General contractor seeks construction project software

We are a thriving general contractor for IT infrastructure (internet connections) based in northern Germany and are looking for construction project software tailored to our needs. We operate nationwide.

The software should meet the following requirements:

• Project plans, processes - division into construction phases
• Construction schedule - including the number of planned building or house connections (from private individuals and companies)
• as well as the planned route length in meters
• at least on a monthly basis, preferably on a calendar week basis
• Possibly also the actual number of units/meters achieved for a target/actual comparison
• Alternatively, connection to MS Excel
• Suitable for home office
• Employees of external civil engineering companies must also be able to access it (read/write rights)
• On-premises or web-based

Five software workstations are required at the beginning. We work with MS Windows systems.
