A work result is based on traditional construction practices and reflects a component or sub-system of a project that is generally designed, built, and maintained as a segment of the work. For example, there is no heading titled simply ‘sheet metal,' which is a type of product. Instead, sheet metal is found in specifications describing a work result, such as ‘flashing,' which could include fasteners, sealants, and other materials as well as the fabrication or installation of sheet metal. Sheet metal could also be found in another section of the specifications where it might be used to create ducts in a work result called ‘air distribution.' By employing a standard system of numbers and titles with which to order work results, MasterFormat is used for organizing project manuals for bidding and contract requirements, specifications, relating drawing notations to specifications, product information, detailed cost information, and building operations and maintenance functions.

Construction projects use many different kinds of delivery methods, products, and installation methods, but one thing is common to all-the need for effective teamwork by the many parties involved to ensure the correct and timely completion of work. Standardizing the presentation of such information, therefore, improves communication among all parties involved. This helps the project team deliver structures to owners according to their requirements, timelines, and budgets.

While MasterFormat addresses the practices of the many disciplines within the architecture and engineering professions, its divisions are not intended to establish design disciplines, despite the similarity between some MasterFormat division titles and traditional discipline nomenclature. Again, its organization is structured around a work result and is independent of whether a process engineer designs a facility's HVAC, or architect designs site drainage.

Nor do MasterFormat divisions establish trade jurisdictions. Assignment of work into bid and contract packages is defined by the building owner or by the general contractor-not by the divisions and sections of the project manual. For example, all concrete work may be specified in Division 03, but responsibility for it may be assigned to several contractors or subcontractors depending upon whether it is for site work, building foundations, superstructure, or equipment pads.

It is important to reiterate that MasterFormat is not structured around product classifications. As in the sheet metal example above, products are organized by work result. Asphalt, for instance, is a material that can be used in roofing, waterproofing, pavement, to protect against dissimilar metal contact, and other work results. Galvanized pipe, too, is found in many sections because it is a material that can be used in utilities, handrails, plumbing, electrical conduit, and other types of work results.
