With 99.8 metres width and 353 metres length, the building claims to be India’s largest clear span building
  Interarch announced that in 2015 it has designed and engineered, manufactured and delivered largest clear span building in India for Ultratech Cement Ltd in Rawan. The building is spread over the area of 35,000 sq.m. Interarch’s scope of work included design and engineering, fabrication, supply and logistic, and erection of four buildings in Rawan, Chhattisgarh. The buildings required were clear spans buildings ranging between 62 metres, 85 metres, and 95 metres and 99.8 metres.
On the basis of customer needs and functional usage, Interarch’s expert design and engineering team proposed an open web portal frame structure for the 99.8 metres clear span building using CHS sections and other three buildings in built-up sections. The building was designed for the seismic zone 3 and IS 800:2007. The loading design has been applied on the structure in accordance with IS-875 (Part 1, 2 and 3).
Upon erection, the building spans 99.8 metres wide and 353 metres long, with a clear height of 24 metres at the peak.
Interarch certified builders and employees had to work under very stringent quality and safety conditions in line with the international standard to achieve many challenges at site. The erection of the 99.8 metres clear span building was done near three operating conveyer belts surrounded by heaps of coal, dust in the environment and lack of space to erect the building caused lot of difficulty to the erection team. Interarch team had to construct a cross over bridge, constantly spray water to keep the dust settled.  All workers wore face masks and safety goggles to tackle the dust.
Interarch deployed almost 15-20 dedicated safety and quality engineers at site to ensure the highest standards of safety and quality controlled execution.  The total time taken for erection of the building was 6 months.
