Re: [External] heads up
Colleen,
This email confirms that the ironbridge projects are in climate zone 5 and only 24" of horizontal insulation ís required
The structural plans indicate 4'-0" which may be reduced to 24" per the Garfield county requirements as well as the
2009¡ECC.
Please let me know if you need anything from me moving forward.
Thanks,
Mike Arbaney

Hello Luke,
Just a courtesy heads up on a couple of the lronbridge job sites. This morning Jim Wilson, GarCo building inspector, was
asked by someone at the job site f they could have permission to modify the shallow foundation insulation design for
your proposed building(s)? Are you made aware of this? From cell phone call from Jim, he directed the contractor on
site - f they are to request changes or amendments to the foundation details to obtain the Engíneer of Record's
approval for changes. I am gathering this job site will continue to have 3'd party input or oversight and l'm concerned
whether this new request from the field reflects all parties i.e. (SCIB LLC) owner / owner representative and/or third
party oversight or íntent? Wanted you as owner representatíve to be aware of this.
lf you haven't directed this design change, please collaborate with the 3'd party inspector / engineer of record and
subcontractors to ensure everyone's on the same page with construction moving forward.
