The Skill Being Assessed
In physical and infrastructure asset management, every major investment decision carries long-term consequences. Choosing between two competing projects requires more than just comparing their initial price tags. A professional analysis involves forecasting all costs over an asset's entire lifespan—from acquisition and operation to maintenance and eventual disposal. This is known as Life Cycle Costing (LCC).
This assessment challenges you to apply both LCC and Cost-Benefit Analysis (CBA). You will evaluate two distinct proposals for a critical piece of public infrastructure. Your analysis will form the basis of a formal recommendation, demonstrating your ability to make fiscally responsible and strategically sound decisions that public-sector and private-sector stakeholders rely on.
Your Task
You are a Junior Asset Analyst for the City of Northwood's Public Works Department. The city must replace the aging Northwood Creek Bridge, a critical transportation artery. Two proposals have been submitted for consideration. Your director has tasked you with analyzing both options to determine the most fiscally responsible choice over the long term.
Your task is to prepare a formal recommendation memo for the Director of Public Works. Your recommendation must be supported by a quantitative analysis.
Deliverables: 1. Analysis Spreadsheet: An Excel or Google Sheets file showing your Life Cycle Costing (LCC) and Cost-Benefit Analysis (CBA) for both bridge proposals. Clearly show your calculations for the Net Present Value of costs and the final Benefit-Cost Ratio for each option. 2. Recommendation Memo: A one-page memo addressed to the Director. It should briefly state your methodology, present the key findings from your analysis, and provide a clear, data-driven recommendation on which proposal the city should accept.
Resources and Data
To complete your analysis, you will use the following documents. The first is a formal request from your director, and the second provides the necessary financial data for your calculations.
Key Document: MEMORANDUM: Analysis of Northwood Creek Bridge Proposals
Northwood Creek Bridge Proposal Comparison
| Data Point | Proposal A: Steel Truss Bridge | Proposal B: Concrete Box Girder Bridge | Notes |
|---|---|---|---|
| Initial Construction Cost | $45,000,000 | $60,000,000 | Total upfront cost including design, materials, and labor. Proposal A benefits from modular, pre-fabricated components. |
| Asset Lifespan | 50 Years | 75 Years | The projected operational life of the bridge before requiring a complete replacement. |
| Annual Routine Maintenance | $500,000 | $150,000 | Covers inspections, painting, de-icing, and minor repairs. Steel trusses require more frequent painting and joint inspections. |
| Major Rehabilitation Cost (at Year 25) | $12,000,000 | $0 | A planned, one-time cost for deck replacement and structural coating for Proposal A. Not required for Proposal B within its lifespan. |
| Annual User Benefits (Economic) | $2,500,000 | $2,800,000 | Monetized value of reduced traffic congestion, fewer accidents, and lower vehicle operating costs. Higher for B due to wider lanes. |
| End-of-Life Salvage Value | $1,000,000 | $2,500,000 | Estimated net value from recycling materials at the end of the bridge's life. Higher for concrete due to material volume. |
| Construction Duration | 24 Months | 30 Months | Estimated time from groundbreaking to opening. Concrete requires longer curing times on-site. |
| Discount Rate (for NPV Analysis) | 5.0% | 5.0% | The standard rate used to evaluate the present value of future costs and benefits for both proposals. |
