the Project, and recommend to the Owner as to the proper action on all
proposals received.
3. Assist in the preparation of formal Contract Documents for the contracts.
4. Make periodic visits to the site (as distinguished from the continuous
services of a resident Project Representative described in Subparagraph 6
below) to observe the progress and quality of the executed work and to
determine in general if the work is proceeding in accordance with the
Contract Documents. In performing this service, the Engineer will not be
required to make exhaustive or continuous on -site inspections to check the
quality or quantity of the work or material; he will not be responsible for the
techniques and sequences of construction or the safety precautions
incident thereto, and he wit not be responsible or liable in any degree for
the contractors' failure to perform the construction work in accordance with
the Contract Documents. During visits to the construction site, and on the
basis of the Engineer's on -site observations as an experienced and
qualified design professional, he will keep the Owner informed of the extent
of the progress of the work, and advise the Owner of material and
substantial defects and deficiencies in the work of contractors which are
discovered by the Engineer or otherwise brought to the Engineer's attention
in the course of construction, and may, on behalf of the Owner, exercise
whatever rights the Owner may have to disapprove work and materials as
failing to conform to the Contract Documents.
5. Consult and advise with the Owner; issue all instructions to the contractor
requested by the Owner, and prepare routine change orders as required.
6. If specifically authorized by the Owner in writing, fumish the services of
resident Project Representatives, and other field personnel for continuous

usual degree of care and prudent judgment in the selection of competent
Project Representatives, and the Engineer will use diligence to see that the
Project Representatives are on the job to perform their required duties. It is
agreed, however, that the Engineer does not underwrite, guarantee, or
insure the work done by the contractors, and since it is the contractors'
responsibility to perform the work in accordance with the Contract
Documents, the Engineer is not responsible or liable for the contractors'
failure to do so, and, so long as Engineer has exercised the usual degree of
care and prudent judgment in selecting Project Representatives and has
used diligence to see that they are on the job to perform the work, failure by
any Project Representatives or other personnel engaged in on- the -site
observation to discover defects or deficiencies in the work of the contractors
shall never relieve the contractors of liability therefore or subject the
Engineer to any liability for any such defect or deficiencies.
7. Review samples, catalog data, schedules, shop drawings, laboratory, shop
and mill tests of materials and equipment and other data which the
contractor is required to submit, only for conformance with the design
concept of the Project and compliance with the information given by the

PRELIMINARY PHASE SCOPE OF SERVICES
General Description of Work: Engineer will gather current data and update the
information in the Owner's existing water distribution computer model. The model will
also be converted to the EPANET software package. The updated EPANET model will
then be used to evaluate the entire City water distribution system and identify areas with
inadequate or questionable water service. Various altematives improvements to correct
low water pressure in the problem areas will be developed, specifically in the known low
pressure areas in the vicinity of the intersection of Interstate Highway 35 and Farm to
Market Road 1325. Permit issues will b.e investigated and opinions of probable
construction cost developed for each of the altematives. The model update and
improvements analysis will be summarized in a report submitted to the Owner.
Task 1 - Compile Data: Engineer will meet with Owner to compile data necessary to
conduct the water distribution system evaluation. It is anticipated that the Owner will
provide copies of the existing water system computer model, computer model node map,
billing records, water connection records, water usage records, building permit
summaries, available population data, water utility maps, as- built/construction drawings of
system improvements not included in existing computer model, fire flow requirements,
and water system information such as sizes and capacities of pump stations, storage
tanks, and pipelines.
Task 2 - Conversion of the Existing Model to EPANET. Engineer will convert the existing
distribution system model to the EPANET software package and make necessary
refinements to execute the model.
Task 3 - Update Computer Model Geometry: Engineer will update the geometry and
system characteristics in the existing water distribution computer model with the available
current system characteristics (capacities) and pipeline geometry (as- built/construction
drawings).
Task 4 - Update Computer Model Demands: The available billing records, water use
data, connection data, and population information will be used to evaluate the change in
peak day water demands in the City since the existing model was developed and to then
develop a ratio /factor to update the demands to present day. The basic distribution of
demands in the existing model is assumed to be acceptable. New demands will be
estimated for the areas with new development not currently reflected in the model. In
addition, the City's fire flow requirements will be evaluated to determine appropriate fire
demands to be used in the study.
Attachment 4 (continued)
Task 5 - Existing Conditions Model: The updated peak day water demands will be input
into the model along with the revised system geometry to form an existing conditions
model. This model will be executed in static simulations of the water system and the
results compared to known and estimated field conditions. One day of current field data
during high demand, summertime conditions will be requested from the City to assist in
calibrating the model. The model will be executed with simulated fire demands at various
locations in the system in order to define areas with inadequate or questionable service.
Task 6 - Development and Evaluation of Altematives: Altemative solutions to improve
water service to each of the problem areas identified in the Task 5 will be developed. The
existing conditions model will be revised to simulate the altemative solutions. The
simulations will evaluate system performance under peak day plus fire demands and
evaluate system pressure and storage requirements. For the area surrounding the
intersection of IH 35 and FM 1325, the following altematives to be investigated include:
• Construction of a pipeline under IH 35 to connect a portion of Pressure Plane 4 to
Pressure Plane 2.
• Construction of a pipeline under IH 35 to connect of a portion of Pressure Plane 4 to
the pipeline from the City of Austin's Martin Hill Reservoir.
• Construction of water storage and a booster pump station east of IH 35 to create a
new pressure zone.
Task 7 - Investigation of Permit Issues: Engineer will contact appropriate entities
conceming possible permitting issues associated with each feasible altemative in order to
determine project requirements. Possible permit issues include highway crossings, City
of Austin supply modifications, and construction over the Edward's Aquifer Recharge
Zone. Anticipated contacts include the Texas Department of Transportation, City of
Austin, and the Texas Natural Resource Conservation Commission.
Task 8 - Preparation of Opinions of Probable Construction Cost: Opinions of Probable
Construction Cost will be prepared for each of the feasible altematives evaluated. The
Opinions will include construction, engineering, related services, and contingencies.
Task 9 - Preparation of Report: The results of the evaluation and a recommended set of
improvements will be summarized in a report submitted to the Owner for approval. The
report will include background information regarding the model development and
updating procedure as well as graphic output from the EPANET model.
DATE: July 22, 1996
SUBJECT: City Council Meeting, July 25, 1996
ITEM: 10B. Consider a resolution authorizing the Mayor to execute an agreement with HDR
Engineering, Inc. for the Water System Pressure Improvements.
STAFF RESOURCE PERSON: Jim Nuse
STAFF RECOMMENDATION:
This agreement will provide three services:
Convert and update water model to reflect current system and to put model on a user -
friendly format. The current KYPIPE model is bulky. EPANET is a superior model.

Re: Proposal for Engineering Services
Water System Pressure Improvements
Dear Mr. Bennett:
Enclosed please find a Draft Agreement for Engineering Services submitted as a proposal for a
project to evaluate the City's water distribution system, identify inadequate service areas, and
implement improvements in these areas. This proposal is sent in response to a request by the
Public Works staff for an investigation of reported pressure problems in the area surrounding the
intersection of lH 35 and FM 1325.
Our understanding is that the City has been receiving reports of low water pressure in portions of
Pressure Plane 4, specifically the area east of IH 35 along Louis Henna Boulevard around the
new Dell Computer complex. Based on our preliminary review of the City's distribution system
and our discussions with the Public Works Staff, we have found that the area experiencing
pressure problems, along with areas in Pressure Plane 2 shown in the attached figure, are quite
high in elevation in comparison to the operating pressure maintained in Pressure Planes 2 and 4.
As shown in the attached figure, our preliminary review of the City's system indicates that the
maximum pressure which can be achieved at the surface of the ground with all storage tanks full
and no water demand is less than 50 pounds per square inch (psi) in a significant portion of the
area and 40 psi in isolated locations. These pressures are estimated to decrease by 5 to 15 psi
during a normal day due to water demands and fluctuations in tank levels. Assuming the fourth
floor of a four story building is forty feet above the ground surface, the maximum available
pressure during a normal day could be expected to be 20 to 30 psi, without the losses normally
found in building plumbing. In comparison, the minimum water system operating pressure
required by the Texas Natural Resource Conservation Commission is 35 psi under normal
conditions and 20 psi during an emergency fire flow situation.
Since the area in question is a strong growth area of the City and contains a large concentration
of retail and multi -story development, we recommend that a thorough evaluation of water service
in this area of the system be conducted to determine the most cost effective improvements to
maintain adequate pressure under all conditions, including an emergency fire flow situation.

The City has an existing computer model of the water distribution system which could be
updated and used to conduct this analysis. However, our understanding is that the input data in
this model is outdated due to recent growth in the system. In order to properly evaluate the
known pressure problems along Louis Henna Boulevard, Pressure Planes 2 and 4 of the City
model would have to be updated. These two pressure planes comprise approximately one -half of
the City's system. If a project of this magnitude is to be undertaken, we recommend that the
model for the entire City system be updated and developed into an up to date, usable planning
tool that the City can use for the evaluation of the water system and for future projects.
Therefore, the scope of services we propose as the Preliminary Phase in the attached Agreement
includes conversion of the entire City water distribution computer model to the more interactive
and user friendly EPANET software package. The analysis capability of the EPANET model is
much better than the existing KYPIPE model, and will result in a computer model of the City's
system which is a usable tool for future system evaluations. The EPANET model will be
updated to reflect the current piping arrangements and demands in the City. The model will then
be executed to identify areas of the City with questionable or inadequate service and develop
alternative improvements in these areas. The improvements will specifically address the known
low pressure areas along Louis Henna Boulevard and will include the following alternative
solutions:
• Construction of a pipeline under III 35 to connect a portion of Pressure Plane 4 (east of 1H
35) to Pressure Plane 2 (west of EH 35), which operates at a pressure about 20 psi higher than
the pressure in Pressure Plane 4. The effects of a large fire demand on the interconnection
under the highway will be evaluated along with the residual pressure at the high elevation
areas during an emergency situation. Since the required storage in Pressure Plane 2 will be
effected if a portion of Pressure Plane 4 is moved to Pressure Plane 2, the storage capacity in
both pressure planes will be evaluated to determine if there is adequate storage to maintain
the required 20 psi pressure under fire flow conditions.
• Construction of a new pipeline under IH 35 to connect to the higher pressure supply from the
City of Austin's system and Martin Hill Reservoir. The City of Austin pressure ranges from
25 to 40 psi higher than the current operating pressure in Pressure Plane 4. This alternative
would provide a means to serve future development south of FM 1325 and in the
undeveloped low pressure areas now in Pressure Plane 2. This alternative may require
coordination with the City of Austin if the existing water meter location is affected.
• Installation of water storage and a booster pump station on the east side of IH 35 to raise the
pressure in the problem area. This alternative would create a new, separate pressure plane to
serve the localized pressure problems in Pressure Plane 4 along Louis Henna Boulevard. The
capacity of the pump station, the storage tank size, and the operating pressure of the new
pressure plane would be determined by the computer model.

The final product of the Preliminary Phase will be a report summarizing the methodology used to
update the model and the results of the system evaluation. This report will identify the
recommended improvements required and the associated estimated costs. Engineering costs to
complete the Preliminary Phase will be billed on a per diem reimbursable basis in amount not to
exceed $48,806.
At the conclusion of the Preliminary Phase, HDR will be able to determine the engineering effort
required to prepare construction documents, provide bidding assistance, and construction
administration in order to implement the recommended improvements. Upon approval of the
report by the City, HDR will then submit a proposed amendment to this Agreement to include a
detailed scope of services for the Design and Construction Phases.
The attached Agreement is submitted in Draft form. Please review the document and return any
comments you may have to us. We truly appreciate having the opportunity to provide this
proposal to the City of Round Rock. Should you have any question or need additional
information, please call.
