The structure of working drawings

Every set of working drawings consisting of more than one sheet is structured, for it represents a more or Drawings showing the extent of each trade's involvement. A 'construction manual' describing, by means of annotated drawings, the way in which each trade is to operate and which is explicit enough to ensure that no local querying or decision-making will be necessary. An objective and realistic description of the quality standards required and the methods to be employed. Drawings giving an...

Architectural CAD packages or programs

Other programs may use different terms.) These are CAD programs with capabilities beyond the drawing of simple lines, arcs and text. They have additional capabilities specific to the architectural and building industries and usually allow a 3D model of the building to be created from intelligent 'objects' rather than simple entities. Attribute A special type of text entity, included within a block definition that can be used to hold information about that block....

What does it cost

As to the cost of introducing (and indeed of operating) new drawing methods one is on less certain ground. Certainly all the available feedback suggests that it is unusual for a practice to revert to unstructured working drawings once it has started producing structured sets, which seems to indicate that at least the structured set is not so overwhelmingly expensive to produce as to render it uneconomic in practice. Short of carrying out parallel drawing exercises using two methods and...

Conversion alteration and rehabilitation

It is now necessary to look at the methods described previously and to see how far they are applicable to the description of work to existing buildings. To dispose of the simple matters first, straightforward extensions to buildings present no problem. They are in every respect new pieces of building and there is no 3.24 The openings schedule shown in 3.21 extended to give information about ironmongery sets reason why the methods adopted for any other new building and the conditions relating to...

Circulation

The greater the use that is made of the drawing register the more important does it become to exercise proper discipline in its maintenance and circulation. In particular, it is a useful procedure for the up-dated register (and those of the other consultants) to be copied to all concerned at regular intervals e.g. on the first of each month, or as part of the site meeting agenda so that all team members are aware of the up-to-date position. This is of even greater importance when drawings are...

Other peoples drawings

When other consultants are circulating CAD files their receipt should be registered and filed under the recipient's own file storage system. The proper recording and storage of incoming drawings however often presents a problem, particularly when their numbering system bears no relation to the structure of the architect's set. Should one open up an incoming drawings' register for each consultant and manufacturer, laboriously entering drawing titles and number and date of receipt Should one even...

Activity drawings

The provision of a new door in the existing brick wall, given as an example in the section on conversions and alterations, was an instance of an activity-oriented approach to the provision of building information. Activity 1, involving the cutting of the opening and insertion of the lintel, was rightly regarded as being distinct and of a different nature from activity 2, which embraces the fixing of a new door and frame. The two activities were separate and complete in themselves they were...

Materials for manual draughting

Detail paper has the great advantage of being cheap and, because it offers a semi-opaque background, pleasant and satisfying to draw on, particularly in pencil. It is best suited to the preparation of drafts for subsequent tracing into final drawings, where the original sheet may be expected to have a limited life, and where any prints taken from it will be for internal exchange of information among team members, and also for rapidly produced pencil details (accompanying architects'...

Key detailing in draft stage E

At the completion of stage E there should be a carefully thought out solution available for every construction problem that can be envisaged this will involve the production of a sheaf of draft details in which the principles of these solutions are established. The drafts will not be elaborated into final drawings. They will remain as source documents and the decisions they embody will be fed out into various stage F drawings or computer files if CAD is being used for detailing. General...

The sequence to take

There are several degrees of rationalisation and they should be introduced in sequence Standardise drawing size and format for all new projects entering production drawing stage. Rationalise new projects into the general arrangement, assembly, component, sub-component, schedule format. Select one such project for the experimental application of CI SfB (or Uniclass) coding and let it run through its production phase before attempting a general application of the...

Grids

The use of shadow grids has been around for a long time, particularly among the manufacturers of building systems, where components tend to be modular and junctions simple and standardised. They are applicable to traditional building as well however, whenever a modular discipline exists, and when used with discretion can speed up the production of drawings and reduce the need for elaborate dimensioning. The superimposition of grids presents no problem with CAD, as they can be assigned their own...

Structuring by building element

Within the framework of a primary structuring by information type, the information to be shown is subdivided by building element and this constitutes the secondary structuring of the drawing set. To establish the possible means of achieving this we should start by looking at the various ways in which the building fabric may be regarded. Consider the diagram in (1.19). It is difficult to visualise any space-enclosing structure, no matter how primitive, which does not possess elements falling...

Introducing new methods

When Working Drawings Handbook first appeared in 1982 the concept of structured drawings was alien to many drawing offices. Their number has now diminished, but the following notes are intended for offices which have still not taken the plunge. The introduction of structured drawings into an office which hitherto has managed without them requires some thought. There must be many offices which, whilst agreeing in principle that their work could be improved by rationalisation of their working...

Trade literature

The rationalised drawing structure provides a convenient framework on which to hang manufacturers' literature. There is no virtue in redrawing the builders' work details printed in Bloggs & Company's catalogue when a photocopy or scanned image suitably overcoded with the job and drawing number will convey the information more cheaply and accurately. (Bloggs & Company are not likely to object to the resultant wider distribution of their literature.) Indeed, a number of manufacturers will...

Status coding

As has been noted earlier, many drawings perform different functions at different stages in their life, and some system of identifying their function at a given moment is a useful adjunct to a coding system. One such method is to use the letter reference of the appropriate RIBA stage of work in conjunction with the drawing number, as follows E Detail design drawing. Any working drawing up to the time it is frozen for issue to the quantity surveyor, when it becomes G Drawing reconciled with...

The topography of the site, with both existing and finished levels. 2.22 A typical site plan. Information is given about new and existing levels as well as directions as to where other information may be found. (The information about levels is given here because the plan is to a sufficiently large scale and the small amount of earth moving makes it unlikely to form a separate...

Priorities

In framing the stage F programme certain priorities will emerge. Clearly, the establishment of the basic set of general arrangement plans is fundamental, for they will form the basis for elementalisation of subsequent general arrangement plans and of other consultants' work. After that the priorities will probably be dictated by the needs of the quantity surveyor. An elemental format makes it easier to group the issue of drawings into separate packages e.g. internal joinery, finishes, etc., but...

Some principles affecting scheduling

Their primary function is to identify and list components possessing common characteristics e.g. windows, doors, manhole covers, etc. They should not attempt to provide comprehensive information about the component they should serve rather as an index to where the relevant information may be found. They should initiate a simple search pattern for the retrieval of component, sub-component and assembly information. They are only worth providing if the component in question has more than one...

Drawing

The types of drawing which make up the complete set having now been identified, the following two chapters look at them in sequence to see the sort of information that each should contain. A brief reference must be made here, however, to the means of producing them. 1 Drawing them manually, by means of ink or pencil on tracing paper. Until relatively recently this was the only available method. 2 Drawing them electronically on a computer screen using a mouse and printing the result. This is...

Hand lettering

With the pre-eminence of CAD this tends to be a dying skill. But even in the fully automated office there is from time to time the need for a manually prepared and lettered drawing, if only to provide the site office with an urgently needed detail. Such occasions demand a lettering style which is both rapid and legible. Figure 4.21 shows a recommended sequence of strokes in the formation of individual upper case letters.

Such a meeting should cover the following points 1 Introductions. Individuals in each organisation must be named as the link men through whom information is to be channelled. They should be of sufficient standing to be able to act and make decisions responsibly and with authority and, if possible, they should be of comparable standing within their own organisations. It is unhelpful to the project for a young project architect to be out-gunned by the senior partner of the engineering...

General arrangement plansformat

With very small buildings it is perhaps pedantic to ask that each of (two) plan levels be presented on a separate piece of paper when both fit happily one above the other on a single A2 sheet. In general, however, it is desirable that each sheet should be devoted to one plan level only, the size of the building and the appropriate scale determining the basic size of sheet for the whole project. Leave plenty of space on the sheet. Apart from the fact that this tends to get filled up with notes,...

Subcomponent drawings

These have a limited use and often the information they convey will be better shown on the component drawing. There are instances, however particularly when a range of components is being dealt with of which the sizes and appearance differ but the basic construction remains constant when it may be more economical to present details of the construction on a separate drawing. For example, 3.9 shows two doorsets of different sizes and types. The basic sections from which they are fabricated are...

Various plastic cut-out templates are on the market, covering many of the symbols given in the appendices. Templates are also available for the production of circles and ellipses and for drawing sanitary fittings.

A word of warning should be added about the indiscriminate use of templates for sanitary fittings, where it is...

The plan of work

Since what we shall be looking at is in effect a series of disciplines, and since the plan of work is the overriding discipline into which the working drawing process is integrated, it is probably worthwhile reminding ourselves of it at the outset. Table I of the outline plan of work is given here in its entirety. Frequent reference to the plan of work will be made in this book, for it is important that stage F production drawings should be seen in the context of the whole architectural...

Library of standard details

Many practices attempt, at some point in their existence, to crystallise the accumulated wisdom and experience of the practice into a set of standard details, only to find with increasing disillusionment as they proceed, that not nearly so much is really standard as was at first supposed, and that the very existence of a standard drawing which is nearly (but not quite) applicable to the project in hand is a dangerous inducement to compromise. 5.4 Manufacturer's catalogue gives precise fixing...

We have covered the structure of a set of working drawings, the hierarchic progression of location, assembly, component, sub-component drawings and schedules. We now have to look at how the drawings themselves are to be prepared, in a form that will be economical of drawing time and will enable multiple copies to be taken for the use of the contractor, sub-contractors, quantity surveyor and others. There are two primary methods for producing the originals 1 They may be created on a computer...

Production drawing programme

The production drawings, if properly structured so that a predetermined amount of information is conveyed in them, should be the simplest aspect of the architect's work to quantify in terms of time taken. Having established the list of drawings, it is better for two of the more experienced people to make independent assessments of the time that should be taken over each drawing and to compare notes afterwards. Factors of personal optimism or pessimism may thus be discounted, and a more...

Changing roles

Changing the roles of the profession and the industry may well be desirable, but it is a long-term process and not the function of this book. The best must be made of the present situation. It is therefore incumbent on the architect to acknowledge his management function as coordinator of the professional team, and he must accept responsibility for ensuring that the structural engineer is aware of M & E requirements, and that M & E are equally aware of structural constraints. In an...

Statutory approvals

A chicken and egg situation this one you can't get approval until you've submitted the drawing it's pointless preparing the drawing until you've got approval. But visits to the fire officer and the building inspector in the early stages of the scheme will not only set up lines of communication which will be invaluable for the future but will establish principles for incorporation in subsequent detailing. It is a firming-up process. It is essential to know at the start of stage C the spacing of...

The structure of Information

No one who has delivered drawings to site and overhead the foreman's jocular reference to a 'fresh set of comics having arrived'will deny that the quality of architects' working drawings in general is capable of improvement. In some measure we have all of us suffered more or less justifiable accusations of inaccuracy, inadequacy and incomprehensibility and yet drawings are prepared and issued with the best of intentions. Few offices deliberately skimp the job, despite economic pressures and...

Line thickness

Line thicknesses offered by the manufacturers of technical pens cover a wide range. Figure 4.1 shows them at full size. It will be noted that there are two ranges available, Range One being the most common and Range Two based on German DIN standards. With Range Two each size doubles the thickness alternately preceding it, with the result that alterations may be carried out to an enlarged or reduced copy negative in a similar weight of line to that appearing on the original. (This applies...

Annotation of the drawing

Adding text to a drawing presents few problems when working with CAD. Modern CAD programs, connected to laser printers or inkjet printers, will have access to all the fonts installed on the operating system. There is a huge choice of styles, any of which might be used for text notes in the drawing. But remember that the aim of text is to convey information clearly and concisely. Don't go overboard with too wild a font style and do use a size that is big enough to read on site. Imagine that a...

Drawing sheet size

The international 'A' series of paper sizes is now universally accepted, and all drawing and printed sheets used in the office will conform to its requirements. It originates in the ingenious concept of a rectangle having an area of 1 m2, the length of whose sides are in the proportion 1 V2 (4.4). The dimensions of this rectangle will be found to be 1189 x 841 mm and by progressively halving the larger dimension each time, a reducing series of rectangles is produced, in which the proportions of...

Specification

The function of the specification in relation to a competent and comprehensive set of drawings may be defined quite simply. It is to set out quality standards for materials and workmanship in respect of building elements whose geometry, location and relationships to one another have been described by means of the drawings. It follows therefore that in a properly structured information package neither specification nor drawings should trespass upon the other's territory. If the drawing calls for...

Drawing overlay method

Each element of the design is drawn on its own unique 'layer' within the computer file, walls on one layer, dimensions on a second, electrics on a third, radiators on a fourth, and so on. Layers can be turned on or off as needed. During the design process both electric and radiator layouts might be turned on, enabling electric sockets behind radiators to be spotted. The concept of layering is common to all CAD programs. Different programs might use different...

General arrangement sections

General Arrangement Plans

General arrangement plans in effect constitute a series of horizontal cross-sections through the building, spaced out so that one is taken at every floor level. This spacing is reasonable, since in practice the appearance of the horizontal section is most likely to differ from floor to floor and unlikely to differ between floor and ceiling. 2.16 Elevation as a secondary reference to window components. The reference S 31 leads back to the external seconday elements schedule, where the components...

The following comments may be helpful in establishing the correct approach to dimensioning such diverse drawings as the site plan, primary element general arrangement plans, general arrangement and assembly sections, and component and sub-component details. To set out a building it is necessary to establish a datum parallel to one of the building's axes. The criteria by...

Roof plans

Roof Level Plan Cad

Roofs particularly if they are flat roofs are essentially just another floor and it might be thought pedantic to introduce separate codes for them. Admittedly quantity surveyors and others concerned with elemental cost analysis require the distinction, but drawing codes do not always help here. Is 2.11 a roof plan of the factory, for example, or is it a floor plan of the tank room It should be treated as a floor plan and coded accordingly as 'level number . . .'. This method of referring to all...

Uniclass Table G

This is the system set out in the 2003 CPI Code of Procedure, and as such has the advantage of being consistent in its terminology with the Common Arrangement of Work Sections. The National Building Specification operates under the Common Arrangement.

Uniclass Table G Table II is an attempt to reconcile these divergent objectives,...

An alternative method is in existence which fulfils most of the requirements of an elemental structuring system and which has the advantage of being already well established within both the profession and the industry. This is the CI SfB method of classification, and while it has its detractors, who legitimately point to certain weaknesses in detail, it has so many advantages in logic and flexibility that on balance it must be recommended. The CPI documents accept it as a viable alternative to...

A decision was made at about the same time in relation to the smaller and simpler Project B to sub-divide the primary elements to a greater degree. Since the reasons for arriving at...

A component may be defined as any item used in a building which emanates from a single source of supply and which arrives on site as a complete and self-contained unit, whose incorporation into the building requires only its fixing to another component or components. Thus, a window is clearly a component, as is a manhole cover, a door, a section of pre-cast concrete coping, a mirror. So, for that matter, is a brick. A brick wall would be an assembly. Two types of component should be...

The advantages of room-by-room scheduling as a medium for conveying information about internal finishes and fittings have been noted earlier. The gradual collection during stage E of such information into a source document of comparable format will clearly assist in the preparation of such schedules at stage F.

The drawing register is a key document in the proper organisation of a working drawing project and as such needs to be something rather more than the loose sheet of paper with a scribbled list of drawing numbers and titles which sometimes suffices. After all, it serves a multitude of purposes, being at various times a declaration of intent, a record of performance and, in the event of dispute on abandonment of the project after commencement of the working drawings, possibly a legal document. In...

Electrical symbols

The architect frequently becomes involved in the production of electrical layout drawings, particularly on smaller projects where no M amp E consultant is engaged, and Appendix 4 gives some of the more commonly used symbols in general practice. Two points may usefully be made about the method of showing wiring links between switch and fitting. In the first place, of course, any such representation on the drawing is purely diagrammatic no attempt need be made to indicate the precise route the...

What it does is present this information in a more disciplined and readily retrievable form. A list of...

Size of drawing office team

Stage Production Information Drawings

The right size and structure of the team is all-important, and in many ways it is a case of the smaller the better. Any increase over a team of one starts to invoke the law of diminishing returns and as the numbers increase so do the problems of control and communications. On the other hand, the diversity of work demanded by most building projects coupled with the constant and remorseless pressures of the overall programme mean that too small a team lacks the necessary flexibility of response....

Homemade systems

It is not difficult to devise your own systems to meet these requirements. Indeed, in practice many offices do, varying the method each time to suit the complexity of the job in hand. Within the primary general arrangement assembly component framework, for instance, it is possible to divide the drawings on a small project into, say, brickwork series B , windows series W , doors series D , etc. The precise method of sub-division and of coding is of less importance than recognising the existence...

Pictorial views

The use of perspective sketches, axonometric and exploded views should not be overlooked as a means of conveying information which might be difficult to document in more conventional forms. The ability of CAD to produce three-dimensional information is of obvious benefit here.

Photographs of existing buildings are invaluable to an estimator when 3.21 Useful format for...

In the same way that line thickness is influenced by considerations of scale and the relative importance of the objects delineated, so too is the degree of detail by which various elements are represented.

Design team programme

It is essential for the work of the entire design team to be integrated into a comprehensive programme, and unless a specialist programmer forms part of the team and this is almost a sine qua non for any very large or complex project then the management role of team coordinator falls to the architect. Of all the consultant team an architect is probably best fitted by virtue of his training and other duties to exercise the skills required, and should take advantage of his position as team leader...

Outline specification

The case is argued elsewhere in this handbook for a specification which is an integral part of the production documentation rather than the afterthought which puzzled site staff often assume it to have been. If drawings are to be freed of the detailed written descriptions they are frequently made to carry, it is implicit that this information must be conveyed to the contractor by other means. Indeed, the philosophy of the National Building Specification is reliant upon the geometry of the...
