to digitally document the whole project in a state-of-the-art BIM model.


“Because of this collaborative approach, we now have a much better understanding of how to plan and implement large-scale earthworks projects. I think the key lessons have been around the creation of a digital construction approach and mindset.


“Because the whole site used Trimble Business Centre and its Trimble Connected Community, each machine and surveyor operated Trimble rover, were able to feed information into the BIM model from anywhere on the site. This was achieved by using two base stations to cover the whole of the project.


“Because everything was done in real time, at the end of every day, we were able to see our progress against plan. This gave us forward insight to plan the arrival of


equipment onto site, schedule works around harsh weather conditions and react immediately to 3D model changes.


“This was particularly important when it came to building up the millimetre accuracy of the sub-base layers of the new road, as compaction levels varied across the site, requiring more material in certain areas. From an earthworks perspective, this meant we were able to move material once and well, placing it much more efficiently.


“In-turn this led to less equipment movements and therefore a much safer site. In fact, the amount of people needed onsite was dramatically reduced, as there was no need for any pegging out or in-situ level checks. Plans were sent remotely to machines and data transmitted back to the office, using the GSM network. “I think for me what really simplified the project was the flexibility of being able to fit the


Trimble system to so many different machines of different ages from different manufacturers. This allowed us to source the right products, at the right price, with the right capabilities to perform the tasks at hand.


“Getting machines fitted with the technology quickly was also important and that was where the support from SITECH field engineers real helped. Along with the technical support from its team at head office in Cannock, we were able to quickly configure units and have them operating onsite in a matter for days.


“In conclusion, I think that right from the start of the project, the digital construction approach really set a benchmark. By modeling earthworks in a BIM style model before work began, the A1L2B team identified where we could excavate and place material across the site.
