For example, inspectors may use laptop computers to record their findings while inspecting a site. Most inspectors use computers to help them monitor the status of construction inspection activities and keep track of issued permits. Although inspections are primarily visual, most inspectors, except home inspectors, may use tape measures, survey instruments, metering devices, and test equipment such as concrete strength measurers. They keep a log of their work, take photographs, file reports, and, if necessary, act on their findings. For example, construction inspectors notify the construction contractor, superintendent, or supervisor when they discover a code or ordinance violation or something that does not comply with the contract specifications or approved plans.
Many inspectors also investigate construction or alterations being done without proper permits.
Inspectors who are employees of municipalities enforce laws pertaining to the proper design, construction, and use of buildings. They direct violators of permit laws to obtain permits and submit to inspection. However, several may be assigned to large, complex projects, particularly because inspectors tend to specialize in different areas of construction. Though they spend considerable time inspecting construction work sites, inspectors also spend time in a field office reviewing blueprints, answering letters or telephone calls, writing reports, and scheduling inspections. Inspection sites are dirty and may be cluttered with tools, materials, or debris.
