6. Building Components and Its Functions

Image
A building comprises several fundamental structural and architectural elements, each specifically designed to perform a primary function. Together, they ensure the structure remains safe, durable, and comfortable for its occupants. Building construction activities generally start with the lowest part and move upwards, broadly dividing a building into two main categories: the substructure and the superstructure. 1. Substructure (Foundation) The substructure includes all elements below the ground level that safely transfer the building's load to the earth. Foundation: As the lowest and most critical part of the building, it acts as the linkage between the structure and the ground. Load Distribution: Safely and evenly distributes the load from the superstructure to the soil. Anchorage: Secures the building against movement or overturning due to lateral forces like wind or earthquakes. Leveling: Provides a stable, leveled surface for the construction of ...

The National Building Code of India (NBC)

The National Building Code of India (NBC) . Initiated in 1970 and currently on its 2016 revision (NBC 2016), this comprehensive framework by the Bureau of Indian Standards (BIS) governs the design, construction, and safety of all buildings across the country. You might wonder why we don't just jump straight into drawing plans and learning about masonry. The reason is simple: NBC compliance is effectively mandatory . Local authorities like BBMP (Bengaluru), CMDA (Chennai), and GHMC (Hyderabad) incorporate the NBC into their local building bye-laws. If your designs don't meet NBC standards, you cannot get planning permissions or the Occupancy Certificate (OC) required to legally deliver a project. Here is why understanding the NBC is your absolute prerequisite for mastering the following construction and planning topics. 1. Definitions and Terminologies Before you can design a building, you must speak the legal and technical language of the industry. The Baseline: Part 1 ...

4. Types Of Building

Image
A building is a structure with walls and a roof situated in a specific location more or less permanently. Over history, buildings have evolved in various sizes, forms, and applications based on ground conditions, climate, construction materials, aesthetic considerations, and specific human needs. In civil engineering, buildings are systematically classified based on their usage (occupancy), the method by which they transfer structural loads, and their overall height. 1. Classification Based on Occupancy and Usage Buildings are primarily categorized according to the nature of their daily usage and the occupants they serve.  National Building Code (NBC) classify buildings into 9 distinct occupancy groups. Here is the comprehensive table detailing the sub-categorizations for each main occupancy group: Main Group Sub-Group Type of Building / Characteristics Group A: Residential Buildings A-1 Lodging and rooming houses. ...
