INTRODUCTION
P
URPOSE

These CAD Standards are a guideline for producing and maintaining CAD drawings for all units of
the University of Chicago and the University of Chicago Hospitals. In this document the term
Institution will be used to refer to both entities and will always include all units of both
organizations.
The purpose of this document is to establish a common standard for AutoCAD data content and
format and to standardize the processes for creating and maintaining that data for all departments
and divisions within the Institution. All personnel and outside vendors working on CAD drawings
for the Institution are required to adhere to these standards.
When submitting CAD drawings to the Institution, vendors are required to follow the instructions
for submittal included in this document and the University of Chicago Close Out Documents
Guide (Appendix C herein). These documents provide a basis by which the Institution may
accept or reject CAD drawing deliverables from consultants and contractors and should be
referenced in all Institution contracts for which plan drawings are required.
C
ONTEXT

This standards document exists within the context of a long term plan to fully automate the
processes of facility management at the Institution. That plan includes the use of AutoCAD
drawings in facilities management, construction, renovation and related tasks. The
implementation of the standards and processes contained in this manual should enable all
involved to understand the specific requirements and help them to deliver high quality CAD
drawings in a cost effective manner.
This document will be revised from time to time as the needs of the Institution evolve and the
technology changes. All users and vendors are required to verify that this document is the latest
version of the CAD Standards. Suggestions and requests for changes and enhancements to the
standards are welcome and should be presented to CAD management in the facilities services
departments of the Institution.
Each department and division may also have its own set of additions to these standards, such as
specific plotting requirements and special discipline block definitions. Please check with
department level CAD management for existence of additional CAD requirements and
documentation.
