Assessing the environmental impact of construction waste management in northern Thailand: An approach to estimate greenhouse gas emissions and cumulative energy demand

Over the past century, the world has grappled with the looming challenge of climate change, with the construction sector emerging as a significant greenhouse gas emitter. This research aims to estimate greenhouse gas (GHG) emissions, cumulative energy demand (CED), and associated disposal costs by applying life cycle assessment (LCA) principles to the disposal of construction materials in northern Thailand. The study employs LCA as the analytical method, focusing on the disposal of concrete, steel, and wood waste from residential construction projects. The life cycle inventory analysis investigates waste management practices, including on-site landfilling, recycling, and transportation with an average distance of 30 km. The findings reveal that concrete waste is the primary contributor, with transportation playing a pivotal role. In the conventional case, total GHG emissions reach 38.624 kgCO2eq/m2, with CED at 12.991 MJ/m2 and disposal costs totaling 420.97 THB/m2. Three waste management scenarios are explored: Scenario 1 (50% on-site landfilling, 50% reuse/recycling), Scenario 2 (75% on-site landfilling, 25% transportation landfill), and Scenario 3 (100% on-site concrete landfilling, 100% steel reuse/recycling, 100% wood waste landfilling). Scenario 3 shows a significant 20.3% reduction in GHG emissions, a 90.5% decrease in CED, and a disposal cost reduction of 20.9% compared to the conventional case. This study underscores the importance of strategic waste management decisions, highlighting the potential of sustainable practices to foster an eco-friendly construction sector. Its findings offer valuable insights and recommendations, advocating for refined strategies like prioritizing recycling, optimizing transportation, and minimizing incineration to effectively reduce emissions and promote environmental responsibility in construction.

Multi-Criteria Assessment of Timber-Based Structural Systems for a Grocery Store

To reduce the negative impact on the environment, architects, designers, and construction companies need to find and apply eco-friendly and sustainable building solutions. Due to its renewable nature and numerous advantages, timber has become an attractive substitute for steel and concrete in both residential and non-residential construction projects. However, timber application in the construction of grocery stores is a relatively new concept. The purpose of this research is to propose three alternative timber-based structural systems for a grocery store in Lithuania and to select the most efficient option based on multi-criteria decision-making methods. Three alternative glued laminated timber (glulam) structural systems—the glulam column and truss system, the glulam three-hinge frame system, and the glulam column and double-tapered beam system—were designed. The systems were evaluated against ten criteria, reflecting structural properties, cost efficiency, assembling complexity, and aesthetics. Multiple-criteria assessments by the COmplex PRoportional ASsessment (COPRAS) method and simple additive weighting (SAW) method revealed that the best-performing alternative is the glulam column and double-tapered beam system due to the lower cost of load-bearing structures, the smaller quantity of required steel details and fittings, and the highest maximum utility ratio according to serviceability limit states compared to other alternatives.

Determining the significant input parameters of a forecasting model for material resources of residential construction projects at the investment feasibility assessment stage

Any investor/developer spends considerable time to make a construction decision in analyzing various parameters, such as the building site area, height restrictions, total area, quantity of necessary materials, etc. First of all, this is due to a high level of uncertainty and the complexity of estimating costs for the initial stages of project implementation. The unavailability of detailed design data at the investment justification stage makes it impossible to conduct a sufficiently accurate assessment of the value and period of construction to make highly accurate managerial decisions. However, one of the key issues, namely determining the significant parameters that have the greatest impact on future project-related decisions, has not been studied sufficiently. This article identifies the most significant parameters that impact the future characteristics of residential buildings based on an expert assessment using the a priori ranking method. The reliability of the assessment is confirmed using the coefficient of concordance. A conclusion is provided about their applicability as the input values of a forecasting model that uses machine learning and artificial intelligence to determine various technical and economic characteristics of residential buildings.

Abstract Improving productivity in construction projects has long been a major concern, and much research has been carried out to try to ameliorate construction productivity. To this end, this study aims to improve and increase the productivity rate of flat slab formwork used in residential construction projects. A survey consisting of 150 questionnaires was undertaken to identify the factors that influence on the productivity. Based on the relative Importance Index (RII), data on eleven factors deemed to affect productivity were selected. A collection of 100 data points from various sites were utilized to develop two models. Firstly, an Artificial Neural Network (ANN) model was employed, and secondly, a parametric approach was investigated. The data were divided into two sets, with 70% of the data used for training and the remaining 30% used for testing. The models’ performance was evaluated using the Mean Squared Error (MSE) and Mean Absolute Percentage Error (MAPE) values. In the test phase, the artificial neural network model yielded an MSE value of 2.6610e−4 and a MAPE value of 4.9227, whereas the parametric model produced an MSE of 0.040 and a MAPE of 9.525. It was found that the artificial neural network model provided reliable prediction accuracy compared to the parametric model. However, the artificial neural network approach can be selected as a robust model in predicting and controlling the productivity rate in local construction projects by using the developed model based on the identified factors.
