Titanic Signature Project


We were the designers of the 7m deep basement in the state of the art Titanic Signature Project on the edge of Belfast Lough.

A focal point in Belfast’s Titanic Quarter, the building’s distinctive design draws on the city’s shipbuilding heritage and is a new Belfast landmark. The site is located in challenging terrain consisting of 1m of made ground overlying some 5m of Belfast Sleech. The works were also carried out within 50m of Belfast Lough requiring designs which were all the more onerous. 

Involved with our client from the tender stage, our design to facilitate the 7m excavation of the new 100m2 basement consisted of an embedded secant pile retaining wall, load bearing piles and temporary propping. Conscious of programme requirements, we developed a scheme which only used one row of temporary propping/anchors greatly accelerating the construction time of the substructure.

Scope of Project

  • Design of the basement for this new Belfast landmark located in challenging ground conditions in close proximity to Belfast Lough.
  • The basement was excavated to a depth of 7m to allow our client to install 1000 bearing piles.
  • The 100m2 basement was constructed by the installation of 483 linear metres of 600mm diameter hard/hard secant wall.
  • Temporary works used only one row of propping/ground anchors which geatly enhanced the excavation programme.
