Dry dock

[Waterworks]

What would be the cost estimates for building a 80 ft x 30ft concrete canal dry dock ?

£200-£500k

 

That's assuming 250mm thick reinforced concrete. Allow about £1k per m2. No allowance for drainage, edge protection, access, egress etc.

Excavation costs come down to access and muck-away, obvious proximity to water means constant pumping until concrete is water tight. But your “big” item here is the coffer dam to hold the canal away while you finish the approach and gate etc. CRT (canal river trust) can be a pain to work with on something like this.

i would be erring towards the upper end of @Conor estimate
