Estimates

Class “D”: A class “D” estimate is prepared when a project is at the “Conceptual Design” stage. Conceptual design is defined as the beginning of a project when preliminary spatial needs have been identified, and a space program is being developed. At this stage of a project, conceptual drawings of physical space layouts and elevations are being developed by the architect, and the remainder of the design team are developing and evaluating different ideas regarding the types of systems to be used in the project. Project development at this stage is approximately 30% complete.

Class “C”: A class “C” estimate is prepared when a project is at the “Preliminary Design” stage. Preliminary design is when the space program of a project has, for the most part, been developed but additional changes or additions to the program are still being made. Also, preliminary design and the preparation of detailed specifications for the project in all disciplines (architectural, mechanical, electrical and structural) are underway, and the project development at this stage is approximately 70% complete.

Class “B”: A class “B” estimate is prepared when a project is at the “Detailed Design” stage. Detailed design is defined as having a finalized space program, and having the drawings and specifications for all disciplines (architectural, mechanical, electrical and structural) complete to 99%. Although addendums clarifying certain aspects of the project can still be issued at this stage of a project, we proceed to “Call for Tenders”.

Class “A”: A class “A” estimate is attained when the bids for a project have been received, evaluated, verified, and the award of a contract has been made.  Note if the scope of a project is technically complicated (especially CFI grant applications) an Engineering Consultant may have to be retained for technical expertise in design costing.  The cost of these services will be attributed to the project, whether or not the project proceeds to full completion.
