When this comes round again

Science Museum Group publishes Construction work continuously — 159 notices, roughly one every 15 days. This is a stream to watch, not a cycle to wait for.

40% of Science Museum Group’s awards go to a supplier it has used before.

Which is the argument for getting on the list rather than winning this one. The incumbent is rarely the last winner — it is the roster. See the retention odds by category →
