Victoria-based Lombard Pre-Cast Inc. made some of the pre-cast catch basins and manholes. “They were engi-neered and designed to suit the heavi-er load of airport traffic. We also used heavy-duty frame and grates, which needed to be Transport Canada-rated,” Sedgwick says. The excavated areas were back-filled with three-inch (75 millimetres) crushed road base on sub-base material and some three-quarter to one-inch (19-25 millimetres) crushed rock road base for the base material. “On average we had a 400-millimetre lift of the 75-millimetre crushed gravel subbase, 400-millimetres of the rock crushed granular base, and a 200-millimetre lift of asphalt paving,” Sedgwick says, noting that a collector road would require a 75-millimetre lift of as-phalt and a highway 100 millimetres. G&E subcontracted Victoria-based Island Asphalt Company to lay 6,600 tonnes of asphalt. Equipment used in-cluded a AP1055F Caterpillar Paver, a PM200 Caterpillar Milling Machine with an ounce of dirt stopped 1000 tons of rock? Regal listens – we keep you moving.

Where planes park, surfaces with higher load resistance than asphalt are required. G&E built 141 6-metre by 6-metre by 380-millimetre thick con-crete panels, pinned together with 30-millimetre by 500-millimetre epoxy-coated smooth steel dowels inserted every 300 millimetres. The 1,700 cubic metres of concrete used had a specifica-tion of 35 megapascals. Workers gave the panels a light broom finish. Langley, BC-based Sealtec used a special machine to install a pre-molded rubber inset be-tween the joints. Phase 2, executed between May and October 2016, included replacing the asphalt on three aircraft stands with con-crete pads. Built the same way as those on the remote parking/de-icing facility, contractors poured 925 cubic metres of concrete. G&E also removed seven existing manholes/catch basins and in-stalled five new ones and 460 metres of new sub-drains. Phase 2 also called for expanding the apron by 8,600 square metres, made possible by shifting portions of Taxiways A and B. This included about 10,000 square metres worth of asphalt milling and overlay work. G&E also made storm system improvements and upgrades. As well, G&E rehabilitated 18,000 square metres of existing asphalt areas on Apron IV with milling and a 70-mil-limetre overlay. Eighteen base cans for taxiway cen-terline lighting, installed and paved over in Phase 1, were exposed in Phase 2 so Comox Valley-based Raylec Power LP could install new LED fixtures. Phase 2 included the installation of 59 more base cans and LED fixtures. With the new remote parking/de-ic-ing facility, which Cunningham declares “a marked improvement operationally,” rehabilitated apron asphalt and park-ing stands and reduced demand on the apron, the airport is now ready to launch Phase 3 to accommodate rapidly increasing traffic levels and welcome nearly two million passengers a year.
