4. Automatic control modes
a. Mode of control is selected at the SCADA. The operator will place the Chemical feed pump into Auto and select a desired mode of operation.
5. The chemical feed pump controls modes:
a. On/Off Control – When selected for On/Off control the PLC will start the associated chemical feed pump based on an associated pump running or process flow switch is detected. This mode is generally utilized when a flow pacing signal is not available
13370
(1) SCADA Speed Control – The operator will select SCADA manual control and manually set the speed from the SCADA workstation. (2) In this mode the Pump will Start/Stop automatically from the PLC and utilize the last SCADA speed setpoint value for chemical feed rate.
b. Open Loop Control (Flow pacing) – The PLC will control the chemical pump feed rate based on its associated flow pacing signal. The chemical feed output will be provided with operator adjustable ratio and offset setpoints.
c. Open Loop Control with Trim – The PLC will control the chemical feed rate based on its associated flow pacing signal and a chlorine residual process feedback variable for trimming the output to maintain a desired process parameter such as Chlorine Residual. This mode is often utilized to control chemical waste and maintain residual within a control band.
6. Chemical Feed Pump Control
a. The chemical feed pumps are configured as a duty/standby pump configuration. The duty pump is selected at the SCADA and remaining pump becomes the standby pump.
b. Under normal operation, the duty feed pump is started whenever an effluent pump is started, and the effluent flow is above a minimum setpoint. When these conditions are met the chemical feed rate (dosage) is controlled by PLC based on the existing effluent flow signal. c. The chemical feed pumps will continue to operate until the flow fails below the minimum flow setpoint or the effluent pumps are not running. -END OF SECTION-

Pursuant to the provisions of the Labor Code, eight hours’ labor shall constitute a legal day’s work.

A. In compliance with and pursuant to Government Code Section 4215, AGENCY shall assume the responsibility, as between the parties to this AGREEMENT, for the timely removal, relocation, or protection of existing main- or trunk-line utility facilities located on the site of any construction project that is a subject of this AGREEMENT, if such utilities are not identified by AGENCY in the plans and specifications made a part of the invitation for bids. The Contract Documents shall include provisions to compensate CONTRACTOR for the costs of locating, repairing damage not due to the failure of CONTRACTOR to exercise reasonable care, and removing or relocating such utility facilities not indicated in the plans and specifications with reasonable accuracy, and for equipment on the project necessarily idled during such work. CONTRACTOR shall not be assessed liquidated damages for delay in completion of the project, when such delay was caused by the failure of AGENCY or the owner of a utility to provide for removal or relocation of such utility facilities.
B. To the extent that the work requires trenches in excess of five feet (5’) and is estimated to cost more than $25,000, prior to any excavation, CONTRACTOR must provide the AGENCY, or a registered civil or structural engineer employed by the AGENCY to whom authority has been delegated to accept such plans, a detailed plan showing the design of shoring, bracing, sloping, or other provisions to be made for worker protection from the hazard of caving ground during the excavation of such trench or trenches. If such plan varies from the shoring system standards, the plan shall be prepared by a registered civil or structural engineer. Nothing in this section shall be deemed to allow the use of a shoring, sloping, or protective system less effective than that required by the Construction Safety Orders.
C. This AGREEMENT is further subject to Public Contract Code Section 7104 with regard to any trenches deeper than four feet (4’) involved in the proposed work as follows:
CONTRACTOR shall promptly, and before the following conditions are disturbed, notify AGENCY, in writing, of any:
(1) Material that CONTRACTOR believes may be hazardous waste, as defined in Section 25117 of the Health and Safety Code, which is required to be removed to a Class I, Class II, or Class III disposal site in accordance with existing law.
(2) Subsurface or latent physical conditions at the site differing from those indicated by all available information provided prior to the deadline for submission of bids. (3) Unknown physical conditions at the site of any unusual nature, different materially from those ordinarily encountered and generally recognized as inherent in work of the character provided for in the contract.
AGENCY shall promptly investigate the conditions, and if it finds that the conditions do materially so differ, or involve hazardous waste, and cause a decrease or increase in CONTRACTOR’s cost of, or the time required for, performance of any part of the work, AGENCY shall issue a change order under the procedures described in this AGREEMENT.
In the event that a dispute arises between AGENCY and CONTRACTOR whether the conditions materially differ, or involve hazardous waste, or cause a decrease or increase in CONTRACTOR’s cost of, or time required for, performance of any part of the work, CONTRACTOR shall not be excused from any scheduled completion date provided in the AGREEMENT, but shall proceed with all work to be performed under the AGREEMENT. CONTRACTOR shall retain any and all rights provided either by contract or by law which pertain to the resolution of disputes and protests between the contracting parties.

CONTRACTOR shall take out and maintain, during the life of this contract, Worker’s Compensation Insurance for all of CONTRACTOR’s employees employed at the site of improvement; and, if any work is sublet, CONTRACTOR shall require the subcontractor similarly to provide Worker’s Compensation Insurance for all of the latter’s employees, unless such employees are covered by the protection afforded by CONTRACTOR. CONTRACTOR and any of CONTRACTOR’s subcontractors shall be required to provide AGENCY with a written statement acknowledging its obligation to secure payment of Worker’s Compensation Insurance as required by Labor Code § 1861; to wit: ‘I am aware of the provisions of Section 3700 of the Labor Code which require every employer to be insured against liability for workers’ compensation or to undertake self-insurance in accordance with the provisions of that code, and I will comply with such provisions before commencing the performance of the work of this contract.’ If any class of employees engaged in work under this AGREEMENT at the site of the Project is not protected under any Worker’s Compensation law, CONTRACTOR shall provide and shall cause each subcontractor to provide adequate insurance for the protection of employees not otherwise protected. CONTRACTOR shall indemnify and hold harmless AGENCY for any damage resulting from failure of either CONTRACTOR or any subcontractor to take out or maintain such insurance.
ARTICLE VII: Indemnification
To the fullest extent permitted by law, CONTRACTOR shall, at its sole cost and expense, fully defend, indemnify and hold harmless AGENCY, its authorized representatives and their respective subsidiaries, affiliates, members, directors, officers, employees and agents (collectively, the “Indemnitees”) from and against any and all claims, actions, demands, costs, judgments, liens, penalties, liabilities, damages, losses, and expenses, including but not limited to any fees of accountants, attorneys or other professionals (collectively “Liabilities”), arising out of, in connection with, resulting from or related to, any alleged act, omission, fault or negligence of CONTRACTOR, CONTRACTOR’s Representative, or any of its officers, agents, employees, Subcontractors or Suppliers, or any person or organization directly or indirectly employed by any of them (Collectively, the “Indemnitors”), in connection with or relating to or claimed to be in connection with or relating to the work performed under this AGREEMENT.
CONTRACTOR shall not be entitled to any refund of attorneys’ fees, defense costs and expenses in the event that it is adjudicated to have been non-negligent.

If CONTRACTOR is a joint venture or partnership, each venturer or partner shall be jointly and severally liable for any and all of the duties and obligations of CONTRACTOR that are assumed under or arise out of this AGREEMENT. Each of such venturers or partners waives notice of the breach or non-performance of any undertaking or obligation of CONTRACTOR contained in, resulting from or assumed under this AGREEMENT, and the failure to give any such notice shall not affect or impair such venturer’s or partner’s joint and several liability hereunder.
ARTICLE VIII: Binding Effect
