The architecture, engineering, construction, and operations industry faces an urgent need to enhance construction and demolition waste management in urban areas, driven by increasing demolition and construction activities and a desire to align with sustainable practices and the circular economy principles. To address this need, a systematic literature review on the building information modelling methodology was conducted, employing a structured protocol and specific tools for the analysis of academic studies, based on PRISMA guidelines and StArt software (version 3.4 BETA). Ninety relevant studies published between 1998 and 2024, were analysed and selected from the Web of Science, Scopus, and Engineering Village databases. Findings indicate that China leads in publications with 34%, followed by Brazil (8%) and the United Kingdom (7%). The analysis emphasises the use of drones and LiDAR scanners for precise spatial data, processed by 3D reconstruction tools like Pix4D and FARO As-Built. Revit excels in 3D modelling, providing a robust platform for visualisation and analysis. Visual programming tools such as Dynamo automate processes and optimise material reuse. The study presents a conceptual framework that integrates these technologies with the principles of the circular economy, clarifying the interactions and practical applications that promote the sustainable management of demolition waste from urban buildings and process efficiency. Although the approach promotes material reuse and sustainability, it still faces barriers such as the need for waste segregation at the source, the adaptation of innovative technologies, like the iPhone 15 Pro LiDAR and thermal cameras, as well as associated costs. These factors may limit its adoption in larger-scale projects, particularly due to the increased complexity of buildings.

The interest in sustainability in the construction industry arose in the 1990s, and current studies have created models to predict environmental aspects. Previous quantitative research to investigate environmental aspects was based on the perception of specialists. The present article proposes a methodology applicable to urban infrastructure activities in order to quantify environmental aspects by applying duration and severity criteria, using calculations founded in the scientific literature. The quantitative methodology to assess environmental aspects calculated ten aspects for six construction activities based on duration and severity criteria, eliminating the judgement of the latter criterion of earlier methodologies. The results revealed five significant environmental aspects: greenhouse gas emissions, energy use, noise pollution, water pollution, and soil pollution, due to the type of construction, which required a large amount of equipment that impacted the atmosphere, soil, and water. Possibly for the first time, urban projects can be objectively assessed based on a methodology that quantifies environmental aspects in the pre-construction phase.

The accelerated development of construction has positively boosted the economy but caused environmental pollution. The objective of this article was to propose a model to quantify and identify the causes of environmental aspects in urban infrastructure projects during the pre-construction phase. The methodology included ten environmental aspects and six construction activities, distributed in three phases: quantification, preparation of an inventory and identification of the main causes of environmental aspects. The results of projects A, B and C confirmed five environmental aspects with quantifications of the maximum normalized unitary ratios, namely greenhouse gas emissions with 1.00, 1.00 and 1.00; energy use with 0.99, 0.99 and 1.00; noise pollution with 0.84, 0.89 and 1.00; water use with 0.95, 1.00 and 0.96 and use of resources and raw materials with 1.00, 1.00 and 1.00, caused by the construction methods, machines, materials and environmental conditions of the urban infrastructure project. This proposal was the first initiative to analytically and previously investigate the environmental performance of future infrastructure works, assisting in the strategies of the pre-construction phase and improving the decision-making process regarding environmental issues in constructions. Finally, this initial effort may evolve to create opportunities to avoid, mitigate, reduce or accept the environmental effects in the infrastructure projects in developing countries.

The objective of this work is to map, in a limited area inside and outside of the worksite, the environmental impact generated by sound pollution coming from the driving of foundation piles for high rise buildings, as well as to observe and check if the noise levels produced by the emitting source are tolerable in the urban environment. The methodology of the work includes a survey of technical references about the subject; measurement of noises surrounding the worksite during the foundation phase for four distinct buildings, with different types of piles: prefabricated piles, continuous helical displacement piles , traditional compaction piles and Terra Probe compaction piles. A grid of points was built due to the time of driving and after that the measurements of environmental noises were performed emitted by the execution of each type of pile using a sound level meter. The interpretation of the measurements and their impacts on the neighborhood of the building were performed using the computational tool Suffer for creating noise level contours. The X and Y axes of the grid represent the distances in meters of the area studied and the Z axis represents the noise measured in dB. The contours developed represent the mapping of the noise at the worksites and their surroundings. The mapping of the urban impact of noise, the measurement of its dimensions, and the examination of its propagation around the building are important subsides to adequate individual and collective protection procedures. Seventy one points were measured at four building sites with different types of piles, and the results showed that at only three points was the noise within the limits of the Municipal Law of Recife of 70 dB, which proves the relevance of the research. Finally, the comparative analysis between the four types of piles shows that the continuous helical displacement pile emits the lowest noise level among the four pile types studied.

A administração pública brasileira movimenta expressivos recursos na construção civil, mas enfrenta falhas no planejamento das obras, desde a fase de pré até a pós-construção. Esta pesquisa objetiva analisar as causas dos aditivos contratuais em uma obra pública localizada em Recife-PE, com base na aplicação do método de gerenciamento do valor agregado (Earned Value Management – EVM). A metodologia foi estruturada em quatro etapas: revisão da literatura, estudo de caso, aplicação do método EVM e desenvolvimento de proposta simplificada de gerenciamento. Os resultados revelaram falhas no planejamento inicial e a importância do uso de ferramentas como o EVM para identificar desvios. Como contribuição, o estudo propõe um framework prático de mitigação de atrasos, destacando a necessidade de integração entre planejamento e execução.
