Declare Joshi Mutt as ‘Neo Construction Zone’: Central Institutions

Dehradun: Joshi Mutt is more than its carrying capacity and should be declared. Zone About “no new construction”, says the National Disaster Management Authority in its 130-page ‘Post Disaster Need Assessment’ (pDNA) reports of the ‘sinking’ of the town. This is one of eight reports on Joshi Math, each by key Central Scientific and Technical Institute, which the state government has not made public for the past several months.
Days after the Uttarakhand High Court questioned the state’s decision to keep the reports out of the public domain, TOI exclusively accessed their recommendations, which the government had kept ‘secret’ for the past several months.
In January this year, eight institutions – Central Building Research Institute, Geological Survey of India, Wadia Institute of Himalayan Geology, National Geophysical Research Institute, Central Ground Water Board, Indian Institute of Remote Sensing, National Institute of Hydrology And IIT Roorkee – were. A mandate was given to ascertain the causes of landslides in and around Joshi Mutt and take remedial measures.

They submitted their preliminary reports to the National Disaster Management Authority by the end of January. The reports were later shared with the state government but never made public. Last week, copies of the reports were placed by the state government in a sealed envelope for consideration by the Uttarakhand High Court.
Among the many observations and recommendations made by the experts of the higher institutions, the main ones focused on the city’s carrying capacity and poor construction design and soil bearing capacity. Remarkably, the town is built on moraine or loose soil deposited by landslides.
“Joshimath is far beyond its carrying capacity, and the area should be declared a new construction zone,” the National Disaster Management Authority (NDMA) said in its report.
As of the 2011 census, Joshi Mutt had a population of 16,709, with a density of 1,454 per square kilometer. According to the district administration, the estimated population of this fragile city is now between 25,000 and 26,000. In its 180-page report, the Central Building Research Institute (CBRI) questioned the current construction practices at Joshi Math and called for a review of town planning principles for town development here and in similar hilly areas of the Himalayas. Recommended.
CBRI concluded that good construction typology, practice, materials, regulatory mechanisms and awareness among stakeholders based on geo-technical and geo-climatic conditions are essential. In a key recommendation, the Roorkee-based body also sought a plan for “phased de-densification of Joshi Mutt and similar locations”.
The Geological Survey of India (GSI) report stated that the density of recent ground cracks was higher in areas that are densely populated and dotted with multi-storied buildings. The same has happened in areas like Manohar Bagh and Singhdhar where more and more ground cracks and civil structures have been damaged.
The GSI report states: “Heavy loads from a dense construction of massive high-rise buildings of heterogeneous colluvium debris, saturated with shallow groundwater, only increase the shear stress on the slope, thus Deficiency increases in these areas.” The fissures that appeared earlier this year and forced many families to leave their homes, were mostly associated with a 50-60 meter wide linear array in Manohar Bagh, Sunil village, northwest-southeast of the town. Singh covered Dhar and Marwari wards. Settled
After a detailed safety assessment of 2,364 buildings at Joshi Math, CBRI scientists found 20% of the buildings “unusable”, 42% “requires further evaluation”, 37% “usable” and 1% “needs demolition”. “.
Meanwhile, the PDNA report prepared by the NDMA-led team identified potential negative impacts on the environment from future large-scale reconstruction activities at Joshi Mutt. “It is imperative that these rebuilding programs focus on green design, appropriate technologies and the use of limited masonry,” the report added.
The central government had recently given in-principle approval to a Rs 1,465 crore package for the rehabilitation and reconstruction of the Joshi Mutt.
