    Estimating help

    After 13 years of doing this, I'm being asked more and more to provide cost estimates on projects, but have no background in doing so. For designed projects I can easily calculate volumes of concrete, tonnage of steel, and then call producers for prices. What do I do for new construction...

    Live load reduction on a transfer girder

    I have a transfer girder that is supporting 4 floors of load-bearing walls. It seems to me that this still would still be something that we could reduce the live loads on, but how should we consider the Area that this transfer girder is supporting for the reduction calculation? Say for example...

    Incorporating a drafter into Revit workflow

    In all of my past Reviting, I have done all of the modeling, detailing, and document production. The drafters we had at my old job were treated as line tracers and not given much opportunity. I have recently switched jobs to lead a building-structural department "inside" of the existing...

    FEMA 361 - debris impact on concrete over metal deck

    I'm looking for a little insight here since my searching is coming up empty. Looking at FEMA P-361, 7.3.5 it says: If I consider a steel deck acting as the form with 4" of reinforced concrete over top, I have always been under the impression that this complies with the missile impact...

    Help with notation on existing drawings

    I am looking at a set of existing drawings dated 1974. The steel beams have a "SC ##" designation on them that you can see in the photo. Any thoughts as to what this is? Shear studs? The existing details don't show anything out of the ordinary graphically at least. Thanks for any help. I...

    Horizontally Spanning CMU and vert control joints

    I searched the forums and nothing came up, so I apologize if this has been asked. I have a tall CMU wall that spans horizontally 12' to pilasters. Wall lengths are in the neighborhood of 116' each. The wall works spanning horizontally and the pilasters work vertically. My question is about the...
