Developing a web and mobile safety platform for construction sites

Ohutu, whose name means 'safe' in Estonian, is a UK-based construction technology start-up founded in 2018. Its mission is to simplify and improve how construction teams manage health and safety processes across projects.

The company’s platform replaces complex paper-based systems with a digital solution that allows site managers and supervisors to oversee safety documentation, risk assessments and compliance tasks from a single system.

About Ohutu

Health and safety management in construction often involves large volumes of paperwork, including risk assessments, method statements and construction phase plans. Managing these documents across multiple sites can be time-consuming and difficult to coordinate.

Ohutu set out to create a digital platform that would simplify this process. By combining a central web application with mobile apps for site supervisors, the system enables teams to manage safety documentation and compliance tasks more efficiently.

OWA has worked with Ohutu since its founding in 2018, supporting the development of the platform while also providing secure hosting, system monitoring and ongoing technical support.

The challenge

As an early-stage start-up preparing to launch its first product, Ohutu needed to move quickly from concept to a working system ready for real users. The platform had to support both desktop and mobile environments while providing a clear, intuitive experience for construction professionals working in busy site conditions.

At the same time, the system needed to handle complex workflows relating to health and safety documentation and project management.

Launch a new health and safety platform within tight timescales
Develop a central web application for managing multiple projects
Create mobile apps for supervisors working on construction sites
Replace paper-based safety processes with digital workflows
Ensure the system was ready for both subscribers and app stores

Delivering the platform required a flexible and collaborative approach to design, development and testing.

OUR APPROACH

Our approach

1

Concept & requirements definition

We worked closely with the Ohutu team to shape the product concept and define how the web and mobile applications would support construction safety workflows.

2

UX & interface design

Layouts and interfaces were designed so information could be viewed and managed easily by site supervisors using mobile devices, ensuring a streamlined user experience (UX).

3

Workflow mapping

Detailed process mapping ensured the system supported the full journey from pre-construction planning through to generating construction phase documentation.

4

Web & mobile development

A central web application was developed alongside integrated iOS and Android apps, enabling supervisors to manage safety information directly from site.

5

Launch readiness

The platform was prepared for real-world use, including system stability, subscriber readiness and submission to the mobile app stores.

THE RESULTS

The solution

OWA partnered closely with Ohutu to transform an early-stage concept into a fully functioning digital platform. Early work focused on understanding how construction teams manage safety processes and translating these workflows into intuitive digital tools.

A central web application was developed to allow managers to oversee health and safety documentation across multiple projects. Alongside this, mobile apps for iOS and Android were created to enable supervisors on site to access, update and manage safety information directly from their devices.

The system supports the creation and management of key documents such as method statements, risk assessments and construction phase plans. By integrating the mobile apps with the central platform, site teams can maintain accurate records and manage compliance activities while working on location.

The results

The platform has helped Ohutu bring an innovative construction safety product to market:

Digital platform replacing complex paper-based safety processes
Integrated web application and mobile apps for site teams
Streamlined management of risk assessments and method statements
Flexible system supporting multiple construction projects
Ongoing development, hosting and technical support

Ideas and suggestions we discussed were seamlessly integrated without any unintended consequences. I can’t fault them for speed and quality.
