agrees that "traffic control was per- haps our biggest challenge. Frequently we had to stop work so as not to dis- turb the normal course of activities. Fortunately, these delays were built into our schedule." The Aquarium pro- vided extensive data on the effect of vibration and noise on the animals, which in turn dictated work flow. The entrance complex was also designed to house four new exhibit tanks and four ozone towers. Spaces in the original building were emptied and replaced by piping, mechanical pumps and heat exchangers. Because water must be treated to suit different aquatic environments, the main building harvests and filters sea water from Burrard Inlet. An ozone generator treats this water before it goes into a protein fractionator, which removes chemicals. The ozone is then degassed in the towers, and bio-media provide supplemental treatment (this same process will eventually be used for the outdoor pools). The upgrades are targeted to achieve a LEED Silver certification, therefore the entrance complex includes a rainwater harvesting system for non-potable use and radiant floor heating and cooling. It was also outfitted with a single-pipe hydraulic district energy system loop (about 1,100 feet of 12-inch diameter PVC pipe) connecting the heating and cooling plant, heat exchangers and cool- ing towers. Ultimately, this system will allow energy sharing amongst build- ings. PVC was chosen for its cost-effec- tiveness and to accommodate saltwater running through the heat exchangers. Thompson says of the construction materials chosen, "At all times we had durability in mind, hence the extensive use of zinc as well as aluminum for the curved walls, which were then coated with a special metallic paint that not only can withstand the elements but provides an iridescent two-tone effect." As of May, the first phase of upgrades was nearing completion and represents about 25 per cent of Musson's master plan. The next phase, the revamped Canada's Arctic display, is expected to break ground late next year. "Over half of the funding for this phase has already been raised and we're launching into full scale construction drawings," says Nightingale. The Aquarium president is satisfied by how the master plan is being real- ized. "Everyone is doing an outstand- ing job," he says. "What we've lacked for years is enough room for story-telling, which is essential to our success in the 21st century. Musson, PCL and many other professionals are providing us with exactly that." ■ ADDRESS 845 Avison Way, Vancouver, B.C.
