Re: Construction Materials Testing Services For: E17058 Street Preventative Maintenance Program FY2018 for Overlays Corpus Christi,Texas TWE Proposal No.P18-C117 Ms.Alaniz: 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 project plans for a similar FY2017 project downloaded from the CivCast website,as requested. The unit rates contained herein will cover the scope of services from the drawings and specification and are based on the TWE 2018 Schedule of Fees. 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.

Proposal No.P18-C117 Page 2 of 4 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 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, base materials, and/or cement stabilized base and/or subgrade materials and deliver them to our laboratory facility for testing. Laboratory testing will include Moisture/Density Relationships (ASTM D698), Moisture/Density Relationships (ASTM D 1557), 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.P18-C117 Page 3 of 4 B. Cast In-Place 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. 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 maximum theoretical density(rice method). COST ESTIMATE & GENERAL NOTES In this section of the proposal you will find the 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 and the 2018 Schedule of Fees which is attached for your use. At this time,the cost estimate of the construction materials testing for our proposed Scope of Services is estimated to be$150,000.00. Services provided 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.
