ATTACHMENT A
PROPOSED SCOPE OF SERVICES
PHASE 1 —TECHNICAL SPECIFICATIONS FOR WELL CONSTRUCTION
Our Phase 1 Scope of Services addresses the tasks necessary to conduct the preliminary de-
sign and drilling contractor selection. Phase 1 will largely be concerned with preparation of well
construction specifications and providing bidding assistance to the City. Currently, we envision
that technical specifications for both wells will be simultaneously distributed to potential bidders
under one set of contract documents.
Task 1.1- Preparation of Technical Specifications & Bidding Documents
Prepare a single set of Technical Specifications and Bidding Documents (Bid Sheets)
for the construction of both wells. These Technical Specifications will entail providing
detailed guidelines for the following aspects of the well construction project:
♦ The drilling and construction methods.
♦ Noise mitigation measures, if applicable.
♦ The estimated pilot hole and casing depths.
♦ The type(s) of downhole geophysical surveys.
♦ The use of deviation surveys in the pilot hole and final casing.
The preliminary design of the wells, including the selection of casing type and
gravel pack.
♦ The use of chemical development for the wells, if applicable.
The duration of mechanical development in each well.
♦ Duration of pumping development.
♦ Final step-drawdown and aquifer testing durations, and flow meter surveys
(spinner logs).
♦ Selection of analytical tests for groundwater samples by the City.
The Technical Specifications and Bid Sheets will be provided to you in electronic format
and can be included within the City's "boiler plate" documents when the project is sent
out to formal bid by your office.
Task 1.2-Estimate of Probable Construction Cost
Prepare a detailed line-item estimate of the probable cost for the construction and testing of the
new wells, exclusive of the pump and aboveground appurtenances. This effort will provide the
2
City with a reasonable expectation of drilling and well construction costs and will form the basis
for realistic comparison of formal bids received from the prospective contractors during the bid-
ding process.
Task 1.3-Assist in Bid Process, Pre-bid Meeting, and Review Bids
Prepare for and attend one pre-bid site meeting with potential bidding contractors for this joint
well construction project. Further, we will provide pre-bid clarifications to bidding contractors
and/or issue addenda, if necessary. Assist the City in assessing bids received.
This task will assist potential bidders in understanding such site logistics as access,
available water supply, location of utilities, and fluids disposal options. In addition, this
meeting will enable the bidders to become familiar with the requirements of the City.
Task 1.4—NPDES Permit(optional)
The California Regional Water Quality Control Board, Santa Ana Region (RWQCB)
oversees and implements the National Pollutant Discharge Elimination System
(NPDES) permit for the U.S. Environmental Protection Agency in the Redlands area.
As such, any de-minimus discharge generated from well development and testing op-
erations to surface water will need to be permitted under the NPDES.
It is understood that the City plans to discharge the development and testing water into
nearby gravel quarry pits. Consequently, there may be no need at this time for an
NPDES permit. However, should a permit be needed, we could assist the City in the
preparation of a NPDES permit for both well sites, as an optional task.
PHASE 2 — FIELD OBSERVATION OF WELL CONSTRUCTION ACTIVITIES
Our Phase 2 Scope of Services addresses the tasks involved with geologic field observation
during well construction activities.
Task 2.1 -Pre-Construction Meeting
Prepare for and attend one pre-construction meeting and review information provided by the
drilling contractor who has been awarded the construction contract for the two wells. Discuss
key issues in the technical specifications. Thus, this task will be to acquaint the City and RCS
with the drilling firm chosen for the project.
In addition, this meeting will better acquaint the drilling firm with the well construction site, to
set-up for the logistical site considerations, such as: nearest available water and electrical sup-
ply; placement of equipment with respect to buried utilities; and disposal of drilling fluids to the
nearby gravel quarry pits. Most importantly, however, will be the driller's responsibility during
3
this meeting to inform City and this consultant what will need to be done to prepare the site for
the required work, when work will actually commence, and to provide to the City a definitive and
detailed schedule for completing the work.
Task 2.2— Conductor Casing and Rkq Mobilization
Provide communication with the Contractor during installation of the conductor casing and dur-
ing mobilization of the drill rig to each site. This task is necessary to help inform the City on the
progress of drilling contractor activities during mobilization. Per the specifications, the contrac-
tor will have the Country inspect and approve this shallow seal.
Task 2.3-Pilot Hole Logging
Because of our knowledge of subsurface conditions in the area, we propose to conduct geo-
logic logging of the pilot hole on a part-time basis from ground surface to a depth of approxi-
mately 800 ft in the first well to be drilled, and then on a full-time basis from 800 ft to the
anticipated 1100-foot depth of the pilot hole for the second well. Based on an anticipated drill-
ing rate of 8 feet per hour, the contractor will require approximately 140 hours (nearly 6 days;
not counting breakdowns or other delays) to attain the desired total depth of 1100 ft. For the
second well, we will geologically log the cuttings on a part-time basis only.
The key reasons why we believe RCS geologists do not have to be present on a full-time basis
throughout pilot hole drilling include:
❑ RCS has already performed a Phase 1 preliminary siting study for these wells.
❑ We have knowledge of local subsurface conditions obtained from prior hydro-
geologic studies conducted for the City.
❑ RCS has numerous electric logs (E-logs) for water wells in the area, virtually all
of which have been correlated into an extensive E-log correlation network.
❑ RCS has geologically logged drill cuttings for several other wells owned by the
City.
During pilot hole logging, we will use standard and commonly accepted and practiced geologic
nomenclature for the drill cuttings. We do not propose to use the Unified Soil Classification
System (USCS) because that system is for engineering application to soils, typically for geo-
technical and engineering geology usage for footings, foundation design, and slope stability.
The UCSC system is not useful for water wells.
When onsite during pilot hole drilling, RCS personnel will review fluid characteristics of viscos-
ity, weight, and sand content to check contractor conformance with the specifications. In addi-
tion to the geologic logging, drilling penetration rates will be collected and plotted on the
geologic log, providing additional subsurface information for hydrogeologic interpretation.
Samples of key formation materials will be obtained during drilling to provide grain-size distribu-
tion curves of these materials to select the final slot size for the casing perforations and gravel
4
pack gradation. Grain-size tests will be performed on representative formation samples for
each well.
Task 2.3 is necessary in providing a detailed geologic log of drill cuttings at the drill site so that
drilling conditions are documented. This necessitates the use of geologists to examine and
record (log) the drill cuttings and to interpret the subsurface geologic conditions as they are
encountered. Documentation of the subsurface geologic conditions provides physical data to
support subsequent analysis of the downhole geophysical surveys of the pilot hole.
Task 2.4—Downhole Geophysical Surrey Log Analysis
Witness and analyze the downhole geophysical survey logs (electric logs) of the pilot
hole at each well site and provide a review of the geophysical log. Review and com-
pare data from geologic logs and electric logs and provide a casing completion recom-
mendation to the driller for the final ream diameter(s) and depth(s) within 48 hours of
receiving water quality laboratory data from the aquifer zone isolation testing in the
open pilot hole.
Geophysical logging is conducted to more accurately determine the depth(s) to possible water-
bearing formations (aquifers), based on their electronic signatures. Geologic logging is often
used as physical evidence to support interpretations made on depth and geologic nature of
subsurface materials penetrated. These data are needed to successfully locate and target
possible water-bearing zones for further consideration such as aquifer-zone isolation testing
and installation of perforated casing at potential water-bearing zones.
Task 2.5-Down-Hole Aquifer Zone Isolation Testing
This task is to conduct aquifer zone isolation testing in the pilot hole of the first well. A
maximum of four (4) aquifer zones will be selected in the pilot hole for the first well
based on review and analysis of drill cuttings and the geophysical survey logs of the
pilot hole. RCS personnel will be present to assist in the sampling and collection of wa-
ter samples from each aquifer zone and will monitor and record, during zone develop-
ment, the field parameters of temperature (T), electrical conductivity (EC), pH, and
turbidity.
A potential aquifer zone, even though it may indicate favorable lithologic conditions for water
production, may also have either acceptable or unacceptable water quality or quantity. Thus,
down-hole aquifer isolation zone testing may need to be conducted to test the feasibility of de-
veloping a chosen zone for water production. Thus, this task is necessary to provide for down-
hole sampling of specific individual aquifers in the pilot hole in order to obtain specific data on
possible concentrations of such analytes as total dissolved solids (TDS), nitrate (as NOA iron
(Fe), manganese (Mn), and boron (B). In addition, it can also be used to check for the pres-
ence of perchlorate (CI04) and volatile organic compounds (VOCs), such as trichloroethylene
(TCE) and perchloroethylene (PCE).
5
Task 2.6- Wells Completion Recommendations and Monitoring of Borehole Ream
Communicate in-progress findings to City and provide recommendations for the Final
well design for each well. Present to City and the driller the Final recommendations for
casing lengths and diameters, well screen placement, perforation sizes (slot sizes),
gravel pack type and gradation, and depth of cement around the blank casing for each
well. These recommendations for the Final well design will be provided within 48 hours
of receiving water quality laboratory data from the aquifer isolation zone testing per-
formed in the pilot hole. No field monitoring of contractor operations during the pilot
hole reams is anticipated; however, daily telephone communications with the driller will
be conducted during the reaming process.
The task is necessary to inform and update City on possible developments occurring during
drilling which might necessitate a change in the well design. Accordingly, we will discuss with
the City the nature of possible changes that may need to be implemented to successfully com-
plete a producing well. This task also serves to provide liaison between the City and the driller.
Task 2.7- Casing and Gravel Pack Installation
A geologist will be present to monitor, on a full-time basis, the installation of the recommended
well screen, blank casing, gravel pack, and cement seal in each well. Monitoring will be con-
ducted to permit conformance with the appropriate methods and materials in the specifications
and/or recommendations based on accurately defined down-hole conditions. Volumes of gravel
pack and cement emplaced are to be monitored and compared with the required volumes cal-
culated from caliper log and casing data in order to help verify a properly filled annulus. During
field construction monitoring, our field geologists will be reviewing the plans and technical speci-
fications for contractor compliance.
In this task, we shall observe and monitor drilling contractor operations in conducting
appropriate and effective methods for casing installation. Further, this monitoring will
also note if the drilling contractor is installing the casing per Final recommendations as
established in Task 2.6.
Task 2.8— Well Development
Provide a geologist, on a part-time basis, at appropriate times to monitor well develop-
ment by both mechanical and pumping methods in each well. This is for the purpose of
observing contractor development operations and check for conformance with Techni-
cal Specifications. Proper mechanical and pumping development of new wells is one of
the most crucial activities during well construction.
6
Task 2.9 -Step-Drawdown Testing
Provide a geologist to monitor step-drawdown testing of the completed wells. Three to four
pumping rates will be recommended and pumping rates and pumping levels will be monitored
on a full-time basis in each well during the step drawdown test. In addition, the water levels will
be monitored continuously in the well(s) during testing with a pressure transducer. This task is
to inform the pumper of step-drawdown testing protocol, monitor his activities so that reliable
information is obtained from testing, and inform City of testing activities.
Task 2.10-Final Aquifer Test(Pumping Test)
Provide a geologist, on an appropriate part-time basis, to monitor water level drawdown and
recovery in the wells during and after the final constant-rate pumping test in each of the com-
pleted wells. Critical times will be those during the first few hours of drawdown and recovery
measurements. Water levels in the wells will also be monitored and recorded continuously
using pressure transducers. Water level drawdown interference between the two wells will be
monitored and defined.
Per the specifications, the contractor's pump crew will also be used to conduct water level
measurements to maintain the monitoring schedule recommended by our office. Field values
of pH, temperature, and electrical conductivity of the well discharge will be obtained on occa-
sion by the geologist during the test. Water samples of the final well blend from each well will
be collected for quality testing by City.
At the end of the aquifer testing, we will have the contractor perform a flow meter (spinner log)
survey of each well to identify the present flow capacity regime of the various perforated zones
in the well. Our technical specifications will provide for an appropriately sized camera
ports/sounding tube to permit this survey in the wells.
The purpose of this task is to collect accurate and reliable aquifer test data. Such data are im-
portant to provide an adequate analysis of aquifer transmissivities, the production capabilities of
the wells, and the amount of water level drawdown interference between the wells. These data
are used in conjunction with water quality data to establish the final well blend water sample
quality in the wells. Field monitoring of water levels in the new wells during aquifer testing is
useful in determining long-term drawdown in the vicinity of the wells.
Task 2.11 - Casing Alignment Testing and Video Log Survey
Review data obtained from the prescribed insertion of a casing dummy or cage and
monitor deflection readings for the alignment/plumbness testing of the wells. Assess
results of the testing in view of the specifications. In addition, we will review the video
survey of each well.
7
This task is to monitor the activities of the drilling contractor as the casing alignment testing is
being conducted and to check that the video survey log is of sufficient quality to reliably docu-
ment as-built wells conditions.
Task 2.12-Summary of Construction Operations Report
Provide hydrogeologic analyses of field and laboratory data obtained during well drilling, con-
struction, and testing at each of the two drill sites. The individual Summary of Construction
Operations Report for each well will summarize the existing geologic conditions such as the
subsurface lithology, aquifer zones where well perforations have been set, and interwell correla-
tion of aquifers based on downhole geophysical logs. In addition, water level drawdown data
collected during aquifer testing will be used to determine aquifer transmissivity at each well site.
Provide three copies of each report to summarize well construction activities and to provide an
"as-built" of the completed wells, along with a lithologic (mud) log, geophysical logs, water qual-
ity laboratory test data, and aquifer test data. Data acquired during the logging and testing of
the wells will be included also. Recommendations for operational yield and final pump place-
ment will also be provided.
The purpose of this task is to help document the drilling, construction, and testing activities of
the new wells. Further, future examination of well conditions and/or construction operations will
be facilitated through reference to the Summary of Construction Operations report.
Task 2.13—P*Wect Management, Review Contractor Submittals, and Meetings.
We will provide the project management and associated technical oversight activities by
attending three (3) meetings with the City during the project, by reviewing contractor submittals
during the project, and by reviewing Contractor progress invoices to the City for accuracy and
consistency.

ATTACHMENT B
PROJECT SCHEDULE
Based on the above Scope of Services, and following receipt of a written notice-to-
proceed from the City, we submit the following estimated time schedule for conducting
the work:
Phase 1 Technical Specifications for = Week 0 —Week 4
Well Construction
Phase 2 Field Observation of Well = Week 4 —Week 8,

ATTACHMENT C
PROJECT COSTS
For the proposed project, we estimate the total cost for our professional services for the
above outlined Scope of Services for both wells to be as shown below:
Phase 1 —Technical Specifications for Well Con- $11,750.00
struction
Phase 2— Field Observation of Well Construction $97,600.00
Activities
Use of in-house water quality and water level $1,100.00
equipment, and pressure transducers
Total Proiect Estimate: $108,350.00
The amount shown can be considered as a not-to-exceed amount. It should be noted
that because the exact number of hours required to complete the different tasks of well
construction (Phase 2) is outside the control of the consultant, we recommend that all
construction monitoring be performed on a time and expenses basis, and that if the
time required to complete Phase 2 is expected to exceed our estimates once construc-
tion is underway (as, for example due to unusually slow drilling, numerous contractor
breakdowns, or difficulties in meeting discharge quality requirements), we will notify
your office.
The above estimated cost is based on the following key assumptions:
1. Pilot hole drilling for each of the proposed new City wells is estimated, for the
purposes of this proposal, to be to a maximum depth of 1100 ft bgs.
2. The overall drill rate is expected to be on the order of eight (8) feet per hour for
drilling the pilot hole, thus requiring the contractor to expend approximately 140
hoursof drilling for the wells. Drilling is to be performed on a 24-hours-per-day
schedule. We estimate the total number of hours for our field personnel on a
part-time basis to 800 ft and then on a full-time basis from 800 ft to 1100 ft on
the first well and on a part time basis for all of the nearby second well to be on
the order of 170 hours for geologic logging of both pilot holes.
3. Aquifer zone isolation testing will need to be conducted in the pilot hole for the
first well. We estimate that a maximum of four (4) aquifer zones will be targeted
for sampling and our cost estimate is based on that assumption.

4. [)bSerVaUOO of installation Of the Vv8Us casing, the g[3Ve| pack, and of the Ce-
ment annular seal by ourfU||-tiD1e field personnel is estimated to require ap-
proximately 75 hours for each well.
5. Mechanical and pumping d8Ye|OpDleOt of the wells will he performed OO a part-
time basis. ThUS, it is estimated that our field personnel will expend approxi-
mately 80 hours during this period at both VY8||S. Because the discharge from
the wells per the City is to be to nearby gravel quarry pitS, then y4@tioD@| Pollut-
ant Discharge Elimination System (MPDES) permit monitoring will not be
needed.
8. Step-drawdown testing will be DlODitO[Sd by our field personnel on a fUU-UrD8
basis and the constant rate testing will be 0OOitO[8d On 3 part-time b8SiS.
thereby requiring approximately 7Ohours Ofour personnel time, total.
7. Casing alignment testing, the video survey and chlorination Ofthe wells will be
monitored by our personnel on a part-time basis and is estimated to require ap-
proximately 16 hOU[S Ofour field p8nSOOO8| time.
8. The City, Or the ContngctOr. will pay directly for all laboratory 03SiiDg Of water
oannp|eS collected by our firm from the down-hole aquifer zone isolation heating,
in the first well, and from the final well testing after construction of each well has
been completed.
Our services will be billed OO 8 d[D8-aOd-eXp8OS8 basis and in accordance with our current
Schedule ofCharges shown nnAttachment []. However, the cost estimate for the above scope
of work is virtually entirely dependent on such third-party operations as: the drilling method e[D-
p|Oy8d, the drilling rate for the pilot hole, and the time required for casing DODlp|etiOD and wells
development.
