Fill it in on a phone or tablet

Your team completes the drainage installation inspection 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 drainage installation inspection template

A drainage installation record linking drawings, pipe and chamber observations, levels, concealed-work evidence, approved test references and defects. 5 sections and 41 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.

Make it your own: every question is editable

This is a starting point, not a fixed form. Once it is in your SiteSurvey account you can reword any question, add or remove questions, sections and answer options, and add your own logo, so it fits the way your team works and the jobs you do.

Details you only enter once

Add this form to a project in SiteSurvey and it fills in what the project already knows, so nobody on site retypes it and every form on the job uses the same names. Anything filled in can still be changed.

Drainage Installation Inspection FAQs

How should I record “As-built record and handover recipient”?

Identify changes from the approved layout and the corresponding as-built reference. Include concealed sections not witnessed as a limitation.

Does this prescribe an air-test pressure?

No. Reference the approved method and separately recorded test result.

How does it differ from the CCTV survey record?

It records installation-stage checks against design; the CCTV record links footage and observed drain condition.

Can a chamber be entered to complete it?

This record provides no entry authority. Record inaccessible areas and use the separately assessed process.

What are the limits of this template?

This is an installation inspection record, not a drainage test certificate, design approval, CCTV condition survey or chamber-entry permit.

Can I complete this form on site and share the record?

In the SiteSurvey app the form works offline, with photos and signatures recorded against the questions. Share the completed record as a PDF or a link. Dates and action owners are recorded fields; this form does not send reminders or update other systems.
