BIM for builders

What is BIM?
BIM (Building information Modeling) is a process used to design, store, review & deliver project information and documentation.

Why should I use BIM solutions?

  • BIM creates a smoother build process by allowing the builder to review the project in full detail prior to build start.
  • BIM solutions can highlight potential problems before they cost time and money on-site.
  • The BIM process creates confidence by co-ordinating 3D models from multiple suppliers (steel, frame & truss, HVAC etc.)
  • BIM generated 3D models online anytime. Mobile or PC friendly.
  • BIM co-ordination can help reduce on the job surprises.

BIM in the Architectural Design Stage

Accurate Site Mesh Modelling
Realistic Architectural Model
Real-time design adjustments
Project estimating

Benefits

  • Daylight & Height Restrictions Compliance, Foundation Level accuracy, cut & fill excavation volumes, retaining wall heights & profiles.
  • True to life representation allowing clients to view and understand proposed designs, in full detail, in any number of visual formats. E.g. images, plans, panorama tours, online 3D models, virtual reality.
  • Providing the client the opportunity to review various design options that ensure they fully understand the design choices being made, reducing onsite changes that are time consuming and costly to undertake during the construction process.
  • Using the BIM model to generate preliminary project costings provides the client with an initial estimate of build costs. Reducing the possibility of concept design exceeding clients budget or cost surprises during the build.

BIM in the Structural Design Stage

Full Structural Modelling
Design Collaboration
Structural Overview
Consultation

Benefits

  • The ability to fully model the building’s structural elements enables structural solutions to be developed in the design office, well before they cause headaches and additional costs onsite during the construction stage.
  • A BIM model can be shared in various digital formats which enables external designers (Engineering, steel, HVAC, electrical etc) to all utilise the same BIM model, reducing errors that come about from incorrect interpretations of 2D plans. E.g. mid floor plumbing vs steel beam.
  • While structural solutions are created individually throughout the building, the BIM model allows a wider overview to ensure all solutions are working together well. Elements clashes and overlaps can be seen clearly and resolved. E.g. Steel beam vs roofing iron.
  • The ability to share the BIM model on the web, or showcase it in VR, creates the opportunity to engage directly with builders during the structural design stage. This feedback can help redefine the BIM model to provide further efficiencies during construction.
