Smith, Clerk of Court and Comptroller By: Approved: Deputy Clerk Baird, County Administrator Approved as to form and legal sufficiency: an T. Reingold, County Attorney EXHIBIT #1 Work Order Number Water Distribution System Modeling Support PROJECT UNDERSTANDING Indian River County Utilities (IRCU) desires to update their water system hydraulic model to reflect current GIS (Geographical Information System) data and better represent their current water distribution system configuration. The existing water system model is in an older version of WaterCAD format, but is outdated and does not reflect current system configuration. In order to integrate the GIS data into a water system hydraulic model, GIS shapefiles will need to be imported into WaterGEMS in order to provide a basis for water system hydraulic modeling and planning. Consultant will prepare a working water system model in WaterGEMS due to its more robust capabilities in developing new models, but will provide a duplicate running model that is compatible with WaterCAD v8. The scope of services detailed below will consist of using WaterGEMS Version V8i (64-bit version), developing a working water distribution model with limited demand data and major nodes and pipe system. The scope will also consist of defining system demands based on monthly operating reports (MOR's), pump station flows and capacities, fire flow requirements, and system design criteria. SCOPE OF SERVICES Task 1 Collect Information and Import GIS Shapefiles into WaterGEMS • Consultant will attend up to three (3) coordination meetings with IRCU staff to discuss the information related to shape files, and information relevant to the development of the new hydraulic model. • Consultant will identify the service area to be studied and prepare a map with its boundaries based on information and discussions with IRCU staff. • Using the ModelBuilder feature of WaterGEMS, Consultant will create a hydraulic model network of the existing water distribution system from the latest GIS shape file provided by IRCU. The new physical alternative of the hydraulic model will consist of o Existing pipes that are 6 -inch in diameter and larger. o Junctions associated with pipes and GIS shapefiles o Tanks (WTP and remote elevated reservoirs — Roseland, Oslo, 58th Ave) o Valves and hydrants • Consultant will use ModelBuilder to provide connectivity of pipe system and nodes. Consultant will work with IRCU staff (IRCU staff to update GIS files if necessary) should pipe connectivity not be possible based on the assumption pipe ends (nodes) to be within 0.1 ft. Up to 20 hours of effort is designated for this task, assuming that the pipes ends are within 0.1 ft and significant effort beyond this amount should be considered additional services KXWPB CiviaC3eneral\Milier\indian River CountyVVRCU Water System Modeling Preparation KHA Scope rev3.doc PAGE - 1 - • Consultant will collect information on the existing water system, including areas of known low system pressures, and discuss approach to developing the water system model with IRCU staff. • Consultant will run Skelebrator to minimize model size, consisting of merging of pipes in series, merge pipes at isolation valves and hydrants, maintaining knowledge of valves and hydrants, etc. Task 2 - Develop New Water System Hydraulic Model • Consultant will review MORs and water meter data to develop unit flow rates for the system. Consultant will review elevated storage and repump operations and update model to include these operations • Consultant will update and develop water system design and operating criteria, consisting of fire flows, peak factors, system pressures, and water demand allocations. Peak factors will be defined based on MOR's and distribution flow meter data. Fire flows will be defined based on ISO and Fire Marshall requirements and IRCU input. • Using the LoadBuilder feature of WaterGEMS, preliminary system demands for TODAY conditions will be developed for up to ten (10) areas for various types of land uses currently identified. These land use types include single family, multifamily, industrial and commercial. Meter reading sets will be evaluated and compared with the demand data to develop these demands. It is assumed that customer meter data is not geocoded and will need to be developed as an additional or future task. It is assumed that an existing spatial relationship between the customer billing database and the base parcel locations data will be manipulated to complete this task and that up to 30 hours of effort is designated for this task. Significant effort beyond this amount should be considered additional services. • Incorporate the specific physical hydraulic features into the model. The physical attributes of the existing system will be imported into the new hydraulic model. Examples of these features include tank sizes, control valve settings, pump curves, and several node elevations where necessary. • Consultant will update elevation data provided by IRCU staff of each node throughout the system that is significant. • It is assumed that nominal pipe diameter will be used for modeling and be based on GIS input pipe diameters database. • Deliverable: A basic hydraulic model network of the water system in WaterCAD v8 format with one (1) topology configuration being TODAY conditions assuming maximum daily flows (MDF) and average daily flow (ADF). Output files of system pressures, flows, and fire hydrant flow test results will be provided. Future Tasks Model results from the scope provided herein will provide initial results of a functioning water system model. It is anticipated that future tasks will include more modeling runs and evaluation including the following: K:\WPB Civil\General\MillerUndian River County\IRCU Water System Modeling Preparation KHA Scope rev3 .doc PAGE - 2 • Better define operation of remote elevated storage tanks and high service pumps • Determine operation of existing high service pumps • Identify weaknesses and low pressure areas in system • Re-establish Stage 2 Testing locations if necessary • Run extended period simulation with elevated tanks • Field calibration of water system model • Develop system scenarios for 5 yr, 10 yr, 20 yr, and buildout conditions SCHEDULE In general, the following schedule is anticipated and consultant will work as expeditiously as possible to meet a mutually agreed upon schedule: Collect Info and Import GIS File 4 — 6 weeks from NTP Develop Model 6 - 10 weeks from NTP FEE SCHEDULE We will provide these services in accordance with our Continuing Services Contract Agreement for Professional Services dated November 15, 2011, with Indian River County. The Consultant will provide professional services for Task 1 through Task 2 on a lump sum fee basis as follows: Task No. Task Task Fee TASK 1 COLLECT INFO & IMPORT GIS FILE $ 9,300 TASK 2 DEVELOP BASE MODEL $ 15,400 TOTAL $ 24,700 ADDITIONAL ITEMS NOT INCLUDED UNDER SCOPE • Improvements outside the primary service area are not included. • Multiple scenarios beyond those listed • Cahbration of model • Geocoding of system wide meter data will need to be developed as an additional service • Updating IRCU's GIS files • Effort to connect the system pipes or develop system demands beyond the hours described in this scope of services • Meetings beyond those fisted herein can be provided as an additional service.
