Hungate development is a series of five residential blocks situated within the city walls of York. Block F consists of 101 – one, two and three bedroom apartments and a community centre that adjoins a multi-storey resident car park.
The building consists of a 6 to 7storey reinforced concrete frame structure clad predominantly in brick. The adopted structural system comprises in-situ flat slabs supported on reinforced concrete columns and shear core walls that transfer loads onto pile caps, and in turn CFA piles.
The site was previously occupied by a gas works which meant that there were elevated levels of the contaminants in the soil that required remedial action and there was also a major river running within a few metres of the site.
We were appointed to produce designs for various elements of the building along with foundations for the car park which has a steel structure.
To reduce the carbon footprint of the project our high end analysis techniques and technologies meant that we made significant savings in several areas including slab depth reduction, a rationalisation of the masonry support on upper floors and a reduction in the volume of concrete required per level. Shear cores and wall thickness were also reduced.
Our designs included an innovative semi suspended ground bearing slab which required additional technical documentation to gain approval and warranty from the NHBC.
