In case entitled Greg Opinski Construction v. City of Oakdale (Cal. Ct. App. October 6, 2011) a California Appellate Court held that when a public works contract requires notice is given as a condition for getting an extension of time and notice is not given the contractor cannot later claim that the delay was caused by the public entity. This is noteworthy since it refutes prior precedent that allowed a contractor to assert that the liquidated damages should not be assessed since the public entity delayed the project during a period of concurrent delay.
