Organising successful outdoor events requires detailed planning and collaboration with stakeholders. Often event sites are planned using screenshots from online maps and basic presentation tools. This leads to inaccuracies and a lack of coordinated planning.  

OnePlan is a game changing planning tool for the event industry. It supports event professionals to plan safer events by utilising intuitive space planning and measurement tools within a global mapping platform.  

Reduce the time, cost and stress of event planning

Any area can be plotted onto OnePlan to provide an instant crowd capacity. The tool bar functionality allows planners to drop and drag a huge range of event infrastructure, human resources and supplier products to accurately develop event sites. For example, pedestrian barriers can be plotted onto the mapping system and an instant quantity is shown.  These details can be shared in real time with other OnePlan users reducing the need for excessive planning meetings.


The intuitive measuring tools instantly provide estimate queue length and time. There is an evacuation calculator, which visually displays an estimate evacuation time for people to flow through exit gates.

OnePlan streamlines event procurement by linking planners with suppliers. From the site plans that event planners develop, event-shopping lists are created that can be submitted with one click to suppliers to provide instant quotes. Suppliers have the option to add their own items to a drag and drop menu.
