Cal. PCC § 20894

If the contractor abandons the work, or fails to proceed with it as rapidly as required by the contract, the city forester may relet the work in the same manner as in the first letting, or complete or cause it to be completed in any other manner he or she deems advisable. The city forester may retain the amount of any expense incidental to the reletting, out of any funds due or to become due to the contractor, and may also hold the contractor and the sureties upon the contractor’s bond responsible for any additional expenses and for any damages resulting from the abandonment or failure to complete the contract.
