LowTech Manufacturing’s Staged Construction
LowTech Manufacturing is building a new office complex next to its manufacturing plant. There are two plans. The first is a five-floor complex, where only three floors are needed for the first 3 to 10 years. The top two floors would remain empty until needed by LowTech. The second is a three-story building whose foundation and first three floors would accommodate adding another two floors later.
Building in two stages reduces the costs now, but total costs will increase substantially. Building in two stages allows flexibility in timing and in the exact design of the upper two floors. A probability distribution for when the space will be needed and data for the profitability estimates are summarized in the table below.
To simplify the calculations, your boss has said to assume that the benefits of having the new space are $1M per floor for each year the floor is needed. LowTech management has identified an interest rate of 10% and an analysis period of 20 years.
