The cost of repairing Hawke's Bay Regional Council's leaky new office building in Napier has doubled to $2.2 million.
The three-storey building, with a floor area of 2900 square metres, was hailed by the council when it was opened in 2006 for its eco-friendly construction with natural shade, light and ventilation.
But within two years the building smelled damp and there were water marks on walls, sources said.
HBRC group manager asset management Mike Adye says an initial rough estimate for the repair work was $1 million, but after thorough investigations the figure has increased to $2.2 million to ensure the building has an effective life of at least 50 years.
The work includes re-cladding of complete sections of the building, removal and reinstatement of sections of rubberised roof covering, perimeter guttering and some windows, sealing of gaps within the fire walls, and replacing flashings around windows and at cladding joints.
The work is expected to begin next month and is likely to take up to nine months. The building will continue to operate during that period.
Last year the council began court proceedings against Herbert Construction for the costs of fixing the building.
Herbert Construction counter-sued and the matters are still before the courts. Today the council voted to award the remedial works contract to Mackersey Construction.
The $7m council headquarters, designed by Opus International and built by Herbert Construction in 2005, was officially opened by Prime Minister Helen Clark in March 2006.
