The modular manufacturer sent its design proposal to Uponor for review as it required a leak-free plumbing solution for its off-site construction projects. Working with their design engineers, Uponor advised on what products were available, which ones would suit the project, where cost savings could be made and then re-worked the design to offer a higher standard product solution.
As a result, a total of 120,000m of MLC pipes were supplied for the project. The MLC pipes consist of an aluminium core, which is layered inside and out with high temperature resistant polyethylene to provide a smooth internal surface which reduces friction losses and helps to maintain pressure guaranteeing a good flow of water to each outlet. The pipe also provides excellent flexibility for a faster install time, while the press fit system cleanly forms a robust connection with no need for hot works whilst also providing a feature to allow a review of the connection following the installation.
Completed in just 24 weeks at a factory in Bedford, George Street is testament to the benefits of off-site construction such as increased quality, reduced project delivery times, reduced waste, fewer on-site trades, greater control over costs and also demonstrates that MMC (Modern Methods of Construction) can deliver more sustainable buildings, whilst perfectly meeting the design and with assured quality for the project.
A total of 1,500 modules were constructed off-site at the Bedford facility where kitchens, bedrooms, living rooms and bathrooms were completely assembled and finished including wiring and plumbing before being transported to site and craned into position where each module has the final service connections made to join the assembly on to the building’s central services network.
Uponor worked closely with the modular manufacturer and its employees to ensure the pipework and manifolds were installed to a high quality. Uponor’s team were on hand throughout the project to offer advice and assist with regular reviews of installed products and the calibrated press tooling being used.
As the contractor’s employees were unfamiliar with the installation of the Uponor MLC pipe system, Uponor provided on-site installation and safety training which was translated by the contractor’s team in to several languages so that every engineer was trained to the same standard all on the same day. Once completed, to ensure that each installation was assembled correctly and up to the expected high standard, each module was pressure tested using air.
- Uponor supplied over 120,000m of MLC pipework and 2,250 manifolds, used to supply the hot and cold water to each apartment.
- Uponor helped to ensure that each of the 546 apartments was of the highest quality by providing bespoke on-site installation training to each of the engineers.
- Being involved early in the design stage, Uponor was able to advise on the most suitable products, and where savings could be made on previous designs without compromising quality or performance.
- The success of Uponor’s products within the design specification means that it can now be replicated across all of the contractor’s similar projects.
