Building Information Modelling (BIM) represents a long-term investment that could allow reduction of time and cost control by optimising design and construction processes. It also ensures greater effectiveness of control systems. The paper is focused on a public procurement case study regarding the BIM-based validation and construction optimisation of an actual residential building designed in ...

The construction site layout (CSL) design presents a particularly interesting area of study because of its relatively high level of attention to usability qualities, in addition to common engineering objectives such as cost and performance. However, it is difficult combinatorial optimization problem for engineers. Swarm intelligence (SI) was very popular and widely used in many complex optimiza...

Mobile cranes are used to lift heavy modules in industrial projects. These heavy modules are often prefabricated and each project consists of a large number of lifts (e.g., a typical industrial project may have between 150 and 1000 modules to be lifted). To ensure the safety and efficiency of these lifting activities, crane motion planning is needed. However, in practice, most of the heavy lift...

SightPlan is an expert system that performs construction site layout. The system contains an explicit representation of the strategy it follows to construct a solution. Based on the assumption that the cognitive capabilities of an agent have an impact on the strategy that agent follows during problem-solving, we decided to experiment with alternate strategies. We modeled one strategy after the ...

BACKGROUND Health and safety (H&S) on a construction site can either make or break a contractor, if not properly managed. The usage of Building Information Modeling (BIM) for H&S on construction execution has the potential to augment practitioner understanding of their sites, and by so doing reduce the probability of accidents. This research explores BIM usage within the construction industry i...

Based on the current situation of temporary pipelines with disorderly layout and low integration, roads time consuming, material consuming environmentally unfriendly in, construction site, a new type reusable assembly power pipe trench road system technology is proposed in this paper. The research background ideas are described; partition, structure connection designed; stress checked by finite...

Meta-heuristic algorithms proved to find optimal solutions for combinatorial problems in many domains. Nevertheless, the efficiency of these algorithms highly depends on their parameter settings. In fact, finding appropriate settings of the algorithm’s parameters is considered to be a nontrivial task and is usually set manually to values that are known to give reasonable performance. In this pa...

While handling deformable linear objects (DLOs), such as hoses, wires or leaf springs, with an industrial robot at high speed, unintended and undesired oscillations that delay further operations may occur. This paper analyzes oscillations based on a simple model with one degree of freedom (DOF) and presents a method for active open-loop damping. Different ways to interpret an oscillating DLO as...
