Article first time published onWhat is the example of specification?
The definition of a specification is a precise requirement, or a detailed description of workmanship, materials or processes. A mandate that only domestic plywood be used in the construction of your home is an example of a specification.
What are prescriptive specifications?
prescriptive specification. Specifications that describe not only the expected end result of construction, but also methods and materials that must be used to achieve the desired results. Also called proprietary specifications.
What are performance specifications?
A performance specification defines the functional requirements for the item, the environment in which it must operate, and interface and interchangeability characteristics.

What are manufacturing specifications?
A manufacturing specification contains all the information that is needed to make the product. It describes the stages of manufacture and the materials needed, using flowcharts, diagrams, notes and samples. … A manufacturing specification is done once the final product has been developed.
What are computer specifications?
Computer hardware specifications are technical descriptions of the computer’s components and capabilities. … Computer hardware specifications are technical descriptions of the computer’s components and capabilities. Processor speed, model and manufacturer. Processor speed is typically indicated in gigahertz (GHz).
What are engineering specifications?
Specifications. As previously mentioned, engineering specifications stipulate specific details for engineering, design, fabrication, and construction of a facility. Piping specifications in particular are used by numerous groups, whose goal it is to see a piping project through to completion.
Why are specifications important to materials and methods?
The specification provides clear instructions on project intent, performance and construction. It can reference the quality and standards which should be applied. Materials and manufacturers’ products can be clearly defined. Installation, testing and handover requirements can be identified.
What is the purpose of the specifications?
The purpose of a specification is to provide a description and statement of the requirements of a product, components of a product, the capability or performance of a product, and/or the service or work to be performed to create a product.
What are specifications and its importance?
PURPOSES OF SPECIFICATIONS : To describe the quality of different materials required for construction work. It enables the department, engineers, architect and contractor to define, procure and check the material’s quality as per specifications. To specify the quality of workmanship and method of doing the same.
What is material specification in construction?
Specifications describe the products, materials, and work required by a construction contract. They do not include cost, quantity, or drawn information, and so need to be read alongside other information such as quantities, schedules, and drawings.
What are specifications of a product?
A product spec is a blueprint that outlines the product you will be building, what it is going to look like, and its specific requirements and functions. It may also include the persona or user it is being made for. … A table or chart of specifications will make it clear where details can be found.
What are quality assurance specifications?
The QA Specification provides a framework for QA best practices and resources to enable the implementation of repeatable processes and optimize energy efficiency project risk assessment in order to give building owners and investors more confidence in projected savings and project engineering.
What is quality standard and quality specification?
Quality standards are defined as documents that provide requirements, specifications, guidelines, or characteristics that can be used consistently to ensure that materials, products, processes, and services are fit for their purpose.
What are specifications and constraints?
Constraints matter most to the producer whiles specification is a concern to the consumer in most cases. Constraint defines the specification of an object. To get your specification right then your constraints need to be right in the first place. Think of constraint as the mold to a ceramic cup.
What are proprietary specifications?
In general, proprietary specifications are descriptions of materials that either cite a specific brand name or are written so restrictively that only one vendor or manufacturer can supply the desired items.
What is a reference specification?
A non-proprietary specification based on accepted standards, or on requirements set by an acceptable authority, which describes products, materials, or pieces of equipment to be incorporated in a building project.
What is a full specification?
Also known as a full specification, it essentially identifies each and every item, right down to the spacing and number of screws required to fix plasterboard for example, as well as the size, type and material of the screw. This gives the client more certainty when the work is tendered and priced by the contractor.
