Foreword
This code was prepared by the Technical Committee on Construction Industry IT Standard under the direction of the Information Technology Standards Committee.
This code was prepared with reference to some parts of, SS CP 6 : 1978 - 'Code of practice for building drawing'.
The use of computer-aided design (CAD) has been extensive and is still growing in the construction industry in Singapore. The ability of CAD to allow reuse and sharing of information will contribute greatly to the productivity in building design and construction, which involves extensive information and co-ordination between all parties in the building industry.
CAD files in the form of digital drawings are now a common medium of data exchange between all parties in building industry and the building authorities. The development of a set of CAD drafting conventions for use by all bodieslparties is a component in fully realising the potential of CAD for more efficient work and communication.
This code establishes a set of drafting conventions to be used by all parties in building industry who are involved in preparing and using technical documentation by means of CAD systems. It is envisaged that the set of drafting conventions in this code will be revised and updated regularly to adjust to changes in CAD technology.
This code has made reference to input from various standards organisations. Much of the information in this code has also been contributed by consulting firms, contractors and members of professional institutions. Acknowledgement is made to these firms that have given their permission to use the information in this code.
NOTE
1. Singapore Standards are subject to periodic review to keep abreast of technological changes and new technical developments. The revisions of Singapore Standard are announced through the issue of either amendment slips or revised editions.
2. Compliance with a Singapore Standard does not exempt users from legal obligations.
CP 83 : Part 4 : 2001
Code of practice for construction computer-aided design (CAD) Part 4 - CAD drafting conventions
1 Scope and objectives
The scope of this code is to recommend a set of drawing conventions to be used by all parties in the building industry in the preparation of drawings.
The objectives of this code are:
0 To provide a set of common drafting conventions for the building industry.
0 To facilitate a common understanding and interpretation of information in drawings by different users of the building industry.
To facilitate easy and efficient exchange of information.
2 Drafting conventions
Drafting conventions consist of hatch patterns, drawing sheet sizes, title blocks, abbreviations, etc. They are grouped under the following sub-headings and can be found in Annex A.
Sheet sizes and title block Plot scales Hatch patterns for material representation Line type representation Abbreviations - Architectural - Civil & Structural - Mechanical - Electrical - Miscellaneous - Units of measure
Drafting conventions in this code are those commonly used by the construction industry. In-house conventions can be used for more specific areas of works. However, these in-house conventions should be documented and communicated between different parties of a particular project.

Drafting conventions
A.l Sheet sizes and title block
Sheet sizes are based on the IS0 standards. The standard sizes are A0 to A4. The sizes are proportional, leading to simple reduction and enlargements. The bigger size sheets may be easily folded for filing and dispatch to that of A4 size.
The sizes of sheets in landscape format are as follows:

ABOUT THE 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 conformance, and small and medium-sized enterprises (SMEs) and the domestic sector.
Productivity and lnnovation
The Productivity and lnnovation focus has four key thrusts: promotion, business excellence, people excellence and service excellence.
Under its promotion thrust, SPRING Singapore spearheads the national Productivity and lnnovation Movement, The movement aims to cultivate strong commitment to productivity and innovation in all sectors of the economy and to develop a creative workforce and innovative enterprises. SPRING Singapore serves as Secretariat to the National lnnovation Council.
Using its internationally recognised Business Excellence programme, SPRING Singapore assists organisations to systematically achieve world-class standards of business excellence. At the apex of the programme is the Singapore Quality Award (SQA).
Under its People Excellence thrust, SPRING Singapore initiates leading-edge programmes to enhance the capabilities of the workforce. This enables them to scale new heights and achieve higher levels of productivity. SPRING Singapore administers the Skills Development Fund (SDF), which provides incentives to help companies defray the cost of training their employees. The incentives are financed through collections from the Skills Development Levy imposed on employers.
In view of the importance of service quality to competitiveness, SPRING Singapore spearheads Service Excellence in Singapore. The goal is to raise service quality levels in Singapore to world-class standards.
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.
As the national standards body, SPRING Singapore administers the Singapore standardisation programme, which involves the development and implementation of standards in industry. Please visit www.standards.orq.sq for more information. As standards and conformance issues can be potential barriers to trade, SPRING Singapore actively supports the government's Free Trade Agreement (FTA) strategy to ensure market access.
As the national authority for the accreditation of conformity assessment bodies, SPRING Singapore audits and accredits quality systems and the competence of quality system certifiers, inspection bodies, and testing and calibration laboratories.
SPRING Singapore enforces the Weights & Measures Act and Regulations to protect consumers by ensuring that market transactions based on weights and measures are accurate, fair and comply with the relevant standards.
As the Safety Authority, SPRING Singapore administers the Singapore Consumer Protection (Safety Requirements) Registration Scheme to ensure that the controlled goods used by consumers in Singapore are safe.
As Singapore's national metrology institute, SPRING Singapore ensures that the measurement infrastructure adequately supports the growing needs of industry. It maintains Singapore's national measurement standards for use by the industry, and provides the vital link between measurements carried out in Singapore and those in the international system.
CP 83 : Part 4 : 2001
SMEs & Domestic Sector
The SMEs and Domestic Sector area of focus has two thrusts: broad-based enterprise upgrading and industry transformation.
SPRING Singapore serves as the first point of contact for SMEs that need information and assistance for upgrading. As the lead agency spearheading the upgrading of SMEs, it adopts a total approach to developing SMEs into vibrant and resilient enterprises.
SPRING Singapore spearheads the transformation of the domestic sector. The goal is to create a vibrant, dynamic and resilient domestic sector that is able to contribute significantly to the overall economy.
SPRING Singapore administers two key financial incentive schemes for SMEs. The first is the Local Enterprise Finance Scheme (LEFS), which is a fixed interest rate loan for SMEs to expand and develop new capabilities. The second is the Local Enterprise Technical Assistance Scheme (LETAS), which is a consultancy grant scheme to help SMEs acquire new competencies in operational management.

ABOUT THE NATIONAL STANDARDISATION PROGRAMME
Under the national standardisation programme, SPRING Singapore helps companies and industry to meet international standards and conformity requirements by creating awareness of the importance of standardisation to enhance competitiveness and improve productivity, co-ordinating the development and use of Singapore Standards and setting up an information infrastructure to educate companies and industry on the latest developments.
SPRING Singapore is vested with the authority to appoint a Standards Council to advise on the preparation, publication and promulgation of Singapore Standards and Technical References and their implementation.
Singapore Standards are in the form of specifications for materials and products, codes of practice, methods of test, nomenclature, services, etc. The respective standards committee will draw up the standards before seeking final approval from the Standards Council. To ensure adequate representation of all viewpoints in the preparation of Singapore Standards, all committees appointed consist of representatives from various interest groups which include government agencies, professional bodies, tertiary institutions and consumer, trade and manufacturing organisations.
Technical References are transition documents developed to help meet urgent industry demand for specifications or requirements on a particular product, process or service in an area where there is an absence of reference standards. Unlike Singapore Standards, they are issued for comments over a period of two years before assessment on their suitability for approval as Singapore Standards. All comments are considered when a technical reference is reviewed at the end of two years to determine the feasibility of its transition to a Singapore Standard. Technical References can therefore become Singapore Standards after two years, continue as Technical References for further comments or be withdrawn.
In the international arena, SPRING Singapore represents Singapore in the lnternational Organisation of Standardisation (ISO), the International Electrotechnical Commission (IEC), the Asia-Pacific Economic Co- operation (APEC) Sub-committee for Standards and Conformance (SCSC) and in the ASEAN Consultative Committee for Standards and Quality (ACCSQ).
