I am in need of a creative (or standard) way of putting up a partition wall in my basement to close it off from the garage.
The problem is that I have plumbing, water lines, and duct work that run under or below the floor joists; leaving me no place to nail a top plate to.
The lowest point in the basement is the duct work, which is about 7 feet from duct to floor.
Is it proper to construct a partition wall 7 feet high where it will meet with the lowest point (duct work) and then hang nailing blocks from the joists to the top plate where possible?
I want to put a suspended ceiling in after the wall is up to hide the plumbing and duct work.
Any suggestions would be appreciated.

 

Can you build a soffit around the plumbing, and then build the wall up to the bottom of the soffit?

 

If the wall runs with the duct.isnt it next to a beam all the way. cant you put the wall under the beam and come back form it to box the duct?????

Thank you for your replies..to answer the questions about the duct work.
The plumbing (PVC), water pipes, and duct work all run parallel iwth the joists but they will be perpendicular to the partition wall. the Duct work is at the point of where I want the wall to end, so yes a soffit could be built there but only the end of the top plate could be secured there (like 12 or so inches).
The water pipes and toilet pipes are in the center of where the wall will be and actually one of the plumbing pipes will run diagonal across where the top plate of the wall will be.
This sounds pretty confusing I know...If there was a way to put a picture of the area I'm talking about on here that would be great...if your curiosity is really up send me an email to Edgecon@aol.com and I will send a digital pic of this nasty problem
Thanks again for any help.
