Cost-Effective
By avoiding expensive replacement, preservation techniques save owners millions by identifying, addressing, and preventing corrosion problems.
- Emergency repairs are much more expensive than proactive preservation.
- For the cost of replacing one bridge, owners can preserve five.
- Indirect costs of replacement, such as traffic closings/delays and resulting lost productivity, are estimated to be 10 times that of direct corrosion costs.
Environmentally Beneficial
By providing alternatives to large-scale replacement projects, in-depth evaluation and preservation techniques are instrumental in reducing carbon dioxide and other harmful emissions.
- 2.35 billion tons of cement are produced per year – 1 cubic meter of concrete per person.
- Cement production accounts for 5-10% of the world's total carbon dioxide emissions.
- A 10% carbon dioxide reduction in cement processes would accomplish one-fifth of the Kyoto Protocol’s Carbon Dioxide reduction goal – 5.2%
Crucial to Enabling Service Life Goals
By providing owners with vital information and quality services, in-depth evaluation equips owners to meet service life extension goals.
- Only repair what is necessary
- Accurately measure remaining life and time-to-failure
- Create comprehensive plans to save significant long-term costs and realize full service life
