Professional Engineer (Ohio), 43 years experience as follows: 8 years experience as hands-on contractor project engineer on highway and heavy construction projects (Complex metropolitan multi-level interchanges, railroad bridges, structures over major rivers.) The hands-on construction experience was the perfect training for the succeeding 35 years of design/management experience at Kohli & Kaliher, starting with highway and bridge design, reports, bridge inspections—leading to project management of complex highway projects including complex roadway, complex structure design (Level 1, 2 and 3), curved girder, railroad structures (fracture critical), building underpinning, tieback and cantilever retaining wall designs per ODOT requirements. His length of tenure has proven Dan’s commitments to his clients and their projects, and has enabled him to guide simple to complex projects from planning and preliminary development phases through the final design. He does not hesitate to network with other engineers and managers in the field to enhance and utilize the depth of expertise that K&K brings to a project.

Other Interests

Dan is active in professional, civic and church activities. He has taken leadership roles in the Lima Chapter of the Society of Professional Engineers (President, Vice President, and Secretary). He was instrumental in establishing the Northwest Ohio Literacy through Church People for Change and Reconciliation, and served as its Charter President. Dan also has been active in mission projects to South Carolina (10 years to Williamsburg County – second poorest county in the U.S.) and is currently active in mission projects to Haiti (15 yrs) – the poorest country in the western hemisphere.

Personal Motto

I believe that our greatest blessing is to be a blessing to others.

Since being hired to work on the survey crews after his graduation from Purdue University in 1978, Mike has spent over 35 years with Kohli and Kaliher. In 2002, he became a principal with the firm, and is currently the company secretary. He also serves as the Chief Surveyor for the company and is the main contact person for survey proposals. He specializes in the preparation of legal descriptions and drawings for property surveys, and for bridge and highway projects—including the U.S. 30 relocation east of Beaverdam, the U.S. 24 Bypass Improvement at Defiance, the Eastown Road Improvement in Lima, the Ottawa River Bikeway Project in Lima, the Vine Street Railroad Grade Separation Project in Lima, and the Shawnee Road Roundabout Project in Lima. He is also responsible for the preparation of all right-of-way plan sheets that are required for those types of projects.

Through the years, Mike has also had significant experience with topographic and title insurance (ALTA) surveys, engineering design, and site planning—especially for industrial and commercial properties. The Eastgate Shopping Center east of Lima is a good example of an ongoing development project where Mike has been involved with several aspects of surveying and engineering work. He is also responsible for the preparation of subdivision plats, annexation plats, and street dedication or vacation plats.

Other Interests

Mike’s passion for maps and history has served well in his research work on roads and highways—both as a professional surveyor and as an amateur historian. He is regarded as one of the leading authorities on the history of the Lincoln Highway in Ohio, proclaimed in 1913 as the nation’s first transcontinental automobile route. He has prepared a unique compilation of his research, photographs, and original drawings in a self-published book entitled A History and Road Guide of the Lincoln Highway in Ohio.

His similar fascination with railroads has inspired Mike to develop a continuing education program entitled “I’ve Been Learning on the Railroad,” which has been presented on several occasions at conferences of the Professional Land Surveyors of Ohio. The first presentation of this program was at the PLSO Fall Conference in Lima in October 2003, where Mike also served as the program chairman. The entire event was hosted by the Treaty Lands Chapter of PLSO, in which Mike has been active as either president or secretary for many years. He continues to create other continuing education programs not just for his own professional development, but for the professional development of other Ohio surveyors.

Since beginning at Kohli & Kaliher Associates, Inc. in 1990, Mark has advanced from a design engineer to a principal with the firm. He has extensive experience in project management and design of transportation projects from preliminary development through construction. The projects range from small bridge replacements to large bridge rehabilitations with the use of part-width construction. Experience also includes all aspects of street and highway design ranging from small village streets to large 4-lane highways. Mark is also proficient in the preparation of U.S. Army Corps of Engineers Pre-Construction Notifications, having successfully written, coordinated and obtained approved permits from the corps where required on bridge projects.

Design Engineer

As a design engineer, Mark has specialized in managing and developing bridge and highway construction contract plans for ODOT, area counties, and cities. He is proficient in the design and analysis of steel beam/girder superstructures; prestressed reinforced concrete beam superstructures; various types of reinforced concrete abutments and piers including foundations; bridge hydraulics; and all aspects of roadway design. Other duties include the preparation of bid documents and the administration of projects through the construction phase.

Project Manager

As a project manager, Mark has coordinated the plan development for numerous bridge and roadway projects. Most notably he was project manager for DEF-24-7.96 which was a $36.7 million dollar project for ODOT District One. This project improved three miles of U.S. 24 from an existing Super 2 highway into a 4-lane divided highway, which also included the design of two twin river bridges, one twin overpass structure; the complete redesign and replacement of the U.S. 24 / S.R. 15-18 interchange; and the construction of a connector road and other intersecting roads.
