Accelerated Bridge, Boston, Massachusetts
Geocomp is providing Active Risk Management™ (ARM) and sequencing services as part of an 8-year
$2.98 billion federally-funded program to rehabilitate and restore a portfolio of Boston-area bridges.
The ARM contract is helping to identify, analyze, and evaluate risks and determine their potential
impacts on project costs and schedules and to use the results to develop an optimal sequencing of the project elements.
Money saved as part of the Active Risk Management™ project was actively reinvested into the long term program and allowed
for additional bridges to be included in the program and rehabilitated. This helped reduce the total number of structurally
deficient bridges in the State of Massachusetts.
iLevee, New Orleans, Louisiana
Geocomp used risk assessment tools and decision theory aids to identify where monitoring can
be deployed to provide the largest reduction in risk. Within this context, Geocomp developed a
probability analysis tool which integrates and transforms data from field instruments and routine field
inspections into quantitative measures of risk for each levee component to help prioritize investment decisions.
I-91 Viaduct Structural Life Extension, Springfield, Massachusetts
The precise instrumentation installation and data processing using rainflow-counting algorithms
developed by Geocomp allowed CME to perform fatigue life calculations to determine the remaining
service life of the superstructure using field data to validate their model. Results of this work showed
that the structure could be used for another 35 years with only deck replacement. This reduced costs
from $800 to $200 million.
The Colony, Park City, Utah
Geocomp was retained to determine the extent and impact of corrosion of steel reinforcements in
side hill roadways, vehicle bridges and ski cross-overs on a 4,400 acre mountain slope ski-in and
out residential community. Intrusion of deicing salts led to accelerated corrosion of the metallic
reinforcements. A detailed protocol to determine remaining service life for over 50 structures was
established using reliability analysis. A phased program for remediation was developed to assist the client in developing
present value remediation costs. This approach saved the client millions of dollars over the alternative of removing and
replacing all structures.
