Our Data & Methodology
BiharInfraTales is an independent, open-data platform. Every figure on this site is manually compiled by our data team directly from an official government portal — not estimated, and not crowd-sourced. This page explains where the data comes from, how often it's reviewed, and how to report a correction.

How data is collected and kept current
Our data team manually reviews each source portal listed above and records the details as published there — no figures are estimated or extrapolated. Portals are checked on a schedule matched to how often the underlying government source itself changes — tenders multiple times a day, since they open and close on tight windows, and slower-moving records like project status or cabinet decisions on a daily cycle.
Every entity page (tender, project, MLA, minister, cabinet decision) links back to what is publicly known about its source and shows the dates as recorded there — so any figure on this site can be checked against where it came from.
Frequently Asked Questions
- QWhere does BiharInfraTales get its data from?
- All data is sourced directly from official Government of Bihar and Government of India portals — including the Bihar eProcurement portal, GeM, RCD PMIS, NHAI, BRPNNL, East Central Railway, the MoEFCC Parivesh portal, MPLADS records, Bihar Cabinet Secretariat releases, and ECI election affidavits. Nothing is estimated or crowd-sourced.
- QHow often is the data updated?
- Our data team checks the tender portals multiple times a day, since tenders open and close on tight windows. Project, cabinet, and clearance data is reviewed and updated on a schedule matched to how often the source portal itself changes, typically daily. Each entity page shows its own status and dates as recorded in the source.
- QIs this an official government website?
- No. BiharInfraTales is an independent open-data platform that compiles and structures publicly available government data for easier search and tracking. It is not affiliated with the Government of Bihar or Government of India. Always verify time-sensitive details (like tender deadlines) against the original source portal before acting on them.
- QWhat if I find incorrect or outdated data?
- Source portals occasionally contain errors, and our team can occasionally miss an update between review cycles. If you spot something incorrect, use the Contact page to report it with the page URL — corrections are verified against the original source and applied.
