“We formed a relationship with Stack Masula, who were able to bring into our company the latest and compliant WHS system that fitted our operation. The system contains Management Systems, JSA/SWMS and all the necessary site and field staff needed. In this time we have had three major external audits. From these audits, we received only minor non compliant issues that were corrected either straight away or within a few days. In general, the auditors were impressed with our system because it was not a rubber stamp OHS system, it is an industry type system that covers everything needed. We have been very happy with our relationship with Stack Masula and hope to continue the relationship for many more years.”

“We have partnered with Stack Masula for over 10 years. Having achieved the significant milestone of attaining SAI Global certification to Quality Standard ISO 9001, WHS ISO 4801 & Environmental ISO:14001. I’d like to sincerely thank you and your team for your assistance and ongoing support. When we initially engaged the Stack Masula team, our company was a small contractor struggling with compliance  and Safety culture issues within our constructions teams. The educational support, document development and focus on continued improvement now sees our company being engaged regularly by tier 1 construction companies and some of Australia’s leading miners. I am proud to say that I believe our company is an industry leaser in WHS practices and a huge focus in our day to day activities. The culture within our team hs turned around significantly, and whilst we continue for constant improvement we will also continue to rely on the trusted advice of you and your team.”

“Groundworks Australia has been using the services of Stack Masula since 2006. Initially they helped us construct and implement a Workplace Health and Safety Management System that perfectly suited the unique nature of our business.  We have since had the opportunity to test the robustness of the plan through our need to gain entry to mine sites that traditionally expect extremely high standards of safety from their subcontractors.  On many occasions our WHS submissions have been commended for their professionalism and thoroughness by the site safety personnel.  After having gained confidence with our safety systems, we decided to attempt ISO9001 certification.  Again, we worked with Stack Masula to formulate a comprehensive Business Management System and again they put together a set of documents that both comply with the standard and allow our business to function easily, efficiently and at the highest level of quality.  We successfully achieved our goal of certification at the end of 2010.  To this day, Stack Masula remains an integral part of our compliance program by providing ongoing advice and auditing services throughout the year.  Groundworks would unreservedly recommend Stack Masula to oversee any WHS or Business compliance system and suggest that the investment is invaluable.”
