Construction Contractors


  • This applies to any subcontractor of PPPL who is making changes or additions to on-site structures or equipment.

Statement of Work (SOW)

A SOW written for procurement of a construction contractor must include the following requirements for the contractor:
  1. Prepare a site-specific Health and Safety Plan (HASP). This is a document detailing the activities that the contractor will be engaged in, the hazards of those activities, and the control measures for the identified hazards. Note that a PPPL JHA may be used as a substitute for a HASP, as long as it includes all of the required information. Be sure there is a JHA for each major phase of the project. The JHAs or HASP must be approved by the PPPL Construction Manager.
    *Material Safety Data Sheets (MSDS) for any chemicals the contractor is bringing on site must also be supplied as part of the control measures for those chemicals.
  2. Any OSHA required drawings or specifications where a Professional Engineer or other qualified individual's approval is required. Examples would be very high scaffolds or very deep excavations.
  3. The identity and qualifications of any applicable Competent Persons. A competent person is able to recognize the hazards of the work and has the authority to make corrections as needed. Competent persons are required for all construction work, and certain regulations require competent persons for specific hazards such as fall protection or excavations.
  4. Document that all workers are aware of the hazards and control measures. This can be done by having all the subcontractor employees put their name on the back of the JHA form.
  5. Describe or provide the company policy ensuring that workers not following the safe work practices are subject to the contractor's disciplinary process.
  6. Identify a designated representative of the contractor who will be on site during all active construction and who makes frequent and regular inspections of the job site. Note that this person may also be the competent person as described above.
  7. Instruct all workers to report any safety concerns to the designated representative or competent person for action. This can be done with a pre-job brief and/or described in company policy. If corrective measures for the identified concern cannot be implemented immediately, Stop Work may be required.


Princeton Technical Representative

  • All contractors must have a Princeton Technical Representative (PTR) assigned. This person is responsible for administration of the contract to make sure that the subcontractor meets the specified requirements. PTRs must participate in training provided by the PPPL Procurement Division.

Construction Manager

A Construction Manager must be assigned to each construction project to make sure the work is done according to all safety standards. Some of the responsibilities of the Construction Manager are:
  • Hold meetings before the work begins to discuss the plans for the various activities. Work with all affected ES&H, Fire Protection and other subject matter experts to ensure that all safety requirements are met.
  • Review and approve the JHA's and other safety documents for the construction.
  • Hold an on-site pre-job brief for all of the contractor's workers, the PPPL ES&H representatives, and other affected personnel. Be sure everybody in attendance puts their name on the JHA.
  • Hold regular (preferably daily) meetings with the contractor to review the work and the plans for the day's activities.
  • Perform regular walk throughs of the work site to look for safety deficiencies and have them corrected or to Stop Work when necessary.

On-Site Construction Oversight

Frequently, the Construction Manager may require an individual to spend a large portion of their time overseeing the work and acting as liaison between PPPL and the contractor to make sure the work goes smoothly and all ES&H requirements are met. While not a Lab requirement, this is a good practice, especially when the work is complicated or has high safety risks.
