Construction firms and environmental groups see the benefits of using nonpotable water at construction sites, but any effort to do so is stymied by regulatory hurdles. A commission has been assembled to study the problem and develop potential solutions.
Amtrak has selected Riverside Investment & Development for the $1 billion redevelopment of Union Station in Chicago, which will take place in phases and involve renovation of the Great Hall and Headhouse and construction of two residential and two office towers, plus a mixed-use tower. The project will develop 3.1 million square feet of space, and work may take up to six years.
Kiewit Construction has started the excavation and demolition work needed at the Oroville Dam in California, the preliminary step to repairing the spillway. Officials want the spillway functional by November, and crews hope to soon place concrete for the spillway's foundation.
The May Architecture Billings Index increased for the third straight month and hit 50.9. The index, which gauges future construction spending, saw a slight decline in multifamily housing.
Almost 30 years after the Loma Prieta quake, earthquake resistance improvements at the Golden Gate Bridge are only partially complete. Two reasons the job is taking so long are the challenge in securing $600 million to pay for it and the necessity of custom design and building of enormous shock absorbers.
Democratic leaders soundly rejected President Donald Trump's proposed $1 trillion infrastructure plan, which includes $200 billion in public investment over 10 years.

US energy systems and infrastructure are grappling with an increasing number of cybersecurity threats despite oil and natural gas companies' and the Transportation Security Administration's best efforts to strengthen protections. "There appears to be an increasing level of activity, sophistication and maturity of threat actors, in particular nation state actors, that wish to disrupt the U.S. bulk power system and the U.S. gas transmission or distribution system," Dominion Energy said in a filing with the Securities and Exchange Commission.
The Federal Transit Administration says it hasn't rejected funding for the Purple Line light-rail project in Maryland, even though the project doesn't yet have a signed full funding grant agreement. That signed agreement is a prerequisite for federal funding, according to the Trump administration.
Projects by Mortenson Construction, McCarthy Building Cos. and DPR Construction demonstrate what can be accomplished with connected technology on construction sites. Compliance, worker safety and rapidly changing environments can all be enhanced.
The Delaware Department of Transportation and the University of Delaware collaborated on the design and construction of a bridge replacement, and the work led to the use of a geosynthetic reinforced soil integrated bridge system. "The new bridge is basically a composite bridge structure that incorporates GRS abutments and prefabricated bridge superstructure elements," said Christopher Meehan, the civil engineering chair at the university.
