Enhancing knowledge exchange through web map-based knowledge management system in construction: Lessons learned in Taiwan

Knowledge management involves creating, securing, coordinating, combining, retrieving and distributing knowledge. Knowledge can be reused and shared among engineers and experts to enhance construction processes and decrease the time and cost of solving problems. This study presents a novel and practical method to capture and represent construction project knowledge by using network knowledge maps. Network Knowledge Maps (NKM) gives users an overview of available and missing knowledge in core project areas, enabling tacit and explicit knowledge to be managed appropriately. This study addresses application of knowledge management in the construction phase of construction projects, and presents a construction Map-based Knowledge Management (MBKM) concept and system for contractors. The MBKM system is then utilized in selected case studies involving a High-Tech factory building enterprise in Taiwan to verify the proposed methodology and indicate the effectiveness of sharing knowledge, particularly in the construction phase. Knowledge can be captured and managed to benefit future projects by effectively utilizing information and web technologies during the construction phase of a project. The results of this study demonstrate that an MBKM-like system can be applied effectively in knowledge management systems in the construction industry by using map-based knowledge management and web technology.

Evaluations of existing waste recycling methods: A Hong Kong study

Environmental problems have been considered as a serious situation in Hong Kong construction. Waste management is pressing harder with the alarming signal warning the industry. Reuse, recycling and reducing the wastes are considered as the only methods to recover the wastes generated; however, the implementations still have much room for improvement. In order to ameliorate the existing situations, evaluations of the existing waste recycling methods are studied in this research. A telephone interviewing to the recyclers, site visits to the construction and demolition sites (including the Lower Ngau Tau Kok Estate Phase 1) and the centralized recycling plant in Tuen Mun Area 38 are under investigation. Difficulties encountered for various recycling parties are investigated. Rather than the poor quality found from the recyclable materials, they found the high investment cost, lengthy demolition period and limited space caused the major barriers for them. Therefore, some recommendations are suggested: (i) proposing a higher landfill charging scheme; (ii) setting up a centralized centre for recycling the materials; (iii) examining the Hong Kong government should be supported in the provision of land for recycling plants; (iv) implementing innovative demolition methods; (v) allowing some locations in town for residents’ easy access to drop-off recyclable materials; (vi) allowing flexible demolition periods; (vii) setting up recycling plant in town or in the form of mobile installations; (viii) reusing the reusable components as donations to the charity organization; (ix) providing higher flexibility in receiving concrete waste in Tuen Mun Area 38 recycling plant; and (x) balancing the supply and demand of recycled materials through legislations or incentive schemes.
