4.0 WORK METHODLOGY
4.1 RIGID COUPLING INSTALLATION
1) Groove Pipe
Groove the pipe ends according to the manufacturer’s specification.
2) Check Pipe Ends
Pipe must be free from indentations, projections or roll marks on exterior
from the ends to the groove, to assure a leak tight seat fro the gasket.
Refer to Figure 1.
3) Check Gasket
Pipe must be free from indentations, projections or roll marks on exterior
from the ends to the groove, to assure a leak tight seat fro the gasket.
Refer to Figure 1.
4) Install Gasket
Place gasket over pipe ends, being sure gasket lip does not overhang pipe
end. Refer to Figure 3.
5) Join Pipe Ends
Align and bring 2 pipe ends together and slide gasket into position
centered between the grooves on each pipe. No portion of the gasket
should extend into the groove on either pipe. Refer to Figure 4.
6) Assemble Segments
Loosely assemble all segments leaving one nut and bolt off to allow for
“swing-over” feature. Refer to Figure 5.
7) Apply Housing
With 1 nut and 1 bolt removed, use the “swing-over” feature to position
housings over gasket and into the grooves on both pipes. Refer to Figure
6.
8) Insert Bolt
Insert the remaining bolt to allow easy tightening of the nut. Be sure track
head engages into housing recess. Refer to Figure 7.
9) Tighten Nuts

4.14 FIRE PROTECTION RISER PIPE INSTALLATION
PURPOSE
This method statement defines the methods and sequence to be carried out
for the installation of Fire Protection Riser Pipe to ensure they are in
compliance with contract requirements, technical specifications and quality
management.
SCOPE
This shall cover all the Fire Protection System, i.e. Sprinkler System, wet Riser
and Hose Reel System.
PROCEDURE
1) Check Location of Riser
- Confirm the location of riser based on approved / coordinated shop
drawings. - Check whether any opening through slabs (either box-up or pipe
sleeves) is provided. - Check the size of the opening. If the opening size is not sufficient or
opening is not provided, request permission for coring from the Main
Contractor. - Core opening once approval is obtained.

4) Install Riser Pipe - Confirm the location of riser based on approved / coordinated shop
drawings. - Lower down the pipe off any unwanted materials and rubbish from the
riser shaft. - If box opening is provided, slip a piece of pipe sleeve onto the pipe.
- Coupled the pipe with previously installed pipe with a flexible coupling.
(Please refer to Method Statement for the installation method of
flexible coupling). - Pull upwards the newly installed pipe using the chain block. This is to
allow pipe movement during the building shrinkage. - Align the pipe vertically with spirit level.
5) Install Riser Pipe Bracket - Once the pipe has been aligned, install the pipe bracket to support the
riser pipe. - If box opening is provided, install temporary bracket to the pipe.
- Cast the opening and ensure the pipe sleeves are installed prior to
casting. - Once the concrete has cured, dismantled the temporary bracket and
replace it with a permanent bracket.
6) Install Fire Barrier - Install Rock Wool into the gap between the riser pipe and the pipe
sleeve as per contract requirement. The Rock Wool will act as fire
barrier in the case of fire.

electrical riser.
ii) It consist of red color box complete with zone card termination
card.
iii) One RTTU can be linked to a maximum of 10 RFIS per set.
2) All the RFIS are to be terminated to the RTTU by 1 pair of PVC cable
1.5mm-sq each.
3) Wiring from the RTTU (Remote Telephone Terminal Unit) to the Main
Fireman Intercom Panel are:
a) 1 pair twisted and screened (5.4mm2) for data transmission.
b) 1 pair RVC cable (2.5mm2) for speech line.
c) 1 pair PVC cable (2.5mm2) for power supply.
TESTING & COMMISSIONING PROCEDURES
1) Minimum of two people are required for the testing. One stationed at the
Fireman Intercom Panel and the other at any chosen Remote Fireman
Intercom Station to actuate calls.
2) Check all indicating light on the Main Fireman Intercom panel console are
in good condition.
3) Calling from the master handset to remote intercom station;
a) Pick-up the master handset, key-in the remote station’s zone number
at the keypad. (Example : Zone 12. Press ‘Call’ Key, followed by ‘12’
and enter key).

CONDUIT INSTALLATION
1) MEASUREMENT / LOCATION OF G.I. CONDUIT AND MARKING OF CONDUIT ROUTE.
a) Site supervisor will study and counter check the proposed locations of the
conduit as shown on the shop drawing. Ensure proper coordination with the
Main Contractor and other trades to optimize the space allocation and proper
conduits management.
b) Site supervisor will measure the length of G.I. conduit required for installation
at site and instruct the workers to prepare these conduits. Installation will be
carried out in a planned and timely fashion so as not to delay works by other
trades.
c) For horizontal installation of conduits, straight lines are marked by using
string coated with white powder, tied to the nails at both ends. Ensures
appropriate string tension by plucking and releasing the string before

drawing the straight line. Repeat the steps above for vertical surface
installation.
2) FIXING OF SURFACE G.I. CONDUIT
a) After dismantling the strings and the nails, drill holes along the white lines.
Insert the drop-in anchor bolt into the holes before installing the rods.
b) Clip the G.I. conduits to the rods by using fasteners.
c) If necessary, the G.I. conduit will be cut to length required and threaded.
Threading will be process by stocks and dies. Rotate the stocks and dies two
and a half turns in a clockwise direction and the in a counter clockwise
direction, to clear away the accumulated swart. This will enable the tread to
be cut cleanly and efficiently without fear of stripping. Once completed, file
across the leading edge of the thread and reamer the inner periphery. This
prevents cable snagging on burred edges.
d) Conduit sockets complete with thread joint two length of conduits. In case of
crossing or ending or at ‘T’ junction area, cross-boxes, “Tee” boxes, “Trough”
boxed are normally used to link up conduit pipes.
e) As soon as the conduits are fixed, site supervisor will check and inspect the
site to ensure that installations are according to the shop drawings. A formal
request will be extended to the Resident Engineer.
3) STANDARD AND CERTIFICATION
a) Ensure that the capacities of trunkings and conduits provided are adequate
to cater all wirings with a minimum spare space of 40%.
4) METHOD OF FIXING OF CONCEALED G.I CONDUITS
a) Place the conduits between the two layers of slab rebar or behind the column
rebars from dropper to socket outlet points.
b) Ensure that conduits, inspection boxes, back boxes and all other accessories
used are rigidly secured to the rebar and all joints are firmly tightened before
concreting.
