Our recent inspection of the work confirms that the work is complete. Under separate correspondence we are forwarding Change Order No. 2 which covers all remaining cost adjustment items and a previously recommended time extension. The Contractor has indicated that a request for final payment will be made after processing of Change Order No. 2. We see no reason not to process the final payment at this point pending the City's concurrence. By copy of this correspondence, we remind the Contractor that Consent of Surety for Final Payment and a statement that all Liens, if any, arising out of the work are released or waived, are required to be submitted with the request for final payment as indicated in General Conditions, Paragraph 14.12. Following substantial completion, we had listed a punch list item relative to the amount of water being pumped from the liner collection system drainage layer of each lagoon. As we have previously discussed, some amount of leakage is to be expected with this type of lagoon liner system and considering the design water level in each cell. Based on the pumping rate and monitoring well data provided by City staff, we find nothing that would indicate any problems with the performance of the liner or its installation. The amount of liquid pumped from the liner drainage layer has reduced significantly since the facility first went into service. This is to be expected because the initial pumping was removing moisture that collected during the construction. However, we do recommend that City staff continue to perform the pumping on a the imagine•build company*.

We will provide further comments relative to the monitoring well water sample data submitted and the City's lagoon operating permit under separate correspondence.
