CIVIL WORK IN THERMAL POWER STATION

Till date we have discussed about the major construction equipment  required  for a project like big thermal power station .We hope this has gone well with the readers . Now we will discuss about the process of civil work i.e how to execute the same and what are the information required for the construction people.

Let us write the name of civil works exist for the project broadly can be termed as scope of work.

a. Plant 'General Layout Plan' drawing with coordinates of roads, boundary wall, buildings and facilities, piping/cable corridors, railway lines, green belt, etc. Initially this was made for project appraisal now more detailing to be done for actual purpose of work. It has been in India " GLP" goes into revision up to 9 times to make it final. All construction should have the latest copy of the GLP for reference.

1. GLP should take care all statutory implications ( acts /laws /by laws /local by laws) including safe distance from one plant to another etc.

2. Face of the building will be such a way that it is 25M away from double road and 20 M away from single road.

3. The area for construction/erection facilities like lay-down, pre assembly, offices and stores is to be

     marked specifically beside all permanent facilities.

4. No permanent facilities in safety Zone like H2 plant , Oil storage tank etc.

5. Transportation inside the plant by road or by rail should be clear. Road should be available to all facilites for fire tender movement. 

b. Geotechnical Investigation  :- Like GLP a broad Geotechnical investigation was carried out during apprisal stage to enable civil experts to estimate the cost and time to be taken for the project.Once the project is awarded then detailed testing is to be carried out for designing purpose. A comprehensive report will be prepared by executing agency who are expert on this. Here we are giving a short description of soil investigation . For detail you have to refer college books or standard published by respective country. 

-The Diameter of Boreholes will be minimum  150mm in Soil

- The Diameter of Bore holes will be minimum   76mm in rocks.

- The sampler Diameter will be  90 mm .   

The above figures are generally followed in India. 

The above picture shows the exposed head of piles to be removed  by pneumatic chisel and also gives you and  idea  of raft foundation on pile head.  This is for new comers who will come to know the site operation. This has nothing to do with SI .
