Drawing Numbering System - Chert 2005

CHERT – Proposal for discussion Drawings - Numbers and Titles Any system of drawings needs clear and easy identification in the future – Drawings would be searched for by identifiers such as:– •

Location

•

Name of site

•

Title of Drawing

•

Revision number

•

The latest or most up to date version

Location Each site we have identified has already been allocated a unique number by Vince, within the Chert Sites and Monuments Record Number System. • •

•

This is not the same as the Somerset County HER numbers, as Somerset will only enter a site when clearly identified for listing. In the future I suspect all CHERT sites will be folded into Somerset’s HER, so we need at an early stage to eliminate any conflicts, but at this stage I suspect fewer problems in the future by using Vince’s system exclusively.. Each site within Vince’s system is identifiable from a grid reference, so site number and connected drawing archive can be readily identified.

Site Name We have been using a ‘shorthand’ that comes from frequent use, familiar to regulars, but fairly incomprehensible to newcomers, or someone in the future researching CHERT’s archive. Could I suggest:•

Field Names be those on the Tithe Maps, or those within the Charterhouse Estate as shown on Sam Driver’s 1761 survey of the estate. I can provide a set of 7 No. A4 photocopyable sheets showing these names (hopefully correct) from my project, unless Vince has an easier alternative.

•

Specific sites be named, such as a lead works or a named barrow. A key plan will be essential, to be prepared showing the location of these named sites, with the agreed name.

Title of Drawing This may seem obvious, but each drawing will be showing a unique aspect of the site, a survey plan, a sketch plan, a section, or a detail. The name should illustrate this.

Revision Number In many cases a drawing may be issued or used before it is completed, or later work may result in revision or even redrafting. Here is a real problem, as any user must be able to be sure they are consulting the latest or most up to date version. To control this does, sadly, need some disciple – •

Once a drawing is issued or used, then its number should become unique at that point.

•

If further work is done on that drawing, then a revision number would be added.

•

A note of this change must be made in the drawing register.

Drawing Register We must start a drawing register, listing all the drawings within the CHERT archive, which it will be the duty of everyone to maintain. Anyone producing a new drawing should – •

Name and number the drawing consistent to the simple system.

•

Enter the number and name into the register.

•

When used or issued, note this in the register

•

When altering a drawing, check with the register, and if it has been used in the earlier form add a revision letter to the number.

•

The register should be accessible to everyone, preferably in a hardback notebook to be held in the CHERT room at Charterhouse.

Conclusion Every drawing or revision of a drawing must have a unique identifier, clearly shown on the drawing and agreeing with the entry in the drawing register, comprising two elements – Drawing number, comprising SMR Number from the CHERT archive Drawing reference Revision number e.g. 654/3/C – Site 654, third drawing, revision 3 Site Name, and detail name e.g. Cowleaze Enclosure - Section through embankment Cowleaze Enclosure – Geophysics run 23 If known it is also useful to include correlation with other drawings.

Examples – Typical of the various drawings I have done with CHERT World War II Bunker at Tynings Gate – SMR Ref. 38 • The survey drawing on film was not numbered at the time and should have a number added. The first drawing produced for the site. Suggested name – Survey No 38 •

The tracing of the plan for reproduction produced two A4 drawings Survey of World War II Bunker - Plan, No 38/1 Survey of World War II Bunker - Elevations, No 38/2

World War II Bunker on east end of Blackdown – SMR Ref. 191 • The survey drawing on film was not numbered at the time and should have a number added. The first drawing produced for the site. Suggested name – Survey No 191 •

The tracing of the plan for reproduction produced three A4 drawings Survey of World War II Bunker, Ground Plan - No 191/1 Survey of World War II Bunker, Layout Plan - No 191/2 Survey of World War II Bunker, Elevations and Location - No 191/3

Cowleaze Enclosure Here I had no idea of the SMR number etc. so this needs renumbering. The original survey was on at least three boards, so the survey drawings need to be numbered. The tracings at full size on film also need to be numbered. I also produced A4 versions for use, and there are at least four versions of this in existence, which at the time I numbered MFE 1 to 4, standing for ‘Manor Farm Enclosure.’ All these need entering into a coherent system. Rowbarrows just South of Chancellor’s Farm The three barrows SMR refs are 465,466 and 467 – Again the three survey films are un-numbered as are my inked in drawings. 5 No Reproduceable A4 drawings numbered – Survey of Barrow, SMR ref 465, Chancellor’s Farm – Dwg. No 465/1 Survey of Rowbarrow, SMR ref 466, Chancellor’s farm – Dwg. No. 466/1 Survey of Rowbarrow, SMR ref 466, Earthworks Eat of Rowbarrow – Dwg. No. 466/2 Survey of Barrow, SMR ref 467, Chancellor’s Farm – Dwg. No 467/1 Survey of Barrow, SMR ref 467, Chancellor’s Farm – Dwg. No 467/2
