In the context of rapid urbanisation in China, demolition and forced eviction have been used by Chinese governments as urban development strategies to get rid of old, dilapidated properties while paving the way for new developments. Yet it has been argued that the impact of such forced eviction on different groups of people may vary widely, with compensation and improved living conditions for some and complete loss of shelter for others. The latter is especially true when demolition targets so-called "illegal housing," which is often mostly occupied by migrant tenants. This paper will analyse the differences in rehousing choices between groups of migrant tenants. The first section of the paper will analyse the Chinese government's policy of demolition targeted at rental housing. The second section will focus on the differential impact that demolition has had on the livelihoods of two groups of migrant tenants – the high-skilled and subsequently more resilient, and the low-skilled and subsequently more vulnerable. The final section will discuss the serious shortcomings of the current demolition policy, which fails to distinguish between these groups. The government must try to create policies to address the varying degrees of needs and vulnerabilities of the tenants it proposes to displace. Instead of a homogenous policy, this essay argues that policies should be carefully devised to accommodate different migrant tenants' needs and situations.

Construction and demolition waste (C&DW) represents one of the EU's largest waste streams. Eurostat (2010) estimates a C&DW generation of 970 Mton/year in the EU-27 (±2 ton/inhabitant), with an average recovery rate of 47% [1]. To reach a higher recycling rate, higher-purity material streams from C&D works are required. These can be obtained by a better sorting at the source, i.e. selective demolition. We performed 5 demolition case studies in Flanders to assess the opportunities and challenges of selective demolition processes, both on industrial and residential buildings. Furthermore, a new quality management and traceability system, developed by Flemish construction confederation VCB, was tested in 3 of these case studies. This monitoring system aims at the certification of waste streams that originate from selective demolition. For the different case studies, different bottlenecks and best practices were defined. In these case studies, the selectivity of the demolition is driven by the economic incentives of the Flemish market (high landfill fees and differential gate fees at recycling plants) and obligations from Flemish/Belgian legislation (e.g. mandatory elimination of asbestos and other hazardous materials). These incentives make "semi-selective demolition" current practice in the Flemish region. We define semi-selective demolition as a demolition work where the demolition company selectively collects all hazardous substances and that part of the non-hazardous substances that would overly reduce the quality of the stony fraction. The selective collection of the latter is determined by their value, the acceptance policy of the crushing installations of the stony fraction and by the time consumed for selective removal.

Màster universitari en Estudis Avançats en Arquitectura: Contemporary Project ; The Presó Model de Barcelona is destinated to be closed in the year of 2017. However, except of being known as the oldest prison in Catalunya, the prison has also been a symbol of political repression of Catalan people. This master thesis consists of both theoretical and practical parts. The former researches the political repression cases, as well as meaning and intention of monument; while the latter one is an exercise on adapting the theory to transform the Presó Model de Barcelona. Through a series of demolitions and the concomitants, the previous symbol of repression will not only become a place of commemorate; moreover, a symbol of Catalan people's collective will, intection, and manifesto for their long awaited dawn- the independence.
