DA10--Intent to sole source Data Aggregator and Viewing Tool

The Department of Veterans Affairs Veterans Health Administration Regional Procurement Office East intends to sole-source a Firm Fixed Price contract to Toth Technology, LLC for development of a web-based data aggregator and viewing tool supporting VA research; responsible sources may submit capability information by 10:00 a.m. Eastern Time on May 27, 2026 to demonstrate alternative capacity to perform the work.

The contract covers four months of performance and addresses a 120-day effort to build a queryable database and web interface enabling VA researchers to access, filter, visualize, and export anonymized subsets of VA-housed healthcare data. The system will handle radiologic imaging (approximately 20.4 terabytes across CT and MRI studies), 45,598 digitized pathology slides (45 terabytes combined), and related research datasets. Work scope includes multi-modality data ingestion and harmonization, schema definition, database loading, a web-based exploration UI with patient indexing and visualization, export functionality, integration testing, and deployment on dedicated Research Scientific Computing infrastructure outside the VA base network. Backend development will use Python, SQLAlchemy, and SQLite/PostgreSQL; frontend will employ Flask, Bootstrap, and Plotly; deployment uses Docker containerization or Podman. The contractor will perform development and testing using publicly available data only, not actual VA data. Place of performance is the contractor's site.

Capability submissions demonstrating ability to perform the Statement of Work must be submitted via email to Mae McGarry, Contract Specialist, mae.mcgarry@va.gov. Telephone inquiries will not be accepted. The Government reserves the right to determine whether to conduct competitive procurement based on responses received and will not fund response preparation costs.
