    Tapped holes for structural member connection

    Alright I got a project that the vendor is trying to use tapped holes and a thread bolt for all their structural load bearing member connections. Essentially, their members are connecting to HSS tube steel and therefor a nut cannot be attached. Is there a code in California that prohibits this...

    High Pressure RP backflow Device

    The system is for an interconnect between two agencies. The pump is pumping non-domestic well water from agency "A". The recycled water is sourced from another agency agency "B". Agency "B" is requiring an approved certified RP device in order to contain agency "B" contaminants from the recycled...

    High Pressure RP backflow Device

    800 gpm. I have to have the higher pressure in order to pump into an existing pipeline flow direction #1. The water source is non-domestic water as well. Putting in another pump is practically uneconomical.

    High Pressure RP backflow Device

    I have attached a simple P&ID diagram to explain why I can't use a PRV. I agree with your logic but won't work for my application. http://files.engineering.com/getfile.aspx?folder=0d457fe6-9c60-4e44-a159-fefd668eb4ab&file=DOC072015.pdf

    High Pressure RP backflow Device

    I have a situation where I need a Reduce Pressure Principal Backflow Prevention Assembly to meet a maximum operating pressure of 235 psi. The agency standards require a RP not a double check. The problem is most of the common manufacturers all have told me no one makes one rated for that high of...

    Flowrate in a vertical straight up-and-down pipe

    I am confused, Wasn't your original question to determine the direction of flow? I would just start to close the globe valve. If its pressurized system the pressure on the upstream side will increase. If it gravity feed then upstream side could remain the same but down stream side will equalize...

    Using PE for the QSD

    As I stated, I just got done with taking the training and the instructors said you can just bypass the test, same as taking the test just license # & lookup isn't that same. However, the information I read on the sites say using PE's to bypass the test for QSD only in some locations. I guess...

    Using PE for the QSD

    I just finished the QSP/QSD Training. They now allow you to use your CA PE in lieu of taking the QSP & QSD Tests. From the info I have found it just makes your license # available only on the CASQA site and not the other sites, Also, adds a "C" in front of your QSD #. Does anyone have any...

    Spliting of 2x6 joist

    Yea but unfortunately from my understanding in California, only a fully and active licensed engineer can make a structural integrity statement like that in litigation.

    Spliting of 2x6 joist

    dcarr82775, I disagree. The contractor's scope of work on his quote stated remove rotted wood and installed new wood joists to code. I am not going to pay him extra to replace his work that is not to code. By law since he is licensed, he is required to perform diligent work to local building codes.

    Spliting of 2x6 joist

    msquared48, I agree but the contractor nailed the new floor joist to the existing rotted joist all the way down (length wise)so the cracking is continuous from end cap to end cap. My worry is that with this full length cracking any shear force will snap the joists in half. Wouldn't this reduce...

    Spliting of 2x6 joist

    I have a contractor who is replacing a portion of our houses' sill plate due to dry rot of the existing joist. The floor joists are split in the center and some are not even nailed to the sill plate and they are completely missing the rim joists. Contractor stated not his problem. Can some one...

    Heavy Civil Construction Estimating

    bridgebuster- now that is an answer! You are right they are leaving me in the dark. It's rather annoying but fortunately for me I know how to use resources like this forum to learn my self. We do lots of different projects so that's another problem that I understand no one will "exactly" be able...
