It is absolutely vital to create a comprehensive specification for any building project. To guarantee accurate costing, one cannot use general notes and specifications. As the word suggests, a specification contains specific information. For example, a door is not simply a door – it has a frame and furniture (hinges, handles, locksets) and can be made from a number of different materials.
To estimate the cost of a project without a specification is impossible and to enter into a contract without one is very short-sighted. Too many building contracts are entered into with vague information. The specification should form an integral part of the building contract. It is important to note that there is no such thing as a standard specification as no two structure are alike or use the same materials.
The format of the page and building process forms the basis of a specification. Each section and sub-section should be looked at separately and the information used to compile a specification for each particular trade or process.
