451. Extent of authority as agent.

The objects for which an architect or engineer is employed comprise the preparation of drawings and plans for the buildings or works in contemplation, and also the supervision of their construction, and he generally is the agent of the building owner or employer in both these respects1, although his authority in dealing with the contractor may be limited by the terms of the building contract2.

With regard to drawings and plans, although the architect is the agent of the building owner, he has no implied authority to warrant that they are correct, or that the work can be carried out
