Optimize file management, storage, and sharing in the construction industry
Centralize plans, studies, photos, and as-built records in an environment hosted in France, and share them with all stakeholders, from the design office to the job site.
Brick by brick, we build the sovereign environment you need.
Construction professionals face critical challenges.
A construction project involves years of documentation: plans, studies, contracts, photos, reports, and as-built records. Voltn (formerly NetExplorer) stores and manages them in a sovereign cloud designed to keep pace with the field.

Concrete use cases in construction
Architect & engineering firm
Plans, technical studies, calculation notes, and graphic documents: the design phase generates heavy files that circulate between the agency, engineering firms, project owners, and contractors. Every plan revision sent by email creates a risk of using an obsolete version on site.
Voltn centralizes project documentation: stakeholders always have access to the latest revision, communications are tracked, and large files are sent via secure links.
the construction site +
full traceability
General contracting and structural work
A general contractor coordinates dozens of subcontractors, hundreds of documents, and teams split between the head office and various job sites. Deliverables arrive via email, local servers become overloaded, and a ransomware attack can bring all operations to a standstill. Voltn organizes it all: a dedicated space for each project, an upload link to collect subcontractor deliverables, replicated storage to keep data safe, and mobile access for site managers.
accessible documents
Trades & finishing work
Electricians, drywallers, plumbers, painters: tradespeople work on multiple sites simultaneously, each with different plans, schedules, and instructions. The right document is often buried in an impossible-to-find email or left on a computer back at the workshop. With Voltn, every project has its own shared folder: up-to-date plans and instructions are accessible on mobile, and photos taken at the end of a job are uploaded directly to the right place.
documented interventions
Public works & infrastructure
Roads, utilities, and civil engineering structures: public works projects involve demanding contracts and span many years. Technical reports, as-built drawings, and final project documentation (DOE): every document creates a long-term liability for the company, sometimes for decades. Voltn secures this long cycle: tender documents are sent via secure links with expiration dates, site documents remain hosted in France, and the complete final documentation is delivered upon project completion in just a few clicks, regardless of its size.

Dominique Tessaro
Chief Information Officer at Vinci Energies
We were looking for a document-sharing solution that met our security and privacy requirements, was accessible on the go, and user-friendly enough to prevent shadow IT. Hosted in France and ISO 27001 certified, Voltn was chosen to meet these criteria, notably through its secure SAML authentication.
FAQ
Can field teams access documents?
Yes. The Voltn mobile app provides access to plans, schedules, and instructions directly from the job site, even when offline. Photos and reports are uploaded automatically to the correct folder.
How do you deliver a complete O&M manual upon project completion?
Via a secure sharing link, regardless of the file size. The recipient downloads everything at once, and you retain a timestamped record of the transfer.
How can you keep construction project documents for the long term?
Voltn stores your documents for as long as necessary, complete with version history and an anti-deletion trash bin. For long-term archiving, the Vault option adds immutable backups on LTO magnetic tapes.
How do I send files that are too large for email?
Use a secure Voltn Share link, with no limits on size or format. Blueprints, BIM models, photos, and videos are encrypted in transit, with full tracking of views and downloads.
Where can you securely store construction project documents?
In a Voltn Workspace dedicated to your project, hosted exclusively in France. Every file is encrypted, scanned for viruses, and replicated in real time across three storage systems in two separate data centers.
But let's be honest, our cloud-based file storage and sharing solution is just easier.
