Overview, systems, Masterformat, Uniformat
Review course outline, description, and policies. Describe architectural systems in general.
Basic division into structure, enclosure, mechanical/electrical services, and interior systems.
This diagram shows the four primary building systems, all supported by the structure.
This diagram from Stewart brand's How Buildings Learn shows six layers, all of which change at different rates.
Difference between traditional and modern building strategies: modern systems tend to be more layered, optimized, pre-engineered.
Implications of division of architecture into "art" and "science."
: Need for organizational standards (see this ComputerWorld article
for an example of a dysfuctional array of competing standards).
1963 -first attempt at organization based on building trades, construction methods.
1978 - integrated with project manual (bidding, contracts, conditions) plus 16 specification divisions.
1986 - adopted by Sweet's
1987 - adopted by R.S. Means (cost estimating)
1995 version has 5-digit format: 0 2 1 0 0 for example, where 0 2
is the "division" (e.g., site work) and the following 3 digits indicate either broad scope (e.g., 100 - site preparation), medium scope (e.g., 110 - site clearing), or narrow scope (e.g., 115 - selective clearing).
Critique of masterformat:
- problems adjusting to changing technology and cultural construction practices; systems may transcend "products" or "material" categories. E.g., EIFS 07240 contains insulation, mesh, fasteners, etc.
- ambiguity: should reinforcing steel be filed under metals (05) or concrete (03)? If concrete, with cast-in-place (03300) or with concrete reinforcing (03200)?
- problems with material versus functional organization: e.g., where does roof insulation go? With membrane roofing (07500) or with roof insulation (07220)?
- new technologies are invented, or become more important, requiring more explicit attention (e.g., electronic security systems, now with its own division number).
- in general, there is a confusion in finding a unified organizing strategy; instead it is based variously on the following:
- construction sequence, e.g., concrete before masonry
- construction trades, e.g., doors and windows (now "openings")
- construction materials/products, e.g., masonry
- construction systems, e.g., thermal and moisture protection
2004 version replaces 5-digit with 6-digit scheme.
Divisions now called "level one" titles. There are 3 such levels, each with 2 digits (plus possibility of using 1 or 2 additional levels).
Each level describes in greater detail the so-called "work result," defined as traditional construction practices that result from the application of skills to construction products or resources.
0 3 2 0 0 0 is now concrete reinforcing (versus 1995 version's 03 2 0 0). The various levels are as follows:
|0 3||2 0||0 0|
|division or level one||level two||level 3|
Level four may show up as follows, after a dot: 0 3 5 2 1 6 . 1 3 referring to lightweight cellular insulating concrete.
Note that the Masterformat "hierarchy" is a bit strange: for example, the path to 0 3 5 2 1 6 . 1 3 goes like this: 03 00 00 Concrete --> 03 50 00 Cast Decks and Underlayment --> 03 52 00 Lightweight Concrete Roof Insulation --> 03 52 16 Lightweight Insulating Concrete --> 03 52 16.13 Lightweight Cellular Insulating Concrete. It is important to realize that 03 52 00 is actually a subset of 03 50 00.
Another way to understand the formating of Masterformat is to place it in "outline" form, for example:
[02 00 00] Existing Conditions
[03 00 00] Concrete
- [03 10 00] Concrete Forming and Accessories
- [03 20 00] Concrete Reinforcing
- [03 30 00] Cast-in-Place Concrete
- [03 40 00] Precast Concrete
- [03 50 00] Cast Decks and Underlayment
- [03 51 00] Cast Roof Decks
- [03 52 00] Lightweight Concrete Roof Insulation
- [03 52 13] Composite Concrete Roof Insulation
- [03 52 16] Lightweight insulating concrete
- [03 52 16.13] Lightweight Cellular Insulating Concrete
- [03 52 19] Lightweight Aggregate Insulating Concrete
- [03 53 00] Concrete Topping
- [03 53 13] Emery-Aggregate Concrete Topping
- [03 60 00]Grouting
- [03 70 00]Mass Concrete
[04 00 00]Masonry
[05 00 00]Metals
In the new (2004) Masterformat scheme, there are many more divisions (potentially 49 rather than the old 16), organized in the following hierarchy:
- Procurement and Contracting Requirements Group
- [no subgroups in this category]
- Division 00 Procurement and Contracting Requirements
Contains things like title page, table of contents, advertisement for bids, information about pre-bid meetings, preliminary schedules, and so on.
- Specifications Group
- General Requirements Subgroup
- Division 01 General Requirements
Contains things like payment procedures, work covered by contract vs. by owner, summary of contracts, allowances, alternatives, any temporary facilities, change orders, periodic observation of work, and so on.
- Facility Construction Subgroup
- Division 02 Existing conditions
Contains things like subsurface investigations, surveys, assessment of existing masonry, concrete, or other materials on site, demolition, remediation of contaminated site conditions, and so on.
- Division 03 Concrete
- Division 04 Masonry
- Division 05 Metals
- Division 06 Wood, Plastics, and Composites
- Division 07 Thermal and Moisture Protection
Contains the most important information about the nature of the building enclosure system: insulation, roofing, water and air barriers, various schedules (tables) for thermal, flashing, fire protection, etc.
- Division 08 Openings
- Division 09 Finishes
- Division 10 Specialties
Contains information about louvers, vents, access flooring, toilet accessories, etc.

* Notes: There are various versions of Uniformat, with minor differences.
There are also "level 3" designations, where, for example, "G" Building sitework
is level 1; G10 site preparation
is level 2; and G1010 site clearing
is level 3.
The ultimate classification system, intended to classify everything in the built environment.
Conceived as 15 tables, each looking at the world from a different point of view. Various "legacy" documents have been included in, or as, these tables, so that building codes and Masterformat reappear, but within a larger framework. This is a compromise, to avoid duplication of existing classification schemes.
The tables are as follows:
|Facilities, constructed entities, and spaces|
|Table 11||function (construction entities)
||E.g., residences, hotels, etc.||legacy: IBC, etc.|
|Table 12||form (construction entities)
||E.g., bridges, high-rise buildings, etc.|| |
|Table 13||function (spaces)
||E.g., kitchens, offices, etc.|| |
|Table 14||form (spaces)
||E.g., courtyard, room, etc.|| |
|Table 21||elements, including designed elements
||E.g., exterior walls, etc.||legacy: Uniformat|
|Table 22||work results
||E.g., skills, trades, like cast-in-place concrete||legacy: Masterformat|
|| || |
|Table 31||phases (stages)
||E.g., conception, design, construction documents, etc.||legacy: IBC, etc.|
||E.g., designing, bidding, constructing|| |
||E.g., architecture, mechanical engineering|| |
|Table 34||organizational roles
||E.g., owner, architect|| |
||E.g., hammer, formwork, CAD software|| |
|Common characteristics of other tables|
||E.g., referenced standards, CAD files, periodicals|| |
|Table 41||materials (raw or refined)
||E.g., rocks, timber, glass|| |
|Table 49||properties (referring to a construction entity)
||E.g., color, width, fire resistance rating|| |
Note: Uniclass is British version of Omniclass.
