INTRODUCTION

Temporary supporting structures are those structures which are required in the routine building construction works or repair works. During the process of concreting work, temporary structures called formworks are needed till the concrete attains its full strength.

Similarly for laying of masonry work, plastering, painting and for temporary repair, some temporary structures are used which are called scaffolding.

During the process of excavation, or temporarily supporting a weak structure some temporary structures are constructed which are called shoring.

Sometimes there may be some necessity to strengthen the existing foundation or to undertake some repairs or to increase the number of floors or introducing a basement floor, some temporary structures are constructed which are called underpinning.
