The written document defining the quality standards, materials, and methods required for all work on a project.
A specifications document is the formal written technical document that describes the required materials, products, standards, and quality of workmanship for each element of a construction project. Construction specifications are organized using CSI MasterFormat divisions and sections. They supplement the drawings by providing information that cannot be shown graphically.
The specifications document, or project manual, is where bidding instructions, general conditions, and technical sections live, so it sets both the commercial terms and the quality bar for the entire bid. Estimators rely on it to assign scope to subs, identify owner-furnished items, and catch requirements like allowances, alternates, and unit prices that must appear on the bid form.
Before sending invitations to bid, the estimator splits the specifications document by MasterFormat division and emails each trade only the sections that apply, ensuring the electrical sub sees Division 26 while the concrete sub gets Division 03.
