You're in Las Vegas,you'll need
to look up "historic preservation."

So $40k per column sound right for replacing those columns?

Could be, if he has to stay
within historically correct materials
and preserve as much original
as possible.
It is cheaper to just tear
down and start anew many times,
but not if the idea is to presreve.
I was joking about the way they
constantly tear down and rebuild
out there.
Not much left of the town I knew
in the 50's and 60's.

Neo.... tear down is always more expensive, in the historical context that you lose. OP, give me a call, I'll consult for your project.

Sorry JW,

I haven't been watching my thread as much as needed.

The HO is away, (archeologist) he is out of the country for 2 months.

I will be doing the work myself. It's still a point of getting to talk to him again.

Will keep you all updated on the status!

I hear yah. They are tearing something down then building something new. If not that. They are remodeling something. Well that was before the economy took a ****.

We lived in a house similar to this [see attachment.] We had similar rot on the bottom of our columns. We jacked up each column and replaced each stave that was rotten. We staggered each one to provide additional strength. Another product that I learned about that is invaluable for old historical home repair is a product called Abatron. This is a FABULOUS product. I would not replace the columns but instead would repair them -- not a big deal.

I would also recommend getting the Abatron Liquid Wood Epoxy. The capitals on these columns are expensive and need protection from the elements. We stripped ours with a torch and picked out all of the paint the painted this epoxy onto the top of each capital. This will ensure no further deterioration.

In my professional opinion; you "can not" remove an 18" section of the column shaft and enlarge the height of that base ,ie; large square base. That will change the architectural order of the elements in the Corinthian order and would not be professional as far as I am concerned. Aesthetically this will not look proportionate and of the true order in Corinthian architecture. The plinth base should not exceed 1/6th the diameter of the of the column in Corinthian order. As far as the true order it could be the composite order (can't tell from the photo) on that part the Volutes would be replaced by large scrolls,echinus and astragal, but again I can't tell from the photo- I think it's Corinthian. Either way the scale fallows the similar order of the vignola. But the plinth base photo is of the Doric order.
Without getting caught up in terminology- if you take the column length ,divide that into sixths- 1 sixth of that you can use for the new "pedestal base" which is still acceptable in all orders of the Vignola , but again this is not a Square base -your plinth " base" will still remain- but will need additions on dimension ,ie; squared width. Think of it as a wider shorter column sitting underneath the main column. if it is a 30' column-which it is not , just does not look like 30' - you are looking at around 20' (10' 1st floor - 8' 2nd floor) not including the Corinthian capital or the entablature - just the shaft (column) that would be 3'-3- 3/16" in height - but you need an accurate measurement on the column in order to get the dimensions for the pedestal. - The bottom of the pedestal (resting on the base ) will have a Palladio's Corinthian base - the pedestal - that can have either stop flutes as you have shown in the bottom of the shaft column or smooth flat surface- but usually they run identical, so it should be stop fluted to match the original dimensions of the column and order. The upper part of the pedestal should have a return design as what is on the bottom of the pedestal only facing it's mate (upside down) Palladio's trim . This can be done and has been done successfully with out changing the definitions of the architecture implemented in and on the building. You would be doing this "without" removing or disturbing the columns, capitals and entabliture - I have a lot of useful information for you on tackling this. It is a staved construction you are dealing with (obviously) and repairing that is just surface repair ,you have structural elements of this that you are dealing with but is can be repaired better than what is there.
