Hey BIM aficionados! ????????
Building Information Modelling (BIM) has revolutionised the Architecture, Engineering, and Construction (AEC) industry, and ISO 19650 provides the international standards for managing information throughout the lifecycle of a built asset. This guide will take you through the BIM process in 2024, from conception to demolition, following the principles of ISO 19650. ????
Introduction
Building Information Modelling (BIM) is more than just a digital representation of physical and functional characteristics of a facility. It’s a collaborative process that involves various stakeholders throughout the lifecycle of a building, ensuring that information is consistent, reliable, and accessible. The ISO 19650 standard provides a framework for managing this information effectively. ????
Stage 1: Assessment and Need (Conception)
Overview
At this initial stage, the primary goal is to define the project’s strategic objectives and assess its feasibility. Engaging stakeholders is crucial to understanding their requirements and expectations.
BIM Activities
- Strategic Brief: Develop a strategic brief that outlines the project’s goals, scope, and objectives.
- Assessment of BIM Requirements: Determine the BIM requirements for the project, including information delivery specifications and the level of detail required.
- Pre-BIM Execution Plan (Pre-BEP): Prepare an initial BIM Execution Plan, including the project’s BIM uses, standards, and procedures.
Stage 2: Delivery Planning (Design)
Overview
This phase includes the development of the design from concept to detailed and technical stages. It focuses on ensuring that the design meets the strategic objectives and stakeholder requirements.
BIM Activities
- BIM Execution Plan (BEP): Finalise the BEP, detailing roles, responsibilities, and procedures for BIM implementation.
- Common Data Environment (CDE): Establish a CDE to manage project information and ensure all stakeholders have access to up-to-date data.
- Design Coordination: Use BIM tools for design coordination and clash detection to identify and resolve potential issues early.
Stage 3: Design and Construction
Overview
During this stage, the design is finalised, and construction planning begins. Detailed construction documents are produced, and resources are allocated.
BIM Activities
- 4D BIM (Scheduling): Integrate the construction schedule with the 3D model to visualise the construction sequence and manage time-related aspects.
- 5D BIM (Cost Estimation): Use 5D BIM to link cost data with the BIM model, providing accurate budgeting and cost management.
- Model Updates: Continuously update the BIM model with construction progress and any design changes.
Stage 4: Construction and Commissioning
Overview
The construction phase involves executing the construction activities as per the plan, ensuring quality control, and preparing the asset for handover.
BIM Activities
- Site Coordination: Utilise BIM for site coordination, logistics management, and real-time monitoring of construction activities.
- As-Built Models: Develop as-built models that accurately reflect the completed project, capturing any changes made during construction.
- Commissioning: Use BIM to assist in the commissioning process, ensuring that all building systems are tested and operational.
Stage 5: Handover and Closeout
Overview
Upon completion of construction, the project is handed over to the owner. This stage involves preparing and transferring all necessary documentation for the operation and maintenance of the asset.
BIM Activities
- Handover Model: Provide a comprehensive BIM model including as-built conditions, maintenance schedules, and operation manuals.
- Asset Information Model (AIM): Develop an AIM to manage asset information throughout its operational life.
- Training: Train facility management teams on using the BIM model and associated tools for effective asset management.
Stage 6: Operations and Maintenance
Overview
During the operational phase, the focus is on managing and maintaining the asset efficiently. Monitoring performance and ensuring optimal functionality are key activities.
BIM Activities
- 6D BIM (Facility Management): Implement 6D BIM to integrate the BIM model with facility management systems, optimising maintenance and operations.
- Performance Monitoring: Use the BIM model to monitor and analyse the building’s performance, helping to make data-driven decisions for maintenance and upgrades.
Stage 7: End-of-Life and Demolition
Overview
This final stage involves planning for the asset’s end-of-life, including decommissioning and demolition. Environmental considerations and material reuse are critical aspects.
BIM Activities
- Deconstruction Model: Develop a BIM model to plan and manage the deconstruction process, identifying materials that can be reused or recycled.
- Sustainability: Use BIM to ensure that the demolition process minimises environmental impact and maximises resource recovery.
Conclusion
The BIM process, guided by ISO 19650, ensures a comprehensive and collaborative approach to managing information throughout the lifecycle of a building. By following these stages, from conception to demolition, AEC professionals can achieve greater efficiency, accuracy, and sustainability in their projects.
