架构师提供的文本描述。拉瓦尔大学的科学大楼，帕维隆亚历山大-瓦肯，于1962年落成.经过50年的使用，没有做任何重大的工作，这座45，000平方米的建筑需要一次大的整容和彻底的大修。这座展馆是由建筑师卢西安·曼盖伊设计的，他是魁北克现代主义运动中的重要人物，由大学委员会负责保护和维护拉瓦尔大学的建筑遗产。该大学提出了一项耗资9 000万美元的分阶段翻修项目，最初的投资为1 800万美元。

Text description provided by the architects. Laval University’s science building, the Pavillon Alexandre-Vachon, was inaugurated in 1962. After fifty years of use without any significant work done to it, the 45,000 m2 building was in need of a major facelift and complete overhaul. Designed by architect Lucien Mainguy, an important figure in Quebec’s modernist movement, the pavilion is protected by the CAMEO, a university committee that among other things is mandated to protect and maintain Laval University’s architectural heritage. A $90 million phased renovation project was put forward by the university, starting with an initial $18 million investment.

翻新-保护

Renovation – conservation

帕维隆-亚历山大-瓦肯改造的双重目标因此是保护和升级。尽管其体积构成具有巨大的建筑质量，但科学建筑却严重缺乏功能性。这个项目的第一阶段需要应对的主要挑战是几乎不存在的游说、迷宫式的流通、陈旧的学生空间和缺乏普及的机会。

The dual aim of the Pavillon Alexandre-Vachon renovation was therefore conservation and upgrading. Despite the tremendous architectural qualities of its volumetric composition, the science building was seriously lacking in functionality. An almost inexistent lobby, maze-like circulation, obsolete student spaces and deficient universal access were the main challenges that needed addressing by the first phase of the project.

Unification

大楼的核心设施包括一个新的大厅、新的垂直循环、自助餐厅和新的学生会室，以使大楼在第一阶段立即发挥更大的作用。这一空间是通过在旧的内部庭院上建造一个屋顶而创建的，该庭院的西面一直延伸到主停车场。与新餐厅相连的大堂使用户能够通过一部新电梯和连接大楼两翼的走道系统直接进入大楼的所有区域，而在翻修之前，这些通道是相互隔离的。

Creating a core for the building including a new lobby, new vertical circulation, cafeteria and new student association rooms were factored in to make the building immediately more functional in the first phase. This space was created with the construction of a roof over the old interior courtyard whose west façade opened out onto the main parking area. The lobby connected to the new cafeteria enables users to directly access all areas of the building by means of a new elevator and a system of walkways linking the building’s wings, which prior to the renovation were isolated from each other.

使用体系结构来满足结构需求

Using architecture to meet the structural needs

所选择的体系结构方法受到结构需求的强烈影响。鉴于原建筑结构支撑的重大缺陷，新的中庭必须是独立的，完全独立于原来的结构。六根25米长的柱子分布在五个树枝上，在30个均匀分布的点上为屋顶提供支撑。还讨论了中央空间的自然光和声学特性。一个巨大的玻璃隔墙在西侧的中庭，天空的灯光围绕着屋顶的外围和白色的墙壁使得人工照明几乎是可选的。除西墙外，中庭周围的所有墙都是由穿孔的复合板构成的，其后面安装了吸收垫。考虑到空间的类型，这为新餐厅提供了令人印象深刻的音质。

The chosen architectural approach was strongly influenced by structural requirements. Given the significant shortcomings of the original building’s structural support, the new atrium had to be free standing and completely independent from the original structure. Six 25 metre columns spreading into five branches provide support to the roof at thirty evenly distributed points. The natural light and acoustic qualities of the central space were also addressed. An immense glassed partition on the west side of the atrium, a sky light around the roof’s periphery and the white walls made artificial lighting almost optional. All the walls around the atrium aside from the west wall are made of perforated composite panels behind which absorbent cushions were installed. This provided the new cafeteria with an impressive acoustic quality, considering the type of space.

该建筑物的外部也进行了翻修，以符合原来的建筑。简单的体积和充分考虑的比例充分融合了新的补充到原来的建筑物。竖立在柱子上的装有教室的机翼被修复，而不是翻新。因此，外部遮阳和内部装修几乎完全保持不变，尽管完全升级的机翼。该项目的后续阶段将纳入与第一阶段相同的养护、升级、功能改进和提高用户舒适度的目标。

The building’s exterior was also renovated in keeping with the original architecture. Simple volumes and well considered proportions fully integrate the new addition to the original building. The wing containing the classrooms, which is raised up on columns, was restored rather than renovated. As such the exterior sun shades and interior finishes were almost completely kept intact despite a complete upgrade of the wing. Subsequent phases of the project will incorporate the same objectives of conservation, upgrading, functional improvement and enhanced user comfort as the first phase.
