Specifications in the UK are part of the contract documents that accompany and govern the construction of a building. Data systems that can process, store and transfer information about food and food products need formal specifications for the representations of data about food and food products in order to operate effectively and efficiently. [1] A specification is often a type of technical standard. Development of formal specifications for food and drug data with the necessary and sufficient clarity and precision for use specifically by digital computing systems have begun to emerge from some government agencies and standards organizations: the United States Food and Drug Administration has published specifications for a "Structured Product Label" which drug manufacturers must by mandate use to submit electronically the information on a drug label. Sometimes a guide or a standard operating procedure is available to help write and format a good specification. Specifications are an integral part of Building Information Modeling and cover the non-geometric requirements. Voluntary standards may become mandatory if adopted by a government or business contract. This is a consensus document that is jointly sponsored by two professional organizations: Construction Specifications Canada and Construction Specifications Institute based in the United States and updated every two years. For example, Mac OS X has many components that prefer or require only decomposed characters (thus decomposed-only Unicode encoded with UTF-8 is also known as "UTF8-MAC"). The people who use the item (engineers, trade unions, etc.) The word specification is broadly defined as "to state explicitly or in detail" or "to be specific". [20][21], Specifications and other standards can be externally imposed as discussed above, but also internal manufacturing and quality specifications. The standard AIA (American Institute of Architects) and EJCDC (Engineering Joint Contract Documents Committee) states that the drawings and specifications are complementary, together providing the information required for a complete facility. Specification writers frequently meet with manufacturers of building materials who seek to have their products specified on upcoming construction projects so that contractors can include their products in the estimates leading to their proposals. Although many Architects find the rather voluminous commercial style of specifications too lengthy for most residential projects and therefore either produce more abbreviated specifications of their own or use ArCHspec (which was specifically created for residential projects). [7][8][9] A specification might include: Specifications in North America form part of the contract documents that accompany and govern the construction of building and infrastructure projects. ), trade associations, corporations, and others. The original listing of specification divisions was based on the time sequence of construction, working from exterior to interior, and this logic is still somewhat followed as new materials and systems make their way into the construction process. Popular Building & Construction Standards. Specification writers are either employees of or sub-contractors to architects, engineers, or construction management companies. Pharmaceutical products can usually be tested and qualified by various Pharmacopoeia. A design or product specification describes the features of the solutions for the Requirement Specification, referring to either a designed solution or final produced solution. The guiding master document of names and numbers is the latest edition of MasterFormat. It describes what the system should do, not (necessarily) how the system should do it. Guide to identifying criteria for specifying a service offering, Date of last effective revision and revision designation, Table of Contents (TOC), if the document is long. Specifications describe the quality and performance of building materials, using code citations and published standards, whereas the drawings or building information model (BIM) illustrates quantity and location of materials. The standard listing of construction specifications falls into 50 Divisions, or broad categories of work types and work results involved in construction. C926-20b: Standard Specification for Application of Portland Cement-Based Plaster. However errors due to file name encoding incompatibilities have always existed, due to a lack of minimum set of common specification between software hoped to be inter-operable between various file system drivers, operating systems, network protocols, and thousands of software packages. [2] It is a common early part of engineering design and product development processes, in many fields. ARCAT Specs are complete, accurate, and in the CSI 3-part and the Canadian CSC formats for building and construction professionals. The MasterFormat and section format[17] system can be successfully applied to residential, commercial, civil, and industrial construction. Provisions for rejection, reinspection, rehearing, corrective measures. In February 2015, ArCHspec went live, from ArCH (Architects Creating Homes), a nationwide American professional society of Architects whose purpose is to improve residential architecture. They are created from previous project specifications, in-house documents or master specifications such as the National Building Specification (NBS). UK project specification types fall into two main categories prescriptive and performance. An "in-service" or "maintained as" specification, specifies the conditions of a system or object after years of operation, including the effects of wear and maintenance (configuration changes). This is a consensus document that is jointly … Given such a specification, it is possible to use formal verification techniques to demonstrate that a candidate system design is correct with respect to that specification. Validation of suitability is necessary. Many public agencies, such as the Naval Facilities Command (NAVFAC) state that the specifications overrule the drawings. At the present time, much of the information and regulations concerning food and food products remain in a form which makes it difficult to apply automated information processing, storage and transmission methods and techniques. A data sheet describes the technical characteristics of an item or product, often published by a manufacturer to help people choose or use the products. An item might be verified to comply with a specification or stamped with a specification number: this does not, by itself, indicate that the item is fit for other, non-validated uses. The National Building Specification is owned by the Royal Institute of British Architects (RIBA) through their commercial group RIBA Enterprises (RIBAe). In one specific instance, the combination of OS X errors handling composed characters, and the samba file- and printer-sharing software (which replaces decomposed letters with composed ones when copying file names), has led to confusing and data-destroying interoperability problems.[27][28]. It can be informal, in which case it can be considered as a user manual from a developer point of view, or formal, in which case it has a definite meaning defined in mathematical or programmatic terms. While there is a tendency to believe that "specifications overrule drawings" in the event of discrepancies between the text document and the drawings, the actual intent must be made explicit in the contract between the Owner and the Contractor. While North American specifications are usually restricted to broad descriptions of the work, European ones and Civil work can include actual work quantities, including such things as area of drywall to be built in square meters, like a bill of materials. The guiding master document of names and numbers is the latest edition of MasterFormat. E1186-17: Standard Practices for Air Leakage Site Detection in Building Envelopes and Air Barrier Systems. The following British standards apply to specifications: A design/product specification does not necessarily prove a product to be correct or useful in every context. In engineering, manufacturing, and business, it is vital for suppliers, purchasers, and users of materials, products, or services to understand and agree upon all requirements.[3]. ASTM International and the global construction industry have long partnered to promote progress and innovation in building homes, offices, and other facilities worldwide. ArCHspec was created specifically for use by Licensed Architects while designing SFR (Single Family Residential) architectural projects. A specification may refer to a standard which is often referenced by a contract or procurement document, or an otherwise agreed upon set of requirements (though still often used in the singular).
