DPWH Infrastructure Transparency Dataset

Dataset Description

This dataset contains comprehensive information about infrastructure projects from the Department of Public Works and Highways (DPWH) of the Philippines. The data is sourced from DPWH's transparency initiatives and includes detailed information about public works contracts, budgets, progress tracking, and geospatial data.

Dataset Summary

The DPWH Infrastructure Transparency Dataset provides detailed records of infrastructure projects including:

• Contract and project identification
• Project descriptions and categorization
• Budget and financial tracking (budget allocation and amounts paid)
• Project progress and status monitoring
• Contractor information
• Temporal data (start dates, completion dates, infrastructure year)
• Funding sources and program details
• Livestream monitoring capabilities for select projects
• Geospatial coordinates (latitude/longitude)
• Regional and provincial location information
• Community engagement metrics (report counts)

This dataset is valuable for:

• Government transparency and accountability research
• Infrastructure project analysis and monitoring
• Budget allocation and spending pattern studies
• Geospatial analysis of public works distribution
• Contractor performance evaluation
• Project timeline and completion analysis

Supported Tasks

• Tabular Classification: Predict project status, category, or completion likelihood
• Tabular Regression: Predict project budgets, progress rates, or completion times
• Geospatial Analysis: Map infrastructure distribution across Philippine regions
• Time Series Analysis: Track project timelines and spending patterns

Languages

The dataset contains text primarily in English, with some project descriptions and location names in Filipino.

Data Splits

The dataset is provided as a single training split containing all available records.

Dataset Creation

Source Data

This dataset aggregates data from the DPWH Transparency Portal (https://transparency.dpwh.gov.ph/), the official transparency platform of the Philippine Department of Public Works and Highways.

Initial Data Source

The original data is published by the Department of Public Works and Highways (DPWH) of the Philippines through their public transparency API:

• Base API: https://api.transparency.dpwh.gov.ph/projects
• Contract Details API: https://api.transparency.dpwh.gov.ph/projects/{contractId}

Data Collection

• Collection Process: Data was extracted using the dpwh-transparency-data-api-scraper by @csiiiv
• Collection Methodology: The scraper employed two approaches:
  • Pagination-Based Extraction: Concurrent threading to fetch bulk project listings across multiple pages
  • Individual Contract Extraction: Detailed retrieval for specific contracts using contract IDs
• Technical Implementation: Uses curl-cffi with 70+ browser TLS fingerprints (Chrome, Firefox, Safari, Edge, Opera variants) to diversify request signatures, with intelligent retry logic and rate-limit detection
• Annotation Process: Data is provided as-is from government sources
• Time Period: Contains projects from various infrastructure years
• Rate Limiting: The DPWH API enforces approximately 300 requests per 10 minutes; data collection respects these limits

Personal and Sensitive Information

The dataset contains information about government contractors and public infrastructure projects. All information is from public government transparency portals. No personal information about private citizens is included.

Considerations for Using the Data

Social Impact

This dataset supports government transparency and accountability by making infrastructure project data accessible for analysis and monitoring.
