A permanent frost protected shallow foundation footing for a building is assembled from a plurality of form parts arranged in a chain that is partially below ground level to form a foundation perimeter. The form parts are made of a lightweight material such as insulating foam material shaped as an elongated sectional unit with an overhang part overhanging a cavity part of an interior cavity. The interior cavity has an opening for receiving a concrete pour concurrent with a concrete pour of a floor. Open ends of the assembled sectional units abut each other in end-to-end alignment to form an elongated cavity inside the perimeter chain of form parts that is filled with concrete. The overhang part may have a foot shape that fits inside the interior cavity of another form part that may also have a foot shape for compact storage or transport prior to assembly.

A support stand for supporting a volumetric modular unit above the ground is disclosed. The support stand includes a top portion with a top surface for contacting and supporting an underside of the modular unit above the ground. A bottom portion with a bottom surface supports the top portion at an elevation above the ground against the underside of the modular unit. An elevating portion has a top side connected to the top portion, a bottom side connected to the bottom portion, and an elevating span between the top side and the bottom side. A pad is connected to the bottom portion. The pad has a bottom surface for contacting and supporting the bottom portion against the ground, an inner pad perimeter and an outer pad perimeter. The top surface is parallel with the bottom surface. The underside and weight of the modular unit is supported on the top surface.

An anchor bolt diagnosing system includes a vibration sensing clip that clips an anchor bolt, and senses a vibration power of the anchor bolt, a blow sensing hammer that gives a blow to the anchor bolt clipped by the vibration sensing clip, and senses blow strength, and a diagnoser that obtains the vibration power and the blow strength output from the vibration sensing clip and the blow sensing hammer, and diagnoses soundness of the anchor bolt in accordance with whether a ratio of the vibration power to the blow strength is higher than a predetermined value.

A method for constructing a building structure using gravity and weight of the building structure is provided. The method includes designing an architecture and a construction plan of the building structure, planning an initial box for a structural design, tuning a ground required for construction of the building structure, constructing the initial box as per the planning, constructing an upper floor on the initial box, constructing remaining parts of the building structure including foundation for the building structure, and assembling a plurality of temporary structures to the building structure.

The disclosure relates to compositions that include sand mixed with a stabilizing agent that includes i) hydrocarbon derivative fibers and cement, ii) acrylic-based polymer emulsions, or iii) hydrocarbon derivative fibers and acrylic-based polymer emulsions, as well as related methods.

A foundation system utilizes conventional construction barriers, such as Jersey barriers, or the like, to form a foundation stem wall. Various modifications are made to the construction barriers to permit their use in both on frame and off frame construction. The foundation system of the present invention may also be used for conventional construction, including stud wall construction and block home construction. Generally, an on frame construction technique is used for modular or metal structures where the metal frame remains on the bottom of the walls. This permits, for example, the re-addition of a tongue, axles, wheels, and the like, to allow the building to be moved if desired. With off frame construction, the modular sections of the building are lifted off the frame and attached to, for example, a stem wall via connectors, straps, or the like.
