As a subcontractor to McCord Development, Zachry delivered the Rough Grading Package for the Generation Park East development in Houston, Texas. The project encompassed a comprehensive scope of site preparation and earthwork activities to support future vertical and infrastructure development.
Work included implementing stormwater pollution prevention measures, removing the existing wastewater treatment plant (WWTP) main and associated foundations, excavating on-site swales and constructing a sedimentation basin, importing and placing engineered fill materials, and installing storm sewer infrastructure. Zachry’s scope also included mass grading operations to establish design grades and ensure proper drainage across the site.
Project quantities include:
- 172,928 Cubic Yards Excavation (Site)
- 409,000 Cubic Yards (Channel)
- 413,439 Cubic Yards of Embankment
- 2,240 LF RCP (pipe ranges from 12-inch to 72-inch)
- Related Storm Drainage Elements (Concrete box culvert and junction box)
- 4,439 Cubic Feet of Crushed Limestone Base (6”)
- Removal of Sanitary Sewer Elements
- Removal of Force Main
Fill placement operations were executed in controlled lifts not exceeding eight inches in loose thickness, with each lift compacted to a minimum of 95 percent of the maximum dry density in accordance with project specifications. All materials were verified to be free of organic matter, debris, and other deleterious substances to ensure long term site stability and performance. Through careful coordination, quality control, and adherence to environmental and safety requirements, Zachry delivered a stable, build ready site that supports the overall development schedule and objectives.
