Survey and mark out the exact location of all boxes in

a ceiling or wall conduits follow all the
distances, height and marking given in the approved
layout & detail drawings.

Ensure that the work site locations have been released

b and ready for safe works execution
especially the wall surface where boxes and conduits
are to be installed

Rigid heavy duty PVC conduits shall be used for Lighting

c and power systems. Low current
systems, above false ceilings and embedded areas as
Per Project Specifications and approved
shop Drawings
Expansion ring. PVC boxes, adopters, male bushes,
d locking nuts shall be utilized as per
approved shop drawings
Expansion coupler shall be utilized at locations where
e PVC Conduits are crossing construction
expansion joints
 Connect conduits terminating in switchgear, fuse
f boards, trunking, adaptable boxes or other non-
spouted enclosure with smooth bore male PVC bushing
and sockets
g Ensure that conduit connections are tight and fixed
rigid
h The outlets shall not run more than the permissible
numbers of conduits to any surface wall outlet
The exposed conduit work is to be installed so as not to
i interfere with ceiling inserts, lights or
ventilation ducts or outlets
j Use approved hot bent method to bend the PVC
conduit if conduit over 25 mm and below
k 25 diameters use cold bent by bending spring
l The conduits on walls are to be run neatly, horizontally
or vertically
Provide pulling wire (GI wire or equivalent strength
m cord) in each conduit. Secure the wire inside the box or
at end of conduits and covered.
Any changes in the routing of conduits shall be mark in
n the as built drawing & All installed conduits to be
protected until the next activity and final handover
6 INSTALLATION OF STEEL CONDUIT (RGS AND HEAVY GAUGE RIGID STEEL):

Survey and mark out the exact location of all boxes in

a ceiling or wall (Concealed) follow all the
distances, height and marking given in the approved
Shop Drawing and IFC drawing

After verifying the exact location and provided all the

b necessary mark out, start installing the
box by drilling in the concrete wall, column or ceiling
and fixed the box

c After completing the installation of the box, start fixing

the conduits. Conduit shall be securely
fastened in wall

Where a conduit is placed in a sheet metal enclosure or

d outlet boxes it shall be securely fixed
using Locknuts arrangement

Ensure that conduit threads are properly cut. Conduit

shall be cut using a saw or a roll cutter
e (pipe cutter). Care should be taken to ensure a straight
cut. After cutting end conduit fittings are to be cleand.
Cut end are to be reamed to remove burrns and shurp
edges
 Thread less couplings and connector used with conduit
f shall be made tight. Where installed in
locations, they shall be the rain tight type. Thread less
or screw type coupling and connectors
shall not be used on threaded conduit ends unless
listed for the purpose.
Threads of plugs, junction boxes and other fittings shall
g be lightly lubricated with rust
preventive grease before assembly
Provide pulling wire (Gl wire or equivalent strength
h cord) in each conduit. Secure the wire
inside the box or at end of conduits and covered
i Remaining threads on galvanized steel conduits are to
be filled with touch up paint
j Any changes in the routing of conduits shall be mark in
the as built drawing

7 INSTALLATION OF EXPOSED CONDUITS (EMT, RGS HEAVY GAUGE & PVC

COATED)

Survey and mark out the exact location of all boxes in

a ceiling or wall (exposed conduits
installation). Follow all the distances, height and
marking as per approved shop drawing and
IFC's.
Exposed RGS conduits shall be installed in mechanical
b rooms and outdoor installation.
EMT conduits shall be used above false ceiling

Expansion arrangement shall be made for RGS & EMT

conduits when crossing expansion joints. Ensure that
c work site locations have been released and ready for
safe works execution especially the wall surface where
boxes and conduits are to be installed. (wall shall be
painted
minimum first coat of approved paint before installing
the boxes and conduits).

After verifying the exact location and provided all the

d necessary mark out, start installing the
box by drilling in the concrete wall, column, or ceiling
and fixed the box using anchor bolt ( Plastic & metal
anchore)

Electrical Metallic Tubing (EMT) shall be used for

e exposed fixings and above false ceiling
wherever applicable as per the project Specifications
and approved Shop drawings

f Rigid heavy gauge steel conduit is used for all exposed

installation such as mechanical,
electrical equipment rooms and all hazardous area
 Ensure that the boxes are Inspected fort alignment,
g height, distances, flatness after fixing and bolts/screw
are securely fastened.
The conduits on walls are to be run neatly, horizontally
or vertically as may be required as per
the approved Shop drawings.

After installation of the boxes, fix conduits. Conduit

h shall be securely fastened in ceiling, or wall using
approved double hole clamp not exceeding the
distance specified in project
specifications

Where a conduit enters a box, fitting, or other

i enclosure, a bushing & locknut shall be provided
to protect the wire from abrasion unless the design of
the box, fitting, or enclosure is such as
to afford equivalent protection

The outlets do not run more than the permissible

j numbers of conduits to any surface wall
outlet. The exposed conduit work is to be installed so
as not to interfere with ceiling inserts, lights or
ventilation ducts or outlets

Thread less couplings and connector used with conduit

shall be made tight. Where installed in
k wet locations, they shall be the rain tight type. Thread
less or screw type couplings and
connectors shall not be used on threaded conduit ends
unless listed for the purpose. Ensure that conduit
connections are wrench tight.

Provide pulling wire (Gl wire or equivalent strength

cord) in each conduit. Secure the wire
inside the box or at end of conduits and covered.
l Channel erector system components (Unit
strut or similar) used to support conduits, cable trays,
enclosures, lighting fixtures and other
electrical equipment shall be made hot-dip galvanized
(preferably).
All field cuts unit-strut shall be touch up with approved
paint.
m Any changes in the routing of conduits shall be mark in
the as built drawing
8 INSTALLATION OF EMBEDDED CONDUIT IN SLAB AND WALLS (PVC, RGS):
 PVC conduits in reinforced concrete structures are
generally to be installed after placing
a reinforcement and before concreting, using the steel
boxes and fittings such as coupling.
adapters with locknuts, and PVC solvent. Sizes of
conduits and boxes to be installed as per
approved shop drawings.

PVC Conduits shall only install embedded in concrete

b slab or block work, exposed PVC conduits works is not
permitted. Survey and marks out the exact location of
all boxes, conduits in the slab and walls.

Ensure the coupling of conduit and termination into

spouted fittings is to be made watertight
c and permanent using special cement.
