Constructability is an important objective in the whole phases of a construction project, and experts with knowledge and experience play an important role in achieving superior constructability. Constructability analysis will help to eliminate hidden costs and change orders, ensure schedule, improve construction quality and enhance safety in construction project. This research is undertaken to conduct a constructability analysis of monorail project. We identify comprehensive factors which influence monorail project constructability during project planning, design and field operation. Through literature review and case study, a systematic approach and techniques to improve constructability in monorail project will be developed. Finally, we further develop a practical framework for constructability implementation in monorail project.

Salient features of Monorail system:

1. In Monorail System train runs on a narrow Guideway Beam, wheels of which are gripped laterally on either side of the beam.

2. Monorail is a Light Weight System and its cost of execution is less compared to heavy rail systems and it takes approximately 1.5 to 2 years for execution.

3. Mono rail System requires 1.00 m wide space (Column Size 0.8 m X 1.5 m) the space of a footpath or a divider and it rests on a single pillar of height 6.5 m

without disturbing the existing traffic.

4. Capacity of 4 cars Monorail System is 8000 to 12000 PHPD.

5. Monorail System can achieve ± 6 % gradient and turning radius upto 50 m.

6. As compared to other systems Monorail produces less noise and is eco-friendly

and hence easily acceptable in dense residential locale.

7. Monorail System is in use in Tokyo (Japan) from 1963, in Kuala-Lumpur

(Malaysia) for last 5 years and in china for last 3 years.
