International lessons: Increasing BIM use in New Zealand’s Construction Industry

Building Information Modeling (BIM) has become an indispensable tool in modern construction, offering substantial benefits throughout the Project Life Cycle (PLC). This advanced technology, which simulates buildings and resolves issues before construction begins, has seen effective implementation globally. A recently published article in the Journal of Engineering established lessons from Iraq for implementing BIM modelling for the construction industry.

As New Zealand continues to advance its construction methodologies, there are valuable lessons to be learned from successful BIM implementations elsewhere. This article explores how New Zealand’s construction industry can benefit by adopting practices and strategies proven effective in Iraq.

The Relevance of BIM in Construction

BIM enhances construction projects by integrating various phases of design, planning, and execution, offering multiple advantages such as:

Early Problem Detection and Resolution: By simulating every stage of a project’s lifecycle, BIM identifies potential issues before they arise, helping to mitigate risks, reduce costs, and prevent delays.

Enhanced Visualisation: Detailed visual models help all stakeholders understand a project’s complexities, facilitating clearer communication and better decision-making.

Boosted Collaboration: BIM fosters teamwork by ensuring that all project participants can share a common platform, working synergistically towards unified goals.

Iraqi Implementation: Research Methodology

Research conducted by the Department of Civil Engineering at Baghdad University highlights several key factors contributing to BIM’s successful implementation. The study utilised:

Literature Review: Examining existing research to pinpoint crucial success factors for BIM.

Interviews: Collecting insights from the Central Bank of Iraq (CBI) building team to understand practical challenges and solutions.

BEP Enhancement: Focused on improving the BIM Execution Plan (BEP) for better outcomes.

Core Findings for New Zealand

The research undertaken by H. S., Mohammed and,M. A., Hilal underscores the importance of collaboration and communication in achieving effective BIM implementation. The adoption of the BIM Execution Planning Guide (BEP Guide) and the AEC (UK) BIM Protocol 2012 V2.0 has shown to improve project management and execution significantly.

Elements of a Robust BIM Execution Plan (BEP)

For successful BIM integration in New Zealand’s construction projects, a well-structured BEP should include:

Process Map: Detailed documentation and mapping of the collaborative process required for the BIM project.

Information Exchange Requirements: Ensuring all team members can access necessary data and updates throughout the project.

BIM Data Management: Implementing standards for efficiently managing and storing BIM data.

BIM Model Management: Establishing clear procedures for creating, handling, and updating BIM models.

Quality Control: Regular quality checks to ensure the project maintains high standards at every stage.

Addressing Implementation Challenges in New Zealand

New Zealand can benefit from strategies used successfully in Iraq to overcome BIM implementation challenges. Key steps include:

Facilitating Collaboration: Improve communication channels and ensure stakeholder collaboration.

Providing Training: Educate project teams on BIM tools and processes to optimise their use and integration.

Adopting Standard Protocols: Implement standardised protocols like the AEC (UK) BIM Protocol to achieve consistency and streamline processes.

A practical implementation of increased BIM use in New Zealand’s construction industry entails a focused effort to enhance collaboration and communication. By adopting a robust BEP and adhering to established processes and standards, New Zealand can leverage the full benefits of BIM, leading to more efficient, cost-effective, and successful construction projects.

Drawing from the experiences of Iraqi construction projects, New Zealand can overcome traditional challenges and drive future growth by fully embracing BIM. This strategic move will not only align New Zealand with global construction standards but also pave the way for a more innovative and efficient construction sector ready to tackle the demands of tomorrow.
