broadened their career horizons but also contributed to their personal development.”
