The project involved the design and construction of two multi storey residential apartment buildings to form phases 4A and 4B of the award winning Ingress Park development in North Kent. The apartment blocks were 6 and 8 storeys respectively and were to provide 118 high end luxury apartments including duplex penthouses on the upper storeys. Both buildings incorporated provision of a single level of basement car-parking under the entire footprint of the blocks. The development also included provision of external at grade landscaped areas.
Fairhurst were appointed to provide all Civil and Structural Engineering design services including the design of the building superstructures, foundations and sub-structures including design of the basement structures. As part of our commission we carried out a Geo-Environmental evaluation of the site to establish the ground conditions and also designed all below ground foul and surface water drainage and external works.
The foundations and basement walls were formed using CFA piles with RC pile caps. The building structures were both RC frames with flat slabs at each floor level and to accommodate the basement car-park grid a transfer structure was required at ground floor level.
Due to the close proximity of the new buildings to existing roads, the basement retaining structures were Highway retaining therefore required AIP approval from the local authority Highway’s team.
Our permanent site attendance during basement and transfer slab construction to inspect for quality and carry out record keeping of retaining walls for Kent County Council Highways. We also carried out weekly inspections of super-structure construction.
