Target Cost Modelling for Offsite Construction Projects

• The fast-paced progress associated with offsite construction projects necessitates special attention toward project design, estimation, and planning. Traditionally, the relationship between project design and cost lacks clarity during the early design stages of a project. While design efforts aim to improve the project performance, compromises are made in order to meet a desired targeted cost. Target cost modelling (TCMd) provides an ideal environment to explore the available alternatives and reveal the associated financial and environmental impact on the project. Structural design, building envelope, heating and cooling systems, delivery of modular units, and onsite assembly are analyzed and standardized through a set of construction, costing, and energy factors in order to illustrate their indirect/direct effect on the project design, cost, and energy efficiency. This research presents a novel solution for standardization of best practices for offsite construction projects, where a target cost model of the project is developed dynamically and interactively as the design/planning matures. Such advances for offsite construction as improved project performance, reduced energy consumption, and enhanced design and estimating processes are expected. Data is collected from 25 projects constructed between 2010 and 2015, located in 12 cities spanning four Canadian provinces—Alberta, Saskatchewan, British Columbia, and Ontario, including eight offsite manufacturing facilities and three on-site assembly management branches. The diversity of the collected data provides a good sample representation of offsite construction projects.
