Straightedge and compass construction problems are one of the oldest and most challenging problems in elementary mathematics. The central challenge, for a human or for a computer program, in solving construction problems is a huge search space. In this paper we analyze one family of triangle construction problems, aiming at detecting a small core of the underlying geometry knowledge. The analys...

The progress monitoring (PM) of construction projects is an essential aspect project control that enables the stakeholders to make timely decisions ensure successful delivery, but ongoing practices are largely manual and document-centric. However, integration technologically advanced tools into has shown potential automate PM (CPM) using real-time data collection, analysis, visualization for ef...

Accurate selection and location of mobile cranes is a critical issue on construction sites, being able to contribute the improvement safety efficiency lifting operations. Considering complexities dynamics this study aimed develop useful approach for automated localization based simulation crane First, information required analyzed extracted from BIM (building modeling). Then, mainly considering...

In the Architectural-Engineering-Construction & Facility Management industry, project progress tracking is an important management task. Currently, this task still requires a significant amount of non value-adding manual effort that interferes with value-adding work. Additionally, current practice may lead to approximate or unreliable results. In this paper, the authors present an approach fusi...

Contour Crafting is an emerging technology that uses robotics to construct free form building structures by repeatedly laying down layers of material such as concrete. The Contour Crafting technology scales up automated additive fabrication from building small industrial parts to constructing buildings. Tool path planning and optimization for Contour Crafting benefit the technology by increasin...
