An Evaluation of MoDOT's Current Coatings Programs Final ... - TSP2

contract on all overcoating and recoating projects in the contract maintenance
program. For the high pressure water cleaning to be effective, it is
recommended that the current maximum pressure of 1,500 psi be increased to a
maximum pressure of 10,000 psi.
Training for MoDOT Personnel – Additionally, in the overcoating process, the
engineer is designated as the person who will ensure that the contractor is
removing enough material (loose paint, corrosion, etc.) to enable the new coating
to perform properly. Training for MoDOT personnel by one of the recommended
training programs (described in Appendix D) will provide MoDOT engineers with
the knowledge to ensure quality coating application.
Pre-Bid and Annual Standards Meetings – The team recommends that it
would be beneficial to MoDOT and the contractor to hold pre-bid meetings on all
coating projects in order to review the requirements and expectations for the
project, and to discuss all facets of the project and any unusual concerns the
contractor may have about the project.
While the team was reviewing the current processes in the contract maintenance
coating program, one common theme that arose was that the contractors may
not be aware of the expectations that MoDOT has for the painting program. As a
result, the team explored the possibility of creating an annual standards meeting.
This meeting would be held early in the calendar year (January, February, or
March) prior to the start-up of coatings operations to review the expectations for
field coating applications. At the meeting, field samples (or mock-ups) of
properly prepared surfaces and applied coatings would be preserved and made
available to both contractor and MoDOT inspectors for their mutual review. As a
result, there would be uniform enforcement of the coating inspection process by
MoDOT. All contractors statewide would know what is expected of them by
MoDOT on any project on which they are working.
It is also recommended that there be mandatory Pre-Bid meetings which require
attendance by all contractors and field coating contractors performing work on
the project. If the contractor does not sign-in in person, their firm will be barred
from bidding (either as a prime or subcontractor) on the contract. It is believed
that by requiring their attendance at both an annual standards meeting and prebid
meetings, MoDOT is ensuring that the contractors are familiar with and
committed to working with MoDOT to provide the best product possible to the
people of the State of Missouri.
On-Site Reference Samples – A concept that was developed by the team while
reviewing the current coating processes was to have the contractor prepare onsite
reference samples. The Task Force recommends adding to the
specifications the requirement that the coating contractor produce and preserve a
surface preparation and coating application sample area on a section of the steel
on the bridge at the jobsite. Based on the application, MoDOT and the contractor
