Virtual Prototyping
We utilise virtual prototyping right from tender stage designs, using multiple methods of assembly. This approach serves as an effective tool for selecting the most suitable contractor and system, and enables clients to progress smoothly to the procurement stage. We have a deep understanding of the capacity and capabilities of leading façade fabricators and system manufacturers. This expertise allows us to create tender design packages that are open to a broader selection of contractors. This approach promotes competition and helps to ensure that our clients receive the best possible solutions at a competitive price. This approach not only helps to ensure the success of the project, but it also promotes efficiency and transparency throughout the procurement process.
Our engineering approach involves the creation of virtual prototypes of selected building envelope bays, which serve as representative samples of the building's façade. We carefully select areas of the building that contain all of the critical interfaces of the concept design, allowing us to resolve all essential details and select the most appropriate system, fabrication method, and construction methodology. This approach ensures that we consider all key factors, such as budget constraints, logistics, and desired performance parameters, in our decision-making process. By developing virtual prototypes and analysing the selected bay, we can identify and resolve any potential challenges and ensure that the final design is both constructible and cost-effective. Here is an example of typical façade bay we have delivered at preconstruction service stage:
The selection of the right façade system is a critical aspect of building design, as it can have a significant impact on the overall performance, durability, and aesthetics of the building. In order to make an informed decision, it is important to consider the specific requirements and constraints of each project. To facilitate this process, we approach the selection of the right system by developing virtual prototypes of a selected façade bay using several different systems. This allows us to compare and evaluate the performance, cost, and feasibility of each system and make an informed decision. While masonry assembly may not be the best option for all building types, it can be a good choice for low- to medium-rise buildings where scaffold access is readily available. This is because masonry assembly requires significant manual labour on site, which can be challenging in high-rise buildings where scaffold access could have adverse impact on the projects programme.
For medium to high-rise building facades, brick-slip rainscreen systems can be a viable option if the project timeline and build-up thickness are the primary considerations. This approach provides the appearance of a traditional masonry wall while offering the benefits of a modern rainscreen cladding system. When considering this type of cladding, the program timeline and build-up thickness are critical factors. If these elements align with the requirements of the project, a brick-slip rainscreen system can be a cost-effective and visually appealing option.
For high-rise buildings with repetitive window designs, the use of precast concrete or unitized façade assemblies should be considered. Precast concrete is a type of concrete that is cast and cured in a controlled environment and then transported to the building site for installation. This method of construction provides a number of benefits, including improved quality control, increased speed of construction, and reduced on-site labour requirements. Unitized façade assemblies, on the other hand, are pre-manufactured, complete façade panels that are assembled in a factory and then transported to the building site for installation. This method provides many of the same benefits as precast concrete, including improved quality control and reduced on-site labour requirements. When designing a high-rise building with repetitive window designs, these types of façade systems can offer significant advantages. The repetitive nature of the window designs makes them well-suited for precast concrete or unitized façade assemblies, as these systems are optimized for mass production.
To select the right system, we develop selected façade bay in several different systems. For example, traditional masonry assembly could be selected for low- to medium-rise buildings with scaffold access.
Our team adopts a comprehensive approach to façade design by developing virtual prototypes of a selected bay in multiple systems. This allows us to address various challenges and mitigate risks prior to contractors' appointment. We consider key factors such as structural design, logistics, accessibility for construction and maintenance, thermal performance, acoustic performance, condensation risk, and risk of molding in our analysis. Our close relationship with suppliers and manufacturers enables us to make informed decisions about procurement routes and costs. With a fully developed façade bay, we are able to prepare preliminary cost estimates that support the selection of the most appropriate system for the project.
Our virtual prototypes are perfect tool for architects to communicate external envelope design to their clients and wider design team. Facades bays and details can be experienced in augmented reality even before the visual mock-ups are produced at later design development stages.
