墨西哥·伊斯塔卡尔科INFONAVIT住宅区

INFONAVIT伊斯塔卡尔科住宅区是该机构于1972年建成的首个住宅项目。该社区位于墨西哥城东部的伊斯塔卡尔科区（该地区建城历史已达700年），最初围绕一个人工湖规划建设。然而，1979年地震导致土壤开裂危及湖区安全，人工湖最终被排干。25年后，市政府将场地改造为如今的"湖畔公园"，其核心构筑物由混凝土柱支撑的半球形钢架结构组成，跨度约500平方米。由于施工缺陷，该结构的不规则几何形态导致部分区域结构完整性受损，穹顶始终未能完工。在随后的岁月里，场地逐渐荒废，混凝土平台和裸露的钢框架在风雨侵蚀下历经二十载日渐破败。

The UH INFONAVIT Iztacalco Complex was the first housing development built by the institute in 1972. Located in Iztacalco, in the eastern sector of Mexico City—an area that celebrates 700 years since its founding—it originally centered around an artificial lake. However, after the 1979 earthquake, soil fissures compromised the lake, leading to its drainage. Twenty-five years later, the city government transformed the site into what is now "Parque del Lago", featuring a central structure composed of concrete columns supporting a semi-spherical steel framework spanning approximately 500 m². Due to construction deficiencies, the irregular geometry of the structure resulted in sections that compromised its structural integrity, leaving the dome incomplete. Over time, the site was abandoned, and both the concrete platform and the exposed steel framework deteriorated under the elements for two decades.

2024年，墨西哥国家工人住房基金会（INFONAVIT）发起了一项公开招标竞赛，旨在征集住宅区中央公共空间的活化改造方案，内容涵盖设计、管理和工程干预等多个维度。其中最具挑战性的设计要求是：为半圆形钢结构加装围护体系，使其下方空间能够遮阳避雨。

In 2024, INFONAVIT launched an open-call competition for a design, management, and intervention proposal aimed at revitalizing the central common area of the housing complex. One of the most challenging requirements was to enclose the semi-sphere to protect the space beneath from sun and rain.

在赢得竞赛后，设计团队立即启动了跨政府部门的复杂协调工作。经过约800万比索的投资和四个月的施工周期——这一高效资源管理的实证——半圆形结构现已加装功能性顶棚。通过景观营造、色彩规划和建筑手法等多维改造，INFONAVIT伊斯塔卡尔科住宅区的核心区域重焕生机。新建成的公共空间包含：260平方米的带顶棚活动广场、社交休闲桌椅区、专业跑酷场地以及广受欢迎的街头健身区。

Upon winning the competition, the team initiated a complex coordination process involving multiple government agencies. After an investment of approximately eight million pesos and four months of construction—a testament to the project's efficient resource management—the semi-sphere now has a functional roof. Additionally, the heart of the UH INFONAVIT Iztacalco Complex has been revitalized with landscape, chromatic, and tectonic interventions. The new public space includes a 260 m² covered forum, tables for socializing and relaxation, a designated parkour area, and a popular calisthenics workout zone.

在这片焕发新生的活动场域中，12米高的半圆形穹顶结构成为战略性屋顶系统的视觉焦点——全新设计的遮阳体系为社区集会提供了更舒适的荫蔽空间。改造方案还融入了细腻的色彩策略：明快的色调与原先占据主导的灰色混凝土形成鲜明对比。新建的论坛广场与加固后的穹顶结构采用暖色调染色混凝土，而蓝绿色钢构支架支撑着波纹金属面板，共同构成充满动感的多元色彩界面。

At the center of these new activities, the 12-meter-high semi-sphere became the focal point for a strategic new roofing system, designed to provide enhanced shade for community gatherings. The intervention also integrates a sensitive approach to color, with vibrant hues contrasting against the previously dominant gray concrete. The new forum and reinforced dome structure feature pigmented concrete in warm tones, while turquoise-green steel structures support corrugated metal panels in a dynamic, polychromatic finish.

为满足竞赛对半圆形穹顶覆盖的设计要求，该方案创新性地采用了柱基与钢结构节点加固技术。通过悬索支撑的倾斜屋面系统——由钢制网格框架与轻质金属板材构成，辅以高强度钢缆固定——实现了"以最少材料创造最大空间效益"的设计理念。这一解决方案不仅高效利用资源，完美契合INFONAVIT的既定目标，更通过极具张力的建筑语汇，重塑了场地的空间特质。

To address the competition’s requirement of covering the semi-sphere, the proposal included structural reinforcements at the column bases and steel joints. A suspended, inclined roof system—formed by a steel grid and lightweight metal sheets—was secured with tensile steel cables. This solution optimized resources by covering the space with minimal material yet maximum impact, successfully meeting INFONAVIT’s objectives while enhancing the site’s architectural character.

该项目彰显了公共投资对墨西哥城住宅区带来的变革潜力。精心设计的干预措施植根于资源效率和战略规划，可以振兴公共区域，将其转变为聚会、娱乐、学习和社区参与的空间。这些改进为居民提供了锻炼和邻里互动的机会，增强了归属感和社会凝聚力。最终，该项目表明，巨额预算并非总是必要的——最重要的是精心规划、管理和精心设计的公共投资策略，它能够为公共空间注入新的活力，并增强墨西哥城住宅社区的社会结构。

This project exemplifies the transformative potential of public investment in Mexico City’s housing complexes. Thoughtfully designed interventions, rooted in resource efficiency and strategic planning, can revitalize common areas—turning them into spaces for gathering, recreation, learning, and community engagement. These improvements provide residents with opportunities for exercise and neighborhood interaction, fostering a sense of belonging and social cohesion. Ultimately, this project demonstrates that large budgets are not always necessary—what matters most is a well-planned, well-managed, and well-designed public investment strategy that breathes new life into communal spaces and strengthens the social fabric of Mexico City’s housing communities.
