We have known and have worked with Chris Venter for well over 20 years. On all projects undertaken with Chris, we have found him to be extremely pro-active and intensely thorough with all tasks at hand. The above traits and his ability to ensure budgets are met have made for remarkably successful projects over the last many years, across the entire spectrum of the building industry. Chris’s adapt or die attitude has held him in good stead.

Conner KinsellaFlagstone

I have worked with Chris over many years completing a number of successful construction projects together. Chris has proven to be professional and talented in his duties as a Quantity Surveyor, Project Manager and Principle Agent. I have come to admire and respect Chris for his work ethic, honesty, and high standard and quality of service. Chris is a stand-up guy and a great asset to have on the professional team. I value our continued association with him and Cornerstone CBS.

Martin LewisonHLArchitects

I have had the privilege of working closely with Chris Venter, both in his early career and more recently as Cornerstone CBS, for the past 14 years. Literally dozens of projects undertaken for the Imperial Group/Motus took us to all parts of South Africa and Namibia. With Chris initially providing a Quantity Surveying service and growing into an additional Principal Agent role through Cornerstone CBS in recent years, these projects were managed and completed with great success, in most cases with significant savings to the Client.

I have worked closely with Chris Venter on key development projects in the past and have found him to be thoroughly knowledgeable and innovative in his approach.

I would certainly recommend Cornerstone CBS and Chris, in particular, to anyone embarking on a new project that requires superior Quantity Surveying and Project Management skills!
