The cost of the study is not to exceed $9,700
without written approval. Funds are budgeted
in the Dublin Boulevard/Silvergate Drive
Intersection Modification Capital Improvement
Project for this purpose.
DESCRIPTION: A project is included in the current Capital
Improvement Program (CIP) which will modify the Dublin Boulevard/
Silvergate Drive intersection into a "T" intersection, with Dublin
Boulevard being the through street. The first phase of design for
this project is to obtain specialized geotechnical services. The data
prepared under this agreement will be utilized by the design engineers
to complete project plans and specifications.
Dublin Boulevard is constructed on a fill embankment between Hansen
Drive and Silvergate Drive. Numerous longitudinal cracks have
developed on this section of Dublin Boulevard. Geotechnical
investigation is needed to assess the subsurface condition beneath the
pavement in order to determine the reason for the cause of distress
and to recommend mitigation. The investigation will also include
recommendations for fill materials, compaction requirements, cut and
fill slope stability considerations, pavement design parameters, and
alternative pavement sections for the added lanes and possible
replacement of existing pavement.
On July 24, 1991, the Public Works Department received four (4)
proposals from local qualified engineering consulting firms. After
reviewing all four proposals for past performance, experience,
knowledge of the area and site, ability to complete the project in a
short time, and equipment and staffing, Staff considered Berlogar
Geotechnical Consultants best able to fulfill the City's requirements.
After choosing Berlogar as the consultant, Staff opened the fee
proposal packages and found Berlogar's fees to be in line with the
scope of work to be performed. In accordance with State Law, the
selection of engineers and architects and other specified services
must be based upon qualifications rather than bid prices.
Staff will have an item on a future agenda regarding the selection of
an engineering design firm to prepare plans and specifications for
this project. The geotechnical services will result in
recommendations which will be incorporated into the final design. DUe
to the specialized nature of geotechnical services, it is typical to
utilize two different consultants for this type of work.
staff recommends that the City Council adopt the resolution approving
the agreement with Berlogar Geotechnical Consultants.

Subject:
Proposal
Geotechnical Investigation
Dublin Boulevard
Between Hansen Drive and Silvergate Drive
Dublin, California_
Dear Mr. Thompson:
We are pleased to present this proposal to perform a geotechnical
investigation for the subject site. This proposal is in response
to your ,,Request for Proposal" (RFP) letter submitted to our
office. We previously submitted a proposal to perform a pavement
distress investigation for Dublin Boulevard, dated November 5,
1989. According to your "RFP" Dublin Boulevard will be widened
between Hansen Drive and approximately 400 feet west of Silvergate
Drive and the intersection with Silvergate Drive will be
reconstructed. The existing road is about 15 to 20 years old and
is constructed on a fill embankment ranging in height from about
5 to 25 feet. During a visit to the site prior to the preparation
of our initial proposal letter, we observed numerous longitudinal
cracks in the pavement with most of the cracks on the northern side
of the east-west trending roadway. At that time, you informed us
that these cracks had been present for several years and had
increased since they were sealed in May 1989. During a recent
visit to the site, we noted the cracking patterns are still present
and appear to have increased since our previous site visit.
The purpose of our geotechnical investigation would be to assess
the subsurface conditions beneath the pavement in order to
determine the cause of distress and to provide recommendations for
mitigation and repair. It shall also include the preparation of
recommendations for the roadway widening including recommendations
for fill materials, compaction requirements, cut and fill slope
stability considerations, pavement design for the added lanes and
recommendations for possible replacement of the existing pavemen%.
Our initial observations and our experience with other projects in
the area suggest that the pavement distress may be caused by
shrinking and swelling of the expansive embankment soils. The
shrinking (from drying) of the expansive embankment soils may be
influenced by the large trees located along the slopes on both
sides of the roadway. Root systems from large trees can remove
significant amounts of moisture from the surrounding soil resulting
in shrinking of the surrounding soils and subsequent depressions

or cracking in the overlying pavement. We have observed the
phenomenon in other parts of the Livermore Valley and are currently
performing investigations on two nearby sites where this phenomenon
has resulted in major distress to pavement areas. It is also
possible that slope failure related to creep or seismic affects may
be at least a contributing cause to the observed distress.
SCOPE OF WORK
The scope of our investigation will follow the outlined tasks
presented in your RFP.
~ask 1
We will perform a reconnaissance of the site and review the
available reports, drawings and maps related to the project.
Task 2
We will perform a field investigation which will include the
drilling a total of five borings within the roadway area. Three of
the borings will be drilled in the area of pavement cracking to
depths ranging from 20 to 35 feet below existing grade. The other
borings will be drilled to depths of 10 feet in the area of
proposed widening. The borings would be drilled under the
supervision of our field engineer who would prepare detailed logs
of the materials encountered and obtain both bulk and relatively
undisturbed samples of the earth materials for laboratory testing.
The bore holes will be backfilled with soil cuttings and capped
with asphalt patch.
Task 3
We will perform laboratory testing on selected soil samples which
will include moisture content and dry unit weight determinations,
Atterberg Limits and shrink-swell tests to evaluate the expansion
potential of the existing fill soils, and static strength test to
evaluate slope stability characteristics of the subsurface
materials. We will also perform R-value tests on the existing
subgrade soils for design of the proposed new roadway section.
Task 4
After we have completed our field and laboratory testing we will
analyze the data and meet with your staff to discuss the findings.
Task 5
We will prepare a written report presenting our findings along with
conclusions and recommendations. Our report will include:
BE~RLOGAR GEOTECHNICAL CONSULTANTS
Page 3
July 24, 1991
Job No. 7992.400
1. A description of the subsurface conditions including the
content and thickness of the existing fill.
2. Our opinions regarding the causes of the existing
pavement distress and recommended mitigation measures.
3. Recommendations for construction of the widened roadway
including: recommended excavation and subgrade
preparation; cut and fill slopes; surface and subsurface
drainage; fill materials; compaction requirements; slope
stability considerations; alternative pavement sections
and possible replacement of the existing pavement; and
necessary precautions for slopes during construction.
4. Design parameters for retaining structures for the new
embankment, if necessary.
5. A general description of geologic hazards including
seismic considerations.
Our work will be performed by our qualified staff of professionals
and technicians under the supervision of Mr. Dan O'Connell,
principal engineer, a registered civil engineer in the State of
California. We will submit ten (10) copies of our final report to
the city of Dublin.
We are prepared to begin our site reconnaissance services
immediately upon authorization. We expect to be able to perform
our field investigation within one to two weeks after
authorization, depending on availability of a subcontracted drill
rig. We expect that our laboratory testing would be completed
within one week after completion of our field investigation and we
would be available to meet with the city to discuss our findings
within two weeks. We would complete our written report within one
week after meeting with your staff.
our firm has provided geotechnical services for the city of Dublin
and other clients on numerous projects in the site vicinity. For
the city of Dublin, we recently provided consultation regarding
pavement distress on Juarez Court and performed a geotechnical
investigation for improvements to Shannon Park. We are on the
project team providing consultation to the city for the West Dublin
Study Area which is located due west of the subject project. We
have also provided consultation to the major property owner in the
East Dublin Planning Area.

REQUEST FOR PROPOSAL (R.F.P.)
GEOTECHNICAL AND SOILS INVESTIGATION
FOR DUBLIN BOULEVARD BETWEEN
HANSEN DRIVE AND APPROXIMATELY
400' WEST OF SILVERGATE DRIVE
The City of Dublin invites Submittals of Proposals to perform and
prepare reports for geotechnic~l and soils investigation for Dublin
Blvd. between Hansen Drive and approximately 400' west of Silvergate
Drive.
Backqround
Currently, Dublin Blvd. west of Silvergate is a two-lane street that
ends in a cul de sac west of Silvergate Drive with few residences and
businesses. Most of the traffic travels between Dublin Blvd. east of
Sitvergate Drive and Silvergate Drive. This pattern will change in
the future due to development west of Silvergate Drive close to Dublin
Blvd. and the extension of Dublin Blvd. further west with interchanges
to the 1-580 freeway. The expected increase in traffic on Dublin
Blvd. makes it necessary to widen Dublin Blvd. and modify its
intersection with Silvergate Drive. Dublin Blvd. is constructed on a
fill embankment between Hansen Drive and Silvergate Drive. Numerous
longitudinal cracks can be seen on this section of Dublin Blvd.
Geotechnical Investigation shall include assessing the subsurface
condition beneath the pavement in order to determine the reason for
the cause of distress and recommending mitigation for it. It shall
also include providing recommendations for fill materials, compaction
requirements, cut and fill slope stability considerations, subgrade
R-value(s), and alternate pavement sections for the added lanes and
possible replacement of the existing pavement.
Scope of Work
The Consultant's work scope shall include the tasks outlined below:
TASK I.
Perform a site reconnaissance and review existing geotech-
nical reports, construction drawings, aerial photographs,
topographic maps, and pertinent documents in order to assess
the conditions prior to construction and the manner in which
the existing two-lane section of Dublin Blvd. (between
Hansen Drive and Silvergate Drive) was constructed.
