Clark joined Washington Metropolitan Area Transit Authority (WMATA) in celebrating a significant milestone in the construction of the WMATA Northern Bus Garage as we begin erecting the facility’s steel structure. 🚍
With the completion of concrete foundations, the advancement of slab-on-grade placement across the bus storage level, and underground plumbing and electrical installation, crews are starting to erect the steel structure that will house WMATA’s next-generation bus fleet. #ClarkBuildsDC
DID YOU KNOW: When runway construction began at DFW Airport in 1972, the contract for three million yards of concrete was the world's largest! 🚧 🛫
Enough concrete and asphalt were used on the runways and roads to pave a four-lane expressway from Dallas to Oklahoma City. #TBT#DFW50
A beautiful sunrise greets the #OHLAUSA project team as they start their workday at the Montebello Corridor Grade Separation project in Montebello, California. This contract is one of several Grade Separation procurements that OHLA USA has performed for the San Gabriel Valley Council of Governments.
The project, which was awarded in 2023, calls for the construction of a bridge at the Union Pacific Railroad crossings at Montebello Boulevard and Olympic Boulevard, creating a roadway underpass at both locations. The contract will eliminate potential train collisions with vehicles since motorists will travel below grade while trains traverse the track unimpeded. The effort will also significantly reduce traffic congestion and emissions and enhance safety by upgrading signal systems and adding pedestrian crossings.
Located eight miles east of downtown Los Angeles, the grade separation requires the demolition and excavation of substructure elements followed by the construction of a steel girder bridge with concrete fascia and earth retaining structures. Also included is the installation of CIDH piles, abutments, and columns. To advance the project, the OHLA USA team will grade and prepare the site within the Union Pacific Railroad right of way, construct support of excavation systems, build roadway structural sections, and construct a temporary track detour to allow trains to remain operational through the construction zone. Extensive paving activities and concrete work for curbing, gutters, and sidewalks are also part of the contract.

Custom drums. They have so many applications for concrete and can be made in a variety of different shapes and sizes. But what does the process look like, and how do things work start to finish? Here's a quick look at how customer PCiRoads went through the process:
The Challenge: Minneapolis is booming with growth, but its century-old storm drain system was feeling the strain. With cracks and breaks, it needed a major overhaul to keep up with the city's hustle and bustle.
The Search: PCiRoads 30-person crew was tasked with installing about 4,200 feet of new tunnel with a total of around 15,000 cubic yards of new concrete. Estimator and project manager, Nap Scott, knew the amount of concrete involved and the complexity of working far below the streets of downtown would require a unique solution. Knowing a stock solution wouldn't cut it, Mike Clover, PCiRoads concrete superintendent, searched for a more user-friendly, efficient method to shape the concrete.
Innovation at Work: Clover reached out to us and laid out their required specs — a drum with a 13-inch drop for the tunnel floor that could only extend out a few inches because of the tunnel walls. They also would require a way to finish the concrete after the custom drum shaped it. Drawings of the custom system were sent, and once approved we built the equipment.
The Results: After testing the equipment and making sure it could be safely transferred underground, the real job began. With our custom equipment and PCi's skilled team, workers were able to complete the job quicker, with higher efficiency and a healthier environment.
Join the Concrete Revolution: With the multitude of possibilities custom drums provide, the future of construction is brighter than ever. Let's keep building, one project at a time!

A giant cantilever structure, used in the UK for the first time, has built the first section of our 472 metre River Tame West Viaducts.
The structure has been built, using a 22-metre-high mast, including temporary post-tensioning cable stays and a 14-metre-high swivel crane. The crane lifts and installs one concrete segment into place at a time, eventually completing each 45-metre span length.
The permanent post-tensioning tendons are then stressed to allow the removal of the temporary cable stays, leaving the permanent structure securely in place. The same process is repeated between each pier until all the spans are complete.
