 Along with the main work of replacing the crumbling stone and cinder terracing with concrete terracing and installing a roof over the previously open terraces, many other minor improvements were completed, such as the installation of new perimeter fencing, new seats in the main stand and undersoil heating and a digital scoreboard (although the famous old manual scoreboard in the corner between the Gegengerade terrace and the Zuckertor(waldseite) end of the ground has been retained).Most of the work during the redevelopment was carried out by over 2,300 supporters volunteering their services.Specialist firms were only called in for more complex tasks such as installing the cantilever roof.
