    Hate my job

    1) I am a civil engineer in California. 2) I have been looking for employment elsewhere, for over 3 months. 3) An across the board pay-cut was instituted at my current employment. 4) I took this job when I was laid-off due to lack of work in 2009, when construction froze up. It did not pay...

    odd plan scale

    Most of the plans I see now are on 11x17 sized paper, occasionally, but more and more, I am seeing plans at nonstandard "engineering" scales. It seems like it would be convenient if I had a ruler that had 1:8 and 1:16. Does such a scale exist?...If so where can I purchase it? 1) I know an...

    Joint Seals (compression seals): replacements & retrofits

    On every detail (Wabo and various DOTs) the joint seal is always shown sitting on top of a neat little step: either a 1/2" strip of metal when the groove is armored or it is placed in the neat sawcut groove. I wonder if it might be alright to omit the little step that is shown (i.e. place the...

    Change in steel properties

    Say that a channel is welded to the bottom flange (of a simply supported wide-flange beam): That is, two welds (perpendicular to the beam) across the bottom flange, mid-span where the beam experiences its maximum stress. Due to the welding and welds (say fillet welds 1/3 the thickness of the...

    Roadway profile vert & horiz

    I'm looking at a set of plans (standard cast-in-place 4-span 2-lane slab with a metal rail) where the bridge is on a horizontal curve and vertical curve (sag) and I have some questions: 1) What is the cost, it must be more difficult to form? 2) Are there special issues structural, drainage...
