DevCon project delivery across sectors

Trusted by leading organisations.

You demonstrated a willingness to assist at all times, working with the wider team to resolve the inevitable challenges posed by the building, design, technology, program and procurement. Refreshingly, Devcon professionally dealt with many issues without seeking time or cost variations. Workmanship and quality was high, defects minimal and site safety exemplary. Throughout, communication was solid and reporting clear and timely. Your site and office team were a pleasure to work with and made this project more enjoyable for all concerned. It is easy to dismiss fitout as the poor and simpler cousin of new build construction. However this would be an error. There are subtleties and fine detail in fitout that can defeat construction companies that fail to make this distinction. My faith in Devcon's ability to not only recognise this distinction, but to act accordingly has been paid off in full. Well done and thanks.

Max Thomson DirectorSpitfire Control

During the course of the past three years, Devcon has completed a number of projects for the Perpetual group of companies including, making good obligations, partial refurbishments, new tenancies and the preparation of tenancies for sub-leasing. In each instance, the respective project was completed on time and within the budget previously determined. The Devcon team promote and deliver a collaborative process for all issues encountered during negotiations with their client, adjacent tenant, consultants and statutory authorities. Devcon are true to their mantra of "Focusing on Solutions" and we would recommend them to any potential client.

Peter Jervis Senior Manager, Building Support ServicesPerpetual

On behalf of Snowy Hydro, I would like to extend our sincere thanks for the excellent work you and the DevCon team delivered in bringing our new office fit-out at Grosvenor Place to life. It's evident that you took a collaborative approach with Greenbox and Spitfire to ensure the design intent was fully understood and translated into a practical, functional and well-built space. Your attention to detail and steady execution of the build were instrumental in achieving the high-quality outcome we're enjoying today. I'd also like to acknowledge your efforts in completing the fit-out not just on time but also within budget which is impressive, especially given current market pressures. This clearly demonstrates your professionalism, commitment and drive you brought to this project each day. Not surprisingly our new office space has been extremely well received by our people. The quality of the finishes, standard of workmanship and overall cohesiveness of the space have all contributed to an environment that looks and feels professional, contemporary, welcoming and truly fit for purpose. Thank you again for your diligent efficiency and partnership throughout this project. We are extremely pleased with the outcome and grateful for the role you and your team played in constructing a workspace we are proud of — overall a tremendous effort and an outstanding result!

Dennis Barnes CEOSnowy Hydro

In August 2012 we engaged DevCon to completely refurbish our Head Quarter's reception in Rydalmere, Sydney. The facility is some 35 years old with a number of age related issues and the reception project needed to be completed for a VIP visit in early September. From the outset, we were impressed with Ray Glavinovic's professional conduct and responsiveness. Ray was very customer focused and flexible in working with us, ensuring that our requirements were always met. We were particularly impressed by his crisis management ability enabling the successful delivery of our reception project. We have no hesitation in recommending DevCon to anyone with similar project requirements.

Jeremy Needham Executive DirectorMitsubishi Electric
Peter & Kirsty Gold

Ray project managed the construction of our architecturally designed home. His role was crucial to the successful completion of our large and complex project. He has a wealth of commercial building experience that enabled him to provide creative practical solutions to complex building issues. He uses thorough project management and documentation processes. He is extremely flexible and adaptable and able to fill gaps in the building process as required. He has an excellent commercial approach to building contracts and costs. This along with his keen financial attention to detail benefitted us with building sub contracts. His biggest asset is his people management skills which were exceptional. He was able to engage, direct and manage both the builder and ourselves to achieve constructive outcomes. He was professional, calm, responsive, action orientated and logical at all times. There is no doubt that he had a huge positive impact on the cost, quality and time line of our project. We have no hesitation in recommending him.
