How to Implement BIM: A Practical Guide for Consultants

Implementing Building Information Modeling (BIM) can significantly improve productivity, reduce errors, and streamline project coordination for consultants in the built environment. But successful implementation goes beyond just software—it requires careful planning, the right expertise, and a well-structured process.

Define Clear Objectives and Scope

Start by identifying your project’s BIM goals—whether it’s improving design accuracy, enhancing coordination, or meeting regulatory compliance. These goals should be documented in a BIM Execution Plan (BEP), which outlines what you hope to achieve and how you intend to get there.

Develop a BIM Execution Plan (BEP)

The BEP serves as the roadmap for your BIM implementation. It defines key deliverables, model uses, coordination processes, and compliance standards such as IFC and ISO 19650. It should also include the project's LOD expectations and the roles of different stakeholders.

Rather than starting from scratch, consultants may choose to adapt a ready-made BEP from experienced BIM service providers.

Choose the Right BIM Software

Your choice of software depends on your discipline and role in the project:

• Architects may use Revit or ArchiCAD
• Structural engineers might prefer Tekla Structures or SAP2000
• MEP consultants often choose OpenBuildings Designer or Revit MEP

Make sure your tools support OpenBIM standards for better collaboration across disciplines.

Invest in Training and Skills Development

Having the right tools means little without the skills to use them. Invest in structured training programs for your team. For new users, basic courses in BIM authoring tools such as Revit or OpenBuildings can accelerate onboarding. Where applicable, upskilling to meet ISO 19650 standards is recommended for consultants handling complex or international projects.

Establish Collaborative Workflows

Collaboration is at the core of BIM. Set up workflows that allow consultants, subcontractors, and QPs to share and review models in a single environment. Cloud-based Common Data Environments (CDEs) like Autodesk Construction Cloud or Bentley ProjectWise support version control, federated models, and transparent model history.

In Singapore, BIM models must often be reviewed and signed off by a Qualified Person before submission to BCA via CORENETX. A proper CDE setup enables timely reviews, clash checks, and streamlined coordination among all parties involved.

Work with BIM-Ready Subcontractors

Partnering with subcontractors who understand BIM workflows minimizes rework and miscommunication. When everyone is aligned on modeling protocols and coordination expectations from the beginning, issues can be identified and resolved early.

Integrate BIM into Existing Processes

Don’t treat BIM as a separate process. Instead, weave it into your current project management, cost tracking, and quality control systems. This ensures smoother adoption and maximizes the return on your digital investment.

Ensure Regulatory and Technical Compliance

Adherence to global standards like ISO 19650, and model formats like IFC, is essential. Local authorities may also enforce specific guidelines—for example, Singapore’s CORENETX system requires IFC submissions in a standardized structure.

To meet these requirements, consultants must ensure their teams are trained to navigate regulatory tools and workflows. For Singapore-based professionals, consider IFC training for OpenBuildings to stay compliant.

Start Small, Then Scale

Kick off with a pilot project to test your processes and tools. This allows you to gather feedback, refine your workflows, and build internal confidence before applying BIM across larger and more complex projects.

Collaborating with a BIM consultant can help accelerate this process. Their infrastructure, standards, and templates can serve as a foundation while you build up internal capability.

Conclusion

BIM implementation isn’t just about adopting new software—it’s about transforming the way projects are delivered. By taking a structured, standards-compliant approach, consultants can deliver better outcomes, win more projects, and play a leading role in digitalizing the AEC industry.
