´´Hayırlı işlee (name) abi´´    and    ´´artık o arkadaki bina yok gencler´´    and i want to ask ..what is this ´´ya´´ that turkish at the first or at the end of their sentences sometimes... what does it mean??

My try as a learner

Good work(name) big brother ...............  there are no more teenagers at back of the building

Wait for native to correct

http://www.turkishclass.com/forumTitle_45813 - heres some info on ´ya´ hope it helps 

I think "Hayırlı işler" shouldn´t be translated as "good work". Good work to me means, "You did a good job out there" or something (correct me if wrong) but "hayırlı işler" is a wish, something like "may you have a nice/productive work day".

"artık o arkadaki bina yok gençler" =  That building in the back doesn´t exists anymore, boys. (Gençler = (lit. youngsters, youths) slang, used when addressing a group of young people. Doesn´t have gender but the closest thing I could think of was "boys")

Uffff ya! wrong again 

Thanks for correcting me yersu 

thanks to both of u and the link is very helpfull.. thanksssss!!
