LABORATORY TEST EQUIPMENT REQUIRED FOR CIVIL WORK AT THERMAL POWER SITES.

Till date we have discussed about the specific packages of civil work like MAIN Power House , CHP , AHP , Water System including NDCT ,CW etc. These packages are having high percentage of civil work than others in Thermal Power Station. We have left out following works which are comparatively less in volume and easy to execute. Those packages are Roads , drains ,culverts , Security Gate and watch Tower, enabling works ( The facilities to be created before actual execution of the project) , Quarters for staff and workers of the owners , other social obligation like School , Hospital , First Aid Centre etc. Different Small pump House , Transformer foundations , Storm water drainage system. All the above packages are permanent in nature and required at the Power Station Location at different times . One major job we have not discussed levelling and filling  of the land  .We have excluded Rail way lines , Merry Go Round System , sidings etc as those packages are executed by construction wing of Railway .

A common requirement of all projects are Quality System of the civil work . There are two distinct part . One is MQP ( Manufacturing Quality Plan) and other is FQP ( Field Quality Plan). Both the plan identifies the process points where checks to be done and if required the same will be recorded in a pre-determined protocol sheet. It also identifies the customer hold points at different stages . Construction people who are working in field needs FQP before start of their work. MQP will not be our part of discussion.

To start civil work at site we need to establish a civil laboratory to conduct routine test on different works . The following instruments are identified to be mobilised at site.
