Prefab and plug-in installation: the next step towards efficient, safe and sustainable construction
The construction sector is changing rapidly. Prefabricated construction offers an answer to current challenges such as staff shortages, high failure costs and the strong demand for housing. In combination with pluggable installation, this creates an industrial construction method that optimally combines speed, predictability and quality.
Prefab and pluggable: two worlds that reinforce each other
Prefab is based on industrial production processes in which building elements are manufactured under controlled conditions. This requires standardised, error-free and repeatable working methods. Traditional installation methods do not always fit well with this approach.
Pluggable installations bring exactly the same predictability and repeatability to installation technology. Because the components are fully tested and assembled in the factory, installation on site becomes a plug-and-play process. This saves time, minimises failure costs and ensures a consistent level of quality.
Early collaboration as a success factor
A successful prefab installation starts with coordination between all parties involved. By collaborating in the design phase with the supplier, prefab manufacturer and installer, cable routes, openings and connection points can be optimally aligned.
This integrated approach ensures that the pluggable system is perfectly matched to the production process in the factory and to the installation rhythm on the construction site. Isolectra supports this collaboration with technical guidance, design reviews and training via the Isolectra Academy.
Wieland GST and RST: technology that reinforces prefab
The Wieland GST18® and RST20® systems form the technical foundation for many prefab projects. GST18® is designed for indoor installations and meets the requirements of modular housing and utility development. RST20® is a waterproof system suitable for applications in concrete or humid production environments.
In addition, Isolectra offers its own Streda system, in which both power and data are combined within one pluggable infrastructure. This enables the entire residential or modular installation, including sockets, data points, switches and detectors, to be executed as a pluggable system.
All connections are certified, tested and coded, making incorrect connection impossible. The systems comply with applicable quality assurance requirements and make it possible to fully substantiate project handover files with demonstrable quality data.
Time savings and error reduction
Using pluggable installations results in considerable time savings. Connections can be made up to 90 percent faster, which in the overall installation process often leads to a reduction of 60 to 70 percent in installation time.
Because the components are tested in advance, the risk of installation errors is greatly reduced. Pluggable systems replace manual actions such as soldering, stripping and wiring. As a result, most of the installation work is moved from the construction site to the prefab factory, where work is carried out under controlled conditions. The result is a cleaner, faster and more reliable process.
Quality and expertise as a foundation
Speed and efficiency go hand in hand with quality and safety. Isolectra works exclusively with materials tested according to strict quality assurance systems. This takes into account the correct fire classifications, voltage levels and environmental conditions of each project.
A care home or childcare facility, for example, imposes different requirements on fire resistance than an office building. By providing advice in the design phase on the right components, Isolectra ensures that each project complies with the relevant standards.
In addition to the choice of materials, knowledge sharing is essential. Through the Isolectra Academy and extensive documentation, installers and prefab factories are trained in the correct use and locking of connectors and in the right combination of GST® and RST®. This keeps knowledge secured within the entire chain.
Sustainable and circular installation
Prefab and pluggable installation contribute directly to a more sustainable construction chain. Because all products are supplied to size, hardly any cutting waste is produced. Any residual material that does arise can be reused.
Isolectra’s pluggable systems are included in the Dutch Environmental Database and have an Environmental Product Declaration (EPD). Used components can also be taken back, tested, certified and reused in new projects.
This approach fits seamlessly within the principles of circular construction, in which materials last longer and waste streams are minimised. Various projects have already implemented successful reuse programmes, and this is expected to increase significantly in the coming years.
Prefab in practice
Pluggable installation is now widely used within the prefab sector. Isolectra supplies systems for a wide range of applications, from prefab bathroom modules and modular office units to complete residential or utility buildings in concrete or timber.
The waterproof RST® system is used extensively in prefabricated concrete and timber frame construction, while Streda is also chosen in serial prefab housing. Thanks to this flexibility, the pluggable concept can be applied in virtually any construction system.
Growing demand from the market shows that prefab and pluggable installation reinforce each other. Both stand for speed, precision and controlled quality.
The future of prefab: digitalisation and integration
The next step in the development of prefab lies in the digitalisation of the design process. Isolectra is working with manufacturer Wieland on a new design tool that will allow pluggable installations to be integrated directly into BIM models.
With this tool, installers and construction partners will be able to design pluggable installations in 3D within Revit or AutoCAD and export the data using IFC files. This brings together design, product information and execution in a single process. The package will be made available free of charge to partners and installers to further strengthen collaboration in prefab projects.
Looking ahead: prefab as the new standard
Prefab construction is expected to play an even more important role in the coming years within the construction sector. New factories and production lines are increasingly focusing on standardised production processes in which installation technology is also included in the industrialisation.
As prefab continues to grow, pluggable installation will become the standard within this way of building. The combination of speed, safety and sustainability makes it a logical step towards the future of efficient and circular construction.
Prefab and pluggable installation share a common objective: a predictable, reliable and sustainable construction process in which quality is demonstrable and efficiency becomes the norm.
