A BC3 manager for real work, not just file viewing.
BC3 files often end up in desktop tools, shared folders, or spreadsheets. Omnicost turns them into an operational database you can search, edit, reuse in projects, and compare against current prices.
Upload price banks, estimates, or ZIP files containing BC3 data. The parser reads encoding, currency, concepts, texts, specs, entities, and measurements.
Every line item keeps its children: materials, labor, machinery, indirects, waste, factors, yields, and order.
Turn the BC3 into a private catalog: normalize units, search items, compare prices, and reuse resources in new projects.
Deliver estimates as PDF, Excel, or BC3 and expose items through API/MCP for agents, integrations, and internal workflows.
What a modern BC3 management tool should do
It does not flatten BC3 into a price table. It keeps the technical recipe behind each construction unit.
Find items by BC3 code, summary, unit, resource, chapter, or long description.
Compare file prices against the live catalog and flag stale or out-of-range line items.
Keep your private items separate from the public catalog for internal project and reference management.
Import FIEBDC-3 and export BC3 to keep working with Presto, CYPE, Arquímedes, or existing workflows.
API, MCP, and webhooks connect the BC3 catalog to AI agents and internal tools.
FIEBDC records Omnicost understands
This page targets BC3 management searches because the product works with the standard structure, not just the file extension.

Coefficients, decimals, taxes, and calculation parameters.
Concepts: chapters, line items, materials, labor, and machinery.
Parent-child decompositions with factors and yields.
Detailed measurements with units, dimensions, and comments.
Long descriptions, technical text, and specifications.
Entities, suppliers, and document references.
Waste classification and waste decomposition.
Common BC3 and FIEBDC-3 questions
What is a BC3 file?
BC3 is the FIEBDC exchange format for construction price databases and estimates. It can contain chapters, line items, decompositions, measurements, descriptions, specifications, and entities.
Does Omnicost replace Presto or CYPE?
Omnicost focuses on managing, normalizing, searching, and connecting BC3 data with projects, private databases, live prices, and APIs. It can coexist with traditional tools through BC3 import and export.
Can I manage my own items?
Yes. The workflow separates the public catalog from your organization's private data so you can manage databases, projects, and internal references from the dashboard.
