The high organic content of peat soil significantly affects its structural characteristics, leading to low shear strength and high compressibility, causing serious building problems, such as settlement or structural instability. Using unsustainable, costly materials within conventional methods for stabilisation has propelled interest in sustainable alternatives. Accordingly, this study aims to investigate the feasibility of using sustainable stabilizers, by-product gypsum and concrete waste, to enhance the structural and mineralogical properties of peat soil. Analytical tests, including SEM, EDX, XRD, and FTIR tests were conducted to evaluate the effectiveness of these stabilizing materials. The results demonstrated that the stabilized peat soil exhibited a denser, more cohesive soil matrix with improved particle bonding and reduced pore gaps. Crystalline phases of quartz and kaolinite were also observed, contributing to increased strength and reduced compressibility. Additionally, a notable reduction in organic content and an increase in stabilizing components like sulphur and calcium were identified. These findings highlight the potential of this approach as a cost-effective and environmentally sustainable solution for addressing the challenges associated with peatlands in construction practices.

On June 5th, 2015, the Ranau region experienced a notable seismic event with a magnitude, Mw 6.1. Hence, seismic designs shall be implemented to mitigate damage to structures, particularly in Sabah. The seismic designs increased the required steel reinforcement, which elevated the cost estimations of the building models. Therefore, this research investigated the impact of seismic designs on cost estimation at varying values of the reference peak ground acceleration (PGA), αgR. Phase 1 encompassed analysing and designing a non-seismic model of an irregularly 12-story reinforced concrete (RC), square-shaped residential building model utilising Tekla Structural Designer 2024 software followed by Eurocodes 1 and 2 (2004). Meanwhile, the details of the gravitational and wind actions were specified in the Malaysian National Annex to Eurocode 1 (2010) and the Malaysian Code of Practice on Wind Loading (2002), respectively. Phase 2 involved the re-analysed and re-designed to incorporate seismic provisions of Soil Type B and values of the reference PGA, αgR = 0.08g, 0.12g, and 0.16g, as outlined in Eurocode 8 (2004) and the Malaysian National Annex to Eurocode 8 (2017). Phase 3 calculated the take-off concrete volume, required steel reinforcement, and formwork area by comparing the seismic designs to the non-seismic building models. Thus, this study provided detailed information on cost estimations for the construction parties to construct a secure medium-rise irregularly building models during earthquakes, especially on 12-story building models. The results demonstrated that seismic designs increased the total estimation costs by −1.37% to 11.61% for PGA values, αgR, of 0.08g, 0.12g, and 0.16g, respectively.

The scarcity of suitable land for development has led to the exploration of challenging terrains such as tidal mangrove swamps for construction. This study examines a mixed-use development project in the Manjung District of Perak, Malaysia, where the site is underlain by deep soft peat and marine clay, posing significant geotechnical challenges, particularly excessive post-construction settlement. This study aims to evaluate the effectiveness of the Bamboo-Geotextile Buoyant System (GEOBAMTILE) in mitigating post-construction settlement and providing a reliable solution for construction over soft ground. The GEOBAMTILE system was implemented based on its cost-effectiveness and successful track record. Settlement data were collected using instrumentation installed across different site areas—both GEOBAMTILE-treated and untreated zones, such as playgrounds and high-rise buildings. The data were analyzed and compared to assess settlement performance, with the results interpreted using Hetenyi’s Beam on Elastic Foundation Theory and empirical observations. The results indicate that the GEOBAMTILE system significantly reduces post-construction settlement compared to untreated areas. The settlement in treated zones stabilized within 200 days, whereas untreated areas exhibited continuous settlement, demonstrating the effectiveness of the system in minimizing differential and total settlements. The study confirms that the GEOBAMTILE system offers a viable and cost-effective solution for construction over soft ground by leveraging the buoyancy and load-distributing properties of bamboo-geotextile composite structures. The findings support the potential for broader application of this technique in similar geotechnical conditions.

Like all other fast-growing lower- income countries, Bangladesh is also experiencing rapid urban growth and fast construction is a dire need. The Global trend of utilizing shipping containers for construction in Bangladesh also follows the trend. Bangladesh has abundant used shipping containers due to export-import through major seaports and strategic geographical locations. Recycled shipping containers are mostly used for commercial, retail, and business purposes rather than residential use in our contexts. However, studies focusing on shipping containers in lower- income countries are limited. Some Research focuses on an economic perspective and others based on sustainability. However, studies on the design aspects of shipping containers for commercial purposes are rare.This research examines the potential use of shipping containers for commercial purposes, focusing on the Design Statement, Modularity, Eco-friendly features, Customization, Cost-effectiveness, Renewable resources, Thermal Performance, and Strength. We seek to contrast conventional views and reveal new insights into their viability for larger-scale implementation through the case study of three commercial projects in Dhaka through a mixed-method approach. Systematic observation of spatial layout during field and questionnaire surveys was conducted to collect data. The results were analysed through inferential statistical analysis of the questionnaire data and comparative analysis of the observation data. This research will help architects and engineers comprehend the design scope using shipping containers for the fast-expanding construction market.

Prevention through Design (PtD) is one of the practices to reduce the risk of construction accidents. The objective of PtD is to ensure that safety and health concerns are considered as early as in the design stage, involving all stakeholders from client to contractor. In Malaysia, the PtD concept is known as OSHCI(M). However, previous studies have shown that not all stakeholders willingly cooperate in the application of the PtD concept, resulting in unsuccessful risk reduction. Some stakeholders still believe the conventional method works well because the application of PtD will only cost money and time. Therefore, this study was carried out to determine the level of awareness among construction stakeholders in OSHCI(M) implementation. A quantitative approach was adopted for this research, utilizing a survey design. This study highlights the potential of survey-based research in capturing stakeholder awareness and perceptions, providing valuable insights into the implementation of safety practices within the construction sector. A structured questionnaire served as the primary instrument for data collection, focusing on the perceptions of seven (7) key stakeholders: client, architect, quantity surveyor, C&S engineer, M&E engineer, Safety and Health Officer (SHO), and contractor. The questionnaire consisted of four (4) sections (concept, duties, principles, and risk reduction) with statements evaluated using a Likert scale. The findings indicate that all construction stakeholders are either aware or highly aware of OSHCI(M) as part of the PtD concept. This demonstrates that the stakeholders in the Malaysian construction industry have a strong level of awareness and understanding of OSHCI(M), highlighting the effectiveness of efforts to expose them to this safety and health initiative.

As solar energy becomes crucial for sustainable architecture, elevated temperatures hinder the efficiency of photovoltaic (PV) systems. The absorption of solar radiation causes a significant rise in temperature, which negatively impacts the electrical efficiency of PV cells. This study aims to develop a prototype of a Smart Cooling System (SCS) tailored for rooftop solar panels in green building applications. A 50W solar panel was mounted on a mild steel stand at a 45° tilt angle. The flow rate and water pump speed were controlled using an Arduino Uno R3, adjusting based on the PV panel’s temperature. Experiments were conducted both with and without water cooling. Without cooling, the panel reached high temperatures, resulting in an efficiency of only 7.5%. In contrast, under water cooling conditions, the temperature dropped by as much as 10°C, leading to a 35% increase in solar cell efficiency compared to the uncooled state. This research highlights the potential of smart technologies to enhance the performance of renewable energy systems in green buildings, contributing to more sustainable urban environments.

Rapidly evolving of the construction industry in Malaysia is due to advancement in technology and growing demand for efficient and sustainable practices, including Geospatial Building Information Modelling (GeoBIM). It integrates geospatial data with Building Information Modelling (BIM) to improve planning, design, construction, and management of building projects. However, implementing GeoBIM in Malaysia’s construction industry faces several challenges including data interoperability, accuracy of 3D models and integration of different data sources. GeoBIM offers a major step forward from traditional methods by combining GIS and BIM for better project management and decision-making. Unlike traditional approaches, which rely on static data and siloed processes, GeoBIM provides a dynamic platform for collaboration, 3D visualization and realtime insights, making it a game-changer for modern construction. Ironically, the practicality of GeoBIM is relatively low and vague. This study aims to identify the knowledge and acceptance level of GeoBIM technology among construction companies in Pahang, Malaysia. The relevant factors contributing to the acceptance of GeoBIM by the construction industry was investigated. A mixed-method approach is employed by utilizing both qualitative and quantitative data collection techniques. Primary data is collected through surveys targeting BIM experts in the AEC industry. Secondary data comes from a comprehensive literature review of journal articles, government policies, and industry publications. GIS-based Analytical Hierarchy Process (AHP) is used to analyze the data obtained from interviews and questionnaires. This study found that the Malaysian construction industry lags in technology due to a lack of investment in skills of GeoBIM. It provides valuable insights into the current state of GeoBIM adoption in Malaysia and resolve all challenges associated with its implementation. The government needs to enforce and promote the use of modern construction technologies also contributes to developing strategies that promote the integration of innovative technologies in construction, thereby supporting Malaysia’s commitment to sustainable urban development and resilient infrastructure, in line with SDG 9 and SDG 11. With these SDG, it can enable efficient urban development, resources optimization, disaster risk management and sustainable building design. By providing data-driven insights, GeoBIM promotes low-carbon development, resilient infrastructure, and inclusive public services, ensuring smarter, greener, and safer urban environments.

The construction and demolition (C&D) sector in Malaysia contribute significantly to economic growth but also faces challenges related to excessive waste generation and resource inefficiency at the same time. The adoption of a 10R circular economy (CE) framework emphasizing strategies such as Refuse, Reduce, Reuse, Repair, Refurbish, Remanufacture, Repurpose, Recycle, Recover, and Rethink has the potential to transform C&D waste management practices, aligning with global sustainability goals. However, implementing such a framework in Malaysian infrastructure projects is hindered by various barriers; including limited awareness, inadequate policy frameworks, high implementation costs, and resistance from industry stakeholders. Therefore, this study aims to i) identify barriers and countermeasures for implementing 10R CE for C&D of Malaysian infrastructure projects and ii) determine key barriers and countermeasures for implementing 10R CE for C&D of Malaysian infrastructure projects. At the first stage, all the barriers and countermeasures will be identified from secondary data collection. Then, the Analytical Hierarchy Process (AHP) survey is developed based on five (5) barriers and (5) countermeasures and conducted with ten (10) selected experts. Based on the outcome, there are three (3) critical barriers and two (2) critical countermeasures determined; namely i) lack of marketing strategies, ii) limited technology research and development capabilities, and iii) insufficient product competitiveness. Whereas the two (2) critical countermeasures with highest priority ranking are consisted of i) strengthening market research and marketing and ii) strengthening talent cultivation and technological innovation. This study holds significant value for the C&D sector in Malaysia as it addresses critical barriers hindering the adoption of the 10R CE framework. By exploring practical countermeasures, the research contributes to the advancement of sustainable practices, resource efficiency, and environmental stewardship within the industry. This study aligns closely with the United Nations Sustainable Development Goals (SDGs), particularly those focused on sustainable cities and communities (SDG 11), responsible consumption and production (SDG 12), and climate action (SDG 13).
