The efficiency of fabrication and erection in structural steelwork dictates the success of any project involving steel- intensive construction. Current practices of fabrication and erection of steel structures in India are generally antiquated and inefficient. Perhaps, this inadequate infrastructure for fabrication is unable to support a large growth of steel construction. In India, the fabrication and erection of structural steelwork has been out of the purview of the structural designer. Nevertheless, in the future emerging situation, the
entire steel chain, i.e. the producer, client, designer, fabricator and contractor should beable to interact with each other and improve their efficiency and productivity for the success of the project involving structural steelwork. Hence it becomes imperative that structural designers also must acquaint themselves with all the aspects of the structural steel work including the “fabrication and erection,” and that is the subject matter of the present chapter to briefly introduce good fabrication and erection practices.
Structural steel fabrication can be carried out in shop or at the construction site.
Fabrication of steelwork carried out in shops is precise and of assured quality, whereas field fabrication is comparatively of inferior in quality. In India construction site fabrication is most common even in large projects due to inexpensive field labour, high cost of transportation, difficulty in the transportation of large members, higher excise duty on products from shop. Beneficial taxation for site work is a major financial incentive for site fabrication. The methods followed in site fabrication are similar but the
level of sophistication of equipment at site and environmental control would be usually less. The skillof personnel at site also tends to be inferior and hence the quality of finished product tends to be relatively inferior. However, shop fabrication is efficient in terms of cost, time and quality.
Our structural steel fabrication services are compliant for industry and can easily meet the needs of a variety of businesses within the power generation industry, including coal and natural gas power plants. Power generation projects require the great experience and specialized expertise from the structural steel contractor.
