The St. Lawrence River harbours a complex ecosystem whose physical properties vary from upstream to downstream. It includes lakes and freshwater reaches, a long estuary, and a gulf with marine features. The area is home to richly diverse habitats and an equally rich diversity of flora and fauna. It is a natural resource to be sustained and preserved. The attempt of SSL construction is to perform an in-water installation of precast elements. This is to avoid minimal intervention to Saint Lawrence ecosystem and life and economical cycle.
This project will develop inclusive design standards and methods for Oxford Properties to assess and improve the accessibility of their residential, office and retail property holdings and to promote customer service excellence for seniors and people with disabilities in Oxford properties across Canada. Areas that will be encompassed by the new design standards are: signage, kiosks, customer service, stairways, parking, external paths, emergency, staff/service areas, common halls/doors and furniture/fixture/finishes.
By studying and modeling of current production process, a physical training assembly system is built in a small scale with the exact same process, tooling as the full scale one. Along with leaning management system constructed, which includes a set of multi-media training materials, new employees can get familiarized with the manufacturing process in a shorter frame compared to traditional training. Also, by implementing what-if analysis, results from this physical simulation can be used to study and improve current full size production process.
The Gettingg to Groundbreaking project 2015-16 seeks to engage two masters student interns for Sept 2015-June 2016 in order to complete original research into the home building policy and process applicable to high-rise developments in municipalities in the Metro Vancouver region and Abbotsford The interns will conduct survey, interview, secondary and case studyba. sed research, consultation across the spectrum of interests in housing policy and development issues, and will construct and maintain a unique database, for a third annual iteration of this study.
This project is designed to verify the performance of a wireless Smart-Rock sensor that is embedded in concrete during construction for non-destructive quality control at low temperatures. Various laboratory experiments will be conducted using the smart sensor at Queens University on different concrete mixtures at low temperatures. The data from these sensors are analyzed using a proprietary algorithm to estimate the compressive strength of concrete in real-time. The results will be validated against those obtained by direct compression test on cylindrical specimens.
The growing demand to establish comprehensive BIM standards is demonstrated by a proliferation of both national (BIM Task Group in the United Kingdom and BIMForum in the United States) and international (buildingSMART Alliance) organizations working to that end. Adding to the sense of urgency is pending legislation in the United Kingdom (2016) that will require a BIM for all government building contracts over ?5 million.
The structural performance of skyscrapers subjected to natural hazards such as strong winds and earthquakes has significant effects on the resilience of a city because of the recent boom in the construction of skyscrapers around the world. However, resilience is currently not explicitly considered in the design of tall buildings. Studies show that modern tall buildings can suffer significant damage due to natural hazards and they might need to be closed for up to 23 years for repair. This has serious socio-economic repercussions.
Laser marking uses laser power to make permanent signs on product surface. In 2012, World Star Technologies developed the first portable laser marking machine in the world by replacing the conventional galvanometer based scanning head with a 2D micromirror. It reduces the size, weight and price by 1000, 5 and 10 times. However it has limited marking area due to the limited rotation angle of the micromirror. It is highly desired by the customers to have a larger marking area to be used in more applications.
Powder coatings are more environmentally-friendly and cost-effective than liquid coatings. However, the use of coarse coating particles leads to high film thickness and inferior visual appearance, and these defects limit their use where high precision and highly aesthetic effects are required. To obtain a smooth coated surface, the use of fine powder is necessary. However, this gives rise to many problems which need to be overcome to allow proper application of the fine powder.
Self-tapping screws (STS), when compared to traditional wood screws, are longer and have improved thread geometry, and are made of hardened steel which increases their axial, bending, torsional, and most importantly also their withdrawal capacity. The use of STS in connection assemblies, however, is not standardized and their advantageous performance when implemented at an angle to the grain cannot be fully utilised unless proven by testing.
