IN Brief:
- Wills Bros has bought 26 pieces of survey and machine-control equipment for its A9 dualling work.
- The investment supports the Tay Crossing to Ballinluig section, a £257m package within the wider A9 programme.
- Precision survey, machine control, and field software are becoming standard tools on major civils projects.
Wills Bros Civil Engineering has invested in a substantial package of new survey and machine-control technology for its section of the A9 dualling programme, reinforcing the role of digital delivery tools in major civils work.
The contractor has taken delivery of 26 pieces of Trimble equipment supplied through SITECH UK & Ireland, including total stations, GNSS rovers, base stations, and newly released field controllers running Siteworks software. The kit will support the Tay Crossing to Ballinluig section in Perth & Kinross, a £257m package within the wider £3.97bn programme to upgrade 83 miles of the A9 from single to dual carriageway.
Survey, control, and real-time field data are increasingly bound into earthworks, structures, setting-out, quality assurance, and handover. On a corridor scheme such as the A9, where programme interfaces, environmental constraints, and traffic management all need careful coordination, that level of control is becoming central to delivery rather than supplementary to it.
Better positional accuracy reduces the risk of rework and helps keep design intent aligned with site execution. Shared digital workflows shorten the distance between design updates and field activity, while standardised equipment across teams supports consistent data capture over long linear projects. Those advantages grow in importance as infrastructure programmes become more complex and clients place greater emphasis on traceability, quality records, and productivity.
The investment also reflects the way contractors are trying to protect margin on civils packages that remain labour-intensive, resource-heavy, and exposed to delay. Precision technology is often presented as an innovation story, but its value tends to show up in more familiar terms: fewer errors, improved programme control, cleaner records, and more efficient use of plant and labour. On multi-year infrastructure jobs, those gains accumulate quickly.
The A9 remains one of Scotland’s most significant roads programmes, with safety, resilience, and regional connectivity all central to its case. That scale places pressure not just on the main contractor, but on the wider delivery model around materials, plant coordination, environmental management, temporary works, and data control. As machine guidance and digital survey tools become standard across packages of this size, they also begin to influence procurement expectations on future work.
There is a skills dimension as well. Advanced survey and control platforms do not reduce the need for experienced engineers and site teams. They change the skill profile required and increase the value of people who can work confidently with data-rich delivery systems. As contractors and clients expect stronger evidence on as-built quality, carbon, productivity, and compliance, that combination of engineering judgement and digital competence is becoming more important on site.
For Wills Bros, the equipment purchase is directly tied to a live section of a nationally significant road scheme. Across the civils market, it reflects a broader shift in how infrastructure work is delivered. Digital control is no longer there to support the job from the margins. It is part of the production system itself.
