As the first company in the Nordic region, consulting group AFRY has used Trimble's unique alignment planning system Quantm to find the optimal road line for a road project. With 100 automatically generated and rated alignment alternatives to choose from, planning time and construction costs are significantly reduced. The environment, culture sites, fauna, urban constraints, etc. were taken into account.
Road alignment is obviously decisive for the total price and quality when new roads are being planned, designed and constructed. But finding the optimal road line is not always trivial. Traditionally it also takes a lot of time and resources, consequently meaning that not all options are being accurately considered. Often assessments are being made, based on experience.
Road 77 for Swedish Transport Administration
So, when AFRY's Hans Forsberg got a demonstration of Trimble´s road alignment planning system Quantm in November 2017, it was decided to test the tool on Road 77 for the Swedish Transport Administration. AFRY won the contract of planning and designing the first stretch of the road, where the corridor was already defined. The road, which passes through diverse terrain with many restrictions, is a 28 km long cross-connection through Uppsala County and Stockholm County, between E4 and E18. A not so trivial project.
Since AFRY locally did not have any relevant road planning resources at the time, it was decided to make use of Norwegian AFRY expertise to find the best road line for the first stretch. Road planner Anders Høie in AFRY Oslo was given the task. He had completed Trimble's Quantm course and had already acquired some experience with the software tool.
