INTRODUCTION
TWE understands the importance of this project to the City of Corpus Christi and the special needs associated
with construction of a project of this type. Of particular importance is for the overall project team to be
comprised of experienced professionals working together toward a common objective. This objective is to
obtain a quality project, meeting the intent of the project specifications, as well as completion on schedule
and within budget.
From our Corpus Christi facility located at 826 South Padre Island Drive, we will provide experienced
engineering technicians to perform the on-site testing and inspection services. Additionally, we meet the
requirements of ASTM E-329 "Standard Practice for Inspection and Testing Agencies for Concrete, Steel and
Bituminous Materials Used in Construction" regarding qualifications of the testing laboratory. Additionally,
our Corpus Christi laboratory is accredited in construction materials testing by the American Association for
Laboratory Accreditation(A2LA).
WORK PLAN
TWE's approach to providing materials testing services is to assign qualified engineering technicians, directed
by Senior Professional Engineers, experienced in their respective disciplines. Our assigned Project Manager
will provide communication, service direction, and overall project coordination. It is presumed that the
contractor will be encouraged to provide their own formalized quality control program separate and apart
from our acceptance inspection/testing program stated herein.
We anticipate providing the majority of the required testing services for this particular project on a "part-
time"basis.The anticipated services required on this project are as follows:
A. In-Place Soil Compaction (nuclear method)
B. Cast In-Place Portland Cement Concrete Inspection/Testing
C. Hot Mix Asphalt Concrete Inspection/Testing
All reports of materials tests and inspection services provided will be issued to appropriate members of the
project team. In the event individual reports indicate potential problems or items of non-conformance to the
project specifications,you will be contacted as soon as possible.
SCOPE OF SERVICES
The specific materials monitoring services and laboratory tests anticipated for this project are as follows:
A. In-Place Soil Compaction(Nuclear Method)
• The technician will obtain samples of soil, borrow material and/or base materials and deliver
them to our laboratory facility for testing. Laboratory testing will include Moisture/Density
Relationships,Atterberg Limit determinations and sieve analysis.
• The technician will perform in-place compaction testing (nuclear method) at the frequency
required by the project specifications to determine the moisture content and degree of
compaction.

B. Cast In-Place Portland Cement Concrete Monitoring/Testing
• The technician will sample the concrete in order to perform standard field tests and prepare
test cylinders and/or beams in accordance with project specifications. The frequency of
sampling will also be as directed by the project specifications. Standard field tests include
slump, air content and temperature for normal weight concrete and will also include unit
weight on all samples of lightweight concrete.
• TWE will cure the test specimens and perform compressive strength tests at the age
designated by project specifications.
• The technician will visually estimate the slump of each load of concrete delivered and perform
actual slump tests and other standard field tests when test specimens are prepared, or as
necessary to evaluate concrete consistency.
• The on-site technician will monitor the concrete temperature, ambient temperature, mixing
time, and placement procedures. The technician will also sample concrete at the frequency
specified in the project specifications.
• The technician will record detailed information regarding the location of the placement, date
of the placement,concrete mixture strength requirement and all other pertinent information.
C. Hot Mix Asphalt Concrete Inspection/Testing
• During lay down of hot mix asphalt concrete, the technician will obtain and record
temperature of the mixture and obtain samples for laboratory testing.
• After lay down and compaction, the asphalt will be cored to determine and record in-place
thickness,%air voids, and laboratory density. The in-place%air voids and in-place theoretical
density will be determined from the asphalt cores in the laboratory.
• The asphalt samples obtained during lay down will tested in the laboratory for extraction and
gradation,laboratory density and stability,and maximum theoretical density(rice method).
COST ESTIMATE&GENERAL NOTES
In this section of the proposal you will find our cost estimate. Additional services or tests requested and
not specifically addressed in this proposal will be invoiced per the standard fees set forth in the Master
Services Agreement.
Based on the testing schedule provided in the project construction documents (plans) provided to us at
this time and the anticipated construction schedule, we have established what we believe is the most
realistic cost estimates for this project. Please remember that the units stated are only an estimate. Due
to factors beyond our control such as weather, unforeseen conditions, contractor expertise, contractor
scheduling, etc.,the cost of our services may vary from the estimated amount.
We estimate the cost of the construction materials testing for our proposed Scope of Services will be
$85,490.00 as detailed in the following section, although all services will be invoiced on a time and
materials basis.
A minimum 4-hour labor equivalent charge is applicable for all field testing and inspection services.
Overtime rates for field personnel are applicable for all hours worked in excess of 8 hours per day,
weekends, and holidays and are assessed at 1.5 times the standard rates. All field hours will be charged
portal to portal from our Corpus Christi laboratory. All sample pick-ups will be charged travel time from

portal to portal and will include associated vehicle charges.Administrative costs, Engineering consultation
and evaluation in connection with field and laboratory testing services will be charged at a rate of
approximately one hour for each 20 hours of field work performed.
Our prices include copies of our reports distributed through e-mail in accordance with your instructions.
Additional copies mailed at $0.50 per page. Direct expenses incurred in connection with the project will
be invoiced at cost plus 15%for handling. Travel and lodging expenses for out of town assignments will
be invoiced at cost plus 15% or $125.00 per day, whichever is greater. Our terms are net 30 days upon
receipt of invoice. Invoices will be submitted on a monthly basis.
