(Portland, OR)  --  It will cost a lot more to renovate the Portland Building than originally thought.  The "Oregonian" reports the new estimate for Portland's administrative headquarters is now 175-million-dollars, nearly double the original estimate of 95-point-four-million-dollars.  The renovations are designed to correct seismic deficiencies and repair water damage.  The new estimate comes after Portland's top administrator recommended gutting the Portland Building, renovating its interior and replacing nearly all of its mechanical, electrical and plumbing systems.
