Client Testimonials

Mr. Shaun Peard

Mariswe / UWP

"UWP Consulting (Pty) Ltd was appointed by the South African National Roads Agency SOC limited, for the three sections of national roads.

As part of these appointments UWP Consulting were required to engage the services of a specialist sub-service provider to undertake the geotechnical investigations and provide specialist input to the location of and quality of material sources required for the project. In addition they were to provide specialist advice on founding conditions for structures and retaining walls. They were also required to manage the drilling contracts on each of the projects.

The primary criterion in selection of the geotechnical engineer, apart from costs, was the degree to which the service provider was able to demonstrate appropriate knowledge and expertise.

The projects are currently well advanced in the design phases and to date the service from Delta Geotech (Pty) Ltd has been excellent. Their knowledge and understanding of the projects and processes is evident in the manner in which they have managed their aspects of the projects.

We have no hesitation in recommending their services to you."
