Built specifically for subcontractors, Onetrace is construction management software that connects job planning, on-site evidence capture, and compliance sign-off in a single workflow. Rather than juggling spreadsheets and paper records, teams get one system covering everything from the first site visit to final handover, with audit-ready documentation ready for clients, main contractors, and regulators whenever it's needed.
The platform supports a wide range of trades, including passive fire protection, drylining, roofing, and M&E. For fire protection specialists in particular, Onetrace works as dedicated fire protection software — linking photographs, sign-off forms, and approvals to the exact job and location they cover, so compliant installations are easy to evidence. Teams also get live visibility of projects, timesheets, signed documentation, and site progress as it happens.
Key functionality: customisable forms, drag-and-drop scheduling, GPS-verified time-tracking, scope variation tracking, cost calculation, and mobile drawing markups with photo capture.

Windows Presentation Foundation (WPF)
Windows Presentation Foundation (WPF) is a framework exclusive to Windows in the .NET ecosystem, utilizing a vector-based rendering engine that is independent of resolution, thereby harnessing contemporary graphics hardware to create visually engaging desktop applications. This framework boasts a rich feature set, including XAML markup, an extensive array of controls, data binding capabilities, layout management, 2D and 3D graphics, animation, styling, templating, document handling, as well as multimedia integration, text, and typography functionalities; it also permits the usage of other .NET APIs. WPF is structured as a collection of .NET types located within the System.Windows namespace and accommodates traditional programming methodologies, such as class instantiation, property modification, method invocation, and event handling, along with advanced concepts including dependency properties and routed events. With WPF, developers have the ability to craft user interfaces declaratively through XAML while executing logic in the code-behind, which not only streamlines the division between user interface and business logic but also enhances globalization efforts and fosters collaboration between designers and developers, making it a versatile choice for modern application development. This dual approach in WPF ensures that both aesthetic and functional aspects of applications can evolve in harmony, ultimately resulting in a more cohesive user experience.

QML
QML is a declarative language that facilitates the description of user interfaces through their visual elements and the relationships between them. This language is designed for high readability, making it easier to dynamically connect components while allowing for their reuse and customization. Leveraging the QtQuick module, developers and designers can craft smooth, animated user interfaces in QML that can seamlessly interface with various back-end C++ libraries. As a specification and programming language for user interfaces, QML empowers both developers and designers to create applications that are not only visually striking but also highly performant with fluid animations. It boasts a declarative, JSON-like syntax that is easy to read, while also providing support for imperative JavaScript expressions and dynamic property bindings for enhanced functionality. Additionally, its flexibility allows for innovative designs that can adapt to different user needs and preferences.
