Construction cost estimators are confronted with the challenging task of estimating the cost of constructing one of a kind facilities. They must first recognize the design conditions of the facility design that are important~i.e., incur a cost! and then determine how the design conditions affect the cost of construction. Current product models of facility designs explicitly represent components, attributes of components, and relationships between components. These designer-focused product models do not represent many of the cost-driving features of building product models, such as penetrations and component similarity. Previous research efforts identify many of the different features that affect construction costs, but they do not provide a formal and general way for practitioners to represent the features they care about according to their preferences. This paper presents the formal ontology we developed to represent construction knowledge about the cost-driving features of building product models. The ontology formalizes three classes of features, defines the attributes and functions of each feature type, and represents the relationships between the features explicitly. The descriptive semantics of the model allow estimators to represent their varied preferences for naming features, specifying features that result from component intersections and the similarity of components, and grouping features that affect a specific construction domain. A software prototype that implements the ontology enables estimators to transform designer-focused product models into estimator-focused, feature-based product models. Our tests show that estimators are able to generate and maintain cost estimates more accurately, consistently, and expeditiously with feature-based product models than with industry standard product models.

“…Previous research on construction method modeling defines and represents construction methods as sets of generic activities required to install certain types of building components (e.g., Aalami 1998). The main components of construction method models are Components, Actions and Resources [CAR] (Darwiche et al 1988;Jagbeck 1994;Stumpf et al 1996;Froese and Rankin 1998;Aalami 1998). For automated planning, construction method knowledge explains why certain groups of construction activities and sequences exist.…”

“…The construction method template consists of two sections. The first section contains Component, Action, and Resource slots to capture the construction method attributes defined in previous research (Darwiche et al 1988;Jagbeck 1994;Stumpf et al 1996;Froese and Rankin 1998;Aalami 1998). The second section of the construction method template has options to describe the labor crew, equipment, hazard, and protected spaces associated with the construction method.…”

Construction activities require a set of work spaces to be executed safely and productively. The locations and volumes of these spaces change in three dimensions and across time, according to project-specific design and schedule information. Previous research on construction space management requires users to specify the spatio-temporal data necessary to represent each project-specific space needed for construction. Since a construction schedule consists of hundreds of activities requiring multiple types of spaces, this approach is practically infeasible. There is a need for a generic (projectindependent) representation of work spaces, from which the project-specific instances of spaces can be derived automatically based on project-specific design and construction schedule information. This paper formalizes such a generic space description as a computer-interpretable ontology. This ontology is general, reusable and comprehensive. It enables a prototype system that captures the spatial requirements associated with construction methods and automates the generation of project-specific spaces represented in three dimensions and across time.

“…The importance of automated planning research performed to date, as it relates to this work, is the formalization of construction planning knowledge and the approaches taken to capture this knowledge for future use (Echeverry, 1991;Shaked and Warszawski, 1995;Yamazaki, 1995;Stumpf et al, 1996). Similar to the work by Fischer and Aalami (1996), Jägbeck (1998), andChevallier andRussell (1998), the approach adopts the concept of storing and retrieval of planning knowledge through the use of templates.…”

This paper discusses the future requirements of integrated construction management systems and the need to support the management of large volumes of information on several levels. The solution proposes a combination of an efficient user interface and methods to partially automate the creation of the required information through access to stored information from past projects. The research follows the path being established for integrated construction management systems that rely on a standard representation of the industry's information requirements. By exploring the comprehensive aspects of construction planning for an integrated construction management system, the research demonstrates the usefulness of applying sound information representation structures. Through the application of case-based reasoning, the research advances the concepts of planning tools as they apply to integrated systems. The resulting prototype construction management system has the primary characteristic of assisting the user in the manipulation of information in order to generate the initial information requirements of an integrated construction management system.
