About Us

Who we are

ViKO was founded in 2009 by Hannes van Dullemen, and is based in Midstream, Gauteng. ViKO’s aim is to utilise their expert knowledge and extensive experience gained in the food, beverage and other industries to provide an engineering service that considers and addresses the client’s complete requirement in order to provide the desired solutions and improve its operations.

A key focus for ViKO engineers is the understanding of the client’s process flows and plant operations. It is critical to properly communicate and define requirements from the start in order to detail concepts and designs, do proper planning and ultimately have a successfully completed project.

ViKO can add long term value to an organisation through technically sound solutions, their existing experience and expertise in various fields, customer focussed mind-set and alignment with the client’s organisational objectives.

From our experience in the telecommunication, food & beverage industry we realised that there exists a large communication gap between the client and existing available civil & structural engineers. Furthermore, structural engineers do not necessarily understand the time, economic and access challenges faced by the client's engineers to construct structures, buildings and supporting infrastructure. The aforementioned can cause delays during the pre-tender phase due to details that need to travel back and forth for reviews and this ties up the client in details that should be provided by an 'expert'.

Further, Civil & structural engineers should know and understand the client's principals regarding processes and flows of a plant set-up.

All document and drawing plan production are done in-house. The use of 3D packages have become the norm in modern day engineering design and analysis, 2D applications however will never be obsolete and ViKO utilises both type software systems.

Engineering Software packages such as AutoCAD and Autodesk Revit are used on a continuing basis. From an engineering design and analysis perspective we utilise the South African developed software package PROKON for all structural and finite element analysis.
