18.1 INTRODUCTION The University requires all of its consultants, suppliers and contractors to produce or procure drawn information to a common standard of presentation. Whilst it is appreciated that various standards are prevalent throughout the many professional practices employed in the construction industry, it is essential those firms employed by the University conform strictly to this Standard when working on University projects.

18.2 SCOPE OF THIS STANDARD This Standard applies to drawing production related to: a) Estate layouts. b) Estate Infrastructure. c) New and Existing buildings. d) Electrical and mechanical building services systems. e) Safety and Security Systems

18.3 COMPLIANCE WITH EXISTING STANDARDS Wherever possible this Standard relates to BS 1192-5:1998 for the structuring and presentation of drawings. The University has adopted the layering and segregation convention set out in Table 1 of the CI/SfB standard. The full CI/SfB classification of layering extends to several hundred sub-divisions but for practical purposes the layering has been condensed (See Appendix B)

18.4 CAD SOFTWARE The University has adopted AutoCAD Architectural Desktop as the preferred CAD system. If a firm does not use AutoCAD Architectural Desktop as their standard CAD programme, they must convert the drawings for the University to the AutoCAD format before any formal drawing issue. Issuing in DXF format is not acceptable due to potential file transfer problems, unless there are exceptional circumstances.

18.5 TITLE BLOCKS All Drawings shall contain a standard title block and border. The Title Block shall be inserted in the lower bottom right corner of the drawing. Client refers to the School or Division for which the project is being processed.


3 DESIGN GUIDE


18.6 NUMBERING Drawings must be numbered to the pre-defined system. Below is an example of the format with an explanation of what each character or character set refers.

Figure 3: Drawing Number Format (N.B. UEA Floor Levels beneath ground begin with 0 not - )

18.6.1 Explanation of Coding 006: Each Building or area of the Campus has a unique code number. See Appendix A for a full list of Building Codes. 02: Each Level throughout UEA Buildings has a Level reference. The External Walkway is generally Level 0. Roof level and roof plant rooms are treated as additional levels.

Figure 4: Level Numbering (General)

M: The Discipline code relates to the type of information shown on the drawing. See Figure 5 for explanation. The list is not exhaustive and advice should be sought from Estates

Management for the inclusion of other disciplines. 00253: The Project Number relates to the unique 5 digit project number assigned by the Estates Division. In the event that a project number is unknown advice shall be sought from Estates Management with company prefix U or E. 01: The Sequential drawing set identification number. The precise sequence is a matter for the individual Consultant. Numbers may be unique within the building, floor, or discipline sub groups of the project as required. A: The revision letter(s) can be any alphanumerical character annexed when an amended version of the drawing is issued.

Figure 5: Discipline Codes

18.7 LAYER IDENTIFICATION CONVENTION A typical layer reference is F220G, the layer name for Internal Wall Partition. Although layer names are not mandatory under BS 1192 or CI/SfB Standard, the University prefer layer names to be included. Viz. A-INTERNAL WALL PARTITION-G. The reason behind this convention is to assist operatives who are not familiar with the various standard classifications to be able to quickly find the information they require. This also correlates to the BS1192 Descriptive convention used by Architectural Desktop. Where layer names


5 DESIGN GUIDE


are used then the description must be base on the CI/SfB reference name. See Appendix B.

18.8 LAYER CONTENT Typically layering shall be such that all items can be easily identified and turned on/off, purged etc. Room numbers and/or room names are useful to other disciplines and should be capable of being retained visible once other text has been turned off. They should be stored in the space layout drawing.

18.8.1 Scale and Layouts Drawings shall be drawn at full size in model space at 1:1. When layouts are configured ready for plotting, the title block in paper space shall include the scale to which the Layout has been configured. If it is necessary for the same drawing to be plotted at different scales, a separate Layout should be configured, labelled and retained for each plot scale. Drawings issued to the University for comment, approval etc. shall be accompanied by a Plot Style file.

18.9 ROOM NUMBERING SYSTEMS 18.9.1 Rationale

The rationale of the numbering system is that every unique space within the University must have a unique identifier. To achieve this the system must be capable of identifying spaces based on the building, floor and room. The system is based on the assumption that every space that can be walked into must have a room number. Additionally every other space which occupies internal building area must have a unique identifier.

18.9.2 Ownership

To ensure data integrity and numbering consistency room numbers are owned by the Estates & Buildings Division. No school or division may change or update room numbering in an area without the express permission of the Estates & Buildings Division. Requests for a room number change should be made to the Estates & Buildings Division in writing or via email to [email protected] .

18.9.3 Room Numbering Format Building Number: 25/0.08 The unique building number must prefix every room number.


6 DESIGN GUIDE


Building numbers are issued by the Estates & Buildings Division IT/CAD Manager, a definitive list may be obtained from the Estates & Buildings Division web site or via email to [email protected] . Floor Number: 25/0.08 Each floor in a building has a floor reference. Floor 0 is generally the external walkway or for non-walkway attached buildings the entry level. Floors are numbered sequentially and are prefixed with a 0 see Fig 4. Room Number: 25/0.08 The room number is used to identify each unique space within a floor level. A space is numbered at floor slab level and is valid up to the ceiling of the space. Thus an atrium, void or multiple floor space would only be numbered at floor level. Various types of space use different numbering formats as defined below with the exception of some older residential buildings that are dealt with under Exceptions below.

18.9.4 Standard Rooms

Definition A room is defined as any space that can be walked into. Numbering Format Rooms are numbered numerically with an optional alpha suffix. Allocation Scheme Rooms should be numbered in a clockwise fashion beginning with the first room to the left of the main entrance to the building. Rooms only accessible via another room should use the main room number with an uppercase alpha suffix. Walk-in cupboards should use the main room number with an uppercase alpha suffix. Where rooms are divided additional numbers may be generated by adding an uppercase alpha suffix. Examples 1/0.01, 3/01.23A

18.9.5 Stairs

Definition Any feature that contains treads and risers from the base of the first riser to the top nosing, including intermediate landings, between floor levels.

Stairs are numbered sequentially and are prefixed with the ST mnemonic. Allocation Scheme Stairs should be numbered in a clockwise fashion beginning with the first stair to the left of the main entrance to the building. Numbers should be retained for a whole stair case. Example 25/0.ST01

18.9.6 Corridors

Definition Any space which is used as a dedicated access route, landing or fire escape route through an open plan area. Allocation Scheme Corridors should be numbered in a clockwise fashion beginning with the first corridor inside of the main entrance to the building. If possible corridors that represent landings at the top of stairs should use the same number as the stair, i.e landing at top of 100/0.ST01 should be numbered 100/1.CD01 Numbering Format Corridor numbers are prefixed with the CD mnemonic.

DESIGN GUIDE 8

18.9.7 Lift Shafts Definition Any space that is fitted with a device to enable people or goods to traverse floors without the use of stairs. Numbering Format Since lift shafts rarely start at or finish at a defined floor slab



level these are the only spaces which do not contain a floor level. Lift shaft numbers are prefixed with the LS mnemonic. Allocation Scheme Lift shafts should be numbered in a clockwise fashion beginning with the first lift shaft inside of the main entrance to the building. Example 3/LS01

18.9.8 Service Risers

Definition Any space which is used to enable services to traverse floor levels. Service risers may not be large enough to walk into but should still be numbered as discreet spaces. Numbering Format Service Riser numbers are prefixed with the RS mnemonic. Allocation Scheme Service Risers should be numbered in a clockwise fashion beginning with the first service riser inside of the main entrance to the building. Where possible consistent numbers should be used for a riser over its complete height, i.e. 3/0.RS01, 3/1.RS01 on each floor respectively. Example 3/0.RS01

18.10 LINE STYLE AND LINE COLOURS All lines shall be drawn in the default mode to the same thickness. Polylines shall not be used unless for presentation purposes or as closed polylines to denote useable space in space management drawings, building outlines, etc. The default line weight shall be:

A0 0.35 A1 0.35 A3 0.20

Line colour shall be set By Layer and the line style shall be selected by operator to suit the particular subject matter. Unless there are any special requirements, the line/layer colours shall be set in accordance with the plotting details shown in Figure 7.

18.11 SPACE LAYOUT STRUCTURING AND LAYERING Creation of space drawing: Space drawings consist of a closed Polyline to show net internal floor area of space i.e. room, corridor, riser, lift, plant room etc. The Polyline should be on layer F802G. The room numbers should be on layer F802T. For further details on layering, refer to layering convention for CAD (see Appendix B).
