GROOVED PIPING METHOD IMPROVES ACOUSTICS AND LOWERS CONSTRUCTION COST AT SINGAPORE'S ESPLANADE - THEATERS ON THE BAY
Concertgoers at Singapore's dramatic new Esplanade
Theaters On The Bay are unlikely to give much thought to the workings of the
climate control and fire protection systems buried deep in the building's
infrastructure. But an important contributing factor in the hall's high sound
quality is the specialized grooved-end piping supplied by Victaulic
Asia-Pacific. Rubber gaskets within the grooved-end joints significantly reduce
vibration and noise in the thousands of connections throughout the building.
One of the world's most acoustically advanced spaces, the 1,800 seat
Concert Hall is also insulated from the noise and vibration of nearby road,
subway and boat traffic by its unique design as an inner building floating
within an outside shell.
Installed cost savings of 10-30%
Improving sound quality was an important factor considered by the
mechanical and engineering contractors PWD Consultants Pte, Ltd., and MAE
Engineering, Ltd., in the selection. However, equally important were the
reliability and cost advantages of grooved end pipe joining as compared with
flanged, threaded or welded joints.
Because it is lighter in weight and
can be installed easily without skilled labor, the grooved-end method provides
total installed cost savings of 10-30 percent over other pipe coupling methods.
Grooved end piping requires fewer bolts than flanged connections. In addition,
it does not involve the open flame and attendant fire hazard of welding; or the
leakage problems commonly associated with threaded pipe. For convenience,
piping may be cut to length and grooved on the job site with simple tools.
Extensive Technical Support Services
The contractors
also took advantage of a full array of technical support offered by Victaulic.
The company advised in product selection and provided field installation
training for contractors and installers. Piping specialists were assigned to
the construction site for day-to-day assistance and to assure proper
installation. The large inventory carried by the company's Singapore
distributor was also a significant factor in the selection.
Eight lines
of 450mm and two lines of 350mm condenser water supply and return piping
connect the chiller pump room with cooling towers about 198 meters away. Rigid
couplings join the straight sections and special couplings that accommodate
deflection caused by pipe movement are installed at all bends. Victaulic
grooved end piping and fittings in 250-450 mm sizes connect the seven chiller
and pump systems. The sprinkler piping system uses Victaulic FireLock fittings,
a CAD-developed, hydrodynamic design which have a shorter center-to-end
dimension than standard fittings.
