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).
Anchor: #i1005613Coordination
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.
Anchor: #i1005628Implement 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.
Anchor: #i1005643Documentation
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.
