From water and wastewater treatment facilities to large-scale civil and utility projects, our teams bring deep technical expertise, strong self-perform capabilities, and a disciplined, collaborative approach to every scope of work.

CONCRETE

Concrete Construction Expertise

At Prospect Construction, we have built a strong reputation as a premier concrete contractor. Our experience spans a wide range of structures, including underground shafts, water-retaining structures, buildings, bridges, and slabs. These projects have required deep expertise in formwork selection, thermal control planning for mass concrete, high-pressure concrete placements, and climbing form systems. Our team brings the technical knowledge and hands-on skill needed to execute any concrete project with precision and reliability.

Mechanical

Mechanical & Process Systems

Our very first project was a wastewater treatment plant, giving us a strong foundation in mechanical and process systems. Since then, we have continued to deliver complex mechanical work—from biogas and sludge systems to air and water process systems. 


We are experienced in installing and fabricating all types of piping materials, including stainless steel, large-diameter HDPE, and specialty mechanical components. No matter the system, we have the capability, craftsmanship, and field expertise to build it. 

Civil

Drafting

In-House Engineering & Project Planning

At PCI, we plan our projects thoroughly before stepping onsite. Our in-house CAD department develops detailed working drawings for our concrete, mechanical, and structural scopes. This proactive approach helps us identify potential conflicts early, protect the schedule, and streamline field execution.

​

We also leverage modern technology - including 3D printing - to model complex concrete lifts and structural elements. These physical models give our superintendents and crews a deeper understanding of the work ahead, improving accuracy, communication, and planning.

Project Management

Building with Purpose

 At Prospect Construction, our project management style is grounded in purposeful planning, disciplined execution, and true partnership. We lead projects collaboratively, aligning early with Owners, Engineers, Subcontractors, and Suppliers to establish clear goals, transparent communication, and shared accountability. With deep self-perform capabilities and in-house engineering support, our teams proactively plan work, manage risk, and control critical path activities to protect safety, quality, budget, and schedule. We emphasize problem-solving over finger-pointing, integrity over convenience, and stewardship over short-term gain—bringing technical expertise, decisive leadership, and respect for every contributor. The result is a delivery approach that builds trust, strengthens relationships, and consistently delivers complex infrastructure projects that serve communities for generations.
