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 associates 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 associates’ 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. 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 has a long history of completing projects under Construction Management Agency (CMa) and Construction Manager at Risk (CMR) delivery methods. Corna serves as the owner’s advocate in providing cost estimates, master schedules, phasing and logistic plans, constructibility reviews, purchasing strategies and value analyses on the implications of alternate designs, systems and materials. Corna 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—Corna Kokosing 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

Corna Kokosing has been using 3D modeling and Building Information Modeling (BIM) technology for more than five years. 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.

History: A Legacy of Growth

1956 1976 1986 1995 1998 2012 2016
1956 1976 1986 1995 1998 2012 2016

1956

Childhood friends Al Corna, a stone mason, and Joe DiCesare, a carpenter, formed Corna & DiCesare Builders and started building houses. Their first office was located on 5th Avenue. Al and Joe shared a desk made of a wooden door on two saw horses.

1976

Al Corna’s son Mark, who was a union trained carpenter, started The M.S. Corna Company, a general contracting firm that specialized in concrete, masonry and carpentry work. The company 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, Grant Hospital, The Ohio Theatre Esplanade, AEP Headquarters and Nationwide Two, among others.

1986

Corna & DiCesare Builders and The M.S. Corna Company merged to form Corna & DiCesare Construction Company. The company flourished with a strong foundation of repeat, private-sector commercial clients, including The Catholic Diocese of Columbus, Medco, The Schroer Group, Schottenstein Stores, Casto Development and many others. Revenues grew from $4.5 million in 1986 to $75 million in 1995.

1995

Corna & DiCesare Construction Company became part of The Kokosing Group and changed its name to Corna Kokosing Construction Company. The company gained financial strength (aggregate bonding capacity in excess of $1 billion), as well as professional depth and major equipment resources (3,500 associates; Top 200 construction equipment owners in the U.S.).

1998

Land was purchased at I-270 and Westerville Road to form the Westerville Industrial Park. The office/headquarters was built there — the construction reflects the company’s skilled craftsmen, quality standards, and culture.

2012

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.

2016

Corna Kokosing is chosen as a Top Workplace. Winners were measured on: company leadership, communications, career opportunities, working environment, managerial relationships, pay, and benefits.
