This system is a pilot risk-based model using a generic methodology to allow building owners and consultants to select the most appropriate repair technique for a corroded damaged reinforced concrete structure. 

The recommendation of the most appropriate techniques are based on two main parameters: 
Time To Corrosion Initiation and the End of Service Life, which can be obtained from the project details.  

The model contains tools which can be used for calculating the cost of the selected repair techniques.  The selected repair techniques are then compared using a whole life costing analysis tool incorporated within the model.
  • The Model
    • provides guidance on the most appropriate repair strategy
    • predicts the residual life of the structure and the time to failure of the repair
    • identifies the most cost effective way to meet the client's service life requirements bearing in mind the nature of the structure
The model should not be used for drawing up budgets for repair without consulting an experienced contractor for his\her estimate after looking at the job

The diagram below presents an overall concept on the basic steps in using the model.  The model is made up of web pages, which is activated by the various links on the diagram.  A brief description of the various links on the diagram is presented in the box below

The flexibility of the system means that any one of the four main steps can be used, if the appropriate inputs are already known.

This is not a structural tool therefore structural analysis should be carried out if there are concern about overloading or loss of capacity.
