Proposal No.P19-C104 Page 2 of 5 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. Further, 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.

Proposal No.P19-C104 Page 3 of 5 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 samples for laboratory testing and,as requested,obtain and record temperature of the mixture. • 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 for the requested scope of services. 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 document 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 the requested Scope of Services will be $43,600.00, as detailed in the following section, although all services will be invoiced on a time and materials basis.
