Viega’s Megapress press connection technology has been installed across 11 floors of a new £85 million development, 125 Deansgate in Manchester. Selected for its speed of installation and its reputation as a trusted method for connecting thick walled steel tube without hot works, the Megapress connections have been used throughout the heating system.
With 12 floors in total, 125 Deansgate echoes the industrial Victorian architecture of the Deansgate area and comprises 117,000 square foot of offices above 12,000 square foot of retail space at ground floor level. The development is expected to achieve a BREEAM Excellence rating on completion.
Briggs & Forrester Engineering Services Ltd. were awarded the M&E contract by main contactor Marcus Worthington & Co. Ltd. and began on site in May last year. Briggs & Forrester had not previously worked with Viega’s Megapress system in its northern region so this was the team’s first experience of the product.
On the decision to use it in this development, Richie Jones, Site Manager for the company commented: “The project specification suggested using a crimp system for the pipe connections, but Briggs & Forrester Engineering Services do not use lightweight carbon steel crimp systems, so we were looking for an alternative.”
“Our sister company, Briggs & Forrester Living highlighted that they had used a Viega press connection system on one of their projects and had also been on a Viega factory tour where they had been impressed with the Megapress system. After researching Megapress and the installation process ourselves, we decided to use the product for 125 Deansgate.”
In total, approximately 7,000 Megapress connection joints were installed, with somewhere between 500 and 650 joints being used per floor across the 11 floors of office space.
Richie highlighted that while Briggs & Forrester were working to a tight programme, Viega’s Megapress helped the company to meet its installation targets though its simple installation process.
Using Megapress press connections can provide a 60% to 80% time saving compared with alternatives such as welding, grooving or threading tube.
Viega’s proven SC-Contur technology is also designed to deliver a 100% positive leak if a fitting is left unpressed which is clearly discernible during leakage testing or when the system is filled for the first time.
This prevents costly remedial work that might be required later on and can again save contractors a significant amount of time on site.
Richie continued: “The installation of the Megapress connections was simple and we did not have any issues with the products. There is a good selection of connections to choose from to suit any installation requirement and the system is also simple to clean which reduces the flushing time and overall cost.”
“We will definitely use Megapress again - using Viega is like going back to using traditional heavy grade steel pipe systems but with a modern twist.”
Paul McCormick, Senior Project Manager at Marcus Worthington & Co. Ltd commented, “As yet, Briggs and Forrester have not started to test the system; however, from a safety stand point the Megapress system is much better than traditional brazed pipework as it cuts down on the number of live hot works permits required at any one time and is also less prone to workmanship errors. I look forward to seeing the system prove its reliability during testing.”
