The General Directorate for National Roads and Motorways (GDDKiA) has opened bids in the tender to repair the most damaged section of the A1 motorway near Pyrzowice. Eight entities are competing for the contract to modernize the over three-kilometer stretch where so-called "Danube waves" occur. All bidders stayed within the reserved amount of PLN 63.1 million, with the cheapest proposal amounting to nearly PLN 36.4 million. This is the first stage in combating deformations caused by subgrade swelling.
Eight Bids for A1 Repair
All participants in the tender for the section near Dobieszowice stayed within the PLN 63.1 million budget; the cheapest offer is PLN 36.4 million.
End of Wavy Pavement
The renovation is to eliminate the so-called Danube waves caused by swelling of subgrade materials and restore the road standard for 30 years.
Progress in S11 Project
Five companies submitted bids for the design documentation of a 29-kilometer section of the new expressway towards the Coast.
The Katowice branch of the General Directorate for National Roads and Motorways (GDDKiA) has taken a key step towards solving the long-standing problem of the wavy pavement on the A1 motorway. In the ongoing tender for the repair of an over three-kilometer section towards Piekary Śląskie, eight bids have been submitted. The lowest price, amounting to PLN 36.4 million, was proposed by the consortium of COLAS Polska and ANTEX II. This is a significantly lower amount than the investor's budget, which the contracting authority set at PLN 63.1 million. The most expensive offer, submitted by Trakcja, amounts to PLN 59.3 million. The tender committee is currently analyzing the documents for formal and substantive compliance. The problems on the Pyrzowice–Piekary Śląskie section began shortly after the route was opened in 2012. The characteristic unevenness, colloquially called "Danube waves" by motorists, results from the swelling of materials used in the road's subgrade. Despite earlier attempts at spot repairs, the technical condition of the roadway has been steadily deteriorating, forcing the introduction of speed limits to 80 km/h at the most critical points. The planned renovation is to permanently restore the route's technical parameters for a period of at least 30 years. The construction of the Silesian section of the A1 motorway was one of the largest infrastructure investments after Poland's accession to the European Union, but from the beginning, it faced geological and quality problems on post-mining lands. Simultaneously, GDDKiA is intensifying work on the S11 expressway, which will ultimately connect Silesia with Kołobrzeg. In the latest proceeding concerning design documentation for a 29-kilometer section from the border of the Opole Voivodeship to the Tarnowskie Góry County, five bids were submitted. The most financially advantageous proposal was submitted by the Katowice-based company Trakt, valuing the design work at PLN 12.4 million. This documentation is necessary for the subsequent announcement of a tender in the "Design and Build" formula, bringing the region closer to obtaining a fast connection to the Baltic Sea. „To kolejny krok w przygotowaniach do realizacji tej jednej z kluczowych inwestycji drogowych regionu.” (This is another step in preparations for the implementation of this one of the region's key road investments.) — GDDKiA These investments are part of a broader plan to modernize the Silesian transport hub, also including the announced expansion of the A4 motorway with an additional lane on the section from Gliwice to Mysłowice. The accumulation of these actions aims not only to improve safety but, above all, to increase capacity in the region with the highest transit traffic intensity in the country.
