Quick post as at work where we're listening to Radio 4 (well Proj Management are, so we are as well). The reason this radio have entered the workspace is because the series 'Engineering Solutions' is on and it starts with the Spinnaker Tower. It was presented by Adam Hart-Davies (of those Science & History Programmes) who was really good (if scared of the hoist lift .. once you've stepped off it a few times its not as bad). Anyway if you want to hear a really good enthausiastic programme about Engineering (or just interesting structures) it's on 'Listen Again' at Radio 4
