The Proposal of Patproject 2000 Ltd. is Ranked First in the Competition for Elaboration of an Extended Conceptual Design of Struma Motorway in the Krupnik – Kresna Section
The proposal of Patproject 2000 Ltd. is ranked first in the competition for elaboration of an extended conceptual design of Struma Motorway in the Krupnik – Kresna section. Today at a public hearing in the Road Infrastructure Agency the jury announced the results of the evaluation and ranking of the competition projects and opened the envelope with the list and the numbers of the participants in the competition, which until now were anonymous.
Two bidders have submitted documents to participate in the competition for elaboration of an extended conceptual design of Struma Motorway in the Krupnik – Kresna section, left carriageway, with approximate length of 23.8 km and bypass of the town of Kresna – part of right carriageway with approximate length of 5.45 km. The proposal of Patproject 2000 Ltd. was first ranked with 93,278 points and the second one was Patproject SMLLC with 89.859 points. The project value proposed by Patproject 2000 Ltd for the construction of the section is 732 109 652.44 BGN, VAT excluded, and for Patproject SMLLC the project value is 729 241 729.60 BGN, VAT excluded. The company which offered a higher price has included in its design improvements of the existing transverse links between the two carriageways to the future alignment, the chairman of the jury arch. Petar Dikov, representative of the Bulgarian Transport Infrastructure Forum, explained. The chairman of the jury stressed also that the both conceptual designs were developed at a highly professional level and on their basis in a short time could be prepared the next stage – technical design.
The submitted designs have been evaluated according to a previously announced methodology for calculation of the complex assessment. It includes quantitative indicators, part of which represents the design value of the construction. The project that offers the most safe and sustainable design solution is the highest ranked one. The geological analysis of the terrain which the alignment will pass through is an extremely important component in the preparation and implementation of a complex infrastructure project, such as Lot 3.2 of Struma Motorway. The purpose of the competition is to acquire an advanced conceptual design with detailed geodetic surveying, engineering and geological study and plot plan for this motorway section, on the basis of which it will subsequently be able to award the technical design phase of the project and construction of 23.8 km of the left carriageway of Struma Motorway in the section between Krupnik and Kresna and the 5.45 km bypass of Kresna – part of the right carriageway.
As an innovative solution, the jury highlighted the proposal of Patproject 2000 Ltd. for the construction of a viaduct at km 394+151.90, left carriageway, through a cantilever installation with a central clearance of 302 m. Such facilities are unique, the jury member Eng. Pavel Dikovsky, representative of the Bulgarian Branch Chamber Roads explained.
Both teams have tried to minimize the number of facilities that need to be built, as they would increase the construction cost of the route as volume of investment. Nevertheless, tunnels and viaducts are unavoidable due to the complexity of the terrain through the Kresna Gorge, arch. Dikov summarized. It is proposed to build a total of 7 tunnels – five on the left carriageway of the alignment and two at the bypass of Kresna.
The competition is being hold with awarding of prizes for participants. The prize pool is BGN 2 500 000 for 3 awards – 85% for first place, 10% for second and 5% for third place. The prize fund entitles the employer to use the project.
