Erecto Construction Co. contracted to build an office building for Owner. Without Owner's consent, Erecto delegated its duty to do the excavation work to Gopher Inc., a subcontractor. The excavation work is standard, nonpersonal work that does not require any special skill. Gopher failed to do the work properly. 1. Was Erecto legally entitled to delegate its duty to do the excavation work to Gopher without first obtaining Owner's consent? 2. Is Erecto liable to Owner because Gopher failed to properly do the work?
