Current Projects

Typically Irvinbilt Constructors, Inc. has from four to six projects in various stages of completion underway at any one time. We invite you to view our slate of current projects on this page.


Smithville Missouri Raw Water Pump Station

Project: Raw Water Pump Station
Owner: City of Smithville
Location: Smithville, Missouri
Engineer: HDR, Inc.
Contract Amount: $2,983,795
Scheduled Completion Date: March 15, 2023
Superintendent: Brad Zahner

This project replaces the existing Smithville raw water pump station. The controlling butterfly valve and reducer at the base of the Smithville Reservoir dam are also being replaced. This infrastructure controls the flow of water from Smithville Lake to the pump station and provides a mechanism for Zebra mussel control at the raw water intake facility by using a copper ion system.

In recent years the raw water pump station had flooded, damaging electrical equipment. The pump station was also reaching its rated capacity. This project will locate the new station at a higher elevation above the flood plain. It has room for three pumps, two pumps now and one in the future. The station will have a separate electrical control room and a chemical feed equipment room.

The current raw water pump station is designed to send 2.5 million gallons of Smithville Lake water to the plant in a twenty-four-hour period. Based on the predicted population growth, the city plans to design and construct a 5 million gallon a day plant with completion in 2025. The raw water pimp station project is the first step in this process.

The new butterfly valve at the toe of the dam will have a bypass so future maintenance will be more accessible. Zebra mussels have been identified as a major issue. The mussels attach themselves to water intakes, which can lead to clogs. To prevent them, an ion exchange system will treat the raw water and control the mussels.

Water Treatment Plant (mechanical subcontract)

Project: Water Treatment Plant (mechanical subcontract)
Owner: City of Lexington
Location: Lexington, Missouri
General Contractor: Radmacher Brothers Excavating Company, Inc.
Engineer: Bartlett & West, Inc.
Contract Amount: $1,329,700
Scheduled Completion Date: December 9, 2023
Superintendent: Mike Tripp

This project consists of constructing a new 1.2 million gallon per day water plant, along with a new well field, under a separate contract. This plant will provide quality water for the next generation to Lexington and allow the city to increase water sales to the surrounding area, if needed. The project will also convert the city’s water system from one using surface or river water, to one using ground well water.

The project involves building the new water treatment plant, including two lime sludge lagoons, a recarbonation basin, installation of three steel package gravity filters, chemical feed and storage equipment, two solids contact units, one aerator, chlorine detention piping, process piping, and installation of the following equipment: carbon dioxide storage and feed panel, lime silo and feeder, steel gravity filters, supervisory controls and data acquisition (SCADA) equipment, electrical switchgear, and two generators. The project also includes plant electrical, mechanical, and plumbing along with grading, seeding, and crushed rock and concrete paving around the plant.

Irvinbilt Constructors is performing the mechanical subcontract for the general contractor, Radmacher Brothers Excavating Company, Inc. This portion of the project involves yard and process piping, valves, and fittings.

Owner: Northwest Wholesale Water Commission
Location: St. Joseph, Missouri
Engineers: Bartlett & West, Inc. and CDM Smith
Contract Amount: $3,247,300
Scheduled Completion Date: December 2023
Superintendent: Steve Case

This project will supply water to several area communities. Construction of a pipeline serving Cameron, Maysville, and Stewartsville, had long been a dream of the Great Northwest Wholesale Water Commission. The project consists of a package pump station, a 450,000-gallon ground storage water tank, a centralized 300,000-gallon elevated water storage tank, and a 36-mile pipeline, under three separate contracts. Irvinbilt Constructors was awarded the contract for construction of the pump station and ground storage tank. BRB Contractors, Inc. will install the pipeline, and Caldwell Tanks, Inc. will provide the elevated storage tank.

The pipeline will run parallel with U.S. Highway 36 and Missouri Highway 33. With Missouri American Water Company, we are constructing the ground storage tank and pump station on a site on the east side of St. Joseph. The pipeline will extend to an elevated tank east of Stewartsville. From there, a line will run to Cameron, and another portion will be installed north along Highway 33 to Maysville. All three cities will receive domestic water as a result of the project.

In addition to constructing the concrete ground storage tank and pump station, Irvinbilt is providing the site grading, crushed rock paving, chain-link fencing, interconnecting piping, instrumentation, and electric work at the St. Joseph site.

Site paving will be a combination of concrete and crushed rock.

Southwest Wastewater Treatment Plant and Primary Treatment Rehabilitation

Project: Southwest Wastewater Treatment Plant and Primary Treatment Rehabilitation
Owner: City of Springfield
Location: Springfield, Missouri
Engineer: Burns & McDonnell
Contract Amount: $3,682,640
Scheduled Completion Date: February 15, 2024
Superintendent: Brad Zahner

Springfield’s Southwest Wastewater Treatment Plant, constructed in 1959, sends 35 million gallons of sewage flow to Wilson Creek each day. The city council realizing that the existing equipment is corroded, outdated, and past its useful life, and wanting to make sure they are following state and federal regulations and are taking care of Wilson’s Creek, moved forward with a plan to rehabilitate of part of the plant. This project will provide an additional pump that will increase the plant’s capacity for incoming water from 75 million gallons per day to 100 million gallons per day.

This added capacity will reduce the risk of the plant being non-compliant with state or federal regulations during heavy rain events when storm water flows are high. Also, more than thirty old corroded aluminum gates used to control sewage as it moves through the plant, directing flow to different basins, will be replaced. The new gates will be made of stainless steel and will have automatic actuators that allow the gates to be controlled remotely from the control room.

Additional work involves replacing conduit, wiring, weirs and mixers in sewage basins. The project will also add oxygen sensors that detect how much oxygen is present in the sewage and automatically control the aeration.

Customer Testimonials

We have performed over forty subcontracts for Irvinbilt Constructors and Irvinbilt Company earlier. We first started with Irvinbilt in 1998 when Don Garrison was running the water, wastewater, and pool division of the company. From day one they have been the best general contractor for whom we have worked. When Joe Garrison took over it was a seamless transition and we've experienced all the same positive benefits in working with Irvinbilt since we started work for them twenty-four years ago.
