Critical Path Method (CPM) is a project modeling and planning technique that the military and major US companies developed to manage the manufacturing processes of sophisticated weaponry.  Now, CPM is used in all forms of projects.  Any project with interdependent activities can apply this method of mathematical analysis. 

During the execution of a project, procedures for project control and record keeping become indispensable. These tools both record all financial transactions as well as give managers an indication of progress and any problems encountered on the way. By recording all financial transactions, organizing them and comparing them to the estimate (or budget), the prudent contractor can identify any areas that may be costing more than was anticipated in the bid. The compilation of this data is called a cost report.

Every Washington homeowner should be aware of vapor drive.  Not only does this phenomenon draw heat out of your house, but, without proper built-in protection, it can also lead to enough moisture build-up in your insulation to cause rot and mold.  

What is vapor drive?

Vapor drive occurs as warmer, more humid air is drawn to colder surfaces and then penetrates (or "drives" into) insulation. Temperature has a heavy influence on vapor: hotter water vapor is better at penetrating barriers than cooler water vapor.

The construction process has evolved over decades of problems occurring and people finding ways of preventing them.  The resulting traditional roles and responsibilities are recognized by reputable organizations like the American Institute of Architects (AIA) and Associated General Contractors (AGC).

Here you have a basic run-through of the steps you will go through, start to finish.
