    Highway 3 Arolampi Interchange

Project Summary

Project

Commissioned by the Uusimaa Centre for Economic Development, Transportation, and the Environment, Finnmap Infra Oy was tasked with helping design a new connection to Highway 3 via a teardrop interchange in the southern town of Riihimäki, Finland. The project team needed to ensure that traffic during construction remained unhindered while saving time and cost. Finnmap Infra Oy decided to use photogrammetry and other design applications to meet these objectives.

Solution

Finnmap Infra Oy designed and constructed ramps and junctions, which involved relocating a frontage road and constructing a new way for light traffic, including an underpass. Using Bentley software, the team created machine control models to save design time, creating clear designs that also helped save time during the construction phase. These models facilitated effective collaboration between designers and contractors.

Outcome

The machine control models created using Bentley’s integrated applications helped the project achieve five percent cost savings. The models also vastly improved the execution accuracy of all earth-moving works and eliminated the need for grade stakes, which led to lower survey costs. Completed in the end of 2016, the EUR 10.4 million project is helping move some of the heavy traffic from the street network onto the highway. The new interchange is also making it possible to potentially zone new industrial and residential areas in the region. The companies operating in the area will benefit from the improved logistics in and out of the area via the link to Highway 3.

Software

The project team used ContextCapture’s photogrammetry capabilities to monitor construction progress. OpenRoads enabled the team to deliver the road networks through construction-driven engineering, along with all the needed information to support operational workflows. The application also helped define best practices while supporting the exchange of information. LumenRT assisted in creating real-time visualizations of the project site.
