The structural framing will be comprised of: Steel columns, beams, joists and/or trusses - Metal deck and roof - Structural masonry walls - Reinforced concrete - Precast structural concrete Also included as part of the construction will be Underground utilities - Asphalt drives and parking lots Site grading fill placement - Cast in -place concrete retaining walls 2.0 SCOPE OF SERVICES 2.1 Field and Laboratory Services Terracon will provide appropriately trained employees equipped to respond to the materials testing and construction observation needs of this project as scheduled by the Client or your designated representative. Based on our review of the information provided above, we understand the scope of the on -call services includes: Earthwork observation and testing: Site preparation - Site grading fill placement - Foundation wall backfill - Utility trench backfill Floor slab and pavement subgrade preparation Laboratory soil/aggregate testing - Standard Proctors - Atterberg Limits - Aggregate gradations Shallow foundation bearing soil observation and testing Responsive Resourceful Reliable 2 Proposal for Construction Observation & Materials Testing Services Waterloo Treatment Plant Biosolids Modifications Waterloo, Iowa April 30, 2020 = Terracon Proposal No. P13201008R lrerracon - Foundation soil conditions will be compared to information contained in the geotechnical report for this project to determine if suitable bearing conditions exist If authorizes, structural steel observation of field -made connections - Review welder certifications - Perform periodic visual observations of structural welded connections including primary framing members • Observations of ancillary framing such as for rooftop units, curtain walls, brick ledges and cold -formed light gauge steel framing is not a part of this scope. - Visual observation of bolted connections • We assume bolted connections will either be snug -tight or tension control bolts will be utilized if full pre -tensioning is required. Observations of other methods of pre - tensioning can be performed, but may require additional time and cost. Structural masonry testing - Material sampling • Measure grout flow/slump and temperature and cast 3" x 6" grout prisms. For estimating purposes, we assume that cardboard grout sample boxes will be allowed due to the low cost and convenience. However, they are not recognized as an approved mold by ASTM. If the client wishes grout prisms to be formed in general accordance with ASTM C1019, we will need access to forming materials and a protected space onsite to make the samples, and additional costs will apply. • Sample mortar and cast 2" x 4" cylinders. - Laboratory testing • Compressive strength of grout It should be noted, Helical Pier observation has not been requested for this project but can be provided upon request at additional cost. Project Management - Attendance at pre -construction and project meetings at Client's request Technical consulting at Client's request Supervision of laboratory and field services - Preparation and review of project reports and invoices If we have misunderstood any aspect of the proposed project, please advise us at once so we can evaluate the scope of services and make any necessary adjustments prior to finalizing the contract. Once the project is underway, you can request additional services. We will confirm your request by sending you a short supplemental agreement form that states the additional services, making them part of the original agreement Responsive Resourceful Reliable 3 Proposal for Construction Observation & Materials Testing Services Waterloo Treatment Plant Biosolids Modifications Waterloo, Iowa April 30, 2020 Terracon Proposal No. P13201008R 2.2 Scheduling 1 rerracon Terracon's services will be performed on an as -requested basis with scheduling by the Client or the client's designated representative. Terracon will not be responsible for scheduling our services and will not be responsible for tests or observations that are not performed due to failure to schedule our services on the project. Since our personnel will not be at the site on a resident basis, it will be imperative that we be advised when work is in progress. Services should be scheduled a minimum of 24 hours in advance. Scheduling personnel will be on an as -available basis which may require changes in personnel assigned to the project. For instances of short - notice requests, personnel may have to be utilized which have a higher rate than those normally assigned and this higher cost may be passed on to the client. All requests for services should be submitted to the Cedar Falls, Iowa office at the following phone number: (319) 277-4016. Services should not be scheduled through our field personnel. We recommend the scope of work described in this proposal be provided to the person(s) responsible for scheduling our services so they are aware of the services that are proposed. 2.3 Data Collection and Reporting All field technicians are responsible to provide a daily report identifying what work was found to be in compliance with the project specifications and drawings and report any non -conformances. The field technicians are required to immediately communicate any non -conformances to the site superintendent and our Project Manager. Effective and timely communication is essential for non -conforming items. Our Project Manager will be responsible for reviewing each technician's reports, keeping non-conformance lists up-to-date, and communicating test results in a timely manner. To ensure our project manager and field personnel meet the goals we have set for report turnaround, we have developed report tracking software to evaluate the status of any test result or report within our system. This allows us to achieve better communication, more consistency, and faster turnaround of reporting on the project. Data, observations, and other testing and inspection information are easily entered into the system and reports are auto -generated allowing for immediate availability of test results. Terracon will maintain non-conformance logs and lists for all testing types performed by us. The list will be maintained electronically in our database and can be updated and e-mailed or printed at any time.

The acronym stands for Construction Materials Engineering Laboratory Management System and is utilized by construction materials engineering and testing operations in our offices. CMELMS is a complete and comprehensive field and laboratory testing data and results management system. The application can manage an unlimited number of reports and data for ease of reporting and documentation purposes. Features in the application include accessing and distributing test results and field observation reports by a push of a button. CMELMS automates the delivery of our testing and inspection information and can be used anywhere with an Internet connection or through a wireless device. Data (test results and inspections) can be entered into the application right from the project site so that project managers and engineering staff have real-time access to the field data. Final Client Reports are produced in the same application, which allows us to achieve better communication, more consistency, and faster turnaround of reports on the project. 2.3.2 Report Turnaround Time Our Project Managers and/or field technicians will report failing tests or non-conformance items immediately to the designated parties and will typically have digitally -signed reports distributed by the end of the next business day. As stated, using our CMELMS software and our field reporting and communication services and capabilities, the test results and inspection information is quickly entered into the system and a report produced, Non -deviation reports will typically be digitally signed and distributed within 5 business days of service. Laboratory test reports will typically be digitally signed and distributed within 2 business days of the completion of each test. Our reports can be sent digitally via email, posted to our Client Document Website (CDW), or posted to a designated ftp website. 2.4 Terracon's Incident and Injury -Free Culture Employee safety is a core value of Terracon and we are committed to an Incident and Injury -Free (IIF) workplace. It is our personal and organizational commitment at all levels of the company to everyone going home safe to their family every day. All employees are expected to perform their job assignments with safety as a primary objective. Terracon dedicates the time, resources, and equipment necessary for an IIF environment and no employee will be required to work in unsafe conditions. Site Access and Safety.

These rates will apply for the duration of the project. Based on our review of the above -referenced information, our estimated cost to perform the proposed scope of services is $20,189.00. A breakdown of our cost is provided in the attached Cost Estimate. For the purposes of developing this estimate, the quantities were estimated based on typical means and methods utilized by contractors/subcontractors in this area. It should be noted the Client would be billed only for the amount of service provided, i.e. Terracon will not bill for the total budget if the total booked is less than the budget. Please note this is only a budget estimate and not a not -to -exceed price. Many factors, including those out of our control, such as weather and the contractor's schedule, responses to requests for information, and how often we are called to the site, will dictate the final fee for our services. Furthermore, all costs associated with deviations, re -testing and re -inspections of failing items, on -site standby time, overtime, and short notice premiums are not included in our estimated cost.
