We recently used the services of Bidding Reliable to price up the carpentry sub-contract package for 16 units in Brisbane. Initially we were unsure if this would be worthwhile, but when the estimate came back, it was spot on. Details of the estimate were clear and understandable and we could easily see how all the costs were calculated. We won the tender and will definitely be using Bidding Reliable from now on. You have to be able to trust your estimator and I trust Bidding Reliable.

As a civil contractor we could be tendering on a multitude of projects at any one time. Timing and accuracy are crucial in this economic climate. We have used the services of Bidding Reliable for a number of projects and as a result have been able to streamline our processes and ensure a higher degree of accuracy. Even when it looked like we couldn't meet the estimated prices a quick phone call and we had a solution and all the answers we needed. Bidding Reliable is up to date with current market conditions and is now a valuable part of our business structure.
Dermot O'Dwyer
Sundown Civil, Sydney
Bidding Reliable provided us with assistance for a large civil construction project. As an International Construction Company, local knowledge was vital. Bidding Reliable assisted us with local market conditions entailing materials pricing, wages, office staff, project managers and subcontract packages, as well as advising us with business structures, licensing, taxation and more. Someone was always available to discuss our needs and had reliable, detailed solutions to all situations. We have no hesitation in recommending Bidding Reliable to anyone. We have no doubt that they will be as satisfied as we have been with the service they will receive.

Shafa Contractor & General, Cairns
Bidding Reliable provided us with a BOQ for a small duplex development here in Mt Isa. This enabled us to get materials shipped direct from Brisbane saving both time and money. Turnaround time was fast, detailed and accurate. What more can you ask for? I will be using them again on our next project.

Mt Isa, Hobart
As an owner builder for a new straw-bale home in Melbourne, we needed a building estimate for finance. After searching online, I contacted Bidding Reliable . I received a reply to my query within minutes. Everything was upfront, concise and professional. The cost to do the estimation was also reasonable. I received the estimate on the promised day, first thing in the morning. Communication was topnotch and we received a complete and thorough estimate. Suffice to say, we got our finance using the building estimate we received without needing to change a thing. I can't praise Bidding Reliable enough. Above all things, honesty is paramount when doing business online. Bidding Reliable gave us a peak into how they've built a successful business. I highly recommend you get in touch with them, you'll be as impressed as we were.
