This proposal describes our understanding of the project and the scope of services we are being asked to provide. It also includes our unit rate fee schedule and addresses the conditions under which services will be provided. 1\. ��-'C;�f'l� ��I� ��f=��Vl(a�� Based on our understanding of the project, we propose to provide observation and testing services on an As-requested basis during the following phases of construction: o Utility related construction o Lime treated subgrade construction o Concrete construction Utility related services could include but is not limited to: Sampling and laboratory testing of soil and aggregate materials proposed for use during backfilling operations. The laboratory tests would include Atterberg Limits and sieve analysis for sample classification, and Standard Proctor tests to establish the moisture-density relationship for use in evaluating the percent compactions for field density tests. In-place moisture and density measurements by the nuclear method. Lime treated subgrade related services could include but is not limited to: Sampling soil and perform Atterberg Lirnits and lime series to determine percentage of lime required for lime saturation, Terracon Consultanls, Inc 2501 E.

In-place moisture and density measurements by the nuclear method. Concrete related services could include but is not limited to: Field sampling and testing of concrete for slump, air content and temperature Making, transporting, curing and testing cylindrical test specimens Qualified staff will be assigned and scheduled as available to perform the requested service. This can result in changes in personnel assigned to the project. We request a minimum of 24 hours' notice to schedule our services, although we will attempt to meet requests in a shorter time frame. However, we cannot be responsible for additional costs to the project when adequate notice is not given for us to me�t the desired schedule. When our staff is on-site, we ask that the Client's designated representative coordinate with our project manager to confirm when and where observation and testing services are needed. It will not be possible for us to comment on the suitability of materials we have not been directed to observe and test. Whenever possible, our staff will report the results of tests performed in the field to the Client's designated agent before leaving the site. Terracon's innovative and proprietary software application called Construction Materials Engineering and Lab Management System (CMELMS) will be utilized to comprehensively manag� the volumes of data that will be created. Technicians' schedules, costs, and budgets are traciced and daily progress is communicated to keep owners and the design/construction team informed every step of the way. With CMELMS our goals ar� simple. We will deliver: s Written notification of deviations within 24 hours � Field reports in no more than five business days from when field services were provided (typically 1 to 2 days) m Laboratory reports in no more than two business days from when the laboratory services were completed (typically 0 to 1 day) If tests/inspections made indicate non-compliant with the contract documents or referenced specifications, we will promptly notify the on-site contractor personnel so Itelial�le 1:esponsive C;oiivenienY Ir�novative 2 Proposal for Construction Materials Engineerin� Services ` f' �� ;1 t� DOE Construction of Dirks Road Fort Wortt�, Texas l I�� fI II C'�l�,lt-.�1l1 �� July 5, 2016 Terracon Projectl No. 95141041 corrective action can be taken and documented. Failing tests or non-conformance items (deviations) are immediately relayed to the designated parties, and draft reports are available at the end of each day. The test results and inspection information are quic{<ly entered into the system and formal reports are produced. Failing tests and project deviations are easily tracked in a tabular Project Deviation Log which is distributed to all appropriate parties when deviations are reported. The Client will be responsible for providing us a complete set of plans and specifications at the start of the project and providing copies of all subsequent revisions and approved submittals/structural steel shop drawings that relate to our services. �=3. �; �� IVi �� f� �/�i'I (� N Services provided will be billed at the unit rates shown on the attached fee schedule (Exhibit A). Based upon information provided by the City of Fort Worth and Austin Road and Bridge we estimate that the remaining observation and testing services will cost $34,709.00. Our services will originate from our Fort Worth, Texas office location and involve charges for travel time and mileage between the two locations. The quantity of the worl< performed and factors beyond our control, such as weather and the contractor's schedule/efficiency, will affect the actual cost for our services.
