The saving in the total building weight is dramatic, from a total of 10,958 tons in a traditional R.C. slab-building to 8458 tons for a truss-supported-slab building. This is a saving of 2500 tons or 23.12  per cent. In both the building types, the weight of only the reinforcing steel and concrete, the structural component, has been considered and shown for easy and convenient comparison.

The comparative analysis of the two different floor systems, on a 20-storey building was done by generating a finite element model on ETABS (Extended Three Dimensional Analysis of Building Systems) software by a leading engineering firm in Dhaka and reviewed by two leading civil engineering professors in BUET (Bangladesh University of Engineering and Technology). The ETABS software is used by civil engineers in 160 countries of the world and is universally accepted as the construction industry's most reliable software. The building was designed for a location in Dhaka and the Bangladesh National Building Code (BNBC) guidelines were followed in the design.

The total cost, inclusive of construction materials and direct labour for the traditional 20-storey concrete building stands at Tk. 265,334,212. The estimated cost of a steel truss-supported floor of 20-storey building of the same area and layout is Tk.215,646,232. This means a saving of 18.72 per cent. The time to construct a truss-supported floor is reduced by 33 per cent as no shoring is required. If the time saving is factored as a cost element then the total savings will be even higher, over 20 per cent.

In Europe and North America and also in the Middle East truss-supported floors have become the norm and accepted method of building construction. In the last five years, truss-supported floors have made inroads and gained popularity in neighbouring India as well.
