VelWa advice

Another aspect of VelWa is advising companies (steel construction, contractors, engineering firms) to apply correct conservation (read steel protection) for new projects to be built, but also to advise on repairing a conservation. These recommendations are of a very limited nature. For example, for repairing the preservation, research is first conducted into the reason for, for example, the failure of the preservation. This can vary from incorrect pre-treatment, incorrect paint system, to advice for conservation before renovation. Below a number of examples from 2019:

– Repair of fire-resistant coating preservation at parking garage and office building
– Advice on preservation for renovation of the awning of an office building
– Advice on the conservation of a number of bridges in a park
– Use of fire-resistant coating in a hotel
– Investigation into the status of conservation on a steel structure of a hall, in connection with possible takeover of the building
– Advising associations of owners to come to an amount for service costs for maintenance
