Developing New Strategies to Evaluate Capital Construction Project Planning

Construction companies spend significant amounts of resources on front end planning (FEP). The potential to obtain substantial benefits from a strategic implementation of front end planning practices across an entire portfolio have made the evaluation of FEP an important issue for both project leaders and scholars. The opportunity now exists to mine the constituent elements of the index based on historical project data sets to develop methods for planning proactive strategies in capital projects execution.

Advanced Composite Materials to Rehabilitate Concrete Structures

This postdoctoral study is an experimental investigation on the bond behaviour of externally-bonded (EB) fibre-reinforced polymer (FRP) L-shaped FRP plates to the concrete substrate. This study will be the foundation of an upcoming comprehensive study on rehabilitation of reinforced-concrete (RC) beams with L-shaped FRP plates and end-anchored FRP fabrics. Recently, EB FRP composites are increasingly used to strengthen existing RC structures. However, de-bonding of FRP fabrics or plates is still a major issue.

Smart Water Distribution Systems to Conserve Energy and Water Year Two

Municipal water supply pumps consume a large amount of energy and have been shown through field testing to operate at efficiencies of approximately 10% less than their original condition on average. A proprietary technique for the optimal selection of pump combinations has been preliminarily developed and can be applied without any capital improvements to the system, but rather just the implementation of affordable sensing equipment and changes to operational logic of the pumps.

Hydraulic simulation models of water pipe networks with geographic nformation system (GIS) and global positioning system (GPS)

Water distribution systems are important civil infrastructures that must be adequately managed nd maintained in order to provide expected levels of service to consumers. As such, they have  need for on-line support systems based on continuous monitoring of hydraulic and water uality parameters within the system. The purpose of this project is to modify and test a ydraulic simulation model with support of Global Positioning System (GPS), which will allow onitoring and optimizing water utilization and detecting leaks and pipe bursts in each ousehold.

Rehabilitation of Concrete Pipes Using Honeycomb-FRP Composite Sandwich Infinite Pipe

The deterioration of our aging underground pipe network emerges as a critical problem. Concrete pipes may be damaged due to salt attack from outside and sulfide attack from inside, hence compromising its structural integrity. Repairs for such pipes are time-consuming and expensive. A revolutionary trenchless structural rehabilitation technique is introduced. In this technique Innovative honeycomb-FRP Composite Sandwich (HCS) are used for retrofitting concrete pipes (InfinitPipe™).

Perfectionnement des outils et pratiques de modélisation hydrologique pour l’évaluation des impacts des changements climatiques sur les régimes hydriques québécois

Les variations anticipées du climat pourraient venir perturber substantiellement le régime hydrique québécois, appelant les acteurs locaux de l’eau à redéfinir leurs modes de gestion ainsi qu’à mettre en place des stratégies d’adaptation. Les travaux engagés dans ce sens, initiés dans le début des années 2000 par Hydro-Québec, s’appuient dorénavant sur une collaboration (cQ2 : Hydro-Québec, CEHQ, Rio Tinto Alcan, Ouranos) visant à diffuser un message complet et cohérent quant au diagnostic des impacts sur les régimes hydriques en s’appuyant sur des bases scientifiques solides.

Development of a microbe granulation technology for the increased treatment of organic wastewater, removal of emerging containments and digestion of sludge

Today we are failing to properly and completely treat organic wastewater which results in large amounts of sludge buildup and many untreated emerging contaminates that are shaping and changing our environment. If we ignore this problem: we will see an increased need for resources to development new and very expensive mechanical processes to manage sludge, wildlife will experience further side effects, and the appearance of emerging containments that are causing additional side effects to the surrounding population will also continue to increase.

Control of point source low volume methane emission using methanobiofiltration technology

Methane is a key greenhouse gas (GHG), and atmospheric methane emissions in Alberta are associated with a variety of industry sectors: sanitary landfills, wood waste landfills, feedlot operations and the oil and gas sector. When the quantities released at individual locations are relatively small, this methane cannot be used as an energy source; therefore, environmentally acceptable methods are needed for their control. Recent research has shown that methanotrophic bacteria are capable of converting methane to carbon dioxide without producing toxic by-products.

Enquête sur l’état actuel de la productivité, des interdépendances et des conflits juridictionnels dans l’industrie de la construction : vers des alliances d’avenir

L’industrie de la construction est un secteur majeur au Québec puisqu’elle représente à elle seule 13% du PIB et 1 emploi sur 20. Cependant, la réglementation qui l’encadre pose quelques difficultés. Cette réglementation date de 1968 et il s’agit de la Loi sur les relations du travail, la formation professionnelle et la gestion de la main-d’oeuvre dans l’industrie de la construction, ou loi R-20. La problématique soulevée dans cette étude est la partie de cette loi relative à la formation obligatoire pour les vingt-cinq métiers du bâtiment.

Development and Validation of the Next GenerationSimulation Platform for High-Rise Buildings

Recent years have witnessed a boom in the construction of modern high-rise buildings in megacities around the world. It is important to design a high-rise building that can effectively withstand both wind and earthquake loads. Nonetheless, in current practice, the design of high-rise buildings for wind and earthquakes is done independently. Hence, there is an urgent need to develop a set of integrated design guidelines for both wind and earthquake loads.
