    A comparison of currently available resource leveling methods used in construction
    (University of New Brunswick, 1990) Rankin, Jeff H.; Waugh, L.; Waugh, Lloyd
    The capabilities of two heuristic-based methods and one optimization-based method for resource levelling are examined. Four different projects are used for this examination. Of the two heuristic methods one is determined to be inappropriate and the other is best suited for resource allocation. The optimization model works well for resource levelling and not for resource allocation. Both the optimization and one of the heuristic methods are useful in their specific application. However improvements can be made to each method to improve it's usability.

    Quantifying safety in off-site construction
    (University of New Brunswick, 2022-06) Odo, Nicole Tamara; Rankin, Jeff H.
    The concept of leveraging off-site construction as a safer alternative has been presented by researchers and industry, but support of this with quantifiable data is lacking. To investigate differences in off-site construction versus conventional on-site methods, the research has developed a safety evaluation methodology to quantify safety risks and allow for comparisons. The methodology leverages historical safety data from the Province of New Brunswick to provide inputs for a risk-based process analysis. The methodology is partially validated in its’ application to two case studies: a mid-rise modular hotel construction project that employed both conventional and off-site construction methods, and a prefabricated panel installation. The evaluation takes a construction product-focused approach with emphasis on defining a complete material supply chain. The case studies demonstrated the generalizability and feasibility of the evaluation method, and also found off-site construction to be safer in the specified context of the mixed method hotel construction.
