BIM for GCs: Why Subletting is the Key to Better Project Management?

Introduction

BIM has transformed the construction industry by bringing the greater collaboration, efficiency as well as the accuracy to the project execution. According to the Dodge Data & Analytics Smart Market Report, over 70% of the contractors reported an improved project outcomes due to the BIM implementation. However, for the General Contractors (GCs) managing the BIM workflows on their own can be a complex challenge. One of the key strategies that the GCs employ to optimize their processes is the BIM subletting, i.e., outsourcing the specific BIM-related tasks to the specialized service providers. When executed effectively, the BIM subletting enhances the efficiency, reduces the risks and ensures the seamless coordination across all stakeholders.

Understanding BIM Subletting

The BIM subletting involves delegating the various BIM-related tasks such as 3D modeling, clash detection, coordination as well as the shop drawings to the external consultants or the subcontractors. The goal is to leverage the specialized expertise while allowing the GCs to focus on their core project management responsibilities.

GCs often sublet BIM tasks to:

• The BIM consultants who handles the high-level coordination and execution.
• The MEP and structural subcontractors for the discipline-specific modeling and the coordination.
• The Offshore BIM service providers to achieve the cost efficiency while maintaining the high-quality outputs.

Why GCs Opt for BIM Subletting?

1. Cost Efficiency – Hiring an in-house BIM team can be expensive. According to the industry estimates, outsourcing the BIM services can dropdown the costs by 30-40% compared to managing a dedicated in-house team full-time.
2. Time Savings – Outsourcing the specific BIM tasks allows the GCs to focus on project execution hence reducing the bottlenecks and improving the workflow efficiency. The studies shows that the BIM adoption reduces the project delays by 20-25%.
3. Expertise and Quality – The External BIM specialists bring years of experience thereby ensuring that the models are accurate and comply with the latest industry standards. 90% of the BIM users reports in the better coordination and a decrease in errors.
4. Risk Mitigation – The BIM subletting reduces the risk of the costly errors and project delays by improving the clash detection and coordination. According to the National Institute of Building Sciences, the clash detection using the BIM can lead to a 5-10% cutback in the project costs.
5. Scalability – GCs can scale the BIM resources up or down based on the project requirements without any long-term commitments.

Key Considerations for Effective BIM Subletting

For BIM subletting to be successful, the GCs must adopt a strategic approach:

1. Define Scope and Deliverables Clearly

Clear documentation of the scope, roles and even the responsibilities is essential to avoid any sort of conflicts. The GCs must outline their expectations regarding the BIM execution plans (BEPs), the Level of Development (LOD) as well as the coordination requirements.

2. Choose the Right BIM Partner

Selecting a BIM Services Provider with the relevant industry experience, software expertise and also with a proven track record is crucial. The GCs should assess the provider’s portfolio thoroughly and also browse their client testimonials before making any sort of decision.

3. Establish Strong Communication and Collaboration

The successful BIM implementation requires seamless coordination between the GC, subcontractors and the BIM service providers. Utilizing the Common Data Environments (CDEs) as well as the real-time collaboration platforms like Autodesk BIM 360 or Trimble Connect ensures the smooth information exchange.

4. Ensure Data Security and Compliance

When outsourcing the BIM tasks, the GCs must ensure that all the data security measures are in place. The compliance with the project-specific standards such as ISO 19650 (international BIM standard) is also critical in maintaining the consistency and accuracy.

5. Monitor Performance and Quality

Regular audits and intense quality checks should be conducted to ensure that the BIM deliverables aligns well with the project’s expectations. By implementing the Key Performance Indicators (KPIs) helps to track the efficiency, accuracy and also the adherence to the timelines.

The Future of BIM Subletting

With the increasing in adoption of the digital construction methodologies, BIM for GC will continue to evolve. The emerging trends such as AI-powered BIM automation, cloud-based collaboration as well as the Digital Twin integration will further enhance the effectiveness of the outsourced BIM services. The research by MarketsandMarkets indicates that the global BIM market is projected to grow from $7.9 billion in 2023 to $15.0 billion by 2028 which is driven by the increasing adoption in the construction projects worldwide.

Conclusion

For the General Contractors, BIM subletting is not just a cost-cutting measure but a strategic approach to optimize their project execution. By selecting the right BIM Services Provider, establishing the clear communication as well as ensuring the quality control, the GCs can maximize their benefits of the BIM while focusing on delivering the successful construction projects.
