sufficient No. of quality control tests both on materials and
workmanship there are chances to occur damages as such they are
requested to watch the performance of the work at closer intervals
and take necessary steps for rectification of such type damages if
occurs duly notifying to the contractor.The field staff have
furnished the extract of QC tests conducted and shortfall tests are
shown in Annexure. Quality control tests have to be conducted as
per the table 900.3,900.4 and 900.6 of MORTH specifications.The Q C
tests done by AEE are inadequate. The DEE & EE had not
furnished Q C test records conducted independently during the
present inspection.As per clause 1.11 of IRC SP - 11 " Quality
Control for construction of roads and runways ", Out of total
tests, preferably 70% to be carried out by AEE/AE, 20% by DEE &
10% by EE.The field officers shall carry out quality control tests
on the materials namely bitumen mineral aggregates used in MSS item
of work to the frequency stipulated in the table 900-4 which is in
MORTH Specification IV revision.The field officers shall carry out
quality control tests on materials used in WMM and satisfy the
requirements specifed in MORT&H. Further the Executive Engineer
has to obtain mix design for GSB and WMM and shall conduct trial
test based on results obtained in trial tests, the mix design shall
accorded then only work shall be started but this is not
followed.Further after completion of the work the field officers
shall conduct necessary quality control tests on finished items of
works and to ascertain the test results obtained is whether within
the acceptance criteria or not as specified in table 903.4.2 which
is as follows.903.4.2Acceptance Criteria : The acceptance criteria
for tests on density and Marshall stability shall be subject to the
condition that the mean value is not less than the specified value
plus :1.65 -1.65(No. of samples) 05The field officers have not
furnished Quality control test records.As per clause 1.11 of IRC
SP-11 Quality Control for construction of roads and runways. Out of
total tests, preferably 70% to be carried out by AEE/AE, 20% by DEE
& 10% by E.E. The test result record register shall be
presented to the QC staff during there inspection. This is not
followed.
