SOUNDBITE (English) Michael Arad, Architect of "Reflecting Absence" memorial: "What the water, one of the things I wanted the water in this design to do, is to really mark this continuing sense of absence. This notion that, you know, time moves forward, but this absence in so many people''s lives is persistent, it doesn''t go away. And these voids, even though water falls into them day in and day out, they never fill up. They always remain empty, and I thought that was very important to me." 4. Mid of cascading water 5.

So, we want to make sure that it always gives the same presentation in all types of temperature, in all types of weather, in all types of conditions. Our intention is to run it forever, never turn it off unless the weather is so absolutely against it if it''s twenty degrees below zero then we''ll have problems, but if the weather permits, we''ll never turn it off." 7.

SOUNDBITE (English) Michael Arad, Architect of "Reflecting Absence" memorial: "I want this site to do for people in future. I want for people to be able to come here, even if they come alone, to sense that they are not alone and facing this, to sense that they are part of a community that they''re there with other people, that they can find strength in each other to move forward." 10. Tilt down of waterfall STORYLINE: A mock-up of a memorial to be erected for the victims of September 11 was previewed on Friday to the media in Brooklyn. Standing three stories high, the waterfalls memorial is meant to evoke memories of the tragedy. Designed by architect Michael Arad, the mock-up of the cascades will eventually become the "Reflecting Absence" memorial, to be erected at ground zero in lower Manhattan. For more than three weeks, builders have been tinkering with the mechanics of the design to ensure it runs smoothly when it opens by the 10th anniversary of the 2001 attacks, testing the water flow and year-round heating. Arad saw his design, waterfalls which will empty into huge reflecting pools set above the spots where the Twin Towers once stood, tested for the first time on Friday. The waterfall-filled pools are the centrepiece of a memorial plaza that will take up half of the 16-acre site at ground zero. The pools will be surrounded by hundreds of sweetgum and white oak trees on a cobblestone plaza; a memorial museum currently being built below ground that will open about a year after the memorial. The foundation overseeing the memorial raised 350 (m) million US dollars privately to build it, while the government agency that owns ground zero is spending hundreds of (m) millions more on infrastructure at the site. Two of five planned skyscrapers and a multibillion-dollar transit hub are also under construction. The waterfall mock-up being tested in Brooklyn is 40 feet wide, representing a corner of two walls of one pool, a fraction of its actual 176-foot perimeter. The waterfalls will drop 30 feet and then another 16 feet into a centre void. Each will pump 26-thousand gallons of water per minute. Once the memorials open at ground zero visitors will look down on them from street level. A low wall covered by bronze panels inscribed with nearly three-thousand victims'' names will surround the pools. Both the waterfalls and the name panels will be backlit at night.
