Organisation of a Construction Site for the Project: 'Remediation of Ground Surfaces at Maribor Freight Station' with a Construction Schedule

The aim of the diploma thesis was to produce a construction site organisation project with an emphasis on developing a construction schedule. At the core of the diploma thesis, he examined in detail the construction contract, project documentation and organisational options at the construction site location itself. Using static plans for labour, machinery and materials, he precisely dimensioned the capacity requirements for optimal operation of the construction site in question. Using the network technique for planning works, he determined which works the completion deadline depends on. Due to strong competition and a shortage of work, it is difficult to obtain work that would have reserves, so it is necessary to take into account all the minor parameters in order to achieve successful completion of the structure, for which preparation and organisation of the construction site is essential, as it strongly influences the construction result.

Problem

The aim of the diploma thesis was to produce a construction site organisation project with an emphasis on developing a construction schedule. At the core of the diploma thesis, he examined in detail the construction contract, project documentation and organisational options at the construction site location itself. Using static plans for labour, machinery and materials, he precisely dimensioned the capacity requirements for optimal operation of the construction site in question.

Solution and Method

Using the network technique for planning works, he determined which works the completion deadline depends on. The essence lies in finding the so-called critical path, where we can see where we do or do not have time reserves. In preparing the diploma thesis, he used data from a construction site that he successfully completed, as he observed all the rules and conditions for successful and quality construction.

Results

Due to strong competition and a shortage of work, it is difficult to obtain work that would have reserves, so it is necessary to take into account all the minor parameters in order to achieve successful completion of the structure, for which preparation and organisation of the construction site is essential, as it strongly influences the construction result. In their case, the final result was greatly influenced by good equipment with existing infrastructure, the possibility of carrying out works over larger areas and the proximity of a permanent material depot. With the proximity of the depot, they saved the most during project realisation on material transport and machinery services for depot arrangement.

Due to the later discovery of the possibility of using excavated material, when the investor decided that the material should be deposited nearby, they achieved a good result by using a small number of lorries and complete utilisation. The investor also saved money on the next planned investment that he intended to carry out by later using the excavated material. Likewise, their own production of asphalt mixture played a major role.

Every incomplete or deficient project strongly affects the course of construction and the quality of works execution due to increased costs. In their case, the project was deficient, but it did not cause them major difficulties, as the investor provided additional funds for project realisation and the designer's cooperation was also proper. In addition to construction site organisation, the diploma thesis presents a construction schedule using the network planning technique with corresponding calculations.

The construction schedule shows the critical path, which the works contractor must regularly monitor so as not to fall behind with construction. In most cases, the construction schedule they set held, but during construction additional works or unforeseen works may arise, with which we must revise the construction schedule. Therefore, in many cases there are construction delays and deadline extensions.

During project realisation, a problem arose due to the late introduction of the contractor into the contract in relation to the works completion deadline, which caused works to be delayed into the winter period, in which weather conditions are not suitable for carrying out the planned works. Likewise, unforeseen and additional works appeared, which had to be urgently carried out due to the structure's functionality. Due to the investor's inattention and unforeseen works, construction was delayed over winter and caused additional costs in project execution and made it more expensive overall.

Due to the delay in works, the investor found it easier to provide additional funds that were needed to complete construction. The project cost increase was represented by maintenance and ongoing elimination of deficiencies at the construction site during winter due to partial active use of the platform and snow ploughing. An even greater cost for the investor at this transfer station was represented by the reduction in goods flow in rail transport due to the delay in commencing use of the platform.

For successful completion of the entire structure, a proper and good relationship between the investor, contractor and designer is necessary. Poor construction site organisation typically worsens relations between the parties involved and causes many inconveniences, especially for the works contractor, which is why good planning of construction organisation is so very important. In preparing the diploma thesis, he learned how important a part of construction proper organisation and set construction time schedules are.

Small changes can very strongly influence the final construction result. In practice, we often do not realise how important they are. By preparing the diploma thesis, he refreshed his knowledge and gained additional insight into the method of carrying out everyday professional tasks.

This diploma thesis additionally stimulated in me the enthusiasm for organising construction of individual structures in further work at the workplace.
