It is common to think of a building as a "thermal battery" that absorbs heat during the day (for example by the mass of a concrete structure) and releases it at night when temperatures .

Geotechnical failures usually occur due to a combination of factors such as construction design, geological conditions, construction problems and natural disasters. The presence of groundwater raises problems with respect to labor Geological Considerations In If deeper excavations for the project are required, then the boring should be carried to at least 1.5 times the depth of the excavation to locate and determine groundwater levels in any aquifers that may exist; if any are found, a dewatering system can be designed prior to construction.
