What Turnagain Marine Construction does

Turnagain Marine Construction Corporation is a privately held, integrated design-build marine construction and engineering firm founded in 2014 in Anchorage, Alaska by Jason Davis and Jon Archer. The firm delivers end-to-end waterfront infrastructure for cruise lines, port authorities, municipalities, and private developers under its proprietary END² methodology, which collapses concept development, engineering, and construction under a single accountable partner. Active project sizes disclosed as of 2023 range from $25M to $176M per engagement, with landmark references including Norwegian Cruise Line Holdings' Whittier destination, Huna Totem Corporation's Icy Strait Point, Ward Cove Cruise Dock, and municipal port projects for the City of Seward, City and Borough of Sitka, and City of Kodiak.

The firm's underlying technology stack is physical and process-oriented rather than software-defined: a fleet of purpose-built construction crane barges, proprietary marine foundation equipment capable of installing battered-drilled shafts up to 300 feet, and a commissioned 300-ton crane operated remotely from over 2,000 feet away to install piling and drilled shafts in challenging conditions. In 2022 the firm internalized design engineering, becoming a fully integrated design-builder. END² is a registered trademark and is positioned against traditional design-bid-build delivery, which the firm cites as producing 36% longer timelines and design-related change orders that inflate total project cost by more than 15%.

Turnagain generates revenue through project-based, single-source design-build contracts with firm pricing established during the END² validation phase prior to full design commitment. Go-to-market is sales-led and relationship-driven: clients are acquired through direct relationships, industry reputation, and best-value procurement competitions, with 84% of business coming from repeat customers and referrals as of 2023 and a 100% win rate on best-value design-build procurements in primary markets. Distribution is entirely direct, anchored in Alaska and now extending into the Caribbean via a Fort Lauderdale regional office opened in May 2024. The firm has no disclosed external institutional investment, parent company, or public listing.
