Only architects and engineers that know their liabilities can make arrangements to avoid them and prepare themselves correctly. The reason for architect and engineer liability rules form the so called joint and several liabilities of all involved parties.
The planning and controlling construction engineer is liable for defects. Also, the executing company which worked on the defect building is liable.
Additionally case law demands extensive advice- hint- and control duty by an expert.
Tumescent conflicts with noncompliant building owners are a time-consuming undertaking for an expert as mentioned above. Disaffection is reflected in detention of fee claims.
