SUBJECT:
Authorize Execution of Amendment No. 2 to City Secretary Contract No. 28977 with CH2M Hill, Inc.,
for Southside II Water Main Transmission Main from Rolling Hills Treatment Plant to the Crowley
Road/Risinger Road Intersection (City Project No. 00303)
RECOMMENDATION:
It is recommended that the City Council authorize the City Manager to execute Amendment No. 2 to City
Secretary Contract No. 28977 with CH2M Hill, Inc., in the amount of $259 600.00 to provide additional
engineering services on the project, thereby increasing the contract amo ntfi t 2,249.00.
DISCUSSION:
On July 29, 2003 (via M&C C-28977), the City Council authorized the City Manager to execute an
agreement with CH2M Hill, Inc., in the amount of $613,449.00 for the design of Southside II Water
Transmission Main from Rolling Hills Treatment Plant to the Crowley Road/Risinger Road intersection. The
agreement was subsequently revised by one previous amendment in the amount of$8,700.00 that allowed
for the preparation of a surge modeling analysis for protection of the water main.
The project includes design for the installation of a 48-inch water main on Risinger Road from Crowley
Road to Oak Grove Road and a 54-inch water main on Oak Grove Road from Everman Road to the Rolling
Hills Water Treatment Plant.
Amendment No. 2 will address the following:
. The realignment of the 48 and 54-inch water mains in order to accommodate the alignment proposed
for the future Risinger Road and avoid conflicts with previously unknown and recently installed private
utilities located within the project area. In conjunction with the water main realignment, several
existing water mains that cross the new alignment will be connected to the proposed mains; and
. The removal and relocation of an existing 16-inch water main currently located on Risinger Road in
order to eliminate conflict with the proposed water main and accommodate the future alignment of
Risinger Road; and
. The installation of a 12-inch water main on the west side of Crowley Road from Risinger Road to
Quarter Horse Drive, in order to create a looped system as requested by the Water Department; and
. The separation of the project plans and specifications into four individual units to allow for multiple
contracts and expedite construction of the project.

Subject: Southside II Water Transmission Main from Rolling Hills WTP to the Intersection
of Risinger and Crowley Roads Proposal for Additional Services
Amendment No. 2
Dear Mr. Domenech:
The purpose of this letter is to request authorization to perform additional services for the
Southside II Water Transmission Main Project as described herein in the amount of$259,600
and detailed in the attached two exhibits.
Task I-Additional Easement Preparation and Survey Services
During the original contract scoping,CH2M HILL was directed to design the Transmission
Main in the existing road right of ways. The original contract provided fees for up to 12
temporary and permanent easements on the project. During Preliminary Design, the City
directed CH2M HILL to align the transmission main outside of the existing street right of
ways,which resulted in additional permanent and temporary easements. To date,
CH2M HILL has prepared nineteen(19) easements between Old Burleson Road and the
Rolling Hills WTP. We request reimbursement for preparation of the additional 7
easements (already completed)by our subconsultant, Leonard Technical Services (LTS)
which were not included in the original Contract. In addition,out of scope survey services
were provided in working with,coordinating, and surveying DeHole locations on the
project.
The estimated fees for Task 1 are:
Design $0
Survey $10,648
Total $10,648
Task 2-Preparation of Memos and Documents.
This task is for reviewing alignments,preparing alignment alternatives layouts,cross-
sections, and memos that were used to coordinate with the City in determining alternate
alignment options for the Southside II WTM. This includes CAD work, design eff

preparation of multiple memos. This effort resulted from the conflict with the developer-
installed water line on the south side of Risinger Road, and from the conflict with the newly
installed overhead electric transmission along Oak Grove.
The estimated fees for Task 2 are:
Design $19,428
Survey $0
Total $19,428
Task 3-Meetings.
This task includes fees for additional meetings and preparation of meeting minutes
necessary to coordinate the design changes with the City. The memos and documents
prepared in Task 2 were presented and discussed in these meetings to finalize alternative
route options.
The estimated fees for Task 3 are:
Design $8,226
Survey $0
Total $8,226
Task 4- Risinger Road- Realignment of the 48" Pipe from Crowley Road to Oak Grove
This task includes fees necessary for the redesign of the pipeline based on recent revisions in
alignment. The alignment was revised to accommodate existing utilities, recently installed
utilities,and the future Risinger Rd alignment. The revised alignment places the 48" pipe
approximately 5 feet south of the proposed future Risinger Rd centerline,between Crowley
and IH35.Going east of IH35,the pipe will be installed approximately 5 feet north of the
proposed centerline of the Risinger extension(beyond Old Burleson) to Oak Grove Road.
Design of the originally proposed alignment was completed to approximately 90% design-
level,and easements for the alignment were prepared and submitted for use by the City in
acquiring the property. The re-alignment will result in additional survey and utility
research,horizontal and vertical alignment changes,air valve and isolation valve
relocations,thrust restraint design changes,revisions to the SWPPP and traffic control plans,
and additional survey and easement preparation.This task include survey of up to 8
Deholes, a monumentation survey from Crowley Rd. to Oak Grove Rd.,full topographic
survey and basefile creation between Old Burleson and Oak Grove (max 5,000 l.f.),
determination of utility locations (from records and surface features only), and preparation
of up to 6 easement documents. This task also includes preparing 6 new paving plan
drawings showing centerline and edge of pavement locations and elevations,along with a
typical pavement section,for pavement replacement along Risinger Road between Crowley
Road and IH35.
Additionally, since the City requested multiple connections between the proposed
transmission main and existing distribution and transmission mains, the surge model will

be modified and adjusted for this condition. All changes resulting from the re-alignment
and surge analysis will be incorporated into the project Specifications.
The estimated fees for Task 4 are:
Design $59,789
Survey $18,730
Total $78,519
Task 5 -New Water Distribution Pipe,Risinger Road
This task includes effort required for the design and specifications for removal of the
existing 16" water line in Risinger, and replacement with a new distribution water pipe
(anticipated diameter is between 8" and 16") offset approximately 30 feet north of the
proposed 48" diameter transmission main. The 16" water line is being removed and
relocated to accommodate the future Risinger Rd alignment and the 48" water line
alignment. The distribution line will begin near the start of the 48" transmission main,
extend east along Risinger to IH35,and turn north for approximately 1,150 feet along the
IH35 frontage road (southbound) to a connection point to be designated by the City. This
task will require full topographic survey and basefile creation along the stretch of IH35 (max
1,5001.f.), determination of utility locations (from records and surface features only), survey
of up to 2 Deholes, and preparation of up to 3 new easement documents. This task will also
include necessary SWPPP and traffic control design in the IH35 area.
The estimated fees for Task 5 are:
Design $33,714
Survey $5,133
Total $38,847
Task 6-New Water Distribution Pipe, Crowley Road
This task includes the design and specifications required for installation of a 12" diameter
distribution line along the west side of Crowley Road to create a looped distribution system.
This new design will require full topographic survey and basefile creation along this stretch
of Crowley Road (max 2,000 Lf.), determination of utility locations (from records and
surface features only), survey of up to 2 Deholes,and preparation of up to 3 new easement
documents. This task will also include necessary SWPPP and traffic control design.
Estimated fees for Task 6 are:
Design $13,314
Survey $7,413
Total $20,727

Task 7- Oak Grove-Realignment of the 54" Pipe, Everman to Rolling Hills WTP
This task includes the redesign of the pipeline based on recent revisions in alignment. The
revised alignment places the 54" pipe on the west side of Oak Grove Road from just south of
Everman to Altamesa Blvd. At Altamesa, the main will be installed in the northbound lanes
of Oak Grove/Campus Drive until approximately reaching the existing 48" water line. At
that point, the 54" water line will revert back to the alignment proposed in the 75% design
drawings. The alignment was revised to avoid conflicts with recently installed utilities and
to avoid easements.These changes result in a realignment of approximately 12,600 feet of
54" pipe. Design of the originally proposed alignment was completed to approximately 90%
design-level, and easements for the alignment were prepared and submitted for use by the
City in acquiring the property. Re-alignment will result in additional survey and utility
research,horizontal and vertical alignment changes,air valve and isolation valve
relocations,and thrust restraint design changes.This task includes survey of up to 10
Deholes, re-establishing survey control from Everman to Altamesa, survey of property pins
and additional surface features/utility features that may have been installed since the
previous survey, verification of utility locations on the west side of Oak Grove between
these same extents (from records and surface features only), and preparation of up to 2
easement documents. This task also includes revision of the previously designed SWPPP,
and preparation of traffic control plans as required based upon the revised alignment.
The estimated fees for Task 7 are:
Design $45,926
Survey $3,220
Total $49,146
Task 8-Divide into 4 Project Units
This task covers separating the project into 4 Units,as opposed to the current 2 Units.
Implications resulting from the division into 4 Units include:
- Additional "front-end" drawing sheets for 2 new units (cover sheet, site plan,
location plan,control point plan,easement plan, alignment data sheet)
- Modification of the existing front-end drawings on the original 2 units
- Division of existing drawing sheets (plan/profile,SWPPP,traffic control,etc.) into
additional units.
- Modification of Specifications and creation of additional Proposal Forms
- Additional bidding services and additional services during construction
The estimated fees for Task 8 are:
Design $27,415
Survey $0
Total $27,415 l a

Task 9- Drainage Study
This task covers engineering analysis of larger-scale drainageways that the pipelines may
cross. The goal is to determine approximate horizontal location and depth of drainage
structures (culverts) that may installed in the future during roadway
construction/expansions,with the desire to bury the transmission main sufficiently deep
that no relocation is necessary with future road construction. This task covers hydrologic
and hydraulic evaluation of the following seven (7) major drainage courses only: Sta 5+00,
Sta 7+25,Sta 115+00 (new segment of Risinger),Sta 193+00,Sta 273+25,Sta 279+60,Sta
317+40;This does not include the following existing smaller-scale and/or lined drainage
courses:Sta 180+00,Sta 239+50,Sta 251+50. Stationing of these locations is according to that
reflected in the 75% plan set submitted in August 2004.Hydrologic evaluations will consist
of conceptual level watershed acreage delineation using City-provided NCTCOG aerial and
topographic maps using the Rational Method for one storm event. General assumptions for
runoff coefficient,time of concentration,and storm intensity will be used (i.e.C=0.65 and Tc
=20nin-25min). Hydraulic evaluations will consists of sizing a culvert to pass the 100-yr
storm below the crown of road based on an assumed maximum velocity through the
culvert. No ground survey will be performed in relation to this task.
The estimated fees for Task 9 are:
Design $6,644
Survey $0
Total $6,644
General
The project currently is stationed from Crowley Road to the WTP. In preparation of this fee
estimate, the project will be separated into 4 Units,but it has been assumed that there will
be no re-stationing of the project in the opposite direction. Stationing will occur in the same
direction as reflected in the 75% drawings,but will be updated based upon the revised
project alignment.
