Sources and Authority
• Unreasonable Delay. Public Contract Code section 7102.
• “Delay damages are a common element recoverable by a party aggrieved by the
breach of a construction contract.” (JMR Construction Corp. v. Environmental
Assessment & Remediation Management, Inc. (2015) 243 Cal.App.4th 571, 585
[198 Cal.Rptr.3d 47].)
• “A subcontractor who is responsible for delaying the progress of a construction
project may be held liable for delay damages incurred by the general contractor
or by another subcontractor.” (JMR Construction Corp,supra, 243 Cal.App.4th
at p. 586.)
• “ ‘A building contractor whose performance is delayed by the owner may have
increased overhead and fixed costs resulting from a delay and may suffer labor
and material cost increases or loss of labor productivity due to delays for all of
which he or she would be entitled to damages.’ Extended home office overhead
is one type of delay damages for which a contractor may seek recovery.” (JMR
1319

Construction Corp,supra, 243 Cal.App.4th at p. 586, internal citation omitted.)
• “Overhead expense allocable to the period of delay is allowed to the extent the
evidence shows an increase in overhead because of the breach; or where other
jobs, but for the delay, would have been obtained to absorb such overhead.” (A.
A. Baxter Corp. v. Colt Industries, Inc. (1970) 10 Cal.App.3d 144, 158 [88
Cal.Rptr. 842], internal citations omitted.)
• “We conclude the trial court did not err in applying the Eichleay formula as a
legally permissible method of determining JMR’s home office overhead
damages. We base this conclusion upon the expert evidence presented at trial,
the general recoverability of extended home office overhead as an element of
delay damages, and the federal courts’ general acceptance of the Eichleay
formula.” (JMR Construction Corp,supra, 243 Cal.App.4th at p. 587.)
• “The federal courts have identified three Eichleay requirements. ‘[T]he contractor
[must] establish: (1) a government-caused delay; (2) that [the contractor] was on
“standby”; and (3) that [the contractor] was unable to take on other work.
[Citation.]’ ” (JMR Construction Corp,supra, 243 Cal.App.4th at p. 588.)
• “[A] contractor cannot recover on a claim for unabsorbed office overhead where
it is able to meet the original contract deadline or finish early despite a
government-caused delay. An exception applies where the contractor
demonstrates from the outset an intent to complete the work early, a capacity to
do so, and a likelihood of early completion but for the government’s delay.
Application of the three-prong test requirement . . . , however, is required only
where the contractor finishes the work by the original specified contract
completion date or earlier.” (Howard Contracting, Inc. v. G.A. MacDonald
Construction Co. (1998) 71 Cal.App.4th 38, 54-55, [83 Cal.Rptr.2d 590].)
