The project being overseen by main contractor Mace, is part of a redevelopment by the Royal Borough of Kensington and Chelsea to provide a new two form entry primary school in the heart of Chelsea. It has seen the old unsuitable Victorian school building on the site demolished and the construction of a new Marlborough Primary School. The new school is larger than old one and provides 5,668 sq. m of space including new halls, studio space, classrooms and a biodiversity roof. External play spaces are also larger than the old school and include a Multi-Use Games Area (MUGA) on the top level. All electrical work on the school has been overseen by PhoenixME Limited who specified using Wieland’s Metalynx2, a prefabricated wiring system for the distribution of all lighting and power supply throughout the new build. This also includes the installation of home runs, master distribution box, extender cables, fused spur units and T connectors. Wieland’s modular wiring system has been specified for this project as it offers total flexibility and should any layout need to be changed during fit-out or at any time in the future, Metalynx2 can easily be adapted to suit any new power or lighting configuration. Darren Davies, PhoenixME project manager commented: “We are very familiar with the Wieland system having used this on many projects and are always happy with the results. .Metalynx2 is quick to install as all components arrive on site ready to connect, which is imperative when we are up against tight project deadlines. The system comes colour coded and polarised which dismisses any chance of installation error. The system is also circular which means it can be easily installed through fire barriers and stud walls”. Bringing More Structure To Wiring Wholesalers have a key role to play in educating their customers about the benefits of structured wiring systems, says Mark Redfern of Wieland Electric Electrical contractors are under constant pressure to work smarter and more productively, adding more value to their customers as a way of differentiating themselves from competitors. Electrical wholesalers, therefore, have an important role to play in helping their contractor customers 'up their game'. A good example of this is the opportunity to take advantage of structured wiring systems as an alternative to traditional cabling methods. The use of structured wiring with 'plug and play' connectivity has been shown to deliver significant savings in installation time. From the wholesaler’s point of view, these products also provide a better margin than standard cabling products. Nevertheless, some traditionally minded electricians may need reassurance that structured wiring offers real benefits. So it's worthwhile pointing out that, based on dozens of different types of project, savings in installation time of 70% are typical when structured wiring systems are used. When this data is analysed intelligently, by taking into account the slightly higher capital costs of structured wiring compared to traditional wiring, there is still typically an average 30% saving on final installed cost. Whilst this is an average saving across all project types, there are some projects where the benefits are even greater. Obvious examples include high bay lighting in 'shed' type buildings where any work on the lighting will require specialist access equipment. In such cases, as well as reducing installation time and working at height, additional savings are achieved by minimising disruption of the operations at ground level. All of which contributes to improved margins for the wholesaler, enhanced productivity for the contractor and a better solution for the end customer. And there are also other benefits. For example, structured wiring systems enable contractors to make better use of their multi-skilled operatives. The plugs on such systems are configured so they can only be plugged in one way – the correct way. This means that a qualified electrician isn't required to make these connections. An obvious example is the use of mechanical operatives working at high level on pipework to also make the lighting connections. Of course, it's essential that connections at the board are made by qualified electricians but a simple plug-in operation is well within the scope of any multi-skilled operative.
