Poole Magistrates’ Court heard how Swanage and Dorset Scaffolding and Roofing Limited (SDSRL) had been contracted to erect scaffolding at the industrial unit in Alder Hills Business Park.
The scaffolding collapsed on 14 September 2015 narrowly avoiding an office worker as they left the building but resulting in serious damage to parked cars.
An HSE investigation found, the company failed to ensure the scaffolding provided was suitably designed and installed to prevent collapse during use.
The company failed to ensure the scaffolding was suitably attached to the building to withstand foreseeable wind loads.
Swanage and Dorset Scaffolding and Roofing Limited of Romany Centre Business Park, Poole pleaded guilty to breaching CDM Regulations.
The company was fined £27,000 and ordered to pay costs of £4,051.
Speaking after the hearing HSE Principal Inspector Helena Tinton said: “The company failed to ensure the scaffolding was properly secured to the building to avoid it putting workers and members of the public at risk of it collapsing in high winds.
“It is very lucky nobody was injured as result of this incident. All duty holders have the responsibility to ensure all scaffolding work is properly designed and installed by competent workers.”
