Members of the Scottish parliament have criticised Barcelona architect EMBT for failing to respond to its proposed cap on the fees of consultants for the building.
In his monthly report on the project presiding officer George Reid said EMBT, the practice that designed the building, had missed Monday's deadline to respond to the offer. EMBT is run by Benedetta Tagliabue, the widow of the scheme's architect, Enric Miralles.

Reid said: "We have been engaged with consultants in very constructive discussions on fees – until Benedetta Tagliabue failed to respond. I am determined to continue to apply pressure on this matter."

Consultants on the troubled scheme agreed to a cap on their fees last month after the latest £37m jump in the price of the project.

In his report, published on Wednesday, Reid said the final cost of the scheme remained at £373.9m, although it raised doubt over two glazing packages.

The report said Bovis had allocated extra staff to finish the contracts, but completion dates had not been finalised.
