Over the past number of years Mark has collaborated with us on a number of technically challenging concrete projects in the mining, petrochemical and defence aviation sectors.
Many times the intended performance requirements were not clearly indicated in the project specifications and the prescriptive requirements conflicted with the intended performance. In resolving these issues, Mark’s collaborative approach was evidenced in working with us and our customers in developing fit-for-purpose concrete mix designs that met with the functional requirements for the hardened concrete whilst optimising value for money outcomes for our customers.
In addition, Mark has assisted us in relation to the subjects of source material selection, autogenous healing of concrete, defects investigation, mass concrete pours and thermal control plans, construction methodologies, concrete batch plant establishments and finishing & curing techniques.
We greatly value his opinion on a range of matters — an opinion underpinned by over 28 years’ experience in the Australian and South African construction industries — and his ability to provide timely, objective and robust technical advice that stands up to scrutiny and counter argument, and protects our interests.
His considerate and likable persona fosters excellent and trusting relationships with clients and his colleagues and peers alike.
We look forward to working with him again in the future.
