Following up on the previous post we are starting a sequence of posts showing various stages of the construction process of the house in Anna Nagar / Chennai. Featured here is a set of photos of the foundation works.
Initially it was planned to have individual footings (up to a depth of 8′) joined by a plinth beam. After the first excavations were under way, we realized that the ground water level is very high and felt that pile foundations to a depth of 45′ would do a better job on the long run.
Given the size of the property (80′ deep and 45′ wide) with buildings almost bordering all sides of the plot, the actual work was quite time-consuming and took more than three months. Finally by August the work on the pile heads could start after which we had a steady and fast progress with the last slab being cast in the next days.

Credits to Harinarayanan Structurals for their organized site work. Since their team took over the construction work in late June 2013 the site progress has been tremendous.
A photo from beginning of August shows the confined site with the plinth beam work almost completed and some column reinforcement coming out of the ground.

The next post will follow the construction process through until the preparations for the last slab (under way just now)…
