E class vs large settlements are two different issues. For E class you can control the flow of water and moisture around a building with good management practices. There are some pamphlets on this available on this for as2870.

Does this substation have a slab connected to piers?

I would ask for a few holes, we use snake cameras to keep the holes small in size.

This post sound very HR/recruitment, might be better moving this to one of the soft forums.

Presets are a cost effective way to get some dead load deflection control. Presets are created by adjusting the bevel angle of the apex, hanch and splice cuts.

Wind and seismic are different types of loading, generally wind has a service and ultimo drift limit, while seismic has only an ultimate drift limit. Depends on your location and type of building. Check out the info in the FAQ area.

In instances like this, I do homework to see what the contractor has completed previously and what drawings he had access too. Often I find that there is a perfectly acceptable solution, just the builder has no idea how to express the solution in engineering terms. I would ask for a few...

Existing building are a very grey area, and good luck to finding a balance between codes and engineering standards. My question would be used of the building after purchase? if you client intends to convert it front the original use of heavy manufacturing to something different, then in my neck...

Rofail and man's 2003 windtech consultants is an Australian research but maybe of help.

Also depending on what your doing, we could have a wood armer issue.... The list is long.
