Advancements in Train Bridge and Underpass Construction

Salmon Arm, British Columbia, is witnessing a paradigm shift in train bridge construction with the adoption of innovative techniques such as architectural shotcrete over steel sheet piling. This method not only enhances the structural integrity and durability of the bridges but also contributes to the aesthetic appeal of the infrastructure for the Ross Street Underpass.

The Rondout Bypass Tunnel Shafts – Shotcrete Lining

The Rondout-West Branch Tunnel (RWBT), a segment of the Delaware Aqueduct (the Aqueduct), was built from 1937 to 1944 and provides about 50% of New York City’s total water supply. The tunnel is concrete lined and has a finished inside diameter of 13.5 ft (4.1 m). It is about 45 mi (72 km) in length and runs in the southeasterly direction from the Rondout to the West Branch Reservoirs.

O’Hare Plaza West Drive and Executive Garage Restoration

While infrastructure projects such as parking garages are often the last projects to be funded due to their utilitarian nature, they are important to the health of commercial properties since they are often the first impression for tenants and visitors. At O’Hare Plaza, the parking garage serves the 700,000 ft2 (65,000 m2) office complex.

The Neville Island Bridge Project

The Neville Island Bridge Rehabilitation project originally came out for bid in 2018. The bridge is located in Allegheny County, PA and within PennDOT’s District 11. In the bid package, it was noted that construction could not begin until a nesting pair of Peregrine Falcons had fledged their young, which translated to a late summer start.

Moyie Dam Repair: Back to the Future

Moyie Dam at Bonner’s Ferry in northern Idaho started initial construction just before WWII. They shut down construction during the war. After the war was over, the dam went into service in the late 1950s.

COST of Wisconsin/Gilder Center

It’s rare that a building’s design can become so immediately iconic – an attraction unto itself. Gaudi’s Sagrada Familia in Barcelona comes to mind. It is a visual feast – a sculpture that takes the shape of a building. Many architecture critics are already claiming the same for the newly opened Gilder Center at the American Museum of Natural History (AMNH) in New York City.

Roadside Slope (Portuguese)

A utilização do concreto projetado revelou-se de suma importância no processo de tratamento dos taludes ao longo das margens da rodovia SP 333, no interior do estado de São Paulo, Brasil. Essa aplicação concentrouse em uma extensão que abrange os quilômetros 337 a 385, que conectam as cidades de Marília e Assis. O emprego do concreto projetado nessa localidade representa não apenas uma escolha técnica, mas também uma resposta estratégica aos desafios apresent

Shotcrete as Roadside Slope Protection in Brazil

The use of shotcrete has proven to be of paramount importance in the treatment process of the slopes along the margins of SP 333 highway in the interior of the state of São Paulo, Brazil. This application focused on a stretch covering kilometers 337 to 385, connecting the cities of Marília and Assis. The implementation of shotcrete in this challenging location represents not only a technical choice but also a strategic response to the specific challenges presented by the slopes along this section of the highway
