The Increasing Popularity of 3D modelling in Homebuilding

‘Keeping up with the Joneses’ is as important for homebuilders as it is for home buyers. Increasingly, homebuilders are using technology to work faster, more efficiently and not just keep up with homebuilding advances but make themselves just a little bit unique. For many firms, that entails moving from 2D drawings alone to incorporating 3D modelling in the design process. The trend of using 3D architectural modelling, ArchiCAD 3D modelling or Revit modelling services, as part of the BIM residential construction process, is on the up and up.

Not-so-obvious Benefits

One of the key advantages of using a 3D environment as part of the design process is the obvious one – in 3D, it is possible for everyone involved to visualise and comprehend what the design will look like on completion. With the introduction of BIM (Building Information Modelling) technology in the industry, further not-so-obvious benefits ensued, such as:

  • Improving communication and collaboration between customers, designers, architects, contractors, on-site labour teams and other stakeholders during the different design stages and construction phases
  • Enabling the identification and resolution of clashes or other potentially costly challenges
  • Modelling every component of the building project in detail, including walls, doors, studs, bolts and outlets with modern 3D modelling software tools, helping to develop an efficient and accurate design.
  • Facilitating accurate estimation of materials quantity, quality and sizes
  • Identifying and avoiding clashes between MEP (M&E), architectural and structural systems and components
  • Showing spatial details, finishes and textures to clients so that they can make modifications if required

Although, there are a number of benefits to using 3D modelling as part of the design workflow, some of them have several layers of benefits. For example, some of the clashes and challenges for homebuilders that can be identified through the use of 3D models are:

  • Any differences in dimensions between architectural drawings and engineered trusses
  • Potential problems with HVAC design, such as floor trusses and duct chases that are not aligned
  • Obstacles that may occur for supply and return ducts
  • Toilets and other drains directly above trusses
  • Roofing problems not seen in 2D that are obvious in 3D
Marketing Magic

Using 3D models to create 3D rendered images can have a significant impact on marketing. In addition to the look and feel of a home, potential buyers can view the materials and textures that can be used in their homes and make any changes that they want. By creating 3D models, it is possible to document and record utility lines for future facilities management processes and accurately represent lines of layout walls for carpenters, which can save costly common errors.

Smooth Operator

Utilising 3D modelling makes project execution smoother, as it becomes easier for contractors to complete construction according to a clear design and cut costs. A clear design helps contractors execute large homebuilding projects with:

  • Reduced or no field interferences
  • Reduced or no rework
  • Improved productivity
  • Reduced on-site confusion
  • Reduced change orders
  • Reduced extra expenses
  • Clear processes to keep to the projected time schedules
Interior Design Perks

A 3D model can showcase the furniture, wall paints, home accessories, designer ceilings and other interior features that can make a house feel like a dream home for future home buyers.

Data on Dimensions

A 3D model reflects the exact physical dimensions of spaces and the objects in the layout, helping homebuilders make adjustments to navigate through available space and modify room sizes, if required.

Building Services

Creating 3D models for the coordination of mechanical, electrical, plumbing/public health/hydraulic and fire protection systems has been invaluable on large homebuilding projects.

As with each advance in the AEC industry with regard to homebuilding, the popularity of 3D modelling seems well entrenched for the time being, and until something more advanced arrives, it seems here to stay. This means that it is essential for large homebuilders to find experienced and expert design support to provide them with accurate residential BIM services, 3D CAD modelling services, architectural construction drawings and other architectural CAD services. The right design support services will enable homebuilders to concentrate on other core tasks, secure in the knowledge that their 3D architectural modelling processes are well taken care of.

XS CAD has valuable experience providing architectural design drafting and 3D architectural modelling services for homebuilders, general contractors and design consultants. Our range of services for global firms across the world include architectural CAD services, architectural BIM services, ArchiCAD 3D modelling, Revit modelling services, architectural construction drawings and other 3D CAD modelling services. We offer retained teams when required, and we create these models, drawings and BIM services by using Revit, AutoCAD and BIM Collaborate Pro for cloud collaboration.
