Full 20-Column Concrete & Steel Audit
Surveyed As-Built Geometry vs Design Clear Heights vs Fabricated Columns
Critical Clash Audit: Pedestals are cast with severe radial eccentricity ($1,601 ext{ mm}$ maximum deviation) and uneven levels up to $+65 ext{ mm}$ above FFL. While G.A. drawings specified custom clear heights ($5209$ to $5449 ext{ mm}$) to adapt, the shop drawings detailed all 9 pieces of COL-10 to a single uniform length of 5,384 mm, guaranteeing major erection failure if not re-detailed.

Executive Project Overview
Fusion Developers was commissioned to conduct the architectural review, 3D Building Information Modeling (BIM) synthesis, and structural engineering audit for the Albarakah 165 ft ($50.16 ext{ m}$) Clear-Span Circular Marquee Pavilion. The structure encloses an unobstructed 21,382 sq.ft ($1,986.5 ext{ m}^2$) grand ballroom utilizing a 20-bay radial Pre-Engineered Building (PEB) skeleton crowned by a central $5.58 ext{ m}$ diameter compression hub (`Ring-1`) at an apex clear height of $+9,117 ext{ mm}$.

Critical Engineering Finding & Hold Directive
While the architectural spatial geometry and primary 5-segment rafter design are brilliantly conceived, our forensic survey audit identified that the site concrete pedestals were cast out-of-round with a massive 1,601 mm ($5.25 ext{ ft}$) radial eccentricity and elevation errors up to +65 mm. Furthermore, the fabrication shop detailed all 9 perimeter columns (`COL-10`) to an identical length of $5,384 ext{ mm}$, which directly clashes with the site conditions.
Architectural & Engineering Verdict: Steel erection must remain on HOLD until the 3-step civil & shop rectification protocol detailed in this dossier is executed.
Execution Roadmap for Client Delivery
1
Level Concrete Pedestals
Chisel down high concrete pedestals (Grids 2 & 3) to achieve a uniform Finished Floor Level ($\pm 3 ext{mm}$).
2
Re-Detail COL-10 Columns
Release revised shop cutting cards for the 9 `COL-10` pieces matching the true leveled elevations.
3
Central Shoring & Apex Stubs
Erect Ring-1 on temporary central tower at $+9,117 ext{mm}$ and field-cut the apex stubs to guarantee pure radial thrust equilibrium.
