Low accuracy in the estimation of construction costs at early stages of projects has driven
the research on alternative costing methods that take advantage of computing advances …

Case-based reasoning (CBR) has been widely adopted in construction management (CM)
research due to the similar mind-sets of CBR and CM problem solving. However, to date …

Purpose Accurate and timely cost prediction is critical to the success of construction projects
which is still facing challenges especially at the early stage. In the context of rapid …

Construction projects require huge amounts of capital and have many risk factors due to the
unique industry characteristics. For a project to be successful, accurate cost estimation …

Cost estimation for public projects includes, but is not limited to, construction costs and
engineering services costs. The available cost estimation models for these projects focus on …

Quality problems are crucial in construction projects since poor quality might lead to delays,
low productivity, and cost overruns. In case preventive actions are absent, a lack of quality …

In this paper, we propose a hybrid case-based reasoning (CBR) system for predicting the
construction cost of high-rise buildings at the preliminary design stage. First, the extracted …

In the long-term use of the Case-based reasoning (CBR) model for early-stage construction
cost estimation, a typical issue is the unstable knowledge structure when the actual data …

Purpose Applied a hybrid approach using genetic algorithms (GAs) for a case-based
retrieval process in order to increase the overall improved cost accuracy for a case-based …

Conceptual cost estimation is an important step in project feasibility decisions when there is
not enough information on detailed design and project requirements. Methods that enable …
