Reconstruction of the lower part of Wenceslas Square will become more expensive by up to CZK 109 million. Most of the extra money, specifically CZK 85 million, is to go toward tram tracks, which the municipality's management wants to build for future use. Construction work began last year and originally was to cost about CZK 330 million. The construction company claims it needs an additional CZK 23 million due to extra work caused by unforeseen circumstances including the demolition of concrete structures, changes in surface finishes, and other modifications. The municipality is now negotiating with Prague 1 about trams in the lower part of the square. Reconstruction of part of the square from Můstek to the mouth of Vodičkova began last April and, according to the original schedule, is to be completed this year. It is based on a project from the architectural firm Cigler Marani Architects, which was created in 2005. ČTK
