Research data for: Design-flood uncertainty or background-data geography? Which uncertainty reaches the production-stage carbon of a stream-crossing bridge in Türkiye
Year: 2026
Type: dataset
Abstract: Derived research data, model result exports, postprocessing scripts and registers for a production-stage (A1-A3) life cycle assessment of a proposed single-span road crossing over a small stream in the Çatalca district of İstanbul, Türkiye. The study separates design-flood uncertainty from background-dataset choice for one fixed bridge inventory, modelled in SimaPro Craft 10.1.0.4 with ecoinvent 3.9 (allocation, cut-off by classification, unit processes) and characterised with Environmental Footprint 3.1 (adapted) V1.00. 00_foreground: foreground inventory of the reference scenario. 01_results_deterministic: characterisation exports for fifteen configurations, including the three six-item scope expansions. 02_results_montecarlo: summary exports of six paired Monte Carlo analyses (MC1-MC6, 10,000 iterations each), their 1,000-iteration convergence checks, graph-data sheets, and the single-product pedigree run. 03_unit_benchmarks: 1 kWh electricity analyses and library unit factors. 04_literature_search: note only; the database exports are not redistributed. 05_scripts: hydrology reproduction, consistency checks, figure generation and manuscript build. 06_figures: the six article figures and the graphical abstract, PNG at 600 dpi and vector PDF. 08_record_edits: before-and-after comparison of every edited background exchange. 09_registers: parameter register and the prediction log, including the prediction that MC5 and MC6 refuted. NOT INCLUDED ecoinvent 3.9 unit-process datasets (licensed; the files here contain characterised results and process names only); the project design documents, which belong to the public authority that owns the crossing and are available from the corresponding author with the owner's written permission; Web of Science and Scopus record exports (database licence terms); and the SimaPro software and method implementation. See LICENSE.txt. The deposited files contain derived quantities only and do not identify the asset.
