Task 004—Pavements and Bases Summit will provide a senior engineering technician working under the supervision of a registered engineer to observe proofrolls of the prepared soil subgrade prior to ABC stone, asphalt and concrete paving operations.ABC stone base compaction tests will also be performed by the nuclear gauge method or sand-cone method, as related to a standard proctor laboratory compaction test. We will provide a Senior Engineering Technician as needed to observe the placement of concrete pavements and hot-mix asphalt. Additionally, we will periodically monitor hot-mix asphalt delivery temperatures, rolled thickness, and perform asphalt density testing with a nuclear gauge. Task 005—Laboratory Testing In an effort to maintain the highest quality control standards within our company, our laboratory, equipment, and personnel are inspected both by our internal Quality Control Group and a variety of external agencies. Our laboratory and personnel periodically go through inspections and have received accreditations through CCRL (Cement and Concrete Reference Laboratory) relating to ASTM C1077 Standards; and /\MP5. (AASHTO Materials Reference Laboratory) relating to AASHTO and ykBIM [) 3740 Standards. Each of these organizations is part of the National Institute of Standards and Technology. We have also been inspected and accredited by the Soil and Materials Laboratory of NCDOT. Laboratory testing will be performed in accordance with the pr ject document requirements to evaluate that materials comply with project requirements. Results of laboratory testing will be provided to the construction manager and designated pr ject team members as soon as practicably available. We anticipate that testing will be required for backfill material. Samples collected from the job site will be secured and returned to our laboratory for testing, as required. Our budget includes laboratory testing of soils, including maximum dry unit weight/optimum moisture curves, Atterberg limits, and No. 200 wash sieves for 2 samples. Task 006—Pr ject Management and Engineering Consultation Our p ject organization will include various field testing and inspections staff working under the direct supervision of Jeff Elliott, PE. Our assigned project ject manager will oversee the administrative functions for the project, including assignment of appropriate field personnel, review of field data, laboratory data, inspection reports, and communication the following with pr ject team personnel and owner: • The results of our field testing and inspections for each day will be summarized in a daily field report, with all results communicated to appropriate on site personnel. 3
