Elevator Retro Fit
The school required an elevator be installed for their students.
Top and Last Plate
The top plate is the last plate going into the ground.
Footing and Base Prep
Once the floor was removed some of the soils were removed for the space needed for the ending of the elevator assembly. In each corner a helical pier would be installed to support the footing and concrete base.
1st Helical
Helical piers are torqued into place deep into the earth. A gear head rotates the pier so power needed to turn the pier is measured as torque. The disk plates act to draw the pier down into the ground and for support of the concrete footing and base that will be poured later.
Last plate Entering the Ground
As the gear head turns the helical pier, this is the top and last plate entering the soil.
Pier to Pier Contact
Our helical piers are engineered to have pier to pier contact at each junction section. The 2 pin hole and zinc coated bolts are only necessary for the installation. Once the helical pier is installed the load of the structure is vertical held because of the shaft to shaft connection of each pier installed.
2nd Story Floor Cut Out
The 2nd story floor is cut out to make the space needed to operate an elevator.
Flat Pier Cap
Once the helical pier is driven into place a flat cap is attached to the top of the pier that will be poured with concrete to be a part of the footing and concrete base for the elevator.
