Just got off the telephone with an MEP consultant who went on and on about why his firm has decided it necessary to write specifications under Divisions 20 and 24 - unnamed as yet by MF.
His firm’s made-up Div 20 sections have mechanical and plumbing content, Div 24 sections electrical.
He was not persuasive in his argument about why this is necessary. In fact, his reason for why his firm did this actually results in the SAME PROBLEM.
Has anyone else had to deal with this nonsense? I am insisting that the sections be located in their proper place(s) within MF2010.
did your company hire them? - tell them if they want to get paid they will do it your way.
or if you are being nice, tell them that most all of the division 20 stuff can be placed in plumbing or hvac and crossed referenced with VERY little effort or problem and the subs will just have to learn to read. which I know they can do as I have done this and they get all the info everytime.
The nonsense I get is where CAD jockies have mis-labeled dozens of drawings and details with the wrong spec Section references and the Project Director or even PIC asks me to change my specs to coordinate with the error “because it is easier”.
At least your MEP consultants is using and taking advantage of MF04 to it’s fullest potential. My MEP is using 5-digit MF95 and has created Divisions 17 and 18 and placed their louvers in Division 10.
I have been known to tell someone when they ask about the unused numbers in MF2004 that 36 is for “Orbital Construction”, 37 “Lunar Construction”, 38 “Martian Construction” and 39 “Deep Space Construction”.
What I don’t see very much in print is that MasterFormat 2004 was developed to be one of a number of data tables in OmniClass (UniFormat is another). MasterFormat is the data table for “work results”; there will be another data table for materials.
OmniClass is beginning to get more traction as the focus shifts to BIM because it can potentially offer the database structure that has been lacking in CAD software. This should reduce the cost of developing this part of BIM and offer a standard that can be used across software platforms.
Let me emphasize that I do not see this happening overnight, but development may accelerate because of the interest in BIM.
Those who invent their own systems because it “makes more sense” or “is easier” may well be shooting themselves in the foot in the long run. This is also a good reason when trying to assign a number to a new section that may be required to really try to understand the concept of “work results” not “products”. Where do we specify galvanized steel pipe? Depends on the work result; could be Division 05, Division 22, Division 24, Division 32, etc.
Robert Johnson, a frequent contribution to this discussion group, has been involved with OmniClass and may be able to offer more specific information.
Can someone point me to a discussion to help people [who are not necessarily specifiers] understand “work results” versus “products” as a concept in naming sections?
ISO Formal Definition of Work Result:
Construction result achieved in the production stage or by subsequent alteration, maintenance, or demolition processes and identified by one or more of the following: the particular skill or trade involved; the construction resources used; the part of the construction entity which results; the temporary work or other preparatory or completion work which results.
Go to OmniClass website, Table 22 for a discussion of the concept.
Basically we don’t specify products in isolation except when it is a purchase contract. We specify the resulting construction using the product(s) in place within the construction. We usually specify multiple products in a section: CMU, mortar, joint reinforcement, anchors, etc. Even if a specification section centers on just one product like a window, it almost always includes supplementary or accessory products that are needed for its installation. Although specifications include product specifications; they also include what is required to have those products in place in the completed construction. That is a work result.
MasterFormat has always classified work results; we just never analyzed it deeply until we were working on the OmniClass tables and the 2004 edition of MasterFormat at the same time. It was then that we realized that MasterFormat was not a system to classify products even though many have used it for that - there is not one location for many products in MasterFormat. Many products can be used in multiple work results. Peter gives one example of galvanized steel pipe.
Another case in point - vapor barrier at SOG. We are not specifying the sheet material as a product. We are specifying a barrier in place to restrict the tranmission of vapor from the substrate below. We may specify it separately in Div 07, with the concrete slab in Div 03, or with the earthwork in Div 31. Also there are other applications of vapor barriers - exterior walls, climate controlled rooms, roofing. The vapor barrier products for the different locations will likely be different and may be specified in different locations.
We took the opportunity of working on OmniClass and MasterFormat 2004 at the same time to explain and promote this concept.
Someone (it may have been Bob Johnson?) once described this way, and I still use this example in my class:
The bricks, mortar, ties, reinforcing and so forth stacked on the jobsite are materials - the brick wall is the work result.
Ken Guthrie is the father of what became the OmniClass tables. He had the vision to see the value of a system to classify everything in the built environment and promoted that idea for several years in the late 90s. It resulted in the formulation of a group to try to do that a few years later. The group included many CSI people but it was not a CSI committee or task team but did receive CSI staff support. People came on their own dime.
The group ended up using some international ISO standards that had been working on the came concept. The concept was based on looking at the built environment from many different views you could classify things different depending upon how you were looking at them do you classify a constructed facility by its form or it function? Obviously you can do either so you will see a table for each view in OmniClass. It is easy to see how our two existing classification systems (MasterFormat and UniFormat) fit into the system viewing construction on the materials and methods used (MasterFormat work results) and the function of the construction element (UniFormat functional elements). These two systems are included in OmniClass but not completely MasterFormat Divisions 00 and 01 and UniFormat Introduction and Element Z are not included because they relate to uses of the formats rather than specific construction.
It is always interesting to see how some visions have later results not envisioned at their birth. OmniClass was envisioned to have many uses by many different participants in the design/construction industry. BIM was just coming on the horizon at the time and was not seen as one of those uses much different looking at it a few years later as BIM is becoming an ever larger force in the industry. OmniClass has been and is currently being expanded and revised in the last few years to improve its use in the BIM process for the classification and exchange of information.
Put yourself back in the early 60s people preparing specifications organized them in many different ways to suit their personal fancy. Some CSI leaders had the vision to have them organized in a common manner for the benefit of all the participants that have to deal with specifications from many different sources product reps and manufacturers, subcontracts, contractors, consultants, etc., etc. Think where we would be today if those leaders didnt have that vision we would still be in chaos!
Now think how communication has changed from those days with all the electronic exchange of information much more information accessible in ever increasing speeds. The more this information is organized in a common manner, the more benefit. The more it is organized differently by the originators, the less benefit spend more time trying to find and understand what you need. Peters point about across software platforms is especially pertinent. Again think about all the people who deal with that information from multiple sources on multiple projects what a benefit a common organizational structure is.
Now we all like to organize information in our own favorite ways if only I was the God of all organization of design/construction information what a great world it would be! The more we organize information differently, the more difficult we make it for others who receive and use the information we produce. Conforming to a common organizational structure for design/construction information will be a great benefit to the total industry especially in the emerging world of BIM and the ever increasing electronic exchange of information.
Sometimes we get to caught up in the little things like how we think a particular subject should be classified - we make a big deal out of one item in a total system (that doesnt mean that classification systems should not be reviewed, revised and expanded to meet the users needs). We need to look at the total big picture as the most important. Conformance to a classification standard is very important to all the other people we communicate with. If you think the standard should be revised, get yourself involved the next time it is being reviewed and revised.
I have always liked the Canadians reaction to MasterFormat 2004 Its just numbers!
Bob,
Being a Canadian, your quote should be “It’s just numbers, EH!”
As I am told by my American friends on numerous occassians Canada is spelled C EH N EH D EH.
My license plate on my Road King is EHTEAM as in the A TEAM. Canadian Customs at the WA and ID border crossing enjoy the humor.
Having been the manager of a Denver office of a Canadian contractor back around 1970, I had a relatively early exposure to those north of the border. The “language barrier” was always a source of some fun.
I remember the early days of the SPECTEXT review committee dealing with Wayne Watson on a regular basis. I remember him submitting a new section for review - my response as chairman was "This looks pretty good as soon as we get the “Canadianese” out of it!
I have some favorite products that I like to use to talk about products vs. work results. I have already mentioned galvanized steel pipe. We use it in 05 50 00 “Metal Fabrications” 05 52 13 “Pipe and Tube Railings”, 22 11 00 “Facility Water Distribution”, 23 21 00 “Hydronic Piping and Pumps”, 32 31 13 “Chain Link Fences and Gates”, and 32 84 23 “Underground Sprinklers”. Plastic laminate is specified in each section where it is used as a finish on a “work result” like cabinets (Div 06), paneling (Div 06), toilet partitions (Div 10), or countertops (Div 12). Stone is used for different types of Div 04 stone masonry; stone tiles, flooring, and facing in Div 09; stone countertops in Div 12, and stone paving in Div 32. Bullet-resistant composite glass fiber panels are used in cabinets in Div 06; hollow metal, wood, and aluminum doors in Div 08; and drywall partitioning in Div 09.
In think about MasterFormat in terms of work results, it helps to clear up why we have a Division 05 Metals, but steel and aluminum doors and frames are specified in Division 08 Openings. I very clearly remember trying to puzzle this through when I was reorganize a product library in the mid 1960s in one of my first summer jobs working for an Architect.
We also have “metal” items in almost every other division (steel reinforcing in Div 03 and 04, flashing in Div 07, partition framing in Div 09, you get the idea); however, the “work result” is different.
Very good examples Peter.
Yes Indeed.
Why subject a poor splash block that sits beneath a drain pipe from a penthouse roof to a main roof to a lonely life as the only precast concrete on a project in DIVISION 03 when it really wants to be with its friends in DIVISION 07 Roof Accessories; or a concrete wheel stop for a parking garage that just wants to be a Parking Accessory.
The real light bulb moment is when they want to substitute wheel stops made out recycled rubbery stuff. So much wasted effort to get it out of Concrete.
So division six is a mess. Finish Carpentry and Paneling should be in Division Nine, Finishes. We have Cabinets and Counter tops in Division 12, but they are almost always specified in division 6. I would argue that they belong in division 10 under storage. Division 12 shouldn’t include permanent parts of the building.
I could go on, but the point is that division 6 isn’t about work results at all. If you want to organize around work result there shouldn’t be a section titled “Wood, Plastics, and Composites.”
I have noted similar discrepancies throughout my career (I started using CSI’s UCI in 1968). The kitchen cabinets in my 9-year old home were site-built by a carpenter (and finished using about the highest VOC paint around) so I am comfortable with them being specified in Div 06. Much of this stuff used to be produced on site using skilled craftsmen. As we have recognized the benefits of shop-built work (better quality control, greater quantities, economies of scale), such items begin to look more like applied finishes (or installed furnishing) than site craft work.
Althoug one can make a case for metal fabrications and pipe and tube railings being “Metals”, “finish items” such as decorative railings (sometimes with almost no metal components), formed column covers, and decorative metal cladding for doors and windows, would seem to belong more in Div 09. I personally believe that “polished concrete” is a finish process done by people who don’t have anything to do with placing concrete and deserves a section in Div 09. (I have been over rulled.)
As a practical matter, however, Div 09 is already packed full of stuff that probably should belong somewhere else. What does a shaft wall system have in common with a high performance coating? One would think that formed metal column covers really had more to do with other types of applied finishes (like stone and wall covering).
At the end of the day, dispite the best efforts of everyone involved over the now approaching 60-year history of MasterFormat to be rational and consistent, there are some items that carry the residual of the past. As one of my Jesuit mentors used to say, “Sometimes, you just have to sit back and adore the mystery.” unless you want a committee or task team assignment from CSI.
As we lurch toward a standard database structure for BIM projects, we can tweak a particular component standard, but it seems to be that we really have to keep our eyes on the overall goal.
Why should a non engineer care how a MEP consultant chooses to do his specs? If you are so obsessed with “work results” let the man do his work and be responsible for his results.
So if you are drawing on 30 by 40 inch sheets, the MEP consultant can use 24 by 30? and use Spanish instead of English (because the MEP subs in his areas all speak Spanish).
Adherence to standards is an indication of professional competence.
Oh, gee, I don’t know - maybe because the MEP’s Agreement with the Architect REQUIRES him to produce documents in the manner required by the Architect?
Because maybe, just MAYBE, bidders know to go to Division 26 for Electrical and Division 23 for HVAC but would likely regard made up Divisions 20 and 24 as mistakes/not applicable to them/confusing/Change Order treasure troves?
