37 Critical document templates for Principal Contractors: User Manual Index

Purpose and outcome (what “good” looks like)

This sheet helps you do two simple things on a notifiable CDM project:

Prepare the key details needed to submit an F10 notification (without hunting through emails later).
Keep a clear record of what was submitted, and make sure the site display copy is current and readable.

Good completion looks like: the dutyholder names and contact details match the latest appointments, dates match the current programme, the submission record is filled in (with the confirmation/reference if you have it), and the site display has been checked and signed.

Who uses it (typical roles)

Role	What they do with this sheet
Principal Contractor (PC) / Site manager	Completes project basics and site display check; keeps it in the site pack; updates it when things change.
Office / Contracts manager	Supports with client/PD/PC details, addresses, and saving the submitted copy in the right folder.
Principal Designer (PD)	Confirms PD details and any changes; may provide the client appointment info and project description wording.
Client (or client rep)	Confirms client details and dutyholder appointments if they change.
H&S adviser (if used)	Quick check that the notification details are consistent with the CPP and appointments; spot-checks display compliance.

When to use it (triggers in the workflow)

Mobilisation / before site start: complete the sheet and submit the F10 (or confirm it has been submitted).
First day on site: put the display copy up and complete the display check/sign-off.
Whenever anything changes: update the F10 (if required), update the display, and record it in the change log. Key triggers include:
- Client, PD, or PC changes (company name, lead contact, phone/email).
- Site address/postcode changes (including unit numbers, plot numbers, or phased sites).
- Start/finish dates move, or duration/worker numbers materially change.
Regular review: as a practical rule, check it at least at weekly site review or every programme update (whichever comes first).

Before you start (info you’ll need)

Gather these first so you can fill the sheet in one go:

Latest programme (start date, finish date, expected duration, key phases).
Correct site address (full address and postcode; include plot/unit/phase if relevant).
Dutyholder appointment details for Client, PD and PC (company names, addresses, main contacts, phone, email).
Scope summary (one or two lines: refurb/new build/roof works, etc.).
Project scale info (max workers at any time, number of contractors, estimated person-days if known).
Where the submitted F10 copy will be saved (folder/path/location) and who will do it.

Tip: If you’re guessing dates or contacts, pause and confirm them. Incorrect details are what normally cause problems on site visits.

How to complete it (step-by-step)

Step 1: Fill in “Project basics”

Use a short, clear project title that matches your order/contract and CPP.
Write the full site address. If it’s a large site, add a simple note (e.g., “Gate A, welfare compound by loading bay”).
Keep the nature of work plain and accurate (e.g., “Office refurb including strip-out, M&E upgrades, partitions, ceiling works”).

Step 2: Complete “Key dates & scale” using the latest programme

Enter the planned start and planned finish as per the programme you’re actually working to.
Put the max workers (peak headcount), not the average.
List the planned number of contractors (including key trades). If unsure, use your procurement plan and update later.
If person-days aren’t known, leave it blank and focus on dates, duration, and peak workers.

Step 3: Fill in “Dutyholders & contacts” and match the appointment paperwork

Copy names and addresses from the actual appointment/contract documents (not just what people call themselves on site).
Use a real contact (someone who answers the phone), and ensure the email is correct.
Make sure the PC site/contract lead is the person a visitor would ask for.

Quick check: the Client / PD / PC details on this sheet should match the CPP front page and any appointment letters.

Step 4: Complete “What was submitted” as your evidence

Record date submitted and who submitted it (name and company).
Record the method (normally online) and any reference/confirmation you receive.
Write exactly where the PDF/printout is saved so anyone can find it fast.
If you have a PDF/printout, attach it behind the sheet (or save it next to the CPP in your digital folder structure).

Step 5: Do the “Site display copy check” on site

Put the display where workers will actually see it (typically welfare, site office, or main entrance).
Tick through each check and add a short note for location if helpful (e.g., “Welfare noticeboard next to first aid poster”).
Remove old versions so there is only one current display.
Complete the checked/updated by sign-off line.

Step 6: Use the “Change log” every time something moves

Write the date of the change and what changed (e.g., “Finish date moved” or “New PD contact”).
Note the new details and who updated the F10/display.
Don’t rely on memory—this log is what shows you stayed on top of changes.

Review and sign-off (what to check)

This doesn’t need a big approval chain, but it does need a sensible check so you don’t display the wrong information.

Check	What you’re looking for	Who normally does it
Dutyholders match appointments	Client/PD/PC names and contacts match current appointment letters/contracts.	Contracts manager or PC
Dates match the working programme	Start/finish/duration reflect the latest programme revision.	Site manager
Display is current	One up-to-date copy is visible; old versions removed.	Site manager / Supervisor
Submission record is complete	Date, submitter, and saved location recorded; PDF attached/saved.	Office / Contracts manager

Escalate if: you can’t confirm who the PD is, the client disputes the details, or the project dates/programme are uncertain. Sort this before (or immediately at) site start.

Recordkeeping (where to store it and how long)

File with: the Construction Phase Plan (CPP) pack and site start / mobilisation records.
Keep on site: one current copy available in the site folder/CPP file, and the display copy up on the noticeboard.
Save digitally: store the completed sheet and the submitted F10 confirmation/PDF in the job folder (same place as the CPP and start records). Use a clear filename (e.g., F10-Details-and-Display-Record_ProjectName_YYYY-MM-DD).
Retention: keep it with the project H&S file/CPP records for the project duration and whatever your normal project record retention period is (so it’s available if queried later).

How often to review or update

Minimum: at mobilisation and first day on site.
Then: whenever dutyholders or dates change.
Practical site rhythm: check it when the programme is updated, and as part of a weekly site review/walkaround (30 seconds to confirm the display is still correct).

Common mistakes (and how to avoid them)

Mistake: Using trading names or nicknames that don’t match appointment paperwork.
Avoid: Copy the exact legal/company name and address from the appointment/contract.
Mistake: Dates on the display don’t match the current programme.
Avoid: Update the sheet and display as soon as the programme changes; use the change log.
Mistake: Display is up, but it’s old, damaged, or buried behind other posters.
Avoid: Replace old copies, keep one clear version, and note the location on the check.
Mistake: No evidence of submission (no reference, no saved copy, nobody knows who did it).
Avoid: Complete the “What was submitted” section immediately and save the PDF in the job folder.
Mistake: Site address missing unit/plot/phase, causing confusion on multi-phase work.
Avoid: Write the full address plus phase/plot and add a short access note.
Mistake: Change happens (new PD contact, dates move) but nobody updates the display.
Avoid: Treat changes as a trigger: update F10 if needed, update display, log it.

Worked example (quick scenario)

Situation: You start a school refurb. Two weeks in, the finish date moves by 3 weeks and the PD changes lead contact.

The site manager updates the Key dates section to match the latest programme revision.
The office confirms the PD’s new lead contact name/phone/email and updates the PD contact section.
You update the F10 details (as needed) and save the updated confirmation/PDF in the project folder.
You replace the site display copy with the updated one and tick/sign the display check.
You record both changes in the Change log (date, what changed, new details, who updated).

Result: if anyone asks on site (client, inspector, worker, visitor), the dutyholders and dates are clear, current, and backed up by a record.
