DBFL were engaged to provide civil, structural and transportation engineering services on this prestigious project. DBFL provided full structural design of the RC frame and double basement structures including waterproofing performace specification, civil drainage, and transport statements.
The Frame is a high-end flexible office development in a prominent corner site location on Baggot Street next to the Grand Canal at the Baggot Street bridge crossing. It’s a five-storey building over two storeys of basement with car parking in the lowest level and naturally-lit office spaces at the lower ground level. The main entrance on the corner of Baggot Street and Wilton Terrace leads to a 2two-storey atrium. The development contains approximately 6,800 sqm gross floor area.
Two-storey basement construction was achieved using a propped secant pile embedment retaining wall. The capping beam is designed to support both temporary propping loads and permanent column foundation loads.
An ESB sub-station and switch room provided at suspended lower ground level within the footprint of the building presented particular challenges to satisfy strict ESB requirements in an atypical scenario.
Long open spans with limited structural depths and tight deflection tolerances to support high performance stone and glazing were achieved by taking advantage of post-tensioning of the suspended concrete slabs.
Attaining LEED 4 Gold was assisted through specifying lower carbon content concrete and using post-tensioning of the long open span suspended slabs for greater material efficiencies in both concrete and steel.
