another flange of
30mm and a Web of 27 mm.
b) Intermediate channel: Channel Section of size 15x45x0.90 mm thick
c) Ceiling section: 0.5 mm thick having knurled web of 51.5 mm and 2

FINISHING
The boards shall be finished as per the manufacturer's recommendations.
All joints shall be carried out in three separate stages. Filling and tape
embedding, finishing and applying a surface treatment to even out differences
in surface texture and section.
Filling: All boards shall be securely and correctly attached, protruding
screws or nail heads should be driven home. Gaps greater than 3mm between
boards should be treated with jointing compound pressed firmly into the gap
so that it is completely filled. Jointing compound used for this purpose should
be stiffer than normal.
Tape Embedding: The joint fiber tape shall then pressed into the band of
jointing compound firmly embedded and free from trapped air bubbles, with
sufficient joints material under the tape to ensure good adhesion.
Immediately after the tape has been fixed a new layer of material is
applied over it, flush with the surface of the board. Before the material begins
to stiffen surplus material wiped from the edges of the joint by light sanding
without disturbing the main joint filling. Once the material has dried any slight
depressions in the surface can be filled again and projections cut back.
When the material has dried about 1 hour after application, a thin layer of
Gypboard jointing compound is applied in a broad band 200 mm wide. The
edges of this band should be immediately feathered out with a light sanding.
When the joint material has completely dried another application is made,
250 mm wide and sanded out as before
FINISH

5.8.5 Specification for laying and jointing sanitary pipes
5.8.5.1 Jointing
1. Make sure the spigot end and inside of socket is clean and the sealing
ring is placed evenly in the socket
2. During cutting of pipes, make sure that they are cut square. Chamfer
the end cut to angle of 15o
with a medium file.
3. A correct depth of entry of the spigot into the socket is required to allow
thermal movement. To achieve this, push spigot fully into the socket (remove
sealing ring at this time) and make a mark on the spigot. Withdraw the spigot
KMSCL: Tender for Construction of KCP outlet THQH, Karunagapally 61
by 10mm and mark the spigot with a bold line. This bold mark indicates the
correct depth of entry to allow the necessary expansion gap.
4. Apply rubber lubricant evenly on the chamfered spigot and the sealing
ring. Then insert the spigot into socket and pull out the pipe to allow 10mm
expansion gap.
5.8.5.2 Precautions
1. Avoid over tightening of door caps. Proper placement of rubber ring
should be confirmed before tightening
2. Avoid misalignment of vertical Pipe stacks and incorrect spacing of Pipe
clips.
3. Cutting of pipes should be straight, as diagonal cutting leads to
leakages.
4. All entry to main stacks should be protected with water seal trap,
wherever there is mixing of Soil & Waste lines.
5. Keep a gap of 10mm between all Pipes and Fittings to accommodate
thermal expansion and contraction of pipes for longer life of the system.
6. Horizontal lines within bathrooms should be cement encased and
tested before compacting of sunken floor to avoid any accidental damages.
5.8.5.3 Installation in walls/concrete
The wall/concrete slots should allow for a stress-free installation.
