The 4PS On-site App was specially designed for use on construction sites of non-residential as well as residential building projects. The 4PS On-site App can be used for recording and processing issues for projects, for uploading and sharing documents and pictures of a project and filling in standardized checklists which are sent to the back-office. Since all this functionality is fully integrated with 4PS Construct and the 4PS Document Portal, information is recorded and shared easily and uniformly.
