1. NAME OF PAPER :
MODERN TECHNIQUE OF CONSTRUCTION
2. DESCRIPTION OF WORK:
Use of Tunnel form for the construction of earth quake housing project in Republic of Turkey in 2001
3. METHODOLOGY ADOPTED IN EXECUTION
i. TUNNEL FORM
Form work is one of the most important factors in determining the finished appearance of in situ construction, strength & durability of the structure. Yet the role of the form work and the choice of the correct form work system have been subjects neglected in the construction industry. Today the trend in the construction industry is towards reduced construction time and cost, improved work place safety and standardization. In the recent past, the incidents of natural calamities like earth quake etc have become were frequent. The quick re-habilitations of the victims is a long challenge being faced by most of the countries.
To catch the above trends, it is imperative to develop form work systems which are productive, quick and easy to erect, quick and easy to strike, reusable at least more than 100 times and cost effective, tunnel form system is one of the such systems. This is a method in which the walls and the slab in a single operation with collapsible ensuring easy workability. In this system the construction time is much shorter than the conventional methods. Several studies shows that almost 50% of the time is saved compared to additional methods for completion of the project thereby reducing overall cost and risk of prolongation of duration. ii. USE OF TUNNEL FORM
- Fast construction fits to tight construction schedule.
- One set of tunnel form can provide a for half day cycle in place of 20-25 days cycle with conventional methods.
- Saving through reduced construction time. No effect of price hike
