Part 1

0.1 Overview

Estates Services is responsible for the refurbishment, repair and maintenance of the entire building stock of the University. Much of the building information is in the form of drawings, which are stored in three forms:

Electronic format, using AutoCAD drafting software. Electronic format, as scanned images on a database (TIF). Sketches and received drawings in paper format.

All project related drawings that are produced within, or for, the UWE Estates are to be produced digitally utilising `dwg format for storage of files.

The current in-house CAD system for producing drawings is based upon AutoCAD drafting software. In order to manage the CAD system effectively it is necessary to follow a definitive convention for undertaking the various activities involved in producing drawings to ensure conformity and understanding of drawings.

This procedure lays out the requirements for producing standard CAD drawings by all Consultants or Contractors working on projects for the University of the West of England.

0.2 Paper, film etc drawings

With the exception of sketches or minor details, which do not need to be permanently stored, drawings are no longer produced in this form.

Any further hard or paper drawing information received is most likely to be as part of Operation and Maintenance Manuals (O&M), and will also be in electronic format.

0.3 Electronic Format Drawings 0.3.1 Storage

All University Buildings are assigned a unique building short code. This code is incorporated in all project names, project drawings and master drawings.

(See Appendix 1)

All electronic drawings are to be stored on the departmental drive: S:\Facilities\Estates\Drawings..

0.3.2 UWE Master Drawings

A set of Master Drawings is being compiled for every building, which will comprise of a floor plan layout for each level of the building showing ceilings, furniture, audio visual equipment. Services drawings (mechanical, electrical, fire etc.) use these floor plans.

The Master Drawings are stored in:

S:\Facilities\Estates\Drawings\MASTER DRAWINGS

0.3.3 UWE Project Drawings

UWE construction projects are located electronically under:

S:\Facilities\Estates\Projects\01 Construction\.......

SharePoint: AutoCAD drawings have to be saved on the S drive, as above. Issued drawings as PDFs are on the relevant SharePoint site. The UWE Estates webpages contain a comprehensive list of all Facilities Estates projects being managed on SharePoint. Authority for access is granted by the Project Manager or the Project Support Team. Please refer to the webpages or use the following hyperlink: https://share.uwe.ac.uk/sites/proj/facprog/Lists/Project%20List/AllItems.aspx?PageView=Shared.

File structure for project drawings is as follows:

0.3.4 Drawing Creation

If Master Drawings exist, then these shall be used as the basis to create project drawings. Should no Master Drawings exist, then the Record project drawings will become the Master Drawings.

0.3.5 During the Project

Project drawings will not change the Master Drawings during the progress of a project. This is because of the possibility of a project being cancelled, changed or postponed either prior to or during the construction phase.

0.3.6 At Project Completion

Following the successful completion of the project, Record information shall be obtained from the Architect, Consultant or Contractor.

This shall be used to modify the project drawings. On smaller projects, this shall generally be done in-house. On larger projects, this shall generally be done by the Architect or Contractor.

0.3.7 Conversion to Master Drawings

Once the Record information has been received, the Master Building Drawing and Master Services Drawing(s) will be updated.

All original incoming, Consultants or Contractors Cad files are to be placed into the dedicated pending folder within the relevant site directory in the Drawing Masters. They are then checked that they conform to the UWE CAD standards, i.e. layers, colours, line-types, etc and then updated to the Master Drawings

0.3.8 Drawing Register

The Master Drawing Register is an Excel document, with hypertext links, (updated as new drawings are created) and is located in:

S:\Facilities\Estates\Drawings\DRAWING REGISTERS

0.3.9 Superseded / Previous Revisions

Previous revisions of Project Drawings shall be moved to a superseded folder i.e.

Project File\Superseded\

0.3.10 Closing / Saving Drawings

When drawing files are to be closed, they must be saved to the default status, as follows:

All required layers are turned on Zoomed to extent Paper space view

0.4 UWE Cad File Reference and Drawing Number Naming Convention 0.4.1 Master Drawings

The cad file reference system for Master Drawings will adopt the following convention:

Field No. 1 - Campus

The first two\three characters identify the site location and building (see Appendix 1 for coding)

Field No. 2 - Building/Block/Court

The next four characters represent the commonly used building short code as used within the Space Management Systems (see Appendix 1 for coding).

Field No. 3 - Level

The next two characters identify the floor level (It should be noted that floor levels are based upon the datum level not the storey location) e.g. L1 = Level 1

Field No. 4 - Discipline

The next character identifies the discipline of drawing, e.g. B=Building, M=Mechanical, E=Electrical, A=Asbestos, F=Fire.

Field No. 5 - MASTER

The Master cad file name is defined by the suffix MASTER, e.g. PLAN MASTER, LIGHTING MASTER, HEATING MASTER.

A suitable name is to be given to other disciplines, e.g. SECTION, ELEVATION, DETAIL, SCHEDULE, SCHEMATIC, PLANT ROOM.

Some of these will be used simply for information and will not be updated, others e.g. Schematics will become Master Schematics and will be updated.

Drawing Number

For Master Drawings, numbers are not applicable. The word MASTER is entered into the Drawing Number section of the title panel.

Revision

Master Drawings are to be revised when updated, by recording the detail of the amendment in the revision box and the Revision Letter updated in the format of A1, B1, C1 etc to allow for multiple revisions. The cad file name will remain unchanged.

0.4.2 UWE Project/Other Drawings

The Project cad file reference system for Project/Other Drawings will adopt the same convention, but without the suffix MASTER, e.g. Plan, Detail, Lighting, Heating etc.

Drawing Number

All Project Drawing numbers are to be sequential e.g. Building B01, B02, B03, Mechanical M01, M02, M03, Electrical E01, E02, E03 etc.

This number to be entered into the Drawing Number section of the title panel and quoted, along with the project Reference in any technical specifications and issue sheets.

0.5 Drawing Issue

Drawings issued at various stages in a project are to be clearly identified in the drawing to show its status. This should be done by entering it in the Status Panel on the drawing and by using the correct revision. The main stages are:

PRELIMINARY ISSUE P1, P2, P3 etc TENDER ISSUE T1, T2, T3 etc CONSTRUCTION ISSUE C1, C2, C3 etc RECORD ISSUE RD

0.6 Issue Sheet

All project drawings to be issued with accompanying UWE Drawing Issue Sheet (See Appendix 4).

0.7 Sending and receiving Drawings

Drawings are to be sent in pdf format as standard with dwgs available on request.

0.8 CAD Production Details

The full details of how CAD drawings are to be produced are laid down in Appendix 2.

0.9 B.I.M.

UWE recognises the requirement to achieve B.I.M. Stage 2 by 2016 and is actively working towards this. This will include 3D modelling for all major new builds. See separate Appendix for details.

APPENDIX 2 - Detailed CAD Drawing Production Standard



DETAILED CAD DRAWING PRODUCTION STANDARD

2.1 AutoCAD Templates

These can be found in: S:\Facilities\Estates\Drawings\CAD STANDARDS\Drawing Sheets\UWE Drawing Sheets.dwt

2.2 Setting Up A New Project

New projects should be set up before any drawing work is undertaken. Only the Project Surveyor / Project Engineer, in conjunction with the administrator, should carry out the set up. The following stages are fundamental to ensure the smooth operation and management of the project.

Create new Job No. folder on the Server. Create all Sub-folders re standard project set-up.

2.3 Drawing Naming Convention

Refer to Section 0.4.

2.4 CAD File extension definitions

The following terms are used by Autodesk and UWE to define formats of CAD files used:

.DWG file An AutoCAD drawing file

.DXF file An AutoCAD Digital Exchange Format file. Generally used for translating files between AutoCAD and other CAD systems

.DWT file An AutoCAD template file used to create a new drawing

.BAK file An AutoCAD backup file

.DWF file Drawing Web Format for viewing AutoCAD drawings in programmes other than AutoCAD

.CTB file Named plot styles table pen assignments for all drawings and associated plotter pens (colour, linetype, lineweights, plot styles)

2.5 General

2.5.1 All drawings will be produced using the current version of AutoCAD that is in use at Estates Services (currently Autocad 2013), but to enable easier sharing between parties, the default save setting for all drawings should be set in Autocad settings to save back to the last save setting (currently Autocad10).

2.5.2 All drawings will be set up with the UWE Drawing Sheets in paper space using the UWE Drawing Sheet template (see 2.1 for location).

2.5.3 UWE drawing sheets can be brought in by selecting Template from the Layout command in Autocad, and by using the UWE Drawing Sheets.dwt template. This contains landscape and portrait sheets from A0 to A4. Attributes have been set up within the title block so that information can be entered. This includes the Campus, the Project Name, the Project Reference, and the Cad file reference so that drawings can be located easily. See example.

2.5.4 The UWE drawing sheets contain various standard layers, text styles, dimension styles, and line-types. They also bring in the CTB plot style tables (Named Plot Style Tables).



2.5.5 Unless unavoidable, all project drawings (all disciplines) should use drawing sheets of the same size, orientation & scale throughout the duration of the project. Discuss with other members of the design team before commencing initial drawings.

2.5.6 All drawings will be drawn full size (1:1 scale) in millimetres (model space); however highways, mappings and surveys often need to be full size (1:1 scale) in metres.

2.5.7 Where details are required on a drawing at various scales it must not be achieved by scaling in model space. The drawing of the detail should always be drawn at 1:1 in model space. Then in Paper Space a separate viewport needs to be created at the required scale.

2.5.8 To avoid problems with overlaying information, the drawing in model space should not be altered by either moving, changing the scale or rotating. The orientation should only be altered by changing the UCS. The World UCS is in line with North and a separate UCS called BUILDING has been created to align with the building. This is how the drawing will be saved.

2.5.9 When the drawing is completed, it should be purged to remove objects not used. This will help reduce the size of the drawing file.

2.5.10 Delete all unused layout tabs not required.

2.5.11 When exiting a drawing ensure that all required layers are turned on and ready for plotting with the full paper space view displayed on the screen. This not only enables the viewer to see the drawing on the preview but also assists with batch plotting. It is also good practice to make full use of layer manager whenever possible.

2.5.12 All drawings shall be stored in the correct sub-folder underneath the appropriate Building sub-folder (Refer to 0.3.Project Files).

2.5.13 Building plans have been positioned relative to the site plan so that full site drawings can be produced.

2.5.14 Project drawing files will contain the services information within model space on the appropriate layer. The building outline information will be attached as an external reference.



2.6 External Reference Files (Xrefs)

2.6.1 The appropriate master drawing should be used for all project drawings.

2.6.2 The correct use and control of building outlines via Xrefs makes it easier to maintain and control changes. Xrefs should be used by all disciplines throughout all projects.

2.6.3 Only one master drawing (the current revision) for each floor plan/detail/ section is to be kept in the MASTER DRAWINGS sub-folders at any one time.

2.6.4 Caution should be used in the update & modification of Xrefs and other reference files in that a change by one person will affect all drawings in all disciplines, using these files.

2.6.5 All Xrefs should generally be attached using the overlay method. This avoids Xrefs being passed from sub drawing files. Attach should only be used when the Xref is required to be passed onto another drawing.

2.6.6 Xrefs should be inserted onto a layer called Z_Xref, which should then be locked. Individual layers for the Xrefs can then be switched on or off as required.

2.6.7 This not only speeds up numerous drawing amendment processes, but allows improved control over display order when using grey/ shaded layers/items.

2.6.8 Xrefs should generally be inserted at the co-ordinates 0,0,0 with the UCS set to World and the rotation angle to 0. Ensure UCS icon is always switched on.

2.6.9 Data should not be relocated away from the original survey grid, as sometimes it is a requirement that all drawing files are to be positioned in the correct location over the OS Map. The setting out position should remain constant throughout the project. If the architect/contractor moves his/her details from their original insertion/origin point, then these details should be corrected during production of revised Xrefs. UWE layouts should not be amended to suit these changes in location. Instead the architects/contractors plan is moved back into its previous location, as initial issue.

2.6.10 Individual layers within an Xref may be switched on or off as required. System variable VISRETAIN controls whether changes made to external reference layers are retained when an Xref is reloaded or a drawing re-opened. This is also a setting in Options command under the Open/Save tab and should be ticked to retain changes.(N.B. Visretain=1 retains changes and Visretain=0 discards changes).

2.6.11 When emailing drawings with xrefs, the AutoCAD command Etransmit should be used to create a single file containing all the files relevant to that drawing.

2.6.12 If a new architects file contains several sections or elevations these should be broken down into separate Xref files.



2.7 Drawing Units and Scales

All drawings shall be drawn in Model Space at a scale of 1:1 where one drawing unit = 1mm. Angles shall be shown in decimal degrees and measured anti-clockwise with 0 measured as a horizontal line drawn to the right. The preferred scales for use are 1:1, 1:2, 1:5, 1:10, 1:20, 1:50, 1:100, 1:200, 1:250, 1:500, 1:1000, 1:1250 and 1:2500.

2.8 Text

2.8.1 Guidelines have been set up to determine the standard style and size of text used on UWE drawings to ensure uniformity throughout all drawings. Text styles used on drawings are inserted with UWE Drawing Sheets.dwt template file and are set up with a height of 0 (which allows the user to add the required size) and with a width factor of 0.8.

All general text shall be as a minimum, 2.0mm high x the scale of the drawing, Uppercase in Mtext and with 0.8 Width Factor.

Room details e.g. name and area should use the style UWE_Arial which is font Arial.

All text for titles, headings, etc shall be as a minimum, 3.0mm high, with 0.9 Width Factor.

The user can choose from UWE_ARIAL, UWE_SWISS721, UWE_CENTURY GOTHIC or UWE_CITYBLUEPRINT.

For example, a drawing drawn at 1:100 would have a text height (in Model Space) of 200mm, and the height of the text in Paper Space would be 2.0mm.

2.8.2 Non-standard AutoCAD fonts should be avoided as this can create problems when exporting files to other consultants.

2.8.3 All text except units of measurement (eg mm) should be written in upper case.

2.8.4 With the exception of survey drawings, all text should be entered at a rotation angle of 0 except where text needs to be read vertically and the rotation angle should be 90.

2.8.5 The new text alignment facilities in MTEXT in AutoCAD should be used whenever possible.



2.9 Dimensions

2.9.1 The automatic dimensioning facility must be used for all dimensions. Do not explode dimensions into their constituent parts. Dimensions can be annotated, but should always be to scale.

2.9.2 Various Dimensioning Styles with different terminator styles will be brought in with the UWE template files. Below are a few examples:

UWE100 Arrow The terminator will be a Closed Arrow for a scale of 1:100

UWE100 Dot The terminator will be a Dot for a scale of 1:100

UWE100 Oblique The terminator will be an Architectural Tick for a scale of 1:100

2.9.3 Either Arrows or Ticks should be used depending on the type of drawing being produced.

2.10 Hatches

2.10.1 Only Standard AutoCAD hatch patterns should be used and they should be Associative.

2.10.2 Do not associate hatch patterns to entities that are part of a Xref.

2.10.3 The hatch pattern dots is memory hungry and should be avoided.

2.10.4 Do not explode hatches.

2.11 Symbols Library

2.11.1 Standard UWE Symbols and Blocks are available in:

S:\Facilities\Estates\Drawings\CAD\Blocks\ (Refer to Appendix 3)

2.11.2 All symbols are inserted onto an appropriate layer.

2.13 Line Types

Standard AutoCAD line types (acadiso.lin) must be used. Site survey drawings showing main service supply routes may use special line types such as:

GAS___GAS___GAS



CCTV___CCTV___CCTV

These special line types must be supplied with the drawing files.

2.14 Line Types and Line-type Scale

To ensure consistency between drawings, maintain presentation and keep all line types the same in all drawings, all users must keep to the line styles provided with AutoCAD. AutoCAD provides two linetype files: acadiso.lin (metric) and acad.lin (imperial). The acadiso.lin file is brought in with the UWE template file and this should be used for most lines. The acad.lin file should not be used (this is so that linetype scaling provides better control of the output file).

The linetype scale (LTSCALE) is a command which sets the size of each line style based upon the scale it is viewed at.

As a general rule, in model space the global LTSCALE should be set to 0.4 of the proposed drawing scale, hence a typical 1:50 drawing should have a global LTSCALE of 20. The variables PSLTSCALE and MSLTSCALE should always be set to 0 so that linetypes appear the same in model space and paper space.

When there are different viewports in a layout at various scales the global LTSCALE should be set to 0.4 of the drawing scale and the PSLTSCALE should be set to 1.

All objects in the drawings must keep their bylayer properties. Therefore if more than one linetype is required for a particular category, multiple layers for each can be created to suit.

Standard line-types used for Mechanical Services Layouts are:



PHANTOM = Pipework above ceiling CENTER = Pipework at high level CONTINUOUS = Pipework at low level HIDDEN = Pipework below floor



2.15 Layering Convention

2.15.1 A standard CAD layering system is necessary to enable consistent drawing production from a wide variety of sources and services. UWE Estates follow the BS1192 Descriptive Layering Standard, (with minor modifications to suit the use of the University).

2.15.2 Standard layers used by the UWE, Estates Services can be found in:

S:\Facilities\Estates\Drawings\CAD\Layering UWE Convention

2.15.3 Since the Layering Standard uses a Named Plot Style Table for the correct plotting of drawings in AutoCAD, the following must be strictly adhere to:

All objects should be colour bylayer Linetype set to bylayer Lineweight set to bylayer

2.17 Plotting Procedures

To ensure that all paper information produced from the UWE CAD system is of a consistent standard, all of the following procedures should be followed. The CAD Technician is responsible for carrying out all necessary checks before committing the CAD file to the plotter/printer.

2.17.1 Check the drawing content carefully to ensure that all of the changes have been carried out carefully.

2.17.2 All CAD data must be checked to ensure that all information corresponds to the CAD standards detailed in this manual:

All data has been produced using the appropriate layers.

Check that the correct colour, linetype, lineweight and plot style have been used to represent each object.

2.17.3 Make sure that the latest layouts are being used from other disciplines. If incoming procedures are correctly followed then this should always be the case.

2.17.4 Check that viewport(s) are zoomed to the correct scale.

2.17.5 Check all notes and dimensions.

Make sure that correct English Grammar have been used. Run a spell check.

Check the font and size of text.

Check that viewport boundary has not trimmed off any of the text/building; adjust the boundary to suit.

Check that the continuation notes (if any) are accurate and cross-referenced.

2.17.6 Check the title block in paper space.

Check that the title block has been filled in correctly.

The correct revision letter and date has been added.

The correct reason for issue has been added.

Have all of the necessary notes been added to the notes column?

If required, is the legend correct?

Has the location plan been hatched in the correct area?

2.18 Drawing Revision Procedure

Refer to Section 0.5

The drawings for the first issue of the Preliminary and Tender stages need to be signed by the relevant designer in the approved box and the revision box. Thereafter, the initials should be added to the approved box using AutoCAD and only the revision box needs to be signed by hand.



2.19 Outgoing CAD Issue Procedures

2.19.1 All CAD files to be issued by e-mail/CD/Memory Stick must be checked to ensure that:

All necessary reference files (xrefs) are attached / overlaid. All unnecessary reference files (xrefs) are detached and the file has been

purged.

2.19.2 Files may need to be zipped using WINZIP into a single ZIP file, encrypted and password protected. ZIP files will be named using the Building/Project name followed by the date of issue.

2.19.3 When sending drawings via e-mail, the correct drawing issue sheet must be attached. The drawings and issue sheet are to be included in the Zip File.

2.20 Incoming CAD Issue Procedures

2.20.1 All drawings to be sent to the University must be sent in a secure environment.

2.20.2 All files are to be unzipped within the incoming info directory.

2.20.3 All files must be virus checked before opening to ensure that there are no viruses attached. Open to ensure no corruption has occurred during transfer. However, this is an automatic process, and should require no user intervention.

2.20.4 Once the file has been opened successfully, any relevant drawings required to be used as an Xref shall then be saved into the folder using the same file name.

2.20.5 If the file is required for the project as an outline, it should be copied into the relevant MASTER DRAWINGS folder and named according to the standards. The drawing should then be altered to meet these standards and moved to ensure all outlines within a project have a common insertion point of 0.0.

2.21 Drawing Issue Sheet

The drawing issue sheet is to be used when issuing any drawings. All issue sheets are saved in the Project. Electronic copies of the Issue Sheets can be found in the following locations: S:\Facilities\Estates\Drawings\CAD\Issue Sheets

2.22 Standard Symbols Sheet

Electronic copies of the Electrical and Mechanical Symbols Sheets can be found in the following locations:
