In February 2015, ArCHspec left live from ArCH (Architects Creating Homes), a national professional company of American architects that aims to improve residential architecture. ArCHspec has been specially designed for use by licensed architects in the design of SFR (Single Family Residential) architecture projects. Unlike the CSI (50-Division Commercial Specifications), arCHspec uses the 16 most recognizable traditional divisions, as well as a Division 0 (Scope – Bid Forms) and a Division 17 (low voltage). Many architects have not yet submitted specifications for residential designs, which is one of the reasons why ArCHspec was created: fill a gap in the industry with more compact specifications for housing use. Shorter form specifications, suitable for private use, are also available via Arcom and follow the 50 division format that was introduced in the United States and Canada starting in 2004. The 16-division format is no longer considered standard and is not supported by CSI, cSC or any of the subscription specification services, data repositories, product management systems and most government authorities. The standard list of construction specifications is divided into 50 divisions or broad categories of work types and construction-related work outcomes. Subdivisions are subdivided into sections that each address a particular type of material (concrete) or a work product (steel door) of construction work. Depending on the result of the work, a particular material can be covered in several places: stainless steel (e.g.B.) can be covered as sheet metal material used in 07-division flashers and sheets; it can be part of a final product, for example. B of a division 05 handrail; or may be part of the building material that is processed in department 08. The initial list of specification divisions was based on construction time, which worked from the outside to the inside, and this logic is still somewhat followed, as new materials and systems find their place in the construction process.
A design/product specification does not necessarily prove that a product is correct or useful in all contexts. An item can be checked to meet a specification or stamped with a specification number: this does not mean that the item is suitable for other unredified uses. People who use the article (engineers, unions, etc.) or the article (building rules, government, industry, etc.) have a responsibility to take into account the choice of available specifications, to indicate the correct specifications, to impose compliance and to use the article correctly. Qualification validation is required. The opposite of explicit specifications is a procedure for managing observations that comply with specifications a. The United States Food and Drug Administration has issued a non-binding recommendation that specifically addresses this point.  Specifications and other standards may be imposed outside, as described above, but also internal manufacturing and quality specifications.
