Robotics is one of the advanced technologies that is used in various aspects of the construction industry to improve the efficiency and the performance of construction projects. The adoption of construction robotics technologies is significant strategies to maintain and improve productivity in the construction industry. Even though the implementation of construction robotics technologies can improve productivity, many Malaysian contractors do not embrace the existence of robotic technology and still practicing the traditional method due to many challenges. Therefore, the objectives of the study were to investigate the challenges of the implementation of construction robotics technologies in the Malaysian construction industry and the improvement method. The data of the research were achieved through a quantitative method, which questionnaires were distributed to 180 G7 contractors in Kuala Lumpur. Subsequently, 50 valid responses were retrieved and the collected data were analysed using Statistical Package for Social Science (SPSS). The findings revealed that the two (2) main challenges of the implementation of construction robotics in Malaysia were the high cost to maintain and update process the technologies. The finding also showed that strategic partnership with a high technology company was the best method to improve robotics implementation. In conclusion, this study is believed to be useful information in improving the implementation of robotics technologies in construction projects particularly around Klang Valley.

Dredged sediment can be used in producing bricks for geotechnical engineering purposes including construction of foundations, retaining walls and roads. This study was conducted to determine the strength of brick made from dredged sediments and comparing them with the strength of normal brick. This study was conducted in an experimental form that involves collecting dredged sediment in the river of Sungai Bebar, Pahang, Malaysia and the river of Sungai Setiawan, Perak, Malaysia for analysis. It also involved the use of materials and equipment from laboratory to test the strength of brick. The results obtained from the analysis of data showed that the strength of brick exceeded the standard value for ordinary brick in Malaysia’s standard. This support the fact that the brick made from dredged sediment can be used in Malaysian construction industry. The result of this study helps to reduce the volume of dredged sediment to be disposed and to avoid geo-hazards from dredging activities.

Sea and river dredging has produced a large volume of dredged waste over the years which could trigger geo-hazards including dispersion of contamination from sediments. One of the ways to overcome this issue is by incorporating it into geotechnical engineering purposes including the production of concrete for foundation, retaining wall and highway construction. This research aims to investigate the strength of concrete made from dredged sediments and to compare it with the strength of conventional concrete. This research emphasises on the usage of two types of dredge waste; silt and sand, obtained from Kuala Perlis, Perlis and Sungai Bebar, Pahang, respectively. The dredged sediments from Sungai Bebar will be used as fine aggregates while sediments from Kuala Perlis will be used as admixtures and fine aggregates for production of concrete. The concrete will then be tested for its strength. As a result, the concrete made from these two rivers are able to produce the minimum strength requirement for C20 concrete mix. This enables the concrete mixtures used in this research to be applied in the construction of foundation, retaining wall and highway. This research helps in reducing the amount of wastage from dredge work as well as providing a new material source for concrete.

Currently, the most severe infectious disease was the new coronavirus disease (COVID-19) in all countries in 2019 and 2020. At the end of December 2019, in Wuhan, China, there was an international cluster of cases involving Novel Coronavirus pneumonia (SARS-COV-2). The worldwide number of active cases and deaths is rising, especially in the top countries such as the United States (U.S), Brazil, and India. In Malaysia, these cases of COVID-19 have significantly decreased the number of active infections and deaths in May and June 2020. COVID-19 has had a significant effect on human life, socio-economic growth, and public relation. It is aimed at senior groups and individuals with various health conditions such as cancer, respiratory problems, diabetes, hypertension, and heart-related issues. The World Health Organization (WHO) has formally declared COVID-19 as an international emergency case. As a result, Kuala Lumpur was the most affected state in Malaysia as of 12 July 2020, followed by Selangor, Negeri Sembilan, and Johor. Regardless of the infection chain ratio, the favorable cases in each affected state of Malaysia are rising every day. The Malaysian Government attempted to split the infection chain ratio affected by COVID-19 via the lockdown definition. The research aims to use GIS software to analyze COVID-19's spatial trend distribution and temporal pattern analysis for human health. Geographic information systems (GIS) technologies have played a significant role in spatial information, spatial tracking of confirmed cases, active case, death, and discharge cases, and predicting the magnitude of the spread. Monitoring, evaluating, and planning using geospatial analysis are essential for controlling the spread of COVID-19 within the country.
