BIM Q&A: Key Stakeholders and Their Responsibilities in BIM Implementation

Participants involved in BIM implementation span multiple sectors, including construction, BIM coordination, surveying, design, general contracting, specialized subcontracting, supervision, cost consulting, and operation & maintenance units. Their basic competency requirements include:

1. Having a professional and well-structured BIM technology team and an appropriate organizational setup;

2. Developing a project-specific BIM application implementation plan tailored to the project’s characteristics and requirements;

3. Possessing the capability to evaluate, refine, update, and maintain BIM models and related information;

4. Demonstrating proficiency in communication and collaboration through BIM technology, facilitating project management, and guiding on-site construction activities.

Responsibilities of the Construction Unit:

1. Define the BIM application mode, objectives, requirements, and identify all participating parties, including the allocation of related expenses;

2. Appoint and commission the overall BIM coordinator for the project;

3. Receive reviewed BIM delivery models and associated deliverable files.

Responsibilities of the BIM Coordinator:

1. Develop a BIM implementation plan based on project needs and oversee its execution;

2. Review and approve BIM deliverables submitted by project participants at each stage, providing feedback and assisting the construction unit in archiving BIM results;

3. Assist the construction unit in managing and maintaining the BIM collaborative management platform, including permission allocation and establishing usage protocols;

4. Provide BIM technical support to all involved parties;

Additionally, the BIM coordinator supports the construction unit in selecting qualified BIM-capable participants.

Responsibilities of the Survey Unit:

Implement a BIM-based engineering survey process aligned with the project’s BIM plan, defining tasks for different stages based on project needs;

Create visual engineering survey models to achieve 3D integration of geological data between buildings and underground structures;

Utilize BIM for numerical simulation and spatial analysis to support informed decision-making and risk mitigation;

Establish unified data format and exchange standards to ensure effective information transfer.

Responsibilities of the Design Unit:

Organize BIM implementation during the design phase in accordance with the project’s BIM plan;

Complete BIM modeling and applications for the project, including simulation, optimization, and design review, ensuring models meet depth and standard requirements;

Use BIM technology to conduct design briefings with all project stakeholders and guide construction implementation.

Responsibilities of the General Contractor:

1. Establish a BIM team to deliver BIM results in line with the project’s BIM plan, updating these models timely throughout construction to maintain relevance;

2. Based on the building information model design, enhance and optimize the construction BIM model to support detailed design, coordination, cost management, construction process control, quality and safety monitoring, underground risk control, and delivery completion;

3. Coordinate and verify subcontractors’ construction BIM models per contract requirements and integrate their deliverables into the general contractor’s BIM delivery model;

4. Ensure that all three models comply with the implementation plan’s depth and modeling standards after review.

Specialized subcontractors are responsible for refining, updating, and maintaining their scoped BIM models, guiding construction, cooperating with the general contractor’s BIM workflow, and providing BIM deliverables that meet contract terms.

Responsibilities of the Supervisory Unit:

1. Review the construction unit’s BIM models and provide feedback;

2. Collaborate with the BIM coordinator to assess the accuracy and feasibility of BIM deliverables.

Responsibilities of Cost Consulting Firms:

1. Develop BIM modeling standards suitable for cost estimation and pricing, perform quantity take-offs, and assist in project budgeting and settlement;

2. Submit BIM work results per contract requirements, ensuring their accuracy and completeness.

Responsibilities of the Operation and Maintenance Unit:

1. Collaborate early with the BIM coordinator during design and construction to define BIM data delivery requirements and formats, and assist in reviewing BIM delivery models;

2. Receive the completed BIM delivery model, establish a BIM-based project operation and maintenance platform for daily management, and continuously refine, update, and maintain the building information model to ensure ongoing applicability.
