In building design and engineering, precision is a must that goes without saying. Every detail counts. A lawyer may lose the case of his/her client when he/she makes a mistake with his/her argument. A doctor will most probable kill a patient when he/she makes an error during a surgery or prescription. But this is nothing compared to the risk of an engineer's job. When he/she makes mistake, chances are, an engineering glitch will occur in his/her projects, putting the lives of the users of the infrastructure in peril.
Having this said, we affirm the previous claim: everything counts. Every subtle measurement counts. Every AC put counts. Every fire exit put counts. Every beam holding a structure matters. In engineering and architecture, there is no room for mediocrity.
This is the reason why engineers and architects use specialized tools in making their initial sketches and finalizing their finished blueprints. Some of them look unimportant (like colored pencils and eraser shields) but, hey, they contribute a lot to the final appearance of the drawings. Without colored pencils at first, it would have been probably very very difficult to determine which is which in a sketch. Likewise, without an eraser shield, it would also be difficult to erase highly specific portions of the plan.
Sadly, not every project managers are very keen with keeping high standards, especially in Third World nations' government buildings and infrastructure. You cannot blame them, anyway, since funds are hardly there to support projects. And let us not forget that these nations' top engineers and architects are trying to make a living abroad because of greener opportunities.
If only developing nations would pay much attention to their infrastructures (and engineers/architects), development would probably be faster.
