  • help_outline Are you facing delays in project payments?

    RT Measurement is one of the software tools we use to provide measurement services. It was developed by us for structural measurement, based on measurement standards and practical experience in Hong Kong. It aims to deliver a user-friendly experience, smoothly handle different measurement stages, and efficiently manage disputed items.

    Drawing and Model
    Excel Breakdown
    • check_circle Structured and clear element naming within formulas for better understanding and traceability
    • check_circle Enhanced inspection experience through quantity-to-drawing linking
    • check_circle Excel reports are supported to enable quantity comparisons in the traditional way across different parties without barriers.

    Presentation is important for quantity auditing. A clear presentation helps different parties trust and agree on the quantities. Diagram views are the most effective way to present them. In RT Measurement, we offer multiple methods to present quantities through diagram views.

    • check_circle Beam R.C. details are among the most complicated drawings. The best way to inspect them is to visualize the quantities in the same diagram for quick and straightforward inspection.
    • check_circle We provide typical detail diagrams to clearly represent reinforcement layouts, ensuring that the quantity breakdown is easily understandable and traceable to the drawing.

    Speed and Efficiency No matter how accurate the measurement is, arguments between different parties are common. It is important not only to provide clear proof and evidence but also to revise quantities efficiently in order to close the project earlier.

    • check_circle Schedule view provides a fast way to revise R.C. data. Once an element on a floor is revised, the change is automatically applied to all similar cases.
    • check_circle Compared to the traditional method of modifying each item manually in Excel, General Notes allow surveyors to quickly update multiple settings at once, greatly improving efficiency.
