Calallen Drive (Red Bird Lane to Burning Tree Lane)
City Project# 18009A
2018/2019 MSA Geotechnical and Materials Testing (17099A)
TO Number: #24-17099Y
Corpus Christi, Texas
Proposal #: 273539
Dear Ms. Alaniz:
Professional Service Industries, Inc. (PSI), an Intertek company, is pleased to submit this proposal
to conduct a geotechnical exploration at the above referenced property. PSI thanks you for the
opportunity to propose these geotechnical services and looks forward to being part of the design
team. This work involves reconstruction of Calallen Drive from Red Bird Lane to Burning Tree
Lane (approximately 1610 lineal feet) in Corpus Christi, Texas. A review of project information,
along with a proposed scope of services, schedule and fee information is provided below.
Project Understanding
Project information was provided by Ms. Marisa Alaniz, EIT with the City of Corpus Christi: The
geotechnical exploration will be performed for street design per City of Corpus Christi
requirements.
PSI understands that it is desired for this street to be a 30-year pavement design for both HMAC
(with multiple options) and concrete street and sidewalk including subgrade compaction
requirements. PSI also understand that the City of Corpus Christi will provide design traffic
information that we will utilize to determine appropriate design traffic ESALs and resulting
potential pavement section options. The design will include an option consisting of a flexible
pavement section having a thickness of 7.5 inches. We will evaluate the potential of recycling the
existing pavement materials into the new pavement section options.
As requested, PSI will initially submit an unsealed draft report for City and Consultant to review
along with a preliminary invoice.
Should the above information or assumptions be inconsistent with planned construction, the Client
should contact the PSI office and allow necessary modifications to be made to the proposal.

Corpus Christi, Texas April 24, 2019
SCOPE OF SERVICES
The geotechnical engineering scope of services will include the following items.
• Field exploration consisting of drilling and sampling of the subsurface materials and
observing groundwater levels at the site.
• Laboratory testing of the subsurface materials.
• Performing engineering analyses and providing geotechnical recommendations in a
geotechnical report.
Field Exploration
PSI proposes a total of 6 exploratory borings for this project. Three (3) of the borings will be drilled
to a depth of 5 feet for pavement design and 3 borings will be drilled to the 25-foot depth for
pavement, utility and signal design purposes. The table below summarizes the planned exploratory
boring program.
Summary of Borings
Design Element Number Boring Depth(s) Drilling Footage
of (feet) (feet)
Borings
Pavement Design 3 5 15
Utilities and Signals 3 25 75
TOTAL 6 --- 90
The borings locations will be identified in the field using GPS coordinates using a hand-held GPS
device. Approximate GPS coordinates for the boring locations will be obtained from the Google Earth
computer program. Surveying of the boring locations to obtain surface coordinates and elevations is
beyond the scope of work and should be surveyed by others prior to construction.
References to elevations of various subsurface strata will be based on depths below existing grade
at the time of drilling.
• During the field activities, the subsurface conditions will be observed, logged, and visually
classified field notes were maintained to summarize soil types and descriptions, water
levels, changes in subsurface conditions, and drilling conditions
• Final depths of the borings may be extended or reduced depending on the subsurface
materials identified during field activities.
• PSI will contact Texas One Call/Dig Tess, etc. or other public utility clearance companies
prior to the start of drilling activities. It is our experience that these companies do not mark
the locations of privately owned utilities. This proposal is based on private utility lines and
other subsurface appurtenances are located in the field by others prior to field activities.
• Some damage to the ground surface may result from the drilling operations near the work
areas and along ingress/egress pathways. The field crew will attempt to limit such
damage, but no restoration other than backfilling the borings is included in this proposal.
Excess auger cuttings and drilling spoils will be collected and disposed of offsite.
• PSI will exercise reasonable caution to avoid damages to underground utilities by
contacting local utility companies prior to the field activities. However, private utility
locations are often unknown by public utility companies and by the utility owners.
Therefore, PSI will not be responsible for damage to the site or any buried utilities that are

Laboratory Testing
Representative soil samples obtained during the field exploration program will be transported to the
PSI laboratory for testing. The nature and extent of this laboratory testing program will be dependent
upon the subsurface conditions identified during the field exploration program. The laboratory testing
program on selected samples will include moisture content tests, Atterberg limits tests, sieve
analyses and other tests as required to identify the engineering characteristics of the subsurface
materials.
Engineering Analyses and Report
The results of the field exploration and laboratory testing will be used in the engineering analysis
and in the formulation of the recommendations. The results of the subsurface exploration,
including the recommendations and the data on which they are based, will be presented in a
written geotechnical report. The geotechnical report includes the following items:
➢ Boring Location Plan (Map of Boring Locations)
➢ Existing soil characteristics along route.
➢ Water table depth along route.
➢ Fill material recommendations with and without existing road bed.
➢ Recommendations and considerations for fill and compaction methods in high
water table areas, and in poor underlying soil areas, if any.
➢ Recommendations on how to mitigate roadway settlement, if any, due to fill
overburden, loads during construction, and operational loads after completion.
➢ Trench excavation design parameters
➢ OSHA soil type classification

➢ Traffic counts
➢ % growth over pavement life
➢ Design vehicles
➢ Design trucks
➢ Roadway pavement and shoulder design section recommendations will be
provided to include soil amendment alternatives, geogrid and geotextiles
alternatives, flexible pavement, and rigid pavement. Section recommendations
based on average vehicle trips per day and projected traffic growth for 30 years
to be provided by the City, with an appropriate ESAL calculated from the
provided traffic count data. Multiple feasible pavement options will be included. A
min. 2.5 Serviceability Terminal Index will be utilized. No bond breaker will be
utilized for asphalt pavements
➢ Discussion of utilizing a TX-5 geogrid as an acceptable alternative to lime
stabilization
➢ Narrative of benefits/risks of proposed components
➢ Recommendation for prolonging pavement life and protecting the pavement
section during construction will be included
➢ If proposed flexible pavement section exceeds 7.5 inches of HMAC, 1 equivalent
pavement section shall include 7.5 inches HMAC.
➢ For thick pavement sections, alternative section reduction options will be
included such as multiple grid option, increased asphalt thickness,etc.
➢ Construction testing recommendations.
Interaction with the City PM will be made and a draft report for review will be submitted prior to
report finalization. An alternative to providing multiple pavement options for each set of material
components would be to discuss recommended sections with the City and AE for review and
approval to determine desired options to be included in the report.
A pdf version of the geotechnical report will be prepared and submitted by email to the Client and
design team. If requested by the Client, additional hard copies can be provided. The geotechnical
report will be reviewed, signed, and sealed by a registered Professional Engineer.
SCHEDULE
Based on the site being accessible to the truck rig, drilling can commence within approximately
one week after receipt of authorization to proceed, weather permitting. Preliminary verbal
recommendations could be made available after laboratory testing is completed. A final report
can be provided within 5 weeks of authorization.
Delays sometime occur due to adverse weather, utility clearance requirements, site clearing
requirements for drill rig access, obtaining drilling permits, obtaining Right of Entries and other
factors outside of PSI's control. In this event, PSI will communicate the nature of the delay and
provide a revised schedule at the earliest possible date.
