Purlin has a crack/split. Big job? Surely not??

I’m getting rinsed next week. Clearly.

You do not need to be. You have plenty of time to tackle it yourself. Get a 1m x width of joist piece of cardboard. Mark it up with around 24 positions for holes, evenly spaced, 12mm. Find a local engineering company which can cut the steel, 8mm thick and drill the holes, explain what it's for, and ask them to quote you to make it up.

Get some 10mm threaded rod, 48 nuts and washers, plus a dozen 10mm shank coach bolts. Assuming you have a drill - drill pilot hole to accept the coach bolts, then gradually tighten the coach bolts, a little at a time, over a few weeks, until the plate pulls the timber flat. Your final job, is to remove the coach bolts, one at a time, drill the timber through 10mm clear, fit and tighten the threaded rod, nuts washers and bolts.

Sounds like a good plan.
One thing I am thinking is would that size split actually pull together. I see you suggest doing it over weeks though.

I would expect it to, if done gradually.
