(c) Continuous inspection is defined as the continuous presence of the Inspector to observe one construction operation and/or perform tests and take measurements at critical points in the operation to determine and document that the work being performed complies with the specifications and to be immediately available for consultation in case of emergency or changes in work conditions.

(8) The Contractor's inspection system shall include the following items of work that will require the Contractor's quality control. Any item of work not listed below shall be performed or constructed as shown on the drawings and as specified in the construction and material specifications.

(a) The Contractor's inspection on all items not listed in (b) through (f) below shall consist of periodic review of those items to assure that all contract specifications are being met and that the items are being properly installed or carried out.

(b) Seeding, Sprigging, and Mulching - Quality control shall consist of determining that the vegetative materials supplied comply with the specifications; that the areas to be vegetated are properly prepared, smoothed and graded; and that sprigging is performed as specified. Full time inspection shall be required.

(c) Excavation - Quality control shall consist of full time inspection to determine that all excavation is being accomplished as specified and that the specified excavation has removed all required or unsuitable materials and that grades are properly documented. The Inspector shall determine that all materials selected for use in backfill of the specified works are free of undesirable materials and that all materials are placed in the designated waste, stockpile or fill areas.

(d) Lime-Treated Earthfill - Quality control shall consist of full time inspection of lime-treated earthfill placement. The Inspector shall select materials from the required excavations, stockpiles and/or borrow area(s) to insure the completed lime treated earthfills are constructed in accordance with the drawings and specifications.

The Inspector shall select and obtain representative samples of the materials and have moisture-density curves made (according to ASTM D-698 test procedures) of each Unified Soil Classification material to be placed in the specified earthfills. Moisture density curves shall be completed as necessary to provide data needed when lime-treated earthfill operations begin. A “One-Point Family of Curves Method” (hereafter referred to as the one point method) shall be employed to determine the optimum moisture and maximum density values for the lime-treated earthfill materials. A “One-Point Family of Curves Method” (hereafter referred to as the one point method) shall be employed to determine the optimum moisture and maximum density values for all lime-treated earthfill materials. The procedure for performing the one-point method is as follows:

94-6

(1) construct a family of curves using compaction test data compiled on soil samples tested in accordance with the procedure set forth in ASTM D-698, (2) make a one-point compaction test specimen from soil material representing the lime-treated earthfill material that is being placed, (3) plot the one-point moisture-density values, obtained from the test, on the family of curves, (4) using the curves above and below the plotted point as a guide, draw a new compaction curve through the plotted point, (5) use this curve as the control for the moisture and density of the material being placed. Unless otherwise approved by the Engineer, at least one one-point test shall be conducted for every three in-place moisture density tests that are taken.

More frequent tests shall be required if compaction requirements are not being obtained; if compaction requirements are not being met or if lime-treated earthfills are being placed in critical areas such as conduit and concrete backfills. In these instances, continuous inspection shall be required during all lime-treated earthfill placement to determine that foundation conditions are satisfactory; that the lime is properly incorporated into the earthfill materials and are free of undesirable materials; that proper compaction and moisture requirements are being maintained; and that hand and mechanical compaction are being accomplished as specified.

(e) Furnishing and Handling Lime, Quicklime - Quality control shall consist of continuous inspection during handling and processing the quicklime.

The Inspector shall assure that the proper amount and type of quicklime is delivered to the site. The Inspector shall ensure precautions are taken to protect workers from dangers associated with handling quicklime and to ensure the lime remains dry until applied and incorporated into the soil being treated. The Inspector shall ensure the specified amount of quicklime is uniformly applied to and incorporated into the proper volume of soil before processing. The Inspector shall also assure that the specified percentage of lime is mixed with the soil thoroughly. The Inspector shall select a representative sample of the soil lime mixture of not less than five pounds for submittal to a qualified geotechnical lab for Atterberg Limits and pH testing. If the Atterberg Limits test results in a Plasticity Index of 20 or less or the pH is 12.4 or more, no adjustment of the application rate of quicklime will be required. If nether of those criteria are met, the amount of quicklime shall be increased 1% upon approval of the Project Engineer and the soil lime mixture re-tested.

This sequence of testing and increases will continue until either one of the criteria have been met or the percentage change in the results have become insignificant. The final rate used shall be the application rate for the project.

(f) Site preparation – Quality control shall consist of full time inspection of all earthfill required under the bid item for Site Preparation. The Inspector shall select materials from the required excavations, stockpiles, and/or borrow area(s) to insure the completed earthfills and topsoil geometries and thicknesses are constructed in accordance with the drawings and specifications. The Inspector shall route the various materials to the proper zones and determine suitability of each type of

94-7 material for a particular zone. Quality control tests for moisture and density shall be required.

The Inspector shall select and obtain representative samples of the materials and have moisture-density curves made (according to ASTM D-698 test procedures) of each Unified Soil Classification material to be placed in the specified earthfills. Moisture density curves shall be completed as necessary to provide data needed when earthfill operations begin. A “One-Point Family of Curves Method” (hereafter referred to as

94-8 the one point method) shall be employed to determine the optimum moisture and maximum density values for all earthfill materials. A “One-Point Family of Curves Method” (hereafter referred to as the one point method) shall be employed to determine the optimum moisture and maximum density values for all earthfill materials. The procedure for performing the one-point method is as follows: (1) construct a family of curves using compaction test data compiled on soil samples tested in accordance with the procedure set forth in ASTM D-698, (2) make a one-point compaction test specimen from soil material representing the earthfill material that is being placed, (3) plot the one-point moisture-density values, obtained from the test, on the family of curves, (4) using the curves above and below the plotted point as a guide, draw a new compaction curve through the plotted point, (5) use this curve as the control for the moisture and density of the material being placed. Unless otherwise approved by the Engineer, at least one one-point test shall be conducted for every three in-place moisture density tests that are taken.

More frequent tests shall be required if compaction requirements are not being obtained; if compaction requirements are not being met or if earthfills are being placed in critical areas such as conduit and concrete backfills. In these instances, continuous inspection shall be required during all earthfill placement to determine that foundation conditions are satisfactory; that the earthfill materials are of the type selected for placement and are free of undesirable materials; that proper compaction and moisture requirements are being maintained; and that hand and mechanical compaction are being accomplished as specified.

(9) The skills, knowledge, abilities and experience needed by the Contractor's quality control personnel to perform the quality control shall be as follows:
