What is open proprietary specification?
What is open proprietary specification?
An open proprietary specification describes a single product or system but allows the bidder to suggest an alternate or substitute product. The correct use of alternate, option, and substitution is important when writing proprietary specifications as each has a fundamentally different meaning.
What are the 3 types of construction specifications?
In every construction project, there are three types of construction specifications. The three types of construction specifications are prescriptive, performance, and proprietary.
What is a proprietary specification in construction?
Proprietary Specifications demand that only one specific product be used for a given installation. It is commonly utilized if the portion of a project requires a certain performance that only one product can achieve. This could ultimately drive up project costs. By default, closed specifications are proprietary.
What is the difference between a design specification and a performance specification?
Under the Spearin doctrine, a design specification sets forth the detail, manner, and materials to be used, as opposed to a performance specification which describes the desired end result, but gives the contractor discretion to decide how best to complete the work.
What are the two types of specification?

- General Specifications.
- Detailed Specifications.

When do you use proprietary specifications in construction?
Proprietary specifications are often used in cases where there is existing equipment or installations already on site. In these cases the owner may want to maintain consistency of materials or possibly simply prefers a specific type of product.
How are the four types of specifications determined?
Deciding among the four types of specifications —descriptive, performance, reference standard, and proprietary—and choosing how the specification is going to be written is only the first of many design decisions engineers make when starting to edit what will become a project specification, especially when specifying proprietary systems or products.
What makes a nonrestrictive specification an open specification?
Nonrestrictive specifications (commonly referred to as an “open” specification) are written in such a manner as to not limit competition, directly or indirectly, to any one specific concern. An “open” specification allows products of any manufacturer to be used if the product meets the specifiedrequirements.
