TCVN 5681 : 2012 replaces TCVN 5681 : 1992.

TCVN 5681 : 2012 was converted from TCVN 5681 : 1992 in accordance with clause 1 Article 69 of the Law on Standards and Technical Regulations and point b), clause 1, Article 6 of Decree 127/2007/ND-CP detailing the implementation of some articles of the Law on Standards and Technical Regulations.

TCVN 5681 : 2012 was compiled by the Institute of Architecture, Urban and Rural Planning, proposed by the Ministry of Construction, appraised by the Directorate for Standards, Metrology and Quality, and announced by the Ministry of Science and Technology.

1. Scope of application

1.1. This standard stipulates the content and method of establishing construction drawings for outdoor electrical lighting.

1.2. When preparing construction drawings for outdoor electrical lighting (hereinafter referred to as outdoor lighting construction drawings), it is necessary to comply with other relevant regulations.

2. Composition of construction drawings

2.1. Outdoor lighting construction drawings include electrical installation construction drawings (the main set of construction drawings) and non-standard structural drawings for installing lighting equipment and electrical equipment.

2.2. The composition of the main set of construction drawings includes:

– Title page;

– Outdoor lighting layout plan;

– Table of poles, towers with lights and lighting equipment, electrical equipment installed on them;

– Diagram of power supply and control for lighting (if remote control is required);

– Drawings of non-standard structures for installing lighting equipment and electrical equipment.

2.3. Outdoor lighting construction drawings are denoted by adding an Arabic numeral after the dot of the code of the main construction drawing.

For example: Title page drawing (general data) of the construction dossier (D-TC-1.1); Outdoor lighting layout plan (D-TC-1.2)…

2.4. On the drawings, use solid bold lines to represent details belonging to the electrical lighting system (power supply circuit, control circuit…), use thin solid lines to represent construction details and symbols for electrical equipment and lighting equipment.

2.5. The title page (general data), in addition to the requirements for construction drawings, must include the following contents:

– List of construction drawings of the main drawing set;

– List of summary tables (materials, light towers);

– List of reference and utilized documents;

– Symbols and conventional drawings;

– Other parameters (if any);

– General instructions.

2.5.1. The list of construction drawings of the main drawing set refers to Form No. 1 (Appendix A), in which:

+ The “Sheet” column records the number of the drawing sheet;

+ The “Name” column records the name of the drawing sheet written in the title block;

+ The “Note” column records necessary additional information about any changes that have been incorporated into the drawing.

2.5.2. The list of summary tables refers to Form No. 1 (Appendix A), in which:

+ The “Sheet” column records the number of the drawing sheet containing that list;

+ The “Name” column records the name of the list presented on the drawing;

+ The “Note” column records additional parameters.

2.5.3. The list of referenced and utilized documents refers to Form No. 2 (Appendix A). The list is divided into two parts: the referenced documents part and the utilized documents part.

In each part, the documents are recorded in the following order:

a) In the referenced documents part:

+ National standards;

+ Industry standards;

+ Typical equipment and component drawings.

b) In the utilized documents part:

+ Equipment and component drawings… that are reused;

+ Single-piece equipment and component drawings equipped for the project…;

+ Other documents.

In the list table:

+ The “Code” column records the document code, possibly including the name and number of the issuing agency;

+ The “Name” column records the document name according to the book title or the name written in the title block of the drawing;

+ The “Note” column records supplementary information including changes that have been incorporated when reusing the drawing.

2.5.4. In case the construction drawing uses symbols or conventional drawings that have not been standardized in relevant regulations, it is necessary to group those symbols into a section and provide specific annotations.

2.5.5. In the “General Instructions” section, do not repeat the requirements as well as technical solutions that have been recorded on the drawings, but must fully record the following items:

– Initial parameters for preparing construction drawings;

– Special technical conditions to note (ensuring noise reduction, corrosion resistance, relocation issues, work safety and operation…);

– Certifications of authorship rights for applied equipment or technology.

2.6. Outdoor lighting layout plan (OLLP):

2.6.1. The documents for preparing the outdoor lighting layout plan are the general layout construction drawings. The OLLP drawings are represented at scales of 1:100, 1:200, 1:500.

2.6.2. The outdoor lighting layout plan shows:

– Light poles with lights mounted on them and poles for installing overhead power lines;

– Lights installed on building structures or suspended on cables;

– Towers and poles for floodlights with floodlights installed on supporting towers and poles;

– Electrical technical equipment supplying power to outdoor lighting;

– Outdoor lighting system and outdoor lighting control system (when remote control is required);

– Connecting devices and other devices;

– Conduits for cables through walls, underground cables;

The drawing must fully show the positioning dimensions of electrical poles, light poles… relative to the benchmarks on the layout of the construction area (dimensions between them and dimensions to buildings…). Dimensions must be recorded in accordance with relevant regulations.

EXAMPLE: Representation of an outdoor lighting layout plan See Figure 1.

2.7. List of poles, floodlight towers with lighting equipment refers to Form No. 3 (Appendix A), in which:

– The “Position” column records the pole position according to the OLLP;

– The “Code” column records the code of the pole and tower according to regulations;

– The “Name” column records the name of the pole, tower and their type as well as the type of lighting equipment and electrical equipment;

– The “Quantity” column records the quantity of those items on the OLLP;

– The “Note” column records additional information related to the items listed in the table.

2.8. Diagram of power supply and control for outdoor lighting:

2.8.1. The diagrams of power supply and control for outdoor lighting include:

– Schematic diagram of power supply;

– Schematic diagram of remote control for outdoor lighting (if remote control is required);

– Installation diagram of equipment, distribution with voltages up to 1,000 V (when there is remote control).

2.8.2. The schematic diagram of power supply for outdoor lighting must clearly record:

– Protection and control devices related to lighting installed at power sources and in general distribution equipment with voltages up to 1,000 V;

– Outdoor lighting power supply grid;

– Letter and number symbols of power sources (when necessary), distribution equipment with voltages below 1,000 V, power grid lines…;

– Types of general distribution equipment;

– Rated current of protection and control devices;
