Comparison of superstructure execution according to PZI documentation and cold process

In the diploma thesis, I describe a comparison or analysis of two different methods. In the continuation of the writing, four hypotheses will be defined and compared with the results of the analyses. In the first hypothesis, the two methods described above will be compared according to the schedule.

Solution and method

In the diploma thesis, I describe a comparison or analysis of two different methods. These are two different reconstruction methods, one of which was implemented over the past two years on the project 'Reconstruction of regional road R2-436, section 1328 Počehova – Zg. Kungota, from km 0+050 to km 5+742' and one of which will be described through the research of the diploma thesis.

Results

In the continuation of the writing, four hypotheses will be defined and compared with the results of the analyses. In the first hypothesis, the two methods described above will be compared according to the schedule. An analysis will be made of which method takes longer or less time.

The analyses will be carried out on the basis of prepared schedules, which will be prepared in MS Project, and the results will be described on this basis. It is anticipated that the PZI method is 40% longer than the cold process method. Through the second hypothesis, the methods will be compared in terms of price.

An analysis of the price for the cold process method will be made and compared with the actual price from the previous project. The analysis will be carried out using price analyses. The price analyses will be performed on key items or items that differ between the two methods.

Here, it is anticipated that the cold process method will be 30% more expensive than the PZI method. The third hypothesis involves a comparison from an environmental perspective, namely an analysis of the emission of exhaust gases into the environment. This is an analysis that will determine, on the basis of construction machinery and transport, which are key factors for the emission of exhaust gases into the environment.

It is anticipated that the emission of exhaust gases will be 20% higher with the PZI method. In the fourth and final hypothesis, a description will be given of how new technologies can contribute to a more efficient construction process. This topic will be mainly devoted to describing the second method of the cold process.

I believe this would be one of the solutions or methods that could be implemented more in the future, as it would save time and at the same time emit fewer exhaust gases into the environment.
