What do specifications include

Proprietary specs are used when you need to use a single type of product for any kind of installation. These are the least common of the three types of construction specifications, but they are for jobs involving existing equipment and already completed installations.

When the owner or client wants to be consistent with their materials or just prefers a specific type of material, use proprietary specs. Contractors use proprietary specs when their section of the project is dependent upon the performance of a specific product.

Architects and engineers tend to try and avoid proprietary specs because it can lead to promoting a specific manufacturer. Favoring a manufacturer can discourage competition during the bid phase of the project, which may increase the total cost of the project. Architects and engineers will give the contractor a list of reliable suppliers to choose from to stop this.

Specification: A detailed description of the dimensions, construction, workmanship, materials etc. Shorter Oxford English Dictionary. What is specification? Let's look at what we mean when we talk about a specification; here is an official definition: "Specification: A detailed description of the dimensions, construction, workmanship, materials etc.

Early specification - lessons learned. It can reference the quality and standards which should be applied. Installation, testing and handover requirements can be identified. Classification within the specification can be used to support handover and asset management. Lastly, when provided in advance, a solid set of specs can lead to more accurate bids, resulting in fewer cost overruns.

Generally, there are three different types of construction specifications found in contracts: prescriptive specifications, performance specifications, and proprietary specifications. Prescriptive specifications provide step-by-step details and instructions on how the types of materials to be used and the desired installation methods.

However, these types of specs can be split into three subcategories. Performance specifications will provide all of the operations requirements to complete a project. Instead of giving detailed instructions on how to achieve the desired final product, performance specs will describe the anticipated result. This leaves a broad amount of discretion to decide how to perform, as long as the desired outcome is achieved.

Accordingly, performance specs will invariably include extensive testing provisions to ensure that the project meets all the operational requirements. These third types of specifications are the rarest of the breed.

They are used when a specific type of product or material is required for installation. Typically, proprietary specs are used when doing renovations to an existing structure, and the client needs to match the improvements to the completed portion.

That is, unless there are glaring errors or omissions that should have been caught in the first place. Thus, when a construction defect arises, the party who will ultimately be held liable depends on what type of specification the sub was working from. The Spearin Doctrine. Performance specs allocate liability to the party performing the work because they have free rein to decide how the end result is achieved. Conversely, if the specs are prescriptive, the party who issued the specifications may be liable.

Prescriptive specs provide play-by-play instructions to perform. I am a junior college student working on a presentation looking for a simple explanation that anyone could understand, possibly with some examples.
