Impermeable and secondary handling systems, ground support systems, excavation 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 . Two geological problems that affect roads after their construction are: (a) Frost action and (b) Erosion of slopes along roads. The result is that the primary cal personnel must be available to handle emergencies.
