CITY OF REDLANDS GEO-LOGIC ASSOCIATES By: B Ga ass, President Pete Aguilar,Mayor Attest: Sauilrwin,616-Clerk 6 1:`Icadjm',Agreements,Ge4o-logic Engineering Services-Phase 3 CA Street Landfill.doe EXHIBIT "A" SCOPE OF SERVICES The following scope ofwork was based onthe outline provided inthe RFP. Task 1: Prepare Phase 3 Liner System Construction Documentation Task 1will consist oxpreparing afinal design report and bid package for the Phase 3Expansion atthe CSL. The bid package will include the Technical Specifications,CQA Plan,and construction drawings.This task has been subdivided into 4 separate subtasks to provide more detail of our work scope. Subtask 1.1 Prepare Phase 3 Design Calculations and Design Report In 2008,Vector prepared the"Joint Technical Document for the California Street Landfill".Contained within the Joint Technical Document(JTD)are the design approach,design criteria, and design calculations that were utilized for the Phase 1 and 2 expansions. Many of these design issues will be similar for the Phase 3 expansion. Having previously completed the design work for Phases 1 and 2 will enable Vector to m*duoo costs and only address specific issues that have changed or are different between the two phases.Vector will prepare urreview the calculations for the design ofthe Phase 3expansion. |tiaanticipated that this will include the following tasks: ° Leachate Conveyance Capacity Calculations:Aspart ofthe Module 3design,Vector will perform leachate modeling. The potential for leachate generation will beevaluated byperforming water balance simulations with the Hydraulic Evaluation of Landfill Performance (HELP)model, Version 3.07. Using HELP,we will be able to produce quantitative estimates of the landfill water balance by simulating one-dimensional profiles cf the cover,waste,LCRS.and bottom liner materials.Key design variables input into the model include the liner system configuration, drainage layer material/permeability,and LCIRS pipe spacing.This information will be calibrated using existing data from leachate quantities pumped from the Phase 1 and Phase 2 sumps. " Leachate Piping Strength and Capacity Calculations. Based onthe results ofthe HELP analysis Vector will verify the leachate collection pipe sizing.Vector will also specify the pipe perforation size, pipe podonnUnn frequency, and leachate collection material. Vector will utilize actual leachate generation data from Phases 1 and 2toassist inthe design ofthe system. The SDR ofall ofthe leachate collection pipes will be specified based on pipe crushing calculations performed assuming the ultimate depth ofwaste |nthe Phase 3area, ° LinerEarthwork Calculations.AutoCAD Civil 3D 2012 will be used for all earthwork calculations for Phase 3. This will allow us to efficiently and accurately develop quantity estimates of the various grading options for the module. For this proposal,Vector has estimated the earthwork quantities for the grading plan asshown inFigure 2inAppendix A. VVeestimate the 1O7.00Oydacfexcavation for the uonnbnohon of the 4 ecns phase depicted in the 2008 JTD. Based on the current incoming tonnages we estimate a life of the phase of approximately 3 years as shown on Figure 3. Aspart of this task,Vector will work with the city to evaluate their current landfill capacity and budgetary needs 8odetermine enappropriate size and configuration for Phase 3. For example.Figures 4and Sshow preliminary grading and fill plans for Phase 3 which will result in a phase life of approximately 5 years. This configuration increases the excavation to 172,000 yd"and the lined area to approximately 6.5 acres. Depending on the needs of the City,constructing a slightly larger phase may be desirable due kzdesign and construction cost savings, * LhmemYRefmom Stability Analysis. Slope stability analyses will be done based on the final configuration.The stability analyses will include anexamination ofboth static and earthquake loading A-7 ccauUmwwncefmmm�Gec-logic sopoeenouServices Phase 3rAnmcet/mndm/,doo conditions. We will evaluate the seismic loading conditions at the site inorder to determine the naepnnue of the landfill mass and cover to the design earthquake. This work will include the examination ofprevious studies performed for the site. Vector will utilize the information naQordingthe seismic hazard analysis, seismic site response analysis,and static limit equilibrium analyses of the cut slopes to perform the ebabo limit equilibrium analyses of the Phase 3 interim waste mass configurations. The results of the liner stability and associated material strength will be incorporated into the Project Specifications and the final analyses will be included in the Design Report. ~ Interim Grading and Surface Water Drainage Plan.Throughout the design ofPhase 3.Vector will consider surface water drainage control and its potential to impact the design of Phase 3 and all future phases. This practice of considering the immediate surface water controls as well as the"big picture" surface water controls at every stage of the design process will help to avoid costly redesigns during the design ofPhase 3and into the future msthe landfill isdeveloped. • Layout myConstruction Staging Areas.VVewill work with the City toidentify areas onthe plans for contractor staging and lay down. This will include temporary stockpile and bentonite admix areas and geosynthoUcyobzraQe. • Incorporate Design Relative toFuture Modules. Our unique and intimate experience with the current JTD will allow us to consider how the configuration of Phase 3 ties into the site development moving forward. Vector will consider how the design of Phase 3 will affect stonnvmatercontrols, access,waste filling, and other activities at the site. ° Prepare the Phase 3Construction Cost Estimate. VVehave considerable experience preparing engineer's cost estimates.Quantities and the basis for individual unit costs will be submitted to the City for review. We recently prepared the engineer's cost estimate for several landfill expansions and has an excellent understanding of contracting costs. Our comprehensive earthworks dasign, construction experience, and access to contractors have allowed us to develop an extensive data base ofconstruction costs for various regions. This knowledge has resulted inaccurate engineer's estimates for our clients. For example,during the design of Phase 2 for the California Street Landfill Expansion our engineer's estimate was less than 1%off of the average of all of the bids and less than 3%off ofthe two low bids. YVeplan tubegin working ondeveloping the engineer's estimate early in the project 10reduce costly redesigns and time delays. Starting the development ufthe construction plana with e schedule of construction unit rates already developed and the beginnings of an engine&s estimate will guide the team towards a design that meets the construction budget and airspace goals. All of the design calculations performed or verified as part of the design of Phase 3 will be compiled into a Design Report for submission to the RWQCB for approval. In addition to having appendices that will include the construction specifications,construction drawings,CQA Plan,and technical calculations and output,the Design Report will likely consist ufthe following sections: 1.0 INTRODUCTION/BACKGROUND 1.1 Project Overview 1,2 Previous Investigations 13 Permit Authority 1.4 Authorization 2.0 LINER SYSTEM DESIGN 2.1 Liner System Components 2,2 Base Grading Plan 2.3 Slope Stability Analysis 2.8.1 Configuration 2.3.2 Method ofAnalysis 2.3.3 yWabaha| Properties /\-0 |:�C^ujmwvgreementsu»m,logicEngineering smices Phase sCxStreet Lamum|.doe 2.3.4 Results of Landfill Stability Analyses 2�3.5 Dynamic Displacement Analyses 2.4 Interim Refuse Grades and Phase Capacity 3.0 LEACHATE COLLECTION AND REMOVAL SYSTEM (LCRS)DESIGN 3.1 General System Description 3.2 Estimation ofLeachate Generation Rates and Liner Head Levels 3.2.1 Selection of Initial Waste Moisture Content 3.2.2 Phase 1 and Leachate Pumping Data 3.2.3 Climatological Data 3.3 Phases 1and 2Analyses and Tie-in 3.4 Phase 3Analyses 3.5 Drainage Layer 3.6 Removal System and Leachate Generation Rates 4.0 SURFACE DRAINAGE SYSTEM DESIGN 4.1 Peak Run-off Determination 4.1.1 Results ofthe Analyses 4.1.2 Drainage Channel Sizing 4.1.3 Culvert and Drop Inlet Sizing 4.2 Peak Run-On Determination 4.2.1 Results ofthe Analysis 4.2.2 Drainage Channel Sizing 5.0 REFERENCES Vector will provide the City with two(2)copies ofthe draft Design Report for review and comment atthe 90% and 90Y6 completion levels.

Questions from the bidders during the pre-bid phase that require addenda to the Specifications or drawings will bediscussed with the City.Once the potential affect(if any)that the addendum will have on the schedule and construction budget is understood by all parties. Vector will prepare submittals with clarifications or A-)} /:1ca"0mwgtmmmmtsm*4--logicsrwiuecru,,oumicesPhase sruuucvtunuax.xnu modifications to the Specifications mdrawings for distribution to the prospective bidders. All inquiries by contractors will only beresponded 0oinawritten format sothat conflicts donot occur. Vector will assist the City inthe review ofbids received for Phase 3construction. The bid documents will require the successful contractor to possess certain minimum,verifiable qualifications.Once the apparent low bidder is identified and agreeable to resolving any pricing conflicts or alternatives, we will contact the applicable references to verify the contractor's qualifications and reputation. Our Project Manager has been responsible for reviewing dozens of construction bids from contractors and is experienced in evaluating documents from contractors. Auaenco Vector will review the bid packages and provide the City with our evaluation and recommendations quickly. Once the bids have been returned and reviewed for completeness,Vector will contact the references of the apparent low bidder. Vector will review the information regarding the project provided by the contractor within the bid. A pre-prepared ranking and qualification form will be used for each reference and details of the conversations will be logged to provide both reliable reference material and defensible documentation in the case that this bidder inrejected onthe basis ofqualifications. During our correspondence,wowill also inquire astothe nature and level ofperformance nfthe contractor's work. Important aspects such asthe ability tu complete the work on time and within the original budget, as well as their ability to work with other parties during project development,will bediscussed. |fthere are any indications that the information provided bythe contractor is inacnuoaha. Vector will contact the contractor and other parties who were involved with the referenced project for clarification. Upon completion ofthe reference check,Vector will provide comments and recommendations mobothe selection ofthe contractor. Once the contract is awarded to the winning oontuactur. Vector will provide engineering services for the duration oJthe Phase 3expansion. This will include attendance at the pre-construction meeting, attending progress meetings oonecessary,and attending afinal job walk. Vector's design team will also beavailable ho review alternatives and change order requests from the contractor as well as Requests for Information(RFIs). In addition,Vector will review and comment on product manufacturer information and contractor submittals if necessary along with the contractors as-built drawings. For proposal purpooeo, we have assumed that the construction period will extend for 120 days. For budgeting purpoaae, we have assumed attendance at6 meetings either otthe site orinthe City offices. Task 3: COA Services durini!the Construction of the Phase 3 Expansion Based on Vector's extensive CQA experience as well as our experience during the previous cell construction at the CSL, several COA issues must be addressed on this project. A listing of the CQA issues that will be handled by our Project Manager and CQA Monitors specific to the Phase 3 construction project include the following: ° RapidKurn'axoumd time for test results. Anon-site field kmbfor soils and geomembnunedestructive testing will be provided.We have over 100 triaxial cells for rapid permeability testing of the subgrade soils and GCL at our Grass Valley laboratory.Precision Laboratories of Garden Grove,California will be conducting the geosynthetics conformance testing.Precision Laboratories was Vector's third party geosynthetics laboratory during the construction of over 100 million square feet of liner systems at other landfills including both the Phase 1 and 2 expansions etthe CSL ° Seam/mgmtgmom,emvbsyne. VVewill observe that seams are free ofmoisture and dirt,proper overlap has been ubbained, proper grinding procedures are followed for extrusion me|ding, and proper squeeze-out from double wedge welds is achieved(excessive squeeze-out from too much pressure weakens seams aadothe presence ofdirt ormoisbre). /\-l2 e"cm0m"Aureenieom'�Go�—mgicEngineering Services, Phase aCA Street umum/,doc ° Data collection.

Prior to installation, conformance testing of the GCL will be performed. Due to the nature of GCL,the proper sampling and handling of the material is critical to successful test results. With conformance test results meeting the required values, Vector's CQA Monitor will verify acceptability prior to the placement of the QCL In addition, we will verify in writing that the soil liner or subgnadeinacceptable 8uthe installer for placement ofliner materials. Our CC>AMonitor will also ensure that all surveys have been performed. During placement, our CDAMonitor will observe that the GOLhas not been damaged o/deteriorated since previous acceptance. Overlapping of each panel will be continuously monitored and observed by our CQA Monitor. The GCLpanels will each have anidentification number placed nnthem bythe Contractor orC{JA Monitor. Our COA Monitor will establish a chart demonstrating correspondence of panel piacament, nuU numbers, certification reports,and panel numbers. Continuous visual observation inaccordance with the CQAPlan will bemaintained throughout the placement and installation ufthe GCL Genmmemnbmanm1mmkmllad1on. Conformance sampling ofthe geomambxaneliner will beperformed prior to installation. The liner materials will be tested in accordance with the C{}A Plan and Specifications. All geomembrane conformance tests will be conducted by Precision.All testing will be performed in accordance with the project Specifications and appropriate test method. Following inspection and acceptance of the GCL,receipt of the manufacturer's quality control certificates,and passing conformance tests from Precision,the Contractor may begin deployment of the geomembrane liner. Our CQA Monitors will observe that the liner is deployed according to the Specifications and that the material iunot damaged during placement. Our CQA Monitors will observe the testing of the seaming equipment and the trial welds. Noseaming can take place until each welder has passed the trial weld and is approved to begin work. VVewill ensure that all seaming is in accordance with the Specifications and the CQA Plan and that no seaming takes place above or below the given temperature requirements. [ngeneral,the nondestructive testing ufseams will bevisually observed by our Monitor and all of the results will be recorded on the liner and on the proper documentation form, For destructive tests,our Monitor will direct the Contractor to take samples every 5OOlinear feet inlocations determined by the Monitors. Additional samples may be necessary if the memnn looks aumpact, weather conditions change,there is wrinkling in the area,or there are a high number of failures in the shear and peel tests. Upon completion of the geomembrane installation, our CQA Monitor will complete a final inspection of the liner, The purpose cf the inspection ietoidentify areas that are damaged orhave wrinkles orfolded material.

In order to visually document the work progress and any problems that may occur, m photographic log will bekept onall activities. Liner Leak Detection Survey CQA We will conduct a leak detection survey on the geomembrane and over the operations layer. Vector currently provides geoelectric leak detection services and is very familiar with the ASTM and field requirements needed to provide o successful survey. In addiUnm, because of our experience performing the auney. our COA Monitors can advise the Contractor during construction on items that will help in providing a successful survey (i.e. adequate moisture in the operations layer and leaving the perimeter geomembnenaexpnned). Vector performed leak location surveys on the Phase 2 liner system at the CSL as part of the regulatory requirements imposed by the Santa Ana RWQCB. Having this capability in-house at Vector streamlined the process and resulted inrapid regulatory approval ofthe Phase 2expansion. Preparation of Draft and Final Reports At the completion of the construction activities,a final CQA report will be prepared and certified by our Project Manager.The final report will consist of a summary of the construction activities,modifications to the design(if any). project CDA field and laboratory hast promedunas, and o compilation of the entire project CQA documentation in on organized report format. Vector will provide copies of the draft final construction certification report to the City for review.Following receipt of any comments,copies of the final stamped report along with adigital copy will beprovided. /\-lQ /:�leauginu\mmeuenmvx,o-|o.-icEuginecri^mServices Phase 3c^Street|auunn.doc Eslvibit8-Project Schaduia t r� ...,., ..a ..- &:_, <:z.:.�s se� zs 5� _ r -";;( arorv<e a,.�a. _____ ____ xs.e,s,;2r.. ..
