Features for engineering and planning offices

Mobile Time Tracking for Field Staff

Project hours can also be recorded on the go with the work4all app. The tedious task of entering hours later in the office is now a thing of the past. In the desktop version of work4all, the hours can then be converted into service reports or invoices. Together with external services (incoming invoices), all project costs are visible in real time.

Document management (DMS)

Documents are at the heart of information in an engineering office. All project documents such as reports, plans, photos, etc. are stored clearly in work4all. In the background, files can be stored in standardized project folders on your server. For example, external departments can also store files in these project folders via Windows Explorer and these documents are visible and accessible in work4all.

Project planning with the plan calendar

In internal and customer projects, you plan colleagues, possibly subcontractors, equipment, vehicles and work materials. The plan calendar helps you plan “who, when and where” with tasks, bar chart (GANTT) and scheduling. Your employees automatically receive appointments and can report back work statuses.

Project controlling as a measure of success

In project controlling, as a decision maker, you see external and in-house contributions on a daily basis. This allows you to notice early on whether the project is getting out of hand or whether your planned figures are being achieved.

Recorded project times are compared with the planned values and can be conveniently invoiced at the push of a button.

Communication (CRM) & Document

With your smartphone or tablet, you have all documents with you on the go, allowing you to access site plans, reports, orders, invoices, and more directly on-site at the construction site or in the field. Of course, you can also access the entire project documentation.
