Introduction

1 Introduction

This guide introduces the AVEVA Access platforms, Stairs and Ladders (ASL) application. It identifies the different types of user who would need to read this guide and sets out what knowledge they will need before they start. The section provides an overview of the main functionality that the application introduces.

1.1 Who Should Use this Guide?Administrators and discipline leads should use this guide to understand the concept of standards and be able to configure standards that define the engineering criteria that the Access platform, Stair and Ladder and assemblies will be evaluated against, the standards are fully configurable and can be applied to suit project requirements or international standards. This guide will also describe the Assembly World concepts that the Access platform, Stair and Ladder elements use.

Administrators should have a reasonable knowledge of PDMS database structures where they might need to configure rules and assembly geometry. A knowledge of PML is required if they need to set up PML expressions in the engineering criteria.

This guide does not cover product installation. Refer to References.

For details of non administrative process of ASL refer to the Access platform, Stairs and Ladders User Guide.

1.2 Product CompatibilityThe ASL application can be used with the following product:

• AVEVA PDMS DESIGN 12.0SP2.

There is no upgrade path capability of ASL model data based on pre 12.0SP2 versions of PDMS DESIGN to the 12.0SP2 ASL elements.

Overview of ASL Functionality

2 Overview of ASL Functionality

The ASL application is a PDMS DESIGN application for the DESIGN module that provides a bespoke database architecture of ASL elements comprising of the administrative elements below;

• Stair Tower (STRTWR)• Stair Flights (STRFLT)• Stair Landings (STRLNG)• Ladder (LADDER)• Platform (PLTFRM)• Handrail (HANDRA)

These elements are the high level administrative elements that are owned by the existing STRU hierarchy element, these elements with their easily identifiable element type definition supports the ‘Assembly’ type concept employed throughout the application where all of the detailed modelling is represented using the existing steelwork objects such as Gensec, Panel, Template and Fixing. For a detailed explanation of these elements, refer to the Structural Design User Guide. Throughout the application the workflow associated with the creation and modification of these elements follows a consistent format through a common user interface.

The ASL application builds on the existing database concepts and provides 3D model data in an integrated environment, enabling quick and easy browsing and reporting on that data.

Overview of ASL Functionality

2.1 Hierarchical Relationships of ASL AssembliesThe ASL elements of Stair Tower, Stair Flight, Ladder, Platform and Handrail are all POS/ORI elements whose hierarchical ownership is that of a STRU. The ASL elements should be considered as fabrications in their own right as they in turn own specific objects fulfilling an engineering function whose naming convention reflects the engineering function.

See the hierarchy view and descriptions below:

The descriptions and functions of these elements will be explained in the following sections.

These objects have been architected to suit specific functionality and workflow to provide definite engineering purpose and their attribute set accurately mirrors the engineering criteria for that object. The attributes are evaluated by the system in response to the user’s interaction with the 3D model environment and the relevant attributes are managed through the database hierarchy by the ASL application.

2.2 Simplified Parameterisation of ASL AssembliesProvides a simplified means to define parameters or rules (engineering criteria) for complex steelwork assemblies or fabrications and to de-couple the dependency on assembly geometry and parametric rules such that any ASL assembly can be managed by any particular standard responsible for validating and managing the engineering criteria.

2.3 System Evaluation of Engineering CriteriaThe basic workflow concepts along with the user and system responsibilities provided by the application are described and illustrated below;

2.3.1 Administrative Preconditions• The administrator has the necessary privileges to create or modify criteria or assembly

data and the criteria and assemblies have been defined in the APPLDW.• The assembly selection has been set up for the DESIGN user.

2.3.2 System/User Responsibility• The USER uses the application functionality to create, modify or delete assembly data

in the 3D model using the criteria and assemblies in the database.• The SYSTEM (ASL engine) analyses the positions and verifies the engineering criteria

of the assembly and then creates the instance in the database and maintains the assembly and its criteria until subsequent modifications are made to the assembly or data.

• The APPLICATION configures or sizes the parameters of the assembly to suit the USER input and sets any additional attributes such as references to standards and assemblies.

• The USER modifies the layout or any of the SYSTEM set criteria.• The SYSTEM re-evaluates the assembly as per the second step above.

2.4 Application Data Worlds (APPLDW)For more detailed information regarding Application Data Worlds sets refer to the Design Reference Manual Creating the Model.

Application Data Worlds and their elements assist applications to store assemblies and model parts for copying and propagation within a design. They have some similarities with Templates, but are more general in content.

They are used for ASL assembly data and also by the Piping discipline.

12.0 2:3

Page 12: Access Platforms Stairs and Ladders Administrator Guide

Access platforms, Stairs and Ladders Administrator Guide

Overview of ASL Functionality

The Elements available are administrative elements allowing applications to organise data storage areas of design objects that are not part of the design itself, but supplementary objects used to create and maintain the model. They will not be accessed (unless specifically instructed to do so) when performing model queries such as clashing, mass properties, collections and they are similar to catalogue and in particular Template definitions.

2.4.1 Application Data and TemplatesTemplates (TMPLates) can be included in the Application Data World, but only as instanced templates, NOT template definitions. Such templates can be refreshed from their definitions using existing (appware and core) driven functions. However there is no core supported means to refresh copies of Application Data in the real model.

2.4.2 Extension to Design DataDDAT elements have a new attribute PTOLER supplying a tolerance value as an alternative to, or instead of the MAXMIN values which determine the range of valid values when set. Applications using the Application data will use this value to validate its data.

2.4.3 Valid Value Elements (VVALUE) Additional AttributeVVALUE, owned by a DDAT can have a Valid Rule set stored in the attribute VALRULE. VALRULE is an expression attribute that can store an expression that evaluates to a logical true or false value. If the expression does not evaluate to a logical result, or if there are errors in the evaluation of the expression then the VALRULE will return FALSE when queried. The VVALUE element owns a Valid Value attribute (VALIDV) that is an expression returning a real, logical, text or reference value which supports the owning DDAT element. If the VALRULE is true or if it is a null expression then this VALIDV will be available to the DDAT.

VALRULEs are used by the system to control the choice of a Valid Value when property queries are made on the owning DDAT.

One example of a particular scenario shown below of a DDAT element owning four VVALUE elements with VALIDV and VALRULEs to control the size of a stiffener which changes in size due to the length of the stiffener:

The current set of VALIDValues available for the owning DDAT are the set whose VALRULes either are unset, or evaluate to TRUE. Those that are not available are those whose VALRULes either evaluate to FALSE, or whose evaluations generate errors.

VValue VVal expression VALRULE expression

VVALUE 1 ( ID /ANG35x35x15 ) ( LDPR LENG le 1800 )

VVALUE 2 ( ID /ANG40x40x15 ) ( LDPR LENG gt 1800 and LDPR LENG le 2400 )

VVALUE 3 ( ID /ANG45x45x18 ) ( LDPR LENG gt 2400 and LDPR LENG le 3000 )

VVALUE 4 ( ID /ANG50x50x18 ) ( LDPR LENG gt 3000 )

2.5 General Routing Path (RPATH)The RPATH element provides a multi disciplinary routing concept that provides common basis for defining any open path or closed boundary based objects in the 3D environment such as those used in the Platform and Handrail elements.

The primary objective is to provide consistent database schema with predictable behaviour in the creation of a path or boundary with a robust data consistency and internal checking mechanism that can persist data during the modification of the path or boundary once it has been created.

2.6 General Route Path ElementInformation specific to the core capabilities of the Routing Path element is available in the Software Customisation Reference Manual.

Getting Started

3 Getting Started

This section describes the application pre-requisites and the administrator responsibilities to provide the DESIGN user with the necessary data to create assemblies in the 3D model.

To access ASL functionality, launch the DESIGN module and select Design>Structures>Access, Stairs & Ladders.

3.1 Administrator Tasks

3.1.1 Administrator Access PermissionsIn order to create and modify ASL standards the Administrator needs the appropriate access permissions to the database and the Assembly Data World (APPLDW) data.

Administrator read/write access to the sample criteria and assembly data requires the ‘SYSTEM’ user to be a team member of the /ASLADMIN team and it is this team who own the /ASLCONFIG database. The sample criteria and assembly data provided with this release in the ASL APPLDW are created in the ASLCONFIG database.

The ASLCONFIG database should be included in all MDB’s where the administrator will be creating and modifying standards and the user will be creating ASL assemblies

Getting Started

3.1.2 Storage AreasBefore any new Standards, secondary standards or assembly geometry can be created a storage area should be assigned, the system will present a warning message if the administrator attempts to create a new standard with having previously set the storage area. To manage the setting of the storage areas, select Settings > ASL Storage Area from the menu toolbar to display the ASL –Default Storage Area form.

This form is sensitive to the access permissions of the user, if the user is an administrator the form displays with the area for Standards on the form being visible.

The general user however will not see the setting for Standards as it is an administrators responsibility

3.1.3 Creating Standards (Engineering Criteria)The Standards for Access, Stairs and Ladder application form provides the ability to create, copy, modify and delete the data. The tasks indicated on the form to Create, Delete and Copy are sensitive to the user permissions, where access is valid the task based links are active and where the permissions are invalid the task link will be inactive.

The application will be provided with a sample set of data based on a British Standard which is the default sample standard for this release. The application will allow the user to create their own default, user or project standards using the copy and rename functionality on an existing standard and simply modifying existing the attribute values (Valid value, Max/Min, Tolerance, Optimum or a PML expression), see below.

The Standards are managed by selecting Settings > ASL Standards and the criteria shown in the form is visible to the general user but not writable to the general user.

Access platforms, Stairs and Ladders Administrator Guide

Getting Started

The basic workflow for Creating, Copying or Deleting Standards is managed by this form and the activities are separated into three tasks;

• Standards• Secondary Standards• Properties

3.1.4 Standards

Create a New Standard

Creating a new ASL standard will display a form requesting both the Name and Description of the Standard which updates the Design Explorer with a new Application Data Area (APPDAR). There is no limit to the number of APPDAR that an APPLDW can own so the user the flexibility to create any number of Standards.

Delete the Selected Standard

Deleting the Standard will delete the engineering criteria associated with the assembly data and where the assembly data has been instanced in the 3D model the rule checking engine and the ability to intelligently update the ASL assembly will be lost. The instances of the ASL

assemblies all store and use references against the standard (ASLStandard), secondary standard (ASLSbStandard) and assembly reference (AssTmpReference) with which they are defined so deleting the standards or assemblies will delete these references.

Copy the Selected Standard

Copying existing standards provides a quick and efficient method of creating new standards and simply editing the properties in the form control grid.

3.1.5 Secondary Standards

Create a New Secondary Standard

Having created an ASL Standard (and a corresponding APPDAR) for the encapsulation of the criteria the Standard can then be sub-divided or categorised into secondary standards, in this instance the secondary standards capture the different criteria of ‘Public’, Semi-Public’ and ‘Private’ secondary standards. For example, in the case of a Ladder conforming to a ‘Public’ secondary standard it would have rigidly defined degrees of freedom in its allowable tolerances than those specified for a ladder conforming to a ‘Private’ secondary standard where its criteria are much more generalised.

In database hierarchy terms the Secondary standard is managed by the Application Data (APPLDA) element.

Delete the Selected Secondary Standard

As with the deletion of the standard, deletion of the secondary standard should only be undertaken with care as there are instances of the standard and associated geometry in the 2D or 3D environments which will loose their references.

Copy the Selected Secondary Standard

Copying existing secondary standard provides a quick and efficient method of creating new sub standards and changing the attribute settings for subsequent use.

3.1.6 PropertiesHaving created the standard and secondary standard; the properties need to be created or modified depending on the method of creating the Standard/Secondary standard. The properties manage the engineering criteria against the appropriate attribute for the relevant ASL object. The engineering criteria of the ASL objects such as STRFLT, Ladder are defined and managed by the Design Data Set (DDSE) which is owned by the APPLDA. The DDSE corresponds to an ASL element type which has a separate Tab for managing the values against the attribute property (Description field).

Getting Started

The Description field is a listing of the attributes against the STRFLT element. The DDAT stores the engineering criteria in the form of an expression, Real, Max/min or VVAL, it is this data in the DDAT elements that effectively parameterises the assembly and what the rule checking engine performs its analyses against. Indicated below are the expressions the 'Relationship between rise and going' DDAT element stores;

3.1.7 Creating ASL AssembliesThe ASL assemblies should be created in the appropriate Application Data World hierarchy of the database as this means that they will not be clashed or queried by the system, unless they have been instanced in the 3D model.

The creation of assemblies will require some knowledge of the Steelwork application and its existing GENSEC and PANEL elements used for the detail representation of steelwork together with an understanding of PML syntax. To allow the creation of more complex assemblies an understanding of the rule syntax would be an advantage where the rules referred to are identical to the rules and expressions used to create Template elements.

3.1.8 Creating ASL SelectionsThe Selections for Access, Stairs and Ladder application form is used to expose the relevant assemblies to the project, this functionality allows the Standard (Assigned Standard) and the Assemblies (Assigned elements) to be used in combination and manages the presentation of this data in the general users application such that the user can decide which standard and assembly to use. The form also allows new selections to be created, modified or deleted. It is then the responsibility of the system to manage the checking of the engineering criteria based on the graphical picks or selections or manual inputs from the user.

The figure above left shows how the Selections form manages the visibility of the Assembly elements and provides the functionality for the administrator to promote the Stair Flights and other ASL assemblies, to the Assigned elements grid. The elements visible in the lower potion of the form under the heading Assembly elements are not visible to the ASL Design application and hence the user. This form allows the administrator to assign only those assemblies that have been authorised for use on the project.

Getting Started

The Db structure on the Application Data World indicated above right shows the database explorer and the location and hierarchy associated with the Standards, Secondary standards and the Assembly data. Notice that both the standards information and the assembly data are located in adjacent APPDAR under the same APPLDW.

Create a New Setting

Creating a new ASL setting will display a form requesting both the Description of the setting and the Setting Type which updates the main menu toolbar to inform the user of the current selection available to use.

The application allows for both Project and User selection settings to be created and the Description gadget is autonamed based on the Setting type which can be either Project or User and the autoname is not a hard-coded naming convention so the administrator can edit the name to a more appropriate name.

The User and Project Selections are saved to the following directory and files;

The user settings are stored in the PDMSUSER directory and the Project settings are stored in the Project Default path directory, for example; SAMDFLT folder, BASDFLT folder.

Delete the Selected Setting

The user will be prompted to confirm the deletion of the selected setting which will update the main menu toolbar.

4.2 Description of Stair Tower ElementsThe elements denoted with the (…) after the element type identification are described in more detail under the appropriate section heading.

4.2.1 Stair Landing (STRLNG)STRLNG is owned by the STRTWR and acts as a transition between the multiple Stair Flights also owned by the STRTWR, the boundary of the Stair Landing element is defined by the application using the appropriate template within the APPLDW and the upping coordinate is typically coincident with the Lower and Upper Work Points of the Stair Flight elements which are defined by the user. The physical representation of the Stair Landing element is defined using the existing GENSEC and PANEL element.

4.2.2 Tower Steel (TWRSTL)TWRSTL is used by the STRTWR to manage the layout of the Steel structure of Beams and Columns supporting the Stair Flight and Stair Landing layout. The primary function of the Tower Steel is to manage in an intelligent manner the relationships between the Top of Steel (TOS) elevations of the supporting beams and the associated Finished Floor Levels (FFL) for Stair Flights or Ladders accessing the Stair Tower.

4.2.3 Access Set (ACCSET)Access locations in the Stair Tower are defined and managed by the application, the ACCSET can own any number of Access Points. Access Points are elements that imply a logical connectivity or reference concept in that they represent the link between the two locations being accessed from and to. The attributes of the Access Point define amongst other things the position, orientation, size (clear opening) and also includes an 'Access reference' for referencing adjacent locations.

Stair Flight (STRFLT) Assembly

5.2 Description of Stair Flight ElementsThe following figure shows some of the attributes of the STRFLT and its offspring and the engineering significance of those attributes to the geometrical representation of the STRFLT.

Upon creation of the Stair Flight the system will analyse the horizontal (Overall Going) and vertical (Overall Rise) distances between the Lower and Upper Work Points (LWP/UWP) and validate these positions against the engineering criteria of the Stair Flight to the criteria of the current specification. If the system analysis validates the values against the engineering criteria the system will create the Stair Flight and populate the attributes with the appropriate data.

6.2.5 Cage Segment (CAGSEG)CAGSEG owns the GENSEC and PANEL steelwork elements used to model the physical representation of the Cage. By default their will be two Cage Segments, one representing the Entry/Exit at the top of the Ladder and the other representing the remainder of the Cage itself, this mechanism allows the Entry/Exit detailing of the Cage to be modified individually from the remained of the Cage though other modification tasks do act the whole cage. If subsequent updates to the adjacent model require that new Entry/Exit locations are required the user can create additional Ladder Exit elements to suit and the system will create additional Cage Segment elements as appropriate. The Cage Segment also supports an implied connectivity mechanism using reference attributes to Ladder Exit elements.

6.2.6 Ladder Exit (LDREXT)LDREXT has no physical offspring but in combination with the CAGSEG provides an implied logical connectivity or reference concept that manages the link between the LDREXT and the CAGSEG.
