Truss calculation missing in county records

4 years ago

We had our Roof, Truss, Nailing inspection and the inspector disapproved with comments that "city approved truss calculations were not present onsite".

I tried to get info from my GC and he said somehow inspector couldn't find truss calculation in system.

When we submitted our architectural plans, truss calculation was a deffered submittal and explained this to GC. I thought either him or the truss company will submit these calculations.

Questions :

1. Is it possible truss company build trusses without even getting the approval from city ?

2. Now that the roof is already built without truss calculation approval, what are the risks. Is it possible city might reject the whole truss package and contractor has to remove and rebuild whole roof again ?

3. Generally how long it takes for truss calculation approval (We are in santa clara county unincorporated area).


Thanks.

    1. Yes.


    2. Yes, but unlikely.


    3. No idea.

    "I thought either him or the truss company will submit these calculations"


    Whose name is the permit in? Who submitted the drawings?

    The inspector's comments indicated that the truss calcs were not present on site. The municipalities in which we work require copies of all approved plans and supporting documents bear the "Approved Site Copy" stamp from the municipality and that they be available for the inspector on site when an inspection is performed. If they aren't, the inspector rejects the inspection and the municipality charges us a reinspection fee.

    If the calculations were required in order for plan approval, a permit should not have been issued without them. It could have slipped through the cracks, or it may simply be that the paper copies weren't on site at the time of the inspection. Don't panic.

    It is unlikely that trusses were improperly designed. It is more likely that the contractor has not installed all of the bracing required by and shown on the design drawings: especially if the drawings weren't on site.

    Thanks everyone. The permit is on our name (as owner builder) and it was issued as a deffered submittal for truss calculations.

    If you're an owner-builder why did you mention a GC in your post?

    So, why didn’t you submit the calcs? That, and being there and bearing the brunt of the inspection requirements, is literally your job as the permit holder and GC of record. That is what being an owner builder is all about. You are tespinsible for all of the details, even if you dont understand tgat you are. You. Not your employee. Who you better have covered with workman’s comp insurance, in addition to your general liability and builder’s risk policies.

    The permit is on our name but we do have a GC taking care of the project

    I don't know what advantage your contract arrangement provides you as the owner. In the municipalities in which we work, the owner, if they hold the permit, is accountable to the municipality for constructing the home in a manner that meets code requirements. That may put you on the hook to correct deficiencies at your expense.

    You cannot hold anyone else to be the responsible party for the build. That is literally what an owner builder does. Even if you hire a construction manager, they are your employee as the builder of record.

    And if you do not have the correct insurances to do this, you are risking losng it all in a lawsuit, as you are personally responsible for the site, and any issues that arise. Including failing inspection. All of that is you, and your money to pay for any reinspection or remedy to the issue.

    If you do not want to be responsible, too bad, and too late. That is the path you chose. You get sll the headaches, not just the fun title. You cannot shirk that responsibility. Your name is on the permit.

    Call the truss manufacturer, have them reissue to you the calculations package. Submit them for permit. Once approved and returned, keep them on site. All you, since permit is in your name. While you are awaiting that review process, verify with inspector what work can continue that won't interfere with their reinspection.

    Thanks 3onthetree. I am reaching out to truss company to get the copy of calculations.

    Not a huge deal, but your responsibility if you employed the truss company.

    1. Truss co supplies you stamped calcs
    2. Your engineer of record reviews and provides a letter (likely required)
    3. Building department reviews & approves
    4. reinspection called w docs on site

    Thanks Jeffery. The engineer of record implies structural engineer ?

    We don't use many roof trusses, but the truss company takes care of getting the plans sealed by a licensed professional engineer. Your "GC" should know what typical practice is in your area.


    For anyone whose "contractor" asks them to pull a permit, it may be because they don't have a contractor's license. Caveat emptor.

    If the owners obtain the permit they act as the contractor and are
    responsible for completing the work and to assure that it meets code
    requirements. Interaction then takes place between Building Division
    inspectors and the owner. If the owner has hired a contractor or other
    person to do some of the work and it is not done in accordance with the
    approved plans and code requirements, the inspector will ask the owner,
    not the contractor, to have the work redone. In other words, if the owner
    obtains the permit
    it is the owner's responsibility to make sure the work is
    being done in accordance with the approved plans and codes.


    You choose this contractor, why?

    Thanks everyone for your feedbacks. We pulled the permit on our name initially because we haven't finalized the contractor at that time and we need to submit a revision for some changes and county's rule was we need to pull the initial permit and then only we can submit the revision. Our approved revision permit is pulled by our GC. The truss calc submittal somehow fell through the cracks due to some confusion between GC and truss company and the GC is on it now. Again thanks everyone for your feedbacks.

    The locality's permitting process seems a bit convoluted--at least on this project. I suspect they'll be lots more "educational opportunities" as the project progresses.

    We got the stamped calculations from the truss company. Also as I mentioned earlier, the permit is on our contractor name who is licensed.
    We sent the stamped calculations to structural engineer and after reviewing he found there are two trusses which shows interior support in truss design but they were supposed to be designed with end bearing only and he asked to revise the design. Does changing from interior bearing to end bearing implies we need to get a new truss and replace the existing one with new truss ?

    You'll have to notify the truss company. They may be able to field modify the truss that's already installed.

    This happens & why engineer reviews. (not always caught by reviewer or inspector but critical to get right).


    Typical options (worked out between engineer and truss designer):

    1. The two trusses get changed IF its possible for them to make the span

    2. A beam is added to replace or strengthen truss

    3. Bearing is added under the point where the engineer shows it is needed, hopefully its a wall with some foundation under it or can be added.

    Thanks Seabornman and Jeffrey for your responses. Do you know if there are any third party truss experts which can review the truss work done onsite. I just want to make sure when all the work is done, someone can review it and make sure its done correctly. I asked the structural engineer and he said he doesn't review the truss work done onsite and I am not sure if city inspection is detailed enough to catch any flaws.
