Who is it for?

Approx creates the most value for these teams

Designed especially for teams managing multiple projects at the same time and looking to standardize quantity takeoff and cost estimation workflows.

Contractor Firms

Technical office, planning, and quantity takeoff teams

Makes Excel-based, person-dependent, and revision-heavy cost estimation workflows more manageable.

  • Cost estimation
  • Budget and planning support
  • Revision management
  • Standardized reporting

Construction Consultancy Firms

Teams preparing tender files and project-supporting technical documents

Helps consolidate project data from different sources and produce more structured, detailed, and standardized technical documentation.

  • Tender file preparation
  • Cost estimation
  • Specification-supporting documents
  • Detailed project outputs

Common challenges

Cost estimation workflows are still fragmented in many firms

Workflows split across multiple tools often lead to inconsistent standards within teams and major time loss during revisions.

📋

Excel and single-person dependency

Quantity takeoff and cost studies often depend on one person’s spreadsheet structure and personal workflow.

CURRENTLY

Work progresses through person-specific files; when team members change, knowledge is often lost.

WITH APPROX

All work is managed within a shared company structure; everyone works with the same standard.

🔄

Rework during revisions

When a project changes, reports and supporting tables often need to be rebuilt manually.

CURRENTLY

When the project changes, reports and tables usually have to be prepared again from scratch.

WITH APPROX

Update quickly on top of the existing structure; revisions do not create a separate workload.

👥

Loss of standardization across teams

When multiple people work on the same project, methodology, quality, and output format can vary.

CURRENTLY

Different people work with different methods; outputs and quality become inconsistent.

WITH APPROX

Everyone works with the same templates and formulas; results become repeatable.

🔗

Disconnected data flow

Moving data between AutoCAD, Excel, reports, and other systems creates additional operational overhead.

CURRENTLY

Data is moved manually between AutoCAD and Excel; the risk of errors increases.

WITH APPROX

Data flows automatically; the need for manual copying is eliminated.

How it works

Manage fragmented cost workflows in a single flow

Approx makes the quantity takeoff and cost estimation process more structured, from data entry to final reporting.

  1. 1

    Create the project and working structure

    Start your project based on your tenant structure and define the necessary templates and work areas.

  2. 2

    Process quantity takeoff data

    Use the formula-based structure to convert area, perimeter, height, and similar inputs into a standardized quantity takeoff workflow.

  3. 3

    Produce cost estimates and supporting documents

    Manage cost estimation tables, breakdowns, and project-supporting outputs within the same structure.

  4. 4

    Manage revisions and generate updated reports

    When changes occur, continue from the existing system structure and quickly reach updated outputs.

Use cases

Maintain the same structure across different project types

Approx provides a standardized and traceable cost production workflow across changing project needs.

Fast standardized production in mass housing projects

Similar room types and repeating building elements make formula-based workflows significantly faster.
