FiftySevenEast was a £32m residential project in Kingsland High Street in Dalston. The scheme comprised of 98 residential units above a retail unit at ground floor and basement.
The construction consisted of two towers; a 4-storey tower and a 14-storey tower with a single storey basement. A ground floor and first floor level podium structure covering the extent of the site and connect the two towers.
The structure was of in situ concrete flat slab construction throughout supported by a bored piled raft foundation. Complex transfer slabs were required 1st, 5th and 13th floors due to change in column layouts and plan profiles at these levels.
The North London Line Railway and Dalston Kingsland railway station border the site to the north and the east London Line railway borders the site to the south west. Directly beneath the site, at a depth of 34m below ground level, lie the High Speed 1 running tunnels.
CNM provided full design services for the civil structural and below ground drainage works and were also given the responsibility to directly manage the liaison with the three separate railway stakeholders as the development was immediately adjacent and above the railways.
This involved meetings with the railway’s Asset Managers to determine their approval requirements and then produce and submit the relevant design and drawing approval documents. A number of surveys and track monitoring regimes were required and CNM organised tenders for these services by specialist contractors, and then monitored the contractor’s work throughout the construction programme.
