This document discusses prefabricated building construction. Prefabrication is defined as assembling components of a structure in a factory and transporting them to the construction site. There are benefits to prefabrication such as being eco-friendly, providing financial savings, allowing flexibility, ensuring consistent quality, reducing site disruption, shortening construction time, and improving safety. The concept of prefabrication involves producing precast concrete units in a factory, transporting them to sites, and erecting them, which requires casting, curing, and transportation/erection stages.

3. PREFABRICATION DEFINITION
❖WHAT IS PREFABRICATION ?
✒PREFABRICATION IS THE PRACTICE OF ASSEMBLING COMPONENTS OF A
STRUCTURE IN A FACTORY OR NOTHER MANUFACTURING SITE, AND
TRASPORTING COMPLETE ASSEMBLIES OR SUB-ASSEMBLIES TO THE
CONSTRUCTION SITE WHERE THE STRUCTURE IS TO BE LOCATED.
✒ IT IS COMBINATION OF GOOD DESIGN WITH MODERN HIGH PERFORMANCE
COMPONENTS AND QUALITY CONTROLLED MANUFACTURING PROCEDURES.

4. PREFABRICATION CONCEPT
❖ PRIFABRICATED SECTIONS ARE PRODUCED IN LARGE QUANTITIES IN A FACTORY
AND THEN SHIPPED TO VARIOUS CONSTRUCTION SITES.
❖PRECAST CONCRETE UNITS ARE CAST AND HARDENED BEFORE BEING USED FOR
CONSTRUCTION.
❖SOMETIMES BUILDERS CAST COMPONENTS AT THE BUILDING SITE AND HOIST
THEM INTO PLACE AFTER THEY HARDEN. THIS TECHNIQUE PERMITS THE SPEEDY
ERECTION OF STRUCTURE.

5. PREFABRICATION CONCEPT
❖ THE PREFABRICATION AS DEFINED WILL BE
DONE IN TWO STAGES MANUFACTURING
AT FACTORY CONDITION AND ERECTION
(MANUFACTURE) OF COMPONENTS AT THE
REQUIRED LOCATION.
❖THIS REQUIRES CERTAIN STAGES OF
PREPARATION. THEY ARE
1.CASTING
2.CURING
3.TRANSPORTATION AND ERECTION
❖ CASTING :- PRECAST COMPONENTS ARE CASTED WITH CONTROLLED CEMENT
CONCRETE IN MOULDS OF REQUIRED SHAPE AND SIZES.THE VIBRATOR IS USED TO
VIBRATE CONCRETE AND THIS REMOVES ANY QUERY INSIDE THE COMPONENTS.
