25 May 2026: Data Centers, Starts, Housing Slumps, Safety Failures, and Contract Risk

Five signals from the construction market: Turner’s data center surge is reshaping the top contractor table, April starts are finally showing broader strength, Germany’s housing slump proves demand does not equal delivery, a deadly Philippines collapse points to broken control systems, and the Chickamauga Dam termination shows what happens when schedule decay becomes public.

01 · Contractors

Turner stays on top, but the real story is concentration

Turner held the No. 1 spot on ENR’s Top 400 Contractors list for the sixth year running, with revenue jumping from $20.2B to $28.3B in 2025. The key detail is what powered the jump: data-center work. Mortenson also surged into the top 10, while FlatironDragados debuted at No. 25 after the infrastructure merger.

Hook: The ENR list is becoming a map of who has access to the scarce labor, power, and owner demand behind the AI buildout. (Construction Dive)

02 · Starts

April finally gives the wider market something to work with

Construction starts rose 9% month over month in April to a seasonally adjusted annual rate of $1.33T, according to Dodge data reported by Construction Dive. The more interesting bit is breadth. Instead of one or two giant data-center or energy projects carrying the number, nine of Dodge’s 15 categories posted double- or triple-digit gains.

Hook: If May and June hold, the non-data-center majority of the market finally gets a tailwind. If not, the bifurcation story stays alive. (Construction Dive)

03 · Housing

Germany shows what broken viability looks like

Germany’s residential construction completions fell 18% in 2025 to 206,600 homes, the lowest level in 13 years, according to Reuters. Higher building costs and elevated interest rates are still squeezing the market. The need for housing is obvious, but the economics of delivery are still not working.

Hook: Europe’s housing problem is not just demand. It is delivery economics, and Germany is flashing red. (Reuters)

04 · Safety

The Philippines collapse is a control failure story

Reuters reported that rescuers were still searching after a building under construction collapsed in Angeles City, with four confirmed dead and 17 people still missing at the time of reporting. Investigators are looking at whether the project, approved as a nine-storey condo-hotel, was altered to include an unapproved tenth floor with a swimming pool.

Hook: A collapse like this is rarely one missed detail. It is usually a broken chain of accountability. (Reuters)

05 · Risk

The Chickamauga Dam termination is a warning about slow failure

The U.S. Army Corps of Engineers terminated Shimmick Construction’s contract for a major portion of the Chickamauga Dam lock replacement project. ENR reported that the Corps cited diligence, schedule, and deficiency issues. Shimmick said it plans to appeal, while the broader lock replacement is still targeting a 2028 operational opening.

Hook: Delay does not stay "under review" forever. Eventually it becomes claims, replacement procurement, and a public reset. (Engineering News-Record)

The thread

The market is not weak everywhere, but it is less forgiving. Data centers are pulling the top contractors upward. Starts are broadening, at least for now. Housing still breaks when the economics do not work. And when governance, scope control, inspection, and schedule recovery fail, the problem eventually leaves the dashboard and becomes public.

One practical move this week

Pick one active programme and stress-test three things: (1) what part of the backlog is truly resilient, (2) where approvals or scope changes could escape control, and (3) whether the recovery plan would still convince the owner if progress slipped another month.
