About the project

Challenge, approach and results.

The project, PZI – Reconstruction of Part of LC Hmezad – Kričej – Reš – G1 – 'TRC REŠ', began implementation in 2008, for which he was responsible himself, from ** preparation** ** of the tender, all ** necessary documentation, to ** execution** ** of the project. And this proved to be the case, as ** they had to ** continuously pump out water with pumps. Shortly after the start of works, the Municipality of Radlje ob Dravi commissioned us to ** construct an auxiliary structure for pedestrians, so that crossing the stream would be without danger.

Solution and Method

The project, PZI – Reconstruction of Part of LC Hmezad – Kričej – Reš – G1 – 'TRC REŠ', began implementation in 2008, for which he was responsible himself, from ** preparation** ** of the tender, all ** necessary documentation, to ** execution** ** of the project. In the first section of the diploma thesis, he ** presented the project and commented on it. All copies from the project – ** calculations, project sketches** … – are precisely listed.

It is evident that the project was carefully planned, with all necessary preliminary investigations. The only shortcoming was that ** he did not have a hydraulic assessment of the bridge prepared** for 100-year waters from the water management authority, namely the company Drava vodnogospodarsko podjetje Ptuj, d. d. ** This was obtained** later. The report also influenced the execution of the bridge, as the requirement for the clear height of the bridge was 0.5 m higher than designed.

He did not detect other problems in connection with the project and they did not arise, or they remained hidden. It is clear that in construction we cannot foresee everything, as a very large number of factors can be decisive, e.g. weather, over which we have no influence. We can only prepare effectively for weather inconveniences.

As a local, he knew the location of the bridge well and was aware of the responsibility, as he was undertaking such a project – bridge construction – for the first time. Therefore, he took the task seriously and made decisions thoughtfully, so that the author would not have to 'pay' for mistakes later. The problem was also the River Drava in the immediate vicinity and very shallow groundwater at this location.

Results

And this proved to be the case, as they had to ** continuously pump out water with pumps. Shortly after the start of works, the Municipality of Radlje ob Dravi commissioned us to ** construct an auxiliary structure for pedestrians, so that crossing the stream would be without danger. Thus they made a safe auxiliary footbridge.

All other problems that arose during construction are described in detail in the diploma thesis. Already during the preparation of the tender, with the help of the project, he was able to accurately calculate all costs that they would have in the project, and also anticipate the work procedure. From the project it was clear that ** the most difficult would be the execution of the foundations**, as they were designed at a very great depth, approximately 1.5 m below the level of the stream that the bridge crosses. During the construction of the bridge, much could have been improved and costs thereby reduced, but we learn from mistakes, and in the next such project he will certainly be more attentive and try to execute the project even better.

I believe that in the diploma thesis he clearly showed how to read a project and how to construct a bridge. The project ** was very successful**, as even after seven years there are no visible deformations on the structure.
