Standard "Quick-Ship" Modular Offices

Installation Instructions
Important:
We advise a thorough reading of these instructions before beginning installation.
Introduction
Instructions should be read thoroughly and cross-referenced with your job drawings prior to commencing
installation.

Standard "Quick-Ship" Modular Offices are manufactured from high quality materials with care taken in handling
and packing at the factory. Please inspect your materials and count them to make sure that damage or loss has not
occurred in transit. Please notify us promptly if you experience any problems. Review the accompanying Bill of
Materials and parts drawings to familiarize yourself with the components of the system. Care must be exercised in
handling these materials. The framing parts are made from painted steel and anodized aluminum. The material,
while strong and durable, will scratch, bend and/or mar. Normal care in erection will result in a finished product of
which we both will be proud.

Unpacking, Inspection & Inventory
The Modular Office wall system is packaged in the factory in a manner to protect each part during normal shipping
and handling. It is recommended that the original packaging remain intact as much as possible until the individual
parts are needed. All extrusion components are typically packaged in boxes. Panels are shipped with a foam
interleaf between panels.

As the skids are received at the job-site, they should be placed in a location near the installation area, where they
will not become an obstacle, or require to be moved at a later time. The skids should then be opened, however
leaving the internal packaging unchanged. Pieces can be removed on an as needed basis and the packaging
discarded then. At this time the components should be visually inspected for obvious damage and an inventory
taken to confirm that all parts are received as expected. Notify us immediately of any discrepancies.
Fasteners Not Provided
The attachment hardware for the floor track to the flooring and wall starters to existing structures are not included
due to installer preferences, local codes, and varying flooring and ceiling systems.

The following are recommendations:
     • Concrete floor: powder actuated fasteners: heavy duty dome head nail – type DS 1-1/4" long
     • Wood floor: 1/4" x 1" lag bolt
     • Steel floor: #14 x 1" sheet metal screws
     • Drywall: 1/4" toggle bolts, drywall or wood screws
Installer Tip!
To save time, mark the centerlines of all the studs on the floor in front of the floor track. This will assist you in
maintaining the centerlines shown on the drawings.
Floor Track Installation
Step 1 Locate the first wall and strike a chalk line
on the floor. This line is the outside edge of your
floor track.

Step 2 Lay out the floor track per floor plan
drawings. Cut floor track length as noted by F.T.
dimensions on the drawing. Use metal snips to cut
the floor track lengths. Note: Use the 3 - 4 - 5
triangle method or a carpenter's square to confirm
90° corners. (Detail A)

Step 3
Mark wiring stud centerlines & door
openings per plans. (Note: It is imperative that
stud centerlines be maintained.)

Step 4
Notch corner locations (Detail B) to allow
ends to lap each other.

Pre-Assemble Stud Posts
The holes of a stud hat have an offset pattern that allows two identical hats to
be secured together by rotating one of the hat sections. This alignment will
offset the holes, allowing the standard #10-16 x 3/4" Tek 2 screw to use a pre-punched hole on one hat and to tap through the opposing hat. (Detail D)

Assemble stud posts. Leave out the cover strips until Step #8 of Electrical
Section.

Screw the stud sections together leaving the sections loose enough to install
the panel.

Detail D
The holes of a Series 300 stud hat are prepunched on both sides of the raceway at 12" o.c. Assemble stud assembly by inserting Part A into Part B. Using a #10-16 x 3/4" Tek 2 screw fasten the two parts together using a prepunched hole on Part A to tap through the opposing Part B.
Wall Erection
Wall panels are fabricated and ready to install. Standard wall panels are 44-7/8" wide and are interchangeable with
other full panels, windows and door panels. Special width filler panels (F.P.) are labeled on floor plan.

Step 6 Check the floor for level. In extreme cases (out of level by 1/2" or more) select the high corner as your
starting point. If possible, leave the door panel to be installed last. Shimming may be necessary if floor surface is
not very level.

Step 7 Begin wall installation by inserting a corner post into the floor track (Detail E). Note: the corner post is
inside both the vertical legs of the floor track. The corner post should be loosely assembled using Phillip's flat head
1/4"-14 x 3/4" screws to allow install of panel.
Tighten the corner post screws and install vinyl corner inserts (Detail G).
Begin wall installation by inserting a corner post into the floor track (Detail E). Install the two adjacent corner wall panels into the floor track and slide gently into corner post (Detail F).

Install pre-assembled studs next to each panel. Check centerline dimension of stud to corner post from your floor plan. Tighten screws after panel is in place (Detail H).
Load-Bearing Office
Install a 10 gauge bearing plate inside the floor track below
each stud and corner. Use 3-3/16" x 5" plate for studs and
4-1/2" x 4-1/2" notched plate for corners.
Assemble mitered cornice mold corner assembly (Detail I).
Step 10 Assemble mitered
cornice mold corner assembly
(Detail I). Each standard corner includes two short pieces of
cornice mold with one end
mitered. These special pieces
will be used to make your
cornice mold corners. If corner
to stud dimensions is less than
50-1/4", field cut the cornice
mold so that the end not mitered falls on the centerline of the
stud. Secure cornice mold
corners to the interior side of
the corner post w/ #10-16 x 3/4"
Tek 3 screws.


Step 11
Insert next panel into
floor track; slide into stud and
tighten screw. (Note: Do not
over tighten screws). Continue toward next corner. Check each panel for plumb (Detail J).

Step 18 Insert the upper window panel. (Detail L)

Step 19 Slide on the adjacent stud and proceed with the next panel.

Note: To prevent breakage, we recommend the window be moved only in an upright position with the bottom
supported.

For a neat job, make certain that the window frames are inserted completely into the studs and the sill heights
align. If the wall consists of many window units it is imperative the windows be inserted all the way into the studs
and you check your centerline dimension of your studs to make sure they match the drawing; otherwise the wall
will grow in length and the last unit will not fit into the corner.
Vinyl Base
Step 20 The screw on vinyl base should be cut to fit for the interior and exterior of the room. Lift cover flap and
secure to wall with #10-16 x 5/8" pan head screws at 24" centers. Push the cover strip in, to lock in place, and
cover screw heads. Pre-formed exterior corners are supplied for the outside corners only. (Detail N)

Double Door Installation
Walls should be secure at this point. Check on this before installing door.

The double door assembly is shipped knocked down and is not pre-hung in a panel. Framing for the door opening
includes steel tubes for 3" walls and steel channels for 1-9/16", 4-5/8" and 6" walls. The door should be installed
during the wall installation. The steel assembly framing should be in place with the remainder of the wall. All studs
should be secured to the cornice mold before adjusting the frame. Note: The material sizes indicated in the
following steps are for a 6'-0" x 7'-0" double door in an 8'-0" wall system. Sizes will vary for other door sizes and
wall heights. Refer to drawings.

Assure that studs on each side of the door are plumb and located properly according to the layout. The distance
between studs should be 76". (Detail V)

Install 84-7/8" vertical tubes or channels into each stud. (Detail X) Note: Channels are installed with the open side towards the stud.

Dust Cover Installation
The dust cover consists of metal decking and support beams, as required. The standard decking is 22 gauge, 1-1/2"
type "B" deck, and is required to make the office walls freestanding. The decking has a modified "V" roll form
design. As such, it will grow or shrink in width during installation. Care should be exercised to control the
dimensions while installing. All Fire & Sound buildings come with a rubber deck closure to fill the corrugation
openings between deck and building.
Install the dust cover by placing the first piece of deck at one end of the office, resting on the cornice mold. Follow dust cover layout on building plans. Note: Unless the office has been specifically designed to have a storage roof, it is not intended to hold the weight of a person or storage.
Prior to screwing the dust cover down, insert the rubber deck closure by tacking it between the dust cover and the top of the cornice mold. (Detail 7)

    3/4" Tek 3 screws at 18" o.c. along the seams and
    with #12-24 x 1-1/4" Tek 5 screws in every other
    valley. (Detail 6)

4) Make a mark on the cornice mold to locate the
    placement of the next section of the decking. This
    dimension will vary between 35-3/8" and 36-1/4".

5) Place the second piece of decking next to the first
    piece with the edge overlapping the return lip of the
    first piece. Note: Be sure to secure each piece.

6) Continue installing decking across the room as
    instructed above to complete. (Detail 8) Overlapping
    dust cover sections may be necessary. (Detail 9)
    Please refer to job drawings sent with project.
Non-Load Bearing Beams
Place support beams above the walls. Beams must be supported by wall studs or steel columns at ends. Follow layout drawing for proper beam placement.

Step 1 Secure ends of beam with #10-16 x 1-1/2" Tek 3 screws into cornice mold at wall. (Detail 10)

Step 2 Fasten roof deck to the beam with #12-14 x 1-1/4" Tek 5 screws at 12" o.c. To complete the deck installation, refer to dust cover installation on previous page.

Step 3 Attach conduit beam braces to the beam top flange and dust cover.
Secure ends of beam with #10-16 x 1-1/2" Tek 3 screws into cornice mold at wall. (Detail 10) If installing a bean onto a column, follow steps 1-3 when securing top plate of columns. (Detail 11)

Electrical wiring should be done by a qualified electrician.
Electrical
1) Install handy boxes into studs at desired locations with a #10-16 x 3/4"
    Tek 3 screw. Fasten through the back of the box (Detail 12) Typical
    locations are 12"-18" above the floor for duplex outlets and 48" to 54"
    AFF for switches and single outlets.

2) Cut conduit as needed. Conduit should terminate just above ceiling
    level.

3) Install stud cover plates by cutting to size above and below each handy
    box location. Cover plates should also terminate just above the ceiling
    to allow for wiring across the ceiling.

4) If installing a bean onto a column, follow steps 1-3 when securing top
    plate of columns. (Detail 11)
Detail 12
Acoustical Ceiling Installation
Determine the required finished ceiling height for the room. For ease of installation and proper light fixture
clearance, the ceiling should be a minimum of 6" below the underside of the deck (6-1/2" if an exhaust fan will be
installed). Most building codes require a minimum clearance of 7'-6" from the floor to ceiling.

1) Snap a chalk line 1" above the required ceiling height around the perimeter of the room. This line should be
    checked for level before snapping the string. (Detail 14).

2) Cut wall mold as required and position so that top of angle is even with the chalk line. Secure the wall angle to
    studs and corners with #10-16x3/4" tek 3 screws. Proceed around the room. Wall mold may be overlapped or
    miter cut at corner joints.

3) Mark the location of main runners by putting marks above the wall mold. Tie a string around the wall mold and
    stretch it across the room near the position of the main runner. This will provide a reference line to install hanger
    straps and wires.
4) Attach wire hanger straps to the bottom of the dust
    cover at 4' o.c. Along each main runner. (Detail 15)
    Make certain that a hanger wire is located at each
    corner where a lay-in light fixture will be. Cut hanger
    wire as needed, usually allowing an additional 6" at
    each end to twist in place. Install wire through the
    hanger strap; bending wire back down and wrapping     tightly 3-4 twists. (Detail 16)
Attach wire hanger straps to the bottom of the dust cover at 4' o.c. along each main runner. (Detail 15)

Detail 16
Detail 15
Detail 14
The ceiling grid consists of two major components, 12' main runners and 4' cross tees. (Detail 17) The main
runners typically run the longer length of the room. Closely follow the layout drawing provided to assure easy
installation and proper material quantities.

5) Install 12' main runners at locations shown on drawing using hanger wire provided. Be certain that 4' cross tee
    anchor points correspond to the ceiling plan. Allow the main runner to fully rest on the wall mold.

6) The ceiling wire may then be attached to the main runner. Be sure to wrap the wire around itself at least 3 times.
    (Detail 16) Care should be taken to install the main runner straight and level. Continue until all main runners are
    installed.

7) Install cross tees at points indicated on the drawings by inserting tabs into anchor points. Trim pieces at wall, as
     required, for tee to rest fully on wall mold. To strengthen the grid the tees may be secured to the wall mold with
     pop-rivets (not supplied). Intersections of cross tees and main runner must form a 90-degree corner. (Detail 18)

8) Place light fixtures into grid at locations indicated on drawing. Make certain that a hanger wire is located at each
    corner where a lay-in light fixture will be.

9) Cutting ceiling panels may be accomplished with the panels facing up using a saw or a very sharp fiberboard
    knife. Measure and cut each of the border panels individually.

10) Lay-in panels are installed by carefully tilting the panel to fit through grid opening then resting the panel on
    cross tee and main runner flanges. Exercise care when handling ceiling panels to avoid marring the surface.
    Handle edges of panels, keeping fingers off the finished side of the panel as much as possible. Clean hands are
    necessary for a clean job. It may be necessary to use the left over portion of the tile for other cut pieces.
Install cross tees at points indicated on the drawings by inserting tabs into anchor points. Trim pieces at wall, as required, for tee to rest fully on wall mold.
