Kirkcaldy Sherriff Court heard that in early January 2015 an elderly gentlemen who suffered from a number of age-related illnesses, walked onto the construction site which was closed for the holidays.
While on the site operated by Sandford Park Ltd he fell into a flooded excavation and died from drowning.
An HSE investigation found that Sandford Park failed to install the appropriate level of fencing around the site to prevent members of the public including vulnerable adults and children from accessing the construction site.
Sandford Park of Glasgow pleaded guilty to breaching CDM Regulations and was fined £110,000.
Speaking after the hearing HSE Inspector Gillian Anderson said: “This tragic incident could have been prevented, had the company installed a continuous fence around the site.”
