Crowder was the prime contractor for this project at the Marine Corps Air Station in Cherry Point, NC. Crowder self-performed 89% of the work on this project, including the primary and secondary electrical services, 2500KVA transformer, exterior lighting, air conditioning, structural steel, water, sanitary sewer, sewer lift station, fuel tank storage, demolition of existing structures, relocation of existing utilities, site clearing, earthwork, concrete pavement, sanitary sewer pumping station and water distribution. A Final Performance Evaluation completed by the Owner resulted in an “Outstanding” rating. Crowder was awarded the 2009 ABC Excellence in Construction Award for this project.
Crowder was selected by a landfill gas-to-energy developer, Methane Power, to be the design-build contractor for this new system. Crowder installed a gas conditioning and cleaning skid to interface with an existing collected, flare and compression system. In addition, Crowder installed three 1.1 MW GE Jenbacher 320 units with spark ignition engines. This design-build project created a public/private partnership between the private investor, who provided the funding, and the City of Durham, who owned the landfill. This project provided gas treatment that includes moisture removal, particulate filtration and the interface of a SCADA and monitoring system for the entire facility. Crowder was involved in all aspects of detailed design and permitting and self-performed 90 percent of the work. The project was completed ahead of schedule and within budget.
In 2005, Crowder was awarded a contract to expand and upgrade the City of Wilmington’s existing 8 million gallon per day (MGD) Wastewater Treatment Plant to a 16 MGD plant. Maintaining the plant’s operability at all times throughout the construction project was of primary importance to the City. Communication, coordination and planned sequencing were key components to the success of the project. Crowder completed work on sludge dewatering/drying beds, sludge thickening, aeration tanks, blower/generator buildings, trickling filters and pump stations. In addition, Crowder built a new effluent pump station, completed modifications to existing blowers and added chlorination facilities. Crowder’s electrical contract included an entire power scheme for the plant, from the transformers to the substations. Electrical service was provided for the new facility, and new service was established for the existing plant. Crowder self-performed the concrete, equipment setting, piping and all electrical work on this project, which was completed on time and $6 million below budget. The Carolinas Chapter of the Associated General Contractors of America (CAGC) named this project the “Best Utility Project” of 2009 and awarded the 2009 Pinnacle Award to Crowder.
This project was a result of the need to expand effluent filter capacity at a site with significant existing infrastructure and unknown subsurface conditions. Power lines further complicated the already tight site conditions and continuous operations of the wastewater facility were critical to the owner. Conditions and circumstances created a demand for an alternative procurement process to provide best value to the local community, to minimize risk to cost and schedule, and to deliver a project that would allow for analysis of best materials, means and methods for the needed improvements.
The scope of work for the project included:
Open communication between the owner, engineer, and contractor resulted in cost savings, plant efficiencies, and superior performance at the finished facility. Close coordination with regulatory agencies ensured prompt reviews and a clear understanding by all parties of the path forward.
Crowder was awarded this to expand and upgrade a fully-functioning water reclamation facility. This plant, which serves the emergent northeast portion of Clayton County, was near capacity, and the upgrade expanded the facility’s wastewater treatment capability from 6 MGD to 10 MGD. Crowder built or upgraded more than 25 facilities on this project, including a new influent pump station, preliminary treatment facility, primary sedimentation tanks and electrical equipment buildings. The new and improved plant features treatment processes that will improve the quality of wastewater leaving the plant. The project was completed under budget and six months ahead of schedule. Crowder self-performed more than 90% of all work on this project.
The R.M. Clayton Wastewater Treatment Plant is one of the largest wastewater treatment facilities in the Southeast. It has a permitted capacity of 100 MGD and a current average flow of 70 MGD, including both primary and secondary treatment unit processes. Crowder was contracted to perform this design-build, cogeneration project that provided a means to capture the energy potential in the digester gas and convert it to electrical power and thermal energy. The electrical power provided some offset for the current power usage at the facility. Crowder was responsible for the design, installation and start-up of major project elements including one biogas-fueled internal combustion gas engine generator, the combined heat and power process to recover thermal energy used in digester operation, and electrical facilities connecting the engine-generator equipment to the electrical power grid.
Crowder successfully completed the 170-acre project at the Simon Solar Farm Photo Voltaic Plant in Social Circle, GA despite challenges such as the discovery of a vein of rock covering approximately 8 acres which resulted in the relocation and redesign of a portion of the work. The project was completed and online before the end of 2013 and is now operating at its full 30 megawatt capacity.
