Constructed by main contractor, McAleer & Rushe, the Stansted hotel is part of a drive by Premier Inn to become the UK’s largest airport hotel provider. The hotel is close to existing water and gas mains, but there was no existing pipe work connecting the site to the utilities, so subcontractor, H J Services & Sons has laid a total of 192 metres of GPS Excel (PE100) water pipe and 312 metres of GPS PE80 gas pipe.
McAleer & Rushe specified PE pipe for the installation due to its proven performance, competitive cost and durability. Both gas and water pipes were laid in an open cut installation with lengths of pipe welded together to form strings before being lowered into the trench.
For the water pipe installation, H J Services & Sons has used a combination of 125mm and 90mm blue Excel piping in SDR17 to manage varying levels of water pressure, which reaches six bar in some areas of the site. As gas pressure to the site is low, the contractor has used a larger 180mm diameter size of yellow PE80 pipe in SDR17.6 to ensure that there is sufficient flow of gas to serve the new hotel’s ongoing requirements.
Comments Dan Morgan from H J Services & Sons: “One of the many advantages of using PE pipe is that we can adjust the diameter and SDR of the pipe for different parts of the site to adapt to the available water or gas pressure. The pipe networks have been fast and trouble-free to install and connect up to the mains and will provide a safe and reliable gas and water supply to the hotel for a service life of at least 100 years.”
