![]() The Enabling Works Contract (EWC) on the southern section (Area South) is part of High Speed Two (HS2) phase one which includes demolition of buildings within the wider Euston area, utility diversions, environmental and ecological monitoring and a programme of historic environment and archaeological activities, delivered by the Costain Skansja joint venture (CSjv). 47% of deaths over the same five-year period were due to falls from height.An average of 37 fatalities to workers and five to members of the public each year over the last five years.40 fatal injuries to workers and four to members of the public in 2019/20.According to the HSE, in Construction there were These activities involve working on leading edges, where there is a risk of falls from height and significantly contribute to high risk profile associated with the work. ![]() This paper will be of interest to other projects implementing top-down demolition activities.Īcross the demolition industry, the adoption of traditional top-down demolition methodologies require activities such as the use of access platforms, scaffold erection, scaffold encapsulation and scaffold striking techniques to enable the progression of the demolition works. The paper compares the benefits of traditional versus a less traditional approach. This paper provides an overview of the two of the non-traditional solutions implemented – a demolition curtain in conjunction with a long-reach excavator, and stacked shipping containers to provide encapsulation, in conjunction with the use of a long reach excavator. Hence the Enabling Works Contractor explored alternative methods of demolition that could reduce fall from height risk by designing out where possible the installation and periodic removal of scaffolding, the existence of leading edges to lift plant down to the next floor and the use of PASMA towers to sling and support structural elements during demolition. The Enabling Works Contract on the southern section of High Speed Two (HS2) includes the demolition of 82 varying types of buildings and 2 gantry cranes. ![]() Falls from height are a key risk for traditional top-down demolition activities.
