Simulation-Enabled Intelligent Decision Support for Planning Precast Concrete Production Operations

Advances in engineering technology and requirements for sustainable development are main drivers for changes and innovations in the current construction industry. The paradigm shift to precast construction moves conventional field construction efforts into the controlled environment of an offsite manufacturing facility.

Investigation of Innovative Methods, Tools and Processes on BC Housing’s First IPD Project

In this unique research project, the researchers will document and analyze the collaborative processes and technologies in a housing project, which follows a formal Integrated Project Delivery (IPD) approach. IPD is an emerging procurement method in the construction industry that engages all major stakeholders from the beginning of the construction project. However, there is still a great need for understanding better the required organizational settings, innovative processes, and collaborative tools in order to conduct successfully an IPD project.

Improved Lateral Supports for Fresh Masonry Structures at Construction Site

Despite significant development of various construction materials, masonry is still considered as one of the most cost-effective materials. However, they are often vulnerable to wind-induced lateral loads caused during construction stage (within 1 to 2 days of construction) when the masonry is yet to achieve full strength. Temporary bracing systems are often used to support these structures at construction site to avoid loss of materials and injury to workers. However, design of these temporary bracings is relatively subjective and tend to be very conservative to maintain safety at workplace.

Masonry Construction as a Solution for Healthy and Resilient Buildings: A Life Cycle Thinking Based Evaluation

This research aims at life cycle thinking-based comparison of popular wall material (i.e., wood, concrete, masonry, etc.) for institutional, commercial, and industrial (ICI) building construction in Canada. Empirical studies will be used to observe the deterioration of interior and exterior masonry wall systems in various climatic regions. Life cycle sustainability assessment would be used to evaluate social, environmental, and economic impacts. Alternative wall construction methods will be compared using a methodological framework that integrates TBL, resiliency, and occupant health.

Exterior finish coatings for building façade applications combined with phase change materials and thermochromic paint

The durability of building materials is an important criterion to ensure long-term performance of buildings exposed to various environmental loads. Particularly, exterior building surfaces are exposed to high solar radiation and temperature differences during the year which can considerably influence their durability due to thermal stresses. Additionally, in light of the increasing need for energy saving in buildings, reducing this thermal stress and temperature fluctuations on exterior surfaces of buildings could help with indoor room temperature regulation in buildings.

Use of Recycled concrete Aggregate to Produce Concrete Masonry Blocks

Concrete—the most common construction material in the world—represents the main component of construction and demolition waste. The excessive extraction of virgin aggregate from Canadian lands and water bodies destroys the habitats of many species and affects the natural flow of streams in lakes and rivers. One solution to address the growing solid waste challenge and preserve natural aggregate resources from depletion is the adoption of large-scale recycling of concrete waste into aggregate.

Learning non-local features for 3D reconstruction of buildings

The goal of this project is to help automate the process of scanning buildings with consumer digital cameras. Currently, fully automated scanning with a commercial camera produces inaccurate scans, while accurate scans require significant manual effort on each individual photograph (of which there are many) of the building to be scanned. We plan to use modern machine learning techniques to reduce the human labor required to create very accurate 3D scans of buildings.

Cyclic Freeze-Thaw Behavior of Geocell-Reinforced Bases

Geocells are a type of three-dimensional honeycomb geosynthetics that are widely used to improve the performance of paved and unpaved roads by reinforcing the base/subbase courses. It is approved to benefit the long-term performance of roadways and reduction of construction cost. Although geocell has been widely used in roadway construction in cold regions, showing measurable improvements, research regarding the cyclic freeze-thaw behavior of geocell-reinforced roadways is rather scarce.

Magnesium Based Aerated Insulation Development and Analysis

Every building has insulations. Unfortunately, it is not fire retardant. The materials contain toxic chemicals, The source of those materials is not local. MgO Systems has a solution for industrial construction and home building industries. This Alberta based company designs and manufactures prefabricated wall panel systems and structural insulated panels with high thermal efficiency, advanced energy efficiency and quick installation.

As-built 4D Feedback Control For Fabrication and Assembly

This proposal aims to develop a new fabrication model where the geometric compliance of components is not only controlled by the original design information but also accounts for the deviations (within tolerance) of the previously built components and calculated deviation on the component being built. The developed model allows for in-progress checking of fabricated components and tracking the termination points with respect to a periodically updated termination point on the design or target location.
