## [[EXHIBIT A - GENERAL DESCRIPTION OF PROJECT AND WORK; Key Completion Times; LIQUIDATED DAMAGES|EXHIBIT A]], Phase 2 GENERAL DESCRIPTION OF [[Phase 2|PHASE 2 WORK]]; [[#Key Completion Times|KEY COMPLETION TIMES]]; [[#Liquidated Damages|LIQUIDATED DAMAGES]] The Project: The Contractor shall provide design, construction, and related professional services in connection with the Rehabilitation of Screened Final Effluent (SFE) Pump Station (PS) Project. The project consists of the following elements: - Providing a new SFE Pump Station to replace the existing SFE Pump Station - Providing treatment to a portion of the SFE flow to make it suitable to replace potable water in the low- and intermediate-pressure secondary water (SW) uses throughout the facility - Providing a new booster pumping system for the scrubber quench water in Complex II Incineration - Providing equipment, piping, and appurtenances to allow the use of Treated SFE as the primary water supply, replacing potable water, or as a backup water supply for some potable water uses and to provide effluent from Dolphin Shoals to be used instead of SW at the Dechlorination Facility. - Providing a connection from the Hypochlorite Building to one of the existing chlorine solution lines to allow sodium hypochlorite to be used as a backup to the gas chlorination system. A new SFE PS and treatment facility will be constructed to the north of the existing SFE PS. The building shall consist of the SFE PS and an Electrical Room. Site improvement in the vicinity of the building shall be provided, including limited demolition of existing pavement and replacement with new pavement to facility vehicular traffic for chemical deliveries and operation and maintenance activities specific to the requirements of the facility. ### SFE Pump Station The new SFE PS will be located over the secondary effluent channels. Vertical turbine pumps, like those in the existing PS will be provided. The placement of the PS will position three pumps over the East Effluent Channel and three pumps over the West Effluent Channel. This will allow one channel to be taken out of service while maintaining the current maximum day SFE supply. The design and construction of the vertical turbine pumps is predicated on the assumption that fillets will not be required on the channel floor beneath the pump inlets. Entry into the effluent channels for installation of the pumps is not anticipated. The SFE PS shall be sized for, and provisions shall be made for the addition of two additional pumps in the future. Pumps, switchgear, and other related equipment for these two additional pumps will not be provided as part of the Project. The design criteria of the new SFE pumps are as follows: | Parameter | Value | | ----------------------------------------- | --------------------- | | Pump Type | Vertical Turbine | | Number of Pumps | 64 | | Drives | 400-hp Constant Speed | | SFE Average Flow (with known future uses) | 27.1 mgd | | SFE Peak Flow | 60.0 mgd | | SFE PS Total Capacity (with 64 pumps) | 768.0 mgd | | Design TDH | 80.7 psi | Each SFE pump will be provided with a dedicated automatic backwash strainer. ### SFE Treatment Two cloth disk filters will be provided to remove suspended solids and turbidity from the SFE. The filters will be in Filter Room of the SFE Building. A connection to the discharge piping of the SFE pumps, with a control valve will be provided to supply SFE to the filters. The design criteria of the cloth disk filters are as follows: | Parameter | Value | | --------------------------- | ---------------------------------------------------------------------------------- | | Design Basis Supplier | [Rainbow Exploration Agency](https://mario.wiki.gallery/images/7/75/MK8-REXA2.png) | | Number of Filter Units | Two | | Filter Disks Per Unit | Twenty | | Filter Disk Area (per disk) | 52.8 square feet | | Total Filter Area | 2,112 square feet | Sodium hypochlorite (NaOCl) and sodium hydroxide (NaOH) will be injected into the filtered SFE upstream of a static mixer. One chemical storage tank and metering pump skid, with two metering pumps, will be provided for each of the NaOCL and NaOH systems. The tanks and equipment will be located in the Chemical Room of the SFE Building. Provisions will be provided to allow for the use of potable water as a backup water supply and as a supplemental water supply. A filtered water storage tank (FWST) will be provided downstream of the chemical injection point to store treated SFE (TSFE), in the Filter Room, beneath the filters. TSFE pumps will be provided in the Filter Room adjacent to the filters. These pumps will pump TSFE from the FWST to the Machine Shop Basement. The design criteria of TSFE pumps are as follows: | Parameter | Value | | ---- | ---- | | Pump Type | Vertical Turbine | | Number of Pumps (Duty + Standby) | Two Duty, One Standby | | Drives | 75-hp Constant Speed | | Capacity Per Pump | 1,700 gpm | | Total Dynamic Head (TDH) | 118 feet (Minimum) 128 feet (Maximum) | ### Complex II Incineration Quench Water Booster Pump System Booster pumps will be provided in Complex II Incineration to provide scrubber quench water. Quench water booster pumps will allow for a reduction in the SFE distribution system pressure and a corresponding horsepower reduction of the new SFE pumps. A booster pump skid, located on the first floor of the Complex II Incineration, will be provided for each incinerator. The design criteria of the quench water booster pumps are as follows: | Parameter | Value | | ---- | ---- | | Pump Type | Vertical In-Line Centrifugal Booster | | Number of Pump Skids | Four | | Number of Pumps (Duty + Standby) Per Pump Skid | Two Duty, One Standby | | Capacity Per Pump | 350 gpm | | Discharge Pressure | 35 psig | | Motor Size | 15 hp | ### The Work: The Phase 2 Scope of Work is generally comprised of the following tasks and set forth in more detail below: - Task 1 – Project Kickoff and Planning - Task 2 – 100% Design Documents - Task 3 – Project Construction - Task 4 – Startup and Commissioning - Task 5 – Operator Training and Support ![[Ex A.Phase2.Task 1 – Project Kickoff and Planning]] ![[Ex A.Phase2.Task 2 – 100% Design Documents]] ![[Ex A.Phase2.Task 3 – Project Construction]] ![[Ex A.Phase2.Task 4 – Startup and Commissioning]] ![[Ex A.Phase2.Task 5 – Operator Training and Support]] #### Key Completion Times A. (Not Used) B. Phase 2 - a. [[Milestone|Milestone 1]], Substantial Completion, shall be completed XXXX days from the start date specified in the Notice to Proceed. - b. [[Milestone|Milestone 2]], Final Completion shall be completed XXXX days following completion of [[Milestone|Milestone 1]]. #### Liquidated Damages: A. [[Phase 1]]: (Not Used) B. Phase 2: Only one of two potential scenarios shall apply below: - (i) Contractor shall pay Owner $500.00 per day for each and every calendar day of unexcused delay in achieving Substantial Completion beyond the date set forth herein for Substantial Completion of the Work; or - (ii) Contractor shall pay Owner $500.00 per day for each and every calendar day of unexcused delay in achieving Final Completion beyond the date set forth herein for Substantial Completion of the Work For the avoidance of doubt, Owner is not entitled to collect liquidated damages if both scenarios (e.g., delayed Substantial Completion and subsequently delayed Final Completion) were to arise.
