Project Overview
Corrado Construction was awarded both the DCA and ABC Awards for Construction Excellence in 2012 for the Amazon project. The building itself covered almost 23 acres and the parking lots covered 18 acres of the 76-acre property. The project included site work, underground utilities, stone base for the building pad, concrete curb and hot mix paving.
- Moved 500,000 cubic yards of soil materials.
- Imported and placed approximately 80,000 tons of graded aggregate base course.
- Installed multiple infiltration basins, bio-ponds and stormwater ponds.
- Installed over 27,000 LF of underground utilities.
- Installed over 6.5 miles of concrete curb.
- Placed approximately 30,000 tons of hot mix.
- Coordinated and cooperated with multiple contractors to maintain accessibility and progress.
- Complied and maintained erosion and sediment controls under the direct inspection of the Town of Middletown.
- The project facility was substantially completed in 8 months.
Key Challenges
Corrado worked in conjunction with Duke Realty and the Civil Engineer to develop a comprehensive construction plan that would meet the demands of the aggressive construction schedule by developing the project phasing. The phasing of the 76 acres was developed to expedite the building pad turnover to the concrete contractor and facilitate the building construction. Corrado, Duke, the Geotechnical Engineer (GTA) and the Town of Middletown worked together as construction progressed to meet the Erosion and Sediment Control needs while facilitating the building and site work in a timely fashion. Corrado performed bulk earthwork operations in double shifts to meet the building schedule. Corrado’s experience was put to the test to move a large quantity of material efficiently while, at the same time, facilitating drainage for the site.
The most challenging part of the Middletown warehouse project was a combination of the size of the project, the fast-paced schedule and the winter start. The planning that went into the project to achieve the scheduled milestone dates was critical. Every aspect of field operations, constructability, subcontractor and supplier availability needed to be scrutinized to ensure the project’s success. To that end, the project teams from all parties worked long hours to produce and execute a well-developed plan.
Working closely with its client and GTA, Corrado used on-site soil to help save both time and money for the client on this project. GTA monitored the soil conditions during the cut to fill operation and provided immediate, real-time soil conditioning directives minimizing the need for import and ultimately balancing the structural import demand for the site. Close coordination with Corrado’s subcontractors and suppliers were a major key to the successful completion of the site work.
The project had an aggressive schedule from the start: beginning in February 2012 with a goal of being substantially completed by September 2012. This schedule obviously demanded a great deal of coordination and cooperation between all trades. Although the weather was more favorable than typical winters on the East Coast, it certainly presented challenges when an area of this size was under construction. Corrado Construction’s field supervision and personnel continued to find ways to maintain site drainage, stabilize graded areas, and provide workable surfaces for all trades. Ultimately, the goals of the project were achieved.
