Question 1

What does life cycle costing primarily focus on?

  • Initial construction costs
  • Total costs over the lifespan
  • Energy efficiency only

💡 Hint: Think about the entire lifespan, not just the beginning.

Question 2

True or False: Concrete typically requires more maintenance than timber.

  • True
  • False

💡 Hint: Consider material properties and their long-term performance.

Challenge Problems

Push your limits with challenges.

Question 1

Consider a project where a concrete structure has a projected lifespan of 50 years, incurring $1,000 for initial costs and $200 for maintenance every 10 years. Compare it with a timber structure costing $700 initially and $300 in maintenance every 10 years for the same period, and identify which offers a better life cycle cost.

💡 Hint: Calculate total costs over 50 years for both structures.

Question 2

You are tasked with determining the optimal material for a new hospital considering not only the initial construction costs but the energy savings from lower operational demands over a 30-year time frame. Given specific costs and expected energy savings for concrete and steel, which would be the ideal choice?

💡 Hint: Factor in the energy efficiency provided by thermal mass in concrete.
