A sample answer to question 1

What is the difference between first fix and second fix carpentry, and what jobs fall under each?

First fix is the structural and rough carpentry carried out before plastering, and it is largely hidden afterwards. That includes floor joists, stud partitions, roof timbers, noggins, stair strings and carcassing, and fitting door linings and window boards before the walls are finished. It needs to be accurate in position, because the electricians and plumbers follow with their first fix, running cables and pipes through the timber, so I make sure notches and holes are within the permitted zones. Second fix comes after plastering and decoration preparation, and it is the finishing work: hanging doors, fitting architraves, skirting boards, stair balustrades, fitted wardrobes and kitchens, and ironmongery. It is visible, so the standard of finish is crucial, with tight mitres, neat scribing and no hammer marks. I check my first-fix work against drawings and levels so the second fix runs smoothly.

Common mistake to avoid: Mixing up the stages; ignoring coordination with other trades
