Client: Sita UK Ltd
Location: Morpeth, Northumberland
Contract Value: £1.1 million
Contract Period: January 2008 until June 2008
The extension and refurbishment of the existing household waste recycling centre at Morpeth was part of a larger £5m contract for SITA UK for their Northumberland PFI Scheme. This Design & Build contract was subject to a rigorous Client / Operational Review System to ensure all schemes were acceptable to all parties involved.
The works consisted of the full closure of the existing site but working to a tight restricting programme thereby reducing the closure period of the existing facility. The major earthworks were carried out to reduce excavate and remodel the levels to ensure minimal off-site of waste materials. The existing land was on top of a land fill and a remediation strategy was implemented including a differential settlement membrane and clean clay capping. To increase the size of the site a Textomur soil retaining wall structure was formed of 75m by 6m high. The site included insitu concrete retaining wall 65m long with access steps and access landings to the new skips both in insitu concrete. The associated drainage scheme involved a foul water treatment station and off-site connection. The surface water including separators and storage tanks was installed to the same drainage connection. The site was securely fenced including vehicle and pedestrian access gates. The concrete slabs consisted of approx 4,000m² and tarmac access roads of approx 2,000m². The prefabricated amenity building measured 25m x 10m with flat roof and contained the controlling services. The site services included new electric supply, BT/IT connection, water connection, street lighting and separator alarms. A 750m of private water main was included in the utility service provision and installed through existing highways rising up 35m in vertical level.
