Foreword

This Code of Practice was prepared by the Technical Committee on Construction Industry IT Standards under the direction of the Information Technology (IT) Standards Committee.

This code was prepared with reference to the following publications:

1. IS0 13567: 1998 Technical product documentation - Organisation and naming of layers for CAD, Part 1 : Overview and principles

2. IS0 13567: 1998 Technical product documentation - Organisation and naming of layers for CAD, Part 2 : Concepts, format and codes used in construction documentation

Acknowledgement is made for the use of information from the above references.

Current users of CP 83 include architects, professional engineers - C&S and M&E, as well as contractors who participate in Electronic Submission. The Urban Redevelopment Authority (URA) and the Building Construction Authority (BCA) have adopted the CAD layers for Electronic Development Application (EDA) and Electronic Submission System (eSS) respectively.

CAD vendors have developed software tools that can implement and support CP 83. BCA has been conducting hands-on training on CP 83 and the software application on various CAD platforms.

The revision of CP 83: Part 1 CAD layer names, is required in order to streamline industry practices for building projects as well as infrastructure projects such as the Mass Rapid Transport extensions which include architectural, civil and structural as well as mechanical and electrical works. The revised list of main and sub elements gives the users flexibility to combine the main and sub-elements based on their requirements.

The major changes are as follows:

Table 2 - Additional codes for originator field; Table 4 - Additional codes for first character of presentation field; Table 5 - Additional codes for second character of presentation field; Figure 2 - Examples of layer name structure - Mandatory and optional fields; Annex A - Revised list of main elements in alphabetical order; Annex B - Revised list of recommended sub-elements in alphabetical order; Annex C - Deletion of mapping of elements in CP 80.

Attention is drawn to the possibility that some of the elements of this Singapore Standard may be the subject of patent rights. SPRING Singapore shall not be held responsible for identifying any or all of such patent rights.

NOTE

1. Singapore Standards are subject to periodic review to keep abreast of technological changes and new technical developments. The changes in Singapore Standards are documented through the issue of either amendments or revisions.

2. Compliance with a Singapore Standard does not exempt users from legal obligations.

CP 83 : Part 1 : 2004

Code of practice for construction computer-aided design (CAD) Part 1 - Organisation and naming of CAD layers

1 Scope

This Singapore Standard establishes the general principles of layer structure within construction computer-aided design (CAD) files. It covers the organisation and allocation of layers that are used in CAD files for construction projects, and is intended to be used for communication and management purposes. A list of standard CAD layer element names is provided in this code.

The principles established in this code are applicable to all parties involved in preparing and using technical documentation on CAD systems. Although these principles are primarily for users, CAD system developers are expected to provide software tools capable of implementing and supporting this code. An important use is also to structure data in component libraries produced by third parties.

2 Purpose

The purpose of this code is to establish uniformity in the organisation and naming of CAD layers for the construction industry in Singapore.

3 Definitions

For the purposes of this code, the following definitions shall apply.

3.1 Layer

Organisational attribute of entities in CAD files, used to separate data in order to manage and communicate those data, to control visibility on the computer screen and on plotted drawings.

NOTE - In CAD systems, synonyms for "layer" are used, for example "level."

3.2 CAD model

Structured CAD data file(s) organised according to the physical parts of the objects represented, for example, a building or a mechanical device.

NOTE - Models can be two-dimensional or three-dimensional, and can include graphical as well as non- graphical data attached to the objects.

3.3 CAD drawing

Selected parts of a CAD model as presented on screen or on paper.

NOTE - Visibility on the drawing can be controlled by views and layers. The drawing can contain additional graphics, such as borderlines, title-block and legends. CAD drawings can also be produced independently without an underlying CAD model (a drawing-oriented approach as opposed to the model-oriented approach).

3.4 Plot

Graphic image created by a numerically controlled draughting machine and presented on draughting media.

CP 83 : Part 1 : 2004

3.5 Wildcard

A special character used to match any character or group of characters in a string comparison.

3.6 Layer name sub-classification

The following concepts are used in the layer name. An independent classification can be applied to each concept.

3.6.1 Originator

The originator refers to the individual/companylorganisation responsible for preparation and creation of information on the CAD layer.

3.6.2 Element

An element is a classified construction work or system. It consists of two levels of classifications, namely, main element and sub-element.

3.6.3 Main element

Main element is the first level of element classification. It represents the different types of main construction works or systems.

3.6.4 Sub-element

Sub-element is the second level of element classification. It represents the various sub-systems within the main element.

3.6.5 Presentation

Presentation is the format or type of information presented in CAD drawings. It is related primarily to the graphic appearance on screen and paper, as against element information, which is related to construction work or system.

3.6.6 Status

Status defines whether the element in addition-and-alteration works is new, for retention or demolition etc.

User-defined is an additional information field, which the user may wish to use for further subdivision of layers or provide a description not covered under this Singapore Standard.

4 Concepts, format and codes used in construction documentation

4.1 General

When CAD data is transferred between different systems and organisations, their structure needs to be understood for identification of the source of the CAD data, selection to suit the needs of different specialists and management of the data.

Layering is a commonly used technique to achieve such an organisation of CAD data. Layers are given unique names so that they can be selectively viewed and plotted. CAD layers need to be structured based on clear and logical organisation of information that fulfils the functional requirements of the information users. The organisation of these information can be achieved through the use of classifications of information in different parts of the layer name.

CP 83 : Part 1 : 2004

The following concepts, categories, format and codes shall be used to allocate layers on construction projects for the purposes of communication, management and submission to approving agencies. Those involved in any project shall agree on the selection of the layers and codes to be used and how the data will be transferred between their CAD systems.

All characters used in the layer names shall be both human- and machine-readable wherever possible. A layer format with fixed number of characters is used to allow selection of layers by the use of wildcard. Where reserved codes are given, they shall be used only for the purpose specified. Other project-specific codes may also be used.

Layer names are divided into fields. Each field holds one concept. Fields are either mandatory or optional. Mandatory fields shall always be included in the layer names. Optional fields can be used as required in each project. The order of fields in a layer name and the number of characters for each field shall be maintained as defined in this code unless an alternative is specifically agreed by the project partners. However, the alternative adopted shall be documented in a way that future retrieval of the layer-structured information can be ensured.

4.2 Format of layer name

A layer name consists of the following five fields as shown in Table 1.

Table 1 - Description of fields in a layer name

Name of field

4.3.3 For indication of no further subdivision of the information, hyphens shall be used to fill out to the end of the field.

4.3.4 Alphanumeric characters allowed are the letters A - Z, the digits 0 - 9, in addition to the hyphen and underscore characters.

4.3.5 All fields are left justified.

4.3.6 Unused trailing characters in a mandatory field shall be represented by the hyphen "-" character.

4.3.7 Unused trailing fields in optional part of the layer name can be omitted.

4.4 Layer name fields

4.4.1 Originator field

This field indicates the discipline of an individual/company/organisation responsible for the preparation and creation of information in the CAD layer. Since there is a multitude of possible classifications, depending on the type and organisation of the project at hand, two (2) alphanumeric characters are used for this field.

4.4.1 .I First character

This first character is a single alphabet code in capital letter to abbreviate the discipline of the originator of the layer. The list of possible originator codes is as shown in Table 2.

Other disciplines

CP 83 : Part 1 : 2004

4.4.1.2 Second character

The second character provides further definition of the originator whenever necessary. Example: AL to denote Landscape Architect. If the first character is sufficient to define the originator of the layer, a hyphen "-" shall be used as the second character of this field. Example: A- for architect and S- for structural engineer.

This second alphanumeric character can also be used to denote different originators from the same discipline involved in the same project. Example: A1 and A2 represent two different architects working on the same project.

4.4.2 Element field

This field indicates the type of construction work or system of the element in the layer. Classification for the construction elements or systems is in the form of eight (8) letters of the alphabet. This element field has two levels of classification, namely, the main and sub-elements.

4.4.2.1 Main element

The main element consists of four (4) letters of the alphabet and is mandatory. It identifies the main construction work or system of the element.

4.4.2.2 Sub-element

The sub-element consists of four (4) letters of the alphabet and is only used for further classification of the main element. For elements where classification using the main element is sufficient, the sub- element may be coded with four (4) hyphen characters "- - - -".

Table 3 shows some examples of classification in element field.

Table 3 - Examples of classification of element field

Standard main element names defined based on this classification are provided in the annexes of this code. Element names are arranged in alphabetical order in Annex A. To achieve consistency in the construction industry, users shall make use of the main element names provided in the annexes wherever applicable.

Recommended sub-element names are provided in Annex B. They are grouped under their respective main element. To achieve consistency in the construction industry, users should make use of the sub-element names provided in Annex B wherever applicable.

HANR - - - -

Users may generate element names that are not in the list of standard elements provided in the annexes of this code for their internal use. However, these user-defined layers shall be properly documented and communicated among the parties involved in the project. While there is no fixed rules in arriving at the 4-character abbreviation for the main and sub-elements, the general rule is to truncate the vowels and try to maintain the first and last characters.

4.4.3 Presentation field

The Presentation field represents the format or type of information presented and is denoted by one (1) or two (2) alphanumeric characters.

4.4.3.1 First character

There are two levels of classification in the first character field:

a) Basic classification

1) Element graphics;

2) Annotation;

3) Model (combination of element and annotation in model space);

4) PaperlPage (paper space or page information).

b) Further classification

1) Further classification of annotations: Text, hatching, dimension and marking;

2 Further classification of paperlpage: Border, tabular information, notes, legends, schedules, and diagrams.

The valid codes for the first character of the presentation field are given in Table 4.

STANDARDS, PRODUCTIVITY AND INNOVATION BOARD (SPRING SINGAPORE)

The mission of the Standards, Productivity and lnnovation Board, or SPRING Singapore in short, is to raise productivity so as to enhance Singapore's competitiveness and economic growth for a better quality of life for our people. In carrying out its mission, SPRING Singapore focuses on three areas: productivity and innovation, standards and quality, and small and medium-sized enterprises (SMEs) and the domestic sector.

Productivity and lnnovation

The Productivity and lnnovation focus has three key thrusts: promotion, organisational excellence and people excellence.

SPRING spearheads the Productivity Movement, which now encompasses innovation. A key strategy is the promotion of an innovation mindset among the workforce.

SPRING assists organisations to systematically achieve world-class standards of business excellence. At the apex of its internationally recognised Business Excellence programme is the Singapore Quality Award (SQA). Supporting programmes include those in the areas of innovation and service excellence.

SPRING initiates leading-edge programmes to enhance the capabilities of the workforce. This strategy supports the broader thrust of building up the competencies of organisations to achieve excellence.

Standards and Quality

The focus area of Standards and Quality has two major thrusts: standardisation and conformity assessment, and measurement infrastructure development. These are aimed at enhancing productivity, facilitating market access, ensuring safety and health, and protecting the environment.

SPRING administers the Singapore standardisation programme, which focuses on developing and promoting the use of standards in industry. It is also the national authority for the accreditation of conformity assessment bodies. SPRING enforces the Weights & Measures Act to protect consumers by ensuring that market transactions based on weights and measures are accurate. It also administers the Singapore Consumer Protection Registration Scheme to ensure that consumer electrical, electronic and gas appliances, and products are safe.

SPRING develops and maintains the measurement infrastructure to meet the measurement needs of industry. It provides a national system of traceability that covers measurements related to length, mass, time and frequency, electromagnetic, temperature, and radiometric and photometric quantities.

SMEs and Domestic Sector

The SMEs and Domestic Sector area of focus has three thrusts: broad-based assistance, enterprise upgrading and domestic sector development.

SPRING serves as the first stop for SMEs that need information and assistance for upgrading. As the secretariat to the Pro-Enterprise Panel, it actively seeks out suggestions on possible revisions to government rules and regulations to improve the business environment.

SPRING adopts a total approach in building up the capabilities of SMEs. This includes mentoring SMEs to map out strategic directions and implement best practices, and assisting fast-growing SMEs in areas such as business development and technology enhancement.
