3D reality mesh of 216 sqkm of the Al Jumah District generated with ContextCapture.
Documenting Significant Historical Landmarks By using ContextCapture and Orbit, AHCEC was able to document each historical spot in the city using realistic and detailed models. These models were used to help develop new roads through the city, superimposing other models on the reality model so designers and engineers could see everything accurately and clearly laid out. The model captured every feature of the highly congested area, including trees and the texture of the buildings. Even narrow, dark alleys were modeled in great detail with a combination of laser scanning and photogrammetry. The team also implemented data from existing point clouds. The model provided a single location where the multidiscipline site planning and engineering teams could find in- formation that they needed. It is now easy to share the models with other departments, as well as visualize and measure without having much experience in 2D or 3D modeling. Lastly, the team conducted a feasibility study for a 3-kilometer walkway between two important mosques, as well as conduct shading analyses to allow for maximum walking comfort between the mosques and surrounding facilities. Creating a Solid Foundation for Future Projects Reality modeling provided the team with a reliable survey technique that minimized modeling time and costs while streamlining decision-making and visualization. AHCEC’s reality model helped the team complete the project 15 months ahead of schedule while still creating a design that facilitates pilgrim access to Al-Madinah. Using Context- Capture and Orbit, the project team completed the objective in nine months, saving over a year in surveying time and more than SAR 42 million. The team captured more than 750,000 images, modeled 41,672 buildings, and surveyed more than 7,000 kilometers of roads in high definition. This project was the first of its scale in Saudi Arabia to use consumer UAVs in such a short timeframe. Moving forward, the teamwill use Bentley’s iTwin® Services to create a digital twin. AHCEC plans to collect information from utilities, in- cluding environmental sensors, to add to the reality model. The team plans to implement AssetWise and ProjectWise, creating a single source for all project information that can be contained in the reality model.
