4.0 SCOPE OF WORK
4.1 D
escription of Work and Schedule
The splash pad is automated and uses an Ultraviolet Filter, sensors, and probes to maintain healthy sanitation levels and keep the splash pad compliant with San Joaquin County Health Code requirements. There is a chlorine feeder and 3 sand tanks needing daily checks when the system is operational. The system requires the use of Chlorine tablets in the automatic feeder. Bromine is not allowed to be used with this system; furthermore, no chemicals will be allowed to be stored in the pump/filtration building (utility building). The sand tanks need backwashing after a rise of 8 pounds per square inch. Currently, the clean system runs with a pressure of 12 pounds per square inch.
The contractor shall maintain all records and logs required by these Special Provisions, the Regulations, and the Public Pool Standards. All updated logs shall be provided to the Contract Administrator with each pay application request.
The contractor shall provide all labor, materials, chemicals, tools, supplies, including all chemicals and testing materials, equipment, and transportation necessary to provide services described in these special provisions.
4.2.1 Hours and Days of Work
Contractor will provide a schedule of days and times that maintenance services will be performed at the splash pad. Contractor shall provide said schedule within fifteen (15) calendar days of contract award.
Contractor must have the splash pad ready a minimum of one (1) hour prior to that day’s scheduled opening. The City reserves the authority to direct the Contractor to amend the working hour schedule if conflicts are apparent. If scheduling problems develop, the City and Contractor will review and change the schedule as necessary.
4.2.2 Splash Pad Maintenance/Water Quality Services For the following services, the contractor shall keep logs of all maintenance operations and chemical usage in accordance with the applicable regulations.
Such records shall be subject to approval by the Contractor Administrator or representative. Hardcopy logs and maintenance records shall be kept in the splash pad utility building for City inspection. A copy (PDF document) of these logs will be sent to the Contract Administrator with each month’s invoice for services.
A. Water Quality
Contractor should maintain water quality and chemistry in accordance with the most current versions of the Regulations and the Public Pool Standards. At no
ATTACHMENT A
time shall the water quality/chemistry cause a failure of permission to operate the fountain as granted by the regulatory agency.
The fountain is automated and could shut down if sanitation levels are outside normal ranges. Any reading outside the normal range, is unacceptable and will constitute an Emergency Call-Out response by the contractor at no charge to the City. The acceptable range of pH (potential of hydrogen) is 7.2 to 7.8 (the City’s desired level is 7.5) and the FC (or free chlorine) count shall be maintained between 3.0 and 10.0 (the City’s desired level is 5.0).
The Contractor shall not change any of the valve positions or change out any equipment without prior direction from the Contract Administrator.
In the event permission to operate is revoked due to poor water quality/chemistry caused by Contractor's actions (or lack of proper maintenance), the Contractor's invoice for the month will be reduced by 1/30 of the Monthly Maintenance Service cost for each day the fountain cannot be opened/operated during that service month. There will be no credit for subsequent partial days of operation following a City or County required fountain closure related to lack of proper maintenance or action by the Contractor.
B. Start Up Service
Contractor shall have the start-up service complete and have the splash pad ready for full operation by May 20th each year of the contract. Start-up service shall consist of the following tasks:
