FAR 49.105-4—Cleanup of construction site.
Plain-English Summary
FAR 49.105-4 addresses what must happen at a construction site after a contract has been terminated. It covers four related duties: cleanup of the site, protection of serviceable materials, removal of hazards, and any other action needed to leave the site safe and healthful. The rule exists because a terminated construction project can leave behind exposed materials, unstable work areas, debris, utilities, and other conditions that create safety, health, security, and property-loss risks. In practice, this section tells the contracting officer to take affirmative direction to stabilize the site and prevent further damage or injury, rather than simply ending the contract and leaving the site as-is. It is especially important where unfinished work, partially installed systems, stored materials, or hazardous conditions could affect workers, the public, the Government, or nearby property. The section is short, but it has immediate operational significance because site condition after termination can affect safety, salvage value, liability, and the cost and speed of completing or reprocurring the work.
Key Rules
Direct site cleanup
When a construction contract is terminated, the contracting officer must direct action to clean up the site. This means the site cannot be left in a disorderly or abandoned condition if cleanup is needed to protect people, property, or the Government’s interests.
Protect usable materials
The contracting officer must ensure serviceable materials are protected. Materials that can still be used, salvaged, or incorporated into future work should be secured and preserved to avoid loss, theft, weather damage, or deterioration.
Remove hazards
The contracting officer must direct removal of hazards created or left by the terminated work. This includes unsafe conditions such as debris, exposed utilities, unstable structures, open excavations, sharp objects, or other dangers that could injure workers or the public.
Make site safe and healthful
The contracting officer must take or direct any other action necessary to leave a safe and healthful site. This is a broad catch-all requirement that covers additional protective measures needed based on the specific site conditions, including sanitation, access control, environmental or occupational safety measures, and stabilization.
Responsibilities
Contracting Officer
Direct the actions needed to clean up the terminated construction site, protect serviceable materials, remove hazards, and take any additional steps necessary to leave the site safe and healthful.
Contractor
Carry out termination-related site protection, cleanup, hazard removal, and preservation of usable materials as directed by the contracting officer, consistent with the termination settlement and any stop-work or protective instructions.
Agency
Support the contracting officer in securing the site, arranging necessary cleanup or safety measures, and ensuring the site is managed in a way that protects Government property, personnel, and the public.
Practical Implications
A terminated construction site can become a safety incident if it is not quickly stabilized, so the contracting officer should act promptly rather than waiting for settlement issues to be resolved.
The rule is broader than simple debris removal; it also covers protecting salvageable materials and taking whatever additional steps are needed to make the site safe and healthful.
Common pitfalls include assuming the contractor will automatically secure the site, overlooking partially installed materials or utilities, and failing to address weather exposure, access control, or public hazards.
The site condition can affect termination costs, salvage value, and the ease of reprocurement, so documenting the site and directing protective measures early is important.
Because the standard is outcome-focused, the contracting officer should tailor directions to the actual hazards and conditions present at the site rather than relying on a one-size-fits-all approach.
Official Regulatory Text
In the case of terminated construction contracts, the contracting officer shall direct action to ensure the cleanup of the site, protection of serviceable materials, removal of hazards, and other action necessary to leave a safe and healthful site.
