This major and highly complex project comprised asbestos removal and then demolition of the multi storey office blocks known as Esso House and Glen House. The buildings rose eight, ten and sixteen storeys above ground level and incorporated several commercial, retail and restaurant units along, and adjacent to Victoria Street between Bressenden Place and Palace Street. The contract also incorporated the demolition of a large piazza and the remaining suspended ground floor of the adjacent Watney House, plus interlinking basement structures.
Notably, the scope of works included the careful removal of overburden and the demolition / dismantling of massive steel and reinforced concrete transfer structures spanning the live London Underground District and Circle Line Tunnel located immediately under Esso House running through the basement.
As a consequence the specification called for extensive safety and engineering input in the form of :
- Temporary works
- Tunnel protection measures
- Vibration predictions and monitoring
- Hydro demolition
- Specialist saw cutting.
The works were overseen by full time LUL liaison engineers who worked in partnership with our project team to ensure that the underground remained unaffected by our works.
Throughout the project extensive environmental monitoring was undertaken to provide reassurance that best practice was observed in terms of control over air quality, vibration and noise. Liaison with the local authorities, enforcing authorities, local stakeholders and the general public was dealt with through our highly skilled and experienced management team; a team which included Project Managers, Safety Professionals, Demolition Engineers, Structural Engineers, Environmental Specialists and Liaison Officers.
