Traditionally, the best option for contractors who don't have a large reserve of cash is renting or leasing. The contractor who rents construction equipment only has to calculate the rent he or she is going pay. The contractor is not saddled with equipment, which incurs a loss when left unused. In the construction industry, a general rule of thumb is that if you don't utilize a piece of equipment at least 60 to 70 percent of the time, you should consider renting. Assume you are completing a 20,000 sq. ft. construction project of a brick exterior, three stories in height, with standard interior construction; metal stud walls, steel joists, concrete flooring over metal deck. Provide at least two examples of construction equipment that you would rent and explain why. Next, consider your two examples. Under what conditions might you consider purchasing said equipment?
