Remedial project for luxury residential basement project with following extensions to the super-structure.
By an existing contractor, we were asked to look at a project to give a second opinion on the design for a client’s reinforced concrete basement that would house a turntable so they could turn their cars within the confined space.
Waterproofing – We proposed that the composite floor slab was replaced with a reinforced concrete slab. Because we are experienced with basements, we understood that the suppliers of the specialist waterproofing material would not work with the original concrete floor slab solution. The contractor and client agreed that this solution would be a more appropriate better detail.
Temporary works – The original proposed scheme had overlooked a safe way of installing the retaining wall, having considered it a contractor’s detail. SWJ considered three or four different schemes and following meetings with contractors, builders and the ground workers – we settled on a scheme with temporary piles and a series of steel beams to hold up the existing house.
The contractors were then able to install a new 3m high concrete retaining wall. Once the basement was complete, we were able to tackle the challenges of the garden room that needed stability but without compromising the architect’s aesthetics for the mainly glazed room.
