The author has previously introduced the concept of the BIM model and its application in the planning and design stages. Today, let’s focus on how BIM models are applied during the construction phase. Without further ado, let’s dive in!
On-site Condition Modeling
This involves establishing the current status of the construction site, existing facilities, or specific areas within those facilities to provide essential on-site information for construction planning and operations.
Cost Estimation (Including Quantity Calculation)
Material quantity estimation is performed by generating reports from the BIM model, which accurately predict material needs. This allows for rapid estimation of construction components’ quantities as needed, optimizing cost-effectiveness during construction.
Design Expression
Construction models cover various disciplines such as architecture, structure, and electromechanical systems.
Based on the finalized detailed design BIM model and the predetermined construction schedule, construction progress simulation animations can be created. These serve as valuable references for decision-making by construction managers.
Detailed construction drawings are produced for each discipline in line with the construction progress. These drawings facilitate on-site construction queries and pricing.
When requesting design changes on-site, approved site change design models, along with record models and drawings, must be provided for review.
Process Planning
4D schedule planning and control utilizes 4D models to effectively manage phased construction sequences, especially in renovation, refurbishment, or addition projects. This helps control project progress, preventing delays and minimizing rework.
3D Control and Planning
Feasibility reviews use BIM models to simulate construction site operations, such as lifting activities and potential risks, helping to prevent onsite accidents.
Construction simulations employ 4D models to assess the feasibility of the originally planned construction sequence, reducing potential delays and rework.
3D models facilitate on-site layout simulations of facilities and building components, assisting with construction hoisting and providing real-time construction status monitoring.
Safety management is enhanced by using 3D models to verify on-site construction accuracy and ensure compliance with safety configurations, improving project execution safety.
Quality control is achieved by using 3D models to monitor the accuracy of construction and equipment installation, thereby enhancing overall project quality.
Equipment confirmation and delivery processes involve reviewing 3D completion models to ensure compliance with on-site construction, verifying equipment accuracy and inventory quantities. This supports the delivery of BIM completion models for future operation and maintenance.
Acceptance procedures also rely on 3D completion model reviews and on-site compliance checks to fulfill project requirements and support ongoing operation and maintenance management.
Integrated Collaboration
3D visualization and analysis simulations use the virtual space of BIM models to visually represent spatial requirements and system analyses of facilities and buildings.
These 3D models facilitate communication, coordination, and verification among project members by enabling visualization, spatial review, and system analysis, thus enhancing collaboration and integration.
Collision detection and conflict analysis are performed within the 3D visualization environment using verification software to identify and resolve design conflicts early, reducing the need for design changes.
Record Model
A record model is created using BIM technology to document all equipment information throughout the project execution process, providing essential data for future operation and maintenance.
The completion model, or construction finalization model, includes additional information and records for all equipment. After review, this model serves as a comprehensive BIM resource for future operation and maintenance management.
Construction Site Utilization Planning
3D models simulate spatial planning of the construction site and analyze construction safety. This helps identify potential spatial conflicts in advance and develop feasible construction plans.
Construction System Design
3D system design software is used to design and analyze complex construction systems like formwork supports and curtain walls, improving the constructability of these systems.
Digital Manufacturing
Building prefabrication leverages digital information technology to directly manufacture building materials or components based on 3D models, reducing manufacturing errors and boosting productivity.
That covers The Application of BIM Models in the Construction Phase. Tomorrow, we will explore how BIM models are applied during the operation and maintenance phase. Stay tuned!
