Projects

Performed under our Coconino County JOC, this NEPA / USFS permitted project provided stormwater infrastructure upgrades to Mount Elden Lookout Road in response to increased flow from the Schultz Creek watershed as a result of the 2022 Pipeline Fire. Banicki was brought on at the 60% design phase to partner with Coconino County Public Works and Natural Channel Design to manage utility conflicts, provide value engineering, plan construction activities around three Kinder Morgan high-pressure gas lines, and perform design and constructability reviews that led to construction starting the same day NEPA clearance was received.

Project scope included a 36’ x 8’ x 4’ modified triple barrel CIP box culvert (8’ x 5’ inner barrel); CIP cutoff walls; CIP headwalls; Contech ArmorFlex articulated concrete blocks; riprap reinforced channels; rock sills with 30” rock; cross vane weir with 48” rock; APS and Lumen utility relocations; guardrail; and a pavement section rebuild. A temporary detour road with automated traffic signals was constructed in order for Mount Elden Lookout Road to remain open throughout all construction.

Value Engineering: One of the dynamics of this project involved construction occurring adjacent to three Kinder Morgan high-pressure gas lines, including the installation of articulated concrete blocks (ACBs) directly over Kinder Morgan’s gas lines with minimal clearance. Kinder Morgan’s preferred supplier and subcontractor for the ACBs was very costly, thus Banicki worked directly with Natural Channel Design and Contech to identify a cost effective ACB system that could withstand the design shear stress, flow velocities, and Kinder Morgan clearance requirements. Banicki also self-performed the installation of the ACBs over Kinder Morgan’s gas lines, saving the County $95K for this scope of work during preconstruction.
