Section 3: Anticipated Hazardous Materials Encountered during Construction
This section covers hazardous materials identified during earlier phases of the project development process, where preventive action has been incorporated into the project and/or provided for in the plans, specifications and estimates (PS&E).
Coordination
Coordination is necessary between the prime construction contractor
and specialty contractor(s), consultant(s) and other subcontractors,
to avoid duplicated activities or unnecessary downtime. Typically,
a specialty contractor or subcontractor under the guidance of an
environmental consultant will execute preventive action while working
with the prime construction contractor under the overall control
of the Engineer. Effective coordination between these parties and
their work is important. A Pre-Bid Conference or partnering meeting
should be considered. The Engineer should also consider phasing
(whether part of the original contract or not) to minimize scheduling
conflicts between the prime construction contractor and specialty
contractors.
Implement Provisions and Oversight
During construction, the provisions for worker and public
safety, as well as handling and disposal of hazardous materials
or wastes, must be implemented. The contract may provide special compliance
requirements for the handling, treatment or transportation of hazardous
materials, worker qualifications, and safety practices. These special
provisions should be high-lighted so the contractor and inspectors
are aware of them from the beginning. Specialized oversight provisions will
require the participation of consultants or environmental agencies.
Documentation
The district construction office and the Engineer are primarily
responsible for generating and maintaining a thorough record. During
construction, any actions taken for the sub-items related to preventive
action must be documented. Appropriate reports conclude the preventive
action phase of the project.
