- Abstract
The method of increasing the capacity and avoiding excavation of waste materials as part of the final closure of uncontrolled landfills with the use of a reinforced earth embankment of adequate height is described. The case of the Syros uncontrolled landfill (Cyclades islands, Greece) is presented, where the method was applied. The design principles are detailed along with the method of analysis, the analysis results, the construction specifications and finally the construction method that was used. PDF |

- Abstract
During the winter of 2001-2002, a landslide of 80.000 m3 was activated and moved downslope at the Northeast outskirts of the Pissouri village in Cyprus (Limassol prefecture), displacing a section of a country road that was crossing the upper part of the sliding mass and destroying three newly built residences. This paper presents the geologic and hydrogeologic regime of the landslide and its implication on the landslide’s mobilization. Geotechnical site investigation and post failure monitoring, in conjunction with slope stability back analysis formed the basis for the study of the slide and subsequently guided the remediation strategy. Various possible interventions to stabilize the slope and allow the safe reconstruction of the displaced road have been investigated and compared considering both economic and environmental criteria. The performance of the remediation measures has been studied in terms of stability safety, using numerical models previously calibrated via back analyses. Observations made during the execution of the stabilization works provided additional data verifying and supplementing the original design. PDF |

- Assessment of different construction and demolition waste management approaches

- Description
- The waste generated from construction and demolition sites is considered one of the most irritating problems in Egypt. In the last 10 years some effort has been made toward solving this problem, the most outstanding is the newly issued Egyptian rating system “Green Pyramids Rating System”. It emphasizes on waste management and particularly “site provision and environment” which contributes to 75% of the management category score. However the traditional practice which is limited to dumping all the generated waste is still dominating. The absence of sustainable practices in construction sector in Egypt led to the lack in financial and environmental data. From strategic perspective, the research aims at developing a detailed procedure to evaluate two construction and demolition waste management approaches by means of Decision Matrix technique. A detailed study is introduced for the two approaches; for each approach a flow chart is developed to demonstrate its lifecycle, as well as the cost break down structure and the different stakeholders’ roles. A penetration discussion of the pros and cons for each approach was developed accordingly and came out with sixteen influencing attributes for both approaches. The previous steps paved the ground to construct a Decision Matrix to decide on one of the approaches from a strategic environmentally oriented perspective. The study relied on the detailed and deep demonstration of the two approaches to justify the assigned weight for attributes and scores for corresponding approach. From a strategic perspective, the decision came out in favor of the more environmentally friendly approach.
