Carillion has marked the topping out of a new University of Birmingham library.
The £42 million building at the Edgbaston campus will include a variety of learning spaces and an audio listening room.
Four editing suite booths will be developed and study/research desks will be installed.
The building will have an 'Excellent' BREEAM rating and will provide a 50% reduction in energy usage compared to the existing library.
A plaque was unveiled by Vice-Chancellor Professor Sir David Eastwood at the ceremony to mark the occasion.
Carillion Building Director, Mark Nicholson, said: "It is very pleasing to reach this important stage of construction on programme while achieving very high standards of quality which is testament to the hard work and dedication of both the University and Carillion project teams.
"We are delighted to be working in partnership with the University of Birmingham to provide this exceptional new library which we hope will inspire students and enhance their learning experience for many years to come."
Diane Job, Director of Library Services at the University of Birmingham said: "We are delighted to reach this important milestone in the construction of what will be a truly inspirational place for people to work and study."
The development is due for completion in March 2016.
