Jet Aire of Leeds, UK recently oversaw a technically demanding contract in support of
Manchester Airport’s largest ever programme of investment which is expanding Terminal 2 by 150% in tandem with the associated development of the airfield.
Main contractor, Galliford Try, is overseeing a £92 million upgrade of the airport’s infrastructure involving the extension of the airfield’s west apron, including construction of new taxiways and aircraft stands, along with associated stand reconfigurations, ground lighting, drainage,communication networks, security fencing and aircraft control systems. Working on behalf of Manchester Airports Group, Galliford Try has carefully planned a programme of works whichallows the airport to remain fully operational throughout.
Galliford Try required Jet Aire to carry out an extensive upgrade to the drainage network which included approximately 250 linear metres of liner installed to 450 mm and 1,050 mm diameter concrete pipework. The project involved a very high level of risk management due to the sewer system’s location directly below the runway. It required meticulous scheduling and the use of trenchless techniques which minimised disruption and time spent on site. Safety issues were further complicated by the timing of the project, which needed to be carried out during lockdown at the height of the Covid-19 pandemic.
Jet Aire used its ultraviolet lining system to install the liner, allowing the work to be completed without invasive excavation. The liner was impregnated with light sensitive resin, pulled through the pipework and inflated with air. Jet Aire then pulled a UV light train through the run, curing the resin and sewer lining in place. The crew worked in conjunction with Terra Solutions Ltd to deliver the programme safely, successfully and on budget, enabling related construction to proceed without delay.
Valued at £150,000, Jet Aire’s contract illustrated the benefits of trenchless drainage maintenance in maximising efficiency and reducing costs. In comparison, the additional resources and extended downtime involved in the excavation of the runway would have involved an estimated cost of around £2.5 million.
The total scheme at Manchester Airport represents one of the biggest construction programmes in the north of England with 1,200 people working on site. The development will deliver 148,000 sqm of new taxiway and apron, 95,000 cubic metres of concrete and 25 miles of cabling with the aim of all excavated material being diverted from landfill throughout.
