Tower inspections are an important source of revenue for many firms in the tower industry, and they are a very important tool for tower owners and users in protecting their investment.
Since there is such fierce competition for tower inspecting jobs, inspectors must be efficient to ensure short-term profit; at the same time the tower inspector's reputation is on the line in every job, so the results must be correct to ensure the firm's future.
Of course, tower owners and users expect quality results and consistent reporting, even from the lowest bidder.
