Our proposal is based on information provided in Exhibit B — Engineering Services provided in an email dated August 7, 2014. 1.2 PROJECT DESCRIPTION The Phase 2 project consists of a permanent raw water intake in a deeper location on Lake Travis to deliver water by gravity to a new high capacity pumping station located adjacent to the City of Cedar Park Water Treatment Plant (WTP). The pumping station will convey water to the Phase 1 raw water pipeline on Trails End Road. Phase 2 includes multiple key elements that will result in the construction of a Deep Water Intake System with an ultimate capacity of 141.7 million gallons per day (MGD). These elements include an intake assembly, maintenance building, gravity flow tunnel, pump station, transmission tunnel, and electrical improvements. The intake capacity is allocated among the owners with BCRUA WTP (105.8 MGD), the City of Cedar Park WTP (23.9 MGD), and the City of Leander WTP (12.0 MGD). BCRUA PHASE 2 DEEP WATER INTAKE Page 1 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal 2.0 SCOPE OF WORK Scope of Work tasks is defined as per Exhibit B — Engineering Services Document, dated August 7, 2014. TASK 1.0 - PROJECT MANAGEMENT, COORDINATION AND MEETINGS Task 1.1 - Project Administration NHC will provide monthly progress reports with an updated schedule with each invoice. TASK 5.0 — INTAKE AND SITE 4 MAINTENANCE FACILITIES Task 5.3.1.3 — Perform CFD Modeling of the Selected Alternative A review of design challenges posed by intakes of WTPs can be found in AWWA and ASCE (1990)1. Depending on the location and orientation, velocity on the screen could be highly non- uniform. Adjacent intakes or screens could interfere and degrade their capacity. Intakes withdrawing water from a lake or a river could affect aquatic organisms such as juvenile fish. If endangered species are present, intakes should include screens to minimize impingement and entrainment. A custom designed screen may need additional considerations, as internal support structures could create eddies and dead -flow zones and increase head losses. Scope of Work Workshop NHC will participate in a one day workshop at HDR's office in Austin to review the selected design, determine data requirements from HDR, identify operating conditions, water levels for the modeling, discuss possible improvements to the design, and review the schedule. Two people from NHC are proposed for the workshop: Tom Demlow, Project Manager, and Liaqat Khan, CFD Modeling Lead. Computational Fluid Dynamics (CFD) Modeling The proposed conceptual raw water intake assembly includes up to four intakes connected to an 84 -inch diameter header, a lake -tap, and a 96 -inch diameter gravity tunnel. The highest and lowest elevations of the intakes are 660 and 565 ft-msl. As currently proposed, four intake levels will be used, and only one of the intakes will be used to withdraw up to 141.7 MGD. NHC proposes the use of STAR -CCM+, a state-of-the-art CFD modeling software package to evaluate the selected Alternative determined in Task 5.3.1.2. The following tasks will be performed for the initial evaluation of the hydraulics of the selected intake layout: 1 AWWA and ASCE (1990). Water Treatment Plant Design. McGraw-Hill, New York, New York. BCRUA PHASE 2 DEEP WATER INTAKE Page 2 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal • Data Collection and Review: The data necessary for the study are bathymetry of the lake, detailed drawings of both preliminary intake structures, and lake water levels corresponding to intake withdrawal rates. This task assumes that all data and information necessary for this study will be provided by HDR. NHC will perform a QA/QC evaluation before using them for the study. • Lake Bathymetric Data Processing: For an accurate prediction of the approach flow, bathymetry of the lake extending sufficiently far from the intake will be necessary. The bathymetric data to be provided by HDR will be analyzed and processed to create a 3-D surface to define the lower boundary of the model domain. If requested, NHC will provide a quote to acquire the necessary bathymetric information. • Geometric Rendering of Model Domain: A 3-D rendering of the selected intake will be created, and will include the intake screens, riser pipe, 84 -inch header pipe, and a segment of the 96 -inch gravity tunnel. This intake will be combined with lake bed to define the model domain. • Computational Mesh Generation: The model domain for the selected intake arrangement will be imported into STAR -CCM+, and a computation mesh will be generated to resolve all the important geometric features. However, note that the screen will be represented by the porous baffle option of STAR-CCM+,without resolving wires creating the porous screen surface. • Baseline Flow Simulation and Analysis: Appropriate boundary conditions will be applied to simulate a steady state for withdrawal of 141.7 MGD through the screens. The model results will be analyzed to visualize the approach flow, velocity distribution on the screens, interaction/interference among the screens, and circulation pattern inside the screen (for internal hydraulics). The following tasks will be performed to optimize the hydraulics of the selected intake layout: Design Modification Modeling: Both the external and internal hydraulics of the selected layout will be reviewed and design modifications will be proposed to improve hydraulic performance of the screens and the intake. For the purpose of cost estimate and schedule, this proposal assumes that three (3) modifications will be sufficient to finalize the design. In addition to updating the model domain geometry, each design modification will require remeshing. This proposal assumes design modifications will be performed for the lowest lake water level at which the intake will be operational. Performance Verification Modeling: This task will verify that optimized design will perform equally well for other lake water levels and water withdrawal rates. For the purpose of cost estimate and schedule, four (4) model runs have been assumed, representing two water levels and two flow rates. This task will require the development of a new computational mesh corresponding to a different water level in the lake. NHC will prepare a report on the model study. The report will describe the technical approach, key assumptions, results of the study, and summary, conclusions, and BCRUA PHASE 2 DEEP WATER INTAKE Page 3 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal f recommendation. Following a quality assurance review, NHC will provide a draft report to HDR. Upon receipt of a consolidated set of comments, NHC will finalize the report and distribute an electronic (PDF) and five (5) printed copies to HDR. Assumptions and Limitations The SOW, cost, and schedule of this proposal are based on the following assumptions: • HDR will provide all data and information for this study, including bathymetry of lake, detailed drawings of the intake structure, and lake water levels, and operating conditions. The SOW does not include task for field data collection. • The proposed system consists of four intakes at different elevations. However, only one intake will be used at a time to withdraw a maximum of 141.7 MGD. In case this assumption is invalid, NHC will request additional work authorization from HDR for the study. • For each operating scenario, the CFD model will simulate steady state flow by applying time independent boundary conditions, and assuming a horizontal water surface throughout the model domain. Further, thermal stratification of the lake, if any, will not be considered in the CFD model. • The design development task will be performed for three (3) design modifications. Further, modeling of four (4) operating scenarios representing different lake water levels and water withdrawal rates will be sufficient for performance verification. If these assumptions become invalid, NHC will request additional work authorization from HDR for completing the study. Task 5.3.4 - Intake Technical Memorandum NHC will prepare a report on the model study. The report will describe the technical approach, key assumptions, results of the study, and summary, conclusions, and recommendations. Following a quality assurance review, NHC will provide a draft report to HDR. Upon receipt of a consolidated set of comments, NHC will finalize the report and distribute an electronic (PDF) and five (5) printed copies to HDR. TASK 7.0 — PUMP STATION Task 7.2 — Preliminary Pump Station Layouts Task 7.2 - Develop Three Concepts Workshop and Desktop Analysis NHC will participate in a one day workshop at HDR's office in Austin to develop the conceptual design alternatives for the pump station. Three preliminary alternatives have been proposed including a single shaft, dual shaft, and individual pump shaft designs. These will be evaluated and enhanced as need be. Two people from NHC are proposed for the workshop: Tom Demlow, Project Manager, and Liaqat Khan, CFD Modeling Lead. BCRUA PHASE 2 DEEP WATER INTAKE Page 4 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal TOM From the Design Criteria Workshop, up to three alternatives will be further developed. The hydraulic evaluation for each concept will be further developed and refined. This will include the potential for high flow pre -swirl, vortex formation, and unbalanced velocities at the pump. This will be based on desktop evaluation along with the CFD results (see Section 7.2.2). Task 7.2.2 — CFD Evaluation of the Three Concepts Operational performance of pumps is strongly influenced by velocity distribution in the approach channel, as determined by the wet well geometry and influent conditions. The HI guidelines for satisfactory hydraulic performance of a pump include an average flow pre -swirl of less than 5°, less than 10 percent deviation of point axial velocity from the mean, and the absence of vortices stronger than Type 1. (Note that these performance criteria are for CFD modeling only, whereas for physical modeling the performance criteria take into account non -steady hydraulics.) For the proposed pump station, a CFD model will be used to evaluate three alternate layouts of the pump station to identify the most promising option that will be further refined using a physical model. Initial Evaluation of the Alternatives The proposed raw water pump station will include a wet well shaft(s) approximately 300 -feet deep, and approximately 10 submersible or vertical turbine pumps. Alternatives being considered include single shaft, dual shaft, and individual shaft designs. Exhibit B suggests evaluation of up to three layouts of the pump station to identify the most promising option for further analysis. NHC will perform the following tasks for each of the alternatives: Data Collection and Review: The data necessary for this study are drawings of the pump station for each alternative, and pump operating conditions. This task assumes that data and information necessary for this study will be provided by HDR. NHC will review the data and perform a QA/QC before using them for developing the model. In addition, considering low, normal, and high flows, the review will also identify up to four (4) critical scenarios for performance evaluation for each alternative (three flow rates at one water level and one test at a different water level). Geometric Renderings of Model Domain: The first step after collecting project related data and information is generating a 3-D CAD rendering of each model domain. Each model domain will encompass the wet well, the pumps, and a sufficiently long segment of the 96 -inch diameter inlet tunnel. Depending on the water level in the lake, several model domains may be necessary. The SOW assumes three model domains corresponding to low, normal, and high flows will be sufficient for the analysis. Computational Mesh Generation: The model domains will be imported into STAR -CCM+, and computation meshes will be generated to accurately resolve BCRUA PHASE 2 DEEP WATER INTAKE Page 5 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal the important geometric features of the model domain. Because of possible changes in water level, up to three (3) computational meshes will be developed for this task for each alternative. Baseline Flow Simulation and Analyses: For each of the computational meshes, appropriate boundary conditions will be applied, and the model will be run to obtain a steady state solution. The results will be analyzed to visualize the approach flow, determine pre -swirl and deviation of the velocity at the pump bell throat, and identify surface and subsurface vortices. Up to four (4) model runs for each alternative will be made and analyzed in this task. Selection of an Pump Intake Layout: The hydraulic characteristics will be compared to determine a preferred pump station layout. This analysis will not take into account any fatal flaws in terms of constructability or maintenance and operating costs. Completion of these tasks will result in nine computational meshes and 12 model runs. Advance Selected Design using CFD (Preliminary 30% Design) Design modifications will be made to improve the approach flow, and reduce pre -swirl and non-uniform velocity at the pump bell throat for each alternative. For the purpose of cost estimate and schedule, this proposal assumes that three (3) design modifications for the selected alternative will be sufficient to achieve an acceptable hydraulic performance. This will result in three model runs at the worst operating condition identified in the initial evaluation. Assumptions and Limitations The SOW, cost, and schedule of this proposal are based on the following assumptions: HDR will provide all data and information necessary for this study, including conceptual -level drawings of the three layouts of the pump station. The CFD modeling approach described in this proposal will simulate steady state flow field in the model domain for each modeling scenario. This modeling approach will not capture temporal variability of the vortices; however, most reported CFD model studies have successfully used this approach for optimizing pump sump hydraulics. Task 7.2.4 — Pump Station Alternatives TM The hydraulic portion of the Pump Station Alternatives Technical Memorandum will be prepared and submitted to HDR. This will include pertinent plots from the CFD analysis for each alternative and other graphics as need be. Recommendations for one of the alternatives will be included with justification. The results from design development of the selected design will be included in the technical memorandum. NHC will provide a draft report in electronic format (PDF) to HDR. Upon receipt of a consolidated set of BCRUA PHASE 2 DEEP WATER INTAKE Page 6 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal comments, NHC will finalize the report and distribute an electronic (PDF) and five (5) printed copies to HDR. Task 7.3 — Hydraulic Analysis Task 7.3.4 — System Pressure Surge Analysis Project Understanding for Pressure Surge Analysis NHC will perform pressure surge analyses for the pump station, gravity flow tunnel (i.e., deep water intake to the wet well at pump station), proposed pressure main/tunnel (i.e., pump station discharge to connection with Phase 1 raw water transmission main), and the existing Phase 1 raw water transmission main. The deep water intake capacity will be allocated to the City of Cedar Park WTP (23.9 MGD), the City of Leander's Sandy Creek WTP (12 MGD), and the Brushy Creek Regional Utility Authority WTP (105.8 MGD). The ultimate capacity is 141.7 MGD. The Cedar Park WTP is adjacent to the pump station site, whereas the Sandy Creek WTP is located approximately one mile downstream of the pump station and the Regional WTP is at the terminus of the Phase 1 raw water transmission main. The deep water intake will have the capability of removing water from Lake Travis at various elevations between EI. 565 ft and EI. 660 ft. The 96 -inch diameter gravity flow tunnel between the deep water intake and the pump station (EI. 500 ft) will be approximately 1.7 miles in length. The pump station wetwell configuration will be developed in Task 7.2. Ten (10) submersible or vertical turbine raw water pumps will be installed in the wet well. Vertical pipes will be installed in the wet well between the discharge of each pump and the 84 -inch diameter pressure main/tunnel (El. 780 ft). The concept level drawings show that surge relief valves are being planned for installation at the pump station. The pressure main/tunnel will be approximately 0.5 miles in length and will connect to the existing 78 -inch diameter Phase 1 raw water transmission main. The Phase 1 raw water transmission main is approximately 4.6 miles in length and terminates at the storage tanks located at the Regional WTP. There are several combination air and vacuum valves installed on the existing Phase 1 raw water transmission main. An analysis of the operation of the interim floating barge pump station near the Cedar Park WTP and the open/close operation of the existing pressure reducing valves at the turnouts to the Cedar Park WTP and Sandy Creek WTP are beyond the scope of NHC's analyses. For this analysis, the take offs to the Cedar Park WTP and Sandy Creek WTP will be treated as constant demands when they are open and zero demand when they are closed. Of primary interest for this project are the pressure transients created by the loss of power to and start-up of the pumps at the pump station. BCRUA PHASE 2 DEEP WATER INTAKE Page 7 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal • A power failure at the pump station is likely to cause the worst-case pressure transients in the system. For example, a loss of power to the pump station will create a pressure drop wave that will propagate out from the discharge side of the pump station and into the pressure main/tunnel and existing Phase 1 raw water transmission main toward the Regional WTP. If the pressure drops sufficiently low in the pipelines to create vapor pressure, vapor cavities will form, and fluid column separation will occur. Upon re -pressurization of the pipelines by flow reversal and/or a reflected water hammer wave, the vapor cavities will collapse back into solution and the fluid columns will rejoin. When the fluid columns rejoin, very high magnitude pressure spikes will be created that could damage the pipelines. The pipelines may also be damaged by large magnitude negative pressures resulting from the initial pressure drop wave and/or large magnitude high pressures created by a reflected water hammer wave. Simultaneously with the pressure drop wave, a pressure upsurge wave will propagate out from the suction side of the pump station into the gravity flow tunnel toward the deep water intake. If the pressure in the gravity flow tunnel were to increase above the maximum allowable pressure for this conduit, damage could occur. Also, if the pressure in the gravity flow tunnel between the deep water intake and the pump station were to drop below the crown of the pipe harmful negative pressures would develop that would have to be eliminated with appropriately sized vents or other means. Furthermore, if the water level in the wet well was to drop too low it could impact the performance of the pumps when they are re -started. • If the pumps are brought up to speed too quickly, the pipelines downstream of the pump station could be over -pressurized by an upsurge wave while the gravity flow tunnel could experience low or even negative pressures resulting from the creation of a simultaneous downsurge wave. NHC's pressure surge analysis will predict the maximum and minimum HGL envelopes for the gravity flow tunnel, pressure main/tunnel and existing Phase 1 raw water transmission main following pump power failure and pump startup, and will recommend surge control, if necessary, to protect the system from adverse pressure transients. Recommendations will also be provided for safely starting the pumps. Technical Approach for Pressure Surge Analysis NHC proposes to construct a pressure surge analysis model of the system using the TransAM hydraulic transient analysis software. This Method of Characteristics (MCC) based computer model has been used by NHC to perform hydraulic transient analyses of pipeline systems with diameters as large as 22 ft and flow rates up to 1485 cfs. NHC has used TransAM to perform hydraulic transient analyses for the City of Dallas, Metropolitan Water District of Southern California, San Diego County Water Authority, Los Angeles Department of Water and Power, the Southern Nevada Water Authority, BCRUA PHASE 2 DEEP WATER INTAKE Page 8 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal Tm Calleguas Municipal Water District, Irvine Ranch Water District, City of San Diego, City of Stockton, City of Lodi, City of Elk Grove and many other water and wastewater agencies. TransAM has been extensively verified by comparison of computed transient pressures and flows with those measured in the field (e.g., Axworthy and Chabot, 20042) and laboratory (e.g., Axworthy, et al., 20003), and predicted by codes developed by others. TransAM Transient Analvsis Software TransAM is one of the first transient analysis software products to fully exploit the parallel processing capabilities of the multi -core processor and has been used to analyze hundreds of pipelines and distribution systems. The resulting fast computer execution time makes this transient analysis software ideal for performing analyses of large and complex pipeline systems. Scope of Work for 30 Percent Design Pressure Surge Analysis • Extract lengths, diameters, and elevations from the alignment/plan and elevation drawings for the gravity flow tunnel, pressure main/tunnel and existing Phase 1 raw water transmission main, and piping associated with the pump station. Calculate acoustic wavespeeds and Darcy -Weisbach friction 2 Axworthy, D.H. and Chabot, N. (2004). "Pressure transients in a Canadian sewage force main."

BCRUA PHASE 2 DEEP WATER INTAKE Page 9 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal factors for the pipelines. Gather data (e.g., diameters, discharge coefficients, etc.) from manufacturer literature associated with the pumps and valves. Develop pump characteristics for the hydraulic transient analysis computer model using the pump performance curves supplied by HDR. Setup the pressure surge analysis computer model of the system including the pump station, gravity flow tunnel, pressure main/tunnel and existing Phase 1 raw water transmission main, deep water intake, storage tanks, surge relief valves, and pressure reducing valves. • Define the critical operating scenarios for the system. This will involve the definition of maximum and minimum flow rates and hydraulic grade lines, as well as facilities status (e.g., operating, idle, open, closed, etc.) for the primary function of the pump station. Establish hydraulic grade line (HGL) elevations for the tunnels and pipelines under steady state operation and static conditions at the pump station for the critical scenarios. • NHC will use the above initial HGL elevations to perform pressure surge analysis simulations for the operation of the pump station. Simulations will be performed for the critical operating scenarios defined and will include the following: • pump power failure • pump startup • controlled (powered) pump shutdown • Evaluate the results (i.e., predicted maximum and minimum pressures) of the simulations and determine whether or not surge control measures are required to protect the pump station, tunnels and pipelines from adverse pressure transients (e.g., over -pressurization, vapor cavity formation, and large magnitude negative pressures) created by the loss of power and startup of the pumps. • If surge protection is deemed necessary, NHC will determine surge control measures (e.g., diameter and set point pressure of surge/pressure relief valves, diameter and location of controlled venting vacuum relief valves, volume and dimensions of pressurized surge tank, etc.) for the pump station and pipelines. The surge control measures will be designed to ensure that the maximum pressures do not exceed the maximum allowable pressure for the system, and to eliminate the possibility of vapor cavity formation and large magnitude negative pressures in the pipelines following pump power failure and pump startup. The results of the pressure surge analysis with the recommended surge protection improvements in place will also be provided. In addition, recommendations for safely starting the pumps will be provided. • A 30 percent design technical memorandum will be prepared that will include (1) a description of the pressure surge analysis modeling approach, (2) a BCRUA PHASE 2 DEEP WATER INTAKE Page 10 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal description of the physical facilities, including a schematic showing the pressure surge analysis model, (3) component data and assumptions used for the analyses, (4) the results of the pressure surge analyses, including graphical plots of the maximum and minimum HGL envelopes and maximum allowable pressure along the pipeline, and plots of pressure head at the pump station and significant locations on the tunnels and pipelines, etc., (5) recommendations for surge control, and (6) movies of the most pertinent pressure surge analysis simulations. • Quality Assurance/Quality Control review. Following quality assurance review, NHC will provide a draft 30 percent design memo in portable document format (i.e., PDF) to HDR. • Upon receipt of a consolidated set of comments from HDR, NHC will prepare five (5) bound copies of the final 30 percent design memo including CD-ROMs with movies and an electronic version (i.e., PDF) of the final 30 percent design memo. Task 7.3.5 — Physical Hydraulic Model Acceptance Criteria The performance criteria to be used in evaluating the pump station wet well configuration determined in Task 7.2 are based on the Hydraulic Institute 2012 Standards3: Free surface and sub -surface vortices entering the pump should be less severe than vortices with coherent dye cores (free -surface vortices of Type 3 and sub- surface vortices of Type 2). Dye core vortices may be acceptable only if they occur for less than 10% of the time or only for infrequent operating conditions. Swirl angles, both the short-term (10 to 30 second model) maximum and the long-term (10 minute model) average indicated by the swirl meter rotation, should be less than 5 degrees. Maximum short-term (10 to 30 seconds model) swirl angles up to 7 degrees may be acceptable, only if they occur less than 10% of the time or for infrequent pump operating conditions. The swirl meter rotation should be reasonably steady, with no abrupt changes in direction when rotating near the maximum allowable rate (angle). Time -averaged velocities at points in the throat of the bell should be within 10% of the cross-sectional area average velocity. Time -varying velocity fluctuations measured at a point should produce a standard deviation from the time -averaged signal of less than 10%. Model Scale Scale hydraulic models require that the force relationships in the model and prototype are dynamically similar. To achieve this similarity, inertial to gravity, pressure, viscous, BCRUA PHASE 2 DEEP WATER INTAKE Page 11 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal and surface tension forces must be the same between model and prototype; only a 1:1 scale model can achieve these criteria. Modeling at reduced scale involves identifying the primary force relationship to accurately simulate prototype conditions, then selecting a model scale to minimize any scale effects. For free -surface flow conditions, inertial and gravitational forces are the dominant forces that define the hydrodynamic flow conditions. As a result, the Froude number, as defined below, is the key force ratio that must be equal in the model and prototype. That is, F F, Fm 1 F, where, FM = FroudUM e number in the model =— g _LM F, = Froude number in the prototype = U, g LP and, U = characteristic flow velocity g = gravitational acceleration L = characteristic length M = model values P = prototype values Inertial Force Gravitational Force In modeling flow in a pump station structure to evaluate the potential for the formation of vortices, the geometric scale is selected to minimize viscous and surface tension scale effects. Also, the model should be large enough to allow flow visualization, accurate measurements of flow pre -swirl and pump inlet velocities, and sufficient dimensional control. The Reynolds number relates to viscous effects and the Weber number relates to surface tension effects, as defined below. UL Inertial Force Re = Reynolds number= — _ v Viscous Force W =Weber number = pU ZL Inertial Force Surface Tension Force Based on HI (2012)3, the influence of viscous and surface tension forces is negligible if the Reynolds number and Weber number at the model suction bell inlet are above 6x104 and 240, respectively. Based on the above-mentioned scaling criteria, NHC proposes to construct and test a 1:5 scale physical model. This scale will be confirmed once the recommended design is BCRUA PHASE 2 DEEP WATER INTAKE Page 12 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal r tN selected. Adherence to the Froude criterion for dynamic similarity leads to the following range of scale ratios: Model Scale Relationships Parameter Relation Ratio Length Lr 1 :5.0 Velocity Lr 1/2 1 : 2.24 Discharge Lr 5/2 1 : 55.9 Model Description The model will be fabricated to include a section of the 96 -inch diameter inlet conduit tunnel extending upstream at least 10 diameters from the pump station, the junction into the wet well, the wet well configuration determined under Task 7.2, and ten (10) pumps. The wet well will include any support structures that may impact flow to the pumps. For budgeting purposes NHC has assumed that the pumps selected will be vertical turbine pumps. The model will extend vertically 30 -ft (prototype) above the wet well floor. The model basin will be mounted on a raised wooden deck framed with dimensional lumber, and sheathed with clear acrylic plastic to permit visualization of the flow patterns throughout. The pump suction piping will be fabricated from acrylic plastic to permit visualization of the flow in the wet well and pumps, and for dimensional control. Flow will be circulated through the model using a centrifugal laboratory pump with the model inflow controlled using a butterfly valve installed downstream from the laboratory pump. Model inflow rates will be adjusted with a butterfly valve installed in the model discharge lines. The estimated total floor space required for the model (including space for the laboratory pump and viewing) is estimated at approximately 30 ft x 30 ft (900 ft'). Model Measurements The following measurements will be required for the physical model study: Flow Rate - The model inflow rates will be measured in the model supply lines using either an orifice -plate flow meter with an air -water manometer used to measure the pressure differential, or an ultrasonic flow meter. Practicality and ease of model piping will be used to determine which measurement device is best suited for this particular project. Individual pump flows will be determined using elbow meters that measure the pressure differential between the inside and outside of an elbow installed in the discharge line for each model pump. These elbow meters will be calibrated in-place using the orifice -plate flow meter or ultrasonic flow meter. Experience with these BCRUA PHASE 2 DEEP WATER INTAKE Page 13 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal discharge measurement techniques has shown that the measured flow rates are accurate to within two percent. Free -Surface and Subsurface Vortices - Vortices within the wet wells and in the vicinity of the pump bells will be measured by visual observation using dye and will be based on the ANSI/HI 9.8 vortex strength scale. Water Levels - Staff gages will be placed throughout the wet well and screening chamber to provide water level measurements. Water level measurements will be accurate to nearest 0.1 ft (prototype). Flow Pre -swirl - A swirl meter installed in each pump will provide a measure of intensity of swirl. The swirl meters will consist of four neutrally -pitched vanes installed approximately four pipe diameters downstream of the beginning of the instrumentation spool piece. Swirl angles will be computed from the angular velocity of the swirl meter and the axial flow rate. Flow Patterns - Colored dye will be used to document the flow patterns in the wet well and entering the pump bells. Velocity Distribution at the Pump Impeller Location — Velocities will be measured at the impeller location at two pumps. The pump inlet velocities in each modeled pump that has a velocity probe will be measured using a miniature propeller velocity probe and a Pitot tube installed in an instrumentation spool equipped with a turn -column that will allow positioning of the instrumentation at any point in the plane of measurement on a constant radii (8 locations will be monitored). The velocity probe will be connected to a computer that will record the probe readings and display the average velocity (and other statistical values such as standard deviation, maximum, and minimum) over a specified time period (typically 30 — 60 seconds model). Spatial velocity fluctuations will be measured using the Pitot tube by taking the maximum and minimum recorded velocities and dividing by the average velocity using all the measured points. Photographs and Video - Still photographs and video footage will be taken throughout the initial design and final design test phases to provide a visual documentation of the model study progress and key results. Location of Model NHC's laboratories are located in our Edmonton, Alberta; Vancouver, B.C.; Montreal, Quebec, and Seattle, WA offices. The decision on which laboratory will be utilized will be made based on workload, resources, and space availability at the time when the project commences. Testing Initial Design Testing - Upon completion of model construction and shakedown (i.e., tests to ensure that the model is functioning effectively over the full range of operating conditions, and that the instrumentation is properly calibrated and fully functional), BCRUA PHASE 2 DEEP WATER INTAKE Page 14 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK- NHC Updated Proposal model tests will commence with evaluation of the initial design. It is assumed that ten (10) tests will be sufficient to evaluate the initial design over the range of flows specified. The operating combinations include different pump combinations and different water levels. These pump and screen combinations will be developed with HDR. Design Development Testing - Design development testing will be conducted to evaluate possible geometry changes or additions to the initial configuration if unsatisfactory pump performance is identified. Modifications are all expected to be restricted to adding or modifying devices and/or structures within the wet well. Design modifications will be developed in collaboration with HDR as required. It is difficult to predict the number of design modifications that may be required to achieve satisfactory hydraulic performance; however, based on experience with similar studies previously conducted, NHC anticipates that fifteen (15) working days for the Influent Pumping Station will be adequate to develop modifications to meet the acceptance criteria. Witness Test - A one -day witness test of the model study will be conducted for HDR personnel and BCRUA. A "hands-on" demonstration of the model will be conducted. In addition, the witness test will include a presentation of study results, including a brief description of the model construction, scaling and instrumentation, and a summary of the data collected. Two weeks advance notice of the demonstration will be provided to HDR to assist in scheduling. Detailed Documentation Testing of the Final Design - After completion of design development and witness testing, sixteen (16) tests will be conducted to confirm the selected design. It is anticipated that the operating combinations include the same operating combinations used in the Initial Design Testing plus six additional combinations. The actual conditions to be examined in the model will be agreed upon between HDR and NHC at the onset of detailed documentation testing. Reporting NHC will prepare a draft technical report summarizing the model study for review by HDR. The report will contain descriptions of the models, scaling criteria, test procedures, relevant color photographs, and complete descriptions of the test results, including observations, tabular, and graphical data. The report will also provide details (description and drawings) of all modifications and/or additions that were required to correct any hydraulic anomalies or other unsatisfactory flow conditions. The draft report will be submitted in electronic (PDF) format within two (2) weeks of completing the detailed documentation testing. Five (5) bound hardcopies and one electronic copy (PDF) of the final report will be prepared within approximately one (1) week of receiving a consolidated set of review comments. BCRUA PHASE 2 DEEP WATER INTAKE Page 15 CFD, HYDRAULIC TRANSIENTS, and PHYSICAL MODELING SCOPE OF WORK - NHC Updated Proposal 7 All photographic and video documentation will be made available at no additional fee following the test program. As an option, a fully narrated, edited summary video can be prepared for the model study for an incremental charge. The video would include footage of the model, a brief explanation of scaling and modeling methods, and selected footage of initial and final design tests. The summary video would be approximately 15 to 20 minutes in length and provided in DVD format. Long Term Storage Requirement for the Pump Station Model for Final Design From the preliminary design that is developed using the CFD model initially and then using the physical model to optimize the design the design can change. In order to hydraulically assess the impact of the changes a model is required. There are two options: 1) maintain the physical model indefinitely in case the need arises, or 2) calibrate the CFD model with the final design of the pump station from the physical model and use the CFD model to evaluate any future changes. The physical model would then be demolished. Calibrating the CFD model is much less costly than maintain the physical model and that is what HDR selected. Most state-of-the-art CFD software packages, like STAR -CCM+, use a second -order turbulence closure to determined eddy viscosity and mixing, and do not contain arbitrary parameters, except for the roughness height (of walls). The coefficients in the turbulence model are considered global4 and cannot be changed arbitrarily to match field data. Therefore, mesh refinement, adjustment of the roughness height, and switching of turbulence model will be part of the model calibration process. During model calibration step, velocities computed by the CFD model will be compared against data from the physical model. If match between the CFD model and data is not acceptable, roughness height, mesh resolution, and turbulence model will be reviewed and adjusted appropriately. Once an acceptable agreement is obtained, the CFD model will be run for a significantly different operating scenario without any changes, except the boundary conditions. An agreement between the computed results and the second data set will provide a calibrated and validated CFD model. Otherwise, the calibration and validation steps of the will be repeated. It should be noted that accurate and reliable data from the physical model will be very important for this step of the CFD model study. We have assumed that that up to three runs with different mesh refinements, roughness height, and switching turbulence models will be required. A short technical memorandum will be submitted. The calibrated CFD model will be kept through final design of the pump station. If minor changes are made to the design and CFD modeling is required, a level of effort will be provided to undertake the work. If major changes to the design during final design then the physical model may have to be rebuilt and tested. 4 Pope, S.P. (2000). Turbulent Flows.
