Te Awamutu Intermediate
School is located in the township of Te Awamutu approximately 30km South
of Hamilton City in the North Island of New Zealand. The school has a
roll of between 400 and 500 students aged 11 to 13 years drawn from the
township and the surrounding rural district, and is the only Intermediate
school in the area. During 2003 the school commissioned a major project
to design and build a multipurpose Sports and Performing Arts Centre.
Adena provided theatre consultancy services, supplied stage lighting equipment,
and coordinated specialist theatre contractors to install the rigging. |

This photo shows
the spot bars at working height.
The spot bars and pulleys are finished in white powder-coat paint
to blend in with the ceiling. The control room and the winch enclosures
on each side of the control room can be seen at the top of the seating. |
|
|
|
Each spot bar is 12
metres long with 24 electrical outlets pre-wired in pairs to 12 dimmer
circuits. Adena
manufactured these spot bars in two six metre long sections that were
bolted together during installation on site. The electrics for the two
sections are linked together by short cable with a multi-pin connector. |
|
 |
Here the spot
bars are shown lowered to loading height. Each spot bar is suspended
by three wire ropes fitted with bridles to evenly spread the load
across the rigging. |
|
|
|
The ability to load
luminaires onto the spot bars from floor level enables students to safely
participate in the loading process. The spot bars can be operated at any
height within the winch range. This enables luminaires to be loaded and
the bar raised to about 2.5 metres where students can be taught focusing
procedures from the relative safety of a small step ladder. |

This photo
is taken from the winch location at the top of the seating
looking out across the court area with the spot bars in their
lowered position. |
|
|
Effective
management of the multicore electrical cables through ducting
above the ceiling ensures that the spot bar circuits do not
need to be unplugged to allow the spot bars to be lowered
or raised. |
|
|
|
 |
|
The multicore
electrical cable from each spot bar is terminated into a twelve
circuit junction box. Each junction box provides twelve tails
fitted with 3-pin plugs to enable the circuits to be plugged
into the dimmers as required for any production. Power is
provided to enable a second dimmer pack to be used when necessary. |
| |
|
The Theatrelight
Rack-Pack dimmer pack is bolted to wall brackets so that it
can be moved elsewhere when needed by simply unplugging the
pack and removing the bolts. This equipment is installed in
a lockable area of the building to prevent tampering and ensure
safety. |

This photo
shows one of the 500kg brake winches that are used to raise and
lower the spot bars. The winch enclosure is almost completed
in this photo. A safety notice is permanently posted adjacent
to each winch to remind operators of the maximum safe working
load and the safety procedures for operating the winches. |
| |
|
For safety
reasons students are NOT permitted to operate the winches.
A padlock is provided to lock the winch drum to its frame
to prevent unauthorised persons operating the winch. To prevent
tampering each winch is housed in a lockable enclosure. |
| |
|
The black
multicore electrical cable for the spot bar can be seen behind
the winch. A multi-pin connector, hidden by the head pulley
in this photo, connects the spot bar cable to the fixed wiring
in the building that completes the circuit to the dimmers. |

The auditorium lighting
consists of two separate systems to provide the range of flexibility required
for a multipurpose venue. The main system comprises of the overhead metal-halide
and fluorescent fixtures, all of which are controlled by appropriately
located switches. A second system, comprised of a number of wall mounted
incandescent fixtures is controlled by a Theatrelight Moodset dimmer unit.
The Moodset provides three preset levels and off with an automatic timed
fade between levels. This allows low level dimmable auditorium lighting
for theatrical performances and strong lighting for sporting activities.
