Your specification partner

MIDDAS understand that most architects and specifiers require BIM objects and want easy access to manufacturers’ product information.  We have partnered with NBS Source to provide you with our product data in the format needed for your specification.

Our high-quality product families are available in both 2D (CAD) or 3D (Revit) models, ready for adding to your project specification.

We work alongside specifiers to facilitate the process, ensuring all product information is accurate for improved project quality.

We engineer cost-effective solutions, modelled in either a 2D CAD or 3D BIM environment to ‘design right’ from the outset.

We work with project design teams, architects and specifiers from some of the industry’s top players, including Ridge, Sheppard Robson and HOK.

Specification FAQs
  • What is a specification and why is it important for construction?

    A specification is a type of technical standard that gives a detailed description of all dimensions, construction, workmanship and materials of the required work to be done for a construction project. The specification is required during the design phase and defines (in words) what cannot be explained on a 2D drawing or 3D model. It forms part of the contract documentation and is typically prepared by an architect, architectural technologist or a construction project specifier.

    The specification is an integral part of the Building Information Model (BIM) and remains a key element of the construction process because it supports the Golden Thread of information. It also provides clear instructions on the intent of a construction project, along with building performance requirements.

  • What information is included within a specification?

    In construction projects, the specification document covers a comprehensive set of information, including:

    • The establishment of a site.
    • The type of contract.
    • Requirements for performance, systems and product quality.
    • Any applicable building standards and how they are executed.
    • Any specific products that the specifier wants to use.
    • Requirements for installation, testing and handover.
  • How do you write a good specification?

    A specification is a living document that can be updated with information throughout the design phase and should be written in the earliest stages of a project lifecycle as the best practice. Early client requirements and high-level building performance should be captured so it can evolve as the design progresses, into choices about the systems, products and manufacturers needed.

    Specification platforms such as NBS Chorus provide easy-to-use template clauses for a wide range of system types which are kept up to date with references, allowing specifiers to issue published versions at key project stages. A good specification will follow the key principles as outlined by NBS – the 7 C’s of specification:

    CLEAR – use plain language and short phrases to avoid ambiguity

    CONCISE – exclude irrelevant information to keep the specification ‘project specific’

    CORRECT – clarify requirements and outcomes, referencing all relevant BS, EN and/or ISO standards as necessary

    COMPLETE – use an appropriate depths of information and do not specify differently for contractors or manufacturers

    COMPREHENSIVE – define everything once, in the right place, and use cross-references to avoid repetition or conflicts

    CONSISTENT – use a standard structure, terminology and style throughout so it is easy to navigate

    COORDINATED – ensure drawing references are updated to match model annotations and other contract documentation

  • Where can I find examples of building specifications?

    Sample templates of construction specifications can be downloaded from NBS Chorus which will use the standard structure. The content of your specification will of course need to be specific to your project, but the available samples demonstrate the level of quality, structure, and outputs necessary to create a consistent database of information.

  • How do I add MIDDAS products to my specification?

    All MIDDAS products are listed on NBS Source and anyone with an NBS Chorus subscription can easily specify them.  You can access our product data directly from the product buckets listed above.

    Product data can also be copied using the convenient ‘Add to Spec’ buttons on our individual product pages. Simply navigate to the product you want to specify, scroll down to the Technical Details section, and click the purple NBS button.

  • Do MIDDAS write specifications for clients?

    Currently, we do not write our own specifications or tenders. We do, however, support clients with their own project briefs and can help contractors understand the building requirements for their site.
