Unless authorized by the MCES Finance Director, MCES staff and consultants should use the following assumptions and methodologies in all financial analysis and budget development.
| Labor (including benefits): | 3.5% |
| Electricity: | 5.5% (2008 - 2012), 4% after |
| Other expenses: | 3.0% |
| Construction (for capital expenses in future years): | 4.0% or contract provisions, if available |
| Discount Rate to use in analysis* | 5.0% |
*This is the average annual cost of capital (net interest cost of bonds) for the past ten years. |
|
| Buildings/Structures | 40 years |
| Gravity Sewers | 80 years |
| Forcemains (dual-pipes, corrosion-resistant materials) | 40 years |
| Process Piping | 30 years |
| Equipment | Varies, 20 years is typical |
| Mechanical & Electrical Systems | 20 years |
| Instrumentation & Control | 15 years |
| Mobile Equipment | 10 years |
| Computer Hardware and Software | 4 years |
| Factor to use before adjusting for inflation* | |
| Non-mobile equipment | 1.25 |
| Mobile equipment | 1.00 |
*This accounts for higher replacement cost due to newer technology, installation, and purchasing equipment separately from the original construction project. Use these factors unless there is compelling reason to use different rates. |
|
| Master Plans | 50 years |
| Facility Plans | 20 years |
| Interceptors | 50 years |
| Treatment Plants | 20 years |
| Other Capital Projects | Life of the project's main/major structure |
| Projects that depend on a specific contract | Contract Term |
| For assets that are not fully depreciated at the end of the analysis horizon | Maximum Terminal Value = cost less straight line depreciation to terminal date. |
| Minimum Terminal Value = scrap value of materials less demolition costs. | |
| For land (if applicable) | Original land purchase price ( a conservative estimate) |
For decision-making, such as alternatives analysis, use incremental cost analysis methodology. For pricing services, use a full cost approach, and consult MCES Finance for additional guidance.
| As a percent of construction cost | |
| Master/Area Planning - Undeveloped Design Details & contingencies | 50% |
| Facility Planning - Undeveloped Design Details & contingencies | 30% |
| Engineering, Administrative, and Legal costs | 20% * |
|
* This is not to be compounded with the above factors (apply the 20% to Capital Costs before the above factors are applied) |
|
| Electricity (Treatment Plant avg) | $.0625/kwh |
| Electricity (all other) | $.0675/kwh |
| Natural Gas - Firm (includes distribution charge) | $10.50/MMBtu |
| Natural Gas - Interruptible (includes distribution charge) | $7.75/MMBtu |
| Diesel Fuel | $3.10/gallon |
| Polymer | Depends on sludge and process |
| Chlorine (1-ton cylinder) | $510 |
| Sulfur Dioxide (1-ton cylinder) | $500 |
| Caustic Soda | $1.45/gallon |
| Sodium Hypochlorite | $.70/gallon |
|

$80,000
(1,800 hours work time per year) |
|
Labor Salaries & Benefits - Maintenance (excludes overtime) |
$80,000
(1,800 hours work time per year) |
| Indirect Carbon Costs (Xcel Energy): | |||
| Electricity: | $.0054 per KWH | ||
| Direct (on-site) Carbon Costs: | |||
| From Energy Sources: | |||
| Natural gas: | $.054 per therm | ||
| Distillate fuel oil: | $.073 per therm | ||
| Propane (LPG): | $.060 per therm | ||

| From Exhaust (these costs include global warming multipliers): | |||
| Methane: | $207 per ton | ||
| Nitrous Oxide: | $2,790 per ton | ||
*These costs are in addition to the regular cost of these items. Detailed Analysis in Word doc |
