Blueprint for House! Need? Necessity & How To Devise it?

Blueprint for House! Need? Necessity & How To Devise it?

    Blueprints of house construction are used by the builders and contractors as a customized plan to guide them on how to build or remodel a home. Many house owners are not aware of the construction and blueprints which could cause miscommunication leading to over-expenditure.

What do you mean by House construction Blueprints?

    Blueprint is a type of construction drawing that shows how a building can be designed, what materials to be used and what are the features like doors, windows, sinks, and appliances to be used.

    These construction plans have to be with you and can be modified if needed later. The blueprint aims to make sure that the project has fulfilled the required compliances and building codes. 

    Blueprint reading is an important skill that workers in the architecture design and construction industry need at each step of the building construction process.

Blueprint Basics

    Blueprint is typically drawn on a 1/4 inch scale which means each quarter-inch on the plan equals 1 foot of the completed structure.

Main Features of a Blueprint
The anatomy of a blueprint includes:
1. Title block:

The title block usually contains-

  • Company Logo & Contact Information
  • Customer Name
  • Architect Name
  • Project Name
  • Site Address & Site Location
  • Drawing title
  • Date drawn
  • Number of sheets
  • Approvals
  • Scale

The title block contains important baseline information about the project.

2. Revision Block:

    The revision block mentions any changes that are done to the drawing carrying the Date, Description of the Change, Name or Initials of the person doing the change.

    The revision block section is included in various parts of the plan. When the blueprint is first drawn, the revision block stays empty and awaits revisions to the parts.  The things go on entering as the changes are made to the as-built drawings.

3. Grid System:

    Just like a map, the blueprint sheets carry a grid system that is both horizontal as well as vertical edges. That is the numbers are on one axis and letters are on the other. That helps in referencing a particular spot on the drawing.
4. Notes & Legends:

    Symbols, abbreviations, notes, and other related information to each particular drawing are mentioned at the bottom of each floor plan. This becomes easier to decode the symbols of drawings. 

    The legend is critical because the person can easily get confused while reading the blueprint as different architects & engineers usually produce them. Symbols don’t mean similar things for the construction workers working in different specialties.  

    Besides this, there are some custom symbols are used that are not seen in other projects.

Examples of such symbols: 

  • Compass Symbol - Building Orientation
  • Straight Line – Indicating a door and the arc showing how it will open.
  • Thick lines - Denoting exterior walls
  • Triple line – Location of the window
  • Stove, Toilet, tubs are drawn in simple outline form.
5. Drawing or plan, Elevation & Sections:

    The main area filling the center of each blueprint sheet is assigned to the drawing plan, Elevation & Sections that illustrates a particular view, feature, and system of the project.

6. Key Plan & Plot plan:

    Key plan should be provided with the building location, Septic tank, septic tank location along with the plot plan.

NOTCHES AND WEIRs

Image
   NOTCH ,WEIR AND ITS TYPES Notch A  notch  may be defined as an obstruction over which the flow of liquid occurs   In case of measuring tank or reservoir, the opening is provided at the side of the tank such that the liquid surface in the tank is below the top edge of the opening. Weir A  weir  is a notch on a large scale used for measuring the flow of a river, canal etc. It is a concrete or masonry structure of substantial breadth built across the river in the direction of flow. This allows the excess water to flow over its entire length to the downstream side. Thus a weir is similar to a small dam constructed across the river, with a difference that the excess water flows downstream only through a small portion called  spillway  and in case of weir, the excess water flows over its entire length. Nappe and crest The sheet of water flowing through a notch or over a weir is known as  nappe  or  vein . The bott...

THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS

 THE BASICS OF REBAR: A COMPREHENSIVE GUIDE FOR BEGINNERS The Basics of Rebar If you have ever wondered what gives strength and stability to the concrete structures that we see around us, the answer is (most commonly) rebar. Rebar, short for reinforcing bar, is the steel rods that are embedded in concrete that provide tensile strength to what is actually and prevent cracking. Rebar comes in different shapes and sizes, but the most common type is deformed steel rebar, which has ridges or indentations along its surface to create a better bond with the concrete. Deformed steel rebar has been used in the construction industry for over a century, and it has revolutionised the way we build. With rebar, and using elements such as beams,  beam ties , rebar mesh, and reinforced walls, we can create taller, stronger, and more durable structures that can withstand natural disasters, environmental changes, and human activities. Some of the most iconic buildings in the world, such as...

What are different diameters of steel used in construction field?

         In the construction industry, the appropriate selection of materials is crucial as they form            the fundamental basis for determining the strength and durability of structures. TMT (Thermo-Mechanically Treated) Steel is one of the essential components in construction as it stands out for its exceptional strength and ductility in building structures. Thus, contributing to the prolonged longevity and durability of the structures. In this article, we will delve into the different sizes of  TMT steel bars  and their different uses in the construction industry. These TMT Steel bars come in different sizes based on their varied diameters. The different diameter of steel bars are as follows: 8mm Steel Rod 10mm Steel Rod 12mm Steel Rod 16mm Steel Rod 20mm Steel Rod 25mm Steel Rod 32mm Steel Rod, etc TMT bars of varied sizes, play a pivotal role in diverse infrastructure initiatives, the versatility of TMT bars is ...
