Primoris Water & Mechanical worked on the Charlotte Douglas International Airport project installing a turnkey utility corridor including chilled and hot water piping, telecommunications duct bank, and all related site work. The team completed the final auger bores under road crossings. Once the critical phases on Rental Car Rd and the airport’s loading dock were substantially complete, the final focus was piping tie-ins; testing and flushing; and startup and restoration.

Installation of approximately 7060 linear feet of piping in multiple systems including chilled water, hot water, steam, condensate, domestic water, and softened cold water. A variety of pipe materials were used including pre-insulated standard weigh pipe, pre-insulated extra heavy pipe, ductile iron, and PVC.

This three-year Design-Build Services agreement provides a mechanism for Palm Beach County to fast-track design and construction for water, wastewater and reclaimed water projects at any of the various county-owned treatment facilities. This contract includes the design and construction of the following systems: chemical feed systems for lime and fluoride; sulfuric acid dilution system; reverse osmosis cleaning and permeate flush systems; finished water storage tank aeration & mixing improvements; temporary bypassing and valve replacements; automation and process improvements; 700hp multistage centrifugal blower for aeration; replacement of existing sluice gates and slide gates; structural and process modifications to headworks; and deep injection monitoring well.

Primoris Water & Mechanical began installing chilled water, steam, and condensate distribution systems for a campus expansion at Southern Methodist University in Dallas, Texas. The piping was installed via a combination of auger boring and open-cut excavation. 

This project consisted of installing approximately 10,500 linear feet of hydronic piping. Pipe systems included DR11 HDPE chilled water lines varying in sizes between 3-inches to 24-inches and scheduled 80 carbon steel double jackets high-temperature hot water lines varying in sizes between 2-inches and 8-inches. Trench depth varied from 4 feet 6-inches to 7 feet.

Primoris Water & Mechanical worked on a Design/Build expansion of the WWRF to a permitted capacity of 10.5 MGD on an AADF. The scope of work included a new aeration basin, modifications to the existing 4 aeration basins, modifications to the existing blower building, a new clarifier, modifications to the existing sludge pumping station, a new injection well pump, and replacement of the existing plant PLC network.

Q3C assisted in relighting Xcel customers that have were affected by the wildfires that occurred near the town of Boulder, CO. Several thousand households around Boulder were without natural gas, and 7,500 households had no power, according to Xcel Energy, the local provider. The company said that electricity would be restored later, but that natural gas would take several days to restore all affected households.

Q3C was awarded this project to fabricate an enclosed interconnect skid including interior piping, valves, instruments, mechanical and electrical equipment, connecting tubing and wiring, and required enclosure lighting, power, and HVAC per the IFC drawings and specification package. The enclosure will be fabricated from a 45 feet long x 8f feet wide x 9.5 feet tall ISO shipping container.
The interconnect skid’s purpose is to receive, meter, and regulate treated landfill gas and send it to pipeline. The enclosed skid shall be installed on private Xcel Energy property adjacent to the existing Rich Valley Valve Station in Inver Grove Heights, MN. Scope of Work: The Contractor shall purchase and modify a 45-foot long, 9-foot tall shipping container with double doors on one end. The Contractor shall procure all pipe, pipe fittings and flanges, tubing, tube fittings, manual valves, support steel, doors, fireproof insulation, and HVAC equipment as included in the IFC drawing package.

R.B. Hinkle installed 5,500’ of duct bank with a case bore under a creek and 19 manholes for a new substation.

R.B. Hinkle completed a 10 mile trench in hard, dense shale soil.
