Siren will warn of the end to Greyfriars bus station in Northampton

A loud siren will sound around Northampton shortly before 2,200 explosive charges reduce Greyfriars bus station into a mound of rubble.

Final ‘enabling’ works are currently being put in place before the former bus 
depot is demolished this Sunday.

DSM Demolition project manager, Billy Young, confirmed that a warning siren would sound five minutes before the demolition is due to take place – and another one minute before – to warn people that the building is set to be brought down.

Mr Young stressed there will be no public viewing areas during the demolition and he asked that people did not talk to stewards posted around the exclusion zone on the day.

“The exclusion zone is in place for two reasons,” he said. “Public safety and public safety. We ask that people let the stewards do their job.”

An exact time for the demolition is not known as it will depend on how quickly the surrounding area is evacuated. In the next few days, a third party engineer will be visiting Greyfriars to check the enabling works.

A specialist consultant employed by Northampton Borough Council and the Health and Safety Executive will only give the demolition the all clear after a thorough assessment of the site.

On Sunday, as soon as the building has collapsed, a team of 40 workers will move in with street sweepers and pressure washers.

Operatives will remain on site until July, clearing away the rubble, but Mr Young said any noise would be no more than its present level.

He said: “We have four to five months here, we want to remain a good neighbour.”

Mr Young said DSM had now heard back from nearly all of the 414 properties 
contacted in the exclusion zone.

But the demolition expert, who presided over the implosion of Leicester’s 1970s-built council office a fortnight ago, said he was glad to be reaching the end of a lengthy demolition project.

“Some buildings we have knocked down are architecturally beautiful,” he said. “But sometimes they are just unsafe and no longer fit for purpose.

“Greyfriars has passed its sell-by date and it’s time this building moved on.”
