Specification For Construction Designing Buildings Wiki Pdf Pdf Performance (open) specifications describe the result that is required from particular items and leave it to the contractor or supplier to satisfy that requirement. in effect it requires the contractor or supplier to complete the design. In international construction projects, the distinction between design (or prescriptive) and performance specifications plays a pivotal role in shaping contractual obligations and risk allocation.
Performance Specification Pdf As a building regime that is performance based rather than prescriptive. an adjunct to this regime, most successfully used for complex buildings, is a ‘performance’ specification – where performa. ce requirements are written into the specifications rath. These performance options are conceived to achieve higher than code minimum design requirements. a design approach that provides designers with tools to achieve specific performance objectives such that the performance of a structure can be reliably predicted. Nfpa 5000 sets forth both performance and prescriptive options for design and construction. the various prescriptive building, fire, and life safety codes all contain provisions for what is known as “alternative methods and materials” or “equivalency.”. This guide breaks down every major construction specification type, from prescriptive and performance to open and closed, so you know what each one does and when to use it.

For example, a prescriptive specification would tell the contractor exactly what size motor we want to drive the vacuum cleaner. in contrast, a performance specification would tell them what kind of suction we want at the other end. In practice, the distinction between design and performance specifications sometimes becomes muddled. the purpose of this article is to provide some guidance for drafting and recognizing performance specifications that will shift the risk for design to the design builder. What is a performance specification? this is a specification where the designer (architect engineer) sets the criteria for the contractor to deliver a package of work within a set of parameters.
