can't help without some further info.
 
Can anyone help I'm having trouble trying to work out ib for a lot of these circuits in here any help would be appreciated

I finished it a couple of weeks ago. First you should divide your installation into final circuits. Use the drawings, think about the wiring systems you want to use, remember that the offices and the industrial side of the installation will require different wiring systems. When you have the list of all final circuits start asking yourself: are the loads inductive or resistive? For example the cooker is purely resistive, discharge lighting is inductive. What kind of MCB should you use? Open On-Site Guide, Appendix A, and read everything. The problem is that the installation is has a three-phase supply, so you should start thinking about how to balance the loads across the three phases. You should also think about how to allow for diversity. It looks convenient, in this case, to apply diversity to groups of circuits, rather than individual circuits. Maybe you should apply diversity according to OSG Table A2 for the offices, and ignore diversity for the industrial area.
 
Is this the office/workshop install for the highway depot? As above its all down to your individual installation design, I could send you all my work from when I done it last year but it'd be wrong for your design, best thing to do is to sit down with one of your college mates over a few beers and put your stuff together. Both your install designs 'should' be different but the theory will remain the same. I used the unite guide little green book, make sure you quote where you get your figures from, iirc our tutor used to like us to put where we got our points of reference from.
