CASE STUDY #2 (DOCTORS WITHOUT BORDERS)

Doctors without borders, harnessing a new donor segment for an established humanitarian organization.

Challenge Doctors Without Borders is an independent humanitarian organization that delivers emergency medical aid to people in need worldwide. DWB_USA, in collaboration with the Columbia University Strategic Communications Masters program, sought a messaging plan that would appeal to a younger segment of potential donors.

Insight Qualitative, quantitative, and desk research supported targeting an audience of international travelers, who are inclined to care about people in need in faraway places and give to international humanitarian non-profits if they can be assured that their contributions will be put to good use.

Solution We created a campaign built around the heroes of DWB: the doctors. Research revealed that donors are interested in the compelling stories of the doctors, and that an American audience responds to an upbeat message. Our final delivery clarified a younger target audience, delivered engaging new creative, and created a channel architecture plan with a way to capture metrics.

Maintenance approaches using 3d scanning point cloud visualization, and bim+ data management: a case study of dahei mountain buildings.

1. Introduction

2. materials and methods, 2.1. mapping of guanyin pavilion, 2.1.1. laser data acquisition, 2.1.2. point cloud registration of neighboring sites, 2.1.3. 3d scanning, 2.1.4. study of the existing spatial condition, 2.2. dynamic management of data in tangwang palace, 2.2.1. representation of architectural elements, 2.2.2. succession of previous maintenance information, 2.2.3. information exchange and assessment, 3.1. 3d laser scanning and point cloud registration of guanyin pavilion, 3.1.1. point cloud data, 3.1.2. data preprocessing, 3.1.3. model construction, 3.2. dynamic data management of the tangwang palace, 3.2.1. management of building components, 3.2.2. management of building complexes, 4. discussion, 4.1. application of 3d laser scanning and point cloud registration technology in guanyin pavilion, 4.2. dynamic data management of tangwang palace, 5. conclusions.

• By utilizing high-precision 3D laser scanning and point cloud registration technology, the overall structural model of Guanyin Pavilion was controlled within an error range of ±1 mm. Tilt monitoring data showed that the average tilt angle of the Tongtian Column was 0.4635°, with a maximum of 0.7892° and a minimum of 0.2115°. Additionally, point cloud data analysis revealed that the relative error in key structures such as columns and beams was within ±10 mm. Based on this data, it can be concluded that despite years of environmental exposure, Guanyin Pavilion remains structurally stable. However, minor tilting and dimensional changes in certain parts require regular monitoring and maintenance.
• On the GIS platform, the building elements of Tangwang Palace were meticulously documented, and the maintenance history of 1974, 1982, and 2000 reconstructed. By examining this maintenance information, we found that certain building elements repeatedly exhibited issues and were repaired, indicating long-term structural weaknesses in these areas. The roof tiles, mentioned repeatedly in the maintenance records of 1974 and 2000, showed signs of loosening and detachment. Despite repairs during each maintenance cycle, the problem persisted, suggesting potential design or material deficiencies in the roof structure. Records show that the wooden beams experienced corrosion and breakage in multiple maintenance cycles. Particularly in the 1982 and 2000 repairs, the restoration of wooden beams was a significant focus, indicating that the beams are highly susceptible to environmental influences and require special attention to protective measures. Wall cracks were noted in the maintenance records of 1974 and 1982, primarily on the building’s south wall. Despite multiple fillings and reinforcements, the cracks persisted, potentially due to foundation settlement or material aging. BIM excels in targeted management by accurately documenting and tracking individual building components, including comprehensive analyses of deterioration patterns and the effectiveness of specific restoration measures. When integrated, BIM and GIS combine spatial data with detailed architectural information, providing a comprehensive and dynamic tool for heritage conservation. This integration enhances decision-making accuracy regarding maintenance priorities and resource allocation by leveraging GIS’s spatial visualization and BIM’s component-level data management.
