Palo Verde Cooling Tower Renovation and Repairs

Palo Verde Nuclear Generating Station, the nation’s largest power producer, was undergoing its 17th refueling outage process in Unit 1 and was in need of services for various work on the unit’s cooling towers to be conducted both safely and efficiently. 


Tons of material removed


Dropped Items


Fill material components removed and replaced


Recordable injuries


One of the primary challenges faced by contractors on the project was to complete work activities within the window applicable to individualized work scope.


Lessons learned from previous cooling tower repair work has allowed for a more streamlined approach to complete tasks within the scope. Application of such improvements has reduced the time needed to complete work in two ways. One example of how lessons learned contributed to time reduction is by identifying more efficient methods of performing activities. The second time saving strategy was made possible through advances in equipment attachments and use. 


The new hire process included much more than the issuing of employee handbooks and completion of paperwork. New employees were introduced to both the core values and expectations that are applied to every job. Job specific training enhanced the workers’ knowledge of duties they would have in the field. This training included classroom instruction, written examinations, and mock-up time.


Work activities during Palo Verde Nuclear Generating Station’s 17th refueling outage in Unit 1 was completed within the 18-day window allotted. This project was, more importantly, performed without any recordable injuries or dropped items.

3R21 Palo Verde Generating Station N1 Polar Crane Replacement Project

Palo Verde Generating Station entered into an agreement with Konecrane to modernize and improve the safety of the plant’s (3) existing 225/35-ton polar cranes. Our team provided qualified supervision, non-working oversight, and manpower to support Konecrane on this project.





Work Window




Recordable Injuries

Several critical challenges were present on this project. The scope of work that had to be completed in only 14-days was one such challenge. Our team managed everything from work orders, holding permits, FME monitoring, machine work to motor alignments. We supported a total of 3 work groups for the duration of the job. Moreover, the work required 24-hr coverage from kickoff to completion.

Manning the job with a total of 4-crews and staggering the shifts proved to be the best method to meet the full coverage requirement of the Polar Crane Replacement Project.

3R21 PVGS Polar Crane Replacement Project was completed on time, within budget, and with zero recordable injuries.

2018 APS Sundance Power Plant - Ammonia Tank & Piping Replacement

Our team provided qualified supervision, safety oversight and manpower to perform the Ammonia Tank and Piping Replacement Project at the APS Sundance Power Plant. The ammonia tank has a crucial role in plant operations as it works to eliminate NOX emissions. The ammonia tank works as a catalyst for emissions in the selective catalyst reduction system (SCR) system. Attention to detail was critical on this project as any complications could have resulted in a delay in bringing the plant back online.


The general scope of the Ammonia Tanks and Piping Replacement was to install two (2) new 15,000-gallon (each) ammonia storage tanks, as well as furnishing and complete installation of all-new piping and associated valves, fittings, etc., to replace the ammonia distribution piping. This work was scheduled within a 40-day window.


One of the lessons learned from this project stemmed from the acid tanks being manufactured by a third-party vendor. In order to mitigate challenges with discrepancies on drawings and the physical tanks, our team took a proactive management approach. By using value-added engineering techniques, our team identified the issues and remedied the issues during the prefabrication. We were able to save our client money through the early detection and correction of these obstacles.


The installation of over 2,000 ft of pipe within the timeline of an outage window was a significant challenge on this project. This scope was a short-duration critical path activity within the outage work window. The pipe installation was completed safely, on time, and within budget. Our team is exceptional at adhering to plant policies and procedures; thus, enabling us to be successful in this critical path work window.

APS Water Resources' Facility Acid Tank Replacements Unit 2 and Unit 3

As part of Water Resources’ Chemical Injection system for providing the cooling water to the site, sulfuric acid is injected into the CW canals at each unit to the control ph levels. The sulfuric acid is stored in large tanks (2 tanks at each CW canal, “A” and “B”). Over time, these large tanks deteriorate or corrode from the inside out and need replacement. This work has approximately 4.5-month windows, excluding scheduled refueling outages that fall within those timeframes. A major portion of this work scope involves replacing two acid tanks for each unit, several hundred feet of stainless-steel pipe, and all associated valves and fittings.


A valuable lesson learned from the first phase of this project was noted in the planning. The lead time for specialty valves was identified early on as being 9-weeks long.

Our team quickly went to work developing a contingency plan to reinstall the old valves in order to allow time for the new equipment to arrive.

Plant engineering approved this method and the work was completed safely and on time.

(SRP) Santan Valley Generating Station Oil Water Separator (OWS) Installation

SRP’s Santan Valley Generating Station was experiencing equipment reliability issues with an oil water separator (OWS). This work consisted of removing an existing underground oil-water separator (OWS), installation of a below grade vault and installation of a new above ground oil-water separator inside the vault and associated piping and instrumentation.

The possibility of the OWS tank leaking upon excavation presented a substantial environmental concern.

Excavating from the sides of the tank first was key in early identification of possible leaks. It was also imperative to switch from hydro excavation to mechanical excavation. By using mechanical excavation, our team was able to more accurately account for any extra moisture in the area around the OWS tank.

The OWS tank was removed safely, and without any environmental complications or concerns.
