Case Study: Sonell streamlines stakeholder communication with GBuilder

Streamlined communication between stakeholders

Sonell, a medium-sized construction company in Oulu, Finland, wanted a better way to manage communication and customer involvement across sales, pre-marketing, construction, and handover. Working with GBuilder, Sonell needed to replace phone- and email-based processes with a clearer, more transparent system that could support homebuyers, site teams, and subcontractors throughout the project lifecycle.

GBuilder provided a BIM-based communication and checklist platform with 3D model selection tools, mobile apps, mass messaging, electronic signatures, and space-specific comments and files. The result was improved transparency, better data quality, faster site operations, fewer mistakes, and a smoother customer experience; Sonell also reported easier confirmation of change orders, more accurate delivery handling, and more efficient administrative work from pre-marketing through annual repairs.
