Tonbane delivered a 420k external works package at Imperial College for Graham, covering excavation to formation, drainage, sub base, granite setts and paving. Excavation, drainage, reinforced concrete, basements and external works in South Kensington for developers and main contractors.

Much of South Kensington sits inside a conservation area, so excavation and external works there run under tighter constraints on hours, hoarding and the finished surface than they would a mile down the road.

Much of South Kensington sits inside a conservation area, so excavation and external works there run under tighter constraints on hours, hoarding and the finished surface than they would a mile down the road. Every package is priced off drawings and a programme rather than guessed at over the phone.
No. South Kensington is roughly 6 miles from the Ealing base, well inside the daily patch, so travel sits inside the package price and a site visit is normally quick to arrange.
Tonbane delivered a 420k external works package at Imperial College for Graham, covering excavation to formation, drainage, sub base, granite setts and paving. If your scheme is near Imperial College, send the drawings across and we will tell you what the ground and the access there normally mean for the dig before anyone prices it.
Yes, and in South Kensington it usually changes the setup more than the structure. Conservation control tends to mean restricted working hours, hoarding that has to look presentable, and a finished external surface specified to match what is already there, so the programme allows for it rather than discovering it at week three.
Yes, and that is the usual reason a main contractor calls us rather than three separate subcontractors. Excavation, temporary works, underground drainage, reinforcement, formwork and the pour are all delivered by the same outfit in South Kensington, so the interfaces between them are ours to manage instead of yours.
South Kensington is about 6 miles from the Ealing base, so a visit to walk the site and take the drawings away is quick to arrange. Actually starting on site depends on the current contracts, and we would rather give you a real date against your programme than an optimistic one.
