Precede your report proper with a "Title Page," a "Letter of Transmittal," an "Acknowledgments" page that credits all contributors and a "Table of Contents."
Present an overview of your report's subject, goals and methods under the heading "Introduction." For example, you could begin with "(Your company) conducted a review of the existing conditions of XYZ High School Classroom Building. This analysis will provide (the owner) with the necessary information to determine the future direction for the facility."
Provide a "Background" section to relate the evolution of the old school building. Indicate when it was originally constructed and how it is used today. Describe past expansions or renovations and indicate the building's current size and student capacity. Relate the old school building's significance to the master plan of the campus on which it is situated.
Describe your methodology under the heading "Approach." Indicate the multiple disciplines that were involved in the assessment, such as architects, engineers, building envelope consultants and so forth. Describe how your team conducted on-site observations, reviewed original design documents, and met with school users and maintenance staff to understand building performance issues.
Present your report's findings under "Results." Include supporting visuals such as building photographs, plans, aerial images and so forth. Create a "Site Assessment" sub-section to describe, discuss and evaluate the old school building's site conditions, access, parking, drainage and utilities. Similarly, create a "Building Assessment" sub-section to describe, discuss and assess the condition of the existing building's structural, mechanical, electrical and plumbing systems as well as exterior walls and roofing. Provide a room-by-room analysis of the building's windows, interiors and aesthetics, asbestos conditions and compliance with current building codes and the American Disability Act requirements.
Conclude your report with a "Summary" of your main observations and interpretations and then present your "Recommendations," if requested. To further help your readers make a sound decision on the future of the old school building, you could recommend multiple scenarios along with corresponding ballpark costs.
Attach all supporting documentation to which you will have referred in the body of your report under "Attachments." These may include a campus master plan, special engineering reports and so forth.
Distill your entire report into an "Executive Summary" of your main points and results. Insert this summary between your "Table of Contents" and "Introduction."
