Technological advances versus the standard – it becomes an age-old dilemma. Which one is more preferable? Well, regarding the BIM design versus traditional 2D design debate, even traditionalists are voting for that evident benefits associated with BIM design using architectural CAD services. As several layers of BIM design benefits are unveiled, the way in which forward becomes ever clearer. Determining how and why BIM design can be a more desirable methodology might be vital to increased profits from the AEC (architecture, engineering and construction) industry.
Firstly, what exactly do we mean by BIM design?
An intelligent 3D model-based process, Building Information Modelling, or BIM, provides insight and tools to AEC professionals to be able to efficiently design buildings and infrastructure, while adding data (information) towards the models to be used downstream. The BIM process requires the creation, evolution and monitoring of digital representations on the physical and functional elements of building design. This process is enabled throughout the generation of BIM files containing a lot of data that is viewed, changed or communicated to every one stakeholders within a project. BIM software can often design water, refuse, electricity, gas, communication utilities together with roads, bridges, tunnels, etc. The BIM process will not be restricted to generating just 3D models, nonetheless it may provide more dimensions, for example 4D (time), 5D (cost) and 6D (as-built operation). Since the BIM process covers a real wide range of functions, its benefits are numerous.
Benefits of BIM Design
Improved Quality – At any given time in the design process, BIM enables a large degree of flexibility. The design could be thoroughly explored and changed. Time for coordination and manual checking are minimised, allowing other tasks for being completed.
Increased Speed – Design and documentation might be performed simultaneously with all the BIM process. Therefore, schedules, diagrams, drawings, estimations, value engineering, planning along with other forms of communication are generated whilst the design process is ongoing, not waste time.
Reduced Cost – Smaller technical teams works with work previously performed by larger teams, ultimately causing reduced miscommunication and fewer cost. Because of greater document quality and even more effective planning, time and cash are saved on processes.
And now, what’s 2D design?
Design elements in 2D design, since its title suggests, are simply just portrayed by 50 percent dimensions, length. Typical documents of 2D design consist on the floor plan, the vista and the section.
The floor plan consists with the building outline, rooms, structural elements (walls, etc.), furniture, dimensions, altitudes, uncovered spaces, openings (doors, windows), all attracted to scale so when they would be observed from above. Fixtures, like sinks, water heaters, furnaces, etc., can be included, together with notes for construction. Floor plans have to make views and sections.
A section is often a 2D drawing products a building would seem as if it absolutely was cut down the guts vertically to show the interior view. It can show steps, doors, windows, etc. Section drawings and floor plans are from the same scale.
A view relies on vantage point. Typically, you’ll find front views, back views, nearly everywhere views. A view will include things like floor section lines, visible structural elements, including doors, windows, balconies, walls, furniture and also plants.
Benefits of 2D Design
When design moved from traditional paper drawings to digital 2D, sketches and drawings became easier and faster to build and share. Working on a worldwide scale became increasingly easier and much more effective.
Drawbacks of 2D Design
Design in 2D is bound due to its nature, and drawings cannot fully explore the vast range of design options properly. Limited information or data is usually included in 2D design.
So, how can BIM design look when compared with 2D design? Some with the key places where BIM design scores over 2D design are:
There can be a great amount of knowledge available, for instance aerial imagery, digital elevations and laser scans of existing structures, with BIM design that is usually compiled and shared inside a model, unlike most things that 2D drawings convey.
Working with a shared model means there may be less rework and duplication of drawings. With more information over a 2D drawing, each discipline can annotate and connect towards the project in BIM design. With faster tools, BIM design enables a database to become hosted that assists stakeholders know when you’ll find changes or updates, minimising rework.
With an electronic digital workflow, more functions make collaboration easier with BIM design as compared to 2D design. Many of these functions are delivered from the cloud, BIM 360/Collaboration for Revit (C4R) being one on the solutions. Input on project changes may be reviewed and noted by all stakeholders, increasing collaboration.
Views of the project in several light conditions and calculating a building’s energy performance are enabled by simulation tools in BIM design. More analysis and modelling may be carried out for effective project design. Renders are produced easily in 3D for marketing purposes and gain approvals.
Improved Conflict Resolution
Elements from different disciplines can clash at some time, for example an electrical conduit running right into a duct or maybe a beam. With BIM design, clashes are identified in an early stage, reducing on-site clashes. This design method can also help ensure prefabricated components fit correctly into previously designed spaces.
BIM design enables particles design to become coordinated and within the right sequence, with the appropriate materials and helpful greater efficiency.
As the BIM design process involves sharing plans, sections, elevations and reports and updates using the entire project team, the general design process becomes faster as compared to a 2D design method.
The BIM design model is linked with a large database, which may be hosted within the cloud. Using BIM 360 software enables this information to become accessed on any device, from any location.
More Effective Communication
Using 2D design, many separate documents are expected to get a complete view with the project. With BIM design, all documents are within a single view, allowing better communication.
