How To Understand Blueprints

 

Since the beginning of the humanity, men have always wanted to protect themselves from the outside conditions, but also from their enemies. Plans were not always needed, but in order to build a solid structure, a good engineer and a good architect are required. In North America, the building need to respect the norms and standards established by experts due to the reason that climate might be rough at any time. In fact, blueprints are definitely important to visualize the project in order to respect those standards and ultimately to build the project. In the following text, formats, measure systems, scales and the different kinds of blueprint will be discussed.

 

First of all, there are multiples formats for a blueprint which goes from A0 to A10. To give an idea, the A0 format is 33.1 inches X 46.8 inches large and is generally used by the architects or the engineers. The foreman will most likely uses the A1 format due to the fact that it is half of the above-mentioned surface. As mentioned earlier, in North America, things are not the same. There are two different measure systems; when it comes to building a house, blueprints are mostly in the Imperial System which is defined by inches and feet. Then, there is the International System which is in millimetres and meters. The International System is always used for commercial projects for it precision, but also for it ease to be understood.

 

On each page of the blueprint, there is a small revision block along the margin that shows all of the dates as well as the name of the client, the architect and multiple other important information. Generally, the scale is indicate under the draw or will be on the bottom right of the block. Scales on blueprints are indicate this way: 1: 100. It means the draw is reduced by 100 from it real dimension in order to take place on a sheet. Building plans are not perfect and will most likely evolve over the life the project.

 

There are different kinds of blueprints starting from the Site drawing to the mechanical plans. In fact, approximately 8 different kinds exist. First, there are the Site plans that locate the footprint on the actual site, the Civil drawing, the Structural plans that describe the foundations work, the Floor plans,  the Roof plans, the Wall Sections, the Electricity plans and finally, the Mechanical plans. In a residential project, plans such as the electricity and the plumbing are not required due to the fact the norms and standards are not as restricted as the commercial ones. Blueprint are easily recognizable. For example: the Electricity ones are paged this way in the bottom left of the block: E-1, E-2… The Structural ones will start with the page S-1, S-2. Finally the Floor plans are the most important in a residential and commercial project. All the dimensions required to build the project are found in these plans. Also, a legend is mostly placed next to a drawing, depending on the architect, that actually helps to understand all of the materials shown in the plans.

 

In conclusion, blueprints such as Floor plans and Wall section are not only used to visualize the project, but also issued for permit plans, to review with city planners in regard to zoning and issued to establish the construction budget. Depending of the complexity of the project, the measure system will change and be indicated in the block along the margin. Finally, building plans are not static and will typically evolve the life of a project.

Comments

Good mapping sentence in your introduction. It separates well every subject.
To continue with your introduction, the statement of intention does not appear clearly. For the body text it should had been a good idea to separate in two paragraphes the formats and the measure systems.
The subject is well explained and extremely interesting because it is different from others texts.

I found your introduction very interesting, it started the text on the right way. However, I think that when you explain the scale, saying that one centimetres on the plan equals to a 100 centimetres on the real building would have been a better way to explain it. But I also understand that you wanted your text to be easier to understand and you succeeded because I think that even a non-expert can understand it and learn. Overall, I really liked your text it was easy to understand and interesting from start to finish and even thought I have read some building blueprint I have learn a few things.

Very good text! You define very well all the technical vocabulary so your text is easy to understand. This is good because I am not studying in your field so I did not know the technical terms but you made it clear as water in your text. Otherwise, I would have prefer more visual,like a photography, so your text will be more attractive and dynamic. Exept that, you did a wonderful job and I learned new skills by now because of you so thank you.
