Minor Renovation

My house has been undersgoing some minor renovation recently.  The contractor has stopped half-way citing that some certain stock was inadequate and he is waiting for the products to arrive.  This left me in the lurch, I would rather he finishes the renovation at "one go" so that I can tidy up the house once and for all.  My balcony is in a mess due to some "leftovers".. some metals stuff and they reminded me of the u-bolts in this website.  I hope the contractor will be able to finish before end of this month, I really don't like to see my house in a mess and it is very tedious to clean up again and again...
