6.3. INNOVATIONS AND METHODOLOGIES FOR SUSTAINABILITY

While in the previous Units several technological and methodological innovations have been discussed, for project management a cutting-edge innovation is Virtual Design and Construction (VDC). It is a technology that aids in the coordinated management of comprehensive performance models for design-construction projects, which encompasses various aspects such as the facilities themselves, work processes, and the organization of the design-construction-operation team.

Virtual Design and Construction (VDC) is an advanced technology that enhances project management in construction. It integrates all aspects of a project including the physical building, workflows, and the teams involved, enabling more efficient management. This coordinated approach ensures that every part of the project works together seamlessly, improving overall outcomes. VDC is built around the concept of using computer software to create detailed models of the project, allowing stakeholders to visualize the project before it is built.

Imagine you are organizing a community event. Instead of planning everything at once, you create a detailed blueprint of the event, including layout, activities, and team assignments. By visualizing all parts of the event, you identify potential overlaps and conflicts early on, ensuring everything runs smoothly. This is similar to what VDC does for construction projects.

VDC involves using digital tools, such as Building Information Modeling (BIM), to visualize, simulate, and coordinate various aspects of a construction project. It enables better collaboration, clash detection, and data-driven decision-making, leading to improved project coordination, cost control, and reduced rework.

Using tools like Building Information Modeling (BIM), VDC allows project teams to create detailed digital representations of the project. This helps identify clashes or conflicts between different elements of the project before construction begins, reducing costly errors and rework. It also fosters collaboration among team members, as everyone can access the same information and work together more effectively, leading to better decision-making.

Think of VDC as a GPS for a long road trip. Just like a GPS helps you navigate and avoid traffic jams or roadblocks, VDC helps project teams foresee potential issues and adjust plans accordingly, leading to a more efficient construction process.

VDC offers several benefits, such as; Integrated Approach with a Common Data Environment (CDE) and allowing communication and collaboration with different project team members, third-party members and other stakeholders.

One of the key features of VDC is its Integrated Approach. It uses a Common Data Environment (CDE) where all information related to the project is stored and accessible to relevant parties. This means that different members of the project team, including architects, engineers, contractors, and even external stakeholders, can easily access and share data. This enhances communication, reduces misunderstandings, and ensures everyone is aligned on project goals and progress.

Imagine a team project in school. If each member has access to all the drafts and notes in a shared folder, it's easier for everyone to stay on the same page, ask questions, suggest edits, and ultimately create a successful final project together. VDC creates a similar environment for construction teams.

• Risk mitigation and Enhanced safety for workers and end-users, as the level of detail allows decision-makers to identify potential hazards and mitigate them

VDC enhances safety through its detailed modeling capabilities. By using comprehensive visualizations, project managers can identify potential hazards and risks before construction begins. This proactive approach allows them to design solutions or safety measures in advance, protecting both workers on-site and future users of the building.

Consider a movie director reviewing a detailed storyboard before filming. By identifying dangerous scenes or complex shots in advance, the director can plan for safety measures such as stunt coordinators or special effects, ensuring a safe shooting process. Similarly, VDC allows for the identification of risks in construction projects.

• Sustainability that can be conceptualised and planned for, as VDC can support assessment of energy efficiency, carbon emissions, environmental impact, embodied carbon, etc. It can not only help incorporate strategies like, adaptive reuse of materials, but also aid design of improved IEQ and plan for future use.

VDC plays a critical role in sustainability by supporting thorough assessments of various environmental factors. It can analyze energy efficiency, track carbon emissions, and evaluate the overall environmental impact of a construction project. By utilizing this data, project teams can make informed decisions that not only lessen the project's environmental footprint but also enhance its sustainability. This includes reusing materials and designing buildings for future adaptability.

Think of VDC like a fitness tracker for buildings. Just as a fitness tracker monitors your calories burned and sleep patterns, VDC monitors environmental impacts, helping teams understand how to make their projects healthier for the planet.

The VDC is a combination of several tools and can to be tailored, such seen in the Singapore VDC Framework below which boasts the slogan “Build Twice” (first Virtual, then real).

The Singapore VDC Framework illustrates a tailored approach to VDC, emphasizing the process of 'Building Twice’. This means that a project is first fully conceptualized and refined in a virtual environment using VDC tools before moving to real-world construction. This method allows for extensive planning, testing, and optimization, ensuring that by the time construction starts, the project is well-prepared for execution.

This can be compared to rehearsing a play before the actual performance. The cast practices and refines their roles in a rehearsal, addressing any issues before the audience arrives. Similarly, VDC lets construction teams rehearse their project in a virtual space to avoid problems when it’s time to build.

In essence, this technology – which is a culmination of all the understanding, knowledge, discussions, and practical applications so far explored in this book, bringing sustainability hand in hand with design and construction, is the apt point for reflecting on the global and societal impact of civil engineering and the great onus on the future civil engineer.

The advancements in VDC signify a turning point in civil engineering, illustrating how technology can integrate sustainability with design and construction practices. As future civil engineers learn to utilize these tools, they will play a pivotal role in shaping a sustainable built environment that positively impacts society globally. This reflects an emerging responsibility where engineers must not only focus on building structures but also on enhancing their sustainability and societal benefits.

Think of civil engineers as gardeners. A gardener understands that it’s not just about planting flowers but about nurturing an ecosystem that benefits everyone. In the same way, future civil engineers have the responsibility to cultivate buildings and infrastructure that contribute positively to communities and the environment.
