The inspection of exterior doors falls under two different sections of the ComSOP: 6.5.2 Exterior and 6.5.11 Doors, Windows, and Interiors. When inspecting exterior doors, an inspector should look at: the main entry doors, service doors, sliding glass doors, and overhead and loading dock doors. It is important to know each of the different types…
Fenestration refers to the arrangement of windows and doors on the exterior of a building, including any glass panel, window, door, curtain wall, or skylight unit. Fenestration can include any building materials that are used to create an opening between the exterior and interior, but glass is the most commonly used material because of its…

Concrete slab foundations, commonly called slabs, are the most common foundation system found in commercial buildings. Concrete is a mixture of Portland cement, sand, gravel, and water. When concrete is allowed to cure or harden, it can support the load of a building. There are two basic types of slabs found in commercial properties: monolithic…
In the construction industry, a schedule is a tabular approach to organizing and presenting lists of building materials, systems, and components. For instance, schedules are common for windows in a set of design blueprints. The schedule provides a graphical representation or list of all windows required for a construction job and indicates the number of…
There are very few constants in construction or inspections, but one basic construction principle is that buildings should be plumb, level, square and straight (PLSS). In inspecting a structure, anything that deviates from this would be considered an issue or defect. Many inspectors are not structural engineers or architects, and a commercial property inspector is…
There are various types of parking areas at commercial properties, ranging from multi-story parking structures to gravel parking pads. Multi-story parking garages can be complex and contain systems beyond most inspectors’ comfort level. In this case, the inspector can exclude the parking structure altogether through the pre-inspection agreement or by bringing a specialty consultant to…

Commercial buildings should only be supplied by one electrical service. This generally prohibits the installation of more than one set of service conductors in a building. An…
Terms You Should Know Alternating current (AC): A current that periodically reverses direction and magnitude continuously. Direct current (DC): A current that does not reverse direction but maintains the same single steady flow. Single-phase: A circuit energized by a single alternating current. Three-phase/3-phase: A wiring system consisting of four wires and used in industrial and…
Transformers are used to change AC voltage levels. These can be termed as step-up or step-down, depending upon the need to increase or decrease in the voltage level. This is necessary in commercial buildings because the main service voltage is static, and certain distribution systems may require something different. A good example might be the…
