Abstract: 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.

Abstract: A quay wall absorption block includes a back wall, a cap, and a half columnar wall extending between the back wall and cap. The half columnar wall defines a plurality of chamber surfaces and mating surfaces on opposite sides thereof such that the chamber surfaces define portions of a plurality of closed-end flow chambers on opposite sides of the half columnar wall when the mating surfaces are in contact with corresponding mating surfaces of other quay wall absorption blocks. The half columnar wall also defines a plurality of flow paths that extends therethrough to fluidly connect the plurality of closed-end flow chambers on opposite sides of the half columnar wall.

Abstract: An architectural design system receives input specifying plans for (i) a site having a surface area, (ii) post-development buildings, parking lots or sidewalks arranged to occupy a portion of the surface area greater than existing buildings, parking lots and sidewalks on the site, and (iii) post-development rain water management apparatus arranged to occupy a portion of the surface area and configured to at least slow the rate at which rain water drains from the site. The system further computes a water score for the site based on expected rainfall for the site and the perviousness of the site under pre-settlement, existing and post-development conditions, and outputs the water score.
