Aberdeen Army Reserve Center Stormwater Improvements

Key Accomplishments

• Installed waterstop within the concrete construction, integrating the joint-sealing system with the formwork and concrete-placement sequence to support the water-control requirements of the completed structure.
• Coordinated and set embedded items furnished by others before concrete placement, requiring the concrete formwork and embedded components to be accurately positioned and secured before the structure was poured.
• Integrated owner/contractor-furnished mechanical components into the concrete structure during construction, coordinating placement of the specified pipe segment and operating-stem valve with the forming and concrete operations so the components became part of the completed conveyance structure.
• Coordinated concrete operations with Pavex's supporting site work, while excavation, stone, fine grading, backfill and elevation layout were performed by others. This required CSD's forming and placement activities to follow the site-preparation and layout completed ahead of its concrete work.
• Performed the work under federal-project labor and safety requirements, with the subcontract package incorporating prevailing wage documentation and detailed health, safety and environmental requirements applicable to CSD's field operations.
• Concrete Services Division, LLC completed the concrete construction package associated with the Aberdeen Army Reserve Center Stormwater Improvements in Edgewood, Maryland. The federal project was performed at the Aberdeen Army Reserve Center, with Pavex, Inc. serving as CSD's contracting party for the stormwater construction work. The CSD project record identifies the work as a federal project associated with Pavex and USACE.
• CSD's primary work centered on construction of the project's conveyance cutoff structure. The subcontract required CSD to provide the supervision, labor, equipment and materials necessary for the concrete package, including forming, concrete pumping, placement and associated concrete construction activities.
• The structure incorporated waterstop and embedded components that had to be coordinated with the formwork before concrete placement. Embedded items furnished by others were set as part of CSD's work so that they would be properly incorporated into the finished concrete structure.
• CSD's work also required coordination of mechanical components passing through or incorporated into the conveyance structure. The specified pipe segment and operating-stem valve were furnished by others and positioned as part of the forming and concrete sequence, requiring coordination between the concrete work and the permanent stormwater-system components.
• The concrete package was closely coordinated with Pavex's civil work. Excavation, stone placement, fine grading, backfill and elevation layout were specifically assigned to others, allowing CSD to concentrate on the specialized structural concrete portion once the site and subgrade were ready for construction.
• The project was performed under federal construction requirements. CSD's subcontract package incorporated certified payroll and prevailing-wage requirements together with Pavex's health, safety and environmental program governing field operations, personal protective equipment, fall protection, equipment operation, environmental controls and safe-work practices.
• The Project Was Completed On 31st December, 2020
