Prefatory Note. - Part I was intended to initiate the student in the fundamental principles of specification writing, by setting forth the nature of the preparation desirable and necessary for successful work. The entire field was by no means covered, nor was it the intention to state the only lines which could be followed.

Part II has been compiled from various sources with the intention of showing different phases of the work, and aiding those students who have carefully worked out the more fundamental lines.

Because some things are stated differently in one part from the other, is no reason for considering either line wrong. No one set of rules or directions will apply to all cases; and therefore the differences between the two parts, it is believed, will lead the student to compare in each case the two lines, and choose the one best adapted to the case he may have in mind, or else to go on and work out some third or independent line which will better than either fit the case. The man who thinks and reasons, provided he is well grounded in fundamentals, will rarely make a mistake.

A Specification is a statement of the conditions under which a building is to be constructed, and of the items necessary therefor which are not indicated on the contract drawings.

A Contract is a detailed statement of the agreement between the Owner and the Builder, for the execution of the project as required by the drawings and by the specification.
