Group 6G - Curtain Wall Manual, Part IV: Responsibilities of the Architect Related to Installation Flashcards
Aluminum curtain walls are:
Usually built in place, on the job
Typically a factory-made product, manufactured to close tolerances
Manufactured to flexible tolerances to accommodate field conditions
Installed on a field-built structure of higher precision and dimensional accuracy.
Typically a factory-made product, manufactured to close tolerances
An Architect should ____ to ensure that the curtain wall is properly installed.
verify all building dimensions prior to approving shop drawings
provide clear and comprehensive drawings
be the sole input on the installation and system design
provide carefully considered specifications
provide on site supervision of the installation
provide clear and comprehensive drawings
provide carefully considered specifications
The _____ curtain wall system offers the greatest flexibility in installation.
Storefronts
Stick Curtain Wall Systems
Unitized Curtain Walls
Window Wall Systems
Stick Curtain Wall Systems
Pre-assembled frame units with interlocking edges ________placed sequentially around a building floor before the next floor of units can be installed.
don’t require that frames are
must usually be
differ from unitized curtain walls which must be
don’t allow frames to be
must usually be
In the case of a curtain wall installed outside of the
building frame, rather than between floor slabs or
between masonry columns or piers, work:
may proceed both horizontally and vertically over
the face of the building at the same time
cannot proceed sequentially around a building floor.
must proceed progressively, rather than in several locations at the same time.
must proceed progressively, rather than in several locations at the same time.
_________usually permits faster curtain wall erection, resulting in less time to complete the entire installation, because the building process can proceed in stages.
Steel frame construction
A reinforced concrete frame building
Allowing more floors to be completed before the wall installation begins
Starting from both ends of the building and working toward the middle
Steel frame construction
and, for concrete:
Allowing more floors to be completed before the wall installation begins
The type of building structure used ________the scheduling of the wall installation.
Always defines
determines to some extent
is irrelevant to
must work around
determines to some extent
One of the most serious problems continually being
encountered in the field is the lack of:
frame materials available
adequate structural support for the frame
adequate attachment details
labor availability
supervision
adequate clearance for proper wall installation
snacks and naps
adequate clearance for proper wall installation
________dictate the location and alignment of the curtain wall.
Actual dimensions
Theoretical dimensions on the plans
Standard frame unit sizes
Actual dimensions
Aluminum curtain walls are designed to accommodate
reasonable variations, per tolerances established by:
American Concrete Institute
Prestresssed Conrete Institute (PCI) code
AAMA SFM-1-14
ASCE-7
American Institute of Steel Construction (AISC)
American Concrete Institute
Prestresssed Conrete Institute (PCI) code

To help assure a ‘plumb and true’ installation the Architect should:
Clearly define the maximum tolerances to be permitted in the building frame alignment
Define the intended locations of all surfaces affecting curtain wall alignment
Specify a stick-frame curtain wall installation.
Design a steel-framed building
Verify that the general contractor frequently checks and documents that the permitted tolerances are being held.

carefully installed by floor, starting at ground level
carefully installed in vertical columns
carefully installed with due regard to it’s design features
carefully securing all bolts with stainless steel nuts.
carefully installed with due regard to it’s design features
