Total renovation of high school earns praise from client

In 2021, Carl A. Nelson & Company was engaged by the Burlington Community School District to provide construction management services for master planning, pre-construction and construction of a project that resulted in complete renovation of the interior of Burlington High School, which opened in 1969 and had not been updated since with the exception of several small additions.

Through the master planning process, a list of wants and needs totaling more than $100 million was identified — for which a budget of approximately $43 million was available. The School Board opted to focus on the needs, and rather than expanding the footprint significantly (aside from a new fitness center that was needed to replace interior space taken up by mechanical systems) invested in upgraded HVAC and building mechanical systems, and a to-the-studs renovation of the academic wing of the building.

Work started in 2022 with HVAC and mechanical upgrades, followed by the fitness center addition. The rest of the building was renovated in seven phases (plus three summers), with work completed during second shift to limit disruptions to the school day. Savings identified during construction, as well as income from invested bond funds, enabled the district to expand project scope to include a new gym floor, partial gymnasium roof replacement and replacement of the tennis courts. School opened on-time in August 2025.

“That trust factor ... and that relationship is key. ... There are just so many pieces that come with putting together a $43 million high school. ... I've been just overwhelmed by the leadership of Carl A. Nelson.”

Robert Scott, Superintendent, Burlington CSD, Burlington, Iowa

CANCO team guides addition project to successful completion

IKM-Manning Community School District in west-central Iowa engaged Carl A. Nelson & Company to assist with master planning ahead of a 2023 bond referendum. When that vote fell short, the district proceeded with a project using revenue from state sales tax and existing physical plant levy funds to address needs at the middle school/high school in Manning, Iowa.

The construction management project included the addition of a secondary gymnasium, a new commons area and a pair of STEM/makerspace classrooms.

Ground was broken in the spring of 2024, and completed in time for school to start in August 2025.

“They understand the logistics. They understand all the different stakeholders and what everybody wants out of it, and help you to be ... realistic on what can happen with a certain amount of money.”

Dr. Angela Huseman, Superintendent, IKM-Manning CSD, Manning, Iowa

Superintendent gives top marks to CANCO team

As the Sioux Center Community School District prepared to open its brand new, $42 million, 180,000 square-foot high school building, Superintendent Gary McEldowney had only good things to say about Carl A. Nelson & Company and the value the firm brought to the project in its role as construction manager.

The superintendent also offered a complimentary critique of the Carl A. Nelson & Company construction management project team. You can watch that video here.

BONUS: The project architect had some pretty nice things to say about our leadership, too. That video testimonial is here.

“... if it went like this again, I’d be willing to start tomorrow to do this again, because I felt supported along the way. ... Trust was established very quickly, and was carried out through the end of the project.”

Gary McEldowney, Superintendent, Sioux Center CSD, Sioux Center, Iowa

“I would recommend (Carl A. Nelson & Company) to anyone. I would stand behind their work, because I have seen the quality. I know they follow through with their commitments. And they’ve done well in Shenandoah, and they’ve served our community in an outstanding way.”

Dr. Kerri Nelson, Superintendent, Shenandoah CSD, Shenandoah, Iowa
