Guarantees. CONTRACTOR shall, and hereby does, guarantee all work for a period of one (1) year after the date of acceptance of the work by the DISTRICT and shall repair and replace any and all such work, together with any other work which may be displaced in so doing, that may prove defective in workmanship and/or materials within the one (1) year period from date of acceptance, without expense whatsoever to the DISTRICT, ordinary wear and tear and usual abuse or neglect excepted. In the event of failure to comply with the aforementioned conditions within five (5) days after being notified in writing, the DISTRICT is hereby authorized to proceed to have the defects repaired and made good at the expense of the CONTRACTOR, who shall pay the cost and charges therefor immediately on demand. This guarantee shall be in addition to any manufacturer or specific guarantees that may be required. CONTRACTOR shall provide those manufacturer and specific guarantees before CONTRACTOR may claim entitlement to final payment. INDEMNIFICATION 27. Indemnity. CONTRACTOR shall indemnify, defend with legal counsel approved by DISTRICT, and hold harmless DISTRICT, and its officers, officials, employees, and volunteers, from and against all liability, loss, damage, expense, and cost (including without limitation reasonable legal counsel fees, expert fees, and all other costs and fees of litigation) of every nature arising out of or in connection with CONTRACTOR’s negligence, recklessness or willful misconduct in the performance of work hereunder, or its failure to comply with any of its obligations contained in this AGREEMENT, except such loss or damage which is caused by the sole or active negligence or willful misconduct of the DISTRICT. Should conflict of interest principles preclude a single legal counsel from representing both DISTRICT and CONTRACTOR, or should DISTRICT otherwise find CONTRACTOR’s legal counsel unacceptable, then CONTRACTOR shall reimburse the DISTRICT its costs of defense, including without limitation reasonable legal counsel fees, expert fees, and all other costs and fees of litigation. The CONTRACTOR shall promptly pay any final judgment rendered against the DISTRICT and its officers, officials, employees, and volunteers with respect to claims determined by a trier of fact to have been the result of the CONTRACTOR’s negligent, reckless or wrongful performance. It is expressly understood and agreed that the foregoing provisions are intended to be as broad and inclusive as is permitted by the law of the State of California and will survive termination of this ATTACHMENT B MENDOZA PUMP STATION FORCE MAIN REHAB & IMPROVEMENTS CMSD # 349 CMSD A-9 Agreement 2024 AGREEMENT. CONTRACTOR’s obligations under this Section apply regardless of whether or not such claim, charge, damage, demand, action, proceeding, loss, stop notice, cost, expense, judgment, civil fine or penalty, or liability was caused in part or contributed to by an Indemnitee. However, without affecting the rights of DISTRICT under any provision of this AGREEMENT, CONTRACTOR shall not be required to indemnify and hold harmless DISTRICT for liability attributable to the active negligence of DISTRICT, provided such active negligence is determined by agreement between the parties or by the findings of a court of competent jurisdiction. In instances where DISTRICT is shown to have been actively negligent and where DISTRICT’s active negligence accounts for only a percentage of the liability involved, the obligation of CONTRACTOR will be for that entire portion or percentage of liability not attributable to the active negligence of DISTRICT. Notwithstanding any limits provided for indemnification, CONTRACTOR’s duty to defend is broader. CONTRACTOR agrees to provide DISTRICT with a defense, with counsel reasonably acceptable to DISTRICT, or pay DISTRICT’s costs of defense upon service of any complaint, petition or other pleading that requires DISTRICT to defend itself in any proceeding arising out of the work described in this AGREEMENT. Said obligation shall not extend to disputes between CONTRACTOR and DISTRICT. INSURANCE 28. Insurance. Without limiting CONTRACTOR’s indemnification of DISTRICT, and prior to commencement of work, CONTRACTOR shall obtain, provide, and maintain at its own expense during the term of this AGREEMENT policies of insurance of the types and amounts described below and in a form satisfactory to DISTRICT.

The policy limit shall be no less than $1,000,000.00 per claim and in the aggregate. All activities contemplated in this AGREEMENT shall be specifically scheduled on the policy as “covered operations.” The policy shall provide coverage for the hauling of waste from the PROJECT site to the final disposal location, including non-owned disposal sites. Products/completed operations coverage shall extend a minimum of three years after PROJECT completion. Coverage shall be included on behalf of the insured for covered claims arising out of the actions of independent contractors. If the insured is using subcontractors, the policy must include work performed “by or on behalf” of the insured. Policy shall contain no language that would invalidate or remove the insurer’s duty to defend or indemnify for claims or suits expressly excluded from coverage.

Changes, Change Orders, Unilateral Change Orders, Field Orders, modifications, and adjustments to the Contract Sum or completion date shall in no way release or exonerate the CONTRACTOR or its Surety from their obligations, and notice thereof shall be waived by the Surety. The foregoing provision shall be included in the terms of the Payment Bond, Performance Bond, and any bonds obtained by the subcontractors. Communications.

B. Should CONTRACTOR, at any time during the progress of the work, refuse or neglect to supply sufficient material or labor, or fail in compliance with any provision of this AGREEMENT, DISTRICT shall have the right, without prejudice to any other right or remedy it may have, to provide such materials and labor, or make good such deficiencies as DISTRICT may deem expedient after three (3) day notice in writing, delivered or mailed to CONTRACTOR at his last address on file with DISTRICT, and CONTRACTOR shall be liable for the cost and expense thereof which may be deducted by DISTRICT from any money due or that may become due CONTRACTOR.
