Abstract
A method for installing ceiling panels in a tunnel comprises installing a plurality of brackets in the tunnel roof and disposing a horizontal platform at an intermediate height in the tunnel. A plurality of ceiling panels are lifted onto the platform where the panels are then linked together to form a ceiling section. The platform is then raised upwardly until the panels are adjacent the brackets, and the panels are then secured to the brackets.
