    Manager Says Keep the Restraints — I Think They’re Unnecessary. Who’s Right?

    What K values are you using? I don't have section properties for metric shapes, but eyeballing this- your KL/r may be approaching 200 based on a Fixed-free condition

    Index for 12 page calculations?

    As Aesur stated, nearly everything out west requires calcs. When you include computer printouts, 12 pages sounds about right. As tempting as it is to be sarcastic to the reviewer, it's a lot easier (and will take less of your time) to just add the index and be done with it.

    1099 Fee Split Dispute

    If this were an employee/employer relationship- the owner should be getting two to three times what the engineer does. This covers overhead, liability, employer taxes... Being a 1099 does narrow that gap. Since he is sealing the plans, the owner does still front the liability (insurance is not a...

    Punching shear on S.O.G.

    Be careful with the Shentu Method. It allows for very large loads on a slab on grade City of Los Angeles recognized this method many years ago but has since retracted allowing it. I have not been able to find any documentation stating why they reversed themselves. Anyone know anything more?

    Car lift post foundation

    Seismic is a very real concern. The footing for these lifts can get thick in high seismic locations due to the bolt requirements Obviously, you can't predict when an earthquake will hit- so there is a significant risk that the car can be in the elevated position when it occurs. The lift vendors...

    Remote SE Work

    If the experienced and mature engineers are remote- who is training the young engineers? Are experienced engineers more efficient when remote? In many cases- yes they are. The new engineers are paying the price for this though. They are not picking up on the knowledge that those remote...

    Contractor will not provide rebar shop drawings?

    JAE, I was just typing the same thing. Everyone else- please be careful about the word Certify. It is a word that is casually mentioned- but has significant implications. As engineers, we should not be certifying construction

    Insulated Panels

    If they are doing work in California, the manufacturers likely have this testing. Kolpak does.

    Non-competes

    Just a note: Non-Competes and Non-Solisitation agreements are two different things. Non-competes generally restrict someone from getting another job in the same field- this is what the government has concerns with. Non-solicitations indicate that you won't pursue company clients for a period of...

    Structural vs Civil Engineering Pay

    Be careful how often you do that DTS491. After a few of these- potential employers start to wonder why you can't hold a job. If I see a resume with 5 jobs in the last 10 years- it's going in the trash.

    Resistance of 12ga brace wire

    I agree- In high seismic areas, 12 ga splay wire does not pencil out. Look at 8 ga. It's a little more common than 9 ga. In reality- the code required 4 psf DL for a lay in ceiling is very conservative. I suspect that some municipalities that provide "approved standards" may take this into...

    Wind Load on Guardrail w/ Glass Panel

    Is the 200 lb. point load (or 50 plf) ASD or ULT? Most everything else in the code is being set up as ULT loads now- but this number has not changed in many code cycles. I suspect it is intended to be an ASD load.

    216-49 Wire Mesh

    In case anyone is interested, the wire institute responded: The 216 refers to spacing in inches of the longitudinal and transverse wires, respectively, while the 49 refers to wire gauge of the longitudinal and transverse wires, respectively. In this case, the style represents 4 gauge wires...

    216-49 Wire Mesh
