Iterative design is having a positive impact on data centre projects by enabling technical engineering simulation tools such as Computational Fluid Dynamics (CFD), Energy Modelling and Thermal Comfort modelling. But maximising the project benefits of employing such methods requires a different approach to project management.
Iterative design allows us to test and refine designs in the early stages, resulting in more robust outcomes and potential cost reduction. Deerns’ MEP experts use it for energy performance modelling, thermal comfort modelling, CFD, and transient modelling of failure scenarios. With respect to design coordination, the iterative design process is harnessed in the creation of federated BIM models. Making incremental adjustments based on design scenario testing and quick feedback loops helps reduces risks and deliver a well-performing final design and building performance.
But, as it does not fit seamlessly with the traditional waterfall model of project management, iterative design can cause delays and misunderstanding. The waterfall system follows a five phase process from planning through to design, implementation, verification, and maintenance. The iterative approach requires testing and verification during the initial design phase, as opposed to waiting to test on a more established model.
During practical project experience we’ve identified five themes that lie at the intersection of iterative design and project management. Understanding of and preparation for these themes is essential for project delivery that is on time and on budget:
Uncertainty of Design Timelines
The iterative approach can have an impact on project timelines particularly during the initial design phase. Allowing for the possibility of an extended design phase is an important element in embracing the potential of the iterative approach. Our experienced design and project teams guide clients through the benefits of the iterative process at an early stage to ensure understanding and buy-in from key stakeholders and the wider project team.
Early Initiation of Iterative Processes
Used to traditional waterfall-style project progression, clients and stakeholders often expect to wait until the latter stages for adjustments to the design. Project funding schedules also tend to be linked to this approach. This compromises the positive impact that early iterative design can have. Initiating and scoping iterative processes during the project’s early stages allows for broad optioneering. Starting the testing and validation phases sooner can mitigate uncertainties and provide a clearer, confidently executable path forward. Adjusting funding schedules to facilitate an extended early design phase can pay dividends in terms of costs saved by not having to undertake significant design updates at a later stage. This is backed up by research, with the Macleamy curve showing the benefits of front-loading project design processes.
Communication and Common Understanding
Effective collaboration and open communication among key project stakeholders (including project managers, designers, suppliers, and clients) are essential. This ensures everyone comprehends the iterative elements within the project, as well as their respective roles and helps build trust. We foster a project environment of transparent communication between all parties allowing us to take a single team approach towards the collectively understood design goal. This extends to our use of a lessons learned session upon completion to support the adoption of best practice for future projects.
Information Management
While offering many benefits, iterative design is not a universal remedy. It demands careful planning, information exchange, adaptability, and flexibility to succeed. We ensure that BIM is embedded into every project from the start, establishing a common data environment and standardised approach to data recording and management. In cases of data gaps or delays in obtaining critical data, informed assumptions may be necessary. Our robust data handling practices ensure these are properly documented and acknowledged for their potential impact on project timelines and outcomes.
Connecting Technical Expertise
Successful iterative design uses appropriate software tools capable of simulating building performance under specific conditions, real or hypothetical. These tools can only work with the input data they are given. Careful integration of input from all members of the project team is the essential first step towards creating an accurate and reliable digital model. We work with clients and all stakeholders to combine real world experience with specialist expertise and cutting edge technology to first produce the digital models and then to interpret, adjust and refine then so that the final design delivers against client needs and expectations.
Iterative design is a valuable tool for ensuring the robustness of design and operational building performance. Nevertheless, introducing it to projects is not without challenges. Reaching the maximum potential of the approach requires proactive planning, effective communication, and a willingness to adapt to changing circumstances. Furthermore, all stakeholders must understand their responsibilities. As experienced project managers we embrace the principles of iterative design and foster collaboration to navigate these challenges and deliver better project outcomes.
