“We first learned of Accumulus through a main contractor. We contracted Accumulus to provide QS services on an 8 Unit industrial complex. I found him easy to deal with, prompt with pricing, very effective and have always been satisfied with the level of professionalism & service provided. We had some fire rating issues and his knowledge was very useful in suggesting an economical solution to comply.”
Flagship Developments Ltd
“Ive known Tony for many years. In that time he has shown himself to be a very competent and skilled project QS. Recently we employed Accumulus to compile extension of time and prolongation claims on two of my projects. It was the difference between incurring a substantial loss or obtaining a profit, I was very pleased with the claim detail and substantiation and both claims were negotiated successfully with very good outcomes. I have no hesitation to recommend their services.”
NTP Interiors Ltd
“We employ Accumulus to manage our commercial area, very satisfied with the contract reviews and dispute resolution and construction advice Tony provides . He knows how Main Contractors think and it has derisked our business and allowed our Project Managers much more time to focus on running our projects and installation teams.”
Insol Ltd.
“I have been working closely with Tony Davenport since early 2022. Initially, Tony provided a budget estimate for a $32M luxury apartment development. He then led the pricing and administration of the structural trade subcontract package, compiling budgets, letting trades, and professionally managing the package. Clearwater have since engaged Tony to complete the project and oversee Fitout, Services, and Landscaping trades. Tonys expertise are particularly evident in the field of high-end luxury apartments, and his ability to identify, procure and administer the required supplier, labour and subcontract packages for all aspects and elements of these projects is impressive. Tony has been invaluable, supporting the site team both onsite and remotely. I have no hesitation in recommending Tony for his Quantity Surveying services and expertise.”
