Approx is a construction cost estimation and tender documentation platform that consolidates quantity takeoff, cost estimation, and project-supporting workflows into a single system. It replaces Excel-based, person-dependent processes with standardized templates, formula-based calculations, and automated data flow from tools like AutoCAD. The platform is designed for technical office and planning teams managing multiple projects simultaneously.

Problem
Construction cost estimation and tender documentation workflows are often fragmented across multiple tools like Excel, AutoCAD, and separate reporting systems. This leads to inconsistent standards within teams, heavy time loss during project revisions, and knowledge loss when team members change. Workflows frequently depend on individual spreadsheet structures and manual data transfer, increasing the risk of errors.
Solution
Approx provides a single platform that standardizes quantity takeoff, cost estimation, and project-supporting documentation workflows for construction teams. The platform uses a formula-based structure to convert area, perimeter, height, and similar inputs into repeatable quantity takeoff calculations, enabling high-accuracy cost estimates. Teams can manage revisions directly on top of existing structures without rebuilding reports from scratch, and all work is maintained within a shared company structure to ensure consistent methodology and output quality. Approx integrates with tools like AutoCAD and Excel, allowing data to flow automatically between systems and eliminating manual copying.
Target Audience
Primary users are technical office, planning, and quantity takeoff teams at contractor firms, as well as construction consultancy teams preparing tender files and project-supporting technical documents.
