Abstract: The disclosure describes, in part, apparatuses and methods for installing structures (e.g., foundations, footings, anchors, abutments, etc.) at work sites, such as difficult-access work sites. In some instances, a rotating drill assembly is assembled over a target location in order to excavate a radial array of batter-angled shafts associated with the target location in preparation for the installation of a radial array of micropiles. An operator utilizes the rotating drill in combination with a foundation pile schedule/decision matrix to design and install the radial array of batter-angled micropiles. This disclosure also describes techniques for designing, fabricating and installing structural caps to be coupled to the installed radial array batter angled micropiles. These structural caps are lightweight and, thus, more portable to difficult-access sites where they are coupled to the micropiles forming a foundation for structure to be installed at the difficult-access site.

Abstract: The disclosure describes, in part, techniques for designing, fabricating and installing structural caps with a core and composite sleeves to be coupled to structural members of a foundation, such as an installed radial array of batter angled micropiles. These structural caps with sleeves are lightweight and, thus, more portable to difficult-access sites. Once at the sites, operators may fixedly couple these caps to the micropiles or other structural members to form a foundation for a structure to be installed at the difficult-access site.
