1500 MW Combined Cycle Repowering Project
As part of a major repowering project, CCC installed massive foundations and all underground electrical and piping.

Scope included:

• All underground utilities and process (electrical duct banks, cooling water lines, natural gas lines, fire water lines, etc).

• Concrete foundations for the CT’s, HRSG’s, transformers, intake structure, cooling tower and associated ancillary buildings. Also included placement of anchor bolts and embedded items (24,000 cubic yards of concrete placed in 8 months)

• Above grade concrete for the transformer isolation structure

• Electrical lighting and power installation in ancillary buildings

CCC Group went on to complete two other major projects for FP&L.
 

CCC Group was awarded the OSHA Star award on this project.

Power Generation from Landfill Gas
Texas

CCC Group’s scope included all necessary activities for the construction of a facility producing energy from methane gas.

Disciplines included: 

• Civil
• Mechanical
• Electrical
• Fabrication

Detailed scope:

• Gas tie-ins to the existing flare facility
• Main header to gas processing & blower skid
• Distribution piping to each genset
• All underground piping & utilities
• Foundations to 6 each Cat 3520C reciprocating gas engine generator set which produce 1.6 mega watt of power per unit
• Constructed gas processing facility as well as several modular buildings
• Fabrication & installation of the module enclosure housing the gensets
• All inter-connecting mechanical piping and equipment
• Owner supplied radiators
• Sound attenuation equipment
• Air intake and exhaust ductwork

Electrical scope:

• Underground raceway systems for HV (15000 volts), 480 volt, and control systems
• Control systems are 24vdc and each module is then connected to an EEM (Electrical Export Module) which controls each generator and ensures safety trips for each unit
• Module work included cable tray and raceway system for the control of the generator
• Safety devices such as methane gas detectors, smoke detectors, and UV detectors

Fabrication Project for the Power Industry
Austin, TX

CCC’s in-house fabrication shop (IMC) fabricated five beams measuring 18" wide x 5' tall x 127' long with their associated cross members.  It only took 4 months from fabrication to field delivery.

These were long span beams designed to clear two railroad tracks and vehicular lanes. The bridge itself was designed to withstand water-truck access and vehicular traffic onsite.

The Challenge
The beams were so long and the site was so constricted that the trucks would not have had enough turning radius to get onto the site. We hired a very specialized trucking company that had custom trailers with hydraulically controlled rear axles that swiveled on the back portion of the trailer; thus allowing access to the job-site without incident.
