Con Dig (29-Sep-26)
Construction Dig Morning Briefing
The biggest US construction developments from the past 24 hours, led by a proposed $15 billion Iowa steel complex, a $169 million Fort Worth flood-control award and fresh infrastructure, data-center and housing activity.
$15bn Iowa steel complex targets 2030 production
Mesabi Metallics plans a $15 billion steelmaking complex in Iowa, with first-phase capacity of 7.5 million tons per year and expansion potential to about 10 million tons. The White House said the project could support up to 6,000 construction jobs, with iron ore supplied from Mesabi’s newly opened Minnesota operation.
Why it matters: At this scale, the project would rank among the largest industrial construction investments in the US and create major demand for contractors, equipment, concrete, steel and supporting infrastructure.
Walsh lands $169m Fort Worth flood-control contract
The US Army Corps of Engineers has awarded Walsh Construction Company II a $169.4 million contract to build the North Bypass Channel for Fort Worth’s Modified Central City flood-risk project. The roughly 3,900-foot channel is expected to enter initial earthmoving in late winter or early spring 2027, with completion targeted for 2029.
Why it matters: The award moves a major component of Fort Worth’s long-running Central City program into construction and creates a sizeable civil earthworks package.
Fairport Harbor dredging backlog gets $39m contract
The Army Corps’ Buffalo District awarded Walsh Service Solutions a $39.3 million contract for dredging at Fairport Harbor, Ohio, addressing a 1.3 million-cubic-yard backlog. Work will run across three construction seasons from 2027 through 2029.
Why it matters: The project restores capacity at a Great Lakes freight gateway handling about 1.8 million tons of cargo annually.
Mississippi secures $44m for DeSoto County road capacity
Mississippi has secured a $44 million federal INFRA award for roadway and traffic-system improvements in fast-growing DeSoto County. The funding is intended to advance a capacity project on an important freight corridor and reduce congestion.
Why it matters: The award adds another federally backed highway package to the pipeline in one of Mississippi’s key logistics and growth areas.
New Mexico data-center developer strikes union construction pact
Green Data Centers and the New Mexico Building and Construction Trades Council have agreed a framework for the developer’s planned New Mexico projects. The model calls for local union labor alongside on-site solar, battery storage and water-generation systems intended to reduce pressure on public power and water infrastructure.
Why it matters: Data-center permitting is increasingly being shaped by power, water and workforce concerns; the agreement offers one model for developers trying to win local support for large campuses.
Stibnite critical-minerals project advances early construction
Perpetua Resources said early works are progressing at its Stibnite Gold Project in central Idaho, including the Burntlog access route, worker housing and transmission-line infrastructure. The company secured federal approvals in 2025 and has continued critical-path construction through the summer and fall.
Why it matters: Stibnite is a significant US critical-minerals development, bringing road, power, accommodation and mine-site construction into a remote Idaho location.
$110m St Petersburg housing project breaks ground
Metro Development Group and Porter Development have started the first phase of Azalea Cay on the former Raytheon property in west St Petersburg, Florida. The roughly $110 million first phase will deliver 341 apartments, including 102 income-restricted units, as part of a planned three-phase community of around 1,000 homes.
Why it matters: The start converts a long-vacant industrial property into one of the larger multifamily developments currently moving ahead in the Tampa Bay region.
Milwaukee advances one-year data-center construction pause
Milwaukee’s City Plan Commission unanimously backed a proposed one-year moratorium on new data-center development while officials develop new regulatory and zoning rules. The measure reflects growing municipal scrutiny of the land, power and infrastructure demands associated with AI-driven construction.
Why it matters: Local regulation is becoming a material development risk for the US data-center boom, potentially affecting site selection and construction schedules well beyond Wisconsin.
What we’re watching
The Iowa steel announcement is the clear lead today. Construction Dig will also watch for contractor selection, site and schedule detail around the project, while the Fort Worth channel award is a strong addition to the US civil-project pipeline.
