### Phase III  
In the incorporation of the information into the 3D model regarding inspections and other conservation data, it is necessary, after cataloguing the damage, to generate a database that allows importing accurately. The database starts from a worksheet file that contains different fields (Table 2) adapted to each family group. This will facilitate its programming in Dynamo and will include the following information:  
1. Damage codification, to identify in the 3D model, using the following structure: three initials in reference to the group of family: perimeter clamping ring (PR), structural arches (ES and AP), cover (VN and AP) and pillars (PL), category and damage. For example, \"VN_DUR_EFL\" to the efflorescence found in the cover by durability;
2. Category;
3. Damage;
4. Level of damage: The value 0 is assigned when the element does not include any damage; 1 to light damage; 2 to grave and 3 to major damage;
5. Severity: light (L), grave (G) and major damage (MG);
6. Associate repairs according to the values of damage and severity;
7. Observations: comments and suggestions it may consider relevant;
8. Picture of damage;
9. Measurements: with the partner unit of damage (unit, volume, length or area);
10. Repair cost. \begin{table}
\begin{tabular}{c c c} \hline \hline
**ID** & **VN_DUR_EFL** & **VN_DUR_COR** & **VN_DUR_FIS** \\ \hline CATEGORY & Durability of materials & Durability of materials & Durability of materials \\ \hline DAMAGE & Efflorescence or stain & Corrosion & Fissures and cracks \\ \hline LEVEL OF DAMAGE & 3 & 0 & 1 \\ \hline SEVERITY & MG & – & L \\ \hline OBSERVATIONS & – & – & – \\ \hline \multirow{2}{*}{ASOCIATE REPAIRS} & Treatment designed to remove efflorescence & Not necessary & Injection of acrylic or epoxy resins \\ \hline PICTURE & – & – & – \\ \hline MEASUREMENTS & 0.00 & 0.00 & 0.00 \\ \hline COST & EUR 76.73 & 0.00 & 148.42 \\ \hline UNITS & EUR/m\({}^{2}\) & EUR/m\({}^{2}\) & EUR/m\({}^{2}\) \\ \hline \hline \end{tabular}

Table 2: Worksheet example of one element for data transfer into the 3D model. \begin{table}
\begin{tabular}{c c c} \hline \hline
**DAMAGE** & **PHATOLOGY** \\ \hline Reinforcement uncovered & Loss of reinforcement concrete topcoat \\ \hline Gravel clumps & Bad concrete installation \\ \hline Corrosion & Corrosion of the rebars in concrete by sulphate or saline attack \\ \hline Material degradation & End of life \\ \hline Concrete detachment & Concrete carbonation, oxidation of the reinforcements or hit \\ \hline Efflorescence or stain & Deterioration by biological attacks or presence of humidity \\ \hline Fissures and cracks & Concrete carbonation or oxidation of the reinforcements \\ \hline Fissures and cracks & Due to the rheological factors in concrete \\ \hline Graffities & Vandalism \\ \hline Corrosion points & Insolated corrosion points in concrete \\ \hline \hline \end{tabular}

Table 1: Examples of damages in the perimeter clamping ring to the catalogue. A technical data and inspection report sheet can be generated that summarises all the data entered to the 3D model for each element (Figure 6), including a global measure of the damage. For proper external data transfer, it was required to create the parameters in the 3D model associated to the four groups of families. Thus, the coded information of the worksheet was entered in the 3D model by Dynamo and can be consulted in the properties of the element within the 3D model. As can be seen in Figure 7, three classes of common discipline project parameters are distinguished in Revit: text (severity and rate of damage, observations and repairs), numbers (measurement and cost) and images. Figure 6: (**a**) Technical data sheet with the inspection report to each element; (**b**) An example application. These parameters can also be associated with established color patterns to display the element and its damage as a resemblance of the traffic light colors (Figure 8).
