How civil engineers implement projects faster, cheaper and safer with SitePlan.
The challenge of civil engineering
Paper plans, tape measures and measuring wheels are still part of everyday life on construction sites - and at the same time major cost drivers.
Typical problems:
- Complex localization and staking out on the construction site
- High external surveying costs and dependence on surveyors
- Missing or incomplete building documentation
- Delays and rework due to analog processes
SitePlan solves these challenges with an app that combines GPS-based navigation, centimeter-accurate surveying and digital construction documentation - directly on your smartphone.
Three projects from Austria and Germany, in which leading construction companies are successfully using SitePlan, show how this works in practice.
Project 1: Renovation & expansion of the wastewater and water supply system
Location: Spittal an der Drau, Austria
Company: STRABAG
Client: Municipality of Spittal
Initial situation:
Several kilometers of pipe network had to be renovated and extended. Previously, this required surveyors, paper plans and time-consuming stakeout work.
SitePlan functions used:
- Localizing & marking cables
- Staking out new line routes
- GPS Photo Documentation
- Digital inventory of fixtures
- Field dimensions
Result:
Faster setting out without external surveyors, complete digital documentation and direct synchronization with the office.
Project 2: Deutsche Bahn broadband expansion
Location: Germany
Company: DB Bahnbau Group
Client: DB Network
Initial situation:
Several thousand kilometers along the rail network had to be inspected and documented for the broadband expansion.
SitePlan functions used:
- GPS photo documentation of the inventory
- Recording local conditions
- Measuring & marking of new buildings
Result:
Seamless digital recording over long distances, simplified collaboration between field service and planning team, less rework.
Project 3: Flood protection Schärding
Location: Schaerding, Austria
Company: PORR-SWIETELSKY consortium
Client: Stadt Schaerding
Initial situation:
Construction of 1,100 m of flood protection walls and dams, including sheet piling, drainage pipes and sewer lines.
SitePlan functions used:
- Staking out earth dams, foundations & sheet pile walls
- Clearing work & canal routes
- Localizing & marking cables
- Inventory
- Digital field measurements
Result:
Reduction of external surveying costs by up to 80 %, faster construction progress thanks to direct staking out on site, complete as-built documentation for clients.
Why SitePlan?
The examples of STRABAG, DB Bahnbau and the PORR-SWIETELSKY consortium demonstrate this: With SitePlan, even complex infrastructure projects can be implemented much more efficiently.
Instead of paper plans, a measuring wheel and external surveyors, a digital solution is used that foremen and site managers can use directly. without training, at any time and on their own devices.
The joint results from all projects:
- 80 % less external surveying costs
- 94 % Time saving for line markings
- 5x faster field measurements
- 70-80 % less cable damage
- Immediate availability of all data for the office and construction site
The bottom line: less waiting time, lower costs, greater precision - and documentation that is always to hand.
