Topics/Subject Old Business Decisions/Conclusions/Actions None New Business Sealed Crawl space meeting Continuous Handrail definition NCDOI Website Pier and Curtain wall foundation There is a Department meeting that is scheduled for December in which Jeff Tooley from the Raleigh area will be down to discuss the changing code requirements dealing with sealed crawl space applications and moisture control. Other surrounding Departments will be invited as well as the industry is welcomed to attend. If any builders would like to attend please e-mail Jeff Griffin at [email protected] to RSVP. Meeting is scheduled for Friday December 3rd from 8:00am10:00am. Under the CABO code the Department had a formal interpretation of continuous handrails that was designed to deal mainly with winder tread issues. This interpretation has been re-visited with the new Code. Attached is the new interpretation which will be posted to our website. Please note that the one tread depth rule is for a vertical drop as well. We will try and attached a couple illustrations before posting this interpretation to the web. Currently DOI has posted now 18 formal residential interpretations all of which have been addressed in meetings with no new interpretations affecting field issues. Website is www.ncdoi.com. Issue has come up with the application of bolts at pier and curtain wall foundations. Bolts are being installed too high and on veneer homes the band has to be notched to sit over top of the bolts. In some cases these bands or exterior girders are over notched or not enough bearing left Continuous footer tie in for additions Insulation in slab applications Concrete priority inspections Joint participation with other City/County Inspection Dept. Recap of mending plate for mudsill splices sitting on the pier. Recommend usage of anchor straps at all pier and curtain wall foundations, which will prevent this from being a problem but builders should be aware that exterior girder (double band spanning from pier to pier) cannot be over notched unless there is 3” of bearing left from the bolt notch to the edge of the pier. Question raised about a standard application for room addition that are attached to an existing foundation. The code requires footers to be continuous (R403.1) and typically this is done by dowelling into the side of the house footer at this cold joint. Without the use of epoxy a standard application that has been approved based on engineering is to dowel into the house footer 12” and leave at least 2’ out into the new footer addition. This application is only allowed with standard soil bearing capacity of 2000psf and where addition footer doesn’t require reinforcement steel per design. Concern issued about the installation of perimeter slab insulation that on many sites is not being installed compliant with the code. Table 1102.1 indicates a requirement for zone 7 to be R-4 with a perimeter depth of 2’. Many slab have this insulation (like a mono slab) installed inside the building and doesn’t properly insulation the slab perimeter reference figure E-3 and E-4 as examples on page 556.17 & 556.18 of the Residential Code. If foam insulation is not installed correctly in slab applications then a Res-check is required to verify compliance. Question raised about concrete jobs that are a priority inspection for the department and about communication if inspection cannot be performed during that day. Every attempt will continue to be made to make sure that concrete is a priority and communication, when possible (contractor should leave a call back number), will also take place if inspection is not going to happen that day. A inspection that was not ready when the inspector came through that area is not a priority inspection for that day and contractors are advised to communicate with inspector when they are not ready the morning of, in order to determine if delay of site visit is possible. Questioned asked by builders about involving other Municipalities in joint consistency meetings or training. Many builders build in surrounding jurisdictions. Efforts have been made to invite surrounding Municipalities to training sessions or even consistency meetings. The December 3rd sealed crawl space meeting is an example where other jurisdictions have been invited. DOI had a interpretation where the top plate mending plate for a more than 50% notch per section R602.6.1 could be used to nail across mudsill splice so that bolts would not be required on either side of the splice and only the required spacing of the bolts would be a issue. This 1 ½”x18” 16 gage plate with 6-16d nails on either side of the splice can be used on the mudsill on the interior side where a wall to foundation or slab connection is made. This is good only if the exterior wall sheathing is structural at splice as well, like plywood or fiberboard, if it is foam Frame dried in requirement then another strap is required on the exterior. Please note also per previous discussion that the application of this mending metal plate is not required on splices to mudsills on foundation walls that have a floor diaphragm system setting on it like a crawl space application. Question asked about what was required for frame check to be considered dried in. According to the NC Administrative and Enforcement requirements Code section 306.6 the permanent roof covering does not have to be installed in order to get a frame inspection. Permanent roof covering is required by insulation inspection but at frame only the felt paper needs to be installed properly. Please note that PVC boot collars should be on roof and no daylight openings light ridge vent already cut out. Next meeting is on December 1st in Woods conference room at 8:00am, 700 N. Tryon St.
