- 1. PREFABRICATION Prefabrication is thepractice of assembling components of a structure in a factory or other manufacturing site and transporting complete assemblies or sub assemblies to the construction site where the structure is to be located. TRADITIONAL METHODS OF CONSTRUCTION Foundations are laid , walls are built , roofs are added and then the interior of the building beings to be created . MODERN METHODS OF CONSTRUCTION . Modern methods of construction are innovative ways of building structures. Which are increasingly being used in the construction industry . . Modular buildings . Flat slab construction . Twin wall construction . Hybrid Construction MODULE NAME- TOPIC - SUBMITTED BY - HARSHIT GARG 20DARC04 SUBMITTED TO – AR. VIVEK PAINULI LINGAYAS VIDYAPEETH
- 2. OFF- SITE CONTRUCTION Offsite construction involves the process of planning , designing , fabricating , transporting and assembling building elements for rapid site assembly to a greater degree of finish than in traditional piecemeal on site construction . ADVANTAGES OF OFF - SITE CONTRUCTION . Moving the building process away from the physical site into a controlled factory environment has multiple advantages . . Efficiency and predictability . Safety . Sustainability . Less labour . Less training . No disruption to clients . MODULE NAME- TOPIC - SUBMITTED BY - HARSHIT GARG 20DARC04 SUBMITTED TO – AR. VIVEK PAINULI LINGAYAS VIDYAPEETH
- 3. ON – SITECONSTRUCTION . Schoolhaus DISADVANTAGES OF OFF - SITE CONTRUCTION . Suitability depends on location . . Changes in design and plans are not possible once the project starts. . Demands extreme detailed planning. . Customization in modular construction is limited. . Demands proper and more communication between on site and off site construction. On – site refers to the traditional construction method in which structures are built sequentially in their permanent location.

- 4. ADVANTAGES OF ON- SITE CONTRUCTION . Weather Conditions . The on – site construction is highly influenced by weather conditions . Safety concerns – Compared to off- site or modular construction , on – site construction demands high safety and precautions. DISADVANTAGES OF ON - SITE CONTRUCTION . Design construction . Alteration after construction phase . Construction in tight urban areas. . Easy Renovation . Weather conditions . Safety concerns . Project not influences by weather . Management of timeless. AAC BLOCKS Autoclaved Aerated Concrete Blocks are fast replacing traditional bricks in the construction industry. AAC is a foam concrete material that is up to three times more lightweight than regular bricks. and hence is easy to handle and use too. AAC block prices range anywhere from INR 2000 to INR 4000 per cubic meter , depending on the manufacturer you buy it from . As expected the cubic meter price will vary depending on how many prices you buy. MODULE NAME- TOPIC - SUBMITTED BY - HARSHIT GARG 20DARC04 SUBMITTED TO – AR. VIVEK PAINULI LINGAYAS VIDYAPEETH

VIVEK PAINULI LINGAYAS VIDYAPEETH ADVANTAGES OF AAC BLOCKS # Thermal efficiency is one of the biggest advantage of these AAC blocks. # They keep the house pleasant during both summer and winter and reduce heating and cooling loads. # The handle fire better than traditional bricks. # These blocks are up to 3 times lighter in weight than traditional clay or cement blocks. # These porous and airy material last really long and are not much affected by climatic change. DISADVANTAGES OF AAC BLOCKS # Improper installation can cause cracks in the structures of the blocks and this will affect the final finish of the building . # The porous material of AAC blocks means that they have to be handled carefully during loading and unloading . # The fact that these are lightweight may make the labourers to handle them casually causing unwanted breakage. # AAC block price vary with the quantity you order. # Not any mason can lay AAC blocks. These needs to be done only by experts. # AAC block cannot handle heavy loads and are called non bearing materials . These should be mostly used for partition walls. DIFFERENCE BETWEEN AAC BLOCKS AND BRICKS AAC BLOCKS BRICKS # AAC blocks are in lightweight up to 3 times more lightweight than traditional red bricks and are easy to handle # Each of the AAC block can weigh anywhere from 3 kg to 15kg depending on the size of the individual block. # AAC block are very large in size. # AAC blocks are usually uniform in size and don’t come with rugged or rough edges that need to be trimmed. # The construction process is relatively quicker. # Red bricks come in different weights depending on seller. # The average weight can range between 2-3,5 kg for one block. # Red brick are smaller in size # The size and shape of red brick can be slightly different as they are mostly handmade. They also have rough edges that need trimming before use.
