We cannot recommend BIM Projects highly enough for their construction services. From the initial consultation to the final touches, Kane and the team exhibited professionalism and expertise. Their attention to detail and commitment to quality were evident in every aspect of the project and the result exceeded our expectations. Their communication was excellent; they kept us informed at every stage, ensuring a smooth and stress-free experience. The team’s punctuality was remarkable, and they consistently met deadlines without compromising on the quality of work. Moreover, their trustworthiness was evident from day one, giving us complete peace of mind throughout the construction process.

Kane and his team were awesome throughout. Highly organised, highly skilled, professional and they did a high quality job in the time frame estimated.
The finish on everything they did was very high. They were also all friendly, fun guys to have on site, and were excellent to work as a team with throughout. We’re stoked with the final result.

They say you should never go above 100%, but I am willing to say I trust BIM Projects 101%! They came in on time and under budget. The work was done to a high standard which to us was very important. Not to sound corny, but this was the best tradie experience we have ever had as home owners.

I chose BIM Projects Ltd to do an initial on site review and quote. They were a great bunch of people and you could tell they had worked on a few projects together, which was a big help.
We discussed with BIM Projects Ltd which order we wanted to do the bathrooms in, and decided it was best to start with the main bathroom, followed by the ensuite.
How do you feel about the end results?
“Awfully happy,” Dave says.
Anything we saw that didn’t meet our expectations at the time was rectified straight away.
Everything was kept clean and tidy around the site, and as a result the bathrooms are in a really great condition — and they look great too!

Kane and his team were excellent to deal with from start to finish. Kane put a lot of effort into understanding what we were wanting and whilst his quote wasn’t the cheapest, it was fair for the quality we received.
His builders were super professional and helpful (and friendly which was an added bonus) and the plasterer was super fast. He also organised an electrician super last minute who was great.

Kane and his team are friendly and reliable, they do a great job and Kane always lets us know if the weather or anything else is going to cause any delay. BIM Projects are everything we look for in a building company.
