A debris collection apparatus for a maritime vessel includes a shroud and a plurality of support structures. Each of the plurality support structures include a boot defining a cavity and configured to be secured to the vessel, a foot sized to fit within the cavity, a staff cap, a stabilizer base configured to be secured to the vessel, an elevational staff section connected to the foot and the staff cap terminal, and a horizontal staff section connected to the staff cap and the stabilizer base. The foot is inserted into the boot to secure the support structures in a rigid position, and the shroud is connected to both staff caps and the vessel. The stabilizer base can include a connection loop, and the shroud can be configured to be connected to the connection loop in order to connect the shroud to the vessel.

An access tunnel system comprising at least one access tunnel for the sheltered guidance of persons to a vehicle, an aircraft, a building or the like. In accordance with the invention, a node element is provided at which the access tunnel opens and which at least one further access tunnel adjoins.

A sidewalk architectural feature defining a length, a width and a height, wherein the length is greater than the width, the sidewalk architectural feature including a plurality of vertical members extending in a direction generally parallel with the height, the plurality of vertical members defining a plurality of bays of the sidewalk architectural feature including a first bay and a second bay disposed adjacent to the first bay; and a framework comprising a plurality of spanning members extending between adjacent vertical members, wherein at least a portion of the framework is coupled to at least one of the plurality of vertical members through a flexible interface.

A temporary shield erected between two flanged structural members of a bridge or other structure, and a method for erection of the shield. A plurality of length-adjustable beams have end portions which are rested on flanges respectively of the structural members in a manner so that they are not fixed thereto. Decking is attached to the beams. At least one elongate member is cantileverly extended from at least one of the beams to underlie a structural member flange to prevent wind lift-up of the shield. A shield is also erected by adjusting the lengths of and hanging the end portions of each of a multitude of beams from the structure with the beams lying side-by-side. Decking is attached to the beams.

A sidewalk shed for placement proximal to a building includes: a plurality of canopy support arrangements including base members securable to grade; a beam support structure securably disposed to upper portions of the plurality of the canopy support arrangements; and a canopy structure securably disposed to the beam support structure. The plurality of canopy support arrangements includes dual canopy support arrangements and single support arrangements. The canopy structure includes a parapet wall and a decking.

An adjustable scaffolding tunnel assembly. The assembly includes a first pair of posts connected on upper and lower portions thereof to a second pair of posts via grooved members. A first cross beam is positioned between the first pair of posts, and a second cross beam is positioned between the second pair of posts. A plurality of support beams is disposed between the first and second cross beams. The first and second pairs of posts are vertically adjustable, and the first and second cross beams and the support beams are laterally adjustable. In this manner, a height and a width of the assembly are individually adjustable. The adjustable scaffolding tunnel assembly can hold one or more isolation members, such as wood or drywall, to isolate an interior of the assembly from an exterior of the assembly.

Provided is a platform positioning system including a platform and an elevator, wherein a cabin of the elevator is movable along a wall segment of a building, wherein the platform positioning system further includes a first attachment mechanism for releasably attaching the platform to the cabin, wherein the motion of the cabin and the platform are coupled to each other when the platform is attached to the cabin, and a second attachment mechanism for releasably attaching the platform to the wall segment.

An adjustable scaffolding tunnel assembly. The assembly includes a first pair of posts connected on upper and lower portions thereof to a second pair of posts via grooved members. A first cross beam is positioned between the first pair of posts, and a second cross beam is positioned between the second pair of posts. A plurality of support beams is disposed between the first and second cross beams. The first and second pairs of posts are vertically adjustable, and the first and second cross beams and the support beams are laterally adjustable. In this manner, a height and a width of the assembly are individually adjustable. The adjustable scaffolding tunnel assembly can hold one or more isolation members, such as wood or drywall, to isolate an interior of the assembly from an exterior of the assembly.

A temporary shield erected between two flanged structural members of a bridge or other structure, a kit therefor, and a method for erection of the shield. A plurality of length-adjustable beams have end portions which are rested on flanges respectively of the structural members. Decking is attached to the beams. At least one elongate member is cantileverly extended from at least one of the beams to underlie a structural member flange to prevent wind lift up of the shield.

A system and method of a temporary protective structural system. The system includes a plurality of frame members. The frame members define a pair of opposing studs and integrated top plate. The system also includes noggings connecting the studs. Ceiling joists are also included. The combination creates at least one free-standing tunnel module. Vertical wall panels are secured to the exteriors of the free-standing tunnel modules, thereby vertically enclosing the free-standing tunnel modules. Horizontal ceiling panels are secured to an exterior ceiling area of the tunnel modules. Horizontal floor panels provide a protective surface for the floor. When constructed, the combination of elements and tunnel modules create a protective barrier for sensitive surfaces in a construction zone.
