Alaska Engineering Standards

Structural Engineering Specific to Juneau

Roof Snow Load
70 – 100 psf ground snow load

Every building manufactured for Juneau is engineered for localized snow accumulation, drifting, and unbalanced loads according to local borough code amendments.

Wind Design Rating
110 – 125 mph design wind (Taku wind events)

Framing members, secondary purlins, wall girts, and fastener schedules are engineered to resist local wind shear and uplift forces common across City and Borough of Juneau.

Seismic Design
Category D / High Seismic

Varco Pruden solid-web steel frames feature heavy bolted moment connections designed to absorb seismic ground motion without brittle failure.

Climate Classification
Climate Zone 7 (Maritime Rain & Snow)

High-performance continuous thermal envelope options, including Varco Pruden insulated metal panels (IMPs), ensure minimal heating fuel costs during subzero periods.

Freight & Delivery to Juneau

No road connection. Freight shipped via barge (Alaska Marine Lines / AML) from Seattle or via AMHS ferry from Haines/Skagway/Bellingham directly into Juneau harbor.

Packaging Guarantee: Every building package is bundled, sequenced, and tagged with complete hardware packing lists so your project proceeds without missing parts on the jobsite.

Foundation & Site Preparation

High water tables, marine muskeg, or steep bedrock slopes. Foundation requires site-specific civil engineering, pile driving, or rock-anchor tiebacks.

Anchor Bolt Drawings: Prior to building delivery, Superstructures provides stamped anchor bolt setting plans with reaction loads so your foundation contractor can pour with total confidence.

Local Questions Answered

Frequently Asked Questions About Building in Juneau

How do you get a steel building to Juneau without road access?+
Materials are bundled, containerized, or flat-racked at our Pacific Northwest staging facility in Seattle/Tacoma and barged directly into Juneau via Alaska Marine Lines (AML) or Samson Tug & Barge.
How do Taku winds affect building engineering in Juneau?+
Taku winds produce sudden, hurricane-force wind shears cascading off the Juneau Icefield. We engineer framing, siding, and roof clips for 120+ mph wind loads with reinforced fastener patterns.
What prevents condensation in Juneau's wet rainforest climate?+
We specify continuous vapor-barrier insulation systems and Varco Pruden insulated metal panels that eliminate cold surface contact and stop condensation from forming inside the building.
