Envision is offered as a fully managed service and requires minimal involvement from corporate ICT services. Ennova offers comprehensive implementation support with experienced implementation engineers to ensure clients best leverage Envision’s many benefits. Core system requirements are detailed below. Please contact our team for further information.

Supported browsers

We recommend using the latest version of Google Chrome for the best performance. We also support the following browsers (latest versions):

  • Mozilla – Firefox
  • Microsoft – Internet Explorer
  • Apple – Safari

Supported mobile devices

We support iOS and Android-based mobile devices. To verify the compatibility of specific devices, please contact our support team.

Network connectivity

Download > 2 Mbps
Upload > 0.5 Mbps
Response time to client Envision instance < 500ms

Backup, storage and recovery

The integrity and security of your data are paramount. Backups of project data are captured hourly and retained for the life of the project for all clients. These backups are stored securely within the Amazon S3 infrastructure in Sydney, Australia. Recovery from a backup can be completed in less than 1 hour on request (charged additionally).

Data ownership and retention

Our clients retain ownership of all uploaded and created data within Envision. Envision allows easy download of project snapshots and analytic data exports for storage elsewhere – as frequently as desired. Projects can be archived for easy recall on request once a project has finished. At the end of a project, data and assets can be exported as a series of .csv files with a ZIP file of uploaded assets (eg photos, documents) and generated assets (eg reports, notices).

Security and encryption

All connections with Envision include transport layer security using HTTPS.

External system integration

Envision includes a fully documented ReSTful API and a custom API for specific external system integrations. Many integrations already exist for external systems including planning, finance, document control, correspondence, building information management (BIM) and geographic information systems (GIS).

Release and update cycle

To ensure ongoing compatibility with changing web browsers and mobile operating systems, we constantly update Envision, releasing these updates weekly.

In addition to security updates for web and mobile platforms, and any defect fixes, we also add incremental functional enhancements to meet the evolving needs of our clients.

  • Most updates involve zero downtime.
  • Updates that do require downtime are completed outside of business hours or on negotiation with clients to minimise disruption.


The availability and performance of Envision is continuously monitored. We are proud of our availability record, which typically exceeds 99.95% including planned maintenance and release activities (over a 12-month period).
