An Innovative Approach to Permit to Dig

Utility strikes on electrical cables or pipes can lead to catastrophic consequences on your large-scale construction and infrastructure projects.

It’s costly, disruptive and can even be fatal.  

Traditionally, paper-based permit to dig procedures have been in place to control the risks of excavation works. 

But this approach can lead to:

  • Human error
  • Reduced productivity
  • ‘Lost’ documentation
  • A lack of accountability

It doesn’t have to be this way. 

Vislock locks down the permit to dig process with full transparency in relation to allocated roles and responsibilities. This allows the system to be maintained and policed with a simple but smart workflow.

How Can Vislock Help you?

Vislock is the only digital permit to dig app and cloud-based monitoring platform. It has helped countless organisations to improve their permit to dig procedures whilst supporting digital transformation.

Creates a Robust Process

Vislock enables ultimate transparency and traceability, reducing the risk of service strikes.

Improves Collaboration

An app-based system that allows all stakeholders to work together to reduce accidents.

Increases Productivity

No more travelling to sites to obtain signatures. The cloud-based software can be accessed anytime, anywhere.

Simplifies Processes

Setting a defined documentation standard stored in one source location, with set roles and responsibilities.

De-Risks Your Project

Log and track every milestone within the process to reduce risks and create a culture of safety within your organisation.

What Could You Be Saving, Annually, on your Project?

Over the last two years, we’ve supported Hs2 & Fusion in issuing over 5000 permits over this period. The below statistics show a saving to the project.

What people say about Vislock

“The system stores all information so records of signatures/briefings/incidents can be checked even months after the permit has been closed.

This avoids the paper permits being lost on site and all information being lost. It’s quick and easy to use/navigate and could most certainly be picked up by anyone in the construction industry.”

Dan Stanton, Vision Survey

What people say about Vislock

“Having worked with paper permits for well over 15 years, I can only see this being the way forward. Having all the information readily available when the site is potentially 100 miles away is a real benefit – and something I’d suggest to any organisation”

John Aurndell, Vision Survey

What people say about Vislock

“Some of my biggest issues were lost permits, time to print and prepare permit packs and also the quality of the A3 drawings used on sites. Not only does Vislock already solve all these issues but vastly improves available information, time and quality.”

Scott Gizzy, Service Protection and Service Clearance Manager, Heathrow
