VERTICAL INTELLIGENT ARCHITECTURE (V.I.A.) WALL
SYSTEM
1.0 EVALUATION SCOPE
Compliance with the following codes:
 2015, 2012, 2009 and 2006 International Building
®
Code (IBC)
Properties evaluated:
 Structural
 Surface-burning characteristics
2.0 USES
The V.I.A. Wall System is a relocatable, floor-to-ceiling,
nonload-bearing, non-fire-resistance-rated, interior wall
partition system. The system comprised of solid skins that
can be used where combustible construction is permitted.
The system using glass skins can be used where
noncombustible and combustible construction is permitted.
3.0 DESCRIPTION
3.1 General:
The wall system consists of steel structural members and
panel surfaces (skins). The structural members are
the following: posts and junctions, structural and
intermediate horizontals, ceiling tracks and floor tracks.
The construction of the skins are: glass, low-pressure
laminate (LPL), wood veneer, ceramic marker board,
painted steel and fabric-covered steel. When the V.I.A.
wall system is installed in accordance with this report and
the manufacturer’s published installation instructions, the
wall system has adequate strength to resist the 5 psf
2
(0.24 kN/m ) transverse load requirement specified in 2015
and 2012 IBC Section 1607.14 (2009 and 2006 IBC
Section 1607.13).
The V.I.A. wall system is recognized for wall heights up
to 144 inches (3658 mm) for module widths up to
A Subsidiary of the International Code Council ®
48 inches (1219 mm) with either posts or junction structural
members. The wall system is recognized for wall heights
up to 120 inches (3048 mm) for module widths up to
120 inches (3048 mm) with junctions. See Figure 1 of this
report for typical wall system.
3.2 Materials:
3.2.1 Ceiling Track: The function of the Ceiling Track is
to secure the V.I.A. wall to the ceiling. There are three
types of Ceiling Track: straight, corner fixed angle and
corner variable angle. The ceiling track features: U-Shaped
cross-section, powder coated, roll formed, commercial
quality (CRCQ) SAE/AISI 1008 – 1010 sheet steel, 0.043 –
0.047 inch (1.09 – 1.19 mm) base metal thickness,
complying with ASTM A1008/A1008M. Ceiling track comes
in 120 and 144-inch (3048 and 3658 mm) lengths.
3.2.2 Posts: The Posts provide vertical and lateral
support of the wall system, include threaded levelers for
height adjustment at the floor, and contain slots for hangon components. Posts can be specified to mount to the
Ceiling Track or Intermediate Horizontals. The backbone of
the Post assembly is a roll formed and spot-welded, steel
I-beam, rail. The rail is made from 0.057-0.061 inch (1.45 –
1.55 mm) thick, HSLAS-F Grade 50 steel. The steel
complies with ASTM A1008. Posts come in various heights
ranging from 15 to 144 inches (381 to 3658 mm).
3.2.3 Post Extension: When connecting a Post to the
ceiling track, the Post includes a Post Extension to
accommodate for height variation at the ceiling.
3.2.4 Structural Horizontals: The Structural Horizontals
provide structural connection from post to post at the top
and bottom of the wall. They are attached at the top and
bottom of vertical posts using frame connector brackets
and screws. The top Structural Horizontal interfaces with
the ceiling track. The bottom Structural Horizontal
interfaces with the floor track. Structural Horizontals have a
U-shaped cross-section and are made from 0.055 –
0.059 inch (1.4 – 1.5 mm) thick CRCQ, SAE/AISI 1008 –
1010 steel. The steel complies with ASTM A1008/A1008M.
Structural Horizontals come in various lengths from 6 to
120 inches (152 to 3048 mm).
3.2.5 Intermediate Horizontals: Intermediate Horizontals
attach to vertical Posts and/or partial-height Posts. They
are positioned between the floor and ceiling to support skin
or glass segmentation. Intermediate Horizontals have a
U-shaped cross-section and are made from 0.055 –
0.059 inch (1.4 – 1.5 mm) thick, CRCQ, SAE/AISI 1008 –
1010 steel. The steel complies with ASTM A1008/A1008M.
Intermediate Horizontals come in various lengths from 6 to
120 inches (152 to 3048 mm).

accommodate variations at the base of the wall. It provides
visual and acoustic separation at the floor. Springs are
inserted between the Floor Track and Structural
Horizontals to ensure continuous contact of the Floor Track
with the floor. The track is roll formed of HSLA cold rolled
steel, 0.043 – 0.051 inch (1.09 – 1.3 mm) thick, and

4.0 INSTALLATION
4.1 General: Floor and ceiling tracks of the wall system
must be mechanically attached to ceilings and floors to the
satisfaction of the code official. A structural analysis to
ESR-3378 | Most Widely Accepted and Trusted
determine the adequacy of the ceiling grid to support the
lateral load imposed by the wall system in accordance with
Section 13.5 of ASCE 7 (as referenced in Section 1613 of
the applicable IBC) must be provided to the code official.
Glass in glazed partitions must be designed and installed
in accordance with Section 13.5.9 of ASCE 7 (as
referenced in Section 1613 of the applicable IBC).
4.2 Frame Assembly:
An initial Vertical Post assembly or Junction is positioned
beneath the ceiling track and the leveler aligned with the
floor track. The post extension must be fully extended into
the ceiling track. There must not be a gap between the top
of the ceiling track and the top of the post extension. The
Post or Junction is then plumbed. Additional Vertical Post
or Junctions are positioned at predetermined distance from
the initial Vertical Post or Junction and installed in a similar
manner. Structural Horizontals are attached between the
Vertical Posts or Junctions at the top and bottom of the
wall using supplied Frame Connector Brackets and
screws. The frame assembly is then leveled. Intermediate
Horizontals are attached where needed between Post or
Junctions with supplied Frame Connector Brackets and
screws. The maximum spacing of the posts or junctions
must be in accordance with Table 1.
4.3 Solid Skins:
All solid skins (i.e. LPL, Painted, Fabric and Ceramic) are
provided with a combination of brackets and latches used
to connect the skins with the structural framework.
Additional metal trim pieces are installed where required.
4.4 Glass Skins:
Brackets are attached to the structural framework
(Structural Horizontals, Intermediate Horizontals, Posts
and Junctions) at specified locations with supplied screws.
The first side glass frame is placed in the pre-assembled
frame opening and attached with screws to the brackets.
The second side trim frame or glass frame is then inserted
from the opposite side. Latches on the brackets retain the
second side frame. Highly-visible lock wires on the
brackets are then rotated to a fully-locked state, securing
the opposite side.
