The aim of this investigation is the following findings: structure technical usefulness and conditions of safe ser- vice, list of potential detriments, which should be made in a near future or in urgent procedure, the necessity of general investigation of structure or principal inspection of particular elements. The routine inspection should be conducted by road maintenance service.
The general aim of this investigation is the assessment structure condition and listing of any structure changes occurred during its service. There are the following find- ings obtained after the investigation: the structure techni- cal usefulness and conditions of safe service, list of po- tential detriments, which should be made in a near future or in urgent procedure, the necessity of principal investi- gation of structure or special inspection of particular ele- ments. The general inspection should be conducted by graduated in Civil Engineering person, who has been trained at special bridge courses.

The general aims of the investigation are the following findings: the structure technical usefulness and safe ser- vice conditions, list of potential deteriorations, which should be made in a near future or in urgent procedure, the necessity of special inspection. The principal inspec- tion should be conducted by the team of specialist leaded by graduated in Civil Engineering person, who has been trained at special bridge courses.
This inspection is set up when the previous ones show its necessity or a minor accident has happened (severe im- pact, flood, fire etc.). The main aim of the special inspec- tion is to asses whether the structure or its part assure the safe service and to point out potential repairing or strengthening method. The inspection is carried out by qualified specialist (usually universities or research institu- tions) using sophisticated tools (calculations, investiga- tions, experiments, test loading etc.)

Table 17. Inspection types in Poland (One inspection may recommend a new inspection of a higher level).
The condition assessment of the whole structure is composed from the partial as- sessment of every part of the structure, organized in 12 main groups. Each of them receives an evaluation rated in a six grading scale shown in Table 18 and the current bridge technical condition is calculated as the average of each element assessment.
