The Troup Howell Bridge Replacement Project (Partnership), located in Rochester, NY, began in the
spring of 2004 and was completed in July 2007. The project involved replacing an existing bridge
with a new tiered-arch bridge over water while maintaining existing heavy traffic flow. There were
three main stages of the project:
- Stage 1 consisted of building new foundations under the existing bridge, constructing traffic
crossovers, and building a new entrance ramp.
- Stage 2 consisted of removing the existing south bridge and rebuilding a new south side of the
- Stage 3 consisted of removing the existing north bridge and rebuilding a new north side of the
Over the entire duration of the project, there were only two lost time work injuries, and over the
last year and a half of the project there were none. The project took 186,455 man hours to complete
and 104,216 hours were completed with no loss time injuries. This is significant due to much of the
work being conducted over water in extreme weather conditions.
Injury and Illness Rates Decline - Days Away,
Restricted and Transfer (DART)
Over the three years of the Partnership, the DART rate steadily decreased, with the average for Year
1 being 5.0. The DART rate was almost cut in half during the second year, and was 0.0 in the final
year. The average for the three years was 2.1 compared to the BLS industry national average of 3.5.

Also during the project, worker compensation costs were 16 cents less per hour
than the national industry average.
Safety and Health Culture Enhanced
The general contractor for the site, Edward Kraemer & Sons, Inc., implemented two safety programs
during the project. The first program was the behavioral safety program "BOSS" (Behavioral
Observation Safety System). Under BOSS, supervisory employees made continual behavioral-based
observations and conducted an intervention for any at risk behaviors noted.
The second program was the "TEAM" (Total Efficiency Attainment Meeting) program. Each foreman
conducted a daily TEAM meeting with his crew where work activities, material and equipment needed,
hazards and methods of mitigating them for the work were discussed. Dialogue during these meetings
with the crew included methods, production rates/goals, safety, and any inspection items or
incidents from the previous day.
The Partnership was formed to eliminate hazards and reduce injuries resulting
from the four focused construction hazards (falls, struck-by, caught-in\between, and electrocutions).
Specifically, the Partnership wanted to have a Days Away, Restricted and Transfer (DART) rate that was
less than the Bureau of Labor Statistics (BLS) data available for the most recent year. Other
objectives included having a strong emphasis on training for both supervisors and non-supervisory
employees, promoting safety and health programs, and encouraging a positive change within the local
