An extraplanetary habitat system includes a habitat located on a site including a layer of regolith material and one or more heat-generating systems located in the habitat. A heat exchanger is operably connected to the habitat. The heat exchanger is located beneath the layer of regolith material and is configured to conduct the heat from the habitat into the layer of regolith material. A method of cooling one or more heat generating components of an extraplanetary habitat includes directing a flow of fluid from the habitat to a heat exchanger located beneath a layer of regolith material, exchanging thermal energy between the flow of fluid and the regolith material, thereby cooling the volume of fluid, and directing the flow of fluid from the heat exchanger to the habitat, thus cooling the habitat.

A data centre comprises a plurality of sections assembled together to define a unitary structure such that there exists at least one personnel area that spans at least two sections; wherein the sections comprise a first section with which there is associated a first service-carrying chassis and a second section with which there is associated a second service-carrying chassis, each of the first and second service-carrying chassis comprising a frame onto which is mounted components of at least two different services; the first and second chassis are connected to each other by means of a junction between the first and second chassis; and the first and second sections each include a ceiling and the first service carrying chassis is mounted on the ceiling of the first section and the second service carrying chassis is mounted on the ceiling of the second section.

Provided herewith is a system for assembling a temporary structure using a plurality of separate members. A first member has ends at opposite sides of an elongated body portion, with notches on the top and bottom sides of each end. A second member has ends with notches formed on opposite between the ends. These notches enable the first and second members to engage with other such separate members. A third member has a triangular shape that functions as a roof truss with opposing sloped surfaces and an underside. A pair of truss notches is formed at positions corresponding to the notches of the first member, for each engaging with one of the plurality of separate members. The third member also includes feature hooks, formed on the sloped surfaces, for engaging with a fourth member defined by a planar roofing material having a plurality of holes.

A method of construction of composite wall module system in which a first wall module and a second wall module are coupled to the first wall module by a vertical joint. The vertical joint is comprised of plurality of anchors and reinforcement bars as well as steel side plates allowing composite wall steel faceplates to be discontinuous across the vertical joint. The faceplates of the first and second modules are not made continuous across the vertical joint through continuous welding. The vertical wall joint further includes fill disposed between faceplates and side plates adjacent to anchors and reinforcement bars.

A mast assembly for a drilling rig includes a mast formed from a plurality of mast subunits. The mast assembly includes a lower drilling machine, upper drilling machine, and upper mud assembly, each of which is coupled to and movable vertically relative to the mast. The mast subunits are separable when the mast is in a transport configuration such that the LDM is positioned in a first subunit and the UDM is in a second subunit of the mast when the mast is in the transport configuration. The mast assembly may be used during a continuous drilling operation.

Transportable and rapidly deployable air supported structure systems and related methods are disclosed. The air supported structure systems include at least one transportable container. The systems also include a flexible outer membrane configured to couple to a base in a substantially air-tight manner. The systems further include at least one air handling mechanism contained within the at least one container configured to force air between the outer membrane and the base to form an enclosure therebetween via internal air pressure. The systems are configurable between a packaged state with the outer membrane contained within the at least one container, and a deployed state with the outer membrane being coupled to the base and the at least one air handling mechanism forming the enclosure via the internal air pressure. The at least one container may form a portion of the base and/or provide for ingress and egress with the enclosure.

A building truss including a structural floor element, a vertical support on each side of the structural floor element, rafters spanning the vertical supports, a structural horizontal tie which interconnects the rafters, and a roof peak on the horizontal tie. A building is constructed by erecting multiple trusses parallel to each other in sequence in a longitudinal direction spanning one gable end to the opposed gable end. Each building truss defines the full room and roof spaces and provides the required structural strength. Each truss defines a 2D envelope; the floor element spanning in the horizontal direction, vertical supports for the vertical direction, and a roof assembly joining the two vertical supports. Each truss is unitary and constructing the multiple trusses parallel to each other provides a 3D structural building envelope.

Embodiments are directed to a hinged perimeter barrier or wall for an industrial worksite. The perimeter barrier may be formed from a series of wall sections that include hinged panels. The wall sections may be delivered to the worksite in an unextended configuration and then hoisted (by crane) into an extended configuration. A top panel may include a set of lifting features that may be engaged to raise (unfold) the panels and form the wall section. The wall section may be secured to a structural support using a support attachment assembly. The perimeter barrier may be used to mitigate various byproducts of an industrial worksite, including noise, dust, odor, light, and so on. The panels may be formed from an acoustic dampening material, visual mitigation material, and/or various other materials as may be appropriate for a given worksite.

A head pad assembly includes a plurality of head pad subassemblies pivotably joined along their lateral edge so as to allow vertical rotation of one subassembly relative to an adjoining subassembly when the head pad is actuated. At least one head pad subassembly includes a stiff upper backing portion and a lower compressible pad. The head pad assembly further includes one or more flexible hinges coupling the plurality of head pad subassemblies along their lateral edges to effect the vertical rotation. The head pad assembly further includes an actuator assembly configured to raise and lower the plurality of head pad subassemblies between an upper position and a lower, sealing position.

To provide a roof structure free from generation of a dead space, capable of reducing a load moment. A roof structure including a roof (1) supported by a post (2) is a cantilever structure having the front end of the roof (1) formed in a free end and the rear end connected to the upper end of the post (2). The lower end of the post (2) is fixed in a concrete foundation (5). The post (2) is tilted with the upper end directed backward and with the lower end directed forward. A counter moment cm generated on the post (2) at the time of application of a load to the roof (1) reduces a load moment (M) generated by the load, thereby bringing the post (2) into an advantageous state in strength. The configuration of the post (2) with two post members and a vertical connecting member (10) connecting the post members facilitates the construction of the post (2) to be tilted at a desired angle.
