During hot weather, test cylinders shall be covered immediately with dampburlap and cooled or stored otherwise as required to maintain curing conditions consistent withthe curing of the project concrete. Cylinders shall remain in the field until ready fortransportation to the laboratory but not less than 24 hours.

G. Cylinder Tests: Transport the cylinders to the laboratory in a vertical position. Makecompressive strength tests of one cylinder of each set at 7 days and of the other three cylindersof each set at 28 days. If the first two cylinders tested at 28 days show strengths less than 85percent of the specified value, the third cylinder shall not be tested as directed by the ATCConstruction Manager but shall be kept available should additional testing be required. The

testing of each set of three test cylinders at 28 days shall be considered as one strength test.The strength of such test shall be the average of the breaking strengths of the three cylinderscomprising the test except that, if one of the specimens shall show manifest evidence ofimproper sampling, molding, handling, or testing, it shall be discarded and the remaining twoaveraged. If the first two cylinders tested at 28 days show strengths less than 85 percent of thespecified value, the third cylinder shall not be tested at 28 days but shall be kept available forlater testing as directed by the ATC Construction Manager.

H. Reinforcement and Formwork: Inspect reinforcement for surface cleanliness, accessories,clearances, sizes, anchor bolt embedment and height above finish grade and spacing, etc Thismay include but is not limited to rebar cages in caissons, tower anchor bolts, rebar mats on pad& pier foundations, vertical chairs, rock anchors and guy anchor foundations Inspect formworkfor tightness, adequacy, surface quality and cleanliness.

I. Concrete Placement: Inspect methods of discharge, transport timing, placement, consolidation

and finishing.

J. Grout and Grouting: Examine and ascertain that the materials used for grouting conform to theSpecifications. Check grouting operations for conformance with the Specifications and with themanufacturer's recommendations for use. Check that the grout fills all voids and spaces whichare required to be grouted.

K. Grout Compressive Tests: Grout shall be tested for compressive strength. Provide a top platefastened to the top of the mold to confine the mortar and simulate in-place conditions. Nine 2" x2" cubes shall be taken in the field for each set. Three cubes shall be taken on each day thateach strength class of grout is being placed.

3.3 QUALITY CONTROL FOR EARTH WORK

A. Contractor shall provide an independent third party certified inspection and testing agency at theproject. Provide testing for compaction test of soils in place according to ASTM D 1556, ASTM D 2167, ASTM D 2922, and ASTM D 2937, as applicable, and as outlined below.

B. Testing Agency Qualifications: An independent agency, acceptable to authorities having jurisdiction, qualified according to ASTM C 1077 and ASTM E 329 for testing indicated, asdocumented according to ASTM E 548.

C. Tests will be performed at the following locations and frequencies:


28/273



1. Materials:

a. Classification according to ASTM D 2487 of each on-site and borrow soil materialproposed for fill and backfill.

b. Laboratory compaction curve according to ASTM D 1557 for each onsite andborrow soil material proposed for fill and backfill.

2. Footing Subgrade:

a. At footing subgrades, at least one test of each soil stratum will be performed toverify design bearing capacities. Subsequent verification and approval of otherfooting subgrades may be based on a visual comparison of subgrade with testedsubgrade when approved by ATC Construction Manager.

3. Tower & Building Foundations:

a. Conduct at least two (2) compaction tests directly over backfill placed on top of pad& pier style tower foundations. The tests shall be conducted 180° from each otherand at least ten (10) feet apart.

b. For caisson foundations perform one (1) test within 24” of tower foundation.c. Building Slab: Prior to pouring slab, provide at least one test directly under

proposed building.d. Guy Tower: Conduct one (1) compaction test at each guy anchor location

4. Access Road:

a. At each compacted initial and final backfill layer, at least 1 test for each 150 feet ofroad length, but no fewer than 2 tests. Access roads with less than 12” ofcombined initial fill and final backfill Do Not require any compaction tests.

5. Segmental Retaining Wall:

a. Preconstruction Testing Service: Engage a qualified testing agency to perform thefollowing preconstruction testing:

1) Test soil reinforcement and backfill materials for pullout resistance according

to ASTM D 6706.2) Test soil reinforcement and backfill materials for coefficient of friction

according to ASTM D 5321.

b. On walls greater than six feet in height in each compacted backfill layer, performat least 1 field in-place compaction test for each 24 inches of fill depth and each 50feet or less of segmental retaining wall length. Walls less than 6’ in height do notrequire compaction testing.

D. When testing agency reports that subgrades, fills, or backfills have not achieved degree ofcompaction specified, Contractor shall scarify and moisten or aerate, or remove and replace soilto depth required; rec
