If the contractor is unable to assess the structural conditions, they should:-
1. Decline the project:-
If they’re unsure about the structural conditions, they shouldn’t take on the project.
2. Recommend a specialist:-
Suggest hiring a structural engineer or expert to assess the conditions before proceeding.
3. Conditional warranty:-
Offer a warranty conditional upon a structural assessment being done and any issues being addressed.
4. Limited scope:-
Limit their scope of work to specific areas or tasks, excluding any work that requires knowledge of structural conditions.
5. Collaborate with experts:-
Work with a structural engineer or expert to assess and address any structural issues before waterproofing.
Remember, a reputable contractor prioritizes safety and effectiveness over profit. They should never guarantee waterproofing success without knowing the structural conditions.
