Challenges Faced by Architects Still Working Without BIM

Legacy processes or tools cannot support architects or architectural firms. 2D drawings with limited accuracy and visualization hamper client communication and slow down Turn Around Time (TAT). Without BIM, architects face limitations, such as inefficient processes, communication silos, and design inaccuracies.

Limitations in collaboration

Fragmented collaboration between architects, engineers, and other participants leads to communication inefficiencies and communication gaps.

Manual documentation

Relying on manual drafting and documentation is error-prone and time-consuming, leading to inaccuracies and lower productivity.

Design coordination problems

Coordinating design modifications and updates across multiple drawings increases the risk of ambiguities and risks during construction.

Visualization difficulties

Without 3D models, architects have issues with visualization, leading to communication inefficiencies between teams and clients.

High error risks

Manual methods increase the chances of errors within design drawings and specifications, leading to rework, delays, and construction safety.

How BIM Benefits Architects in Making Design Decisions

Using BIM in the architectural design process supports architects in streamlining design, improving collaboration, and improving accuracy. BIM benefits architects with effective project management, greater visualization, innovation, and sustainability. BIM also augments productivity, enabling architects to make smarter decisions while achieving high-quality designs, as per client needs.

Visualization enhancements

BIM for architects is crucial as it provides architectural 3D modeling at a specific LOD with visualization and collaboration for architecture, structure, and MEP disciplines. Architects also use custom Revit families in various formats, including .rvt, .ifc, and .rte to improve dimensional and data accuracy within the 3D model.

BIM also offers architectural rendering and realistic animation in software like 3Ds Max, V-Ray, and SketchUp to help create high-and low-poly models with design coordination, lighting, materials, and texturing. Interactive 3D virtual tours with 3D walkthroughs and flyovers using lights and sound help bring greater project clarity to clients, architects, contractors, and owners.

Collaboration improvements

BIM facilitates collaboration between architects, contractors, and engineers over a centralized platform, such as BIM 360. Architects use a 3D BIM model containing multiple architectural, structural, and MEP elements for project-wide collaboration with multiple stakeholders. Decision making on the shared platform is quicker and in real time, leading to lower errors and seamless communication.

Iterative design

BIM software for architects has inherent capabilities to integrate various automation tools like scripts, Dynamo, and APIs. In fact, Revit enriched by Dynamo not only speeds up 3D modeling and 3D architectural design but also reduces design errors, leading to fewer iterations and reducing the need to perform repetitive tasks.

The design workflows supported by Revit families integrated within the Revit 3D BIM model improve component accuracy and data validity through in-depth information on specifications, dimensions, finishes, textures, and materials.

Clash detection

Clash detection and coordination among various disciplines, including architecture, structure, and MEP, is one of the most critical aspects of BIM for architects. Flagging and removing clashes between trades leads to lower rework and keeps delays at bay. Rework can undermine the reputation of architectural firms, as it reflects their ability to achieve precise and high-quality designs. In-depth coordination helps architects reduce labor, time, and resources. Furthermore, coordination augments productivity and morale.

Design sustainability

BIM tools like Revit help architects achieve design sustainability with tools to calculate energy efficiency, lighting, and the use of green building materials. Using a digital 3D model reinforced by parametric capabilities supports architectural firms in refining and optimizing design.

Exploring multiple design scenarios, evaluating environmental impact, and identifying improvement opportunities makes the project resource-efficient and environmentally friendly.

Revit supports the certification and documentation of sustainable building practices like LEED and AIA. Architects can use Revit to generate accurate drawings, reports, and schedules from 3D models. These can be used for sustainability assessments, regulatory compliance, and certification for enhanced project validity. Overall, Revit helps architects design aesthetic and environmentally sustainable buildings.

Quantification and cost estimation

BIM supports architects in pulling quantities and creating cost estimates from the 3D BIM model. This capability ensures architects evaluate the cost implications of design decisions, improve material use, and stay within budget limits.

Analysis and simulations

BIM tools offer architects with analysis and simulations for various design aspects, including energy efficiency, structural performance, HVAC systems, and daylighting. Architects can utilize these simulations to analyze design options, improve performance, and make data-driven decisions to enhance design quality.
