Description
The 25 procurement procedures for supervision services of railway works (investor's, engineer's and designer's supervision) run by PKP Polskie Linie Kolejowe S.A. under the Polish Public Procurement Law and published on its e-procurement platform, March 2020 to February 2026. The procedures attracted 160 tenders; bid-level records exist for 23 of them (155 tenders, 22 bidding groups). Data for the article "Public procurement of railway infrastructure supervision services in Poland: market structure, pricing and award criteria (2020–2026)" (Janowiec, Ibadov, Kaczorek; submitted to Transportation Research Part A). Files: - procedures.csv: one row per procedure (year, supervision type, financing, award criteria, estimated value, winning bid, budget utilisation, tenders, winner, disciplines). - bids.csv: one row per tender (procedure, bidder, price rank, normalised rank, status). - supervision_procurement_PL_2020-2026.xlsx: th variable definitions. - reproduce.py: recomputes all 84 quantitative statements in the article and checks them against the published values. - README.md: variables, compilation method, limits of anonymisation. Sources: public TED notices, tender opening reports, award notices and procedure documentation. Two duplicates were removed from 27 records. Group companies and consortia count as one bidder. Bidders are labelled Firm A–V and procedures P01–P25. Names, routes, notice numbers, exact dates and losing prices are removed; estimates and winning bids are kept for the budget analysis. The source records are public, so labels are a reporting convention, not a confidentiality guarantee.
