Not all construction companies are the same. Corna Kokosing’s brand of Integrity, Quality and Commitment was developed after we surveyed our clients and asked them, “What makes us different from our competitors?” These three qualities are not mere words, rather, they are the core values and behaviors that are delivered to each client and every project that we build. So what do our team members do differently?

We place our clients first.

Our unwavering commitment to our clients is a leading reason why clients say they hire us repeatedly.

We embody quality.

It is embedded in our training programs; it is emphasized in our team members’ performance reviews.

We take it personally.

Because every project and every reference matters to us.

We manage and build.

Corna Kokosing is the largest self-performing contractor in Central Ohio with offices in Indianapolis as well. We manage projects better because we have a refined understanding of productivity and how to schedule labor, materials, and equipment.

We make safety a lifestyle, not just a rule.

We have a Safety 24/7 program that reinforces a “safe way of life” which helped lead to our AGC of America Construction Safety Excellence Award.

Construction Management

Corna Kokosing (CK) has a long history of completing projects under Construction Management Agency (CMa) and Construction Manager at Risk (CMR) delivery methods. CK serves as the owner’s advocate in providing cost estimates, master schedules, phasing and logistic plans, constructability reviews, purchasing strategies and value analyses on the implications of alternate designs, systems and materials. CK will plan, schedule and document projects in order to minimize changes and avoid claims. We ensure that our schedules are thorough, attainable, have “buy-in” from the entire team and have flexibility to accommodate changes.

For owners who have never used a Construction Management delivery method, it is important to note that we maintain an open-book policy so that all costs are transparent.

General Contracting

We are not risk adverse—CK began as a lump-sum general contractor and continues to work under this delivery method to this day. We are comfortable in this role because of our proven record of completing even the most challenging projects on time and on budget—with all of the risk assigned to us.

In this traditional delivery system, the owner engages a designer to prepare the design of the complete facility, including construction drawings, specifications and contract packages. Although usually not optimal for most complex, ill-defined, or schedule-sensitive projects, this contracting system is common for straightforward projects with well-established and clearly defined roles for the parties involved.

Design Build

Design and construction personnel, working and communicating as a team, evaluate alternative designs, materials and methods efficiently and accurately. Value analysis and constructibility are utilized continuously and more effectively when the designers, contractors and vendors work as one during the entire design and construction process.

Because design and construction overlap under this method, and because bidding periods and redesign are eliminated, total design and construction time can be significantly reduced and an early cost guarantee can be established. Design Build is ideal for simple building construction and the application of a “fast track” schedule.

Self Perform Trades

Our trade competencies, combined with our management skills, provide us with a comprehensive and refined understanding of costs, scheduling of material, labor and equipment, and productivity—much more than construction firms who are only construction agents or brokers.

Additionally, as a self-performing contractor, we have the capacity to intervene and supplement forces in the field if a subcontractor is deemed non-performing. We can rely on our own forces, rather than have to wait for another subcontractor’s availability. The result is a quicker response, greater flexibility, and increased productivity.

Our self-perform trades include Carpentry, Casework, Concrete, Drywall/Acoustical Ceilings, Rigging & Millwright, Selective Demolition, and Steel Erection.

BIM & 3D Modeling

CK uses the latest 3D modeling and Building Information Modeling (BIM) technology. Our in-house Central Engineering Services department provides advanced 3D modeling and BIM/VDC workflows that utilize highly detailed layouts for cost estimating, clash detection and design analysis of MEP, structural and architectural systems and components. We have the ability to provide high-quality 3D renderings, virtual walkthroughs and 4D construction sequencing and scheduling simulations. The use of this technology has resulted in time and cost savings to our owners, subcontractors and us.

My fondest memories of being in the industry:

I have been blessed to visit some pretty awe-inspiring and amazing construction projects all over the world. To me, there is nothing better than seeing men and women bring an idea to life and to actually be a part of that. I have walked on the bottom of the Maumee River in a cofferdam 45 feet below water level while boats floated past on top. I visited my largest project ever in the Jiangsu province of East China, with over 4,000 workers on the project site! I have walked inside of the bridge segments of the Veterans Glass City Skyway bridge and was in top of the center pilon at 400 feet above the water. I have been involved on many coaster projects at Cedar Point and was also involved heavily at the Toledo Mud Hens stadium project.

How I give back to the community and industry:

I believe that giving back to others is an important part of what we are supposed to do during our short time on earth. I was a volunteer firefighter/Lieutenant of 35 yeas and loved every minute of it! Seeing how you can make a difference in someone’s day has been so rewarding to me and I would not change it for anything. I also am an advocate for the construction industry and enjoy speaking to others about the opportunities in construction and promoting the industry, particularly to high schoolers.

What is the proudest achievement of my career:

I was recognized as the Safety Professional of the Year, for efforts to promote safety and reduce risk. Being recognized for doing something that I love, was quite a shock as I was nominated by a past employer. Just knowing that I am making a difference is by far one of the proudest aspects of my career.

What I hope my legacy in the construction industry will be:

I hope that people look at me and my career and say “he made a difference and will be missed”. I have a tremendous passion for safety, which sometimes can be viewed as confrontational, but I can assure you that I am focused on the well-being of people.

After completing my first year of college, it was evident that I was more interested in the construction of buildings instead of design. I changed my major to civil engineering and headed down the path of construction management.

Why I like being in construction:

I enjoy being able to drive around the city with my family and point out all of the projects that I played a part in building or knowing that the company I work for built.

I would like to be remembered for being a good leader, mentor, coach, and problem solver. I truly enjoy helping others in our industry learn and develop their own strengths. I want to be someone that people can say they learned a lot from working with me.

History: A Legacy of Growth

1956 1976 1986 1995 2001 2008 2012 2016 2017 2019
1956 1976 1986 1995 2001 2008 2012 2016 2017 2019


Childhood friends Al Corna, a stone mason, and Joe DiCesare, a carpenter, formed Corna & DiCesare Builders. Their first office was located on 5th Ave. Corna & DiCesare started by building houses and completed its first commercial construction project in 1961.


The company became a general contracting firm that specialized in concrete, masonry and carpentry work. It was involved with building many of the high rises and parks in downtown Columbus during the construction boom of the late 1970’s and early 80’s, including Battelle Riverfront Park, OhioHealth Grant Hospital, The Ohio Theatre Esplanade, AEP Headquarters, Nationwide Insurance, among others.


Corna & DiCesare Construction Company continued to flourish with a strong foundation of repeat, private-sector commercial clients, including The Catholic Diocese of Columbus, Medco, Mount Carmel Heath, The Schroer Group, Schottenstein Stores, Casto Development, and many others. Revenues grew from $4.5 million in 1986 to $75 million in 1995.


Corna & DiCesare Construction Company was purchased by the Burgett family and changed its name to Corna Kokosing Construction Company, of which Mark Corna became President.


The new office headquarters was built at I-270 and Westerville Road, which also included a separate Works Department, Mill Shop, and Training Facility. The construction of the buildings utilized the company’s own skilled craftsman, reflecting their quality standards and culture.


Corna Kokosing always built relationships first, which naturally resulted in being awarded some of the most iconic projects in Central Ohio. Such icons were built for Easton Town Center, Columbus Commons, Columbus College of Art & Design, Columbus Crew Stage, Columbus Regional Airport Authority, DuPont, Hilton, JP Morgan Chase, Nationwide Children’s Hospital, and The Ohio State University.


Despite one of the most challenging three-year spans in the history of the construction industry, Corna Kokosing hits all-time revenue high and is ranked No. 1 (based on 2011 construction contract values in central Ohio), according to Columbus Business First.  Significant projects for repeat clients such as the Columbus Museum of Art, Columbus Downtown Development Corporation, Steiner & Associates, Ohio University, and Honda were completed.


As a result of Corna Kokosing’s own team member votes, the company was awarded “Top Workplace” for the first of four consecutive years. Winners of this award were measured on company leadership, communications, career opportunities, work environment, managerial relationships, pay, and benefits.


Corna Kokosing expands its regional footprint by opening a new full-service office in Indianapolis, IN.


Third generation owner, Lori Gillett, became Corna Kokosing’s CEO and Jim Negron became President.
