2012 Honorable Mention the north Burlington Skatepark Project By David Youkhana tthe Alton Campus, which includes Nortonhe North Burlington Skatepark constructionproject was part of a larger development, Community Park (a large urban sports park), High School, Library and Community Centre. The skatepark was built right in the middle of this $50,000,000 (CAD) development. The skatepark is 14,000 ft2 (1300 m2) in area and has proven to be a destination not just for the citizens of Burlington but also for people from surrounding municipalities in southern Ontario. The Norton Community Park Project was lead by John George Associates. Part of the professional design team included van der Zalm + associates inc. and New Line Skateparks, which were responsible for the integration, concept development, and detailed design of the skatepark. Gateman Milloy was the General Contractor for the construction of Norton Community Park and Fig. 1: Phase I preparations subcontracted NewLine Skateparks to construct the skatepark. The construction value for the skatepark is $500,000 (CAD). The first part of the construction included rough grading, excavating, and building the footings. The next phase included forming all the banks and transition areas (refer to Fig. 1). Welded wire mesh reinforcement was installed and wet-mix shotcrete was placed and cut to meet the demanding tolerances that were listed in the specification. Finishers provided a smooth (but not slippery) surface to maximize the performance and minimize the potential hazards to the skaters. The transition and banks were shaped with a 7.5 ft (2.3 m) radius and ranged in vertical height between 4 and 5.25 ft (1.2 and 1.6 m). Wet-mix shotcrete material was pigmented to differentiate the transition between vertical and horizontal surfaces and allow skaters to better orient their position while jumping and completing tricks. Over 400 yd3 (300 m3) of concrete were used to complete the project (refer to Fig. 2 and 3). Shotcrete played a key role in the completion of this project. The extremely tight tolerances Fig. 2: Construction would have been difficult to meet using any other 46 Shotcrete • Winter 2013
