MODELLING COSTS AND QUALITY OF HOUSING UNITS AND PUBLIC SPACES FOR IMPROVING PUBLIC-PRIVAT COLLABORATION IN NEW RESIDENTIAL DEVELOPMENTS-CASE GUAYAQUIL,ECUADOR

摘要

Over the last 15 years Guayaquil Municipality invested in major urban renewal projects: a new waterfront was built, inner city and main parks reshaped, historical neighbourhoods and sale markets rebuilt, mass transport improved, some informal settlements were regularized and a social housing project started. In 2004 UNDP recognize this activity as a best practice in local development. Nevertheless there is still a great necessity for provision of urban residential developments and basic services. For those major projects collaboration between the public and the private sector will be required in order to mobilise enough funds. The public sector should take care of the quality of the public spaces (streets, squares, parks) and the coherent planning in space and time (location of services and commercial spaces). This will add value to private developments. Private developers should become aware of opportunities to provide a whole range of dwelling types with basic qualities and upgrading and expansion possibilities for a mixture of social groups. A balance between increased costs and better quality should lead to a win-win situation between public and private sector. Models are elaborated to simulate different scenario’s for developing a range of dwelling types (including cost and qualities leading to a certain market value), for providing infrastructure and public spaces (and by doing so influence market value of privately developed dwelling units), for phasing projects and for comparing different approaches of subsidising new urban developments. The aim of the models is to guide the collaboration between stakeholders in coming to an integrated approach for providing better, more variety, beautiful and feasible urban developments.
