It’s the classic tale of two cities. One city is occupied by architects and engineers. The other, by contractors. And while the cities typically co-exist relatively peacefully together, at times, they do not, such as when a defect arises that can either be a design or construction defect.

Sometimes, project owners are pulled into these fights as well. There is a common law rule that when contracting with a contractor the owner impliedly warrants to the contractor that the plans and specifications are sufficiently accurate and correct.

And, if you work on local public works projects, you may be familiar with Public Contract Code section 1104 which provides that, with the exception of design-build projects, local public entities cannot require a bidder to assume responsibility for the completeness and accuracy of architectural or engineering plans and specifications.
