building economist Interview Questions and Answers

1. What is a building economist?

   • Answer: A building economist is a professional who applies economic principles and quantitative analysis to the planning, design, construction, and operation of buildings and infrastructure projects. They assess the cost-effectiveness and financial viability of projects, optimize resource allocation, and advise on investment decisions.

2. Explain the difference between cost estimation and cost control.

   • Answer: Cost estimation is the process of predicting the likely cost of a project before it begins. Cost control involves monitoring and managing actual costs during construction to ensure they stay within the estimated budget. Cost control uses techniques like earned value management and change order management.

3. What are some common cost estimation methods?

   • Answer: Common methods include comparative analysis (using similar past projects), parametric estimation (using statistical relationships between project characteristics and cost), detailed quantity takeoff, and bottom-up estimation (estimating the cost of individual components).

4. How do you handle uncertainty and risk in cost estimation?

   • Answer: By using probabilistic methods (Monte Carlo simulations), sensitivity analysis, contingency planning, and including a contingency buffer in the estimate to account for unforeseen events and cost overruns.

5. What are some key factors influencing building costs?

   • Answer: Material prices, labor costs, location, project complexity, design features, regulations, inflation, and market conditions.

6. Describe your experience with life-cycle cost analysis (LCCA).

   • Answer: [Candidate should describe their experience with LCCA, including software used, methodologies applied, and the types of projects analyzed. Example: "I have extensive experience conducting LCCAs using software like [Software Name]. I've worked on projects ranging from [Project Type] to [Project Type], analyzing the initial cost, operation & maintenance costs, and end-of-life costs to determine the most cost-effective option over the building's lifetime."]

7. What is the role of value engineering in a building project?

   • Answer: Value engineering is a systematic process to improve the value of a project by identifying and eliminating unnecessary costs without sacrificing performance or quality. It involves a collaborative effort of the project team.

8. How do you incorporate sustainability considerations into cost estimations?

   • Answer: By considering the initial costs of sustainable materials and technologies, as well as the long-term savings in energy and maintenance costs. This includes factoring in potential incentives and rebates for sustainable building practices.

9. Explain the concept of present value and its importance in building economics.
