A contractor is proposing telescoping their temporary casings for our drilled pier. Several of the drilled piers are in uplift, more so than the weight of the concrete.Everything I have found about telescoping the casings has this line: "This procedure is most often used for drilled shafts that...
I'm looking to put in a footing or pier for an equipment support. Loads are very small (about 2k axial, 3 k*ft moment). I've got some old boring logs and the area I'd like to put the footer is in miscellaneous fill. I was hoping to use a 5'x5' (or smaller) footing or 3' pier setting at about 5'...
An outside engineer firm is proposing a 10' diameter by 49' drilled shaft in soft clay soil. Using the geotechnical report, the axial load resistance is 266 kips. The pole supported has an axial load of 58 kips, but the foundation alone weighs 577 kips. This raised some flags for our engineering...

A legacy practice of my engineering group has been to cut a hole in our base plate and embed an 8x8x1/4 HSS column 5/8" into the plate. The new manager wants detailed calculations on each structure, including base plate design. It is my understanding that the individual that detailed our base...
As seen in the example attachments, several engineers in the utility industry (where members experience significant moment/torsional loading) believe the use of stiffeners assists the overall structural design. It is believed, on the other hand by myself and few others that stiffeners do little...
