DATE:10-27-26
DEPT:ELEC
SUBJECT:ENGINEERING SERVICES FOR ARC FLASH STUDY FOR THE POWER
PLANT
COUNCIL ACTION FORM
BACKGROUND:
The Power Plant contains a substantial amount of electrical switchgear and other equipment.
As this equipment is added, modified, or adjusted over time, it becomes necessary to evaluate
the potential risks of arc flash and revise the safety precautions that must be taken when
performing certain work. The Power Plant last underwent an arc flash study in 2021. A new
study is necessary to perform short-circuit analysis, protective device coordination, and arc
flash hazard analysis to identify potential electrical hazards, establish appropriate safety
labeling, and improve personnel safety when operating and maintaining electrical equipment.
On July 1, 2026, a Request for Proposals was issued in AmesBids by Purchasing. On July 24,
2026, 18 proposals were received as shown below.

An evaluation team comprised of City staff reviewed the proposals. The proposals were
evaluated on experience and qualifications of the Firm's project team, the Firm's ability and
quality of services that best meets the needs of the City, suitability and clarity of the Firm's
response, and cost.
Two proposals were non-responsive as their proposals did not meet the City's requirements.
After scores from the evaluation team were totaled, the proposal from HDR Engineering
Inc., of Ames, IA, was the highest ranked proposal. Staff is confident in the Firm's proposal
due to HDR's experience, project team experience and qualifications, and the approach
detailed in the proposal.
Given the price spread between the top ranked firms, the evaluation team determined the
increase cost from HDR was supported for the following reasons:
HDR provided the strongest overall qualifications and relevant power-generation
experience, including complex generating facilities, protective device coordination, relay
settings, and arc-flash studies involving multiple operating configurations.
HDR’s proposed scope was more comprehensive and clearly defined, including field
verification, updated system modeling, short-circuit and coordination studies, arc-flash
calculations, mitigation recommendations, labeling, QA/QC, and editable study files for
future City use.
The lower bids presented greater scope and execution risk. Based on staff's review,
some lower-cost proposals had less clarity regarding field verification, modeling effort,
deliverables, revisions, and other assumptions, creating a higher potential for incomplete
work or additional costs later.
Funding for this project will come from the Power Plant O&M account where there is $150,000
budgeted for these services.
2
ALTERNATIVES:
1. Award a contract to HDR Engineering Inc., of Ames, IA, for Engineering Services to
perform an Arc Flash Study at the Power Plant, in an amount not-to-exceed $75,655
2. Award a contract to another firm.
3. Do not approve the request.
CITY MANAGER'S RECOMMENDED ACTION:
The arc flash study will help ensure a safe working environment for Power Plant
personnel by identifying any electrical hazards, evaluating protective device
coordination, and determining appropriate safety measures. Updating the study will
also account for changes in system operations and equipment since 2021 and support
compliance with applicable electrical safety standards. Therefore, it is the
recommendation of the City Manager that the City Council adopt Alternative No. 1, as
described above.
