3:30pm - 3:50pm Creating Digital Twin for Sydney Opera House
Sydney Opera House is a cultural icon which accommodates an average 1800 performances and 1.4 million visitors per year. Employing 8500 people with annual maintenance costs of approx 30M AUD, its total value to Australia has been estimated at 4.6B AUD. The Opera House has been a strong advocate (the first in the world) of the concept of BIM for FM since nominated in 2004 as the Cooperative Research Centre for Construction Innovation exemplar project for FM as a business enabler. Declared a UNESCO world heritage site in 2007 and celebrating its 40th anniversary in 2013, the Opera House has commenced a long term renewal program. Around 20 disparate technical systems have historically been used to manage the estate and there has been no centralized resource to access and manage data. Development and implementation of a world class integrated BIM for FM solution (Digital Twin) improves operational and cost efficiencies to support greater visitor experience and plays a significant role in conservation and providing safe environments for staff and visitors, all in support of the Opera House’s cultural program. The Digital Twin was established in 2016-2018, and the presentation will describe the project and the future plans for the development of the solution.
4:10pm - 4:30pm Building Stronger and Greener with Structural Insulated Panels (SIPs)
Reducing the carbon footprint of buildings during and post construction can make a significant contribution toward saving our planet. Choosing to build with Structural Insulated Panels (SIPs) can help, because: a) waste material from SIP fabrication is recycled, b) construction job site waste is significantly lower than with conventional 2x framing, and c) energy requirements for SIP buildings are significantly lower. The most common skin material for SIPs is Oriented Strand Board (OSB), which is made from a sustainable resource, doesn't produce off-gassing, and can be treated to resist mold, rot, and insects. Engineered for strength and durability, OSB is well-suited for load bearing applications in building construction. It can be produced in sheets as large as 8' x 24', allowing OSB SIPs to be used on large structures. Fabricated and tested in a certified production facility, SIPs are cut to size, and windows and door openings are created during production. Waste is recycled into new panels or other uses. SIPs are delivered to the building site labeled and ready to install, thus reducing waste and helping maintain a clean, safe work site. Structurally, a standard SIP can resist 70% more vertical load and 35% more lateral loads than standard 2x framing. With 2x framing, the top plate can move relative to the bottom plate (aka racking), which creates cracks in exterior finishes, sticky doors and windows, and interior nail popping. Those issues are not found with SIPs as they cannot rack. Design details and installation of SIPs is significantly simpler than with conventional framing, saving time and costs. When used as the roof structure, SIPs can span as far as 24 feet, requiring much less sub-structure than conventional framing, which requires a sub-structure member every 2 feet. SIPs are extremely more energy efficient than conventional framing and meet new environmental codes for continuous insulation. Wood and steel studs allow heat transfer through walls, requiring more energy to maintain interior comfort levels. Since SIPs have no studs, the pathway for energy transfer is eliminated, resulting in comfortable temperatures year-round with lower energy costs. Because SIPs are sealed, air can't pass through walls, roof, electrical outlets, and mechanical holes. Many studies have demonstrated that the cost of SIP construction as compared to conventional framing is roughly the same, and less than other building methods, e.g., steel, masonry, and concrete. Although initial material costs are a bit higher, people often fail to include the cost factors such as installation, insulation, shear sheathing, hardware, job site waste, HVAC requirements, and the cost of money as related to construction time. All factors considered the final cost of the framing with SIPs is the same or less than conventional framing. SIP construction is one of the best choices available today for building strong, energy efficient, cost-effective, and comfortable structures.
