• Walk-Through

2
Introduction
How many alternative designs are considered for
any given construction detail? Millions? Doe
s that make developing a library of the
alternatives a hopelessly large task? Not if
it is done efficiently. Think about it

3
Introduction
If you had 10 marbles each one a different
color how many different arrangements could you
make? The answer is 3,628,800

4
Introduction
If instead, you had 50 subassemblies each
fulfilling a different set of design
criteria how many different details could you
make? The answer is 30,414,093,201,713,375
,000,000,000,000,000, 000,000,000,000,000,000,000
,000,000,000,000 Approximately. Think of what
you could do with 300. Or 1,000.

5
Introduction
While this analogy isnt perfect, the point is
close enough you need only a small number of
subassemblies in a system in order to potentially
have an almost unlimited number of details. The
key is having the right set of subassemblies, and
organizing them well. This concept is the heart
of DetaiLogic

6
Introduction
DetaiLogic is software. It helps users design
construction details and specifications with a
limited number of subassemblies that are
archetypical and meaningfully organized,
compiling them into the most appropriate
combinations.

7
Introduction

• The subassemblies are arranged into four sets
• Surfaces That enclose the other subassemblies
• Supports That hold the other subassemblies in
  place
• Separations That keep inside in and outside out
• Systems That carry utilities such as
  electricity, water, conditioned air, and waste.

8
Mechanism
How does it work?

9
Mechanism
DetaiLogic is question-driven (think of
TurboTax). It asks users to either pick
subassembly archetypes from its lists or to
identify the performance criteria that the
completed detail will have to fulfill. Users can
make selections at any of five levels.

10
Mechanism

• Where performance criteria are identified, they
  are organized using a standard list.
• Criteria can be stated in subjective or objective
  terms.
• Users can leave low-priority criteria blank.
  DetaiLogic considers stated criteria, ranked as
  requested, and non-stated criteria when needed to
  avoid incompatibilities.
• The list is extensive and expandable.

11
Mechanism
Once input is provided, DetaiLogic takes over.
It proposes subassemblies and materials for any
not chosen by the user. Then it compiles them
into connections and the connections into
complete details. It also compiles the
corresponding specification sections.


12
Mechanism
It reports the combined performance achieved by
the final combinations. Finally, once all of
DetaiLogics recommendations have been accepted,
it exports editable CAD details and
specifications. Users can then customize them
further and paste them into their contract
documents.

13
Underlying Order
Underlying it all is a taxonomy, a classification
system for all information related to
architectural detailing. Every material,
assembly, subassembly, style of detailing, form
of documentation and more is assigned a numeric
tag. This chart shows just the first
few levels of depth within the expandable
DetaiLogic taxonomy. NOTE The system works
even when its existence is completely hidden from
the user.

14
Populating DetaiLogic
As with the performance criteria, data in the
DetaiLogic library is prepared using standard
formats to insure compatibility. The examples
here show two different options for a Support
Subassembly.
Notice how corresponding details use the same
format, so are easily interchanged.

15
Populating DetaiLogic
Notice also how each detail shows only one
subas-sembly. Others are dotted, abstractly. Once
all needed subassemblies are selected, details
corresponding to each can be compiled into a
single drawing. Notes in italic are there as
hints to the user, and do not print.

16
Updating DetaiLogic
As the industry moves from 2D drawings to 3D
interoperable models, DetaiLogic will be ready
due to its data-independent organizational
structure.
In addition, the same bar code approach that
makes retail inventory systems work can now works
for the design of architectural details and
specifications.

• Facades are generally the most visible
  architectural form, articulated to express
  presence, and detailed to control interior
  environment. They must be buildable, and once
  built, last for years under unrelenting
  meteorological conditions. To maintain both a
  human relationship and construction feasibility,
  facades are articulated with architectural
  elements, establishing rhythms and scale.
• ? Kahn Elegantly articulating a façade at the
  Kimball Museum with a repeated barrel vault roof
  and reveals in the façade.
• Adler Sullivan Establishing bays in multiple
  layers to organize a façade. ?
• Implications for Detailing
• Position and distance of viewer Scale is
  relative to distance and foreshortening, so
  knowing the distances and positions of potential
  viewers is critical. Large buildings can easily
  be of a scale that is beyond human perception
  and interest. Articulation of facades can be
  varied from bottom to top as distance from viewer
  changes.
• Aesthetics The proportion between solids and
  voids, the scale of the bays, the number of
  materials used and the degree of articulation all
  strongly affect a façades look and its
  detailing. Floor planes, column lines, and
  partition spacing form a baseline for
  articulation connections can provide starting
  points for elaboration.
• Materiality Façade design often follows a
  natural spacing suggested by the expansion and
  contraction of façade materials, or by the limits
  of construction and transporting materials to the
  site.
• Structural impact Materials have to span from
  one structural element to another. Smaller
  architectural bays supported by larger structural
  spans may require intermediate structural
  elements.
• Egress Bedrooms within 75 of the ground are
  required to have operable windows, unless
  designed to the high rise code.
• Window washing equipment, for facades beyond the
  reach of ladders, must be accommodated with
  tie-ons and rails.
