1. Details of categories of check codes A, B & C including accepting and deviation
dispositioning authorities are indicated at annexure-I
2. GETCO specification shall mean GETCO technical specification, approved
drawings data sheets and Law provisions applicable for the specific contract.
3. Acceptance criteria and permissible limits shall be as per relevant Indian
Standards and/ or prevalent code of practice / GETCO specifications.
4. It is clarified that the tests indicated at column 2 of this FQP i.e. Against column
“component operation & Description of test “, are only generally required to be
conducted. However, GETCO reserves the right to carry-out any additional tests
at any stage if the situation so warrants.
5. SE (TR) of circle shall approve testing laboratory before accepting the test results
6. SE (TR) of circle shall approve the sources for cement, coarse aggregate, fine
aggregate & water before actual utilization.
7. All the testing & measuring equipments used by the contractor for testing are
required to be calibrated. A Copy of valid calibration report shall be retained by
GETCO based on the joint inspection.
8. Classification of foundations shall be approved by GETCO based on the joint
inspection report & Soil investigation reports.
9. Zone-IV fine aggregate shall be used for nominal mix. Reinforced cement
concreting work.
Zone-IV fine aggregate shall be avoided for design mix reinforced cement
concreting work unless tests have been done to ascertain the suitability of
proposed with the prior approval GETCO sit.
10. Bricks should be free from cracks, flaws and modules of free lime. They should
have smooth rectangular faces with sharp corners and should be uniform in
In case of cement is in the scope of the contractor, the same shall be procured
from sources approved by GETCO site and got tested on sample basis for
specified acceptance tests as specified in the FQP at a reputed third party lab
approved by GETCO site.
The samples of cement for site testing shall be taken within three week of the
delivery and all the tests shall be commenced within one week of sampling. If the
cement remains in store for a period of more than Six months. All the site tests
are required to repeated before usage.
The source and grade of cement shall be as per approved design mix.

Nigam or the rerollers approved by main producers.
The results of testing of cement and reinforcement steel referred in 12.1 and
above shall be got approved from GETCO site before cement and reinforcement
steel are put to use. However, in exceptional cases due to exigencies of work,
GETCO site may authorize the contractor to use cement and reinforcement
steel even before the test results are received. However, in all such cases, if
the test results subsequently received are found to be not complying with the
specified acceptance criteria, the contractor shall have to dismantle and recast
all such foundations cast with such non-conforming materials at his own cost.
Confirmation to this effect shall be obtained from the contractor by the project
authorities beforehand in all such cases.

execution of contract
will neither relieve the contractor from his contractual obligations and
responsibilities, nor does it limit the owner’s right under the contract.
15. In case, requirement of special items like super sulphate cement, corrosive
resistant reinforcement
Steel (CRS) etc. arise due to site conditions, the specific approval of GETCO may
be obtained before using the same and all the tests as per relevant standards
shall be carried out.
16. All the materials shall be stored by the contractor in a manner affording
convenient access for identification and inspection at all the times. Storage of
material shall be in accordance with IS: 4032 (latest edition).
