The summary of the results of the survey
The absence of quality in the results of the urban improvement work especially on the environmental quality ;
The inexistence of coordination between the various actors generating a discordance between their various actions ;
A restricted operational culture towards the great operations that include the urban improvement work on
public space
, also, with the logic of the great operations.
Not equity
Discomfort and insecurity
Management and maintenance
Traces of urban overlay are limited to substrates of the
Arabo- Turkish
period taking the shape of “
TRADITIONAL TOWN

Nowadays
, most of squares have disappeared and some of them are neglected. New cities, like
ALI MENDJELI
, were built according to a new planning principles and a new way of producing the city
what is the proper manner to reconquer these public spaces through sustainable urban vision ?

In the
French
era with its “
COLONIAL CITY
”, the public space of the old city of Constantine is based on the hierarchy of spaces: from the private space (home) to the public space (squares…)

It seems that the majority of public spaces (when they exist) are inaccessible

Public spaces are far away from the places of residence. The distance represent the principal cause.34% of the surveyed mentioned that the access is difficult to these spaces.

Green spaces and gardens represent most attended public spaces by surveyed persons. They feel comfortable in this type of public space, but, it should be noted that 21,3% did not answer affirming that they feel comfortable only in their houses.

Security constitutes a precondition to the use of these spaces by the surveyed persons Changing mentalities, taking in charge the urban space and ensuring animation, they become more attractive so the actions of appropriation can be done by citizens .
Proposals and suggestions
ENERGY AND CLIMATE
Supporting an adequate urban planning, energy effectiveness by taking in consideration topography, orientation and green species (contextualization)
CLIMATE AND ENERGY
A good water management processes makes it possible to decrease the extension of the networks and the building oversizing
DISPLACEMENT
Developing public spaces which support means of soft transport
POLLUTED SOILS AND SITES
Reinvest spaces in wasteland (evident depollution)
NOISES AND HARMFUL EFFECTS
Taking into account sound dimension in the installations and materials used for the horizontal and vertical coatings
RISKS
Preserving the sectors with strong ecological value (slopes, wooded surfaces...) and to take into account the exposed areas to the various risks (flood, update…)
WASTE
Optimizing installations to facilitate and to improve the collection of waste
BIODIVERSITY AND LANDSCAPES
Conceiving green spaces, giving them a function and an ecological maintenance procedures
PROJECT MANAGEMENT AND MANAGEMENT
Providing control of work (supervision and services decentralized of the state) with managers specialized in the management of public spaces who master an important requirements all around the 10 field of project management
Conclusion
Initially the causes of the destruction of the Algerian public space are related to the country’s history especially colonization. Today, the lack in managing public spaces is essentially linked to political choices: first, all the government's efforts are focused on how to solve the problem of the housing crisis, secondly, the threat of public space for authorities if it should play its full role in the establishment of a democratic state. So the urban improvement operations done by the authorities do not meet the expectations of citizens and their results are not satisfactory. The will to control the movement of population and the absence of communication project management between the citizens and the authorities (project main stakholders) constitutes the main obstacle to produce suitable urban space. Moreover, these barriers can be overcome if the management of such projects is based on the application of the 10 fields of project management.
