RE: Timber Frame Construction Tolerances

[Subject Prev][Subject Next][Thread Prev][Thread Next]

We have a book called the Residential Construction Performance
Guidelines that may be of use to you. It contains a wide variety of
commonly-accepted tolerances and performance measures covering
everything from framing and foundations to finishes and site work. It
was developed primarily by our remodeler and small-volume builder
members as a tool to aid in dispute resolution. It's one of our best
selling books and is often written into residential contracts as the
first go-to source for mediating performance and serviceability issues.

It's available from our Builder Books store:

Subject: Timber Frame Construction Tolerances

I am doing a forensic investigation of a residential floor "failure"
with respect to poor evenness of a floor assembly. I have ascertained
that the structure assembly is sound so it's a serviceability problem.


I have done some relatively careful and accurate levels on the floor
surface and found that over about 30' I found some spots as low as 1.25"
below "0"


The original localized "depression" that was discovered and started this
investigation, we have now successfully mitigated by jacking the floor
joist immediately affected and spliced on new engineered beams.  We have
achieved an evenness across the floor in general but the entire floor is
sloping toward one corner . we conclude that it has been built that way.


I'm looking for code or guideline tolerances for timber framed
Steel has codified or recommended tolerances but I'm not sure that is
applicable to timber construction.


Does anyone have any references or code prescriptions?
