A method of constructing a structure in which an item is to be installed at an elevated height on the structure. Hoists are hung from the structure. A platform is moved from ground level and positioned at a first elevated position between ground level and the hoists. The platform is attached to the hoists at the first elevated position. After the platform has been attached to the hoists, the item is moved onto the platform. The item is lifted on the platform to a second elevated position for installation at the elevated height on the structure and the item is installed at the elevated height.

An improved bridge overhang bracket assembly may include top, diagonal and side members. A hanger element may be mounted to the top member and pivotally attached proximate to the top end of the side member. The hanger element may be translatable along the top member for adjusting its longitudinal position, to vary the positions of the diagonal and side members quickly and easily, without disassembly, and may enable folding of the members to a shipping/storage position. A second hanger element may be mounted to the top member for attaching the assembly to a tie rod. The diagonal member may include at least one connection tab for receiving a bolt to connect the top and diagonal members together in the shipping/storage position. Also disclosed is a fastener assembly for securing a side rail to a T-bolt channel.

A suspension system for supporting an operator from a parapet of a building has first and second support assemblies adapted to engage the parapet, a first support line extending from the first support assembly to the first operator, and a second support line extending from the second support assembly to the first operator. At least one of the first and second support assemblies engages the parapet to support the operator relative to building. To allow the operator to move relative to the building, the weight of the operator is supported by one of the first and second support assemblies while the other of the first and second support assemblies is moved.

A roofer support apparatus for providing a level support on a pitched roof includes a base mount with a plurality of adjustment apertures and a chain slot. A mount bottom side is positioned on a pitched roof. A support is pivotably coupled to the base mount and receives a board. A pivot bracket is coupled to the support and is selectively engageable with two of the plurality of adjustment apertures to fix the pivot bracket to the base mount with the support horizontal. A chain is coupled to the base mount and is selectively engageable with the chain slot of the mount front side. A chain anchor is coupled to the chain. The chain anchor is secured to an opposite roof side of the pitched roof.

A lightweight composite roofing support system is disclosed. The roofing support system includes a longitudinally-extending core member having a wedge-shaped lateral cross-section, a first side, and a second side, the first side and the second side tapering toward one another at a first predetermined acute angle (), the core member comprising a core material. The roofing support system also includes a cover layer comprising a cover material, the cover layer disposed on and covering at least one of the first side and the second side, the cover material being substantially more compressible than the core material, the core member and cover layer comprising a first roofing support.

A suspended scaffold rigging system includes a base to be attached with a roof of a building and an arm attached with the base. The arm includes an end portion to extend over and away from an edge of the roof when the base is attached with the roof and a cable guide defined by the end portion. The system further includes a scaffold and a suspension cable to be attached to the scaffold, to be guided by the cable guide, and to be attached to a tie-back of the building such that that tie-back bears a load of the scaffold and the arm spaces the suspension cable away from the edge of the roof.

An extendible lateral support arm having at least two elongate arm members coupled together and displaceable relative each other. The first arm defines a first end of the extendible arm. The second arm defines a second end of the extendible arm. The distance between the first end and the second end is variable. The first end presents a first head that can engage a building structure. The second end presents a second head that can be secured to an adjacent structure.
