Structural Framework – Tilt-up Panels

Topic: Structural Framework – Tilt-up Panels Issued by: V.P., WorkSafe Services
Statute: General Regulation 91-191 Date Issued: August 15, 2006
Section: 94.2(1) Date Revised:

Question:
What are the requirements for the erection of tilt-up panels?

Answer:
While there is sometimes confusion, precast concrete panels are generally panels that are manufactured off site in a controlled factory setting and then transported on site. Tilt-up panels are generally manufactured on site. For the purposes of these regulations, the distinction is not important once the panels are on site. If the panel is part of the structural framework, section 94.2 applies.
