This looks like an Architects rending, but the view on the left is rending from a 3D model that we created for the entrance to the hospital on the right. We did this model for Turner to coordinate the structure with expensive Italian Marble cladding. The errors we found in the sub contractors approval drawing saved Turner time and money.

Design Stage – Alternate scenarios – 3D Graphical ModelFrom design stage to as built stage, some project participants are not yet prepared to deliver modeled environments. Successful results are dependent on the completeness of information included in the models. Elements not included in the modeled system leads to uncertainty and increased risk.This plant room from The Place at London Bridge was created from a dozen MEP plans and sections. Instant, real-time visualization via GoTo Meetings allowed the project team to resolve problems in minutes instead of weeks. The secant pile wall (red) was forced to relocate due to undocumented LUL assets under the site. Modeled plant room studies allowed the design team to quickly evaluate the extent of redesign required to accommodate the relocated secant pile wall.
Design Stage – Information Database3D visualisation is a single facet of useful information about the building. As the building design matures these 3D elements serve as a interface to dynamic information about the building systems that can be queried for size, materials, system, location and performance.
Design Stage and Construction Stage – WSP BIM ServicesConflict annotation is embedded in the master Federated model. PDF distribution of conflict reports allows for collaborative input from parties not currently immersed in the 3D environment.Conflicts and proposed resolutions are maintained in spreadsheet format to document responsible parties and track unresolved issues.
Construction Stage – 3D Graphical ModelThe PlaceThe building information model is a virtual model of the building’s architectural, structural and MEP systems, and includes a database of asset properties. The building model assists in clash detection, co-ordination, cost estimation and construction sequencing. BIM will be further developed throughout construction providing “as-built” information from the contractors. The model will ultimately serve as a tool for the client after construction, in operational mode for asset and facilities management.The Architectural and MEP models were created using AutoCAD Architecture and AutoCAD MEP. The structural model was created using Revit Structures. All models were imported into the composite, or federated, model using Navisworks Manage, through which clash detection was accomplished. Clash logs were maintained in Excel and clash reports were created using MS Word by importing images from Navisworks and clash log data from the Excel spread sheet. WSP also worked on transfer of structural steel model elements from the Revit structural design models to Tekla steel construction models to avoid replication of effort and maximize time available to solve problems.The model, was utilised for global collaboration, with the architect Renzo Piano Building Workshop based in Paris, Adamsons (the working architects) in Toronto and WSP in the USA and London, UK.
Facilities Management Stage – Information DatabaseThe WSP Group is leading a collaborative effort to establish a link between a platform neutral as-built model and a world class web based asset register.The above image includes a Tekla fabrication steel model, Revit concrete model and cadDUCT MEP fabrication model. Asset register by Zutec is populated online by the contractor and verified by the facilities management team on an ongoing basis as the building is constructed.MEP Services are modular elements produced off site to reduce waste and theft related to on site storage.
Design Stage and Construction Stage – WSP BIM ServicesEarly adaption of BIM protocols ensures successful integration of data from different software platforms. Even when working on a single platform, the BIM execution plan avoids confusion and avoids unnecessary efforts to align models or data formats.The BIM execution plan is a document meant to ensure that goals of a particular job are met. The plan must be tailored for each project to provide comprehensive but not excessive modeling work to meet the client’s needs.

MANAGING BIMThe quest to accumulate andintegrate building data in theUK Kamran Moazami WSP Group 21 October 2011
WHAT IS BIM?IT’S NOT A TECHNOLOGY, IT’S A PROCESSBIM: “A digital representation of physicaland functional characteristics of a facility . . .and a shared knowledge resource forinformation about a facility forming areliable basis for decisions during itslife-cycle; defined as existing fromearliest conception to demolition”.BIM is a socio-technical system which hasthe power to totally transform the designand construction industry and the way businessis done.
What is the main reason that UK demands BIM in all publicprocurement?• Construction cost over run and waste is a normal industry practice even with the introduction of CAD and automated design since 1980.• European Construction Industry 2003 reported £80bn waste.• The reported UK Government construction capital expenditure per annum is £60bn.• The Government also report a £10-20bn of waste due to: Incomplete design Inaccurate drawings, specification, production data Un coordinated drawings and data Ambiguous models or drawings
Government Expectation• Government expectation is for a roll-out of BIM, to at least level 2 by 2016, which includes the delivery of project and asset information within an integrated 3D model produced and managed through a collaborative process.• Not just buildings but infrastructure as well.
United KingdomDivided but not conquered BIM encounters scepticism in the UK The government is catching up Official standards released in 2009 Public procurement policy change in 2011 Doubts about the capabilities of software and motives of its vendors …BIM survey to over 6,500 construction industry professionals. …They showed a clear split in the industry. Almost half admitted they were not even aware of BIM; however, the remainder were aware and are making preparations to adopt it on the majority of their projects.” - Stephen Hamil, NBS BIM report 2011
What is the reason why the demand for BIM has not beenbefore?Perhaps• Economic boom • Industry too busy to realize the need.But also• Technology not there before. • Computers were not fast enough. • Computer software not as advance. • Data storage space not adequate • Lack of network communication speed.
