Projects

DESCRIPTION

This Design-Build project involved extensive drainage and stormwater storage capacity improvements at the Kyrene Generating Station, part of Salt River Project’s (SRP) Tempe Service Center (TSC). Constructed within an active SRP power generation facility, the project required meticulous planning and strict adherence to safety protocols due to constrained work areas and overhead transmission lines. Site clearances and worker safety were prioritized throughout, as the facility remained fully operational. Additionally, the entire site is located on an ancient Native American village, adding unique archaeological sensitivity. Banicki collaborated with a local archaeologist who was on-site continuously during excavation to monitor for and preserve any discovered artifacts.

DESIGN PHASE SERVICES

During the design phase, Banicki partnered closely with designer SDB to scope, quantify, design, and price all civil and drainage improvements. To meet SRP’s goals within budget constraints, Banicki applied targeted value engineering, optimizing the parking lot pavement section to reduce costs while maintaining durability. Additionally, the team selected cast-in-place (CIP) concrete pipe for the underground stormwater storage, replacing the originally planned HDPE pipe to enhance longevity and structural integrity. Banicki also developed phasing packages aligned with SRP funding schedules, ensuring cost-effective delivery without compromising quality. Detailed phasing and logistics plans were created to allow construction activities to proceed seamlessly alongside SRP’s operations, with no impacts on power generation.
