TOUGHENED / TEMPERED) GLASS
Toughened glass shall be horizontally toughened on Tam glass produced by subjecting
ordinary (annealed) glass to heating followed by rapid surface cooling, which produces high
compression in the surface of the glass. To break this glass requires a force strong enough to
overcome the compression in the surface in addition to the normal breakage strength of
the original annealed glass. Toughened glass is up to five times as strong as ordinary glass in
resisting impact, and is also considerably more resistant to dramatic changes in temperature.
When it breaks, toughened glass fragments into small, comparatively harmless pieces. It
cannot therefore be cut to size and should not be drilled, surface worked or edge worked;
extra care must be taken to order the correct size required for glazing.
PREPARATION OF FRAMES AND GLASS
Before installation the contractor shall ensure that :
a.
b.
c.
d.
e.
f.
all glazing rebates are square, plumb and true in plane, clear, dry and dust free;
all frame adjustments are made prior to glazing;
all glass edges, are clean cut to exact sizes, allowing expansion tolerance as
recommended by the glass manufacturer;
all sashes shall be glazed in the closed position and shall not be opened until the
compound is set;
all materials are to be used in strict accordance with the manufacturer's
instructions.
glass shall not be forced into place;
COMPLETION
Upon the completion of the work all glass shall be thoroughly cleaned, paint or other marks
removed. Any cracked, scratched, chipped or other defective glass shall be removed and
replaced without cost to the owner. Any loose glass shall be set to the satisfaction of the
architect.
GLASS BREAKAGE
The contractor shall replace all broken, damaged & disfigured glass before acceptance of the
building, at no extra cost to the owner.
2.0 DUCO PAINT (BOQ Item no: 78)

proposed for duco paint is prepared by rubbing the wooden surface to be duco painted with
coarser sand paper. After minor repairs, the surface is again rubbed with sand paper no.100
and cleaned. Suitable duco paint putty is applied and the surface is left to dry. After
rubbing the surface with sand paper no.120 the surface is cleaned & kept dust free. Suitable
duco paint primer / surfacer is applied over the surface and left to dry. After rubbing the
surface with thinner using emery cloth and patti 2/3 times, surface is being made even and
smooth. 1st coat of duco paint is applied evenly with spray machine and the surface is
again left for drying 100%. Iind coat of duco paint is sprayed through machine after rubbing
and same above mentioned process is repeated till the third and final coat of duco paint.
Finally rubbing is done using thinner to give final finish.
3.0 VINERATEX RENDERING (BOQ Item no: 87)

TEST PLAN FOR UPS
Pre dispatch test and inspection:- The following test and inspections of the offered equipment
shall be carried out at bidder’s testing center or works place in the presence of customer’s
representative engineer and all the test reports and details of tests shall be sent to customer’s
office.
Test Name
Interconnection cable check & General requirements test
Light load
Checking of Auxiliary Devices
AC Input Failure
AC Input Return
Transfer
Full Load
UPS Efficiency
Rated Stored Energy Time (Battery Test)
Overload Capability
Restart
Audible Noise
Description & Aim of the Test:
Audible noise of a complete UPS may differ considerably from the values of individual functional
units. Room conditions, resonance and reflection will cause differences from calculated or
measured values.
Procedure:
The UPS is connected to full load.
b) The noise level of the UPS is measured at a distance of 5 feet from the front of the UPS
panel.
