Stud gap marker tape 10 comprises a strip element 12; and a plurality of gap marks 14, to facilitate stud positioning, to thus facilitate wall building. Preferably a portion or a whole of an underside of the strip element is adhesive, to facilitate sticking the strip element to a plate. Preferably the stud gap marker tape is provided rolled up, as a roll of tape. Disclosure is also provided of an apparatus 501, to make gap marks on a plate, to facilitate stud positioning, to thus facilitate wall building.

A lumber use designation system includes a building construction plan that shows the layout, wall thickness, wall height, ceiling angles, etc., of a structure, which are color coded from a series of color codes each corresponding to a preselected, standard board size and length of lumber that should be selected for constructing a particular portion of the structure. The system includes a supply of lumber boards marked with a color code correlating to the color code found on the construction plans. The lumber boards may be imprinted by an ink spray head. A method of installing lumber during the construction of a structure is disclosed.

A horizontal portion of a frame, as a door header, of a predetermined length for installation between two adjacent studs of a stud wall spaced from one another. An installation tool, releasably mounted on a respective stud via a magnetic attachment, supports a respective end of the horizontal portion adjacent the metallic stud during attachment of the horizontal portion to the stud. A kit formed of at least one horizontal portion and at least one installation tool is also provided.

A centralized core and node system for use in an integrated component-based construction projects includes a centralized core configured to be positioned on at least one external wall of a building project. The centralized core includes a core frame to support one or more resource distribution mechanisms and a core shell connected to the frame to at least partially enclose the one or more resource distribution mechanisms and form at least one part of the external wall of the building project. The centralized core and node system also includes at least one resource node. The at least one resource node includes a node frame and at least one resource connection point. The resource connection point including a node input for connection to the centralized core and a node output for distributing a resource to a desired location in the building project.

A construction component for use in integrated component-based construction that includes a base member having a predetermined size and a marking fixed to an exterior surface of the base member. The marking including an identifier and at least one indicator, wherein the identifier identifies the base member's location in a centralized building model and the at least one indicator indicates a location of a second construction component relative to the base member.

A method of integrated component-based construction includes receiving construction project input data comprising characteristics of a construction project and preparing a centralized construction model based on the construction project input data and on a component library. The component library includes a plurality of construction components having a plurality of predetermined characteristics. The methods also includes determining a construction plan based on the centralized construction model comprising a plurality of factors and sending fabrication instruction data and factor data based on the centralized construction model. The fabrication instruction data includes fabrication instructions for the construction components in the centralized construction model, and the factor data includes grouping instructions for the grouping of the construction components into each factor of the plurality of factors. The method also includes sending assembly data based on the centralized construction model comprising instructions for completing each factor in the plurality of factors.

A truss stacking system has a main conveyor for conveying trusses of a plurality of diverse designs out of a production facility and into a stack building yard or warehouse. The main conveyor is attended by a dedicated truss stacking station for each of the diverse designs, and which station includes a truss lift sub-station and a stack-forming sub-station. Each truss lift sub-station has at least a pair of traveling masts that each raises and lowers at least one bunk (eg., fork). The bunks are raised to lift a selected truss off the outflow conveyor, the masts are driven on an outbound journey to support the lifted bunk in the airspace above the stack-forming station, and then the bunks are lowered to rest the truss on the stack. Stop posts assist in stripping the truss off the bunks.

Disclosed herein are embodiments of a floor panel seating assembly. The floor panel seating assembly can include adjustable, removable brackets or guides for guiding cross-members and joists of floor panels into their desired positions on a support structure. Also disclosed herein are embodiments of a method of seating a floor panel. The method can include providing one or more adjustable, removable bracket or guide, adjusting the guide(s) to accommodate the width of a wall of the support structure and/or the sizes of the cross-members or joists of the floor panel, mounting the guide(s) to the support structure, and lowering a floor panel into position on the support structure using the guide(s).

Modular crane attachment device for purlins is a crane attachment jig that attaches to the hook of a crane and functions to lift a plurality of purlins in one lift to place each purlin at the precise location on the rafters of a building under construction to allow for immediate attachment of all purlins to the rafters wherein each purlin is fastened into place while held by the crane and modular crane attachment device for purlins, which functions as a giant assembly jig in this manner. Modular crane attachment device for purlins is modular so that it can be broken down by hand into a bundle of 10-20 foot long structural members, fittings, and cables. Modular crane attachment device for purlins is modular so it can be assembled in any length and width to fit any application of any number and any length of purlins required for the building.
