Yes they are indeed the blueprints as published in the Radio Times special ( I still have mine) but be warned they were very inaccurate and indeed the plans for the base section were wrong and anyone attempting to build one had to change the sizes, angles ete.

Spoiler
Maybe not ....... extract taken from the newly published 'The Brilliant Book of Doctor Who', Moffat says:
"The fact is, we're not going to lose the old Daleks [design]. We're keeping them. They're coming back. We'll just use them all at once, and have different ranks. All I've done is give the Daleks an officer class"
Something of a back-track, but I'm not complaining seeing as the new design is utter gash.
There's a very large thread on this on the Gallifrey Base messageboard.
