We assessed relationship between turbidity luminosity factors how this might affect calculation survey...

The construction industry requires concrete with adequate post-cracking behavior for applications such as tunnels, bridges, and pavements. For this reason, polypropylene macrofibers are used, which synthetic fibers that fulfill the function of providing residual strength to concrete. In study, an experimental plan is carried out evaluate bending reinforced using four-point test according ASTM C1609. Three fiber dosages (3.6, 7.2 10.8 kg/m3) three lengths (40, 50, 60 mm) were used. use macro...

Compared with other industries, construction has maintained one of the lowest growth rates in productivity and innovation over last decades. Moreover, low compliance schedule targets remained a common issue throughout projects. Therefore, although methodologies developed have benefited design, operation, meeting client project objectives becomes challenging without properly integrating organization, information, systems processes. This perspective introduces Virtual Design Construction (VDC)...

Compressive strength and elasticity modulus are the main mechanical properties of concrete. The non-destructive ultrasound pulse test can be used to determine these without compromising structure’s integrity. This study seeks assess whether a correlation exists (1) between Reinforcement Index (RI) properties, (2) RI dynamic (3) among polypropylene fiber-reinforced was modified through fiber volume fraction (0, 0.4, 0.8 1.2%) length (40, 50 60 mm). were assessed ultrasonic velocity (UPV),...

The introduction of artificial intelligence methods and techniques in the construction industry has fostered innovation constant improvement automation monitoring control processes at sites, although there are areas where more studies still need to be conducted. This paper proposes a method determine criticality cracks concrete samples. proposed uses previously trained YOLOv4 neural network identify cracks. Then, region interest, determined by bounding box resulting from model...

The novel coronavirus, SARS-CoV-2, has the potential to cause natural ventilation systems in hospital environments be rendered inadequate, not only for workers but also people who transit through these even a limited duration. Studies of fields geosciences and engineering, when combined with appropriate technologies, allow possibility reducing impacts SARS-CoV-2 virus environment, including those hospitals which are critical centers healthcare. In this work, we build parametric 3D models...

A manually classified dataset of images obtained by four static cameras located around a construction site is presented. Eight object classes, typically found in environment, were considered. The consists 1046 selected from video footage frame extraction algorithm and txt files containing the objects' class coordinates information. These data can be used to develop computer vision techniques engineering fields.

Undergraduate programs face the permanent challenge of constantly transforming to keep an up-to-date curriculum according globalization and internationalization processes. In case civil engineers, professional training should respond needs Architecture, Engineering, Construction, Operation (AECO) industry. this context, Building Information Modelling (BIM) constitutes a process involving shared digital representations built assets facilitate design, construction, operations processes within...

The Barcelona method was developed as an alternative to other tests for assessing the post-cracking behavior of fiber-reinforced concrete, with main advantage being that it uses significantly smaller specimens compared methods. For this reason, can provide a solution characterizing concrete in hard-to-reach constructions such roads and tunnels. On hand, polypropylene (PP) fibers have gained increased attention recent years within scientific community due their high tensile strength...

Production metrics (PM) are important yardsticks for AEC (Architecture, Engineering, and Construction) teams to determine whether their projects on track. This paper reports research that looked empirical evidence of the use PM from literature (PML) in practice. Specifically, this classified reported by 279 VDC (Virtual Design professionals Scandinavia Latin America into 17 PML. About 3 PML (detailed schedule conformance, stakeholder involvement, meeting efficiency) were found be more than...
