Abstract

Using BIM to support Habitat for Humanity: A case study Building Information Modeling (BIM) is a digital, parametric, model-centric approach toproject delivery in the AEC industry. Among the many advantages of BIM is the ability toaccurately model real-world construction as well as to embed information in the components ofthe computer model. These can include attributes such as the physical properties of buildingcomponents and the cost of components and materials. This information can be extracted fromthe model for analysis. Additionally, any changes to the geometry of the BIM model canautomatically update information queries such as schedules and cost estimates. This paper documents a graduate level research project developed to investigatestrategies to enable a local chapter of Habitat for Humanity, often referred to as Habitat, tooptimize project estimating and scheduling by utilizing BIM. Habitat is an international non-profit organization that builds and repairs housing for low income families by utilizing the laborof volunteers and partner families, efficient building methods, modest house sizes and no-profitloans. While the project is based on a standardized housing prototype, there are typicallyvariables related to labor and material expenses on each individual house that is constructed. Forthe local Habitat associated with this project, each project varied in terms of material and labordonations, particularly in regards to project components that required skills beyond that ofvolunteers such as foundation work and mechanical system installation. The project goal was to utilize BIM in a manner which could assist Habitat in twoprimary ways. The first was to develop a method to document the cost variances and the use theBIM model to generate estimates for each individual project using the prototype. The second wasto use the BIM model to assist in helping volunteer laborers to better visualize the constructionsequence. This required the development of atypical modeling and cost estimating approaches.The paper documents the evolution of the project, modeling strategies that were employed, andthe final project outcomes. It also identifies further refinements that can be made to scale theproject to adapt to a wider range of Habitat projects.
