Richard:

I halfway agree with you.  The Residential Wind Load Design Technician Certificate is to be used by contractors for their own projects.  Period.  But nowhere do I see that it requires that certificate to design using IBHS.  In fact for SINGLE FAMILY RESIDENTIAL I see no place in the FBC or state statutes that says the building requires any Design Professional (except for over 600amp electrical) or a WLDTC.  The WLTDC is there to prove to the plans reviewer that the contractor is capable of designing to that standard and therefore is to treat the plans the same as if signed by a DP.  However if the design is by IBHS without the certificate then the plans reviewer is supposed to double check the design.   

Sarasota county has been doing this for longer than I've been drawing plans (13 years) and it works well because they make sure that the plans reviewers and inspectors understand the SSTD/IBHS scope and methodology.    

jmho,

  Let's see where the following might lead us........If the contractor is required by law to prove he or she competent by taking a 3 day course and pass an examination to be certified as a Residential Wind Load Design Technician, design without an engineer. Please someone explain to me how a Plan Reviewer could review said plans and worksheets without proof of same competence? Yes, the Coastal Construction exam and certificate is the closest I know of. To hold the Single Family Plans Examiner license part of the criteria is the Coastal Construction exam STDD1099/IBHS. I have often wondered why the Plan Examiner is not held to the same standard as the Contractor in this case. For those who doubt this design method; STDD1099/IBHS/ICC-600 was written by engineers, therefore the design is deemed engineered.

  One further note: The Residential Wind Load Design Technician Certificate is only to be used by a Contractor to design and build his or her own projects. The method is not available to anyone other than contractors in the design effort for commercial use. Simply stated; a designer may not use the method without professional review. But, methods employed within the standards have valuable information to meet the windload  requirement. A very handy tool for a designer.

  A follow up question: Will the 2010 FBCR site the new ICC 600-2008 American National Standard? It is an upgraded IBHS.

    Greg:
    Actually he did ask what was the current design standard.  I've talked to more than one contractor that hasn't permitted a new house in several years and they look to people like you and me to help get them back up to speed.  I think that if he gets the IBHS book (which he needs to do) and uses the worksheets that he would be able to catch the changes.  

    Hopefully he permits someplace where the plans reviewers understand IBHS like you guys do.  I've done plans in jurisdictions where they had little or no understanding of the SSTD/IBHS series.

    later,
    glen

       My concern is that it would appear the only information he is asking for is what to write on the cover page to apply for a permit. He will not be able to prepare drawings or construct the home correctly without reading and understanding the requirements of the prescriptive method. No mention of what might be the major changes etc from 10-99. I would feel more comfortable if he was asking does anyone know where I could purchase a copy OR I have a copy of the IBHS and I have a few questions about.

        I have done my own drawings on a bunch of homes prior to the housing bust, and they were all designed by 1099 standards and language. I have not done one since the codes have changed. Can anyone help me with what the current design standard and necessary language that is required on the cover page of the drawings. The project I have coming up is residential and not on a barrier island, and I want to do Contractor sealed drawings.
