The RAF Benevolent Fund commissioned the team to look after the £6m stone memorial and surrounding grounds including tree care and electrical upkeep.
Landscape and design consultant Greenmantle incorporated 25 mature specimen trees including Cratageus Monogyna, Quercus Robur, Tillia Europea pallida and Aesculus indica into the design, remodelled 2,000sq m of Green Park and turfed 3,800m of land. Contractor Gilbert-Ash NI installed CellWeb tree ventilation as well as irrigation.
Fund chief of staff Mike Neville said: "Serco has a track record of providing top-class support services and will keep the memorial in peak condition providing a place of solace for relatives."
The Bomber Command Memorial commemorates the loss of 55,573 airmen who died in World War Two and pays tribute to air force staff who survived the campaign. It was designed by sculptor Philip Jackson and architect Liam O'Connor.
Turf, resin-bonded surfacing and both mature and semi-mature trees surround a bronze sculpture in the white masonry memorial with columns, all of which need careful attention, said Serco.
"This memorial will be a lasting tribute for veterans and their families. We have wide experience of offering operational, management and consulting expertise in the aviation and defence sectors for governments, agencies and companies."
