Build with Intelligence. Stralos is a commercial construction workspace for tendering, estimating, quantity takeoff, contract documents, and project cost control. It brings the estimating workflow into one place: projects, documents, rates, activities, work items, and TAGs.

Estimator workflow

Move from project setup through documents, takeoff, work items, pricing, and TAGs.

Getting around

Learn sign-in, navigation, the project selector, and project context.

Manager workflow

Review portfolio status, estimate readiness, pending document suggestions, pricing risk, and margin signals.

Reference libraries

Maintain the reusable rate, supplier, location, and activity data that powers project estimates.

Administration

Support sign-in, pricing defaults, project setup, and controlled reference lists.

Product areas

  • Dashboard: portfolio-level visibility across projects and estimates.
  • Resource library: labour, plant, materials, disposal, suppliers, and project-specific overrides.
  • Activities & Assemblies: reusable build-ups made from rate items and child activities, and materials-only assemblies for one counted unit.
  • Estimate workspace: project documents, takeoff, work items, TAGs, and pricing.
  • Document AI: scan, parse, summarise, classify, and generate suggestions that users review before anything is applied.

Where to start

If you are estimating a tender, start with Getting started. If you are setting up shared commercial data, start with Rates, Activities, and Reference lists.
