CITY OF CAP I EAU, MISSOURI BY: NAME: TITLE: DATE: City of Cape Girardeau Addendum 1 to Amendment No. 1 RJN GROUP, INC. BY: 0 L -IA NAME: Lisa S. Douglas, P.E. TITLE: Principal DATE: May 6, 2011 Page 2 of 2 r 1 n group The Choice for Collection System Solutions Addendum No. 1 to Amendment 1 EXHIBIT B CAPE GIRARDEAU PHASE II SSES SCOPE OF SERVICES A. SCOPE OF SERVICES The Services to be provided under this Proposal shall consist of a Phase II SSES and report to complement the City's capacity, management, operations, and maintenance (CMOM) and new wastewater treatment plant efforts. Phase II will be timed in accordance with the City's needs and be tailored to match the requirements and expectations of the Missouri Department of Natural Resources. Phase II will consist of- a. £ a. Project Goals — The goals for the SSES include: • Evaluate, identify, and quantify sources of I/I for the study areas • Identify, propose, and prioritize recommendations to reduce the amount of I/I entering the collection systems • Develop budgetary cost to repair I/I in the study areas • Complete the above goals by December 1, 2011 b. Work Performed for the Project • Project coordination • Manhole inspections • Smoke testing • Dyed water flooding/dye tracing • Wet -weather inspections • Closed-circuit television (CCTV) • Final report and recommendations www.rjn.com The team includes RJN as the primary firm and sub -contractor ACE Pipe Cleaning, Inc. (Ace Pipe) for CCTV services. r i n group 2 1. Technical Approach to the Project Scope of Work A. Project Coordination Preliminary/Project Kick -Off Meeting — A meeting will be held with the City Public Works staff and RJN staff. This meeting will review the program objectives and time lines and define the roles of each project team member. This meeting will also provide the overall framework, work flow, and standards for the SSES program. Recommended topics include: • I/I field investigation procedures • Codes, standards, naming conventions, numbering systems, and forms • Source data dictionary and flow quantification • Program plan/basin prioritization refinement • Data management/delivery • Work flow/coordination • Rights of access/traffic control Project coordination will also include project mobilization. Work Plan — A work plan will be presented at the onset of the project and will be used as a "living" document to guide project activities. This plan will be a flexible tool and will be modified/updated as needed. The work plan will provide a detailed schedule with dates and milestones. Quality Assurance/Quality Control (QA/QC) Plan — RJN has spent the last 35 years improving processes and controls to provide reliable SSES data to clients. This project will be no different. RJN has several points of project development where QC measures will define reliable conclusions, I/I quantification, and the appropriate approach to recommendations. These procedures will include a certain percentage of repeat field activities to determine if the repeated inspection coordinates with the original one. Our flow balancing techniques, where flow metering information is available, also provides the City with a high degree of confidence that the UI investigation is comprehensive in its approach and major sources of UI are not overlooked. The final QA/QC determination is the proof with the elimination of overflows and basement backups in the areas reportedly where various wet -weather problems exist. Progress Meetings — Regular progress meetings will be conducted with the City. Meeting agendas and technical memorandums will be prepared and distributed prior to the meetings, and meeting minutes/follow-up action lists will be distributed after each meeting. For purposes of this proposal, it is assumed that progress meetings will be once every three weeks. It is anticipated that the first monthly meeting will be one week after Council approval. Project Tracking — RJN routinely uses thematic mapping tools such as ArcView to manage and communicate the project status to team members and City staff. Thematic mapping is also used rr n_r to convey improvement and rehabilitation recommendations. Project tracking against the project schedule developed as part of the work plan will also be conducted. Historical Data Review/Data Collection — RJN will review the existing system maintenance records and any trouble call reports. We will also review historical sanitary sewer overflow reports, former investigation data, and operations data for pump stations in the service area. This data will be used to prioritize study areas, determine investigation methods, and consider alternative inspection methods to overcome any identified challenges. B. Inspections and Testing Manhole/Visual Pipe Inspection — RJN will perform comprehensive full -descent inspections of manholes over 10 feet deep; those under 10 feet deep will be inspected from at grade. All subsurface manhole components from the frame seal, walls, and manhole bench and trough will be inspected. Visual pipe inspection will include invert measurements at each line segment, if possible, in addition to detecting line conditions from the manhole. Photographs of major manhole defects will be taken. Dual -Blower Smoke Testing — This task will specifically identify sections of sewer lines and sources where excessive I/I may be expected to occur during wet -weather periods including locations of storm water transfer into the sanitary sewer system. A dual -blower, intensified smoke technique will be utilized to test sewer lines in the selected study area. This enhanced method uses two smoke blowers for each test segment instead of the conventional technique of one blower. Experience has shown that four to six times as many defects are observed using this method. Smoke testing will be performed only during dry periods to maximize effectiveness of the smoke testing program. Locations and severity of the smoke will be recorded. Locations of all identified inflow defects will be shown on the geographic information system (GIS) maps with all data and photographs of the defects. The linear footage and manhole totals for each metered sub -basin to be inspected are: Metered Areas Manholes Linear Feet 2 360 80,943 10 449 96,401 22 586 141,273 19 & 21 179 69,115 15 58 9,933 7 258 58,891 Totals 1,890 456,556 Dye Tracing — It must be noted that smoke testing does not locate all discrete sources of I/I. Because of that, it is important that another level of field screening be performed to provide the r i n group 4 City with the confidence that they are receiving a comprehensive SSES program. Many of the potentially major sources of UI cannot always be identified from smoke testing (i.e., downspouts, driveway drains, and yard drains). RJN field crews will record "suspect sources" located on private property during smoke testing activities. These suspect sources are sometimes "trapped" and will test positive with dye tracing. Suspect sources will be followed up after smoke testing with dyed water tracing using a non-toxic fluorescent dye, quantified, and inputted into the flow quantification database when found to be connected to the sanitary sewer. Dyed Water Flooding — Identified inflow from directly connected storm sewer facilities has the potential to be a major contributor to extraneous flow during wet -weather events. Because that potential exists and the City needs to understand the magnitude of the inflow to assist with prioritization, inflow sources and quantifications from each source will be identified by means of dyed water flooding of storm sewer sections and suspected overflows, stream sections, ditch sections, and ponding areas that may be contributing to inflow. The dyed water flooding test areas are based on results of the smoke testing program. Positive dye flooding tests are quantified for leakage rate, especially sanitary/storm cross connections. Inflow sources can be pinpointed by surface flooding sewer sections with dyed water to verify storm sewer connections, suspected overflows, streams, ditches, and ponding areas that may contribute to the system inflow. For purposes of this proposal, it is estimated that 32 crew days will be required to complete dye tracing/dye flooding activities. The actual number of days required will be based on the survey findings of smoke testing and will be performed on an as - needed basis. Specific activities will be defined at the end of smoke testing activities. Quantification and discrete cross connection location information will be recorded, along with any attributes required by the City. CCTV will be performed as necessary and simultaneously with dye flooding to better evaluate the source and correction required. Dyed water testing can be effective during TV inspection to witness the source and quantify the magnitude of UI. CCTV Work — CCTV is specifically used to pinpoint system defects, define their magnitude, and determine the most -appropriate method of rehabilitation. RJN's CCTV contractor is Ace Pipe. RJN will be providing field oversight and office -required CCTV review and analysis. RJN will assist Ace Pipe in troubleshooting field activities such as structure location and identification and coordinating map updates for new structures not located on facilities maps. RJN will also be providing office review for all CCTV and performing the QC procedures. RJN has Pipeline - Assessment -and -Certification -Program -certified (PACP-certified) personnel available for review and QC activities. All televised observations will be digitally recorded and provided electronically to the City. Audio commentary will accompany the video inspection. The database will be provided in WINCAN8 software format. Data will be collected and categorized using PACP standards. During the course of field activities, line segments in need of cleaning activities due to excessive debris are often identified. For purposes of this proposal, it is assumed that 10% of the total linear feet will have CCTV and associated light cleaning. Throughout CCTV fieldwork, RJN and Ace Pipe will coordinate any map update requirements. r i n group Wet -Weather Inspections — Certain areas such as tributaries and low-lying areas present opportunities to physically witness the influence of I/1. During wet -weather periods, when smoke testing is the least efficient, crews will perform aboveground reconnaissance. Through wet -weather inspections, crews are able to witness 1/I and observe system anomalies as they occur to better pinpoint and quantify them. For purposes of this proposal, it is assumed that a total of eight wet -weather days will be used for inspection by field crews. Dye test crews will be provided to perform these inspections. C. Data Analysis and Reporting Quantification and Balancing of Inflow Defects — Field survey information including observation of physical conditions and I/I source leakage rates provides the database needed for quantification of individual 1/1 source defect flow rates under design storm conditions. These defect flow rates are based on specific 1/1 source flow rate equations. Balancing of inflow defects is performed on separate sewer system studies where flow monitoring data are available. Flow rates based on actual field observations can also be entered during the data input process. RJN will estimate flows for each defect identified based on the 1 -year, 30 -minute storm event. Rehabilitation methods and costs, along with I/I source flow rates, vary according to the physical characteristics of the individual defects identified and prioritized. Immediate Action Repairs — RJN field technicians are trained to identify critical situations requiring emergency attention. Situations may be identified during fieldwork that pose significant risks to public safety, the environment, or the structural integrity of the collection system. These will be reported to the City immediately to ensure public safety and to protect the environment. Standard protocols for communication and initiation of procedures leading to design and implementation of critical repairs for high-risk situations will be defined during project initiation. Potential types of critical situations include: Manholes without covers in public areas Active dry -weather system overflows Collapsed pipes in streams There will be three processes related to data delivery. 1. One process will be the hand entry of data collected, smoke testing, dyed water flooding, and building inspections. 2. CCTV data will be supplied in a compatible format to that of the City's. 3. Manhole inspection data will be inputted into our CASS database, and the completed database will be submitted to the City. ringroup 6 GIS Data Delivery — In addition, shape files will be developed of defect data for submittal to the City. Selection of Rehabilitation Methods — Once all defects have been located, quantified, and prioritized, decisions can be made on the approximate repair method for each identifiable defect. There are various design and construction techniques that can be implemented as part of the recommendation and design solutions of this project: • Conventional open cut • Trenchless technologies (cured -in-place pipe [CIPP], pipe bursting, pipe reaming, slip lining, etc.) • Private inflow source removal • Private lateral repairs • Manhole rehabilitation/replacement • Point repairs • Pump station upgrades • "Green" low -impact development techniques Each solution developed by RJN will be based on our knowledge and 35 years of experience with UI quantification and collection system performance. D. Final Report and Recommendations — Technical memorandums summarizing specific tasks will be submitted upon completion of fieldwork and data analysis. Quantified total 1/I and removal recommendations will be provided in our standard SSES report format. Defects will be graphically illustrated on a GIS map to show location and severity of defects and included with the report. The draft reports will be submitted to the City and finalized based on one set of comments from the City. Three final report copies with related data and respective DVD appendix will be submitted to the City. Rehabilitation methods that will be evaluated for 1/I removal will include repairs of manholes, sewer mains, interceptors, and laterals. Typical manhole repairs include complete replacement, frame sealing, grade adjustment, manhole wall coating and grouting, pipe seal repair, bench and trough repair, and manhole lining. Mainline and interceptor rehabilitation methods will include point repairs; rerouting, capacity improvements, or replacement; section replacement; and trenchless technology such as slip lining, CIPP, bursting or crushing, or directional drilling. Lateral repairs will include replacement, point repairs with emphasis on lateral -to -main connections, trenchless methods, and cleanout repairs. Current rehabilitation costs will be used and updated as necessary. Recommendations will be graphically represented on a GIS -based map and included as part of the report. The GIS deliverable will provide a spatial comparison between the current GIS layer and the global positioning system (GPS) sewer layer. It is essential to carefully associate GPS -surveyed manholes with the City's GIS to preserve the integrity of the GIS feature identifiers and related attribute data. RJN will deliver a GIS project file and source data for migration into the City's GIS system. Thematic maps representing defects and recommendations will be developed as part of the report. 2.
