Test Sections. Prior to surface preparation, the Contractor shall prepare a test section(s) on
each structure to be painted in a location(s) which the Engineer considers to be representative
of the existing surface condition and steel type for the structure as a whole. More than one test
section may be needed to represent the various design configurations of the structure. The
purpose of the test section(s) is to demonstrate the use of the tools and degree of cleaning
required (cleanliness and profile) for each method of surface preparation that will be used on the
project. Each test section shall be approximately 10 sq. ft. (0.93 sq m). The test section(s) shall
be prepared using the same equipment, materials and procedures as the production operations.
The Contractor shall prepare the test section(s) to the specified level of cleaning according to
the appropriate SSPC visual standards, modified as necessary to comply with the requirements
of this specification. The written requirements of the specification prevail in the event of a
conflict with the SSPC visual standards. Only after the test section(s) have been approved shall
the Contractor proceed with surface preparation operations. Additional compensation will not
be allowed the Contractor for preparation of the test section(s).
For the production cleaning operations, the specifications and written definitions, the test
section(s), and the SSPC visual standards shall be used in that order for determining
compliance with the contractual requirements.
Protective Coverings and Damage. All portions of the structure that could be damaged by the
surface preparation and painting operations (e.g., utilities), including any sound paint that is
allowed to remain according to the contract documents, shall be protected by covering or
shielding. Tarpaulins drop cloths, or other approved materials shall be employed. The
Contractor shall comply with the provisions of the Illinois Environmental Protection Act. Paint
drips, spills, and overspray are not permitted to escape into the air or onto any other surfaces or
surrounding property not intended to be painted. Containment shall be used to control paint
drips, spills, and overspray, and shall be dropped and all equipment secured when sustained
7

wind speeds of 40 mph (64 kph) or greater occur, unless the containment design necessitates
action at lower wind speeds. The contractor shall evaluate project-specific conditions to
determine the specific type and extent of containment needed to control the paint emissions and
shall submit a plan for containing or controlling paint debris (droplets, spills, overspray, etc.) to
the Engineer for acceptance prior to starting the work. Acceptance by the Engineer shall not
relieve the Contractor of their ultimate responsibility for controlling paint debris from escaping
the work zone.
When the protective coverings need to be attached to the structure, they shall be attached by
bolting, clamping, or similar means. Welding or drilling into the structure is prohibited unless
approved by the Engineer in writing. When removing coatings containing lead the containment
and disposal of the residues shall be as specified in the Special Provision for Containment and
Disposal of Lead Paint Cleaning Residues contained elsewhere in this Contract. When
removing coatings not containing lead the containment and disposal of the residues shall be as
specified in the Special Provision for Containment and Disposal of Non-Lead Paint Cleaning
Residues contained elsewhere in this Contract.
The Contractor shall be responsible for any damage caused to persons, vehicles, or property,
except as indemnified by the Response Action Contractor Indemnification Act. Whenever the
intended purposes of the controls or protective devices used by the Contractor are not being
accomplished, work shall be immediately suspended until corrections are made. Damage to
vehicles or property shall be repaired by the Contractor at the Contractor's expense. Painted
surfaces damaged by any Contractor's operation shall be repaired, removed and/or repainted,
as directed by the Engineer, at the Contractor's expense.
Weather Conditions. Surfaces to be painted after cleaning shall remain free of moisture and
other contaminants. The Contractor shall control his/her operations to ensure that dust, dirt, or
moisture do not come in contact with surfaces cleaned or painted that day.
a) The surface temperature shall be at least 5F (3C) above the dew point during final
surface preparation operations. The manufacturers' published literature shall be followed
for specific temperature, dew point, and humidity restrictions during the application of each
coat.
b) If the Contractor proposes to control the weather conditions inside containment, proposed
methods and equipment for heating and/or dehumidification shall be included in the work
plans for the Engineer's consideration. Only indirect fired heating equipment shall be used
to prevent the introduction of moisture and carbon monoxide into the containment. The
heating unit(s) shall be ventilated to the outside of the containment. Any
heating/dehumidification proposals accepted by the Engineer shall be implemented at no
additional cost to the department.
c) Cleaning and painting shall be done between April 15 and October 31 unless authorized
otherwise by the Engineer in writing.
