The influence of time on cost is very significant, through interest rates, inflation and rentals. Since the choice between steel & concrete is steel the subject of an elemental and cost analysis leading to a cost per unit area measurement, the resultant bill of quantities does not embrace such time related cost as land fees and finance charges.This failure of cost analysis is to take into account the effect of faster construction time achieved for steel framed buildings gives a false picture of real costs.
Reduction of Foundation Cost:
The lightness of a structural framed building as compared to one with a concrete frame can result in lower foundation costs. Particularly where ground conditions are poor, this weight advantage can mean the difference between concrete and steel structure.
Maximum Floor Space:
High rental characteristics of any major city in the world today mean the maximization of floor space which is essential for profitability. Our structural steel work offers greater value for money on a net floor area basis with its wide spans and moderate sizes. The minimum column dimensions and long span beams permit maximum clear floor area and effective floor utilization and also where long spans are necessary, the cost savings between steel and other form of construction is unbelievable.
Salient Features of Steel Structures:
Steel build your structure in a quick manner than any other form of structure. The reasons lie in the very nature of our modern fabrication and erection processes, the essential feature of which is that fabrication is done entirely in workshops while foundation work is being carried out and that subsequent on-site resource requirements are minimized.
We consider fire protection measures while design and construction. A wide range of fully tested board systems (including pre-formed), sprays and in tumescent coatings is normally used. For multistory building a composite steel floor deck is widely used to permit substantial savings in erection time. The profiled sheets can be lifted and stacked in multiples with significant savings in crane time compared with pre-cast floors.
Width of Building:
The lateral width of a Building measured from out to out of steel lines.
Length of Building:
Distance between two end bay is summation of end bays and interior bays within the building is actually creates the length of building.
The first or last bay of the building as opposed to interior bay.
The distance between the center lines of two adjacent interior rigid frames.
Pitch or Roof Slope:
Roof slope is defined as the angle between the inclined roof surfaces to the horizontal surface and is commonly 1/10 but it may change due to demand the type and size of Building.
Pre-Engineered Building Series
Single Slope Single Span or Multi Span:
Single slope buildings may be either clear span or multi span. The most common conditions for using single slope buildings are whenever rain water drainage is required to be along one side wall of the building only. A common applications of single slope buildings are demount able buildings such as those use for site offices or camp accommodations. These are typical 3.6m wide, 12m long, with 2.4m eave height at the lower side.
Multi Gable Multi Span:
Multi gable buildings consist of more gable buildings sharing side wall columns. Although multi gable buildings are commonly used in many regions of the world.
