BIM Implementation Workflow

BIM Implementation workflow starts by understanding the requirements and scope of work where in predesign and planning phase we are defining the need and road map of implementation.

Common data environment acts as a single source of truth. This platform mainly utilized for BIM data management with restricted access as per roles and responsibilities.

Strategy to implement BIM is recorded in documentation format at every stage of project.

Organization Information Requirement (OIR) : The OIR is a high-level, strategic document and is particularly important for establishing the foundation of information management in a BIM-enabled project.

Project Information Requirement (PIR): The PIR is derived from the Organization Information Requirements (OIR) and ensures that the project delivers the required data to meet the organization's goals.

Asset Information Requirement (AIR): The AIR is closely tied to the Organization Information Requirements (OIR) but focuses specifically on asset-related information.

Exchange Information Requirement (EIR): The EIR is a project-specific document that outlines the information the employer requires from the supply chain at key project stages. It ensures that the information delivered aligns with the employer's strategic and operational objectives.

EIR is the document which is getting share with the Invitation or Tender as client requirement. Based on the EIR BIM Consultant submits BIM Execution plan (BEP).

Project Information Model (PIM): The PIM is a digital model developed during the design and construction phases of a project. It contains all the graphical and non-graphical information necessary to describe the design, construction, and commissioning of the project.

Asset Information Model (AIM): The AIM contains all the data and documentation necessary to support the operation, maintenance, and management of an asset throughout its lifecycle. It is typically created by transitioning the Project Information Model (PIM) to operational use after construction and handover.

LOD (Level of Development) refers to the degree of detail and reliability of information in a Building Information Model (BIM) at different project stages.

4D BIM: 4D integrates time-related information with the 3D Building Information Model (BIM) to enable project teams to visualize the construction process over time.

• Most Important aspect for schedule linkage with 3D model is * Logically linked WBS wise schedule, Federated Information model.
• Model and schedule should have Unique activity Id which will help in auto mapping (Auto linkage) of activities in schedule with 3D model.

5D BIM: 5D BIM involves associating cost data with specific elements in the 3D model, enabling dynamic cost estimation.

• Two ways for 5D Implementation

1. Cost loading in schedule and linking to the model for cash flow analysis (5D)
2. Preparation of cost estimate (BOQ) with quantity takeoff in BIM Platform itself.

QTO --> Unit rate incorporate --> Cost of Non BIM activities & Expenses --> Linking to schedule/model --> Simulation and Power BI reporting

Reality Capture: refers to the process of using advanced technologies to capture the physical characteristics of a site or asset and integrating this data into a BIM environment. It provides accurate, real-world conditions as a foundation for modeling, analysis, and decision-making.

• Laser Scanning, Photogrammetry, 360 Camera, Drones
• Integrating data with BIM model

1. Point Cloud to BIM (Scan to BIM)
2. Reality Mesh Model
3. Digital Twin

IOT Integration: Integrating Internet of Things (IoT) technology with Building Information Modeling (BIM) during the Operation and Maintenance (O&M) phase transforms facilities management by enabling real-time monitoring, automation, and data-driven decision-making.

IOT Device & Sensors --> Connectivity --> Data analytics platform --> Integration with BIM model

Sustainability in BIM: Driving Green Building Practices

Sustainability in the context of Building Information Modeling (BIM) refers to integrating environmentally friendly practices, efficient resource use, and sustainable design principles throughout the lifecycle of a building or infrastructure.

We can follow the different standards (Guidelines) available for BIM implementation which will help to streamline the process.
