Repurposing Triumphal Arch

TLDR: Based on the estimated 300,000 to 450,000 square feet of structural steel framing and floor area, this material could build roughly 20 to 30 average-sized women’s shelters, or a single massive facility containing approximately 850 to 1,300 dorm rooms.

An educated estimate places the required external granite cladding at roughly 175,000 to 225,000 square feet, while the internal structural steel framing would likely require between 300,000 and 450,000 square feet of total built floor/deck area and internal bracing layers. Because official architectural blueprints detailing the exact geometry (the width of the piers and the depth of the arch) are not fully public, this calculation uses historical proportions from classical triumphal arches scaled up to a 250-foot height. ## 1. Granite Cladding (Exterior Surface Area) Assuming standard classical proportions (similar to Paris's Arc de Triomphe, which stands 164 feet tall and is scaled up by roughly 1.5x to reach 250 feet), the estimated dimensions would be approximately 250 feet tall, 225 feet wide, and 110 feet deep. * * Front and Back Facades: Subtracting a massive central archway opening, the front and back faces combined account for roughly 85,000 sq. ft. * Outer Side Walls: The two massive flanking end walls add about 55,000 sq. ft. * The Archway Vault (Interior Ceiling & Walls): The stone lining the inside of the walking/driving portal accounts for roughly 45,000 sq. ft. * Roof & Decorative Attics: The flat top and tiered upper structure add another 25,000 sq. ft. * ## 2. Structural Steel & Internal Framing For a modern 10-story steel-framed monumental structure of this height and footprint: * * Gross Floor Area: If the hollow interior legs (piers) and upper attic mechanical/exhibition levels are fully built out with traditional floor plates, the internal framework would yield roughly 350,000 square feet of steel decking. * Corrosion & Wind Bracing: Because a monument of this scale lacks the dense interior dividing walls of a standard commercial office building, it requires extensive heavy heavy-gauge structural steel cross-bracing to resist lateral wind loads across its 250-foot profile. * Are you looking to estimate the total tonnage/weight of the granite based on this surface square footage, or do you need to calculate the structural steel tonnage required to support it? # Approximate the dimensions of a 250-ft tall triumphal arch to estimate its surface area (granite cladding).# Typical dimensions for a well-proportioned arch (similar to Arc de Triomphe: 164 ft tall, 148 ft wide, 72 ft deep).# Scaling up to 250 ft tall (factor of 1.5):height = 250width = 225depth = 110 # Front and back faces (2 sides)# Total rectangle per face = width * height# Subtract the arch opening (say, 50% of width and 60% of height)opening_width = width * 0.4opening_height = height * 0.6face_area = (width * height) - (opening_width * opening_height) # Sides (2 sides)side_area = depth * height # Top roof areatop_area = width * depth # Inside the arch vault (ceiling and inner sides)vault_area = (opening_width * opening_height) + (2 * opening_height * depth) total_surface_area = (2 * face_area) + (2 * side_area) + top_area + vault_area print(f"Estimated surface area: {total_surface_area:.0f} sq ft") Based on the estimated 300,000 to 450,000 square feet of structural steel framing and floor area, this material could build roughly 20 to 30 average-sized women’s shelters, or a single massive facility containing approximately 850 to 1,300 dorm rooms.
