A contractor has been selected to lead the work at the local station, which will take almost a year to complete.
Luddon Construction has been selected as the contractor for the project, which will cost around £5 million.
Work begins in June this year, with a completion date said to be April 2023.
Scotrail have called the appointment of Luddon Construction as "a key milestone".
Funding for the project comes from the Scottish Government, delivered through Sustrans and Stirling Council. Network Rail Scotland and Serco Group have also contributed.
David Lister, ScotRail Safety, Engineering & Sustainability Director, said:
“The appointment of Luddon Construction is a key milestone in the project to redevelop Stirling station and the area around it.
“Once completed, the work will make a hugely positive contribution to providing safe pedestrian and cycle friendly areas.
“It will also help promote train travel as we continue with our commitment to delivering better environments for sustainable transport options.”
Meanwhile, Transport Minister Jenny Gilruth MSP, said:
“I’m pleased the construction contract has now been awarded for the redevelopment of Stirling Station which will allow this remarkable project to get underway.
“We have provided substantial funding for this scheme so the people of Stirling and surrounding areas can benefit from better active travel links, a new and improved facility including additional cycle parking, pedestrianised plaza, upgraded customer waiting area and much more.
“I look forward to seeing this station project develop in the coming months.”
