Owner Novo Construction Architect Stuart Thompson General Contractor Novo Construction Engineering Office Buxton Associates Construction Period 10/2014 - 10/2015 A six storey residential building with commercial spaces on the ground floor and a basement car-park. The building has been designed as an in-situ reinforced concrete frame comprising: basement level, five storeys above ground over a footprint of approximately 300 m2. Ground conditions at the site required the use of a continuous secant piled perimeter retaining wall. The secant piles carry permanent loads from the perimeter columns above ground, with a continuous reinforced concrete capping beam to transfer loads between the columns and piles. The set-back fourth storey and flat roof will be constructed in light-gauge steel framing, designed and installed by a specialist sub-contractor, so was modelled only as applied loads onto the fourth floor slab. These loads had to take into account a request from the client to allow for future expansion of the lightweight structure to include a fifth and a sixth level. We used SCIA Engineer to perform a comprehensive structural analysis of the building, taking into account different situations that may occur during construction and after: soil interaction, connection with the piles, hydrostatic pressure on the raft, deflection, applied force/stresses on elements, and reinforcement design for 1D and 2D elements. The user-friendly interface and flexible structure of the program allowed us to adapt and implement the changes in a very short space of time. Buxton Associates (Cons Engs) Ltd
