The main motivation for the creation of the LRT system is the constantly growing traffic towards the center caused by the increasing number of people living in the peripheral parts of the city and neighboring municipalities making up the Wrocław agglomeration. As an example of an efficient LRT system using a cross-city tunel is the S-Bahn system in Munich was cited, in which the railway tunnel running through the city center determines large flows of passengers and is therefore one of the main means of transport in the entire agglomeration. In the next part, the current state of the Wrocław Railway Junction is briefly discussed, thus showing the city's great potential to create the LRT system. Places where direct access to the railway network should be provided have been indicated. It was proposed to create two cross-diameter routes running entirely from the tunnel. Their course should be dictated by the location of the traffic generators indicated in the article in the center of Wrocław. In the summary, the author presents the benefits of building new routes and mentions the need for the development of the rail transport network resulting from the Wrocław Mobility Policy. The creation of a new route running through the city center would significantly increase the transport attractiveness of the railways, and thus, the new route would be a key element for the creation of an efficiently functioning LRT system in the city and the entire Wrocław agglomeration.

A characteristic feature of the analyzed structures, in contrast to classic bridges, e.g. brick ones, is a very large influence of the soil backfill on in- ternal forces and deformation of the steel shell. Usually, during construction, the stresses in the shell are many times greater than those arising from the operational loads. In the paper analyzes changes bending moments in the steel shell during the operation of the object as a result of deformation occurring during the construction phase. The test results indicate that the bending moments of the steel structure depends on the geometry of the bridge but with a large influence of the technology of the backfill process. The paper presents an algorithm for esti- mating shell shape changes based on displacements occurring in the construction phase. The examples show a favorable reduction of bending moments in shells with a regular arc. An unfavorable geometry for box-shaped shells has been demonstrated. The results of the analy- sis presented in the paper may be the basis for the measurement methodology in the monitor- ing of soil-steel structure bridges, both during construction and in the operational phase.

The attention is paid to the optional ground based on art. 24 sec. 5 point 4 of the Polish Act of January 29, 2004, Public Procurement Law, according to which the contracting authority may exclude from the procurement procedure contractors who, for reasons attributable to them, failed to perform or to a significant extent improperly performed a prior public procurement contract or concession contract concluded with the contracting authority, which led to termination or awarding compensation. In order to be able to use the institution, the contracting party must include an appropriate clause in the contract, providing for the possibility of terminating the contract or awarding damages due to contractor’s non- performance or improper performance of the contract, which is a common practice on the Polish public procurement market. However, in the event of such a clause, the contracting authority is obliged to apply it if the condition is met. The article also describes the self- cleaning institution, derived from art. 57 sec. 6 of Directive 2014/24/EU. The self-cleaning procedure can protect the contractor from being excluded from future tenders. However, In order to take advantage of self-cleaning, the contractor has to admit that non-performance or improper performance of the contract is their fault.
