The written
report of the PSCA is typically provided to the Designer to
assist in the preparation of the specification/technical
provision or plan notes. Depending on the results of the
PSCA, complete removal of the existing paint system may be
necessary; however, the existing paint system may be a
candidate for “overcoating.” When performed properly, an
overcoat paint system can save thousands of dollars,
while continuing to protect the steel. Although not widely
known in the bridge market, properly applied “new
construction paint systems” should not need to be completely
removed if properly maintained; whereas, overcoating should
always be a viable option. However, without performing a
PSCA or having effective new construction paint inspection,
overcoating should not be specified.
In
addition, we believe maintenance painting specifications
should include requirements for contractor quality control
or a quality management system (QMS. The QMS should be a
structured program that includes qualified personnel that
perform onsite activities and internal auditing to ensure
compliance with all of the project requirements. The
primary goal of a QMS should be the production of objective
data/proof of project conformance. A good example of a QMS
is outlined SSPC QS-1 Standard Procedure for Evaluating a
Contractor’s Advanced Quality Management System.
