Statement of Qualifications for Construction Material Testing Services Irerracon Central Efland/Northern Buckhorn Sewer Extension in Orange County,NC y September 21,2011 a Terracon Proposal No.P70110416 PROJECT MANAGEMENT APPROACH Signify Presence and Responsibilities at the job site. If required by the building official, Terracon personnel will sign in on the appropriate form posted with the building permit. Observe Assigned Work. Terracon personnel will inspect work for which they are responsible and aware of for conformance with the building department approved (stamped) plans and specifications and applicable provisions of the applicable North Carolina Building Code. Our testing and observation services will be scheduled by the Owner's or Contractor's representative and performed on a part-time, as-requested basis. This scheduling practice in itself will result in lower fees as compared to a full-time site technician. We propose to utilize the listed procedures during testing and observation of the following elements to ensure a high standard of quality control and efficiency: • Soils — The Terracon technician will perform soil density testing using nuclear density gauges. This will reduce site visit durations and result in lower fees. • Foundations & Cast-in-Place Concrete — The same Terracon technician performing foundation testing can also inspect the reinforcing steel and test the concrete, eliminating the need for multiple technician site visits. • Hot Mix Asphalt Paving —The Terracon technician will utilize a nuclear density gauge to test the compaction of in-place hot mix asphalt at the time of placement, eliminating the need for a follow-up coring visit. Fees for mileage and equipment (trip charges)will be included in the hourly personnel rates. Provide Qualified Personnel. Terracon will provide qualified personnel to perform the assigned work. Our proposed staff has the appropriate certifications including: [CC (International Code Council), NICET (National Institute for Certification of Engineering Technologies), ACI (American Concrete Institute), PTI (Post Tension Institute), NCDOT (North Carolina Department of Transportation). Report Nonconforming Items. Terracon personnel will bring nonconforming items to the immediate attention of the contractor. If any such item is not resolved in a timely manner or is about to be incorporated into the work, the design team, the owner and the building official will be notified immediately and the item noted in Terracon's written report. Terracon personnel will write a separate report to be posted at the job site, if requested, regarding noted discrepancies. The report will contain, as a minimum, the following information about each nonconforming item: • Description and exact location • Reference to applicable detail of approved plans/specification • Name and title of each individual notified and method of notification • Resolution or corrective action taken. In addition to communicating non-conformance issues immediately to the designated parties, any non-conformance item that cannot be corrected the same day will be recorded in a non- 10
