Con Dig (04-Sep-26) — A strong US construction cycle is led by the start of a $1 billion-plus Western transmission project, a $481 million airport-infrastructure grant round and new federal facilities work. Data-center and prefab-manufacturing developments also feature prominently.
$1B-plus Southwest Intertie transmission project breaks ground
Great Basin Transmission, an LS Power affiliate, has broken ground on the Southwest Intertie Project-North, a 285-mile, 500 kV transmission line connecting the Midpoint Substation near Twin Falls, Idaho, with the Robinson Summit Substation near Ely, Nevada. LS Power said the project represents an investment of more than $1 billion and is intended to improve grid reliability, reduce congestion and move more electricity across the western US.
Why it matters: This is a major new linear-infrastructure start with substantial civil, electrical and transmission-construction scope across two states.

Navy awards $200M roofing construction vehicle across Southwest
Five contractors have been selected for a combined $200 million multiple-award IDIQ covering new construction, renovation and repair of roofing projects at Navy installations. Most work will be performed in California, with additional scope in Arizona, Nevada, Utah, Colorado and New Mexico, and the contract runs through September 2034.
Why it matters: The award establishes a long-duration pipeline of recurring federal facilities work across a large regional footprint.
Grose wins $24.5M depot facilities construction contract
Grose Construction LLC has been awarded a $24.5 million firm-fixed-price IDIQ for small construction, repair and modernization projects at depot buildings and facilities. Work locations and funding will be set with individual task orders, with the contract scheduled to run through September 2031.
Why it matters: The contract adds another identifiable federal facilities pipeline and should generate multiple task-order opportunities over five years.
Clark Pacific starts 110-acre Arizona prefab plant
Clark Pacific has broken ground on a new manufacturing plant in Coolidge, Arizona, that will ultimately span 110 acres. The company said the project will be built in phases, with final completion scheduled for spring 2027, and will triple its production capacity for prefabricated building systems.
Why it matters: The plant expands industrialized construction capacity serving sectors including data centers, parking structures and advanced manufacturing facilities.

Meta’s $1.2B Kuna data center goes online
Meta said its Kuna, Idaho, data center is now operational after construction that supported up to 1,600 skilled trade workers. The company has invested more than $1.2 billion in the project and more than $100 million in a new local water and wastewater system built to support future growth.
Why it matters: The milestone closes out a major hyperscale build while also highlighting the municipal infrastructure investment increasingly required around large data-center campuses.
GSA identifies about $10B in future federal building work
The General Services Administration has transmitted 103 prospectus-level capital project fact sheets to Congress covering approximately $10 billion in projected repairs and modernization needs from fiscal 2028 through 2034. The scope includes roofing, elevators, HVAC, fire alarms, water-damage remediation, hazardous-materials work and structural, seismic, electrical and plumbing repairs.
Why it matters: While much of the work remains prospective, the package offers a significant forward view of the federal building-repair pipeline.
