What are the main functions of construction drawings, construction specifications and construction atlas in building construction?

Of course, I'm just talking about the main characters.

Construction drawings: including construction drawings, structural construction, HVAC, water supply and drainage, electrical and other construction drawings. Look at the words and you will know the general meaning. Without drawings, how can we know what to look at, where there are walls, columns and beams, how thick the walls are, how big the columns are and how high and wide the beams are? How to set the water supply and drainage pipeline route has drawings!

Construction specification: of course, it is to guide the construction, standardize the construction and implement the regulations. To put it bluntly, "cutting corners" is not appropriate, hehe!

Atlas: With the development of architecture, China has popularized the representation method of floor plan, and many things on the plan are brief. By looking up the atlas, it is a bit like the annotation of classical Chinese, standardized and refined. Some detailed components do not need drawings, such as septic tanks. You don't need to draw its details on the drawing, just say a model. You can consult the septic tank atlas issued by the state and carry out construction according to the model in the atlas.

This is just a personal metaphor, I hope it can help you as a whole, and I hope it can be adopted satisfactorily!
