Unlocking the Power of BIM

Building Information Modelling (BIM), as a digital representation of the physical and functional characteristics of a building, has revolutionised the architecture, engineering, and construction (AEC) industry by providing a collaborative and information-rich platform for designing, constructing, and managing buildings and infrastructure.

In the past couple of years the adoption of BIM by specifiers has skyrocketed with an estimated 70% of specifiers now demanding high quality BIM objects for incorporation into their project. Adoption rates have now risen for 11% in 2011 to 88% in 2023 according to a recent white paper published by NBS.

Some primary reasons for moving to BIM that could be discussed with your team include: Mandatory requirements for new projects, efficiency in project documentation, coordination troubleshooting and the ability to work with others who already use BIM looking toward the future of the industry. Check out this really hand visualisation tool from the recent NBS BIM white paper.

  1. Improved Collaboration and Communication:
    • BIM facilitates seamless collaboration among project stakeholders, including architects, engineers, contractors, and clients. Real-time data sharing and centralized information in a Common Data Environment (CDE) reduce communication gaps and enhance team coordination especially between the specifier and the Manufacture.
  1. Enhanced Design Visualization:
    • BIM enables architects to create 3D models that provide a realistic representation of the proposed design. Visualizations help architects and clients better understand the project, fostering effective decision-making and reducing misunderstandings.
  1. Efficient Design Iterations:
    • BIM allows architects to explore various design options quickly and efficiently.
    • Parametric modelling enables easy adjustments, fostering iterative design processes and allowing architects to refine their concepts with minimal effort and in a timely manner.
    • Architects can leverage BIM to access and analyse a wealth of data related to the project, such as material specifications, costs, and sustainability metrics.
      Informed decision-making is supported by accurate and up-to-date information, leading to more efficient and well-informed design choices.
  1. Streamlined Documentation:
    • BIM automates the generation of construction documents, reducing the likelihood of errors and inconsistencies. Automatic updates ensure that all project documentation reflects the latest design changes, enhancing the overall accuracy of drawings and specifications.
    • The Golden Thread concept aligns closely with the principles of BIM. With the Recent changes to the Building Safety Act using Bim enables for the concise documentation of the design decision, material specified and specific detail to be recorded in a consistent and easily accessible manor. This contributes to ensuring transparent record evaluation and aids in compliance with regulatory requirements. With the introduction of the accountable individual, using BIM can provide additional peace of mind when for the specifier when checking conformance of the solution to their regulatory requirements.
  1. Clash Detection and Conflict Resolution:
    • BIM includes clash detection tools that help identify potential conflicts and clashes among different building systems and components. Early detection of clashes allows architects to resolve issues before construction, minimizing costly rework and delays.
  1. Enhanced Cost Estimation and Budgeting:
    • BIM facilitates the integration of cost-related information, enabling architects to generate accurate cost estimates and budgets during the design phase. Improved cost visibility helps in making informed decisions regarding materials and design choices, aligning the project with budget constraints.
  1. Sustainable Design and Analysis:
    • BIM tools support architects in assessing the environmental impact of design decisions.
      Energy analysis, daylighting simulations, and life cycle assessments empower architects to create more sustainable and eco-friendly designs. When designing a BREEAM project the data integration that BIM offers enables a much easier review and understanding of the potential BREEAM statues your projects may achieve as well as making it easier to identify ergonomic design changes that can be made to help you achieve your desired BREEAM status.
  1. Continuity Across Project Lifecycle:
    • BIM ensures continuity of information from the design phase through construction and facility management. Architects can contribute to the creation of a comprehensive digital twin, enabling efficient building maintenance and future renovations.
  • Project Specific Requirements:
    • ISO 19650 forms part of the UK BIM Framework, the overarching approach to implementing BIM in the UK. Conforming to ISO 19650 means that you are aligned to the UK information management mandate. Public Sector projects require all relevant manufacture products to conform and support the application of their systems with BIM.

There are a number of standards that define BIM information structures and processes internationally.

Information structures:

  • ISO 16739-1:2018 – ‘Industry Foundation Classes (IFC) for data sharing in the construction and facility management industries — Part 1: Data schema’.
  • ISO 12006-2:2015 – ‘Building construction – Organization of information about construction works – Part 2: Framework for classification’. The UK National Foreword of this standard lists Uniclass 2015 as the classification system for UK BIM.
  • ISO 23386:2020 – ‘Building information modelling and other digital processes used in construction — Methodology to describe, author and maintain properties in interconnected data dictionaries’. At NBS, we follow this framework when modelling information structures with manufacturers in the NBS Source platform.


  • UK BIM Framework – the ISO 19650 series of standards defines the BIM process internationally. These had their basis in the UK PAS 1192 series of standards. The UK BIM Framework website has further information on these standards, and extensive free-to-use guidance resources. 

Early engagement with a manufacturer can play a crucial role in supporting the specification process for all project stakeholders. By chOosing a manufacturer that has BIM-ready content for their products, a specifier can ensure they have accurate and up to date product data within this building design.

Polyroof’s Specification Team and technical team are on hand to assist the specification process throughout all design stages. Our highly trained teams will provide you with a complete solution for your projects which includes a full NBS Uniclass specification with the relevant BIM models. By correct and early engagement you can help take the pain out of the specification process.
