This building, symbol of the long term and visible presence of EDF in the Meuse and Haute Marne region, hosts the company’s industrial records. Within the framework of the Meuse and Haute Marne economic support programme, EDF has decided to centralise all its intermediary Engineering Production Management archives in Bure-Saudron. Until now, these paper copy archives had been stored in nuclear, hydraulic and thermal production units, as well as in engineering units and associated services.
The new centre allows the documents’ organisation and it also ameliorates the storage and the utilisation processes. These archives, on paper-based and microfilm-based formats, will occupy about 70 km of shelves. The building has also a laboratory for micro-films, specifically designed for this purpose.
The architects realised a five level, 19 m high building within a plot of 3.30 hectares comprehensive of an archives area covering approximately 1,400 m2 and a total surface of approximately 7,000 m2.
An archives storage building needs to have a considerable inertia with a minimal exchange with its external setting. The need for fast and simple site management and optimum storage efficiency led us to develop a simple and rational layout. The building is divided into 2 programmes: archives and offices. The archives’ part is composed by 20 storehouses of 200 m2 each; with regulated temperature and hygrometry. The blocks can resist fire for 2 hours and they are equipped with a sprinkling system. The offices’ part is N/W oriented, embedded in a natural slope planted with trees and plants. The offices have an ideal view on the surrounding landscape.
Tree-planted surfaces give some advantages: from an ecological point of view the trees protect the building against climatic issues. From an aesthetical point of view – and within an idea of landscape integration – they complete the building by inserting a pattern recurring from the landscape: the “merlons”, narrow strips of land planted with hardwoods. The project of the landscape foresees the framing of the views from the offices by planting vegetable masses. Some framings already exist from the highway in the project’s direction. A game of sequences is set in combination with the architectural plan in order to vary the visuals and to put an accent on the building’s continuity with its landscape.
The elevations will incorporate a total of 120,000 stainless steel studs. Stainless steel studs (7 cm diameter and 1 mm thick) will be incorporated into the formwork during the casting of the integrally coloured prefabricated concrete elevation panels. The panels will be 15.65 m high and either 2.26 m or 2.33 m wide depending on whether they are on the long or short side of the building. The 8 cm thick panels will be reinforced with concrete ribbing (+ 7 cm). The complex will be suspended from reinforced concrete walls and held in position using distancing jacks. The elevations will have a total thickness of 68 cm. The facade’s building process was the subject of a patent.
