Graham Facilities Management has taken a five-year building repair, maintenance and minor works contract with Worcester City Council.
The contract, which starts on 1 April and includes a potential two-year extension, will see the contractor deliver reactive maintenance, planned maintenance, minor works projects and out-of-hours emergency works to municipal buildings.
The company will be responsible for more than 70 properties and sites within the council's local government boundaries, ranging from public buildings and associated structures, to depots, offices, community centres, historic parks, allotments and communal areas.
These include the grade I listed Guildhall, dating back to 1721, and the Museum and Art Gallery, which was established in 1833.
The measured term partnership with Worcester City Council will be managed from the company's new office in Wythall, bordering Solihull and Birmingham.
Gareth Smyth, operations director at Graham, said: "This latest success is another important milestone for Graham in the Midlands and reflects our quality delivery, professionalism and expertise in the area. Worcester is a beautiful cathedral and university city with a suite of historic buildings.
"We look forward to bringing our collaborative approach to facilities management to Worcester City Council in support of the local community and over 100,000 residents."
