The Preston-based contractor has been selected to deliver the £6m project, which includes 27,000 sq ft of teaching space.
In addition, the four-storey extension will feature a mock ward area to support Burnley College’s health and nursing course offers.
A separate two-storey block is to provide a 10,000 sq ft sports centre comprising a gym, running track, therapy suite, dance studio and three classrooms.
Last August it was reported that Kier Construction had been appointed to deliver the project having been procured through the Procure North West framework.
However, the college has since retendered the scheme, appointing John Turner Construction Group to deliver the extension.
Plans for the Princess Way facility, designed by ABW Architects, were approved in November.
