Title
Recommendation to Accept the Work of Innovative Construction Solutions for the Alameda South Shore Lagoons 3 and 5 Dredging Project, No. P.W. 09-19-49. (Public Works 96007)
Body
To: Honorable Mayor and Members of the City Council
EXECUTIVE SUMMARY
On April 7, 2020, the City Council awarded a contract to Innovative Construction Solutions in the amount of $407,184, which included a 20% contingency, for the removal of accumulated sediment from the corners of Lagoons 3 and 5 of the South Shore lagoon system. Unforeseen extra work required an additional purchase order of $2,447 to complete the project. Sufficient funding was available in the Capital Improvement Program (CIP) Fund 96007 to pay for the additional expense with a total project cost of $409,631. The project has been completed and is acceptable to the Public Works Department.
BACKGROUND
The project included mechanically dredging the lagoon corners to remove accumulated sediment. The dredge spoils were loaded into trucks and hauled to suitable disposal sites that accepted the material. The dredging took place in August and September 2020 during the annual lowering of the lagoons for maintenance to minimize disturbance of the lagoons and lagoon water quality.
DISCUSSION
On April 7, 2020, the City Council awarded a contract to Innovative Construction Solutions in the amount of $407,184. Poor sediment consistency of the dredged material demanded use of additional soil desiccant to transport the material to the designated disposal facility. A purchase order for the additional soil desiccant cost ($2,447) was issued from CIP Fund 96007.
The project has been completed and is acceptable to the Public Works Department. The final project cost, including the additional soil desiccant tonnage of $2,447, is $409,631.
