The preconstruction phase of a project is the best time to evaluate options that will add the most value to your project. Too often, this turns into a complicated and contentious process making it difficult to understand progress towards your goals. Join is here to help.

Join presents complicated information in a meaningful, easy to understand format for all stakeholders. By enabling your team to collaborate virtually, you can eliminate disconnected email threads, confusing cost tracking spreadsheets, and separate silos of project information.

Join helps the entire project team

Join is used by contractors, designers, owners and suppliers on any project type, delivery method, or project phase. Regardless of whether optimization for building decisions happens as an explicit value engineering phase or as an ongoing part of design and preconstruction collaboration, Join streamlines that process, enabling it to happen earlier when it can have the most beneficial impact.
