    Testing Tension Bolts

    In our case these are TC bolts and have to be inspected by the special inspector by testing a representative sample The RCSC reads: "7.2. Required Testing: A representative sample of not fewer than three complete fastener assemblies of each combination of diameter, length, grade and lot to be...

    Testing Tension Bolts

    To clarify, it is a job site not a manufacturing facility. The inspection is prior to installation once we receive the bolts on site.

    Testing Tension Bolts

    The special inspector said that he has to test 5-bolts from every lot and that three of which ONLY has to pass. These are A325 tension bolts. The 60% passing seems very high to me. What do you think?

    Bearing Capacity of 95% compacted fill

Moist. is 7.1, SP.G. 2.65, LL 35, PI NP, %>3/8 in. is 4.1 and % < No.200 is 12.6 What do you think? And thanks a...

    Bearing Capacity of 95% compacted fill

    We need to place a spread footing on a 95% compacted fill. The EOR requires 5000 psf. I am getting conflicted information. One of which that with 95% compacted you cannot reach 5000 psf; the other is that you cannot use DCP to verify that; and 95% automatically gives you the 5000 psf. HELP please?

    Risk Management Plan for Masonry Construction

    I appreciate all. dhenger: Let me give you an example from the same job on another trade. The concrete contractor had a cold joint in a 20' high wall.

    Risk Management Plan for Masonry Construction

    The Army Corp of Engineers EM-385 looks like safety issues. I am looking for mistakes that needs corrective actions. Two folds for risk management, one is to identify the problem that could happen after you do all the precautions, and how to remedy it should it happen. For example the mortar...

    Risk Management Plan for Masonry Construction

    I have been assigned as a PM to a construction job that has a lot of special reinforced masonry walls. In our preparatory meeting with the masonry guys, I asked for their risk management plan. I got a blank expression from all. Then I simplified by asking for a list of items that could go wrong...

    Do Roof diaphragm and ceiling diaphragm work together?

    In a one story wood frame building in a high wind area, is it acceptable to assume that the ceiling diaphragm and the roof diaphragm work together? and therefore add their plf values together.

    How would solid wood joist looks when it fails

    I did a structural inspection on a 112-year old row house in DC. The property has 2x10 floor joists that deflected about 3-inch (12 - feet span.) The joists show no damage to the fiber. Two questions: 1- When would you say that you have a structural failure for solid wood joists? and does anyone...
