    Adfreeze / frost heave on caissons supporting solar canopy structure

    The geotech report specifically gave the numbers from the values from the Canadian Foundation Engineering Manual and called out the depth as 42". So I'm ok with how to determine that number. Basically, 30" diameter caissons, multiply the 1300 psf by the circumference by the 42" depth. That...

    Adfreeze / frost heave on caissons supporting solar canopy structure

    I'm using AllPile to analyze it. You're saying that for the first 42" to set the phi angle to zero, that way the caisson isn't relying on that layer for uplift resistance too? Thanks.

    Adfreeze / frost heave on caissons supporting solar canopy structure

    I have a project in Connecticut for the foundation design on a solar parking lot canopy. I have soils values from a geotech report. I also have reactions from the steel manufacturer. The soils report calls for adfreeze behavior to a depth of 42" and gives values from the Canadian Foundation...

    Dam engineering design / mass concrete design

    Thanks msquared48, Will the forming manual deal with the question of the number of required lifts before the shoring can be removed? In other words, I need to analyze the headwall as a largely non-reinforced mass concrete beam. I would imagine that after the beam is thick enough, it would act...

    Dam engineering design / mass concrete design

    I previously posted this under the Structural forum and it appears to have been removed. If you had responded to that thread, please respond here as well since I very much need an answer to this question. I have been asked to determine the number of 5' lifts that will be required on a...

    Directional Boring under canal/railroad

    To everyone who's already replied to this: thank you very much. You've all given me a lot of useful leads.

    Directional Boring under canal/railroad

    Actually, the boring is for an electrical run. The wires will be in a 4" PVC conduit.

    Directional Boring under canal/railroad

    I have a client asking me to stamp a drawing for a directional bore underneath a railroad and a 50' wide x 10' deep canal which is not concrete lined. The boring company will be pulling a 10" dia. steel casing through and then a 4" pvc conduit inside of it. The bore would be 10' below the...
