B&V Steel Tools – Pre-CIS/2 – Problems

• Too many custom interfaces to maintain and coordinate

• Limited data throughput/scope (useful data lost or misinterpreted in transfers)

• Lack of flexibility to share data with client-selected tools

• PPADS (analysis/design engine) lacks updated AISC and international code design capability

• Inefficiency in using PPADS for design and GT STRUDL for dynamic analysis

Structural Tools Integration (STI)


STI Goals / Requirements

• Be a unifying solution that is standards-based (not proprietary)

• Support a broad scope of data to maximize data re-use and future growth in functional capability

• Enter once, then propagate data downstream for re-use in later process steps

• Provide opportunity to share data externally with B&V clients, vendors, and business partners

• Enable data exchange with tool capable of analysis and design to a variety of current codes

• Integrate with POWRTRAK® and POWRTRAK® applications, such as Plant Vision

STI Solution: CIS/2 Data ExchangeSTI Solution: CIS/2 Data Exchange

Adopt the CIS/2 standard for data exchange among B&V-used steel software tools.

Adopt the CIS/2 standard for data exchange among B&V-used steel software tools.


STI Solution – CIS/2 Data Exchange

• CIS/2 is the steel design and construction industry standard in North America.

• AISC formally endorsed CIS/2 in 1999.

• Many external software tools already support CIS/2, including those that B&V currently uses: GTStrudl, RISA-3D, Tekla Structures

• LPM/6, the CIS/2 data schema, can be implemented in the POWRTRAK® relational database.

• Plant Vision CIS/2 export prototype can be leveraged for production software.

Plant Vision-GTStrudl Geometry Exchange

• Plant Vision exports analysis geometry as CIS/2 (.stp) file– Includes geometry and loading– PV can create .gti files to direct GTStrudl analysis and design.

• GTStrudl imports CIS/2 file– ReadCIS2.exe translates .stp to .gti file

• GTStrudl user executes analysis & member design, as needed

• GTStrudl exports CIS/2 file– WriteCIS2.exe translates current model to .stp file

• Plant Vision imports analysis geometry from CIS/2 (.stp) file– Includes geometry only– Compares imported geometry with existing geometry, then inserts,

updates, and deletes steel members accordingly.

STI Design Process


STI Design Process

• Plant Vision acts as a GUI for steel data entry and review, space control, and information management

• GT Strudl selected as the preferred choice for analysis and design of large projects

• AutoCAD is used for creation of steel engineering drawings from the Plant Vision environment

• Tekla Structures is used for in-house detailing of steel and creation of erection drawings

• PPADS is used for some specialized functions• CIS/2 data transfer connects the programs and

allows flexibility where other software is required


• Plant Vision enhances steel layout by providing a user-friendly interface for steel modeling


• The model shows steel with accurate offsets and work points for space control…


• This allows engineers to check on access and headroom around equipment during steel layout…


• Keep steel clear of hoistways and pull spaces, review interferences…


• And check loading from attachments


• Other disciplines have access to live steel data to route utilities and tie-down equipment…


• Making Plant Vision the natural hub for our design process


• Users can distinguish analysis model steel from miscellaneous components…


• And filter or code steel by attributes such as floor level…


• The export template stylesheet automates GT STRUDL input file creation…


• Allowing new users to run a GTS analysis with minimal training…


• Streamlining model creation for large and complex structures…


• The analysis model combines features from Plant Vision, such as floor grouping and intelligent IDs


• GT STRUDL adds abilities missing in PPADS, such as nonlinear analysis and display of displacements


• Member design data is transferred back to Plant Vision, for use in steel detailing via Tekla Structures


• Using tools that can translate data from a single source improves quality and schedule

STI Innovations


STI Innovations – Database Repository (PMR)

• PMR = Product Model Repository [CIS/2 term]• CIS/2 schema (LPM/6) was mapped into a relational

database (POWRTRAK®)• Elements of the LPM/6 had correlating elements in

the POWRTRAK® database• POWRTRAK® is not a true CIS/2 PMR because it lacks

an interface allowing other applications direct access

STI Innovations – Plant Vision IDI Capability

• IDI = Incremental Data Import [CIS/2 term]

• During export, user locks subset of data that might be changed while in GTStrudl

• During import, Plant Vision reads imported file and compares to the existing Plant Vision CIS/2 model

• Only data locked during export is allowed to be changed by the imported data (from GTStrudl)


STI Innovations – XSLT Templates for .gti Files

• GTStrudl input (.gti) files are generated from an XML style sheet “template”

• The template transforms export-specific XML data from Plant Vision into GTStrudl input files customized for the exported model

• The .gti files are designed to encapsulate tasks in GTStrudl: Import, Analyze, Design

• Users may either use their own customized template to suit their project-specific needs, or select the “standard” template provided with the Plant Vision application

STI – CIS/2 Implementation Challenges

• In reality, external tools have varying degrees of adherence to CIS/2 standard:– Scope (Analysis, Design, Physical models)– Data Management Conformance (DMC)– Compliance (correctness)

• Plant Vision IDI capability must overcome current lack of DMC in interfacing applications

GTStrudl RISA-3D Tekla Structures Plant Vision

Scope Export: AnalysisImport: Analysis

Export: Analysis, DesignImport: Analysis, Design

Export: Analysis, PhysicalImport: Analysis

Correctness, Limitations

• Cardinal points artificially imported as element eccentricities, not maintained• Imported names limited to 8 characters

• Export element eccentricity and cardinal point are not independent•Element eccentricity is not relative to global coordinate system

•Import element eccentricity results in incorrect “handle” coordinates

• IDI uses name attribute rather than GUIDs for nodes and assemblies*

* Current Plant Vision production version; future versions will be enhanced.


STI – Value Statements

• Consistency - Focus on CIS/2 standard rather than specific proprietary functions of other tools

• Growth - CIS/2 provides a very rich scope of data, with “room to grow” – potential to increase data throughput and future exchange efficiency

• Data Management - PMR-based design foundation leverages POWRTRAK®, B&V’s existing engineering database

• Flexibility – B&V is more agile as future business needs may dictate using different CIS/2-compliant tools
