The deal is Kier’s first contract awarded through the new YORbuild2 framework.
The scheme will see almost 9,000 sq m of new education space built while the existing Grade II listed Pye Bank School building will be refurbished.
Enabling works are due to start next month with the main construction phase beginning in the summer.
John O’Callaghan, Kier Construction Northern managing director, said: “We’re extremely pleased to be awarded this opportunity to provide a vital new school for Sheffield.
“We deliver on average 25,000 school places every year across the north and are confident that, by working closely with the council to understand their requirements, we can build a facility the City will be proud of.”
“This is Kier’s first contract award through the YORbuild2 framework and we’re looking forward to continue working with local authorities and public sector bodies across the North of England as we help to play our part in establishing the Northern Powerhouse.”
