PPD Examples

The only time I require the same page format throughout a project manual is when the owner dictates what it will be. We work with a variety of structural, landscape, civil, M&E, and other consultants, all of whom work with a variety of architects; forcing them to change formats for every architect does seem an unnecessary burden. If everyone used the same format, the project manual would look better, but, going back to previous discussion, the intent is communication, not appearance.

As long as the consultants’ specifications are readable, the only thing I require is that their headers and footers are the same as ours. That consistency is a clear benefit to the owner, contractor, and others who use the project manual, as the first information they look for - section number and title, page number, and project title, are in the same place. Once they get where they’re going, the content is what they’re after.

I don’t think changing page format is a problem, especially if you use styles, but I am amazed at how many of our consultants have problems. Especially surprising is how many administrative people, whose primary job is using a word processor, have mastered nothing beyond word wrap - and some don’t even understand that; I get documents from one source that contain carriage returns within paragraphs! I get specs from consultants and manufacturers who use spaces and tabs used to align text, a mix of automatic and manual numbering, and hard page breaks. Even when styles are used, individual paragraphs are often forced into the form of a different style. To further complicate the problem, some consultants are not consistent within their firms; some sections appear to have been keyed in by someone who knew how to use a word processor, while others obviously were done by a two-fingered hack.

This lack of knowledge is one reason I don’t ask our consultants to change their page format. Given the combination of more complex projects and reduced delivery time, I’d rather they concentrate on getting the content right. Another reason I don’t force our format on consultants is writing style. I’m of the SpecText school; I firmly believe that a terse style is superior to the verbose style used by many specification writers and MasterFormat.

I use short sentences and sentence fragments, which make it possible to use two-column format. All of our consultants use specs that are in a more narrative style - with lots of “contractor shall” phrases - which does not work well in two columns. Another common practice that requires a single column format is the use of many outline levels. The deeper they go, the greater the indent, and the less text you get on a line.

Our specs are based on a template, so when an owner does require a specific format, all I have to do is change the styles in the template and all of the specs automatically change to match. A little tweaking still is needed in each section, but all sections can be tweaked in just a few minutes, even less if a macro is used.

I began using a two-column format about ten years ago. After reading a few books about publishing, I tried several combinations of margins, fonts, and outline structure, and settled on one that worked well (maximum density without obscuring the message or hindering rapid reference). Within a few months, anecdotal evidence suggested I had made a good decision; I started getting comments from contractors and suppliers, who said they found the specs easier to read. With a terse style and two columns, more information appears on a single page. For the “sustainability” crowd, the number of pages in a section is often reduced. That sounds good, but the effect is not as great as it first might appear, as a section with an odd number of pages still needs a whole piece of paper for the last page. I wonder if anyone makes single sided paper. :wink:

Our firm has minimized the hassle by rigorous use of styles ad by the development of some Visual Basic code that allows us to update the files. If we were provided with a sample specification section that was organized in a similar manner life would be easy. The reality is that not all specification writers are sophisticated in the use of styles. As a result we have to create and edit a special .dot file for the project.

Other offices where I have worked did not have the knowledge to pull this off, thus the secretary was given the task of making it look right. As long as it looked right nobody worried how this was done.

Many of our clients are less flexible than Sheldon and while some clients will begrudgingly accept specification sections with a different format this is not something we find acceptable. If our format differs it often creates a negative impression by our client.

We have found Styles as implemented in Word, to be poorly documented and difficult to edit. Thus few individuals know how to create and edit styles.

The more we are asked to differ from what is shown in the PageFormat the more time it takes. Requests to change style of writing and sentence structure would cause us a lot grief. I imagine a two-column format would present us with a steep learning curve. There might be a point where we say no can do, but this is not something we want to say.

The reason I keep coming back to PageFormat is that it is the common origin of all customized formats. If we did not have it, life would likely be exponentially more difficult because the variations would be greater.

It seems the tendency to use customized page formats is inconsistent with the push for interoperability and the need to work with a common BIM files.

I hear the arguments how the formatting of specifications can make them easier to use. In the days when we did our drafting with pencil on vellum we composed the detail and used subtle variations in line width to make the drawings read. Some of these drawings were works of art. With the adoption of CAD and BIM this ability to compose our drawings has effectively been lost. The world sometimes changes in ways that require us to give up preferences in order to achieve other benefits.

So … back to the PPD. Word is, a Task Team is setting forth to work on this. For years, all we’ve had is the UniFormat book in hard copy or in a (why, I don’t know) Word Help File electronic format.

So we may now actually start seeing the PPD emerge as the useful tool it promises to be. Can anyone say “BIM?”

A UniFormat-based body of design data that can serve project communications and approvals as it develops, then evolve into MasterFormat-based contract documents: Priceless.

Revit has Uniformat (kind of) numbers embedded in the element properties. For example, The Exterior CMU Insulated Wall from the basic wall group is B2010144 I dont know where the 144 came from but the 2010 is correct.
So they are trying. I’ll dig up where they got the 144 But its not an abbreviation of either 042200 Concrete Unit Masonry or 042219 Insulated Concrete Unit Masonry.

Now If drawing in Revit, AND your draftsmen (or women) are thinking about the wall types. You should have a pretty good list of assemblies at the end of the day.

I was a premature poster! It appears that Revit is getting it’s Uniformat from R.S.Means.

I can confirm the rumor Phil mentioned, as I am chairing the PPD task team. We are just getting organized and are collecting examples of PPDs to find out just what people are actually doing.

The basic goal is to produce a new stand-alone guide that is more detailed and more helpful than the information in the PRM. Practicality is the watchword. In our first conference call meeting there was general agreement that the ultimate product should not be just another paper document, but some sort of electronic file that people can start using.

Of course, it will have to be flexible not only for appearance variations, but also for practice preferences. I have used a couple of different formats myself. My favorite, which I have used since the early 90s is a two-column table with the element number and name in the left column and a brief (terse!) description in the right.

I have had good success in getting designers to fill in the blanks of a Word template, which I then edit for technical content. Because UniFormat can function as a checklist, some designers have positively responded to using this form to clarify their own thinking about the project.

One of the issues for which we want to give some guidelines that the present PPD info is how to describe multiple wall types or structural systems in a single facility. For example, my previous firm did a lot of resort hotels in which the guest room tower had post-tensioned floor slabs, but the low-rise support and entertainment areas had concrete slabs on form deck.

We are also interested in the possibility of the element descriptions being directly linked to the objects in object-oriented CAD and BIM. That is, each object, whether large or small, or simple, complex, or multiplex, would have an entry in the PPD and vice versa. Schematic drawings could even use UniFormat numbering as keynotes. Im not sure how this would work with MPE elements.

Please feel free to send me full or partial examples of PPDs for use by the task team. For my friends who have not yet heard the news, I have moved to Nashville for family reasons and am now working at Gresham, Smith & Partners.

Louis,

Please send me your contact information to wayne.yancey@callison.com and I will send an excerpt from on I did.

I’ve been running into problems with PPDs for multiple-building projects, which is sort of an “extended version” of Louis’ issue. we not only have multiple wall types, we have multiple versions of them, because our project is 8 buildings (one of which is a basketball arena) plus landscape, and a subway station.

However, I think most of the formats out there fall down when you get to really really big projects, and the data management gets to be a discipline all its own. Even a relatively simple office campus: office buildings, parking structures; cafeteria plus conference space; and associated landscaping.

the PPD needs to be expandable and compressable. I’ve found that a PPD is used more often on large long range projects – it may be part of a financing pro forma (for example) and the information has to be discernible to a variety of audiences.
