thread732-193252 there are a few others too so do a search.
At my last job I had phases where I seemed to spend all my time on project managemant (as in paperwork, not leading th project), bid preparation etc. As you say it can be boring and monotonous. The full contract on one of these that I'd spent time on off & on didn't even get awarded till I left the place, so I didnt' even really get to work on it (however, it's now proudly displayed on the cover of this weeks air forces monthly). In fact that company, at least the department I was in, has grown massively.
Battle through it and do the best job you can. For me things would normally come up before I completely lost interest/the will to live. Or on one occastion they gave me a big pay raise (off the regular schedule) just as I reached the end of my tether.
I got a lot of credit for doing all that dull admin stuff & doing it well (or at least adequately/better than most of my colleagues), maybe you will too.
If if really looks like there wont be any work then start looking for alternative employment (it's rarely a bad idea to be at least half heartedly looking anyway, even if you have no big plans to leave any time soon).
I did used to find small design tasks to do on the side to keep me sane, any chance you can do anything like this?
KENAT, probably the least qualified checker you'll ever meet...
