Abstract: A collapsible barrier has at least three integrally-formed wall sections with a plurality of contiguous living hinges, as a series, joining each adjacent pair of wall sections, the at least three wall sections including two endmost wall sections joinable to form an upright structure. A collapsible barrier may include a plurality of interconnected wall sections each having a top-facing side, where one of the top-facing sides has a pocket adapted for securely holding a light. A thermoformed unitary plastic object may include at least two wall sections, at least one hinge member connecting adjacent interior ones of the wall sections' longitudinal sides, the hinge member comprising a plurality of interconnected living hinges, where a nominal thickness of the at least one hinge members of the thermoformed unitary plastic object approximates 0.100 inch.

Abstract: A template for temporary placement on the open upper end of a below-ground structure, including a rectangular body matching key dimensions of a permanent ground-level member to be installed, the body having an open bottom to engage the open upper end of the below-ground structure, a raised top surface, a back road-edge portion on one side of the body, and upright sidewalls. A method for using the template to facilitate adjustment of positioning of below-ground structures on which permanent ground-level members will be installed, the method involving placing, removing and re-placing the template while determining and adjusting positioning of the below-ground structure.
