Building Pathology: Survey of defects and cost estimate of a case study renovation project.

This is a methodology of ‘Building Pathology’ explained through theoretically and practically by applying it on a case study. The stages are developed from the references of the previous books knowledge, combined by following codes of Normal 1/88 and latest methods of rehabilitation and protection. The stages are followed with an order from Initial investigation of visual survey, continuing with diagnostic analysis based on the intrinsic causes due to the conditions of site and architectural errors, Extrinsic natural causes due to climatic, temperature, weather along with some anthropic condition caused by human actions. The results from the diagnostics are further classified according to class based on type of damage as structural and nonstructural. Another class based on nature of degradation mechanism as physical, chemical and biological. Final class based on Type of alteration as reversible and irreversible. The classified alterations are represented using the codes of Normal 1/88 which indicates the Hatching in AutoCAD with the exact dimensions of the case study taken. By using the AutoCAD file with exact dimensions and hatchings calculation of individual alterations is possible. By the Detailed analysis and esteemed calculations of alterations type of renovation can be suggested in an order as cleaning followed by repairs and strengthening finally protection measurements can be ensured. As from the suggested renovation and market price of material along with the present labor, technicians daily charge the final cost estimation can be calculated.
