Plans to demolish Gasklockan were formalized in 1999 when Göteborg Energi applied for demolition permission with the
county administrative board. The process continued for 14 more years before getting the green light in April 2013. By this time two endangered
peregrine falcons had built a nest in the abandoned building requiring an exemption to the endangered species protection regulations. The application process was started immediately after getting approval and came to an end in December 2014 when the county granted the exemption conditioned on the falcons finding a new nest. A demolition company was contracted to perform the demolition, but the process was appealed by another demolition company taking part in the negotiations. The appeal was rejected by the
administrative court in October 2015, but the decision was once again appealed to the
administrative court of appeal in November 2015. Göteborg Energi decided to redo the entire bidding process for the contract in March 2016. Demolition was scheduled to begin early September 2016, but was delayed just days away. The demolition was rescheduled to start in February 2017, but if any further delays occurred the demolition would not be finished before the nesting season for the birds requiring it to be delayed until September. The demolition began in early 2017 and was performed by lifting the building using 20
jackscrews and removing the bottom most section. Using this process the building lost 2m height a day. It was finished before the March 15 deadline, but the falcons were present on the building while demolition was underway. The birds had been provided nesting boxes placed on alternative nesting sites. ==References==
