Twenty six year-old father-of-one Craig Page was working on the Hamsptead building site when a mini-crawler crane was in the process of lifting a skip onto the site.
The skip of ready mixed concrete overturned and the boom of the crane struck Page, crushing his upper body and killing him at the scene.
Harris Calnan Construction Co and its director Neil Harris were prosecuted by the Health and Safety Executive for failing to properly plan or supervise lifting operations on the site.
Both pleaded guilty and the firm was fined £80,000 with £66,244 in costs, while Harris was fined £7,500 and ordered to pay costs of £25,000.
The Central Criminal Court heard the construction site was poorly managed by the company who failed to ensure the lifting operation was carried out safely.
HSE Inspector, Dominic Ellis, said: “From the start of this project the defendants failed to control even the most basic of risks on the construction site. These failings ultimately resulted in the tragic and entirely avoidable death.
“The defendant’s failure to appropriately plan, manage and supervise lifting operations on site led to this incident. ”The attempted lift of a liquid concrete load at a distance far in excess of the crane’s safe working parameters was wholly inappropriate. The potential for overturn in these circumstances is well known, entirely foreseeable and could have been simply prevented.”
