About ASPE


History of ASPE


The American Society of Professional Estimators was founded in 1956 by a group of independent estimators who wanted to exchange job-related information and increase their knowledge and professionalism. The society has grown since that time and currently has thousands of members across the United States. 



The American Society of Professional Estimators serves construction estimators by providing education, fellowship, and opportunity for professional development.

Since the Society’s inception, education has been one of the most important benefits of membership. Each ASPE Chapter sponsors classes directed towards increasing the knowledge of construction estimators. Classes are primarily taught at the university level, although several programs are aimed at high school and technical school students. One of the goals of the Society is to coordinate educational programs on a nationwide basis, establish estimating standards, act as a conduit for collecting and distributing relevant information, and to improve the overall abilities of the Estimator. 


The Society publishes a national monthly magazine Estimating Today, which contains technical papers written by members of the Society. These technical papers address a variety of issue directly related to the field of estimating. Recent issues have contained papers on “How to Estimate the Cost of Reinforced Concrete Beams and Slab Structures” and “Estimating the Cost of Industrial Equipment Foundations.”  .


Estimating Standards


One of the primary goals of ASPE has been to define and publish estimating standards that, when properly employed, will produce reliable estimates in a uniformly recognizable format.  In pursuit of this goal, the Society has written and published the Standard of Estimating Practices. The ASPE© Standard Estimating Practice manual is written by ASPE members and is the “how to” guide to estimating. It provides information on all sixteen CSI divisions. The manual provides basic guidance in estimate preparation and includes industry standards that are the basis for the certification of experienced estimators (CPE’s).




The estimator is one of the primary persons responsible for the evaluation of manpower, materials and equipment required for one of the largest single industries in the world:  the Construction Industry. Government agencies, owners, designers and contractors are seeking the most qualified individuals to generate successful estimates for their construction projects. ASPE has developed and refined a system for evaluating the capabilities of construction estimators. A program for testing and certification has been initiated that includes mandatory attendance at an educational workshop, writing an accurate, acceptable technical paper, successful completion of a written examination and participation in the continuing certification program.




As professionals, we are constantly seeking way to improve our knowledge of estimating and the construction industry. By joining ASPE, you can attend chapter, regional, and national meetings that give estimators the opportunity to share information, exchange ideas and learn about innovative techniques. Chapter meetings provide a professional-level forum to meet other estimators and discuss common problems and successful solutions.




ASPE members believe that the adherence to ethical business practices will result in greater professional success and have developed the following ASPE Code of Ethics:


Basic Canons


Canon #1        Professional estimators shall perform services in areas of their discipline and competence.

Canon #2        Professional estimators shall continue to expand their professional capabilities through continuing education programs to better enable them to serve clients, employers and the industry.

Canon #3        Professional estimators shall conduct themselves in a manner, which will promote cooperation and good relations among members of our profession and those directly related to our profession.

Canon #4        Professional estimators shall safeguard and keep in confidence all knowledge of the business affairs and technical procedures of an employer or client.

Canon #5        Professional estimators shall conduct themselves with integrity as all times and not knowingly or willingly enter into agreements that violate the laws of the United States of America or of the states in which they practice. They shall establish guidelines for setting forth prices and receiving quotations that are fair and equitable to all parties.

Canon #6        Professional estimators shall utilize their education, years of experience and acquired skills in the preparation of each estimate or assignment with full commitment to make each estimate or assignment as detailed and accurate as their talents and abilities allow.

Canon #7        Professional estimators shall not engage in the practice of "bid peddling" as defined by this code. This is a breach of moral and ethical standards, and a member of this society shall not enter into this practice.

Canon #8        Professional estimators and those in training to be estimators shall not enter into any agreement that may be considered acts of collusion or conspiracy (bid rigging) with the implied or express purpose of defrauding clients. Acts of this type are in direct violation of the Code of Ethics of the American Society of Professional Estimators.

Canon #9        Professional estimators and those in training to be estimators shall not participate in acts, such as the giving or receiving of gifts, that are intended to be or may be construed as being unlawful acts of bribery




Chapter, regional, and national meetings give estimators the opportunity to share information, exchange ideas and learn about innovative techniques. Monthly chapter meetings feature guest speakers on topics of interest to those of each chapter. Serving as chapter officers or on chapter committees provides additional opportunities to learn and serve the profession. Chapter meetings also provide a forum to meet and discuss common problems with competitors and business associates.
