Introduction to TX1
TX1 is a desktop estimating platform for construction and engineering projects. It brings together cost build-up, markup and margin calculation, apportionment, carbon tracking, and client-ready sell rate reporting in a single Windows application.
What Can TX1 Do?
| Area | Capability |
|---|---|
| Cost build-up | Hierarchical direct cost items with unlimited breakdowns and formulas |
| Resources | Labour, Material, Plant, Subcontract and custom resources; built-up resources compose component rates |
| Overheads | Separate overhead pool with its own breakdown and apportionment engine |
| Sell rates | Automatic markup and margin distribution across items, by resource type, with scenario modelling |
| Carbon | GHG Protocol Scope 1/2/3 emission tracking alongside cost, with verification workflow |
| Formulas | Spreadsheet-style engine with 70+ functions, scoped and global parametrics, dependency tracking |
| Templates | Reusable line-item blueprints with optional embedded resources |
| Master Library | Central organisational repository of resources and templates with sync and versioning |
| Reports | PDF project summaries, dashboard KPIs, portfolio roll-ups |
| Import / Export | Excel, CSV, JSON and proprietary .tx1 project packages |
Who Is TX1 For?
- Estimators building competitive tenders
- Quantity surveyors pricing works
- Project managers tracking cost performance and sell rates
- Sustainability leads reporting emissions alongside cost
- Company administrators maintaining a standardised resource library
How TX1 Thinks About a Project
At the highest level, TX1 separates a job into two cost pools and then combines them:
Direct Costs + Overheads → Total Cost → + Markup → + Margins → Sell Price
(the work) (running the job) (per-type) (risk/profit)Every calculation in TX1 is a transformation within this pipeline. Once you understand where a value sits in the pipeline, the rest of the software makes sense.
What This Guide Covers
Read this guide top-to-bottom to learn TX1 from scratch, or dip into any section. The core recommendation:
- Getting Started (you are here) — orientation.
- Core Concepts — terminology and the cost pipeline.
- End-to-End Walkthrough in section 17 — build one real estimate and everything clicks.
After that, return for deep-dives on formulas, carbon, master library and scenarios.
