Common Hazards/issues normally countered at all construction sites:

Human error in rebar fabrication (manual).

Fig 1 : Incorrect bend

Compromise with safety and quality.

Procurement schedule delays affecting site progress, and thereby delaying project completion.

Inventory management. Capital locked in inventory.

Abstract
There are a great developments in the recent years like the high-tower buildings, offices, complex structures,or the concrete structures,etc. And the concrete lead for the better performance reducing the self-weight of the structures. As self-weight of the structure is vital for the structural safety. So for this lightweight concrete (LWC) has been used.The use of LWC is increasing for many structural purposes all around the world. LWC is used for fabricated structures which have good thermal insulation,better durability and are lightweight too. The constructional cost is the most important and essential factor for using LWC.The possible advantages of how to design the pre-fabricating structures is briefly scrutinized. The benefits of using this pre-fabricating material , to develop an eco-friendly regime in the environment and to control highly managed disposing of materials is examined.

Keywords: Lightweight concrete, Pre-fabricated materials, Economic Benefits.
