Project summary

Augmented Reality for Building and Construction (AR4BC)

Charles Woodward, VTT

VTT TECHNICAL RESEARCH CENTRE OF FINLAND

Introduction

• Background
• Building Information Models (BIM) and 4D models are

increasingly used for data sharing and communication purposes in real estate and construction sector

• Augmented Reality (AR), and more generally Mixed Reality

(MR), is enabling new kind of interaction with virtual building models at real environments

• Finland is one of the leading countries in BIM adoption, and

VTT leading research institute in BIM / AR development for construction industry

• Objectives
• To provide mobile AR (MR) tools linking real situation at

construction site to BIM information, planning and follow-up

• Combining top-level technology and know how from VTT’s

two knowledge centres and partner companies into novel world class solutions and products

Applications

• Augmented on-site visualisation
• linking project plans with actual situation on site
• determine already installed and missing parts, those to be installed next
• display part information, tolerances, weight, other measures
• display 2D drawings and plans, directions etc.
• display ready building before and during construction
• also, indoors applications for sales presentation
• Augmented site journaling
• feedback to system: sign (tag) installed parts in 4D model
• attach images to 4D model, with links to the parts they show
• construction log book, for communication between parties
• tool for building inspector during and after construction
• Office solutions
• augmenting virtual 4D scale models at meetings
• incl. virtual walk-though inside BIM model, using video glasses
• display construction order and schedule, with hyperlinks to real world imagery

Technology

• Augmenting / tracking
• vision based tracking matching with 4D model (orientation)
• combined with GPS and 2D map information (position)
• interaction to assist the system (increased accuracy)
• other tracking methods as required, e.g. for pre-construction visualisation
• Interaction with BIM models
• wireless 4D BIM model interaction methods, client / server solutions
• retrieval and feedback of model data, inclusion of image data
• based on e.g. Tekla software, integration with other tools
• Visualisation on mobile devices
• conversions from BIM to visualisation, e.g. OSG
• 3D graphics on mobile devices, e.g. visibility culling, LOD
• Hardware
• hand held / wearable PCs, miniature cameras
• optional data glasses (video or optical), accelerometer, compass
• wireless solutions, robustness, weight, power consumption, price
• with view on camera phones, client/server solutions

Benefits

• Lainauksia Pöyryn alustavasta ilmoittautumislomakkeesta:
• Pöyry-konsernin rakentamisen alueella toimivat yhtiöt odottavat AR4BC-

projektilta uusia hyödyllisiä innovaatioita rakentamisen elinkaaren koko suorittavalle alueelle.

• Tietomallin liittäminen, kaikkine jo nyt sisältävine mahdollisuuksineen,

ympäröivään todellisuuteen luo oikein toteutettuna mahdollisuuksia ja monia uusia lisäarvoja rakentamisen kaikissa vaiheissa ammattilaisten käsissä.

• Uusin tieteellinen Euroopan laajuinen tietämys viimeisimmästä

paikkahallintatekniikasta ja sen sovellutuksista (VTT), mallinnusohjelman syvä toiminnallinen tuntemus ja mahdollisuudet (Tekla), rakentamisen ammattilaisten tietämys (Skanska ja Pöyry) yhdistettynä jo aikaisempien projektien perustalle tuottanee tuloksia, joista rakentamisen eri osapuolet, tilaajat, rakennuttajat, arkkitehdit, suunnittelijat, urakoitsijat ja lopulta kiinteistöjen käyttäjät saavat uusia hienoja työkaluja arkipäivän rutiinien toteuttamiseen.
