MARS 8.5 Facility Cost For ecast System

A Unique Planning Tool

To compete for limited resources, capital asset managers must have a clear and defensible view of funding and staffing needs.

MARS creates a link between your facility assets and a unique library of engineering tasks and service costs to provide detailed budget requirements.

Estimate Deferred Maintenance without Costly Inspections

MARS is used by many government agencies and other large facility owners to estimate deferred maintenance costs based on life cycle principles. In a large scale (3 million square feet) test, MARS estimates were within 10 percent of those from a traditional inspection—for less than half the cost. MARS estimates meet FASAB Standard Number 6, DOE 430.1B, and Executive Order 13327 reporting requirements.

Focus on M&R Investment

Forecast your facility maintenance & repair (M&R) requirements for up to 50 years and then drill down to component level detail, year by year. Also monitor the changing value of your assets as MARS automatically calculates your current facility condition index (FCI) and net value of your capital asset portfolio. Use the included Plant Replacement Value Calculator to refine the FCI calculation.

Forecast Operations Costs

The MARS operations cost module forecasts ten facility operations costs, including: energy, water & sewer, custodial, refuse, grounds, road clearance, pest control, security, telecommunications, and management. Estimates are driven by exclusive Whitestone data for 148 asset types and 234 U.S. and Canadian metropolitan areas.

Each cost is carefully defined for consistency with commercial and government charts of accounts.

Notes

Maintenance and repair (M&R) is the collection of activities necessary for keeping a building in good working order. Other tasks associated with building operation such as custodial services, landscaping, waste disposal, and the provision of central utilities are not included in our definition of M&R.

For the purposes of this book, M&R activities are divided into three types:

1. Preventative maintenance (PM) and minor repair consists of scheduled tasks that sustain a component's level of service during a prescribed lifetime.

2. Unscheduled maintenance consists of service calls,

emergency response, and other tasks that cannot be individually anticipated.

3. Renewal and replacement consists of component overhaul or major replacement tasks. These tasks extend a component lifetime, and reset the schedule of PM and minor repair tasks.

Size is expressed in gross square feet (GSFT), and includes the entire area within the assets perimeter.

All costs throughout the book are expressed in mid-year 2009 dollars.

Costs for Canadian areas are reported in Canadian dollars, unless noted otherwise.

Acknowledgments

Each year, completing this book depends on information, advice, and support from a wide variety of sources. Much of the employment, wage, and price data were provided by federal agencies, and these are credited specifically throughout the book. Many of the models were defined with the generous assistance of a panel of engineers from Jacobs Facilities, Inc. To understand new technologies and discover new data sources, we continue to rely on the patience and expertise of a wide variety of construction trade organizations and professional associations; to validate costs, we had innumerable conversations with manufacturers, wholesalers, and tradesmen. To all these individuals and

organizations, we express our gratitude.

Our knowledge of facilities finance issues has grown greatly with the project support provided by various U.S. federal agencies. The Office of the Deputy Under Secretary of Defense for Installations and

Environment supported basic research addressing the estimation of facility recapitalization costs—due to obsolescence, changes in use, asset safety & code, etc.—not included in this book, but a related topic of importance for capital asset management.1 This office also underwrote much of the research leading to the operations cost forecasting capability of MARS. 2 While originally focused on Defense activities, this capability has been expanded to general commercial practice in later versions of MARS and described in the Whitestone Facility Operations Cost Reference.

We continue to be surprised at the ways in which the data from this book can be used. In 2004, a study for Johnson Controls used Whitestone asset cost profiles to estimate the market for facility M&R (over

$210 billion) in North America. The following year, a study to validate the condition of nuclear weapons sites for the National Nuclear Security Administration, U.S. Department of Energy, used Whitestone data and the MARS Facility Cost Forecast System to confirm deferred maintenance requirements and forecast future M&R costs. This data is currently being updated as part of a comprehensive model to evaluate the full life-cycle costs for alternative approaches to weapons production and storage.

In 2006, Jacobs Facilities used MARS in an extensive study of life-cycle costs of facility security components for the U.S. Internal Revenue Service. That same year, a study done in partnership with Lawrence Livermore National Laboratory used MARS to demonstrate the M&R cost savings of extending mechanical equipment service life beyond published guidelines.3 Also in 2006, a project for the Battelle Energy Alliance validated over 14,000 detailed M&R tasks and subtasks. All of these efforts have added to our component library and increased our understanding of complex facilities.

Last year, Whitestone launched Brickbits.com, an online life-cycle cost calculator for homeowners. Based on residential housing models developed in MARS, the Brickbits site provides benchmarks for twelve residential costs—from home cleaning to taxes—for zip codes in the U.S. Early in 2008, Whitestone provided life-cycle cost profiles for BIMStorm LAX, a 24-hour rapid design exercise for 420 assets in downtown Los Angeles.4

An ongoing project for the Agricultural Research Service, U.S. Department of Agriculture, demonstrates the utility of Whitestone models for complying with Executive Order 13327—Federal Real Property Asset Management.5 This Order requires improved real property data and asset management plans from major property holding U.S. federal agencies.6

Finally, a recent study of energy retrofits, supported by Pacific Northwest National Laboratory (PNNL), increased our knowledge of the life-cycle costs of a broad collection of energy saving options.7

1. Getting Started

How to Use This Book:

Start at the beginning and work towards the back.

This book is organized around cost profiles for the models shown in Chapter 2. The subsequent chapters present the detailed data—labor rates, material costs, and component life-cycle tasks—that go into these estimates. We suggest you work your way through the book according to your required level of detail.

Everything costs more in New York.

The model cost forecasts shown in Chapter 2 are made for the Washington, D.C. area. Before these forecasts are used for other areas, they should be modified to reflect local labor costs and life-cycles. The local maintenance cost index, shown in Chapter 3.1, is based on a comparison of costs across 234 areas for the same model—the 2 Story Office Building—using Washington, D.C. as a reference point.

A facility is just a collection of assets.

Model costs can be used to approximate the M&R budget for an entire facility. Categorize your facility inventory according to the 72 Whitestone models in Chapter 2, and then multiply the actual total square footage in each category by the appropriate model's estimated cost (expressed in costs per square feet).

Be sure to adjust the costs for your area using the local maintenance cost index.

Don’t hesitate to mix and match.

The model cost forecasts can be used as a point of departure for making more specific estimates. All of the information necessary is provided: adjust for a different area using the local maintenance cost index in Chapter 3.1; substitute different components with the data provided in Chapter 5; or put the entire

forecast in a different base year using the appropriate index from Chapter 4.

Use the right inflation rate.

The costs of roof repairs and HVAC maintenance have not grown at the same rate as milk and eggs, yet many contractors, facility managers, and even cost analysts still use a consumer price index when estimating M&R cost inflation. National-level cost indexes for three types of M&R construction— non- residential, residential, and military—are computed in Chapter 4.

Remember, it’s warmer in Phoenix.

M&R requirements for HVAC equipment vary substantially across areas. More specifically, an air conditioner in Alaska is likely to experience much less demand, and have lower M&R costs, than one in Arizona. This explains the extensive listing of repair frequencies by climate zones shown in Chapter 5.2.

(18)

Frequently Asked Questions:

What is the lifetime M&R funding requirement for an individual asset?

A model 2 Story Office Building in the Washington, D.C. area will cost an annual average of $3.12 per GSFT or 1.59 percent of replacement cost over a 50-year service life. Average costs for other asset types varied from $87.27 to $0.96 per GSFT. Detailed cost profiles for 72 model assets are shown in Chapter 2.

How can M&R costs be estimated for an actual asset?

The model shown in Chapter 2 can be used as a point of departure for making more specific estimates.

All of the necessary information is provided: adjust for a different area using the local maintenance cost index in Chapter 3.1; substitute different components with the data provided in Chapter 5; or put the entire forecast in a different base year using the appropriate index from Chapter 4.1.

How do M&R costs vary across areas?

An index of local maintenance costs shows New York, NY has the highest average M&R cost in our 234- area sample, at $3.93 per GSFT for a model 2 Story Office Building; San Juan, PR has the lowest rate at

$2.13 for the same asset. For a cost comparison among areas, see Chapter 3.1.

How will regional M&R costs change in 2009?

Labor costs account for over 40 percent of M&R costs. Recent wage agreements indicate that the highest wage increases in 2009, averaging 5.1 percent, will be in the Southwest Pacific. Construction wage changes are summarized by region in Chapter 6.

What will 2009 rates for construction trades be in specific areas?

The Chicago area has the highest average contract labor rates of the 234 areas studied. A contract electrician in Chicago will cost an estimated $80.57 per hour, while a contract plumber will cost an estimated $82.23. A listing of contract labor costs by trade for each area is shown in Chapter 3.3.

What is the inflation rate for commercial M&R costs?

In 2009, M&R costs for commercial and public assets will decrease at an estimated annual rate of 3.6 percent, military facilities costs will decrease by 5.9 percent, and residential assets costs will decrease by 8.2 percent. By comparison, new construction costs will decrease by 3.9 percent and consumer prices by 0.9 percent during the same period. Whitestone M&R construction indexes are shown in Chapter 4.

How are M&R tasks distributed between contract workers and in-house staff?

For estimation purposes, we assume in-house staff members at shop rates shown in Chapter 3.2 perform preventative maintenance, minor repairs, and unscheduled maintenance. We assume major repair and replacement tasks are done by contract workers at rates shown in Chapter 3.3.

What are the labor requirements for M&R?

Labor requirements, like costs, vary by asset type, size, and location. A model 2 Story Office Building in the Washington, D.C. area requires an annual average of 5,394 hours over a 50-year service life. Labor requirements for other asset types are shown in Table A-2 in the Appendix.

How sensitive are Whitestone estimates?

There is no straightforward answer, as estimates of M&R costs for entire assets necessarily vary by location, components, and use. Also important are unscheduled maintenance multipliers, in-house markup rates, and types of utilization. Different values for these factors can change M&R costs substantially, as shown in the discussion of estimate sensitivity in Chapter 6.

Where does Whitestone data come from?

Data sources, key assumptions, and a complete explanation of the MARS forecast model are presented in Chapter 6.
