A Review of Information Requirements in Building Information Modeling (BIM)

Abstract

This article explores the crucial aspects of building information modeling (BIM) projects, focusing on the contractual agreements and responsibilities of key stakeholders such as BIM specialists, BIM coordinators, and BIM managers. The Employer's Information Requirements (EIRs) and the BIM Execution Plan (BEP) play a significant role in defining project objectives, model specifications, and workflows. The EIR outlines the client's BIM implementation objectives, including responsibilities, handover dates, procedures, and data exchange formats. Bidders respond to the EIR with a pre-award BEP, which is further refined after contract award. Data drops or information exchanges are essential milestones in BIM projects, aligning with stages of the design process. These exchanges include models, data structures, and reports. The ISO standards of the series 19650 provide general specifications for executing BIM projects, ensuring the creation and delivery of appropriate information throughout the project lifecycle. The article emphasizes the importance of establishing clear requirements for information exchange through the EIR. It explains that the EIR evolves from a simplified information requirements process map to a detailed document that outlines the necessary information for decision-making, procurement, and asset maintenance. The EIR includes standard methods, role definitions, an information delivery plan, and a COBie demand matrix. The BIM Execution Plan (BEP) serves to showcase the capabilities of the design team and outlines the information management implementation throughout the project. It includes a project implementation plan, collaboration goals, proposed milestones, and a deliverable strategy. The post-contract BEP further details how the EIR requirements will be met and covers management, planning, documentation, and IT solutions. The article also defines the roles and responsibilities of BIM specialists, BIM coordinators, and BIM managers. BIM specialists possess domain-specific expertise and manipulate models and data. BIM coordinators manage and coordinate multidisciplinary projects, ensuring adherence to standards and procedures. BIM managers oversee information management, coordinate teams, and make strategic decisions. Overall, understanding the contractual agreements, information exchange requirements, and roles within BIM projects is crucial for successful implementation and collaboration among stakeholders.
