The board has placed several demands on the site owner, electricity company Fortum, before work can start again on the site, local radio station P4 Stockholm reports. They include making sure no more landslides can occur, and that no work can be carried out close to areas at risk of slippage.
Prime Minister Stefan Löfven also wants to see more rigid standards applied up and down the supply chain, telling news agency TT, "We need to have strict requirements from the contractor to the subcontractor to the sub-subcontractor. This chain has to hang together, also in terms of the workplace environment."
Two builders died and one was taken to hospital after the accident at the building site in Hjorthagen, in Stockholm. The board is refusing to comment on the cause of the accident as a police investigation is now underway.
