    Noise Solver for Refurbishment Construction Site Design

    Get PDF
    The noise generated by the presence of a construction site within complex structure in operation (e.g. school, hospital) is a problem that too often is underestimated but that can generate problems of different nature, both concerning the health of the actors involved and regarding the performance of daily activities present within such structures (e.g. carrying out a lesson, a surgical procedure). The main aim of our tool is to highlight the impact of the noise generated by the construction site activities on these daily activities and to allow the simulation in real time of the viable solutions, thus arriving to find the one that is considered most suitable

    Dect architecture proposal for a construction site

    A construction site is an specific environment where important propagation related issues have to be considered. In particular an important problem concerns the coverage of buildings under construction and therefore continuously changing. The deployment of a DECT system in such scenarios can not be carried out as usually, by means of DECT base stations linked by cables. Another specific problem is that no measures can be done prior to decide the best place for the antennas since initially the building does not exist. In this paper a way to solve both problems is proposed through a specific system architecture, a propagation model and a combination of software with a CAD tool.Peer ReviewedPostprint (published version

    Sediment traps from synthetic construction site stormwater runoff by grassed filter strip

    Sediment trapping of the synthetic construction site stormwater runoff (SCSSR) by grassed filter strip (GFS) was studied in a laboratory flume with simulated GFS of different slopes and bed surface areas. The polynomial regression model of average rainfall density depended rainfall duration has been approved by Malaysian Storm Water Management Manual. Still the relationship between either storm-water runoff flow rate or sediment trapping efficiency and rainfall duration needs to be verified. This study proposes the use of the empirical equations to determine the SCSSR flow rate and to estimate the efficiency of the GFS models to trap sediment based on the rainfall duration. All the parameters in equations have physical meanings, and experimental data validation showed that the equations are suf-ficiently accurate. The stormwater runoff flow rate and efficiency of the GFS models were verified for the SCSSR originally coming from a construction site of Kuala Lumpur city. New approaches to investigate the hydrological behaviour of construction site are presented and have significant implications for the ability of stormwater flow to carry sediment

    Principles of Management Application in Building Construction Projects: Perspectives of Project Managers’

    Get PDF
    One of the most crucial factors to consider when setting up and managing organizational activities is the application of management principles. Most of the time, organizational failure is attributed to either as a violation of management principles or an organization's inability to establish this precedent in the running of its day-to-day activities. This paper, therefore, focused on the application of the management principles of Henri Fayol in the management of human resources for construction projects. The study utilized a descriptive design using a survey study and explorative design through a literature search. Relevant literature was reviewed to identify management principles for the design of the questionnaire. The population is the core building professionals working as project managers in a construction site of three tertiary institutions in Bauchi. Forty-five (45) questionnaires were distributed and successfully filled and retrieved. SPSS software was used for the analysis. The study used descriptive statistics and the Kruskal-Wallis test for the analysis. The results show that the majority of the respondents (80 %) acknowledged the importance of these principles to the construction industry in the management of human resources in the construction site. Also, the findings revealed that project managers always used most of these principles in the management of human resources in the construction site. Although, lack of planning and motivation, non-adherence to principles and standards, clashes of interest and corruption revealed as top challenges of its implementation on construction site. The finding concludes that the more the respondent works longer on construction sites, the higher the application of these principles in managing human resources on sites

    Occupational safety and health practice: a study at Infrastructure construction work

    Safety is the state of being “safe”, the condition of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, educational or other types of consequences of failure, damage, error, accidents, harm or any other event which could be considered non-desirable. Health is a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity. In that case, Occupational Safety and Health Act (OSHA) is an act that ensure the well-being of workers in a broad scope of many specialized fields. This study is focused on the construction of a police headquarters located in Seriab, Perlis. A big number of construction companies in Malaysia might not perform safety practice for their workers, lack of safety appliances, and did not perform a regular safety check-up on their workers as the reason was they want to earn more profits and they took the safety measures of their foreign workers for granted. Note that most of construction workers in Malaysia are immigrants. The data collection was carried out through site investigation using Preliminary Hazard analysis (PHA), HIRARC form and interview session with a worker in the construction site. The objective of this study is to spread the awareness of the importance of safety among workers in the construction site based on the existing potential hazards. This report was initially to identify the hazard on the construction site and to analyse the occupational safety and health factor in the workplace. The results are to analyse and suggest recommendations for improving occupational safety and health act in the construction site. Practicing a good safety measures in the workplace will ensure the well-being of workers

    Hazard identification, risk assessment and risk control: a study at construction site

    Get PDF
    Occupational Safety and Health Act (OSHA) is an Act to make further provisions for securing the safety, health and welfare of persons at work, for protecting others against risks to safety or health in connection with the activities of persons at work, to establish the National Council for Occupational Safety and Health, and for matters connected therewith. This study focuses on infrastructure construction in Pagoh Education Hub. In present days, despite of knowledge in OSHA act, workers often proceed the work without considering any safety precaution or act at workplace as stated in OSHA Act. Due to ignorance of workers and employee on OSHA Act, workers are exposed to danger and hazard at their workplace causing them minor or worst fatal injury. The data collection was carried out through site investigation using Preliminary Hazard Analysis (PHA), HIRARC form and interview session with several workers in the constructio. The main objective of this study is to support the idea to coordinate and redefined the practice of occupational safety and health as workers discipline at their workplace based on existing potential hazard. This study was conducted to identify the hazard that occur at the workplace and analyse the safety precaution taken by the workers and employer to avoid accidents. As a result, this study listed several suggestions to improve the practice of occupational safety and health among workers in the workplace
