Our People

Kader Gaidien - Director in charge of all technical aspects including site management, occupational health & safety, production, quality control, and workforce management.

Kader, 40, is a carpenter by trade. Having trained at Slingsby & de Jager as an apprentice and then gone on to manage numerous building sites during his 10 year tenure at Slingsby & de Jager, Kader accumulated the necessary skill and experience required to procure and manage diverse building contracts efficiently and effectively. His calm demeanor and cautious air has proved invaluable in bringing contracts to their timeous conclusion, while an exacting professionalism and “get it right first time” philosophy helps to minimize defects when handing over contracts.

Kader is also in possession of a National N3 Certificate in Industrial Electronics.

John Slingsby - Commercial Director in charge of administration, business procurement, tendering, cost control, marketing, and contractual issues.

John is a qualified Quantity Surveyor from UCT. After working as a site contract surveyor abroad, he returned to South Africa to join the family firm of Slingsby & de Jager. During the ensuing 8 years, John & Kader worked together on many successful projects, forging a strong and mutually respectful bond of friendship in the process. They soon realized the inherent power of their professional compatibility; their combined ability to deliver a quality project – due in large part to Kader’s experience – which remained within budget – down to John’s skills as a QS – enabled them to continuously delight their professional teams and guarantee client satisfaction.

Our Humble Beginnings

It was during a brief separation in 2003 – while John took up a position at GVK Siyazama Building Contractors and Kader embarked upon some minor local building works – that the latter broached the idea of starting their own company, one based on the principles and professional ethos of their mutual former employer. Slingsby & Gaidien was subsequently formed in 2004, finally enabling John to make good on his commitment towards restoring his grandfather’s professional legacy. And in the short years since their inception, Slingsby & Gaidien have gone from strength to strength, completing over 30 contracts with a combined turnover in excess of R 60 million as per the results for financial year ending February 2010.
