OSE Founders

Orazem & Scalora Engineering, P.A. was established in 1989 to provide consulting services in the mechanical, electrical and plumbing engineering disciplines. The firm's design services include HVAC, electrical power, plumbing, telecommunications, security, audiovisual, lighting and control, LEED®/sustainable design, and mission-critical design.

Our portfolio includes commercial office buildings, tenant interiors, multi-family residential, mixed-use projects, K-12 and higher education facilities, R&D facilities, courthouses, municipal buildings, rural utilities, and detention facilities.

OSE has achieved successful projects through strong working relationships with clients and effective project management. We respect the client's time and cost constraints in providing a well-coordinated, efficient project with a high degree of functional efficiency. In order to meet the client's requirements for excellence and high quality, each and every project is directly supervised by an OSE principal from initial inception through completion of construction.

We believe that every building must provide a high quality environment and be maintainable to achieve true sustainability. The environments we design are safe and comfortable for students, office workers, residents and researchers.

We feel that the quality of our services is the best marketing tool we have. The result of our philosophy is that most of our projects are for repeat clients. New clients have typically been referred to OSE by past satisfied clients.


OSE consistently produces complete Construction Documents which include thorough technical specifications and well-coordinated construction drawings. Our office has developed graphical quality standards to ensure that all construction documents are clear and concise. This reduces delays in construction caused by RFIs. OSE utilizies Computer Aided Drafting programs as well as BIM tools to produce our construction documents.


OSE has an excellent record for providing a well coordinated, efficient project design in a timely manner. OSE's size and multi-discipline capabilities permit the focus of expertise and manpower to meet schedule commitments reliably while maintaining our high quality standards.


Orazem & Scalora Engineering has extensive experience in construction cost estimation and project budget development. Construction cost estimates are produced with recorded local cost references. We maintain regular contact with area sub-contractors to remain current with unit and system material and labor costs.

OSE has earned a reputation for accurate cost estimation and designing projects within budget. Cost estimates are routinely updated to include new project elements and kept current with development of greater detail in the project design.


OSE was practicing green design long before the term became trendy. We are committed to producing sustainable and energy efficient designs for all projects, regardless of whether LEED® certification is pursued.

OSE is a member of the US Green Building Council with five engineers as LEED® Accredited Professionals.


OSE currently has a long-term staff of nine employees which includes six professional engineers licensed in the State of Kansas, engineers in training, and CAD drafting technicians. We have found that our size allows us to design smaller projects as well as those of greater than $10,000,000 MEP construction cost. Productive collaboration of team efforts result in successful, well coordinated projects.


The principals of the firm are licensed Professional Engineers and have multi-discipline capabilities. At least one principal directs the production of every project. They maintain client contact, and personally design or supervise the design of all systems and improvements. Experience indicates that clients appreciate the fact that they can contact OSE and get a prompt response directly from a principal of the firm.
