Project Definition Close co-operation with the customer, at all stages of the project definition and preliminary design, is required before De Smet Engineers & Contractors (DSEC) can effectively start work on a project. Such dialogue with the end-user or client is essential in order to eliminate uncertainties and unknowns, thus avoiding overruns, extra expenditure and unforeseen delays. Especially in critical areas such as local construction works, DSEC’s experts will exercise full control on preliminary investigation and studies to ensure that the Full Responsibility Concept is guaranteed. Accurate budgets are often commissioned by DSEC’s customer with a view of checking project feasibility study hypothesis.
