Structural Repairs



One of the principal concerns of this project were the large number of separation cracks in the floor and walls that were diagnosed in the condition mapping during the course of the project. On opening up of the plaster the cracks were inspected closely and the Structural Engineer Ummed Singh visited the site to complete the structural assessment and prescribe solutions for their repair.


October 2013 Site Meeting with Structural Engineer Ummed Singh to access the structural damage
The discussions with the structural engineer concluded that the building was not in any active structural distress and the cracks needed to be repaired and some masonry needed to be reset. We had two options for the crack repair, one of using proprietary structural solutions such as helifix beams which are imported from UK and increasingly used in restoration of monuments. This systems essentially is about inserting a stainless steel finned bar into the masonry and grouting it with silicon. There were two reasons that we did not adopt this repair methodology, one that we didnt agree in principal with the use of silicon grouts in this case and secondly the entire process of importing the methodology from UK cost more than 20 times the cost of doing things locally and secondly was not sustainable.

Instead we decided to work with simple principles of structural design and provide support and repair by rebuilding for the arch failures etc. Crack stitching by stainless steel plates was achieved by locally manufacturing the SS steel plates and carefully inserting them, into the cracked area and repacking the brickwork complete with lime mortar.

Ground Breaking Ceremony


The restoration project finally began in full swing in January 2014. Having planned the project, one of the most important task was to appoint a contractor who could implement our vision on the ground. The peculiarity of the project was that it was a conservation and restoration project with a very strong interior design component. Thus it was extremely important for the contractor to be someone who was proficient in the interiors as well as conservation.

The contractors for this project were chosen as "Paras Construction" run by a couple Shilpa & Muneesh based in Ghaziabad, a suburb of Delhi. Their speciality was interior design and build and being "hands on" contractors they were able to grasp the nuances of conservation work rather quickly!

As per typical Indian traditions, before the work on site began, a small pooja/ ground breaking ceremony was organised to take the blessing of  the almighty to ensure the smooth functioning of the project.
