Project Overview

Corrado American provided earthwork services for the expansion of the Belvedere Mine at York Building Products in Northeast, Maryland. Our services included clearing and mass grading for a 1-mile long conveyor system connecting the aggregate mine to the newly added aggregate crushing and screening plant. Additionally, CA provided mass grading and drainage improvements for the aggregate crushing and screening plant, new entranceway, and new asphalt plant.

Over 100,000 tons of stone were placed, over 185,000 CY of earthwork were moved and 2,600 tons of asphalt were placed.

Key Challenges

Some key challenges were designing and constructing a roadway across an existing wash pond and improving onsite drainage as grading occurred in an active mine. Corrado American implemented a combination of geotextiles and low ground pressure techniques to construct the road.

Project Overview

CA performed the layout and installation of 124 anchor posts for solar arrays at the Newark Reservoir. We also excavated and backfilled for the electrical conduit run from the existing transformer to the new solar equipment.

Key Challenges

The site was located in a floodplain that was especially difficult to work in after rain events, and the soil was soft and spongey. To address both challenges, Corrado American used a rolling matting system. This system provided safe and efficient access to install the posts and panels in the proper sequence.

The orientation of the solar panels and spacing of the rows within a tight site also required a high level of precision for our layout and driving of posts.

Project Overview

Corrado American provided general contracting and construction services for the first phase of the yard densification project at the Port of Wilmington located in Wilmington, Delaware. The project consisted of constructing fourteen multi-level reefer racks, expansion of the dry container storage area and infrastructure up-grades to support new gantry cranes and reefer rack system. The project also included busbar assembly and installation – the first of its kind installed in the United States.

Corrado American worked closely with the design team, busbar manufacturer, and owner to provide value engineering and design modifications to bring the project in under budget.

• Over 3 miles of electrical and communication duct bank
• Over 4,000 linear feet of concrete runway and busbar foundation
• Over 5 acres of milling and paving rehabilitation
• 3 cast in place concrete elevated electrical substations and switchgear platforms
• 32 helical pile foundations

Key Challenges

High water table/tides. The project site is located on recent marine deposits, resulting in soft ground conditions and a high water table that fluctuates with the tides. State of the art excavation support, dewatering methods and careful planning were used during foundation and utility installation.

Operational port. Corrado American phased the construction so as not to disrupt everyday operations.

Potential environmental hazards in the ground. Corrado American provided environmental oversight and followed the CMMP guidelines closely during excavation and dewatering operations.

Global pandemic. Starting and finishing work during the COVID 19 pandemic.

Field conflicts. Corrado American worked closely with the design team to provide design alternatives and solutions to address field conflicts discovered during the project.
