Sandia's Building Restoration Operations Optimization Model (BROOM) software system was developed to help decision makers - during the planning phase and throughout actual cleanup operations - to speed up reoccupation and return to service of contaminated buildings and facilities.

The tool provides an efficient and scientifically defensible approach to planning and executing sampling and cleanup activities. To date, there has been no comprehensive system for handling and assisting with this process.

Sandia is a National Nuclear Security Administration laboratory.

Many potential users, applications

Originally developed for use during cleanup of facilities following a bioterrorism attack, BROOM is easily adapted to other spatial domains where accurate and efficient data tracking, management, optimization, and analysis of samples are needed. Possible users and/or applications of BROOM include:

Environmental cleanup (including Superfund sites)
Remediation companies
Industrial hygiene
Forensics/crime units
Incident characterization
Decontamination contractors
Health agencies
Airports, subways
Government buildings
Ports of entry
Water utilities
Gas and electric utilities
Chemical plants
Other critical infrastructure facilities
Cost, efficiency savings could reach into multi-millions of dollars

The cost to shut down public facilities, plants, or businesses can be enormous. According to Business Week, costs of the 23-day closure of Ronald Reagan National Airport in Washington, DC after the 9/11 attacks have been estimated at $330 million per day to the airport and Northern Virginia businesses, and $27 million to state and local tax revenues.

Costs to clean up the Hart Senate office building after an anthrax-laced letter was discovered were originally estimated at $5 million, but ballooned to $28 million. The Hart cleanup took three months and involved collecting and processing more than 10,000 air and surface samples.

Moreover, lost revenue estimates for an anthrax attack at a busy airport approach nearly $30 billion. Increasing efficiency in cleanup operations by using electronic data collection, sample management, and streamlined analysis processes could significantly impact the bottom line for cleanup efforts and related economic factors.

BROOM's integrated data collection, fast and efficient data management, and easy-to-use visualization software provides the ability to manage information needed to help assess contamination within a facility, most effectively and efficiently plan operations to remediate that contamination, complete the clean up, and restore the facility to operation.

BROOM improves the efficiency of cleanup operations, minimizes facility downtime, and provides a transparent basis for reopening. The last factor is critical in gaining public and regulatory acceptance for declaring a facility to be "clean" and safe to reoccupy.

Sophisticated yet easy-to-use hardware

"Collecting samples from a contaminated facility is currently a painstaking, time-consuming process for HazMat responders," says Jane Ann Lamph, a Sandia engineer and business development associate leading the BROOM commercialization effort. BROOM makes the procedure far more efficient and accurate, she said, with the aid of a handheld device, easy-to-use software, scanner, and wireless laser range finder that maps out with pinpoint accuracy where samples are taken.

The centerpiece of BROOM is a handheld device, which looks like a typical PDA but packs a large amount of data and information.

The device uses sophisticated algorithms to generate contamination maps and layouts of the location where the responders are collecting samples and to develop statistically based sampling plans; a barcode scanner to track tagged samples and maintain chain-of-custody records; and electronic forms to capture information such as the sample type, surface type and texture, collection method, and other important data that is collectively managed by the BROOM software.

During time-sensitive events when sampling data is needed quickly, information can be wirelessly transmitted to a PC or central command station outside the contaminated area in a secure manner. The results can be displayed on a map on both the handheld device and the PC, allowing decision makers to determine if an area is truly clean, and to reopen facilities as quickly as possible.

The BROOM system is the result of a three-year development effort funded by the Department of Homeland Security. The research included demonstrations and exercises with San Francisco International Airport and other model facilities.

Sandia is a multiprogram laboratory operated by Sandia Corporation, a Lockheed Martin company, for the U.S. Department of Energy's National Nuclear Security Administration. With main facilities in Albuquerque, N.M., and Livermore, Calif., Sandia has major R&D responsibilities in national security, energy and environmental technologies, and economic competitiveness.
