Health & safety software for principal contractors
Managing a construction project means coordinating people, paperwork and site safety all at once. Whether you're delivering a housing development, commercial fit-out or refurbishment project, keeping health and safety documentation up to date can quickly become a full-time job.
Ohutu helps principal contractors create Construction Phase Plans, manage RAMS, organise project documentation and keep everyone working from the latest information throughout the project.

Manage health and safety from one place
Designed for principal contractors managing multiple trades
Because every construction project involves moving parts.
As the project progresses, subcontractors arrive on site, work changes, new risks emerge, and documentation needs updating. Trying to manage everything - from spreadsheets to email attachments - often leads to confusion and duplicated work.
Ohutu brings your health and safety documentation together in one organised system, making it easier to keep project records current and available whenever they're needed.
Support your responsibilities under CDM
In projects involving more than one contractor, the principal contractor is responsible for managing health and safety during the construction phase.
That includes preparing, implementing, reviewing and revising the Construction Phase Plan, coordinating contractors, monitoring arrangements on site, and ensuring relevant information is communicated throughout the project.
Ohutu helps you manage documentation including:
-
Construction Phase Plans
-
Risk Assessments and Method Statements (RAMS)
-
COSHH assessments
-
Site rules and emergency procedures
-
Site induction records
-
Accident and incident records
Stay in control throughout the project
Construction projects rarely stay exactly as planned.
As contractors change, work progresses, or site conditions develop, documentation often needs revising. Ohutu makes it easy to update project information, generate revised documents and ensure site teams are always working from the latest version.

Spend less time repeating administration
Many projects share similar information, from company details to standard working arrangements.
Instead of starting again every time, Ohutu lets you reuse key information across future projects before tailoring documents to suit each site.
This reduces repetitive administration while helping maintain consistent documentation across your projects.
