Project management contract Loi MOP, and study contract, relating to the urban renewal of the Picon-Busserine district, 13014 Marseille, FRANCE.
As part of the project for the urban renewal of the Picon-Busserine district, and the L2 cover project, the GPV of the City of Marseille instructed the urban planning team Babel, a Prado workshop, SOGREAH, to draw up a guide plan for the development of the district, which would lead to requalification measures: demolition, new construction, rehabilitation (which may lead to thickening of buildings and housing restructuring), residentialisation.
The urban renewal project is structured around 3 ideas that meet the objectives of revitalising, opening up and enhancing the value of the Saint-Barthélémy-Picon-Busserine neighbourhoods: prioritising urban routes and practices, giving the neighbourhood an identity, removing the traces of the L2. 3 ideas that take three structural urban forms (attached plan):
— a main track, with the grouping of shops, equipment and housing along the east to west, along a route,
— the sports district, or the consolidation on a North/South axis of land and equipment dedicated to sport,
— the urban park that ‘descends’ the hill in the neighbourhood and connects Busserine, Picon and Font Vert. In doing so, the project is part of the geography of the hill and valley, taking into account hydrology, biodiversity and the plant world from a sustainable perspective.
As the project perimeter is very wide, physically halved by the railway, it is divided into 2 large study areas, each with different urban and architectural issues.
The urban renewal project involves the carrying out of concurrent construction, rehabilitation, demolition and residentialisation operations, which include:
construction of collective housing in each of the 2 sectors: 40 to 60 on Picon – 40 to 60 on Busserine. On Picon, the aim is to build a housing island along rue Cade, the architecture and gauge of which will make it possible to ensure the continuity of the urban fabric, as well as a small housing unit opposite the E building, which will have to fit smoothly into the heart of the island consisting of buildings E, B, D and F. Sur Busserine, the aim is to build denser housing units between 3 and 8 levels, allowing for the construction of forty to around sixty dwellings. These constructions will lead to a densification of the sector. The architectural issue will relate to the composition of the volumes and the treatment of the facades of these housing units. These construction operations for social rental must meet the following objectives:
Affirm the link between the neighbourhood and its environment.
Integrate the very pressing hydraulic constraints on the neighbourhood.
Improve the vial service frame,
Improve the readability of public/private spaces.
Reinvest stranded spaces.
— the rehabilitation of 257 dwellings (buildings B D E F G) in the Picon sector, and the rehabilitation of 375 dwellings (buildings L M Q J) in the Busserine sector. The extension into façades of the M, J and B buildings is envisaged,
— residential housing in each sector, with the construction of an underground car park on the Busserine sector,
demolition of 330 housing units by 2012 (outside the scope of these project management contracts).
These operations must be accompanied by consultation meetings and workshops with the inhabitants, which are essential for the success of the project. The institutions are stakeholders in the project. In addition to regularly informing about the content and progress of the operations carried out as part of the studies and the monitoring of the works, the project management will involve the services of the State, the City of Marseille and MPM for the coordination of works.
The contracting authority’s expectations on these projects are as follows:
Define a high-quality architectural project forming part of the site in the light of the location and volume recommendations defined by the urban planner.
Design an efficient envelope (winter, summer thermal) to control rental charges for new construction and rehabilitation.
Optimise construction costs, particularly in view of the low level of exit rents.
Optimising the cost of VRD: define efficient rainwater management arrangements.
Obtain a BBC effinergy and H – E certification issued by cerqual for all new buildings.
Integrate into the organisation of the team the constraints of coordinating the studies and work carried out on the whole urban project, with the L2 and RU projects, intervention in a living environment, and consultation with residents.
Quality of monitoring of the works and unqualified acceptance before the accommodation is delivered.
Finally, it is specified that the obligation to undertake work is set by the ANRU by 31.12.2013 at the latest.
