Abstract
A buried pipeline construction laser alignment survey platform mountable on manhole sections. The platform has a platform deck and two opposing sets of foldable handrail mounted on the perimeter of the platform deck which are inter-connected by safety chains to complete a safety perimeter. A manhole access in the platform deck has a slideable access cover providing for a closed set-up position, an open access position, and a partially open laser alignment position. One or more sets of anchor pedestals on the bottom of the platform deck provide for securing the platform to manhole sections of one or more diameters.
