Abstract
Recently, new methods and technologies, including building information modeling (BIM) and lean management, have been introduced to the construction industry. Their objectives are to increase collaboration, ensure smooth flows of information, improve productivity, reduce different types of waste, and stabilize production. These constraints have forced the industry to gradually change by applying more adapted operational processes and contractual models that focus on value and by integrating the design, construction and operation phases. Traditional scheduling methods based on activities modelling have become less adapted to this new reality. As a result, complementary concepts have emerged, particularly the Last Planner system, takt time, space planning, and spatiotemporal scheduling. This paper presents an extensive review and an assessment of the state of the art of the spatiotemporal planning of construction projects. The paper categorizes the research efforts, presents a timeline of the most significant scientific developments in this domain, and addresses their possible impacts on the construction industry.
Highlights
Since the early 1990s, a new range of planning techniques specific to the construction field has begun to emerge based on the management of construction site spaces
The availability of space represents a significant constraint for the planning of construction projects and dictates the duration of projects
Traditional scheduling methods focus on tasks and constraints and do not convey workspace occupation or space availability (Akinci et al, 1998)
Summary
Since the early 1990s, a new range of planning techniques specific to the construction field has begun to emerge based on the management of construction site spaces. No research has been published in the past demonstrating a literature review and an assessment of the state of the art of space planning for construction projects. A timeline and an analysis of the state of the art of research on construction project space planning are presented. The content of the papers was reviewed to determine if the research was innovative, original, and relevant to the research subject This more in-depth validation was conducted considering an interest index and the authors’ knowledge of the field. The conceptual review and a detailed analysis of the 101 publications selected led to the identification of two classification categories: 1) Research topics: site layout, theoretical concepts, spacetime flow, workflow, material flow, and 3D + time and 2D + time visualization.
