“…In other words, construction requirements represent the key pre-conditions for construction (Chua and Yeoh 2011). This then forms the basis for representing construction knowledge; the knowledge embedded within the construction requirements drive the planning process by providing a key tool for constructability analysis of a construction project.…”

This paper presents a generalized, flexible and formal framework for representing various requirements to support the needs of the construction process using the Industry Foundation Classes (IFC) model specification. These are termed construction requirements. The importance of considering construction requirements as a representation of construction knowledge within the context of construction planning and scheduling will be discussed, allowing readers to gain an understanding of the applicability of construction requirements.An ontological model for describing these construction requirements will be proposed in this paper, which will aid in formulating a uniform representation schema for construction requirements. This model will define the attributes of the construction requirements ontology from the perspectives of spatial, temporal and ordinal characteristics. From these attributes, various construction requirements may be represented as construction requirement entities. These construction requirement entities demonstrate how the functional and non-functional characteristics of a building element system may be captured for constructability analysis. This paper concludes by explaining how the construction requirements may be extended to represent construction methods, and underlines its applicability to automated constructability analysis, as well as automatic schedule generation.

“…In a construction project, schedule constraints represent the construction requirements that a schedule must satisfy. They define the precedence relationships among activities as well as the sequences that construction processes may follow (Chua and Yeoh 2011). Each constraint exhibits different influence to the schedule according to its characteristic and/or the activities involved.…”

In construction scheduling, constraints among activities are vital as they govern the schedule solution. Understanding their criticality is essential for better schedule management. This paper presents a systematic method to identify and classify the criticality of schedule constraints for the schedule management from the constraint perspective. In terms of criticality, schedule constraints can be grouped into four types: project-critical, activity-critical, sequence-critical and non-critical. Project-critical constraints are those which govern start/finish time of critical activities and the project end time. Activity-critical constraints define the start/finish time of non-critical activities, and sequence-critical constraints are those whose existence affect the start/finish time of some activities or the project end time. Constraints belonging to any of these groups are vital to a schedule as they cannot be removed from the constraint collection. Non-critical constraints, on the other hand, do not govern either start/finish time of any activity or the project end time. Accordingly, non-critical constraints are redundant and can be removed from the constraint collection without causing any change to the schedule solution. The method proposed was applied to a case example for further interpretation. The proposed classification scheme could shed light on a more in-depth understanding of the nature of criticality and the role of constraints in a schedule, and thus better schedule management may be achieved.

“…Although there is abundant literature on the management of stakeholders' needs in general (Smith and Love, 2004;Takim, 2009;Yuan et al, 2010;Jennings et al, 2013;Yang and Shen, 2014), typical construction processes lack practical frameworks for specifically managing the owner´s needs (Shen et al, 2004;Yu et al, 2010;Chua and Yeoh, 2011;Yu and Shen, 2013). In most cases, owners express their needs on the basis of their previous construction experience but the reliability of this strongly decreases with the project complexity (Kamara et al, 1999 and2000b;Lima et al, 2011).…”

“…Needs are the stakeholders' expectations concerning the construction product (Kamara et al, 2000a;Chua and Yeoh, 2011) and must be processed and formally translated into requirements (Lima et al, 2011;PMI, 2013). Project management ensures the understanding of the stakeholders' needs and their accomplishment by coordinating the activities of every project stakeholder (Yuan et al, 2010;PMI, 2013;Yang and Shen, 2014).…”

Abstract. Building life cycle is a process which covers not only the construction phase but also the feasibility, the design and the operation phases. Identifying the owner's needs in all phases of this process is of paramount importance for achieving satisfactory results for the building project. Additionally, the owner's needs should be fulfilled by the work scope of every stakeholder involved in the project. Nevertheless, these needs are not always adequately considered in building projects. Thus, the purpose of the research reported in this paper has been to develop a model that allows for the identification of the owner's needs in all phases of the building life cycle. The article presents a six level classification system for the information required in the project and a two-dimensional model that maps the life cycle and the logical actions to be undertaken in each phase. The model has been corroborated and improved by applying the Delphi technique to a panel of ten experts in two rounds. The practical use of the model is through the systematic application of a series of questionnaires built upon the information classification system for determining the owner's needs. The paper details the operation phase of the model as an illustrative example and a case study on a residential building project of twelve apartments in Spain.
