Details about construction projects, building and occupancy permits, and other information can thus be stored and easily retrieved. Although inspections are primarily visual, inspectors often use tape measures, survey instruments, metering devices, and test equipment such as concrete strength measurers. They often keep a daily 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 something that does not comply with the appropriate codes, ordinances, contract specifications, or approved plans. If the deficiency is not corrected within a reasonable or specified period of time, government inspectors have authority to issue a stop-work order.
Many inspectors also investigate construction or alterations being done without proper permits.
Violators of permit laws are directed to obtain permits and submit to inspection. Construction inspectors ensure compliance with building codes, zoning regulations, and contract specifications. Working Conditions Construction and building inspectors usually work alone. However, several may be assigned to a large, complex project. They may spend much of their time in a field office reviewing blueprints, answering letters or telephone calls, writing reports, and scheduling inspections.
