Modeling pilots in Espoo

The five city centres of Espoo are Leppävaara, Tapiola, Matinkylä-Olari, Espoonlahtiand Espoo Centre, each of which is the equivalent of a medium-sized Finnish city. Each has developed its own features and services.

Due to Network-like urban structure of Espoo, the City modeling pilots has started on central areas by the project managers with different techniques.

Infrastructural information modeling started on a Pilot Project 2010–2014.

Infrastructural Information Modeling in EspooInfraFINBIM-pilots 2010–2014

Espoo had four different pilot construction with four consults and four planning softwares. Designing the project using datamodel from the beginning to very end had clear benefits but design phase took longer than before because the technology was new and every detail had to be done carefully.

- Information would transfer from the designer to the work machine.- Benefits in quantity calculation.- Chauffeaur wont’t be any more digging too much or too little.- No survey stakes on the construction site and land .- Surveying personnel is not needed as much as before. - Excavator operators don’t have to wait for surveying.

Target - Source infomation model of the city (for infrastructural information modelling) will be ready in 2015 - In year 2018 70% of the new starting road planning projects are based on information modeling and part of the staff will be capable of checking the produced models.Maybe the models can be used in townplanning also

Datamodel project, Espoo technical field

In the project will be clarified the type of a 3D city- and datamodel that are needed in Espoo. One part of project was to explore the big building companies to see how they use BIM models and ifEspoo could take advantage of those models. And could we in turn be able to produce usefulinformation for the companies in the future.

Targets

• Find out how BIM-models could used in the building control• Test IFC modes in Tekla Field 3D (iPad)• What kind of initial data is needed for datamodel based design (for example maps of Espoo and

point clouds)• Test IFC models with Espoos cad-systems and solve difficulties with coordinate systems

Building site uses building information modelin different ways for example in checking thatthe project is running in schedule and cheking details with tablet and Field 3D.

Could this be future in a city scale?

The use of 3D models3D has been used for years in single projects, but there is no standard way to use 3D data. There is no city model of the whole city and no open d ata yet.

• Visualizing urban landscapes , how the building fits in the terrain, massing, connections, townscape• Models for marketing of the local center development, videos etc.• Point clouds , terrain model, sections, floodmaps, models of traffic design and street planning, noise

analysis, landscape analysis, slope analysis, insolation, green areas, single trees, walls, levels and views etc.

• Analysis of the solar potential• Other users like the Aalto University• Maintenance manual of the new Western Metro line is a Virtual Map model

VIREsmart Project Pilot Finnoo (VIrtual REality smart) Janne Porkka, Technical Research Centre Of Finland VTT

Espoo participated the VIREsmart project and we tested how to use models in meetings. Project will develop an interactive participatory design practise approach to allow for extensive sustainability assessments in early planning and design phases.

Espoo had a pilot area in Finnoo and we used virtual city models and new simulation and visualisation technologies in meetings. VIREsmart team collected feedback.In Espoo we can use Urban Mill cave and 3D-glasses. Urban Mill is Co-working and Co-creation Platform Prototype for Urban Innovations in Otaniemi.

Descartes Scalable terrain model and slope analysis and 3D vector models of buildings automatically over the whole city. Around 15 planners can use 3D features of the program.

City of Espoo has increasing population of a Siberian flying squirrel, which is considered vulnerable within the European Union, within its city structure. This squirrel species has characteristic way to move, it glides from tree to tree, and avoids ground.

All trees in Espoo have been laser scanned, and collected data is now used to find possible connections via mass calculations. Special emphasis in given on gliding connections over main highways or other bottleneck places.Photo: Ympäristötutkimus Yrjölä

Energy Information Service (EIS)Espoon energiatietopalvelu http://energiatieto-2-0.herokuapp.com/

The Energy Information System is a browser-based service that compares forms of energy targeted for those considering switching to renewable energy.

EIS offers background and cost information and is based on solar energy analysis created with LiDAR and the weather data. EIS also consists of geothermal analysis combined with a soil map and soil and bedrock data.

In 2012, of Espoo’s total emissions, 70% were caused by heating and electrical energy for buildings. The energy solution can be optimized for each property. SEES data is available as open data for professionals

Model is integrated with LOUHI service of the company SITO, in which there is all kind of project data for builders and contractors of the new Tapiola centerUser can explore current situation in the model or vision 2020 by using timeline.Model provides a possibility to compare different scenarios.Web feature service is used to collect data from Cadastral registry of Espoo. (SITO company: infrastructure, traffic solutions, logistics, land use, environment and digital services)

Mission Leppävaara, pilotCity planning interaction in a virtual city

CityPlanner is a web based service for 3D visualisation of projects.The virtual model of Leppävaara helps picturing the area’s planning and construction projects as well as their preliminary ideas.

The main goal is to get city residents involved in city planning and the discussion that takes place on that topic. The city residents can make suggestions and support the ideas of others.

The Leppävaara city planning team will also follow the suggestions and go over them and answer questions on the Facebook page of the service.

GlobeSpotterBLOM panoramic images of Espoo

GlobeSpotter is an interactive web-based application that provides access to CycloMedia’spanoramic street level images, known as Cycloramas covering the whole city.It can be opened in Espoo’s own Webmap service and can be used to measure heights etc. Easy to check how the building really looks like.

Locus Sketchup exportCity map to 3D model?

Trimble Locus - geographical information database, cadastral data and maps etc. in Espoo.Sketchup-export makes 3D model, and adds register data to building components. It’s also possibleto export cables and pipes, rocksurface etc. Export can place all lines, regions, and maps on top of the surface and thematic models can be made according to the register data.The model is located near the zero, but the location is defined for Google Earth (lat, long)

Skethcup component dataExport use the buildingID, base- and rooflines to make the building model. Sketchup has a Generate Report –function, which can be used to calulate building volumes in the model.

Sketchup export…many questions …

The roof lines has to be checkedHow to add wall textures to these models?Possibility to give z to lines?Could the models be published as open data in Espoos Map Service?How the rocksurface-model can be used? It is not accurate model.Spaces below the ground surface? Ground water surface?Locus 3D development?Web feature service 2.0 and the models?Is the map data the right source data for 3D city models? Or laser data?Do we have to change our process of maintaining maps?Who owns the city model in Espoo?How we add building ifc and infrastructural model to these models?How to get ”as built”- models?

Ideas of the city model

• The Goal is to make 3D information city model of the whole city. If citygml will be chosen as standard in Finland the sourcedata should come from Trimble Locus which is the cadaster and mapping system in Espoo. Building Control Centre could receive ifc-models

• Espoo should maintain the city model and take careof the distribution of 3D city contentsComplexity of the city model makes it difficult to outsourcemaintenance

• A small team is needed to handle the modeldo conversions and help staff to use the city model
