    AWWA D100-11 Radiograph Test Location Interpretation

    I agree. So, the question is though, let's say you have a tank with 800 lf of welding, so you need 1 test in the first 10' of weld and then 1 per each 100' thereafter - can the 8 additional tests be taken anywhere? Like in the bottom 8' of the tank, or do the tests need to be 1 within each...

    AWWA D100-11 Radiograph Test Location Interpretation

    So, do you mean that the first test should be taken as soon as possible, but tests would still need to be performed as work progresses (1 per 100 LF of weld), or do you read it as all of the tests can be performed at that first level of scaffolding or below?

    AWWA D100-11 Radiograph Test Location Interpretation

    Hi All, looking for some assistance in interpreting AWWA D100-11 as far as how many radiographic tests are to be performed and in what locations. We have two water tanks, each with a diameter of 37'. The tank is comprised of 5 bands with full-pen welds at the seams between the bands and also at...

    Placement of Anchor Bolts

    Try this line, 'it's standard practice for engineers to reject any work that doesn't meet our specifications so you're going to have to remove and replace'. I've done it. The look in response is priceless. I say we start a campaign to make THAT standard practice.

    Surcharge Pressure on Retaining Walls - 2

    AASHTO Standard Specifications for Highway Bridges has a criteria. They say if load is within one-half the height of the wall (measured horizontally away from the wall), to include the surcharge.

    Looking for a particular stream restoration detail (grade control)

    Look for anything Rosgen has written. Here's a link: http://www.wildlandhydrology.com/assets/cross-vane.pdf Details are included, though not truly construction details, but at least something you can work with.

    Code Accepted Chairs for Foundations on Grade

    Hi, Please help! I know contractors are not supposed to use rebar resting on the ground to support rebar - for all the obvious reasons... but, I've tried to find what code or where this is specifically stated and I can't find it. Some posts on these forums say it's CRSI, another post...

    is any one knows the property of an old steel beam 10B23.5 ?

    Visit this site and download the shapes database. It provides all the properties of historic beams/shapes: http://www.aisc.org/content.aspx?id=2868

    Principal Stess?

    I suspect you would want to use an interaction formula where the sum of the ratios of actual stress to allowable stress must be less than or equal to 1.

    Leaving OSB Concrete Forms in Place?

    Any thoughts, opinions, pros or cons on leaving OSB concrete forms in place for concrete footings that will be backfilled (sides and tops)?

    Estimating a fee for the foundation of a PEMB

    Actually, the contractor 'designed' his own floor slab. So, in that case, I said that we would not use hair pins (since we have no control over the design of the slab). So, I would design the piers and footings to resist the lateral force. Yes, that was my thought... $2500 seems like a drafting...

    Estimating a fee for the foundation of a PEMB

    Our fee estimate was in the range of $6k. The contractor told us he could easily have another engineer design it for $1500, but was willing to pay 'as much as $2,500' if we wanted to do it. That sounds like a drafting fee to me, no engineering, no anchor bolt designs, no recognition of the...

    Estimating a fee for the foundation of a PEMB

    "One more thing, Are you then the engineer of record? The PEMB manufacturer won't be." "again, if it's only a PEMB (no add on's like a mezzanine, or firewalls, etc) i state that i'm EOR for everything below bottom of base plate." - yes, this is what we do as well.

    Estimating a fee for the foundation of a PEMB

    How many cents?! wow... maybe we are getting carried away on these. Do you design the length of the anchor bolts as well according to App. D?

    Estimating a fee for the foundation of a PEMB

    yes, yes, I understand. I guess I'm asking more of what do others feel would be a reasonable fee or better yet, a reasonable amount of hours for engineering, drafting, project management, QA/QC? PEMB's are getting to be so common and the construction outfits shop the heck out of foundation...

    Estimating a fee for the foundation of a PEMB

    How do you all estimate the fee for a foundation design for a pre-engineered building? For example, I have a pre-engineered building which is actually an addition adjacent to an existing building. The building is a total of 8200sf. It has 3 different framing configurations with two of those...

    Fence Pole Embedded in Concrete

    Ok, this is my first post, I'm a liiittle nervous! Can anyone please point me in the direction of 'how to' or a reference for the following - I have a fence on top of a concrete wall. We calculated the required Sx of the post based on the wind, etc. Now we have to determine the post embedment...
