PRESERVATION OF EVIDENCE   Preservation of Evidence - exact documentation and certification of the status quo, in particular of defects in existing objects. - facilitates claims for damages after renovation or extension of existing objects, or in the course of warranting, containment to the actual dimensions. During the period of construction process there is documentation of the „initial state“ of the object or objects adjacent to the building project before the start of work. After building activities are completed, the status quo is assessed once again. Thus, any actual damages accrued through building activities can be determined, a calculation of costs made, and appropriate renovation measures be proposed. In the course of warranting, damages due to the correction of defects are documented by a third party, in order to provide security against claims for damages. ACTIVITIES TO BE PERFORMED IN ADVANCE   - Providing existing plans and necessary documents. - Coordinating necessary target dates with the parties concerned. RECORDING OF THE INITIAL STATE   - Establishing a photographic documentation of any existing building defects. - Formulating a list of damages according to their location. - Formulating a description of the status quo. RECORDING THE STATUS QUO FOLLOWING BUILDING ACTIVITIES   - Establishing a further assessment of conditions after building activities are completed. - Formulating a report on any deviations from assessments of conditions before the start of work. - Assessing building deficiencies accrued from recent building activity, or assessing any deficiencies occurring within the warranty period. - Renovation concepts - Contingent cost analysis
