BIM (Building Information Modeling) is a perfect solution for architects, design and construction teams to address design implementation challenges. 3D BIM coordination facilitates an evolving workflow, interoperability and collaboration between different project stakeholders. This has widened the scope and application of concept design, design development, implementation and project delivery methods.
With 3D BIM coordination, you can collaborate with designers, engineers, building services contractors and general contractors to communicate design intent and ensure the project is implemented efficiently from preconstruction concept review to construction completion. When collaboration happens at this scale, you need to consider the associated technical and contractual risks before you adopt BIM tools:
1.Data control – When using 3D BIM models, you may have different users entering data at various stages of a project lifecycle. To ensure there is responsibility for inaccuracies and control of data entry, you must ensure BIM users sign applicable indemnities, disclaimers and warranties. This will help you in controlling the movement of data and assigning responsibilities.
2.Assignment of responsibilities – Typically in BIM projects, many team members collaborate and ownership of BIM data must be clearly stated. To avoid conflict and confusion, you need to create contract documents that should clearly define ownership and assign responsibilities when using BIM data.
3.Proprietary information protection – In the process of design development and project implementation, proprietary information may be used by team members. While your client may have ownership rights for the design, contract documents need to clearly state the ownership rights of proprietary information to ensure protection.
4.Design licensing – In certain projects, designers and contractors may provide vendor designs and specifications of material and equipment. In such instances, you need to create policies to ensure that only those designs with relevant licenses for the project are used. This will help you in avoiding licensing issues of vendor designs associated with their products.
5.Consistency in the use of technology – When adopting BIM modeling and coordination processes, to maintain an efficient and smooth workflow, you need to ensure that different project stakeholders, who need to work collaboratively, are using software versions that are compatible. All users must be informed about changes in versions and software updates. Based on the BIM environment you choose, whether closed BIM (the use of the same software and version) or open BIM (the use of neutral or compatible file formats), you need to make sure this selection is agreed at the outset of the project. This will help in avoiding compatibility issues that may arise in the later stages of the project lifecycle.
In any collaborative environment, clearly defining responsibilities and rules will help in improving teamwork of various project stakeholders. You may adopt an Integrated Project Delivery (IPD) strategy to build successful working relationships and facilitate efficient collaboration between your entire design, engineering and construction teams. While there is no secret formula or a common risk mitigation strategy, you can reduce conflicts and confusion by adopting best practices and creating well-defined contracts. By clearly specifying the roles, responsibilities and accountable members or groups, it will help you to create a successful collaborative environment and embrace an evolving concept such as 3D BIM coordination.
With BIM modeling you can improve the process of concept design, design development and communication of design concept to project stakeholders and clients. As new BIM technology is introduced, the next step would be to adopt a cloud-based BIM collaboration tool, such as A360 Collaboration for Revit (C4R). With cloud-based BIM tools, you can facilitate ‘borderless’ collaboration and allow project stakeholders to work on a model simultaneously from different sites, anywhere, anytime and on any device. By adopting BIM, you can improve collaboration between project teams, optimise project duration, reduce cost and strengthen client relationship.
