Three methods for the preparation of maintenance budgets are discussed--(1) a traditional method, inconclusive and obsolete, based on gross square footage, (2) the formula approach method based on building classification (wood-frame, masonry-wood, masonry-concrete) with maintenance cost factors for each type plus custodial service rates by type of area services (square footage serviced, salary, materials), and (3) the system of standards for work loading method based on minimum, median, and ideal standards for each custodial job.
