Terex Cranes Helps Construct Bridgewater Residences on the Lake
The nearly 3-year project will require multiple contractors working together to finish all phases of construction. MTN Forming, Inc. of Bolton, Ontario, is tasked with completing structural formwork. Throughout the project, a variety of cranes will be employed to erect the buildings. However, a majority of the day-to-day lifting will be left to 2 cranes towering over the worksite for approximately 2 years. On the Bridgewater project site, tower cranes fill the critical link between the ground and the multistory structures. They lift a wide variety of the construction materials, ranging from tools, concrete form work and rebar to structural steel, equipment and concrete. Careful planning for the number, type, height, jib length and capacity of the cranes must be considered, so the entire project site is covered where needed. MTN Forming relied on the expertise of Cropac Equipment Company and C&C Crane Services of Oakville, Ontario, to supply the right type of tower crane equipment, strategically positioned to efficiently serve all the company’s lifting needs. “We had just under 0.8 ha to cover, and we had to lift a variety of materials, including precast steel reinforced with core slab,” mentions Kevin Carey, owner of C&C Crane Services, of Bolton, Ontario. “The heaviest planned lift was 9,1 t at a 50 m radius.” In addition to what was lifted, the crane providers also had to consider ambient factors for selecting the best type of cranes for the job. “While being on the lake provides spectacular views for residents, we had to account for the high lakeside winds, lake-affect snow and extreme cold for the project,” says Joel Hunt, sales representative for Cropac. “Freestanding heights came into play for the project to reduce set-up time and cost, and we chose the cranes that gave us the highest freestanding height capability.” Cropac and C&C Crane selected the Terex® SK315 and SK415. The SK315 crane offers an 8 t to 16 t capacity, while the larger SK415 crane provides a maximum lift capacity of 20 t. Cropac delivered the cranes to the jobsite in September of 2016, and a crew of 6 workers from C&C Crane and Total Crane Rental, also of Bolton, Ontario, erected the units on-site. To assist in tower assembly, crew members used a Terex® AC 250-1 all terrain crane. The 250 t capacity class mobile crane features a long 70 m main boom length, which allowed crew members to quickly install the tower and jib sections for both cranes. Each of the heavy duty tower sections for both cranes measured 2,4 m x 2,4 m x 5,9 m. The shorter SK315 crane was built with 9 tower sections under the 40 m long jib for a total freestanding height of 54.5 m. For the first phase of building construction, the SK415 crane was built with 11 tower segments to a height of 65.5 m to clear the SK315 crane when working at radius, and it included a 50 m jib. As work advances on the 22-story structure, another 5 tower sections with tie-back to the structure will be added to the SK 415 crane for a total hook height of 95.2 m. Work on the $210 million complex is quickly progressing with the formwork shell beginning to reach toward the sky. The Terex tower cranes are proving their worth, working in all kinds of weather conditions – sun, rain and snow – to help make sure workers have the tools they need to keep on schedule. With a professional sales team possessing in-depth industry knowledge and a capacity for listening to customer needs, Cropac Equipment Company has been equally committed to its customers and quality service since operations began in 1977. It is a factory-authorized distributor for Terex and Demag crane equipment, which includes a complete line of hydraulic truck cranes, all terrain cranes, rough terrain cranes, crawler cranes, boom trucks and tower cranes. |
