Who We Are

Kohnen-Starkey, Inc. (KSI) is a Small Business Enterprise (SBE) providing high quality Cost Estimating, Constructability Evaluations, and Value Management Services for the Architectural, Engineering, and Construction Industry.  KSI’s experience in construction cost estimating, project management and design covers a wide range of project types for the Commercial, Industrial, Medical, Aviation, Transportation, and Federal sectors.  Our services support all aspects from procurement and pre-construction services to detailed cost estimates and design and construction schedules of detailed construction documents.  Our procurement and pre-construction services include: Initial Planning of Design-Bid-Build and Design-Build projects, Feasibility Assessments and Studies, Master Planning, Constructability Reviews, Value Engineering Workshops, Concept Scheduling, Analysis of Procurement and Construction Packaging & Methodologies, and Sustainability Cost Studies.


EXPERIENCE:  KSI incorporates experience in all of the construction disciplines including Civil, Structural, Architectural, Mechanical, Fire Protection, Electrical, Technology, Project Management, and Scheduling.  All of the KSI personnel have extensive contractor backgrounds and hands on experience that have proven to be a valuable asset for understanding all of the components that go into a project with limited information available.  This experience is particularly important in the early stages of design, when the amount of detail associated with a given project is limited.  KSI takes pride in establishing accurate estimates with the detail that allows the client to easily identify and understand the specific scope that is included in the project estimate, and by eliminating all of the guess work.  KSI has developed the same “at risk” approach to cost estimating and scheduling that a contractor does, by not only reviewing the documents for scope but also for constructability and value engineering opportunities that may enhance the project.  KSI has never missed a deadline, and takes pride in being prompt with all project deliverables.
