Step 1: Schedule Equipment Delivery

Begin your project by scheduling the delivery of your equipment. Ensure the telehandlers, skidsteer, man lift or genie lift, and mini hoe are ready on site when you start your work.

Step 3: Schedule Screw Pile Installer

Step 4: Determine the Starting Location

Identify the easiest posts to start with. Starting with the easier posts allows you to develop an efficient system, expediting the overall process.

Step 5: Measure the Roof Beam Height

Set up a rotary laser to accurately measure the current height of the roof beam. If the beam is sagging, try to measure this in an area where it isn't sagging, or determine the height you want to set the new posts to.

Step 6: Secure the Beam

Use a telehandler to hold up the beam while you remove one or two posts.

Step 13: Install the New Post

Tilt up the new post and lift it into the saddle. It may be helpful to fabricate a special post lifting tool for this step.

Step 14: Fasten the Post

Fasten the new post to the saddle and the beam using GRK structural screws or through bolts.
