After talking with you at length about what you are looking for, the professional will begin developing design drawings that become progressively more precise.

 

The first set is called rough or schematic sketches. These basic, un-detailed drawings show the essential outline of the project and changes are still easy to make.

Next come preliminary drawings. They are done to the same size and scale as blueprints but contain less detail and technical information. You should make any changes now while they can still be done inexpensively on paper. Also make sure everything you asked for is in the drawings and that other products aren't substituted.

The final plans are called working drawings or blueprints. With the exception of minor changes, this is what gets built. Blueprints come in a set and contain precise dimensions, lists or schedules of equipment, details of building directions, materials to be used and the work the contractor and subcontractors must do. They also provide the information that contractors use to make their bids. And remember, a good deal is not the lowest possible price...it's getting what you want at the price you agreed to pay.
