TWE Proposal No.P18-0034
Mr.Vargas:
Tolunay-Wong Engineers (TWE) appreciates the opportunity to submit our proposal to provide construction
materials testing and inspection services for the above referenced project. The proposed scope of services was
based on the testing schedule and the project plans downloaded from the CivCast website.
The cost estimate contained herein was developed using the scope of services from the drawings and specification
and the unit rates presented in the Master Service Agreement (Project No. 17101A) between the City of Corpus
Christi and Tolunay-Wong Engineers, Inc. We understand that the City will issue a Project Task Order upon
acceptance of this proposal in accordance with the MSA and the Task order will serve as our authorization to
proceed with our services for the project.
Tolunay-Wong Engineers has established a reputation for excellence in the materials engineering field through a
business philosophy based on quality professional services responsive to the needs of our clients. We thank you
for the opportunity to serve you with this philosophy and your consideration for this project. Please do not
hesitate to contact us,if you have any questions regarding the proposal or if additional information is needed.
Respectfully submitted,
Tolunay-Wong Engineers,Inc.

INTRODUCTION
TWE understands the importance of this project to you 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
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. Additional laboratory testing
to be performed on crushed limestone base (Type A/Grade 1) material provided will include
L.A.Abrasion and laboratory-soaked California Bearing Ratio(CBR).
• 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 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.
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 Master Service Agreement(Project No.
17101A) between the City of Corpus Christi and Tolunay-Wong Engineers,Inc.
Based on the testing schedule, the project bid documents (plans/Specifications) provided to us at this
time,and the anticipated construction schedule,we have established what we believe is the most realistic
cost estimate 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 (Base Bid)
will be$15,350.00 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.

website.
2. Soil sample pick-up charges will not be assessed if retrieval of soil sample(s)occurs during performance of
other scheduled testing at the site.
3. Concrete sample pick-up charges will not be assessed if retrieval of concrete test specimens occurs during
performance of other scheduled testing at the site.
4. Concrete compressive strength samples taken will consist of five (5) 4"x8" cylinders to be tested as
follows:one(1)at 7 day's compressive strength,three(3)at 28 day's compressive strength,and one(1)to
