In pursuit of greater productivity, Per Aarsleff adopted data-driven progress tracking on an 8,000 sqm (86,000 sqft), nine-floor head office project in Aarhus, Denmark. With Buildots, the team gained clear, objective visibility into site progress, helping uncover hidden costs and on-site inefficiencies. This approach made it easier to spot issues early, improve overall performance, and reduce the risk of delays, marking a shift toward more data-driven construction management.
Challenge
Per Aarsleff implemented Buildots to achieve three key objectives and structural changes in their on-site work processes:
- Improving workflow efficiency by proactively addressing incomplete tasks, thus preventing potential disruptions and keeping the project on track
- Elevating stakeholder collaboration and enhancing subcontractor accountability and transparency
- Resolving claims, which can escalate into costly disputes and financial losses
“Claims are a big concern for everyone trying to lift off a project. Unfortunately, they often aren't well-documented. But using Buildots, we have real numbers and historical data to oppose or validate those claims.”
Martin Weier Christiansen , Project Director | Per Aarsleff
Solution
Following a thorough evaluation, Per Aarsleff implemented Buildots to bring greater control and clarity to site operations. By combining progress tracking with advanced data analysis, teams were able to move from reactive management to a more proactive, performance-driven approach. Here's what changed:
- BIM-to-reality alignment: Real-time detection of discrepancies between design and as-built conditions ensured issues were identified and addressed early
- Stronger trade management: Progress data was integrated into handovers, ensuring tasks were verified and complete before sign-off, reducing rework and return visits
- More informed planning: Objective data improved the accuracy of work planning meetings, enabling better coordination and more reliable short-term plans
- Greater transparency in claims: Verified, data-backed progress created a clear basis for resolving disputes and managing subcontractor performance
“By pinpointing model discrepancies in real-time, we've really leveled up our proactive approach – it's not just about finding errors; it's about adjusting and optimizing before they impact the project's trajectory”
Mette Mikkelsen, VDC Manager | Per Aarsleff
Results
Buildots helped Per Aarsleff strengthen collaboration and stay in control of project delivery. By identifying scheduling conflicts early, the team was able to mitigate risks that could have delayed the project by over six weeks.
Acting on these insights also helped avoid potential daily fines of up to 0.1% of the contract value, protecting both schedule and cost performance.
Per Aarsleff A/S, a leading EU civil engineering firm and Denmark’s largest contractor with an annual turnover of £2.3 billion, has strategically expanded its expertise from traditional civil and groundworks into more complex urban building projects.
