Cefe F. Valenzuela Landfill

DSC00243

Longhorn Excavators, Inc. was contracted for the construction of Cefe F. Venezuela Landfill Site Development for the City of Corpus Christi, Texas. Work was started as the city’s other landfill was running out of space.

Scope of Work

The scope of work included:

  • Construction of five buildings totalling 14,000 square feet
  • Site electrical and utilities
  • Roadways 2.8 miles long by 24 feet wide and parking lots 18,000 square feet
  • Six miles of drainage channels
  • Landfill cell construction
  • Concrete outfall structure
  • Gas pipeline lowering
  • Box culverts and erosions mats
  • Wi-Fi tower and communications

Buildings

State-of-the-art scale house billing was sent to city hall with wireless system. Administrative building, crew building, maintenance shop and gate house were built for a long-term life of use. Buildings were constructed with red iron structure with red stone veneer.

Earthwork

Due to the fast schedule, many earthwork activities had to be performed at the same time.

  • On-site borrow pit was operated to provide select fill, which Longhorn Excavators constructed.
  • Over six miles of major drainage channels were excavated, 2 million cubic yards, to provide drainage using three excavators, 15 40-ton trucks, and four dozers.
  • Two feet cut of over-excavation beneath building, roadways and parking lots. Very little challenges if any.
  • Top soil placement on channels and landscaped the areas with bermuda grass and 30 trees as specified.
  • Landfill cell excavation of 16 acres, 240,000 cubic yards, stockpiled for future use as cover dirt by city.

All these activites were performed simultaneously.

Schedule

This new landfill facility was built “from-scratch” on 3,500 acres of farm land in approximately one year. It was opened before the City’s other landfill was out of space. The site is designed to be usable for the next 100 years.

Challenges and resolutions

The main challenge of this project was meeting the scheduled completion date. By scheduling activities accordingly, we were able to meet the completion without delay.

Subcontractors

We subcontracted Falcon Environmental Lining Systems, Inc. to install over more than 1 million square feet of HSPE 60 million smooth and 36,728 square feet of textured liner. 674,769 double-sided geocomposite 200 mil was also installed at .04 percent of the contract price. BarCom Commercial, Inc. was subcontracted for the construction of site utilities, electrical, plumbing and interior work on buildings (a total of 29 percent of the contract).

Project Details

We transformed a portion of Chapman Ranch in south Texas into a cost-efficient, eco-friendly working landfill – constructing the intake facility, as well as roads, buildings and even computer systems on behalf of the City of Corpus Christi, Texas.
