• 3.11 Compaction and Testing <br />The Owner, through the Engineer, shall perform soil compaction, soil classification, <br />soil permeability, shear and cohesion, gradation determinations and other tests he <br />deems necessary for the proper control of construction. The Contractor shall <br />perform, or pay the cost of performance, all tests which are required to be run as a <br />result of a failure of his original construction or work. In addition, the Contractor <br />shall provide at his own expense the following tests: <br />A. Concrete Tests: See Section 03300 -Cast-in-Place Concrete. <br />B. All performance tests such as pipe line pressure tests for leakage, operation <br />of gates and other mechanical devices through design limits. <br />C. Retesting of all performance tests including both those originally paid for by <br />the Owner or the Contractor, all at his own expense. <br />D. Prior to the onset of construction the on-site borrow areas, areas of exca- <br />vation, off-site borrow pits or quarries, and stockpile areas shall be tested to <br />determine gradations, optimum moisture content, Standard Proctor Density <br />(ASM D698, AASHTO T-99), and the Atterberg Limits. After these tests <br />have been submitted to the Engineer, the Engineer will give written approval <br />or rejection of the materials. <br />~• E. Density tests performed on compacted soils to determine compliance with <br />these specifications shall be performed at the direction and expense of the <br />Owner. Nuclear Density Tests will be acceptable for homogeneous fill areas <br />if at least one Sand Cone Density Test is performed for every ten Nuclear <br />Density Tests. The Sand Cone Density Test must be taken adjacent to the <br />preceding Nuclear Density Test. <br />Classifications and compaction curves to be used with the Nuclear Density <br />Test shall be taken and submitted prior to construction. The classification <br />will also include a description of soil properties, including color, as well as <br />the information required under Part D of this section. <br />Copies of all tests performed by the Contractor shall be sent to the ARCO Project <br />Engineer. <br /> <br />02200-12 <br />
