Construction Specifications Institute Masterformat was first published in 1963 and has been updated several times since.
The basic rule on what goes where between Drawings and Specifications is this:
what is best communicated in the specifications should be written in the specifications and what is best communicated by the drawings should be pictorially represented in the drawings.
Drawings should generally show the following information:
Extent, size, shape and location of component parts.
Location of matls, equip, and fixtures.
Detail and overall dimensions.
Interrelation of materials, equip., and space.
Sizes of equipment.
Identification of class of mat'l at its location.
Physical extent of alternates.
The specifications complement the drawings by describing..
qualities of materials, systems, and equipment; workmanship on-site and off-site fabrication and installation and erection.
Specifications should generally describe the following:
Type and quality of materials, equipment, and fixtures.
Quality of workmanship.
Methods of fabrication, installation, and erection.
Test and code requirements.
Gauges of manufacturers' equipment.
Allowances and unit prices.
Alternates and options. (greater or equal).
No matter how carefully the Project Manual and the Drawings are prepared, there are bound to be discrepancies. To resolve these conflicts:
Specification overrides drawing.

The AIS General Conditions, Paragraph .2, Document A201 requires amendment in order to resolve discrepancies.

The AIA (American Institute of Architects) classifies specifications as one of the contract documents. They are written for a wide audience to include:
1. Contractor - construct, manage, and direct construction
2. Estimator - Prepares the estimate based on specifications
3. Purchasing agent - Procures the material and equipment
4. Resident project representative - Inspecting and controlling the work
5. Owner - What they are buying and entitled to receive
6. Subcontractors - Readily discern the scope of his subcontract
7. Manufacturers - Grade and type are clearly defined.
The specifications alone are not the contract documents; they are one of the documents contained in the Master Format. The specifications address the following:
1. legal considerations
2. insurance consideration
3. Bidding Requirements (usually bound with the specifications)
4. Alternates
