Review of project planning methods for deconstruction projects of buildings

Abstract

PurposeThe paper aims to provide a comprehensive overview of literature and methods that can be used for deconstruction project planning of buildings. Furthermore, shortcomings of the identified planning methods are presented and research gaps are identified. Design/methodology/approachRequirements to consider for the planning of deconstruction projects are defined, to help in the classification of planning methods. With the help of these requirements, in a detailed literature review strategic and operational planning methods for deconstruction projects are investigated and discussed.Requirements which are not met by any of the identified planning methods can be interpreted as research and/or documentation gaps. FindingsOn the one hand, the literature review shows that recent approaches deal with planning methods for deterministic time and resource scheduling. Furthermore, project costs can be well planned by several methods. On the other hand, the literature review reveals that recent approaches mostly do not consider risks and uncertainties, environmental hazards or specific safety issues. A major shortcoming is that applied planning methods can only calculate up to a specific level of detail, e.g. with a limited number of activities, due to a very high computational effort in solving such project planning problems exactly. Originality/valueTo the authors' knowledge, this is the first study that provides an overview of literature and methods for the deconstruction project planning of buildings and it is also the first study that unveils research gaps for future research. Furthermore, the classified planning methods assist in identifying suitable methods for the planning of future deconstruction projects.3

Selection Model of Building Demolition Method Based on Expert System

“…Previous studies tried to obtain criteria that influence the choice of optimal building demolition methods. Criteria that affect the structural characteristics are the shape and size of structures, unstable structures, extent of demolition, scale of construction, previous building use, health and safety [2,4,6,[8][9][10][11][12][13]. Whereas in terms of field conditions, there is a level of disturbance permitted, the presence of hazardous materials, environmental risks and the location of the structure [2,4,8,9,[11][12][13][14].…”

Whereas in terms of field conditions, there is a level of disturbance permitted, the presence of hazardous materials, environmental risks and the location of the structure [2,4,8,9,[11][12][13][14]. In addition, there are costs that must be safe and financially feasible [6,9,10,[13][14][15] and prior experience is needed as seen from the limits given by the client, structural engineer needs resources, transportation considerations [4,6,9,[11][12][13][14].…”

Meanwhile, in term of time, demolition in general must be conducted as quickly as possible [6,8,9,10,13,15], and the value of the materials to be recycled will be higher and better [6,9,10,14,15] The choice of demolition method is very important because it will have a serious impact and safety, recycle of materials and components and costs.…”

“…In addition, the recent approach related to demolition shows that time planning methods and influential resource scheduling are carried out just like previous experiences. The main disadvantage is that the planning method applied can only count to a certain level of detail with a limited number of activities [13]. Therefore, a very high computational effort is needed to enable practitioners to make quick decisions.…”

“…In addition, it is also necessary to consider the legal regulations on health and safety including border impact and protection. The need for adopting different asset removal methods will greatly affect the outcome of the project [4].…”
