Substantial completion is defined as that point at which the work is basically complete and ready for use. All specified products shall have been installed and are functionally operational. Remaining work shall be extremely minor or require seasonal opportunity to complete or subject to delayed completion items and shall not impair the functionality of the site.

The Contractor shall notify the COR, in writing as required by the General Conditions, as to the date when in its opinion all or a designated portion of the work will be substantially completed and ready for inspection.

Within a reasonable time after receipt of such notice, the COR will inspect to determine status of completion.

Should the COR determine that the Work is not substantially complete:

The COR promptly will so notify the Contractor in writing, giving the reasons therefore.

Notify COR when ready for reinspection.

The COR will reinspect the Work.

The Contractor shall be liable for expenses incurred by the USFS for reason of such Substantial Completion Reinspection.

When the COR concurs that the Work is substantially complete:

The COR will prepare a Punch List of items to be completed or corrected.

The COR will submit the Punch List to the Contractor for their written acceptance of the responsibilities assigned to them in the Punch List.

Once the Contractor executes the Punch List, the COR must be notified in writing.

Immediately following approval of Substantial Completion, the Contractor shall submit the following documents.

Final Pay Request with final adjustment of accounts stating all adjustments to the contract sum.

Previous change orders.

Deductions or uncorrected work.

Other adjustments.

FINAL INSPECTION

Final Inspection: Final Inspection shall be defined as that period at which all work in the Contract is 100% complete and no minor details remain to be performed.

Final inspection shall not be made until all work under the contract is completed. The Contractor shall notify the COR in writing, at least 14 days prior to the date requested on which the work will be ready for final inspection.

Following notification, the COR will make an inspection of the Contractor's work and record any deficiencies on the Final Punch List. The Contractor shall immediately correct these deficiencies at their own expense and notify the COR in writing when all items have been corrected. The COR will re-inspect the work to assure correction of all deficiencies before release of amounts retained for minor, seasonal or delayed items. The Contractor shall be liable for all costs of reinspection when the Substantial Completion Punch List deficiencies have not been corrected at the time of the Final Inspection and reinspection is required.

Any reasonable delay by the COR in making final inspection shall not relieve the Contractor of responsibility for the work nor shall the USFS be held responsible for damages or claims for compensation on account of continuing overhead, maintenance, etc., occasioned by such a delay.

The Contractor, prior to requesting final payment, shall obtain and submit the following items to the COR for transmittal to the Government:

Written guarantees and warranties for materials and equipment.
