AAM Group Advances Singapore’s Smart Nation Program Using Open Standards - 1

CASE STUDY '\ Project Summary Organization AAM Group Solution 3D City Modeling Location Singapore Project Objectives • To support a Smart Nation initiative, the Singapore government needed a mobile mapping survey and detailed 3D model of its 5,500 kilometers of roadway, as well as elements along the roadway. • The model needed to incorporate both high-resolution imagery and LiDAR data. • The government wanted to use the model to plan for city growth and maintain a high quality of life for its citizens. Products Used MicroStation®, ProjectWise® AAM Group Advances Singapore's Smart Nation Program Using Open Standards MicroStation and ProjectWise Help to Meet the Requirements of the Singapore Land Authority Fast Facts • Currently, nearly 940,000 cars, taxis, motorcycles, and goods and services vehicles - and a fleet of 18,000 buses enabling 4 million passenger trips per day - are active on Singapore's roads. • AAM Group was awarded the project through a competitive international tender it managed using ProjectWise. • The project scope included procuring a mobile mapping system and using it to acquire and process data for the road network. The effort took about 2,200 resource days, compared to 5,200 resource days it would have taken using other industry-standard software. The team increased its roadway modeling from 1 kilometer per day to 2.5 kilometers per day. All data was maintained in a digital format in ProjectWise, eliminating the need for paper or ink and reducing the project's carbon footprint. Investing in Singapore's Future Singapore is one of the world's most densely populated and infrastructure-rich nations. The Singapore government has introduced a Smart Nation initiative to invest in the future needs of its citizens. The program has at its core a highly accurate, semantically rich 3D digital model, or map, of the entire country, incorporating both high-resolution imagery and LiDAR, and covering all 5,500 kilometers of busy public roads throughout Singapore. To plan for growth, the government needed to better understand its current road network and the connected assets. The Singapore Land Authority, which was charged with creating the 3D map, awarded AAM Group the SGD 4.4 million contract to conduct a vehicle-based mobile mapping survey of the road network and produce highly detailed 3D models of the roads. To meet these requirements with the detail and accuracy required, AAM Group used ProjectWise and MicroStation. A Protracted Project with Complex Requirements The Singapore Land Authority mandated a complex set of requirements. First, the 3D roadway models needed to include all city "furniture" such as bus stops, taxi stands, light poles, traffic signs, overhead bridges, covered walkways, bollards, electrical boxes, manholes, guard rails, and railings. In addition, to make the model future proof and to facilitate easy sharing between government departments, AAM Group needed to provide these models using Singapore Land Authority's preferred, open source CityGML standard. Lastly, the models needed to be semantically enriched and accurate to 0.3 meters. The Right Software for the Job To meet these requirements, AAM Group leveraged the power and flexibility of MicroStation and ProjectWise to implement the right workflows, perform mobile mapping, and manage the project and associated data. The mobile mapping survey of more than 5,500 kilometers of road produced 600,000 million LiDAR points and 3 million high-resolution images. MicroStation provided a framework to easily integrate this data with other available data sources, along with a host of powerful modeling applications to produce the required outputs: semantically enriched CityGML models. The power and flexibility of MicroStation's workflows allowed AAM to realize this goal. Most notably, its flexibility in loading MDL applications enabled the team to create quality assurance routines that assisted with the generation of 3D polygons required to produce high-quality CityGML deliverables, quickly and efficiently. To manage the technical challenges and timeline constraints posed by the project, AAM Group employed ProjectWise, Bentley Systems' collaborative workflow application. ProjectWise was used throughout the project to store vital information relating to subcontractors, invoicing, cashflow, monthly project meetings, and user acceptance testing (UAT) documentation. ProjectWise also enabled seamless collaboration between the AAM office in Singapore and those in Australia - so technical experts from Perth could contribute to UAT documents while finance teams in Sydney could access up-to-date information on invoicing and payments. ProjectWise was also used to store and manage AAM's mobile survey data, which included the high-resolution images and LiDAR points. Configuring Bentley Software for Each Team to Maximize Efficiency AAM's Singapore and Australia offices collaborated using ProjectWise to manage and share data and documents. MicroStation's configurable windows and views enabled AAM's 3D modeling team to set up their workspace to suit the needs of any given feature being modeled, which greatly accelerated the process. To model the road network, AAM's 3D modeling team used MicroStation and the TopoDOT plug-in, which enabled them to model 2.5 kilometers of roadway per day - including curbs, footpaths, median strips, bridges, and green areas. The roadway construction totaled approximately 2,200 resource days using Bentley applications, saving 3,000 resource days had the team used other standard products. Using MicroStation and ProjectWise enabled the team to model an average of 15 pedestrian bridges a day.

"Conducting a mobile mapping survey and then creating detailed 3D models for 5,500 kilometers of road network in the dense, urban environment of Singapore at first seemed like an insurmountable task. The extensive range of modeling tools in BentleyMicroStation combined with the flexibility to build MDLs for specific requirements allowed us to complete this project in an efficient and timely manner. MicroStations powerful display and visualization styles also allowed us to thoroughly check the data, resulting in a high-quality product thatourclientis very satisfied with." - Daniel...
