Project Overview

This design/build project consisted of site work for a new production plant in Middetown, DE. Scope included:

  • Stripping and stockpiling topsoil across the 15 acre site
  • Performing cuts and fills to grade
  • Stripping overburden and importing select fill for structural areas as needed
  • 104k CY of total earthwork
  • Performing well-pointing and installation of underground utilities including:
    • 550’ of sanitary sewer at up to 10’ depths
    • 3300’ of stormwater piping
    • 1000’ of waterline and a large underground meter pit
  • Installing 5,000’ of curb and 12,000 SF of sidewalk
  • 3,000 tons of asphalt pavement

Key Challenges

Corrado worked with Civil Engineering Associates and Wohslen Construction during the early stages of this design/build project to help reduce costs through design tweaks. Some key changes that helped reduce cost were:

  • Adjusting building pad elevation to optimize cuts/fills
  • Incorporating berms into the site design for excess topsoil, thereby reducing export costs

In addition to design tweaks, another opportunity to reduce costs came from working the onsite soils to help reduce the impact of some existing unsuitable soils. This reduced the amount of select material needed and decreased project costs.
