Built by a builder, for builders
The Site Book was created by Nicola Dobbie — a builder who has worked across domestic housing, industrial projects, council contracts, and principal contractor roles. She built The Site Book because the existing compliance tools were slow, expensive, and clearly not made by anyone who had actually been on site.
“I spent more time fighting Word templates than actually managing sites. Builders deserve tools that work as hard as they do.”
— Nicola Dobbie, Founder
Frequently Asked Questions
Is AI-generated content accepted by HSE and principal contractors?
Yes. Every document follows CDM 2015 structure and references HSE guidance (L153, INDG411). The AI generates site-specific content — not generic templates — covering all the sections inspectors and principal contractors expect. You can review and edit everything before downloading.
What happens to my data?
Your project data is encrypted in transit and at rest, stored in the UK, and fully GDPR compliant. We never sell your data or use it for advertising. You own your documents and can export or delete your account at any time.
How long is the free trial?
Your free account lets you create one project with full access to every feature — no time limit, no credit card required. You only pay when you choose to upgrade for unlimited projects. There are no surprise charges.
What happens at the end of the trial — will I be charged?
No. There is no automatic billing. You only pay when you actively choose to upgrade to a paid plan. If you never upgrade, your free project stays yours — no surprise charges, no hidden fees.
Who needs a Construction Phase Plan?
Under CDM 2015, every construction project needs a CPP before work begins. For domestic clients, the contractor takes on this responsibility. For commercial projects, the principal contractor prepares the CPP.
What does the CPP include?
Project details, management structure, site rules, arrangements for controlling significant risks, welfare facilities, emergency procedures, and monitoring arrangements. All sections required by CDM 2015.
Can I use this for domestic client jobs?
Yes. For domestic client projects, the contractor has principal contractor duties including preparing the CPP. The Site Book handles this automatically based on your project type.
How is this different from a free CPP template?
Free templates are blank forms you fill in yourself. The Site Book generates a complete, site-specific CPP from your project details — saving you hours of work.
