Chalk Hill Youth & Community Centre
The project was a design and build contract which included the part demolition of the existing structure, retention and refurbishment of an existing gymnasium building, construction of a new two storey office and classroom block, new single storey multi purpose hall and rebuilt single storey Café area for Brent Council. jnpgroup consulting engineers formed part of the design and build team that were awarded the contract and services provided included the design and detail of foundations, substructure, superstructure and drainage.
The Site
The site is located at the end of a residential estate with the proposed buildings to be constructed over the footprint of the demolished structure and previous asphalt hard surfaces in close proximity to the river Brent. The site was slightly sloped, falling from north to south towards the river which is aligned with mature tree’s. and was to be securely fenced off from the surrounding residential buildings
Project Value: £?M
Client: LB Brente
Architect: TPA Studio Architects
The Design
The building is provided with a specialist Kalzip standing seam insulated built up roof system to suit the barrel vaulted roof’s, supported by cold rolled purlins on profiled steel frame’s jnpgroup consulting engineers used specialist software to design and model the barrel vaulted steel frames and cold rolled purlins, working in association with the roofing specialist and steel fabricator.
The two storey classroom block was provided with a steel frame at first floor level only with insulated cladding panels forming the external perimeter walls. and jnpgroup consulting engineers worked in association with the specialist cladding contractor and precast concrete flooring company to assess the frame and accommodate the column loadings at first floor level, which were complicated by first floor cantilevers at each end of the building. Jnpgroup were also responsible for the design of the loadbearing masonry structures which supported the upper floor levels including an overall stability check. Access to the first floor is via a disabled access lift by specialists and a concrete infilled steel staircase designed by jnpgroup inaccordance with the steel fabricator. The ground floor construction was of traditional loadbearing masonry, which was designed to suit the precast flooring and steel frame loadings
The single storey multi purpose hall was provided with a steel frame to support the barrel vaulted roof structure, built into masonry walling.
jnpgroup consulting engineers were also responsible for the design of the loadbearing masonry structures which supported the upper floor levels including an overall stability check.
jnpgroup consulting engineers designed the foundations to accord with NHBC design guidelines for building near trees in clay soils, assessing the impact on the retained buildings and strengthening the foundations accordingly by underpinning where necessary
jnpgroup consulting engineers were charged with designing the new foul and surface water drainage infrastructure, to establish the most direct and economic solution for discharge of the foul and surface water from the new building via the existing drainage infrastructure, into existing Thames Water sewers and the adjacent river
