“…A main idea of the new BIM based process was to utilize mobile laser scanning method for initial data acquirement, the use of novel 3-D analyse and modelling methods for point cloud processing, the use of new type optimization method for the planning of geometric and structural improvements needed for the existing uneven road surfaces, and further, through the creation of 3-D machine control models to apply the newest 3-D machine control systems for continuous 3-D control of practical construction work using milling machine and asphalt paver. (Heikkilä et al 2013) The main differences between the absolute and relative optimization methods are described in the These points create a new relative surface that has the key information about the local unevenness of road, which can further be used, through design and construction, to the geometric improvements of the asphalt surface. At the machine control phase, the machine control can be done using the real available road surface on-site as an absolute reference surface.…”

“…In Finland, as a part of the Infra FINBIM research work packet a special effort to study and develop the process of road maintenance has been active since 2010. (Heikkilä et al 2013) Heikkilä et al (2010) have performed a calibration for a stop & go scanning system developed in Finland for the geometric surface measurement tasks of existing roads. When using 20 m vehicle stopping intervals, the accuracy of the measurement was -1 mm ± 8 mm (average, standard deviation), and with 30 m intervals -3 m ± 9 mm.…”

Different possibilities to utilize information modelling and automation in roadway maintenance and renovation, have been studied in Finland during 2010 -2014. Mobile laser scanning was used for the initial data surveys. For the surveys and later design and construction phases, there are generally two alternative methods available for the executions: absolute or relative optimization.In the absolute method, coordinates xyz are accurately measured in relation to the used global coordinate system using reference signal points with appropriate intervals. In the design phase, the absolute point cloud enables the geometric optimization of the whole length of the road. In the construction phase, machine control can be done using automated 3-D machine control system in the global coordinate system.In the relative method, coordinates xyz are measured in relation to the existing road surface without using any reference signal points. In the design phase this relative point cloud enables the specific optimization for each of the selected road parts having some unevenness to be fixed. In the construction phase, machine control can be done using a guidance principle, where a human operates the machine and the blade using a tablet userinterface with RTK-GNSS positioning showing the XY positioning of the blade and the needed asphalt fill or milling cut in z direction.The experiments of the relative method were made in real construction projects of Vt6 (Koskenkylä -Kouvola) and Kt55 (Porvoo) in Finland during 2013 -2014. According to the achieved results, the relative optimization method is accurate enough for the renovation needs of local unevenness of roads. It is much cheaper than the absolute method and the material savings are remarkable compared to the traditional method, where no surveyed information is used. The relative method does not apply to the road parts, where absolute geometry dependences are critical.

“…The process of road maintenance has been studied and developed within Infra FINBIM research package in Finland since 2010 [15] One example of the benefits caused by initiation of national requirements was a large research and development scheme of BIM application in road engineering, performed within strategic program RYM PRE Infra FINBIM in Finland [15]. The goal of the performed project was the utilization of a mobile laser scanning method to obtain the initial data for model generation, testing and development of novel 3D analysis and modeling methods for point cloud processing, applying optimization method for the planning of geometric and structural improvements needed for the existing uneven road surfaces and creation 3D machine control models using machine control systems for continuous control of practical construction work using a milling machine and an asphalt paver.…”

-The current urbanization, industrialization and planning of new city-districts require efficient design to manage the energy, ecology and economical demands set for living environment. The efficiency of Building Information Model (BIM) design in construction sites has been proven through many projects. The full overview and control of design, construction and life-cycle of a structure brings sustainability to buildings and provides optimized purpose for their use. Residential and nonresidential buildings, bridges and other civil and structural engineering products will adopt BIM next to benefit from advanced control of infrastructure and related services.Road design is a complex process requiring collaboration in planning, designing, constructing and execution of designs. The design must consider soil investigations, infrastructure planning, various ecologic aspects and the construction designs to achieve the set durability and efficiency goals. This includes the economic implications and planned maintenance during the entire life-cycle of the construction. The impacts of these features could be improved by detailed analysis and monitoring of the physical behavior of the structure during construction and operative use. The physical performance of the structure may be efficiently analyzed by using numerical modelling, such as Finite Element Analysis (FEA). Integration of FEA in the BIM of road design may significantly improve the road construction and its features during the entire life-cycle.The presented paper discusses the possibilities to improve the road designs via applying FEA tools in information model data exchange. The actual on-site monitoring and analysis would improve the quality of the road building and support its efficient and timely maintenance. Active and detailed collaboration of architects, engineers, constructors and facility managers could yield to efficient and sustainable designs and significantly improve the quality of current and future plans.
