About
The Al Thumama Stadium is one of eight stadiums, which have been built, renovated, or reconstructed for the FIFA World Cup in Qatar in 2022. It is located near Hamad International Airport. A joint venture between Al Jaber Engineering of Qatar and Tekfen Construction of Turkey is significantly involved in the construction work.
The architectural design, by the Chief Architect of Arab Engineering Bureau Ibrahim Jaidah, takes its inspiration from the traditional taqiyah hat, a traditional cap which is worn by men and boys across the Middle East. A 50,000 m2 (540,000 sq ft) public park will surround the stadium. The stadium has a capacity of 40,000 seats. Following the World Cup, half of the stadium’s seats will be removed and will be donated to other countries.
Project Scope
The scope is to develop LOD 400 (Level of Development 400) BIM modeling, which involves creating highly detailed 3D models with all relevant construction and manufacturing information.
- Create a detailed 3D BIM model of the Curtain Walls, Doors and Glazing, including interface coordination.
- Model individual Curtain Panels, connections, framing, fixings, and support systems in accordance with LOD 400 requirements.
- Incorporate accurate dimensions, tolerances, material properties, and surface finishes into the BIM model.
- Include relevant metadata and attributes, such as panel identification numbers, material specifications, fire ratings, and acoustic properties.
- Integrate the Curtain Panel BIM model with the overall project's BIM environment to ensure coordination and clash detection with other disciplines

Challenges
The biggest challenge in the project was the repeated design changes occurred during various stages in the project. This involves a lot of re-works in the model and shop drawing.
The solution found was to approve the BIM models prior to the start of the shop drawing and few additional coordination sessions were conducted for the smooth approval of the design and the BIM model.
Another core challenge was the inability of Revit to develop a curtain wall model to the level of detail of 400 as required by the client.
The possible modelling solution we had was brought to the client attention in the initial modelling phase and necessary approvals were taken for usage of generic models wherever required. This has brought us the benefit of lesser comments on the model submitted. For example there is no solution to model a sealant in Revit, so we used generic model to show the sealants.
Value Addition
The development of curtain wall to LOD 400 helps to identify and rectify the interference clashes, which was given the most priority. Constructability and aesthetic issues were identified and notified in the initial phase to make the adequate changes to the design wherever required.
Around 10 major constructability issues were identified and rectified, which has brought huge savings on time and money.
