Abstract - The development and application of onsite and precast building is very different in the various countries. Traditionally, cast-in-place construction has been primary method for buildings. Prefabricated systems are a growing technology to aid in rapid building construction to minimize delays. Prefabrication also improves the quality of product because elements are manufactured under controlled conditions in the plant and high-performance materials may be used during casting. Prefabrication also improves safety in the work zone by reducing the amount of activity that is required over traffic or at high elevations to construct the high-rise buildings. Prefabricated Building construction can be used for new projects as well as building rehabilitation. Prefabricated building construction will result in rapid construction and minimized delays during the course of project. Fast track construction systems use prefabrication components to rapidly erect a construction.
of materials, labour, and technical skills. Advantages of prefabrication are multiple as the components are readymade and self-supporting, shuttering and scaffolding is eliminated, with a saving in shuttering cost. In traditional construction, the repetitive use of shuttering is limited, as it gets damaged due to frequent cutting, nailing, etc. On the other hand, the mould for the precast components can be used for a large number of repetitions, thereby reducing the cost of the mould per unit. In the prefabricated housing system, there is saving of time, as the elements can be cast beforehand during the course of the foundation being laid.

1.2.4 1.INTRODUCTION Now a days there is great boom in infrastructural development that to in a manner of fast-track construction. Today the need is to save time and to optimize the utilization of resources. This method requires large amounts of time and labor at project site. Buildings form an important component of infrastructure, and require huge investment. Overall, building construction is a labor-intensive, lengthy process primarily due to curing times for concrete and formwork construction. Using prefabrication in a project allows to reduced time duration. This means that the impact of the site on the local environment is for a shorter period of time. Using this prefabricated building components in building construction projects can reduced the curing times from the critical path of the project and eliminating the need for temporary formwork. Thus the purpose of this project is to determine prefabrication and onsite trends and effects on the construction workforce. Therefore, using of these techniques to reduce project duration, & costs. Study of comparison between onsite construction and prefabricated construction and show the graphical representation. 1.1 Aim The aim of this project is to determine the prefabricated building techniques over a conventional method. Prefabrication techniques have many merits, like availability Š 2017, IRJET

To study the Conventional &prefabricated building construction. To Analyze the time and cost required for various building components. To compare the conventional and prefabricated building construction with respect to time and cost. To optimize blend of conventional and prefabrication techniques in construction. Above objectives will be achieved by taking a case study.

1
One work cannot start until the previous work is completed.
Work occur simultaneously, and the erection process is fast.
2
Process can be easily delayed by adverse weather or scheduling conflicts.
No impact on scheduling of prefabrication manufacturing.
3
Most of onsite construction procedures depend on manual method.
Prefabrication construction procedures depend on automation.
