We are a client using the NEC3 Engineering and Construction Contract (ECC) Option C (target contract with activity schedule) in Hong Kong and are considering using NEC4 ECC Option C. To meet legal requirements, employers must take out insurance to cover their liabilities under the Employees’ Compensation Ordinance and at common law for injuries at work. We consider the premium is covered under item 13(i), ‘meeting the requirements of the law’, of the schedule of cost components in NEC3 ECC Option C, so it is part of defined cost. However, in NEC4 ECC Option C, item 13(i) only covers ‘contributions, levies or taxes imposed by law’. Does this still include the premium for employees’ compensation insurance?
