Nepal Engineers Association has released the conclusion that government structures including the buildings of Singha Darbar, Supreme Court, Kathmandu District Court and Nepal Bar Association are not suitable for immediate use.

After the initial inspection of the government structures damaged during the movement led by Zen-G and the subsequent demonstrations, it has been stated that the damage observed in these buildings is serious and further technical evaluation and repairs are required for safe use. According to engineer Anil Manandhar, deputy secretary general of the

association, the damage was more because these structures burned for a long time in the fire of more than 500 degrees. According to him, in this situation, the carrying capacity of the building decreases up to 60 percent.

'In the past, Nepal had not suffered such a loss. Even if there was a fire, the fire brigade would come immediately and extinguish the fire within a few hours, but there were also buildings burning for two days," Manandhar said. However, the union and the building department are not clear about how much damage will be strengthened (retrofit) and how much damage will be reconstructed.

Now a red sticker has been placed on Supreme Court, Kathmandu District Court, Bar Association. But putting a red sticker does not mean that the building must be demolished . The association stated that the stickers were put on by asking the relevant agencies to take precautions as it would be a threat to public safety if it is put into immediate use without reconstruction or strengthening.

'For the immediate means not to use on the basis of what the eye sees . Due to the damage of the ground floor, even if the upper floor is fine, it cannot be used,' said Manandhar, 'we will re-study what materials have been used and the condition of the rods and cement, which structure can be strengthened and used, and which should be completely reconstructed . According to him, it will be decided by looking at the economy. He said that if the cost of building a new structure would be the same rather than retrofitting, it would be better to rebuild it. Manandhar said that since Singha Darbar is of archaeological importance, it should be retrofitted regardless of the cost. According to

building consultant Satakshi Mishra, it is necessary to check the bearing capacity of the rod lab at the place where the slope is broken and the rod is seen. She said, 'The rod can withstand temperatures up to about 200 degrees Celsius . But after reaching above that, the iron starts to stretch and its load-bearing capacity decreases .'

Most of the houses in Nepal are made of wall system or pillar system . Pillar systems are more likely to be rebuilt if fire damage occurs around the rod. But can be retrofitted in case of normal burn . According to him, the bricks used in the wall system house can last up to about 800 degrees Celsius, but after exceeding 300 degrees, the cement paste that joins the bricks becomes loose . When it reaches above 800 degrees, even the brick starts to crack .
