The Importance of Specification Writing Neil Pittman Sr. Corrosion Engineer Lake Superior Consulting npittman@lsconsulting. com

WHY? �A specification becomes a legal part of the contract. �Defines what is to be done. �Identifies what coating to use. �Removes assumptions and miscommunication. �Promotes Cooperation. �Good paints fail. 4: 10 AM 2

WHO? �Employ a coating engineer. �Hire a consultant. �Send an employee to NACE CIP 1. �Have a corrosion engineer write it. �Plagiarize � Munger, Charles – Corrosion Prevention by Protective Coatings, Houston: NACE International, 1999. � NACE International � SSPC � Coating manufacturers’ literature 4: 10 AM 3

WHEN? �Send specification out with bid package. �Review at pre-bid meeting. �Review at prejob meeting. �Train inspectors and applicators. 4: 10 AM 4
