An important driver for including Environmental Soil and Water Quality work in our recommendations is that in our experience little influence can be exerted over environmental legislation and regulations, but that the way in which these are integrated into daily practice can indeed be managed. By taking the intended developments as a starting point and adjusting them from there to laws and regulations, there is much to be gained! By applying research and advice in the right way and at the right time, CRUX ensures that unnecessary work and stagnation in the execution soil excavation and-or groundwater pollution/sanitation are prevented. This significantly reduces construction costs and minimizes the risk of delays. CRUX can be of service from the initiation phase through the realization phase of a project, including the following recommendations and research.
