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:

Task 2: Enp-ineering Support durint!the Biddin2 and Construction of the Phase 3 Composite Liner System
Vector will work closely with the City during the bidding of the Phase 3 Expansion. We will provide a list of
qualified contractors,assist with distribution of bid documents,respond to bidder inquiries,attend the pre-bid
meeting with potential contractors,prepare written responses to any contractor questions,prepare addenda as
necessary,review and evaluate bid submittals,and provide a written recommendation to the City for award of
contract-
During the pre-bid conference provided for the prospective bidders,we will provide assistance to City staff to
answer technical or administrative questions associated with the proposed construction. We will take minutes
of the conference, prepare an attendance list, and submit the information to the City and interested parties.
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

ASchedule of Testing Frequencies: A table will also be established during review of the project documents,
and included with the Implementation Plan. The table outlines the total number ofCOAtests 0ubmperformed
during construction and will list material types, required testing, and testing frequencies established by the
Technical Specifications orCOA K4onuo{. Estimated quantities from the bid form or material take-off
measurements from the drawings will then be used to determine the actual number of tests to be performed
for each material b4ze or unit of construction. The table will also aid in determining what hamUng will be
performed on-site and what testing will beperformed nff-eda. The table will beupdated with the actual number
of tests performed as the project progresses.A separate,but similar,table will be prepared and maintained for
MOCtesting nfgeosmthetioo.

Mobilize Field and Laboratory Equipment
Vector will provide and furnish a field office/laboratory trailer.The trailer will be equipped with the appropriate
testing equipment hnallow ourCOA Monitor to perform conformance tests on the soil materials for sieve
analysis (O~422).Attarberg limits (O-4318), soil u|oasifioeUon (O-2488). moisture-density relationships (D-
1557). and moisture content (D-2218). 00applicable. The trailer will beused iostore our nuclear density
gauge that will be used for conformance testing of the required in-place densities(D-2922)and moistures(D-
3017). In addition, sand cone density tests(D-1 556)will be conducted to correlate the results of the nuclear
gauge tests.
We believe that as much on-site testing as possible is important to the success of a project of this size and
duration.This enables us to provide fast turn-around time and better feedback to the construction personnel.
It should be noted that we are capable of running all of the required earthworks tests on site withthe exception
of laboratory hydraulic conductivity tests. These tests will be performed at our Grass Valley laboratory.
Our field laboratory will also be equipped with the necessary communication devices such as a fax machine,
copy machine,computer,and intemet.The trailer will also be utilized to house the weekly progress meetings
at the site.

Monitor will keep minutes and distribute them toall designated personnel.
Prepare Daily and Weekly Construction Reports
Our CQA Monitor will prepare a daily record of all construction activities at the site. This daily report will be
used by our CQA Monitor to prepare weekly reports,which will be submitted to our Project Manager and the
City, Along with the daily reports, inspection data sheets will be filled out for any inspection activity or test
procedure. In order to visually document the work progress and any problems that may occur,a photographic
log will bekept onall activities,
At a minimum,our daily reports will include(if applicable)the following information:time on-site,equipmenton-
site,weather conditions, problems/solutions, number and results of tests, and results or comments on any
other CQA activities.Weekly reports summarizing all CQA functions will be submitted to the Project Manager

Evaluation of Low PermeabilitwOn~Site Material
Prior Voplacement of the low permeability layer,Vector's CQA Monitor will observe that the material is suitable
fora low permeability layer byperforming pre-construction testing, All testing will be conducted inaccordance
with the approved CQAPlan.
Engineered Fill Placement CQA
Engineered 0| materials will be tested for moisture and density using a nuclear density gauge. yWo|etuna
content tests will be performed adjacent to the nuclear density tests to verify moisture contents of the
engineered fill. In addition, modified Proctor tests will be performed to assure that the proper compaction
curves are being utilized. Our Monitors will observe the placement of the engineered fill for proper compaction
procedures, lift thickness, and material used.
Low Permeability Layer Placement CQA
Prior to constructing the low permeability layer,the Contractor will construct a test pad(approximately 50-feet
wide by 100-feet long by 2-feet thick). The purpose of the test pad is to demonstrate that the proposed
equipment and construction methodology can achieve the oompac1ion, moisture oon0ert, and hydraulic
conductivity required by the Specifications.The 2-foot thick clay liner will be constructed in a minimum of five
(5)lifts. Upon completion of the test pad and the passing of all CQA testing requirements,the Contractor will
then be nb|a to proceed with construction of the low permeability |ayer, using the same equipment and
methodology that was used hoconstruct the test pad.
During construction of the low permeability layer, our CQA Monitors will perform the following CQA tasks:
~
Observe that the previously compacted lift ioscarified
°
Observe that the maximum compacted lift thickness was adhered tubythe Contractor

After the operations layer has been placed, our [QAMonitor will inspect the layer for low spots or
depressions, areas of damage or improper oompocUon, areas of excessive enzmion, irregularities or
protrusions. All testing ofthe operations layer will follow the requirements ofthe CQAPlan.
Geosynthetic InstaUlationCQA
Geosynthetic Clay Liner(GCL) Installation. 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.
Once the geonn»mbronmhas been accepted, LCRS installation may begin.
GeotextiNeand Geocomposite Installation. As with the geomembrane installation,the inspection activities
for the wahmua gaotaxti|es and Qa000mposiie will be divided into categories consisting of delivery,
conformance testing,installation,field testing and repairs,and final inspection, Conformance sampling ofthe
geotextile and geocomposite will be performed prior to installation,All conformance testswill beperformed by
Precision in accordance with the project Specifications and appropriate test method.

Prior to geotextileand geocompositeplacement, our [QA Monitor will verify grades and make sure the
underlying surface has been prepared and accepted for placement. During installation ofthe 0en1ex1|emand
gmocompoeitmo.our Monitor will inspect the overlap and seaming process for panels.
Our COA Monitor will inspect the geobexU|e and g0000mpoui1e for defects, noed|es, and other foreign
materials,which could damage underlying or overlying materials or could result in the improper function of the
system. We will also ensure that the Contractor does not partake in any activities which could damage the
materials before,during and after deployment.
Conduct CQA Testing and Prepare Data Reports
Inspection data sheets will be filled out for any inspection activity or test procedure. These data sheets will
include, but not be limited to, nuclear compaction test data, field density aummo/y, sand cone density
summary,sieve analysis,Modified Proctor compaction test,Atterberg limits test data,subgrade acceptance,
geosynthetic receiving logs,deployment logs,seaming logs,repair logs,destructive seam test data,and daily
construction reports. 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.
