RE: shoring lagging remove or remain?

[Subject Prev][Subject Next][Thread Prev][Thread Next]
97 UBC 2306 requires "structural" wood that is embedded the ground to be treated.  The UBC reasoning is to prevent the structure from being damaged.  CABO 323 has methods of termite control for below grade "structural" wood.  I would think you could permeate the stuff with treatment or poison the soil next to building to prevent bugs from finding the wood inviting. 
 
If I was your building official [or designer] and there was a local termite or carpenter ant problem, there is no way on God's green earth that I would let a contractor save some money by leaving a little food cache for a termite colony next to someones house, old folks home or kindergarten.  I will stop here before I start to get sarcastic.

Subject: shoring lagging remove or remain?

I thought I sent this before, but can't find any record of it being posted. This is a new version of the same question, pardon the duplication.
 
 
A building official is looking into having our wood lagging removed before we backfill for pest infestation reasons. The shoring wall is 2'-6" in front of our permanent concrete retaining wall and  building envelope above (wood framed residence). The earth shoring wall is at least 16' tall with pressure treated lagging, not treated at the cut ends. I could see removing the top 3-5 feet. I could not find anything in the code specific to this?
