This process for the above listed project involved the screwing of specifically
designed and engineered posts applicable for this project. PSI readings were
taken on each individual post during the installation and with the use of a
correlation table these measurements are listed and described below:
• PSI/Torque: Pounds per square inch/The rotational pressure taken to
drive the post
• Depth: The distance downward from its top surface.
• Type: Piers are categorized for each individual specific project
• Bearing: Downward pressure post can withstand
• Pinned: Bored into solid immoveable rock reaching maximum compression
and tension.Once the post was driven one additional test was performed, the
percussion test.This test involves striking the post with a sledgehammer, 5
times per set,while being measured for resistance. Once there is zero
downward moment the post and pressures are verified.
• Uplift: The force required to pull the post out of the ground, the uplift value is
half of the bearing.

otes:
i.The maximum tensile load capacity can be obtained,conservatively,by halving the values of the bearing capacity in compression shown in the selection
table.
.The maximum compressive load(SLS)shown in the selection table limit the settlements to 12 mm(112 inch).
.The maximum compressive bearing capacity(SLS)is determined by the maximum torque allowable by the installation equipment used(see
specifications of installation equipment)
.When the pile is laterally unsupported(soil very loose/soft,liquefiable soils,water and air),the structural strength of the pile must be approved
by the technical department of Techno Metal Post.
.The values of lateral capacity are average values and can be modified,more or less,depending on the characteristics of the existing soil.
atoments:
For any questions,please contact the technical department of Techno Metal Post
Larger Techno Metal Post can be used for applications requiring a lateral or bending resistance higher than shown in the selection table.
