Was hoping I could get some advise on the following…
Please see attached images to assist in understanding the situation.
Existing building from the 1920’s. Looking at having considerable work done to the front (East Elevation) facade (and more minor tuckpointing on the sides.
As well as replacing the entrance, I am also having the lintels (and one sill) replaced. Masonry is not my area of expertise, and would like to be as informed as possible for conversing with the contractors, etc.
My question has to do with the replacement of the large lintels over the windows (8’-10" span). Currently I have had two proposals and both are recommending replacing with a steel lintel and three new sections of limestone in lieu of the single limestone. Reasons for this are it is more cost effective as the larger limestone pieces are very considerably more expensive as well as infinitely more difficult to install in a ‘retrofit’ type installation.
We are anticipating installing such that the new limestone pieces line up with the window mullions (for aesthetics).
For this application:
(a) would I be correct in thinking that steel would/should be installed with the horizontal section of the steel at the top of the window, with the vertical part of the steel rising up? And that then the new limestone pieces would be installed above that?
(b) If that is the case, would it be sufficient to have weep holes at the seams of those new limestone pieces? It seems that the section over the middle window might need a weep hole in the middle, but I don’t know how that would be accomplished with not having a mortar joint location in the middle.
Any insight would be appreciated.
