Who provides the burden of proof according to the Buildwise implementation method (WTCB)?
Many construction promoters and contractors too often impose on my clients the burden of proof of Buildwise (WTCB) in the event of a dispute about implementation and permitted deviations!
Let's be clear!
My clients are not members of Buildwise, nor do they have any knowledge of it, nor any obligations to know or fully know it, let alone consult it (they also have no access to this detailed information)!
It is up to the building promoter and contractor to fully know or consult them and not the other way around... they build... and they are the professionals... and they are members of this organization, and in the event of disputes they can only appeal do on Buildwise...and not my Clients!
List of execution methods
Buildwise (WTCB) part 2
On a slightly sloping terrain the situation is comparable to the 'accessible' details (see detail no. 4.1, TV 264 p. 58), where the watertightness of the buried part is ensured by means of a membrane with welded or glued seams that is raised above the highest level of the paving or the earthing around the building.
Rainwater drainage
Every household produces waste water. Just think of the water from the sanitary installation, from the kitchen, from the washing machine, ... Domestic waste water must be purified throughout Flanders.
Rainwater from your roof or other paved surfaces is best left on site as much as possible. You can reuse it or let it infiltrate into the soil. Do you still have to dispose of it? Then keep the rainwater separated from the wastewater.
