Open the form on this phoneWhat should a work completion certificate include?
A work completion certificate should record the project or site, the date, the work carried out, the certificates, manuals and keys handed over, and photos of the finished work. It should list any outstanding items with the completion date agreed with the customer and who will do each one, then record whether the customer accepts the work as complete or with outstanding items, with the customer's name, position and signature and the engineer's name and signature.

Fill it in on a phone or tablet
Your team completes the sign off on site in the SiteSurvey app on iPhone, iPad and Android phones and tablets. The project name and address fill in for them, it works without signal, and it syncs when the device is back online with photos kept against the question they answer.
Customers and subcontractors do not need the app: send them a link and they can fill it in from any browser.
Every question in the work completion template
Customer acceptance at handover: work completed, outstanding items, customer name and signature. 3 sections and 16 questions. Follow-up questions and guidance appear only when an answer calls for them, so the person on site never sees the ones that do not apply.

Work completion FAQs
Can a customer sign off work with items still outstanding?
Yes. The customer can accept the work as complete or accept it with outstanding items. Each outstanding item is listed with an agreed completion date, so the customer knows what they have accepted.
What stops the sign-off contradicting the list?
The form checks the two against each other. If items are listed as outstanding but the customer is recorded as accepting the work as complete, it asks you to change the answer or remove the items. If there are no items but the work is accepted with outstanding items, it asks you to add them.
Who signs the form?
The customer signs to accept the work and the engineer signs for doing it. The form records the customer's name and position and the engineer's name alongside each signature, and if the customer does not sign, it asks why.
Is this the same as a building regulations completion certificate?
No. For work that needs building regulations approval, the completion certificate comes from the building control body, or from the installer if they are registered with a competent person scheme. The form records that a building control or competent person certificate was handed over, but it does not replace one.
Can I use it as a sign off sheet on site?
Yes. In the SiteSurvey app the form works offline, takes photos of the completed work, collects both signatures on the phone or tablet and produces a PDF report or share link.
Can I add my own questions?
Yes. The form comes from the SiteSurvey library as an editable form, so you can add questions such as test readings or a checklist for your trade to suit your jobs.
