<br />The Consultant will: <br /> <br />1.4.1 Inspect verification of weld ability of reinforcing steel other than ASTM A 706 <br />periodically. <br /> <br />1.4.2 Inspect reinforcing steel resisting flexural and axial forces in intermediate and special <br />moment frames and boundary elements or special reinforced concrete shear walls continuously. <br /> <br />1.4.3 Inspect shear reinforcement continuously. <br /> <br />1.4.4 Inspect other reinforcing steel periodically. <br /> <br />1.4.5 Inspect reinforcing steel prior to concrete placements. <br /> <br />1.5. TASK 4 - CONCRETE <br /> <br />The Consultant will: <br /> <br />1.5.1 Sample and test concrete for quality control to the following standards: <br /> <br />a) Fresh Concrete - ASTM C 172, except modified for slump to comply with ASTM C <br />94. <br />b) Slump - ASTM C 143; one test at point of placement for each compressive strength <br />test, but no less than one test for each concrete load. <br />c) Air Content - ASTM C 231, pressure method; one test for each compressive-strength <br />test. <br />d) Concrete Temperature - ASTM 1064; one test hourly when air temperature is 40 <br />degrees Fahrenheit and below and when 80 degrees Fahrenheit and above, and one <br />test for each set of compressive-strength specimens. <br />e) Compression Test Specimens - ASTM C 31; one set of four standard cylinders for <br />each compressive-strength test, unless otherwise directed. Mold and store cylinders <br />for laboratory-cured test specimens, unless field cured test specimens are required. <br />f) Compressive-Strength Tests - ASTM C 39; one set for each drilled pier, but not more <br />than one set for each truck load. Test one specimen at 7 days, test two specimens at <br />28 days, and retain one specimen in reserve for later testing as required. <br /> <br />1.5.2 Perform continuous inspection of bolts installed in concrete prior to and during placement <br />of concrete where allowable loads have been increased. <br /> <br />1.5.3 Provide periodic verification of required design mix. <br /> <br />1.5.4 Perform continuous inspection of sampling of fresh concrete for: <br /> <br />PSI Conference Center Testing.doc <br /> <br />4 <br /> <br />I <br /> <br />I <br /> <br />I <br />
