Other part of civil work is structural work. We need to fabricate and erect around 30,000 MT of structure in a power house with standard sections of structural materials. During land discussion it was mentioned that how much land is required fabrication of them. fabrication of columns , beams , purling , roof beam , racks , galleries , gusset plate etc are to be fabricated at site. We need to to arrange two to three Numbers gantry crane to handle ,move this structures.Beside that we need
around 100 welding machine in fabrication yard to do the fabrication . Around 15 nos PUG machines are required to complete the gas cutting operation. It is to be noted raw materials in plates of different thickness and standard structural section will be used in fabrication.
It is a pertinent question that why such a big fabrication yard and set up is necessary at site. It is observed that some of the fabricated system are very big and very difficult to transport from one place to another . The items are columns , purling , racks so fabricated in total reduce the erection time . However for small project where such consideration are not there can be thought of . But in my thirty five years experience it is seen that fabrication yard are only at erection site. The layout of fabrication yard is very important not only for fabrication but also for transporting them to site. Earlier days it was found that temp. rail was laid and column etc transported on trolleys. But now a days high capacity trailers are employed. There are advantage and dis advantage of both the system but it seems to me that earlier system is cost effective but needs proper planning. Construction student may note it and plan their activity accordingly . Also they should keep an eye on layout of fabrication whether he is directly employed or indirectly associated.
Beside above one or two compressor are required for sand blasting , painting etc. Electrical connection either by 11kv/415 v or 6.6 kv/415 sub station or control panel is required to cater the requirement of electricity at different places . This is required careful planning . It has been observed that at Peak periods where we be fabricating 1000MT /per month then the load will be around 800 amp to 1000 amp peak .This include occasional stress relieving also.
This concludes major T&P requirement for Civil work in a thermal power plant. If any body can do some value on this it is welcome. We are looking forward towards the expert in civil engineering construction. Please keep this in mind that this blog is for newcomers in construction field so that they understand thermal power plant and construction . All experienced hands need do value addition to it.
