WHAT IT DOES
REGULATION 12
AI drafts all twelve sections of the construction phase plan from what you already know about the site: the team, emergency arrangements, welfare, hazards and high-risk work.
REGULATION 13
A branded site induction is built from the plan: who is who, site rules, golden rules, the site map, emergencies, the nearest A&E with directions, welfare and PPE.
REGULATION 15
Upload a contractor's risk assessment and method statement and AI checks it against your checklist: a clear rating, critical items missing, omissions and best practice.
SCHEDULE 2 AND PART 4
A QR poster at the gate signs workers and visitors in and out on their phones, with the site address, what3words, grid reference, first aiders and the weekly fire alarm test.
PART 4
The day-to-day records of a construction site, kept on the day they happen.
REGULATION 12(5)
Set out the way HSE's L153 guidance describes, with AI drafting the empty sections when the plan is made. Drawings and certificates drop into the right section as they arrive.
BUSINESS CONTINUITY
Every site has an Excel workbook with locked headings and drop-downs of your workers, contractors and toolbox talks. Record sign-ins, inductions, briefings, toolbox talks, site checks and incidents, then import it when you are back online. A preview shows what will be added before anything changes.
Each part of a CDM Site answers a duty of the principal contractor under the regulations.
| Duty | Where in CDM 2015 | In Assuraz |
|---|---|---|
| Notification (F10) | Regulation 6 | Site tab, with the F10 and the noticeboard |
| Pre-construction information | Regulation 4 | Items requested and received, with files |
| Construction phase plan | Regulation 12 | Drafted by AI, approved and versioned |
| Site induction | Regulation 13 | Slides, video and an offline copy |
| Contractors and their RAMS | Regulation 15 | Appointments, AI RAMS checks, competence |
| Welfare and site checks | Schedule 2 | Daily and weekly checks with a wall poster |
| Emergency arrangements | Part 4 | Alarm, assembly point, first aid, hospitals |
| Temporary works | Regulation 19 | Register and item records |
| Consultation and engagement | Regulation 14 | Briefings and toolbox talks |
| Health and safety file | Regulation 12(5) | L153 sections, built as you go |
Our estimate for a 20-week site with 60 workers and 8 contractors: about 210 hours of CDM paperwork by hand, about 46 with Assuraz. That is roughly four working weeks per site.

CDM Sites is an optional add-on to any Assuraz plan. Start a new site from an existing one and its arrangements carry over.
Software that helps the duty holders under the Construction (Design and Management) Regulations 2015 plan, manage and monitor construction work. Assuraz CDM Sites is built for the principal contractor: the construction phase plan, inductions, contractors and their RAMS, site sign-in, checks, permits, temporary works and the health and safety file, site by site.
Yes. AI drafts all twelve sections from the information you enter for the site. You stay responsible for it: you check it, edit it and approve it before the construction phase starts, as regulation 12 requires. You can also upload a plan the client has already approved.
Upload the contractor's RAMS as a PDF, Word file or image. It is checked against your own checklist and given a rating, with any critical items missing, omissions and best-practice suggestions. A competent person in your team makes the decision to approve or reject it.
Yes. Workers scan the QR poster at the gate with their phone camera and sign in on a web page with the code on their site pass. A tablet can also be used as a sign-in kiosk.
Each site has a business continuity workbook in Excel, with locked headings and drop-downs of your workers, contractors and toolbox talks. Record sign-ins, inductions, briefings, toolbox talks, checks and incidents in it, then import it when you are back online.
In Microsoft Azure's UK South region, encrypted in transit and at rest, with multi-factor sign-in for every user.
