Consultant will Provide Services. The primary treatment process at the RWF consists of two (2) sets of primary clarifiers, namely the east and west primary clarifiers (“Primary Clarifiers”). The east primary clarifiers, built in the 1960s and 1970s, consist of two hydraulically similar batteries of nine primary tanks operating in parallel with a combined capacity of 330 million gallons per day. The west primary clarifiers, built in the mid-1950s, consist of eight tanks, of which two tanks are used for treating filter backwash water. These tanks have a combined capacity of 60-90 million gallons per day The primary sludge from both clarifiers is removed using progressive cavity pumps. The Primary Effluent Pump Station (“PEPS”) built in the mid-1980s, consists of four (4) vertical turbine variable speed pumps, each with a design capacity of 45 million gallons per day. The PEPS receives effluent from the Primary Clarifiers by gravity and pumps the wastewater to the Biological Nutrient Removal No. 2 treatment system. The PEPS also directs flow to the primary effluent equalization basin located across Zanker Road. The purpose of this Service Order No. 7 (“SO”) is for the Consultant to evaluate the process, structural, mechanical, electrical, and instrumentation/controls components of the Primary Clarifiers and PEPS facilities. The condition assessment will be used to predict the remaining useful life of critical components in these facilities and identify capital assets in need of rehabilitation or replacement. The Consultant will develop a timeline of recommended repairs and/or replacements required to keep the Primary Clarifiers in operation up to the year 2051 and will prepare an opinion of probable construction cost (“OPCC”) and related operation and maintenance (“O&M”) costs for such work. The First Amendment reallocated compensation among tasks and extended the duration. This Second Amendment extends the duration and adds scope for the Consultant to assess the hydraulic capacity of the East Primary Clarifiers, prepare a conceptual construction sequencing plan for the Primary Clarifiers and the PEPS, and update related OPCCs. The conceptual construction sequencing plan and the OPCCs will be reviewed and amended if needed by the design engineer in a subsequent rehabilitation project. This SO consists of the following tasks:

The primary treatment process at RWF has sixteen (16) nitrification clarifiers that were constructed during the RWF 1970s and 1980s to support the Biological Nutrient Removal 2 (“BNR2”) process, which consists of two separate treatment trains identified as Battery A and Battery B. Each train consists of eight (8) aeration basins, one (1) mixed liquor open channel, eight (8) clarifier influent valve boxes, eight (8) clarifiers, and eight (8) return activated sludge (“RAS”) pipelines routed from the clarifiers to the Tertiary Blower Building RAS galley. Single 42- inch pipelines serving each clarifier connect the inlet mixed liquor open channel to the clarifier inlet flow split boxes. There is a connecting channel between the two (2) sets of primary mixed liquor channels (each serving eight clarifiers, namely the east and west primary clarifiers (“Primary Clarifiers”)) with isolating wood sluice gates. The east primary clarifiers, built BNR2 process initially worked in the 1960s and 1970s, consist of two hydraulically similar batteries of nine primary tanks operating in parallel series with a combined capacity of 330 million gallons per day. The west primary clarifiers, built in the mid-1950s, consist of eight tanks, of which two tanks are used for treating filter backwash water. These tanks have a combined capacity of 60-90 million gallons per day The primary sludge from both clarifiers is removed using progressive cavity pumps. The Primary Effluent Pump Station (“PEPS”) built in the mid-1980s, consists of four (4) vertical turbine variable speed pumps, each with a design capacity of 45 million gallons per day. The PEPS receives effluent from the Primary Clarifiers by gravity and pumps the wastewater to the Biological Nutrient Removal No. 2 treatment system1 (“BNR1”) process, but was modified in 1991 to operate in parallel with BNR1. The PEPS also directs flow to clarifiers have been in operation for more than 30 years and many components are nearing the primary effluent equalization basin located across Zanker Roadend of their useful life. The purpose Project replaces clarifier mechanisms and appurtenances (including access bridge, walkway, inlet baffles, xxxx plates, xxxx cleaning system, scum baffles, and scum collection system) for eight (8) clarifiers, modify service water system and add wash water piping and hose bibs, repair concrete clarifier walls and slabs, replace drain valves and RAS valves serving A-side and B-side clarifiers, rehabilitate clarifier basin groundwater pressure relief valves for the sixteen (16) clarifiers, rehabilitate up to eight (8) RAS pipelines, install six (6) groundwater monitoring xxxxx, replace two (2) mixed liquor channel sluice gates, and replace electrical and instrumentation and control equipment for all sixteen (16) clarifiers. The construction started in November 2019 with anticipated substantial completion by December 2023. The objective of this the Service Order No. 7 5 (“SO”) is for the Consultant to evaluate the process, structural, mechanical, electrical, provide professional construction management and instrumentation/controls components of the Primary Clarifiers and PEPS facilities. The condition assessment will be used to predict the remaining useful life of critical components in these facilities and identify capital assets in need of rehabilitation or replacement. The Consultant will develop a timeline of recommended repairs and/or replacements required to keep the Primary Clarifiers in operation up to the year 2051 and will prepare an opinion of probable construction cost (“OPCC”) and related operation and maintenance (“O&M”) costs for such work. The First Amendment reallocated compensation among tasks and extended the duration. This Second Amendment extends the duration and adds scope electrical inspection services for the Consultant to assess the hydraulic capacity of the East Primary Clarifiers, prepare a conceptual construction sequencing plan for the Primary Clarifiers and the PEPS, and update related OPCCs. The conceptual construction sequencing plan and the OPCCs will be reviewed and amended if needed by the design engineer in a subsequent rehabilitation projectProject.
