56 columns or 40 columns?
The contractor who has been engaged to carryout construction on two sites (Sanjay Nagar Miraj, and Phase 1 of Indira Nagar Gharkul) as part of the Integrated Housing and Slum Development Program (IHSDP) in Sangli & Miraj has decided to revert back to Shelter Associates original design. Even though Shelter Associates had prepared a complete set of detailed structural drawings, the contractor had commissioned another design team to prepare structural drawings for these contracts.
Shelter Associates observed that the contractors design team had altered the structural design and highlighted this to the Sangli, Miraj & Kupwad Municipal Corporation (SMKMC) and the contractor; which prompted the contractor to conduct a cost comparison.
The contractor found that the Shelter Associates design is much more cost effective, provides more flexible residnetial units, provides a more efficient parking area, and is quicker to construct. This is all because the Shelter Associates design requires fewer columns, meaning fewer foundations, less excavation work, less concrete, less steel, and less labor; Shelter Associates design requires 40 columns per building (approximately 7 columns per residential unit) as opposed to the 56 columns (9 columns per residential unit) which were proposed by the contractors design team. The Shelter Associates design also provides a more flexible plan for the beneficiaries as it does not require the contractor to form a column in the middle of the residential unit.
Unfortunatly, the contractor had already started 10 of the 14 buildings at Sanjay Nagar Miraj before conducting the cost comparison. This means that 10 of the 14 buildings are being built using the less cost effective design which takes longer to construct.
