TECHNICAL SPECIFICATIONS <br />FOUNDATION PREPARATION <br />a. The CQA MONITOR shall observe and document the foundation preparation including: <br />i. Stripping and excavation activities to ensure that CONTRACTOR places the material <br />in the appropriate stockpile, if stockpiling is necessary <br />ii. Stockpiling activities to verify location of stockpile, material type, and dressing <br />iii. Excavations for moisture seeps, unsuitable foundation soil, elevation, and proper <br />drainage <br />iv. Subgrade preparation to confirm that the surface of the subgrade is free of soft, organic, <br />and otherwise deleterious materials (such as debris, branches, vegetation, mud, ice, or <br />frozen materials); and that soil and rock surfaces that contain joints or fractures are <br />adequately filled in accordance with the SPECIFICATIONS <br />V. Construction of access roads, drainage control features and erosion control features to <br />verify compliance with the DRAWINGS and SPECIFICATIONS. <br />PLACEMENT OF MATERIALS <br />a. During placement of Select Structural Fill, Soil Liner Fill, and Drain Cover Fill the CQA <br />MONITOR shall: <br />Verify the use of appropriate fills <br />ii. Monitor and document material placement; including soil type, particle size, loose lift <br />thickness, moisture conditioning process, compaction equipment and methods used to <br />attain compaction, including number of passes, uniformity of compaction coverage, <br />compacted lift thickness, bonding of lifts, in -place moisture content, and dry density is <br />in compliance with the SPECIFICATIONS <br />iii. Monitor subgrade surface preparation to verify that the surface has been proof - rolled, <br />compacted, or handworked so as to be in a condition suitable for Geosynthetic Clay <br />Liner (GCL) installation as discussed in Section 02200.0 and 02776.2 of the <br />SPECIFICATIONS <br />iv. Monitor and document CONTRACTOR verification of in -place Drain Cover Fill and <br />Soil Liner Fill thickness <br />V. Monitor equipment being used to place Select Structural Fill, Soil Liner Fill, and Drain <br />Cover Fill to verify that the CONTRACTOR places the material in accordance with <br />the SPECIFICATIONS <br />vi. Monitor that Drain Cover Fill is pushed uphill for areas in which the slope exceeds <br />4H:1 V and that the dozer does not perform unacceptable pivot turns <br />vii. Monitor the fill temperature as identified in Section 02200.0 of the SPECIFICATIONS. <br />2.6 DOCUMENTATION <br />A. Documentation kept by the CQA MONITOR shall consist of daily record - keeping, construction <br />problem resolutions, design and SPECIFICATION changes, photographic records of construction, <br />weekly progress reports, chain of custody forms for test sample tracking, and a Construction <br />Certification Report. <br />B. DAILY RECORD KEEPING <br />Daily records kept by the CQA MONITOR shall consist of field notes, observation and testing <br />data sheets, summary of the daily meeting with CONTRACTOR, and reporting of construction <br />problems and resolutions. The CQA MONITOR shall submit this information on a regular basis <br />to MANAGER for review. <br />Earthworks Construction Quality Assurance (CQA) Plan September 24, 2013 <br />01400.1 -5 Revision 1 <br />S\Progects \1550 - CC &V Field Spt CQA PSES Bldg \80 Project Engineering and Design \82 Specificatrons\PSES Pipe Rack Liner Extension SpecificationsVndividual Specification <br />Sections \01400 1 RI Earthworks CQA docx <br />
