11.8.2. Life Cycle Costing

Try these first

1. 1.

   What does LCC stand for?

   Hint

   Think of the total expenses involved over time.

2. 2.

   Why is durable concrete important in LCC?

   Hint

   Consider how often repairs are needed for lasting structures.

3. 3.

   What does LCC focus on?

   • Initial Costs Only
   • Total Costs Over Life
   • Short-term Costs

   Hint

   Think about expenses incurred from start to finish.

4. 4.

   True or False: Higher initial costs of durable materials always lead to higher life cycle costs.

   • True
   • False

   Hint

   Consider the long-term perspective.

5. 5.

   Consider a city planning a new bridge. They can either use standard or high-performance concrete. Calculate how much more they expect to pay upfront and the possible savings over ten years in maintenance.

   Hint

   Consider rates of maintenance costs for both options.

6. 6.

   Analyze the sustainability impact of using reclaimed concrete aggregates in new mixes versus traditional aggregates. How would this affect the lifecycle perspective?

   Hint

   Think about how long each type lasts and what happens at the end of most concrete’s lifecycle.
