    To whom it may concern,

    Big River Developments has been the winning tenderers for the past 2 major extensions/renovations at The Renmark Club in 2007 and 2012. Both of these projects were technically difficult and had strict tlme frames to adhere to.

    Both extension/renovations were extremely well organised and we were kept informed of the progress and scheduling of the build the whole way through. As we had to continue trading during this time, we were in regular contact with the supervisor and managing director about any possible noise /power disruptions and BRD were able to minimise the impact on the Renmark Club's staff and its patrons.

    Due to the scope and nature of these extensions/renovations there were variations to the contract which were dealt with promptly.

    On the 2012 build, once demolition had commenced there were some significant structural defects picked up in the existing building, these were missed by the architect and the engineer. After consultation It was decided to demolish the club further and to do a significant amount of new steel, concrete and roof structural work (200m2 plus). Throughout this period while waiting for the new design and engineering, other work continued and somehow the building project was still completed on the original timeframe specified even though there was a 6 week delay in getting new documents.

    These 2 projects totalled more than $6 million and the finish and functionality are a true testament to Big River Developments professionalism and workmanship. The Renmark Club has used Big River Developments for many other smaller projects as well over the last 10 years and they have always been more than happy with their work.

    The Renmark Club highly recommend Big River Developments for any building work requiring a high level of professionalism, attention to detail and with the knowledge they are a very well organised and structured company to deliver projects in an appropriate timeframe.

    We have had the pleasure of working with Big River Developments on the Berri Hospital Redevelopment Project. Murray Knowling and his team were engaged by us to carry out numerous works on this project including block laying, carpentry, door installation and tiling. Having a high level of competent administration and excellent lines of communication made dealing with Big River an easy task.


    Coordination of works onsite was of a high standard as well. Their site foreman Dave Smith had the heavy task of coordinating various trades and was able to do this while meeting program deadlines.


    I take great pleasure in providing this reference for Big River Developments and would be glad to recommend them for future projects

    Renmark Paringa Homes for the Aged Inc which trades as Renmark Paringa Independent Living operates 93 independent living units on 16 sites at Renmark and Paringa. We have had an association with Big River Developments and its principal Murray Knowling for about the last 12 years.

    Since 2008 Big River Developments has successfully tendered for three projects of $1.25m each. These projects consisted of six units for a total of 18. As well Big River Developments successfully tendered for a further $400k 2-unit project.

    These projects were completed in a timely manner in accordance with contract conditions, specification schedules and within budget. Workmanship has been of a high standard and has met all building code standards.

    Murray Knowling has always been approachable both by telephone and at very regular site meetings. He has been consistently willing to discuss technical matters, variations to contract specifications and progress with the build.

    We have found Murray Knowling and his staff to be courteous and obliging in all dealings.

    Kevin Merritt, Chairman



    I would like to thank you for the manner in which you have undertaken the above project and the large contribution you have made to its success.

    In relation to contractual matters, you have been consistently fair and offered solutions to conserve expenditure. As a result, the project has come in under budget, the units were delivered on time.

    Your willingness to go out of your way to liaise with potential and incumbent residents has also contributed to the success of the development.

    I look forward to working with you on future stages and hope we have an opportunity to do the same on other projects.

    Yours faithfully

    Simon Drew, Managing Director



    Thank you for your work on the Barmera Retirement Village Expansion, which included the construction of 10 additional units at the Bruce Road site.

    It was a pleasure to work with you and we look forward to you again tendering for available work.

    Once again, thank you for your support of the Riverland Regional Health Service.

    Nino DiSisto, CEO Riverland Regional Health Services



    Please accept this note as a token of our sincere appreciation and thanks for the work which was undertaken by Big River Developments in the alterations and additions to the Council office located at East Terrace, Loxton.

    The co-operation received and the manner in which you and your sub-contractors conducted the building work under difficult circumstances has been greatly appreciated. We realise how difficult it must have been to undertake your work whilst still helping us to maintain an operable office location.

    The co-ordination of all the work was tremendous, coupled with the support of the bricklayers, carpenter and joiners, electrician, plasterers and painters, airconditioning mechanics, carpetlayers etc. enabled the project to reach practical completion in the time frame as originally predicted.

    Yours faithfully,

    T.L. Burgemeister, District Manager
