International Conservation Services

International Conservation Services engaged DY Constructions to refurbish our premises in late 2020. DY provided outstanding service from the very beginning, for what was undoubtedly a difficult job. Firstly, the refurbishment had to be undertaken over a 4 month period while we continued to work in our laboratories and offices. Jason Frawley’s superb project management meant that our staff had clear timelines for which to plan their work in alternative spaces. In many instances, half of the lab was cordoned off to allow DY to work in the other half. Jason’s meticulous coordination of a wide range of contractors (including builders, painters, electricians, and other contractors not directly working with DY) was the foundation of our on-time and successful outcome. Secondly, DY had to take into account our need for extreme care of sensitive equipment and client items. This was achieved with minimum concern on our part, and DY was very responsive to our requests throughout the project. We were also impressed with the caliber of DY’s subcontractors, in particular Serge, the head builder. Serge was efficient, attentive to detail and careful. We really appreciated having someone on board who obviously cares about the quality of his work, and who could develop good working relationships with everyone in the building. This is particularly important when a project runs for such a long period of time. We were also pleased with Jason’s excellent guidance about options. It helped enormously to have his expert advice and eagle eyes on project planning and progress. If we ever need another refurb, we’ll definitely be talking with DY.

International Conservation Services reference for DY Constructions


It is with great pleasure that I write this letter of recommendation for DY Constructions Australia Pty Ltd, 

We have involved DYC for the fit out works of our new retail and office space, Cosentino City Sydney located at One30 Hyde Park, Elizabeth St, Sydney CBD, as main General Contractor We have contacted different as, but DYC was the most professional during the bidding process and Jason Frawley and his team, they inspired us enough confidence, and we were not wrong in our choice.

DYC has exhibited skill, quality workmanship and responsiveness throughout the near 6 months of the project. It has been a not easy project because of distance, Coved-19 pandemic, travel restrictions and other challenges that we faced during the construction works. Despite of that Jason has stuck to a very demanding schedule and he was leading the whole process with success. A great compliment for any trade contractor is the fact that I have counted on them anytime I need some support from him to deal with other contractors. 

Based on my experience in working with them, it is without reservation that I would recommend DY Construction and Jason, be considered on any construction project that you may be pursuing. 

We will count on them for our expansion strategy in Australia.

Consulate General De France Sydney

This is to certify that the Consulate-General of France recently employed the services of DY CONSTRUCTIONS to carry out renovation works in part of the premises. 

The initial quotation was presented by Dmitri Kolontaevskii in a very professional manner and he was open to further discussions and offered solutions so that our fitout corresponded to the budget allocated by our Authorities. 

Dmitri’s team carried out the works with minimal disruption to our day to day activity and were always accommodating. The team was always punctual, efficient and the finished outfit perfect. 

We will not hesitate to call on them again should we require further building works as we are very appreciative of the excellent quality of their services.

My company, C.R. Kennedy & Company Pty Ltd, is the owner of an office tower comprising of approximately 10,000 square meters of office space located at 15 Bourke Road, Mascot.

We have approximately 15 different tenants throughout the building. Often older tenants are moving out and new tenants are moving in, which requires frequent building works; in addition to this there are also regular general building upkeep and maintenance jobs. 

DY Constructions Australia Pty Ltd have been engaged by my company to undertake several fit-out, refurbishment, and removal projects throughout our building. 

Each time we have found that DY Constructions have always completed work of the highest standard, and DY Constructions have finished all jobs within the forecast budget and in accordance with set timelines.

On behalf of Richland Brands. it is with great pleasure that I write this testimonial for DY Constructions. 

Initially we contacted 3 different suppliers (including DYC) for initial discussions and to rough out a budget for a 334sqm office fit out. DYC was far and away the most professional in so many ways.

Dmitri and his entire team were amazing in every aspect. From the initial design stage to the final fit out and everything in between. I was very impressed with their knowledge. dedication and attention to detail. They were constantly in communication with us so we knew what to expect and when. No request was ever too difficult.

The tradesmen were outstanding. highly skilled and they went out of their way to go the extra mile. They left the premises neat and tidy each day. 

DY Constructions are a fantastic company to work with and I would have no hesitation in recommending them to any business seeking a professional and creative fit out of their office space. They will deliver a quality result. on time and on budget. Their excitement is absolutely comforting as they share your enthusiasm and excitement throughout the whole project.

As my boss said on several occasions. “DYC are rock stars!”. 

Yours sincerely

Richardson & Wrench Elizabeth Bay

We are the executive committee (elected owners) for a building in Waterloo with 150 apartments plus 30 commercial/offices spaces. Recently we decided to upgrade three foyers ( two residential and one commercial ) in the 180. lot building. Doing this is a mammoth task because it requires all owners to vote on said designs. raise funds and also pick quotes. DY Constructions were one of several companies that tendered for the work and it was from that moment we noticed their biggest difference. 

From day one, DY were attentive to every matter and patient dealing with many different questions regarding their quote. They always sounded caring and took the time to break down every thing in detail. We then moved to accepting their quote which was another huge task. Liaising with 150 occupants about access. clearing, changing entrances, setting up safety measures along with so many other items we as a building had no idea about DY were all over it! 

The works began on time as scheduled. however like any renovation there are speed humps and many moving pieces of which DY cleverly maintained throughout the entire process and not once was anything too hard. When it would rain, they would simply start something else, when there was a delay due to council, we moved items around in the calendar to better suit and just like that the job was completed ahead of schedule. 

As it came to the end of the job, it was clear what we envisaged came to life and DY were mainly to thank. Nearing completion we decided to proceed with some additional works which DY competitively quoted. When it came to this task there was such items where DY were able to pull back some costs by wisely using other material already sourced throughout the renovation. 

Finally customer service but more importantly attending to issues in real time is huge to us and we’ve experienced over the years that some trades are slack with this. This is another reason why we highly recommend Dimitri and his team. 

To close, we would highly recommend DY for any job. big or small as they are clearly able to handle the task at hand. You’re welcome to call one of us as committee members to ask any questions. 

Best of luck with your renovations and be sure to give DY a go!

DY Constructions were a dream to work with. All of the trades people completing our renovation genuinely cared about the job they did and gave us a brilliant outcome. Our staff were really impressed with how collaborative they were catering for us working throughout and Dmitri was constantly in contact, clarifying and communicating so we always knew what was happening. We have now booked them for more work. I can absolutely recommend them.

Henty House

DY Constructions rebuilt our foyer at 379 Kent Street Sydney in April 2020. We went through a detailed bidding process and obtained quotes from 5 different builders. DY Constructions submitted a highly competitive and detailed proposal. DY Constructions also did in-house plans which saved us money in not having to engage an architect. The project was delivered on time and within budget. A special thank you to their project manager Jason Frawley. He was fantastic and kept me up to date throughout the project. I would highly recommend DY constructions for any building project in Sydney. DY Constructions have definitely earned a 5 star review!
