Warehousing & Logistics
Asda Stores, Telford
Asda opened its new £4 million store in Telford in February 2014. The shop had many areas which require sprinkler protection. Other than the sales and warehouse roof areas, there were additional areas such as canopies, racks, Home Shopping, ducts and the underground car park. The programming of an installation is always an important factor in a project’s success and this was carefully coordinated by Vipond.
Vipond proposed a fixed automatic sprinkler system, designed in accordance with BS EN12845. The water supplies were provided by a 300m3 storage tank of galvanised cylindrical construction with butyl liner. Hazard classification determined water discharge densities throughout. The fire classifications varied across the premises ranging from ordinary hazard class 2 (OH2) in the car park, OH3 in the sales office and High Hazard in the warehouse areas. A total of 1,628 sprinkler heads were fitted throughout the premises with almost a half of these installed in the underground car park. All sprinklers in public areas were anti vandal. The sprinklers are fed from a network of steel pipe to BS 1387/3601. Vipond’s policy is to fabricate pipework at its LPCB certificated workshop.
Stansted Airport, Essex
During 2014/15 the airside retail complex at London’s third busiest airport, Stansted, was to be completely refurbished. This involved a comprehensive strip-out and reconfiguring of the internal building fabric including the building services. The life safety fire sprinkler system was a vital part of these services and this too had to be stripped back to the main supply pipe downstream of the control valves. From 2013 Vipond Fire Protection, working closely with Carillion, and Jacobs were tasked with carrying out all operational works whilst the airport remained open for business.
The new installation was based on a complete redesign of the system to LPC regulations Ordinary Hazard Class 3 with BS EN12845 life safety enhancements. This covered 42 new retail units, food outlets and duty-free shops. The airport required two levels of protection due to congestion of services at high level, one at the ceiling soffit and one below the other building services.
Tovi Eco Park
Tovi Eco Park is part of a 28 year contract awarded to Urbaser Balfour Beatty by both Essex County Council and Southend-on-Sea Borough Council, to manage waste from households across Essex and Southend. The mechanical biological treatment (MBT) facility will treat all residual waste as well as complementing existing recycling and composting services within the region. The client required the contracts to be compliant with industry specific guidance, including Property Damage Fire Prevention for Energy from Waste Plants.
Vipond’s systems design department closely tracked those requirements during the design process to provide the solutions demanded by the client. The scope of works extended to a wide range of fire suppression systems throughout including an automatic fire sprinkler system in accordance with BS EN12845, gaseous fire extinguishing systems to BS EN15004, water spray systems and the provision of water cannon to protect deep bunkers. Sprinklers.
The scope afforded property protection with 6 installations covering over 12 distinct areas throughout the facility. With the exception of the car park these systems were almost entirely to High Hazard category.
IG55 Gas Suppression
Automatic/manual IG55 systems were installed within the Generator room, Transformer room and Electrical Switchrooms. The 300 bar systems are designed deliver a uniform concentration of extinguishing agent throughout the protected areas within 1 minute in accordance with BS EN15004.
Water cannon and hydrant supply were facilitated by a 45m3 tank with 2 electric Fire Pumps and Jockey pump. The manually operated cannons enable an operator from the security of the control room to direct a water stream at a fire within the bunkers. All in all a comprehensive series of fire protection measures are provided for by a wide range of Vipond suppression systems at Tovi Eco Park. This allows an integrated approach to the fire safety plan and the safety of the premises.
UPM Caledonian is located in Irvine, Ayrshire, The mill has been in production since April 1989 and produces high quality light weight coated paper (LWC) for use in magazine publishing and catalogues and it is the only manufacturer of this product in the UK. The paper making process extends to approximately 1 km long. Recent developments at UPM Caledonian included a modern, fully integrated biomass CHP plant to replace the existing fossil fuel fired boiler. It was felt that an automatic active fire protection system would be advantageous in terms of speed and effectiveness of response and provide a comprehensive fire safety solution to the industrial process.
It was agreed that a comprehensive detection and suppression system would be installed appropriate to the risks. Localised detection sprinkler heads were positioned in the five areas of concern. If a fire occurs in any of these areas, the deluge valve will trip allowing water to flow into the deluge nozzles and discharge foam enhanced water onto the risk. Two Triple IR Flame Detectors were strategically placed. These sense fires very efficiently and have the highest immunity to false alarms.
