Catalog Overview

The Catalog is the backbone of Darwin’s cost intelligence system.
It contains all the reusable building blocks that define how your organization understands construction:

  • Materials
  • Labor
  • Expenses & Logistics
  • Modules (your Cost DNA)
  • Classifications (UniFormat, MasterFormat, IFC context)

This section explains how the Catalog works, why it matters, and how each component contributes to consistent, structured, and transparent estimating.


Traditional estimating tools often bury critical information inside spreadsheets.
Each estimator ends up rewriting the same structures:

  • material lists
  • crew compositions
  • production rates
  • system definitions
  • indirect cost templates

Darwin solves this by turning all of that knowledge into reusable, standardized components.

The Catalog ensures that:

  • estimations are built on consistent assumptions
  • teams share the same construction logic
  • updating prices does not break logic
  • new estimators onboard faster
  • cost data becomes an asset, not a liability

The physical components of construction: concrete, rebar, drywall, windows, etc.
Each material includes:

  • unit of measurement
  • default cost
  • supplier information (optional)

Trades and production rates, including:

  • hourly cost
  • trade classification
  • optional productivity assumptions

Indirects and operational costs, such as:

  • general conditions
  • handling and warehousing
  • transportation rates
  • distance tiers

These help ensure that estimates reflect real-world jobsite conditions.

The most important part of the Catalog.

A Module is a reusable assembly that represents how something is built — a masonry wall, a slab, a footing, a door, a window system, a beam, a partition, a façade panel.

A module contains:

  • materials
  • labor
  • expenses
  • documentation
  • classification tags
  • optional IFC context

Modules define construction logic — not prices.
Prices come from the price list assigned to the project.


When you create an estimation:

  • modules bring construction logic
  • materials and labor flow into cost breakdowns
  • expenses apply automatically
  • price lists update the numbers
  • IFC mapping assigns modules to building elements

The Catalog ensures that the same structure is applied consistently across all projects.


To get the most out of Darwin:

You can expand complexity over time.

Modules define how you build.
Price lists define how much it costs today.

Include notes, drawings, or specifications where relevant.

This makes searching and filtering easier across projects.
