How to use the LCAT library
Highest visible CALC+ labor title buckets
These are record-density buckets from the public CALC+ API aggregation, not revenue or demand rankings.
This is an observed-title library
Unlike SINs, labor categories are not one official finite list. Contractors define them through their awarded service offerings, duties, qualifications, and rates. CALC+ then exposes awarded ceiling-rate records and aggregation buckets for research.
That is why this page is labeled as CALC-observed. It gives you a broad set of useful role pages while keeping the source language accurate.
Use titles to improve writing, not replace judgment
Recognizable titles help buyers scan a quote, but a labor category becomes useful only when duties, qualifications, price support, and SIN mapping are clear.
The top-15 labor category family pages remain the richer strategy pages. This all-LCAT layer gives each observed title a stable URL and practical starting point.
What this looks like in practice
Example workflowFrom CALC title to usable GSA LCAT
A contractor sees Project Coordinator, Project Manager I, and Project Manager II in CALC+. Instead of copying all three, the team decides which levels it truly sells, writes different duties for each, and supports each rate with commercial evidence.
That creates a cleaner Schedule file and makes future quotes easier to explain.
Frequently asked questions
Does this include every possible GSA labor category?
No. Labor categories are contractor-defined, so there is no single official closed list. This library uses a broad CALC+ aggregation pass and can be expanded with more observed titles over time.
Why keep the top-15 labor pages if this all page exists?
The top-15 pages are richer role-family guides. The all page provides breadth and stable URLs for many exact observed titles.
