A. ALUMINIUM PARTITION

The purpose of this method statement is to describe the installation stages required in installing
gypsum board for drywall and wall partition while assuring quality, and health & safety compliance.

1. Work Description

Once the center-line of the partition path is marked on both the floor & ceiling the second stage begins by laying
down the channels on these marks It is important to ensure straight and accurate lines are maintained as well as
correct angles (90°, 120° & 135°).It is recommended to start with the ceiling track, and always at a corner, where
one places a corner channel and “grows” out of it with the necessary supplied floor mounting pieces placed in
the channels.

It is important to measure the exact distance necessary to cover the distance between two corner channels or
until a door-way passage which will remain “free” of a floor channel. Key Measurements should be noted when
doing so:

Channel clearance for doors begins 15 mm (19/32”) beyond the post center-line towards the door center. The
overall channel clearance for a door will always be 30 mm (13/16”) shorter than the module itself.

A channel segment that does not connect to corner channels (i.e. between doors, or extending towards two
partition ends) will always be 30 mm (13/16”) longer than the module itself.

When approaching an existing wall, the partition end profile (and off-module connection) will require 18 mm
(23/32”) gap between the channel and the wall.When approaching an off-module connection of two Modular
Partitions (known as a “T” condition) will leave a gap of 36 mm (17/16”) gap between both walls.When ceiling
channels are in place it is important to Secure them in a straight line using the channel alignment brackets.
Secure the channel ends in a way that will not damage ceiling or grid.

Positioning of floor channels will require the placement of the corner post. Please note that Posts and corner
posts are directional (the underside is not perforated to the end). Make sure the top side is placed into the
ceiling corner channels.When all corner posts are up and leveled ALL planes, the placement of the floor channels
takes place. Using the proper hardware appropriate for the floor type, all floor channels are placed and aligned
with the use of the same channel alignment brackets.In order to finish the channels towards existing walls (or in
off-module situations), one must install the relevant partition/wall interface unit (partition end or wall adapter).
These parts must be cut to size on site as they will form the support between floor & ceiling. Please ensure that
the IMT post adjacent to existing wall are level to gravity.

2. COMPLITING STRUCTURE

When all channels and corner posts are in place the rest of the structure can be completed.
Placing all posts in the correct estimated position is faster if the initial path marking included marking of the post
center-line. Placing posts in their position requires attention to the direction of the post (bottom part is not
perforated to the end). Only the NON perforated posts are placed into the floor channels.
Post will be aligned by the use of cross members. The cross members are universal and have no left/right or
top/bottom and are prefabricated to the required widths for easy and efficient assembly.

Placement of cross members must start at corners and progress outwards. Cross members are to be placed at
two levels. At minimum, at least the bottom cross member should be leveled consistently throughout the
project. The second member should be above the floor skin – optimally in the third hole on the post.

The third member should be installed below the ceiling skin. Cross members must be placed on both sides of the
partition. Cross members must also be placed across the bottom side of doorways to ensure proper alignment of
posts around the door-frame.

Towards other walls the end modules are never at the exact module width. These cross members will be
supplied to the site with only one cross member bracket attached and be oversized so they can be cut to size on
site.All cross members for each module need to be exactly the same to maintain post vertically.Once the cross
member is cut to the final size, any “loose” cross member brackets must be attached to it. Once all cross
members are in place, it will determine the exact width of the end modules (always solid).

Each end module will need to be measured individually. When end module width is defined, the end modules
must be shortened and finished with the proper edge in a local workshop.Universal connector holes will need to
be applied to the skins before they are hung on the posts.

3. CABLE MANAGEMENT

Once the frame is complete, the cable management contractor’s may follow the installation crews to install the
cables.If the contractors are aware of the skin positions (ie: position of glazing, etc…) wiring may be done with
the open frame.If glazing has been included in the project, all the glazed and utility skins that will not allow cable
management within their area should be temporarily installed to ensure nothing is wired incorrectly.

To speed up installation, skins may be installed on one side of the structure until the wire management and
electrical installation is complete. This requires appropriate scheduling between the trades and the IMT
installers to ensure the installation progresses smoothly.

The Modular Partition does not include any electrical wiring/outlets as part of a standard quote. Plug and play
options are available. Any electric style of system along with a qualified electrician (or Voice Data contractor)
may install his preferred choice. This lowers cost the overall cost and assists the end user in standardizing
infrastructure in the project.
Cabling may be routed:

3
COLORSPOT LIMITED.

Horizontally through the Square holes in the post.Vertically anywhere within the Partition inner space.All corner
connectors will allow vertical cable managementEven in an all glass partitions, limited cable management may
run through the open core of the Post. When routing cables vertically through a post, one may attach the cables
to the posts using cable ties. Outlets for electrics and/or data & communication may be mounted on or in any
solid skin and requires no special factory instruction. Standard installation (i.e. field cutting the location) does
not void any IMT warranty.Should the customer know in advance of manufacture dates, the outlet location and
hole configuration, prefabricated skins with the proper knockouts may be ordered as specials.

4. Installation of Doors
Once the door-frame is in place, it is easy to install a door. Solid doors (laminate or veneer) are directional and
may be left or right and are reversible if specified and quoted before production.

Installation Method: Confirm that the door is tagged for the office being worked on and fits the door-frame.

Attach the door hardware to the frame and door ensuring that the bottom hinge is resting on the floor to avoid
excessive load. Final leveling must allow the door lock to engage with the knockout in the door frame.

Glazed doors require additional considerations. Often they are ordered only once the door frames are in place –
this eliminates the varying height of the floor. Any glazed door above 220 cm will require a third hinge.

All doors that open towards a perpendicular wall must have stoppers. The stopper may vary in design and
function and are available as: Stopper installed in the floor.Stopper attached to wall or partition.

Examination / Preparations

Areas scheduled to receive suspended acoustic units must be inspected for unevenness, irregularities, and
wetness that might impair the quality of the work. Before commencing installation, access provisions must be
marked in terms of size and placement. Acoustical ceilings should not be put above any work, including
mechanical and electrical work, that requires inspection until all work is completed.Layouts must be completed
for inserts, clips, or other supports that will be put by other trades to support the acoustical ceiling.The
ceiling area must be measured/surveyed in order to determine the arrangement of acoustical units in order to
balance border widths at opposing sides of each ceiling.Less-than-half-width units at borders must be avoided,
and mirrored ceiling plans must be followed whenever practicable.Workers installing suspended ceiling cover

Process of Installation

The acoustic ceiling system must be installed in accordance with the manufacturer’s recommendations, project
specifications, and approved shop drawings.Suspension systems must be erected using just building members as
support. Hangers must be located no less than 150mm from each end and spaced no less than 1.2m apart along
each carrying channel or runner. The spacing of hangers, carrying channels, and runners must be matched with
the position of MEP fixtures, and hangers must splay where necessary to avoid obstacles.Additional supplement
framing and supports must be supplied if the ceiling is suspended below ducting, pipes, or other building
elements that are not appropriate for ceiling attachment.Hangers must be spaced no more than 1.2 inches apart
and fastened to the hanger inserts above. Carrying channel grid runners must be installed on 1.2m centers,
connected to hangers, and leveled. Cross-channel grids must be inserted between main channel grids, flush cut,
and secured to longitudinal channels.All exposed acoustical ceiling unit surfaces must be level and flush, with all
seams straight and true.Light fixtures and other components must be cut and fitted neatly. During installation,
replace any damaged tiles. Layout pattern in accordance with the approved plan’s reflected ceiling Tolerance
for ceiling suspension system leveling is 3.2mm 3.67m. Corners should be mitered precisely and firmly
connected. Suspended Ceiling Installation Instructions
