Prefabricated Component Sizes and its Tolerances used in Prefabrication Construction and design techniques as per National Building Code The following tolerances are in the form of modular coordination, where tolerances are given as M, 0.1M , 0.5M etc as per NBC Question asked in universities are:- Describe tolerances and derivations and their permissible values for precast components

Topic Covered in this article: Modular Coordination, Basic Module, planning and design modules, & Modular grid system Modular coordination means the interdependent arrangement of a dimension based on primary value accepted as a module. The strict observance of rules of modular coordination facilitated, 1. Assembly of single components into large components. 2. Fewest possible different

HOW PREFABRICATION ? PREFABRICATION: IS CODES As in India there is no specific IS code but following can be used for prefabrication construction IS 15916: Precast Construction IS 875: Design Loads IS 456: Concrete IS 1893 and IS 13920: Seismic Design Aspects to be considered as per the Recommendation of IS: 15916: 2011 1 Effective utilization of spaces 2

NEED OF PREFABRICATION •Demand •Difficulty •Distance •Recurring Demand •Economy •Quality •Environment WHY PREFABRICATION ? ADVANTAGES OF PREFABRICATION •SPEED – 40% for single storied building 25% to 40% for multi storied buildings •Reduction in cost - 15-20% ( framework, shuttering, labor, material) •Disciplined use of scare materials - involve

WHAT IS PREFABRICATION ? The concept of precast structures also known as prefabricated/ modular structures. The prefabrication is the oldest and most successful construction techniques. Prefabrication is a practice of assembling components of a structure in a factory or other manufacturing site and transporting complete assemblies to the construction site where the structure is located.
