Abstract: A construction transportation system comprises at least one transport assembly having gross dimensions generally corresponding to those of a standard freight container. The transport assembly comprises at least two construction components. Each of the two construction components has a first gross dimension whose maximum value is generally equal to C.sub.1 /x, where C.sub.1 is the width of a standard freight container, and x is greater than or equal to 1. Each of the two components has a second gross dimension perpendicular to the first dimension whose maximum value is generally equal to C.sub.2 /y, where C.sub.2 is the length of a standard freight container, and y is greater than 1. Each of the two components has a third gross dimension perpendicular to the first and second dimensions. At least a first side of each of the two components extends in the directions of that components' first and third dimensions, and that first side is provided with connectors.

Abstract: A construction transportation assembly comprising a buoyant general construction component having eight corner portions defining a rectangular parallelpiped locus with a length and a width generally corresponding to those of an ISO standard freight container, and two specialty components mounted on top of the general component laterally adjacent each other and lying within the length and width of the locus.

Abstract: A method and apparatus for forming elevated structures. A first construction component is emplaced at a construction site, supported by an underlying earth formation. A second construction component is locked in cantilevered relation to the first such component. A support is extended downwardly from the second component, distal the first component, into load bearing engagement with the earth formation, whereafter the second component is interlocked to the support. The ends of the longitudinal components have improved locks in which a connector of the male lock can be passed through a receiving bore in a female lock only if oriented in a particular angular position, whereafter, if rotated to a different angular position, it cannot be withdrawn from the receiving bore. Similar locks are provided for interconnecting such longitudinal components in side-by-side relation via transom components.
